Glossary of terms
Assessment
A procedure used to generate data required by the study
Biologic Samples
A biological specimen including, for example, blood (plasma, serum), saliva, tissue, 
urine, stool, etc. taken from a study patient
Blinded Independent 
Review Committee
A third party review committee which provides an independent, unbiased and impartial 
assessment of disease response or progression for each patient enrolled in a clinical 
trial. The BIRC is blinded to all sites and subject identifying information as well as the 
results of the local assessment. Independent reviews of images and/or clinical data are 
performed independently of and separate from the reviews performed by investigators 
at clinical sites. Assessments from site investigators or other third party reviewers will 
not be provided to the image vendor since these evaluations may bias the image 
vendors’ reviewers’ assessments.
Cycles
Number and timing or recommended repetitions of therapy are usually expressed as 
number of days (e.g.: q28 days)
Enrollment
Point/time of patient entry into the study; the point at which informed consent must be 
obtained (i.e. prior to starting any of the procedures described in the protocol)
Investigational drug
The study treatment whose properties are being tested in the study; this definition is 
consistent with US CFR 21 Section 312.3 and is synonymous with “investigational new 
drug.”
Investigational 
treatment
Drug whose properties are being tested in the study as well as their associated 
placebo and active treatment controls (when applicable). This also includes approved 
drugs used outside of their indication/approved dosage, or that are tested in a fixed 
combination. Investigational treatment generally does not include other study 
treatments administered as concomitant background therapy required or allowed by 
the protocol when used in within approved indication/dosage
Medication number
A unique identifier on the label of each study treatment package which is linked to one 
of the treatment groups of a study
Other study 
treatment
Any drug administered to the patient as part of the required study procedures that was 
not included in the investigational treatment
Personal Data
Patient information collected by the Investigator that is transferred to Novartis for the 
purpose of the clinical trial. This data includes patient identifier information, study 
information and biological samples.
Subject Number 
(Subject No.)
A unique identifying number assigned to each patient who enrolls in the study
Period
A subdivision of the study timeline; divides stages into smaller functional segments 
such as screening, baseline, titration, washout, etc.
Stage in cancer
The extent of a cancer in the body. Staging is usually based on the size of the tumor, 
whether lymph nodes contain cancer, and whether the cancer has spread from the 
original site to other parts of the body
Stop study 
participation
Point/time at which the patient came in for a final evaluation visit or when study 
treatment was discontinued whichever is later
Study treatment
Includes any drug or combination of drugs in any study arm administered to the patient 
as part of the required study procedures, including placebo and active drug run-ins.
In specific examples, it is important to judge investigational treatment component 
relationship relative to a study treatment combination; study treatment in this case 
refers to the investigational and non-investigational treatments in combination.
Study treatment 
interruption 
Includes any delay or withholding of study treatment for any reason as well as an 
interruption during an infusion of study treatment for any reason
Study treatment 
discontinuation
Point/time when patient permanently stops taking study treatment for any reason
Variable
Identifier used in the data analysis; derived directly or indirectly from data collected 
using specified assessments at specified timepoints
Withdrawal of 
consent
Withdrawal of consent from the study occurs only when a patient does not want to 
participate in the study any longer, and does not allow any further collection of personal 
data

Amendment 3 (24-May-2018)
Amendment rationale
Recruitment into Part 1 of the study completed on 20-Sep-2017 with 116 patients (of 
approximately 110 planned) enrolled. A planned interim analysis as well as an additional 
efficacy analysis (to inform decision to start part 2) were performed with data cut-off dates of 
29-Nov-2017 and 09-Feb-2018, respectively. The key efficacy and safety results of the two 
analyses are summarized in Section 1.2.1.2. No new safety signals were identified in the interim 
analysis. As of 15-May-2018, recruitment into Part 2 has not opened and no patients were
enrolled into Part 2. 
The major rationale for protocol amendment 3 is to remove the possibility to expand the study 
to Part 2 when at least 20% overall response rate (ORR) per RECIST 1.1 by central radiology 
review is observed in any of the cohorts of the well-differentiated NET group. While the results 
of the additional efficacy analysis (Section 1.2.1.2) demonstrated an ORR of 20% in the thoracic 
cohort of the well-differentiated NET group and met the criterion for starting Part 2, no 
overwhelming supportive evidence of strong efficacy was observed on other endpoints. 
Moreover, all other cohorts showed ORR below 10%. Based on this, there was a change in the 
clinical development strategy for PDR001, which will no longer be developed as a single agent 
immunotherapy in NET, and the study will not be expanded into Part 2. Importantly, this change 
is not due to safety concerns.   
Due to revoking Part 2, no further patient will be enrolled in the study and the primary analysis 
will provide results for all enrolled patients. Consequently, the following modifications will be 
implemented after the primary analysis cut-off date (10-Aug-2018):

Tumor response assessments will be performed according to local or institutional 
standards of care and when clinically indicated.

Removal of tumor response assessments by the Blinded Independent Review Committee
(BIRC); tumor response will be assessed locally.

Removal of post-treatment efficacy follow-up. There will be no change to the safety 
follow-up or survival follow-up.

Removal of the Patient Reported Outcomes (PRO) data collection.
Additional changes to the protocol include:

Following the release of Investigator Brochure Edition 7.1, changes to the Risks and 
Benefit section have been implemented and the contraception requirement for male
participants has been updated. Condom use for males receiving monoclonal antibodies is 
no longer required since monoclonal antibodies are not genotoxic due to their high 
molecular weight, and are not expected to interact with DNA. In addition, they have a low 
distribution to the semen, a relatively small volume of semen is delivered to the vagina, 
and there is very low absorption. Fetal harm from semen delivery is therefore biologically 
implausible. 

Withdrawal of consent language was updated to reflect the European Economic Area 
General Data Protection Regulation (GDPR) requirements.

Editorial changes and text corrections were made for clarification, where required.

Summary of previous amendments
Amendment 2 (12-Jan-2018)
Amendment rationale 
The first patient signed the informed consent on 14 February 2017. As of 05 January 2018, 95
patients with well-differentiated non-functional NET and 21 patients with poorly differentiated 
GEP-NEC have been treated with at least one dose of PDR001. The enrollment in part 1 is 
completed and the study is currently ongoing. 
Amendment 2 includes the following modifications:

Inclusion of Part 2 (Expansion part) aiming to further characterize the efficacy and safety 
of PDR001 single agent in any of the well-differentiated NET cohorts if antitumor activity 
is observed in Part 1. Each of the well-differentiated cohorts (GI, thoracic, pancreatic) will 
enroll additional 60 patients if we observe at least 20% ORR per RECIST 1.1 and central 
radiology review in the corresponding cohort.

Possibility to implement the PDR001 liquid formulation for patients treated in Study Part 
2 (expansion part).Addition of an inclusion criterion regarding life expectancy of at least 3 
months for patients treated in Study Part 2. This would decrease the occurrence of deaths 
during the screening period and before the first tumor assessment scheduled 8 weeks after 
the first treatment dose. 
Rationale for possible expansion of Well-differentiated NET:
Well-differentiated, non-functional NETs of the thorax, gastrointestinal tract and pancreas are 
rare and heterogeneous, clinically important group of neosplasms with a different clinical 
management and available therapeutic options. The management of patients with metastatic 
NETs includes systemic and biological treatment strategies such as molecular targeted therapies 
with everolimus and sunitinib, PRRT and chemotherapy. PD-L1 expression emerged as a
potential prognostic factor for survival in NET; showing that patients with PD-L1 negative 
tumors experience a longer survival as compared to PD-L1 positive however limited data is 
available regarding the treatment effect of checkpoint inhibitors in NET (Kim 2016; Fan 2016; 

Novartis

Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
Mehnert 2017). There are no available treatment options with proven efficacy post everolimus 
failure and a limited number of agents approved specifically in NET of GI and lung origins,
representing an unmet need. Considering the high level of heterogeneity between different NET 
origins, if an activity signal is observed in any of the 3 cohorts, an expansion in the sample size 
will be performed to better assess the efficacy of PDR001 in that specific NET subgroup.

Amendment 1 (27-Apr-2017) 
Amendment rationale 
The first patient signed the informed consent on February 14, 2017. As of 24-Apr-2017, 7
patients have been treated with at least one dose of PDR001.  
Amendment 1 includes the following modifications:

Adding a group of approximately 20 patients with advanced or metastatic, poorly-
differentiated gastroenteropancreatic neuroendocrine carcinoma (GEP-NEC). This cohort 
is added because of the following reasons: 1) biological rationale supporting the potential 
efficacy of immunotherapy; 2) currently there is no approved treatment and no consensus 
on the standard of care upon progression on 1st line chemotherapy.   

Removing the possibility of stopping the study early for futility at the time of the protocol 
defined interim analysis. By the time of the planned interim analysis, enrollment is 
expected to be completed. A formal interim analysis of preliminary efficacy and safety 
data will be kept, but the study will not be stopped for efficacy reasons regardless of 
efficacy results and the study will continue until mature data for all patients become
available.

Modifying the inclusion criterion 4 and adding exclusion criterion 27. “No history of 
carcinoid syndrome” was removed from this inclusion criterion since this condition may
be present during the course of the disease but may have resolved with appropriate 
treatment and therefore not present at the time of enrollment. A period of 3 months 
without any evidence of carcinoid symptoms and somatostatin analogs treatment has been 
defined prior to study entry. 

Modifying the inclusion criterion 9. The tumor sample should be taken within 6 months 
but not more than 24 months (instead of 12 months) prior to start of study treatment. 
Extending the collection period from a maximum of 12 months to 24 months improves 
recruitment 
 
.

Adding exclusion criterion 26. Interstitial lung disease was observed in ongoing PDR001 
studies.

Removing the maximum treatment duration of 24 months. The limit on treatment duration 
is removed to provide the option of continuing study treatment for those patients who 
present clinical benefit and have not progressed during the first 24 months of treatment 
and still fulfils the criteria to continue study treatment.   

Extending the treatment window from +/- 4 days to +/- 7 days based on investigators’ 
feedback that more time is required between routine blood collection and start of study 
treatment.

Modifying the exclusion criteria 13 for QTcF from > 450 to > 480 msec on screening 
ECG or congenital long QT syndrome because monoclonal antibodies such as PDR001 
have low potential for QT prolongation.

Updating safety information according to release of Investigator Brochure edition 6

Clarifying the definition of on-treatment period for safety analysis to align reporting with 
data collection. Main safety analysis will be performed based on data collected up to 30 

Novartis

days after discontinuation of study treatment. Additional analyses will be performed to 
report data up to 150 days after discontinuation of PDR001.

Purpose and 
rationale
● Although many advances with checkpoint inhibitors have been made in other tumor 
types, the data generated in NETs is limited with no clinical experience available to 
date. Recent correlative studies conducted in NETs have assessed the expression of 
PD-L1 and correlated tumor differentiation with poor clinical outcome. 
● Tumor-infiltrating lymphocytes (TILs) have been shown to predict survival in 
numerous malignancies. A robust T cell infiltration is associated with improved RFS 
following resection of intermediate-grade NETs, whereas the presence of a tumor 
environment rich in Tregs correlated with shorter OS after treatment. These findings 
suggest that the immune-modulation of the phenotype of T cells may play a role in 
clinical outcome.  
● Clinical data available from one patient with histologically confirmed metastatic 
atypical pulmonary carcinoid treated in the ongoing phase I study with PDR001 in solid 
advanced tumors [CPDR001X2101] showed an immune-related partial response with 
dramatic resolution of multiple liver and pleural metastases. Patient has been on 
therapy for nine months, and at the last tumor imaging assessment a sustained partial 
response according to RECIST 1.1 criteria was observed with sustained regression in 
all areas of tumor.
Primary Objective 
and Key 
Secondary 
Objective
Primary objective:
●To estimate the antitumor activity (assessed as ORR per RECIST 1.1) of PDR001 as 
a single agent in the well-differentiated NET and the poorly-differentiated GEP-NEC 
groups.
Key secondary objective:
● To estimate efficacy (DoR per RECIST 1.1) of PDR001 in the well-differentiated NET 
and poorly-differentiated GEP-NEC groups.   
Secondary 
Objectives
Other secondary 
● To assess the safety and tolerability of PDR001 in each group and in the overall 
study population.
● To evaluate in each group additional efficacy parameters per RECIST 1.1 and per 
Immune Response Criteria irRECIST as well as 1-year and 2-year OS rate
● To evaluate biochemical response to treatment (based on CgA and NSE) in each 
group
● To characterize the pharmacokinetics of PDR001 with 400 mg flat dose Q4W in 
each group
● To characterize patient’s health-related quality of life with PDR001 in each group
● To evaluate the prevalence and incidence of immunogenicity in each group
Study design
This is a phase II, single-arm, open-label, multi-center study.
Population
Patients with unresectable advanced or metastatic, well-differentiated, non-functional 
NETs of GI, pancreatic or thoracic origin, or poorly-differentiated GEP-NEC who have 
progressed on or after prior available treatments. 
● A total of approximately 90 patients will be enrolled in the well-differentiated group, 
with approximately 30 patients enrolled in each cohort based on tumor origin. 
Approximately 20 patients will be enrolled in the poorly-differentiated GEP-NEC group, 
for a total number of approximately 110 patients.

Data analysis
No formal hypothesis testing will be used for the primary analysis. The primary efficacy 
variable of the study is overall response rate (ORR), defined as the proportion of 
patients with best overall response (BOR) of complete response (CR) or partial 
response (PR), as per RECIST 1.1 and blinded independent central review. 
● Well-differentiated NET Group:
The response rate on all patients with 95% two-sided confidence interval (exact 
method) will be computed. In the absence of an established control treatment, ORR 
reported in the placebo arms of studies in NET can serve as a reference. A 3% ORR is 
therefore considered as a reasonable reference while an improvement up to 10% is 
considered as clinically meaningful in this patient population.
The study will be considered a success in this group if both of the following conditions 
are met:
a. a clinically relevant response rate of at least 10% is observed
b. 95% two-sided CI for ORR excludes the value 3%. 
● Poorly-differentiated GEP-NEC Group:
Estimates of the ORR along with 95% confidence intervals will be presented and the 
interval probabilities for the true ORR lying within the intervals stated below will be 
assessed:
0 - <3% unacceptable efficacy
3% - <10% limited efficacy
10% - <20% moderate efficacy
20% clinically relevant efficacy.

Background
1.1
Overview of disease pathogenesis, epidemiology and current 
treatment
Neuroendocrine tumors (NETs) are heterogeneous entities with a pathological interrelation 
originating from the diffuse neuroendocrine cell system. While NETs are not frequent, their 
prevalence has been increasing over the last 20 years (Yao 2008). Furthermore, their incidence 
has also increased, rising to 5 per 100,000 in recent years from 1 per 100,000 in the early 1970s 
(Dong 2012). However, it is not fully proven that this increase is a result of better recognition 
of these pathologic entities or rather a true increase of the incidence of the disease. NETs can 
be further sub classified according to their embryologic origin: hindgut (rectum and distal 
colon), midgut (proximal large bowel, ileum, appendix and jejunum) and foregut (stomach, 
duodenum, thymus and lung) (Dong 2012). The majority of NETs are located in the gastro-
intestinal (GI) tract (more than 60% of all NETs and they are also known as 
gastroenteropancreatic NETs [GEP-NETs]) or in the lungs (almost 30%). The most frequent 
sites of primary GEP-NET are the: small intestine (28%), appendix (20%), pancreas (16%), 
rectum (15%), colon (13%) and stomach (9%). Distant metastases at diagnosis are relatively 
rare for primary tumors of the appendix (3%), rectum (6%) and stomach (15%); whereas the 
metastases are more frequent for small intestine (45%), pancreas (42%) and colon (40%) 
(Frilling 2014).
Neuroendocrine tumors are classified into 3 broad histologic categories based on tumor 
differentiation: well-differentiated (G1); intermediate-grade (G2); and poorly-differentiated, 
high grade tumors (NCCN Guidelines V1.2017). Neuroendocrine carcinomas represent 
approximately only 15% of all NETs (Yao 2008). Tumor differentiation and tumor grade often 
correlate with mitotic count and Ki-67 proliferation index (Kloppel 2010; Rekhtman 2010). The 
gastroenteropancreatic (GEP) tract is the most common site of extrapulmonary NET accounting 
for 35% to 55% of all neuroendocrine tumors originating from the lung (Garcia Carbonero 
2016).
The classification of neuroendocrine tumors in functioning or non-functioning is based on the 
presence of symptoms that accompany these syndromes secondary to the secretion of hormones, 
neuropeptides, and/ or neurotransmitters (functioning tumors). Non-functioning tumors are 
considered to be neoplasms of neuroendocrine differentiation that are not associated with 
symptoms attributed to the hypersecretion of metabolically active substances. Presentation of 
non-functional tumors is either due to an incidental finding or a tumor mass effect (Gut 2015).
Well-differentiated NETs are characterized by an indolent course; however, curative surgery is 
often not possible because the majority of patients present with metastatic disease at the time 
of diagnosis, with regional or distant tumor spread seen in 50% of patients (Yao et al 2008).
Poorly-differentiated neuroendocrine carcinomas are characterized by a high proclivity to 
metastatic dissemination even in patients with localized tumors (Strosberg 2010). 
Approximately two thirds of patients present with advanced disease dominated by site-specific 
tumor-derived symptoms and a syndrome characteristic of advanced cancer (anorexia, weight 
loss and fatigue) (Strosberg 2010).

1.1.1
Current treatment options
In patients with well-differentiated G1 or G2 inoperable NET, the treatment goal is to control 
secretory symptoms (if the tumor is functional), to control tumor growth, and to prolong 
survival. Biotherapy with somatostatin analogs (SSAs) remains the mainstay of symptomatic 
therapy as well as an active treatment to control disease burden in well differentiated NET of 
lung, GI or pancreatic origin (NCCN Guidelines v13 2015; Igarashi 2015; Noel-Savina 2013). 
Specifically with regards to gastrointestinal NET, different studies have assessed SSA treatment 
demonstrating superiority versus placebo: 

PROMID study included treatment-naive patients with metastatic midgut NET; results 
showed that octreotide LAR (long-acting release) increased time to tumor progression 
(TTP) when compared to placebo from 6 months to 14.3 months (p=0.000072) (Rinke 
2009). 

CLARINET study included patients with advanced, well or moderately differentiated, 
nonfunctioning, non-progressing GEP-NET; results showed that lanreotide treatment was 
associated with significantly prolonged median PFS (mPFS) when compared to placebo 
(not reached vs. 18.0 months, p<0.001) (Caplin 2014).
The phase III NETTER-1 study confirmed the efficacy of peptide radionuclide receptor therapy 
(PRRT) in patients with well-differentiated midgut NETs after failure of octreotide treatment. 
This study evaluated 177Lu-DOTATATE plus octreotide LAR vs. octreotide LAR. The mPFS 
was 8.4 months with octreotide LAR and the median PFS was not reached with 177Lu-
DOTATATE (HR = 0.21; P < .0001). The estimated rate of PFS at month 20 was 65.2% (95% 
CI, 50.0 to 76.8) in the 177Lu-DOTATATE group and 10.8% (95% CI, 3.5 to 23.0) in the 
control group. Tumor response rate was 3% and 18.8% with octreotide LAR and 177Lu-
DOTATATE,
respectively (Strosberg 2016,
Strosberg 2017). In Sep-2017, 177Lu-
DOTATATE received approval in the EU for the treatment of unresectable or metastatic, 
progressive, 
well 
differentiated 
(G1 
and 
G2), 
somatostatin 
receptor 
positive 
gastroenteropancreatic neuroendocrine tumours (GEP-NETs) in adults. In Feb-2018 177Lu-
DOTATATE received FDA approval for the treatment of somatostatin receptor-positive GEP-
NETs, including foregut, midgut, and hindgut neuroendocrine tumors in adults.
Limited antineoplastic therapy options are currently available for patients with progressive 
metastatic NET of GI and lung origin:

RADIANT-2 study included patients with advanced functional NET and assessed 
everolimus-octreotide vs. placebo-octreotide. Results showed a mPFS of 16.4 months 
(95% CI 13.7–21.2) in the experimental arm vs. 11.3 (8.4–14.6) months in the placebo 
arm (HR 0.77, 95% CI 0.59–1·00; p=0.026) (Pavel 2011). 

Cytotoxic therapy appears to provide a modest benefit. Although different agents have 
been evaluated (including capecitabine, temozolamide, streptozocin, doxorubicin), 
response rates are generally low and no PFS benefit have been clearly demonstrated 
(NCCN guidelines 2015).  

RADIANT-4 study included patients with advanced, progressive non-functional NET of 
GI or lung origin. Everolimus demonstrated superiority over placebo in terms of PFS 
showing a 52% relative risk reduction of progression/death in favor of everolimus (HR: 
0.48; 95% CI: 0.35, 0.67) (p<0.001) (Yao 2016). Based on these results, submissions

worldwide have thus far led to marketing authorization of everolimus in progressive, 
nonfunctional NET of GI or lung origin in over 41 countries including the US, EU, 
Canada, and Japan.
The systemic treatment options for non-functional advanced pancreatic NET (PNET) include 
chemotherapy, somatostatin analogs and targeted agents such as everolimus and sunitinib. Both 
targeted agents, sunitinib and everolimus, are approved by health authorities worldwide for the 
treatment of advanced PNET based on the pivotal studies described below:

RADIANT-3 study included patients with advanced and progressive PNET and assessed 
everolimus vs. placebo (Yao 2011). The study results showed that mPFS was 11.0 months 
with everolimus as compared with 4.6 months with placebo (HR=0.35; P<0.001). Subset 
analyses of RADIANT-3 showed that the PFS effect of everolimus was independent of 
prior or concurrent SSA therapy or chemotherapy.

A randomized phase III study evaluated sunitinib in patients with progressive metastatic 
PNET. The study was stopped before the predefined analysis; the investigator-assessed 
mPFS for sunitinib arm was 11.4 months compared to 5.5 months in the placebo arm, 
resulting in a HR of 0.42 (p=0.0001) (Raymond 2011). 

Furthermore, cytotoxic therapy (including streptozocin, temozolamide, doxorubicin, 
dacarbazine) has been assessed in a number of regimens in PNET yielding response rates 
in the range of 8%-39% with limited long-term disease control. As of today, there is no 
panel consensus on which cytotoxic regimen is preferred (NCCN 2015). Streptozocin is 
the only FDA-approved agent among the cytotoxic agents for use in patients with 
advanced PNET.
Recently, the Keynote 028 study reported results of pre-treated patients with PD-L1-positive, 
advanced carcinoid (=25) or PNET (=16) treated with pembrolizumab as single agent. The 
study results showed an ORR of 12% and 6% in carcinoid group and PNET group, respectively 
(no Complete Response was observed). The majority of patients have stable disease as best 
overall response, in 60% and 88% in carcinoid group and PNET group, respectively. The 
duration of disease stabilization was above 6 months in 32% of patients with carcinoid tumors 
and 31% of patients with PNET. The mPFS in carcinoid group was 5.6 months (95% CI, 3.5 to 
10.7) and in PNET group was 4.5 months (95% CI, 3.6 to 8.3); the mOS observed in both 
cohorts was 21 months (Mehnert 2017).

The treatment strategies of poorly-differentiated neuroendocrine carcinoma are often 
extrapolated from the treatment paradigm of small cell lung cancer (SCLC) (Sorbye 2014). 
There are no prospective studies conducted in gastroenteropancreatic neuroendocrine 
carcinoma (GEP-NEC), most of the studies reported are retrospective with limited sample size. 
Based on its established role in SCLC, cisplatin and etoposide is the most widely used regimen 
in GEP-NET in the front line setting with response rates in the range of 42% to 67% and median 
survival of approximately 15 to 19 months (Moertel 1991; Mirty 1999). More recent data 
suggest that the clinical outcome in patients with GEP-NEC may be worse than previously 
reported. In a retrospective study, 252 patients with advanced GEP-NEC received 
cisplatin/etoposide or carboplatin/ etoposide (Sorbye 2013) reporting an ORR of 31%, median 
PFS of 4 months with a median survival of 11 months. No differences in outcome were observed 
when comparing cisplatin-based treatment versus carboplatin-based treatment. Upon 
progression on front line platinum based therapy, no standard therapy has been established for 
GEP-NEC. Retreatment with cisplatin is an option as well as different regimens are considered 
(including FOLFOX, XELOX, temozolamide plus capecitabine) as well as single agent therapy 
(including temozolamide, irinotecan, taxanes or amrubicin) (Garcia-Carbonero 2016). On small 
retrospective studies, the response rates ranges from 18% to 31%; with a median PFS of 
approximately 4 months and survival in the range of 6 to 9 months (Hadoux 2013; Hentic 2012; 
Olsen 2012).

Introduction to investigational treatment(s) and other study 
treatment(s)
1.2.1
Overview of PDR001 
PDR001 is a high-affinity, ligand-blocking, humanized IgG4 antibody directed against 
Programmed Death-1 (PD-1) receptor that blocks the binding of PD-L1 and PD-L2. PD-1 is a 
critical immune-checkpoint receptor that is expressed on CD4 and CD8 T cells upon activation 
(Freeman 2008). Engagement of PD-1 by its ligands, PD-L1 and PD-L2, transduces a signal 
that inhibits T-cell proliferation, cytokine production, and cytolytic function (Riley 2009). 
Monoclonal antibody (mAb) inhibitors of immunological checkpoints, including PD-1 and PD-
L1, have demonstrated significant antitumor activity in patients with various solid tumors. For 
further details please refer to the latest PDR0001 [Investigator’s Brochure].
1.2.1.1
Non-clinical experience of PDR001
PDR001 binds specifically and with high affinity to human PD-1 and enhances interleukin-2 
production in ex-vivo lymphocyte stimulation assays. It does not cross react with rodent PD-1; 
therefore, toxicology studies were performed only in cynomolgus monkeys where there was 
acceptable cross reactivity with monkey PD-1. Repeat administration of PDR001 to monkeys 
was tolerated at all doses tested up to 100 mg/kg/week for 5 weeks in the GLP toxicology single-
agent study. No test article-related in-life, mortality, organ weight changes, or macroscopic 
findings were noted. There were no PDR001-related effects seen in any of the safety 
pharmacology endpoints assessed (cardiovascular, neurobehavioral, and respiratory). 
Macrophage infiltrates into the splenic white pulp were observed in animals given 100 
mg/kg/week and mononuclear cell infiltrates, often associated with fibrosis, around the 
injection site blood vessel (saphenous vein) in a few animals given ≥25 mg/kg/week. These 
PDR001-related microscopic changes were fully reversible after an eight week recovery. 
Additionally, mostly low grade mononuclear infiltrates in the vascular and perivascular space 
in several tissues of main and recovery treated animals and in recovery controls were observed 
but with a slightly higher incidence in treated animals. No evidence of parenchymal damage 
was associated with the vascular/perivascular changes in any of the organs examined and the 
changes were not associated with any frank tissue injury. Dose-proportional exposure to 
PDR001 in each dose group was confirmed. Anti-drug antibodies (ADA) to PDR001 were 
observed in some PDR001 treated cynomolgus monkeys. A trend of reduced drug exposure was 
observed in these ADA-positive animals. Based on the toxicology studies with PDR001 as a 
single-agent, the Highest Non-Severely Toxic Dose (HNSTD) dose is 100 mg/kg. For further 
details, please refer to the latest PDR001 [Investigator’s Brochure].
1.2.1.2
Clinical experience of PDR001
At the time of the release of the protocol amendment 2; three studies assessing PDR001 single 
agent in patients with advanced solid tumors as well as other malignancies (including melanoma, 
non-small cell lung cancer, triple negative breast cancer and anaplastic thyroid cancer) have 
reported preliminary safety data included in the Investigator Brochure version 6.

CPDR001X2101 Study:
A summary of preliminary clinical safety information reported from the first-in-human study is 
provided below (cut-off date 14-Nov-2016):
A total of 160 patients were exposed to PDR001 single-agent. In the phase I part of the study, 
58 patients had been treated at doses of 1 mg/kg Q2W (16 patients) for up to 78 weeks, 3 mg/kg 
Q2W (15 patients) for up to 60 weeks, 10 mg/kg Q2W (11 patients) for up to 34 weeks, 3 mg/kg 
Q4W (6 patients) for up to 33 weeks and 5 mg/kg Q4W (10 patients) for up to 57 weeks. In the 
phase II part of the study, 102 patients had been treated in five groups: NSCLC 400 mg Q4W 
(33 patients), NSCLC 300 mg Q3W (1 patient), melanoma 400 mg Q4W (24 patients), TNBC 
400 mg Q4W (40 patients) and anaplastic thyroid cancer 400 mg Q4W (4 patients). In the phase 
II part of the study, the median duration of exposure to study treatment was 8.0 weeks (range 
1.0 - 35.1). No Dose Limiting Toxicities (DLTs) were reported. One-hundred twenty seven 
patients (79.4 %) have permanently discontinued study treatment, 5 due to an AE, 97 due to 
progression of disease, 8 due to subject/guardian decision, 4 due to physician decision and 13 
due to death. None of the deaths were attributed to study treatment. 
Of the 160 patients treated, 79 (49.4 %) experienced AEs (all grades) suspected to be related to 
study treatment. Most frequent suspected AEs (≥ 5 % of patients) included fatigue (24 patients, 
15.0 %), nausea (14 patients, 8.8 %), pruritus (13 patients, 8.1 % ), diarrhea (12 patients, 7.5 %) 
and hypothyroidism (10 patients, 6.3 %). Of the 160 patients treated, 84 (52.5 %) experienced 
grades 3 or 4 AEs regardless of relationship to study drug. Of these grades 3/4 AEs, the 
following were suspected to be related to study treatment: two cases of vomiting and individual 
cases of increased ALT, increased AST, hypocalcemia, increased lipase, autoimmune hepatitis, 
autoimmune colitis, nausea, hyperglycemia, decreased lymphocyte count, and decreased weight. 
SAEs regardless of relationship to study drug, were reported in 61 (38.1 %) patients. Seven 
serious adverse events (SAEs) were observed in five patients were suspected to be related to 
study treatment per investigator’s assessment. 
CPDR001X1101 Study:
A summary of preliminary clinical safety information reported from this study conducted in 
Japanese patients with solid tumors is provided below (cut-off date 25-Nov-2016):
Eighteen patients had been enrolled and treated with PDR001 at doses of1 mg/kg Q2W (6 
patients) for up to 27 weeks, 3 mg/kg Q2W (6 patients) for up 28 weeks, and 10 mg/kg Q2W 
(6 patients) for up to 14 weeks. No DLTs were reported. Sixteen patients (88.9 %) have 
permanently discontinued study treatment, 2 patients (11.1 %) due to an AE, 6 patients (33.3 %) 
due to progression of disease, and 8 patients (44.4 %) due to physician or subject/guardian 
decision. AEs suspected to be related to study treatment: Of the 18 patients treated, 11 patients 
(61.1 %) experienced AEs (all grades) suspected to be related to study treatment. The most 
frequent suspected (≥ 10 % of patients) AEs included maculo-papular rash (4 patients, 22.2 %), 
ALP increased (2 patients, 11.1 %) and malaise (2 patients, 11.1 %). Of the 18 patients treated, 
nine patients (50.0 %) experienced grade 3 or grade 4 AEs regardless of relationship to study 
drug. Of note, one grade 3 ALT increased and one grade 3 creatine phosphokinase increased 
were suspected to be related to study treatment. SAEs, all grades, regardless of relationship to 
study drug, were reported in 7 (38.9 %) patients. Two SAEs (grade 2 myositis and grade 1

interstitial pneumonia) were suspected to be related to study treatment per investigator’s 
assessment.
CPDR001X2201 Study: 
A summary of preliminary clinical safety information reported from this study conducted in 
patients with nasopharyngeal carcinoma is provided below (cut-off date: 02-Dec-2016):
Thirty-two patients had been enrolled and treated with PDR001 at the dose of 400 mg Q4W for 
up to 23 weeks. Fourteen patients (43.8 %) have permanently discontinued study treatment, 11 
(34.4 %) due to progression of disease, 1 (3.1 %) due to physician decision, 1 (3.1 %) due to 
subject/guardian decision and 1 (3.1 %) due to death (caused by progressive disease). Eighteen 
(56.3 %) patients are still on treatment. Of the 32 patients treated, 16 (50%) experienced AEs 
(all grades) suspected to be related to study treatment. The most frequent suspected AEs 
included fatigue, pyrexia, rash and hyponatremia (each in 3 patients, 9.4%), pneumonia, 
asthenia, decreased appetite and malaise were observed in 2 patients (6.3%). Of the 32 patients, 
11 (34.4 %) experienced grade 3 or grade 4 AEs regardless of relationship to study drug. Grade 
3 or 4 AEs suspected to be related to PDR001 were observed in 5 (15.6 %) patients. These 
included 3 patients with hyponatremia (9.4 %), 2 patients with pneumonia (6.3 %) and 1 patient 
with decreased appetite (3.1 %). SAEs, all grades, regardless of relationship to study drug, were 
reported in 7 (21.9 %) patients treated with PDR001. Three patients experienced an SAE 
suspected to be related to study drug.
For additional details on the monotherapy studies above mentioned or on ongoing studies with 
PDR001 in combination with other agents, please refer to the PDR001 Investigator Brochure.
CPDR001E2201 Study: Results of the interim and additional efficacy analysis
Planned interim analysis was performed with a data cut-off of 29-Nov-2017 after approximately 
30 patients in the well-differentiated NET group had undergone the first 3 radiological 
assessments, had shown disease progression, or had discontinued efficacy follow-up for any 
other reason. The full analysis set included 95 patients in the well-differentiated NET group (30 
patients in the thoracic cohort, 33 patients in the pancreatic cohort and 32 patients in the GI 
cohort) and 21 patients in the poorly-differentiated GEP-NEC group. Median duration (range) 
of follow-up (from treatment to data cut-off date) was 5.3 months (3.7-8.5 months) and 3.6 
months (2.3-4.6 months) in the well-differentiated NET and poorly-differentiated GEP-NEC 
groups, respectively. With this limited follow up, the overall response rate (ORR) per RECIST 
1.1 based on central radiology review was 3.2% in the well-differentiated NET group (10.0 % 
in the thoracic cohort, 0% in the pancreatic cohort, and 0% in the GI cohort) and 0% in the 
poorly-differentiated GEP-NEC group.
Safety analysis excluded events occuring 30 days after study treatment discontinuation. The 
most common adverse events (AEs) (≥15% in all patients; all grades) reported at the time of 
the interim analysis were fatigue (34.7% in well-differentiated NET cohort and 14.3% in
poorly-differentiated GEP-NEC cohort), pyrexia (25.3% and 9.5%, respectively), diarrhea (20.0% 
and 14.3%, respectively), nausea (16.8% and 28.6%, respectively), abdominal pain (18.9% and 
9.5%, respectively), and constipation (16.8% and 14.3%, respectively). The most common 
grade 3/4 AEs (≥2 of patients in each group) in well-differentiated NET cohort were abdominal 
pain and anemia (each in 4 patients), hypertension (3 patients), and fatigue and dyspnoea (each

in 2 patients). Abdominal pain, cough and back pain (each in 2 patients) were the most common 
grade 3/4 AEs in poorly-differentiated GEP-NEC cohort. No fatal SAEs were reported at the 
time of this analysis. 
An additional efficacy analysis was performed with a data cut-off of 09-Feb-2017. The ORR 
per RECIST 1.1 based on central radiology review, was 7.4% (7 patients with partial response 
[PR]) in the well-differentiated NET group and 4.8% (1 patient with PR) in the poorly-
differentiated GEP-NEC group. In the well-differentiated NET group, the ORR in 3 different 
cohorts were: 20.0% in the thoracic cohort (6 patients with PR of 30 evaluated; assessments of 
response duration was limited by the 2 deaths observed among 6 responders), 3.0% in the 
pancreatic cohort (1 patient with PR of 33 evaluated), and 0 in the GI cohort (of 32 evaluated; 
however, 1 unconfirmed PR was reported in the GI cohort at the time of the cut-off). 
The study is ongoing and further assessments for efficacy and safety continue. The primary 
analysis of the study will be performed 1 year after Last Patient First Treatment (LPFT) in the 
initially enrolled well-differentiated NET group.

Rationale
2.1
Study rationale and purpose
During tumorigenesis, cancer cells from a wide range of tumor types exploit immune 
checkpoint pathways, such as PD-1, to avoid detection by the adaptive immune system (Murphy 
2011). Blockade of the PD-1 pathway has been shown to lead to increased numbers of effector 
T cells through induction or expansion, and to improved cytolytic activity towards tumors. 
Additionally, PD-1 blockade is associated with a reduced numbers of regulatory T cells (Tregs) 
at the tumor site (Wang 2009, Mangsbo 2010).
Monoclonal antibody (mAb) inhibitors of immunological checkpoints, including anti-PD-1 and 
anti-PD-L1, have demonstrated significant antitumor activity in patients with various solid 
tumors. Two mAbs targeting PD-1, pembrolizumab and nivolumab, have demonstrated 
significant single agent activity in melanoma, non-small cell lung cancer, renal cancer, head 
neck cancer and Hodgkin's lymphoma among other solid tumors (Topalian 2012, Hamid 2013b, 
Topalian 2014, Seiwert 2014, Motzer 2015, Gillison 2016; Ansell 2015). 
Although many advances with checkpoint inhibitors have been made in other tumor types, the 
data generated in NETs is limited with no clinical experience available to date. Recent 
correlative studies conducted in NETs have assessed the expression of PD-L1 and correlated 
tumor differentiation with poor clinical outcome (Kim 2016; Cives 2016). 
Tumor-infiltrating lymphocytes (TILs) have been shown to predict survival in numerous 
malignancies. The importance of TILs in PNET and NET with liver metastases was assessed 
by immunohistochemistry (IHC) in a cohort of 126 patients who had undergone resection. 
Analysis of intermediate-grade NETs indicated that a dense T cell (CD3+) infiltrate was 
associated with a median relapse-free-survival (RFS) of 128 months compared with 61 months 
for those with low levels of intratumoral T cells infiltrate (P = 0.05, univariate analysis). 
Examination of liver metastasis revealed that a low level of infiltrating regulatory T cells (Treg, 
FoxP3+) was a predictor of prolonged survival (P < 0.01, univariate analysis). Therefore a

robust T cell infiltration is associated with improved RFS following resection of intermediate-
grade NETs, whereas the presence of a tumor environment rich in Tregs correlated with shorter 
OS after treatment (Katz 2010). These findings suggest that the immune-modulation of the 
phenotype of T cells may play a role in clinical outcome.  
PD-L1 and PD-1 expression was assessed by immunohistochemical analysis in tumor samples 
of 80 patients with lung NET showing a 59% and 51.3% expression rate, respectively (Fan 
2016). A similar analysis was conducted on 20 corresponding cancer-adjacent tissue specimens 
revealing an expression rate of 25% and 20% for PD-L1 and PD-1, respectively. PD-L1 
expression was significantly related to tumor stage and histological type (carcinoids, SCLC, 
LCNEC) (p=0.014). Survival analysis demonstrated a correlation with PD-L1 expression in 
tumor cells (8.9 months in PD-L1 Positive vs. 25.6 months in PD-L1 Negative); this correlation 
was also observed in tumor in TILs (8.9 months in PD-L1 Positive vs. 26.8 months in PD-L1 
Negative). This results suggest that PD-L1 expression can be useful prognostic marker for 
survival.
PD-L1 expression on tumor cells was analyzed by immunohistochemistry in 32 patients with 
GEP-NET showing a 22% expression rate in tumors (Kim 2016). PD-L1 expression was 
significantly associated with high-grade tumors (p=0.008). Moreover, the status of PD-L1 
expression could predict survival; the median overall survival (mOS) was 16.0 months in 
patients with PD-L1–positive tumors and 24.8 months in those with PD-L1 negative tumors
(p=0.037).
Clinical data available from one patient with histologically confirmed metastatic atypical 
pulmonary carcinoid treated in the ongoing PDR001 phase I study in solid advanced tumors 
[CPDR001X2101] showed an immune-related partial response with resolution of multiple liver 
and pleural metastases. The patient is a non-smoker, and tumor histology has been confirmed 
by central pathology as consistent with atypical carcinoid. Interestingly, tumor from this patient 
harbored 19 non-synonymous mutations only on the whole exome sequencing, suggesting that 
mutational burden in carcinoid tumors may not be the main driver of response to immune 
checkpoint inhibitors therapy. Patient has been on therapy for nine months, and at the last tumor 
imaging assessment a sustained partial response according to RECIST 1.1 criteria was observed 
with sustained regression in all areas of tumor (Naing 2016).
2.2
Rationale for the study design
A single arm study with a primary endpoint of overall response rate (ORR) with supportive key 
secondary endpoint of duration of response (DoR) is proposed to assess the safety and efficacy 
of PDR001 in two different groups of patients:

Patients with well-differentiated (G1 or G2) non-functional, unresectable advanced or 
metastatic NETs of GI, pancreatic or thoracic origin who have progressed on or after prior 
available treatments. 

Patients with advanced or metastatic poorly-differentiated GEP-NEC who have progressed 
on or after one prior chemotherapy regimen. 
A total of approximately 90 patients will be enrolled in the well-differentiated group, with 
approximately 30 patients enrolled in each cohort based on tumor origin. Approximately 20 
patients will be enrolled in the poorly-differentiated GEP-NEC group.

For patients with well-differentiated non-functional NET who present with disease progression 
after treatment with prior therapy (SSAs, cytotoxic agents and/or targeted therapies depending 
on the anatomical tumor site), there are currently no approved therapies improving the clinical 
outcome (Section 1.1). For patients with poorly-differentiated GEP-NEC no treatments are 
currently approved and currently there is no consensus with regards to the standard of care upon 
progression on first line treatment which typically consists of chemotherapy.   
In the absence of an established treatment to be considered as control, and based on the fact that 
ORR endpoint is appropriate to detect early signs of efficacy in the absence of a control (see 
below), a single arm study design has been proposed. 
A single arm design with an endpoint of ORR with DoR as a key secondary endpoint has been 
utilized as a primary means of evaluation in disease settings where an appropriate comparator 
may not necessarily exist or where currently available therapy does not provide sufficient 
evidence of benefit. Specifically in patients with well-differentiated NET, a considerably long 
overall survival and heterogeneity of survival prognostic factors make a survival endpoint 
unsuitable for an early read-out of treatment efficacy for a novel agent (Yao 2008). The study 
design as proposed is expected to provide initial evidence of benefit by showing an 
improvement in ORR, supported by duration of response, which based on clinical experience 
with PD-1 inhibitors, should serve as an appropriate surrogate to predict clinical benefit. A 
uniformly low ORR has been reported in well-differentiated NET from all tumor origins in 
patients receiving placebo or best supportive care in randomized studies (ranging from 0% to 
2%), (Table 1-1). In patients with advanced and progressive NETs, where available treatments 
have failed, an improvement in terms of ORR would be a relevant indicator of treatment 
efficacy. 
With regards to poorly-differentiated GEP-NEC, there are limited published results, mostly 
from retrospective studies reporting on small series of patients with advanced /metastatic
disease. For this reason, the analysis of the data from this group of patients intends to explore 
the antitumor activity of PDR001 in this population with a high unmet medical need. 
2.3
Rationale for dose and regimen selection
In study [CPDR001X2101], PDR001 single-agent was administered as an intravenous infusion 
over 30 minutes at doses ranging from 1 to 10 mg/kg on an every 2 weeks (Q2W) schedule or 
at 3 and 5 mg/kg every 4 weeks (Q4W) schedules. Approximately dose-proportional increase 
in exposure (C1D1 AUC0-336) was observed with doses from 1 to 10 mg/kg and no DLTs were 
observed. Accumulation of approximately 2.1-3.4-fold was observed with Q2W dosing and 1.6-
2.2-fold with Q4W dosing. Population PK analysis indicated that the changes in exposure due 
to patient weight differences are minimal across the anticipated weight range of 30 to 150 kg 
for the patient population. Therefore, a flat dosing scheme was selected. Two recommended 
phase II dosing regimens have been established: 300 mg Q3W and 400 mg Q4W flat dosing 
schedules. A flat dose of 400 mg Q4W or 300 mg Q3W is expected to achieve a mean steady-
state Ctrough value higher than the ex vivo EC50 for antigen-stimulated IL-2 production, a 
translational biomarker for PD-1 blockade (Patnaik et al, 2015). Based on the safety profile 
observed in study [CPDR001X2101] (Section 1.2) and the expected Ctrough values, 400 mg 
Q4W is expected to be a safe and efficacious dose.

Risks and benefits
PDR001 is a humanized IgG4 monoclonal antibody which belongs to a class of agents known 
as immune-checkpoint inhibitors specifically anti-PD-1/PD-L1. This class of compounds has 
demonstrated significant improvement in efficacy combined with a tolerable and manageable 
safety profile, thus supporting recent regulatory approvals in melanoma, non-small cell lung 
cancer, squamous cell carcinoma of the head and neck, bladder cancer, renal cancer and
Hodgkin’s lymphoma.
Immune-checkpoint inhibitors including anti-PD-1/PD-L1 may be associated with the 
occurrence of immune-mediated adverse events (irAE). In general, irAE can potentially involve 
every organ system but gastrointestinal (colitis), dermatologic, hepatic (hepatitis), pulmonary 
(pneumonitis), renal (nephritis) and endocrine toxicities (hypothyroidism, hyperthyroidism, 
diabetes, hypophysitis and hypopituitarism) are the most frequent and rarely CNS (encephalitis). 
These side effects are generally manageable but fatal events have been reported in some cases 
with checkpoint inhibitor compounds (Eggermont 2015; Larkin 2016; Hofmann 2016). 
Appropriate eligibility criteria as well as specific dose modification and stopping rules along 
with AE management guidelines (provided in Section 6.3.1), are included in this protocol. 
Recommended guidelines for prophylactic or supportive treatment for expected toxicities, 
including management of study-drug induced adverse events i.e., skin toxicity and diarrhea are 
provided in Section 6.3.1.2. The risks to patients in this trial may be minimized by compliance 
with the eligibility criteria and study procedures as well as, close clinical monitoring. There 
may be unforeseen risks with PDR001 which could be serious. Refer to preclinical toxicity and 
or clinical data found in the latest [Investigator’s Brochure].
For patients with unresectable locally advanced or metastatic non-functioning NETs 
progressing on or after currently available therapies, available treatment options are limited 
(Section 1.1). For this reason, PDR001 treatment may provide clinical benefit which will be 
measured as tumor shrinkage (ORR) and time-related parameters (including duration of 
response, PFS, and OS rates at 1 and 2 years). 
The efficacy endpoints will be assessed as per RECIST 1.1 (Appendix 1). Patients may continue 
treatment beyond disease progression by RECIST 1.1 and until disease progression by 
irRECIST if the criteria stipulated in Section 6.1.5.1 are met. This measure intends to minimize 
the risk of early treatment discontinuation for patients who are receiving immune- based 
treatment and experiencing clinical benefit and to allow enough time for the patient’s immune 
system to elicit an effective antitumor response, if it were to develop. 
Taking into consideration the safety profile observed so far, the unmet medical need in this 
population of patients with NET after treatment failure with available standard therapy and the 
measures implemented in the protocol to minimize the risks described above, the benefit-risk 
assessment is deemed acceptable to conduct this study in patients with NETs as part of the 
global clinical development of PDR001.

Study design
4.1
Description of study design
This is a phase II, single-arm, open-label, multi-center study in patients with

Well-differentiated, non-functional, grade 1 or 2, neuroendocrine tumors of pancreatic, GI 
or thoracic (including lung and thymus) origins and 

Poorly-differentiated GEP-NEC 
All patients must have progressed on or after the last treatment. (as described in Section 5.1).
A total of approximately 90 patients will be enrolled in the well-differentiated group, with 
approximately 30 patients enrolled in each cohort based on tumor origin. Approximately 20 
patients will be enrolled in the poorly-differentiated GEP-NEC group, for a total number of 
approximately 110 patients.
Treatment duration 
Patients will receive PDR001 at the dose of 400 mg Q4 weeks at flat dosing. Patients will 
continue to receive the assigned study treatment until disease progression by RECIST 1.1 or as 
per irRECIST (see below), unacceptable toxicity, start of a new anti-neoplastic therapy, 
withdrawal of consent, physician’s decision, lost to follow-up, death or the study is terminated 
by the sponsor.
Patients may continue study treatment beyond disease progression by RECIST 1.1 until disease 
progression as per irRECIST, as per BIRC (if criteria stipulated in Section 6.1.5.1 are fulfilled), 
unacceptable toxicity, start of new anti-neoplastic therapy, withdrawal of consent, physician’s 
decision, lost to follow-up, death, or the study is terminated by the sponsor. In case of 
continuation of study treatment beyond disease progression by RECIST 1.1, the patient will 
continue assessments as defined in Section 7. While the investigator is waiting for the results 
from the central imaging vendor confirming disease progression, the patient should continue on 
study treatment. However, during this time, the investigator should do whatever is medically 
necessary for his/her patient.

After the primary analysis cut-off date (10-Aug-2018):

Response assessments by BIRC will no longer be performed.

Patients, who are on treatment but have not yet progressed per local tumor response 
assessment, will continue study treatment until documentation of disease progression by 
RECIST 1.1 as per local investigator assessment, unacceptable toxicity, start of new anti-
neoplastic therapy, withdrawal of consent, physician’s decision, subject/guardian decision, 
lost to follow-up, death or the study is terminated by the sponsor. These patients will be 
permitted to continue study treatment beyond initial PD as per RECIST 1.1 until 
confirmed irPD per local assessment (until 2 consecutive irPDs), as described in Section 
6.1.5.1.

Patients who are on treatment beyond disease progression per local tumor response 
assessment (tumor assessment performed before the primary analysis cut-off date (10-
Aug-2018)) are allowed to continue study treatment as long as the patient derives clinical 
benefit from the treatment according to investigator’s best clinical judgement (e.g. no 
deterioration of performance status, no rapid increase in tumor burden, no clinical 
situation requiring alternative treatment), or until unacceptable toxicity, start of new anti-
neoplastic therapy, withdrawal of consent, lost to follow-up, death, or the study is 
terminated by the sponsor.


Safety follow-up: patients will be followed for safety at 30-Days, 60-Days, 90-Days, 120-
Days, and 150-Days after the last dose of PDR001 (Section 7.1.7)

Post-treatment efficacy follow-up: 

Before the primary analysis cut-off date (10-Aug-2018), patients who discontinue 
treatment for reasons other than irRECIST PD will have tumor assessments per Table 
7-1 until withdrawal of consent, death, lost to follow-up, or eventual irRECIST PD 
per BIRC even if new antineoplastic treatment (ANP) is started (Sections 7.1.8 and
Section 7.2.1)

After the primary analysis cut-off date (10-Aug-2018), post-treatment efficacy 
follow-up will be discontinued. Therefore, any patients, who are in post-treatment 
efficacy follow-up at the time of the primary analysis cut-off date, will enter the 
survival follow-up after completion of the safety follow-up. If clinically indicated, 
patients may continue to undergo tumor response assessments during the safety 
follow-up according to local or institutional standard of care; however these tumor 
response assessments will no longer be reported in the eCRF.

Survival follow-up: patients will be followed for survival every 3 months after the 
completion of safety or efficacy follow-up, whichever is last
For a diagram of the study flow, see Figure 4-2. Patients will undergo safety and efficacy 
assessments during screening, treatment, and follow-up as outlined in Table 7-1 visit evaluation 
schedule.
This study will use third-party vendors for central imaging, central laboratory, ePRO (e.g., 
electronic tablet devices to collect patient-reported outcomes (PRO) data), and eligibility 
checklist plus drug supply management via Interactive Response Technology (IRT). After the 
primary analysis cut-off date (10-Aug-2018) ePRO and central tumor response assessments will 
no longer be performed and/or collected.

4.2
Timing of interim analysis and design adaptations
A planned interim analysis (IA) will be conducted after approximately 30 patients in the well-
differentiated NET group have undergone the first 3 radiological assessments (expected around 
week 24) or have shown disease progression or have discontinued efficacy follow-up for any 
other reason. All available efficacy and safety data from well-differentiated NET and poorly 
differentiated GEP-NEC groups up to the cut-off date will be used for the IA and reviewed by 
the Steering Committee (see Section 10.7 for more details). It is expected that at the time of the 
interim analysis all patients from the poorly-differentiated GEP-NEC group have undergone at 
least 2 radiological assessments. The study will not be stopped at the interim analysis for 
efficacy reasons regardless of results and will be continued until mature data from all patients
become available.
4.3
Definition of end of study
Cut-off date for the primary analysis will be 1 year after Last Patient First Treatment (LPFT) in 
the initially enrolled well-differentiated NET group. This analysis will include data from 
patients with well-differentiated NET and poorly-differentiated GEP-NEC groups who were 
enrolled in the study. It is expected that at the time of this analysis all patients from the original 
poorly-differentiated GEP-NEC group will have at least 11 months follow-up. This analysis
will be summarized in the clinical study report (CSR).
If the analysis results are not conclusive or do not meet the pre-specified study criteria (refer to
Section 10.4), the treatment continuation for patients who are benefitting from PDR001

treatment will be assessed on a case-by-case basis in consultation with the sponsor. Patients 
who discontinue study treatment will complete the safety follow-up period. 
The end of study is defined as the earliest occurrence of one of the following :

All patients have discontinued treatment and completed safety follow-up period.

If another clinical study becomes available that can continue to provide treatment with 
PDR001 in this patient population and all ongoing patients are eligible to be transferred to 
that clinical study (and do not meet any discontinuation criteria from study 
CPDR001E2201). 

At the end of the study, every effort will be made to continue provision of investigational 
treatment outside this study through an alternative setting to patients who in the opinion of 
the Investigator are still deriving clinical benefit.
4.4
Early study termination 
If the study is stopped for safety reasons, recruitment will be terminated, and the treatment 
continuation of patients who are deriving benefit from PDR001 treatment will be assessed on a 
case-by-case basis in consultation with the sponsor. 
The study can be terminated at any time for any reason by Novartis. Should this be necessary, 
the patient should be seen as soon as possible and the same assessments should be performed 
as described in Section 7.1.6 for a discontinued or withdrawn patient. The investigator may be 
informed of additional procedures to be followed in order to ensure that adequate consideration 
is given to the protection of the patient’s interests. The investigator will be responsible for 
informing IRBs and/or ECs of the early termination of the trial.

22. Not able to understand and to comply with study instructions and requirements.
23. Pregnant or nursing (lactating) women confirmed by a positive hCG laboratory test within 
72 hours prior to initiating study treatment. Note: Low levels of hCG may also be 
considered a tumor marker, therefore if low hCG levels are detected, another blood sample 
at least 4 days later must be taken to assess the kinetics of the increase and transvaginal 
ultrasound must be performed to rule out pregnancy.
24. Women of child-bearing potential, defined as all women physiologically capable of 
becoming pregnant, unless they are using highly effective methods of contraception 
during dosing and for 150 days after stopping treatment with PDR001. Highly effective 
contraception methods include:
a. Total abstinence (when this is in line with the preferred and usual lifestyle of the 
patient). Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation 
methods) and withdrawal are not acceptable methods of contraception
b. Female sterilization (have had surgical bilateral oophorectomy with or without 
hysterectomy), total hysterectomy, or tubal ligation at least six weeks before taking 
study treatment. In case of oophorectomy alone, only when the reproductive status of 
the woman has been confirmed by follow up hormone level assessment
c. Male sterilization (at least 6 months prior to screening). The vasectomized male 
partner should be the sole partner for that patient
d. Use of oral, injected or implanted hormonal methods of contraception or placement of 
an intrauterine device (IUD) or intrauterine system (IUS), or other forms of hormonal 
contraception that have comparable efficacy (failure rate <1%), for example hormone 
vaginal ring or transdermal hormone contraception 
Note: In case of use of oral contraception women should have been stable on the same 
pill for a minimum of 3 months before taking study treatment. 
Women are considered post-menopausal and not of child bearing potential if they have had 12 
months of natural (spontaneous) amenorrhea with an appropriate clinical profile (i.e. age 
appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with
or without hysterectomy), total hysterectomy, or tubal ligation at least six weeks prior to 
enrollment. In the case of oophorectomy alone, a woman is considered not of child bearing 
potential only when her reproductive status has been confirmed by follow up hormone level 
assessment.
26. Known history or current interstitial lung disease or non-infections pneumonitis.
27. Use of somatostatin analogs or any other medications administered to control active 
symptoms related to carcinoid syndrome during the last 3 months prior to start of study 
treatment.

Treatment
6.1
Study treatment
For this study, the investigational drug is PDR001. The study treatment is defined as PDR001. 
PDR001 is supplied as PDR001 100 mg powder for solution for infusion. PDR001 will be 
diluted in dextrose 5% in water (D5W). Due to incompatibility, 0.9% sodium chloride solution 
must not be used. PDR001 will be administered at a dose of 400 mg every 4 weeks given as a 
30 minute infusion. 
PDR001 infusion must take place in a facility with appropriate resuscitation equipment 
available at the bedside and a physician readily available during the period of drug 
administration.
All dosages prescribed and administered to patients and all dose interruptions and changes 
during the study must be recorded on the Dosage Administration Record (DAR) eCRF page.

PDR001 will be administered via intravenous infusion over 30 minutes (up to 2 hours, if 
clinically indicated) once every 4 weeks (+/- 7 days window). PDR001 will be administered on 
Day 1 of every cycle. Each cycle is 28 days. The actual date of Cycle Day 1 will be used to 
project the dates of future cycles. The dose may be interrupted for up to 12 weeks. The safety 
assessments (as per Table 7-1 and Section 7.2.2) should be performed according to the actual 
day of infusion.
6.1.2
Ancillary treatments 
Patients should not receive pre-medication to prevent infusion reaction before the first infusion 
of PDR001 as a way to determine if pre-medication is necessary. If a patient experiences an 
infusion reaction, he/she may receive pre-medication prior to subsequent dosing days. The pre-
medication should be chosen per institutional standard of care at the discretion of the treating 
physician.
Acute allergic reactions should be treated as needed per institutional standard of care. In the 
event of anaphylactic/anaphylactoid reactions, this includes any therapy necessary to restore 
normal cardiopulmonary status. If a patient experiences a severe anaphylactic/anaphylactoid 
reaction, the infusion should be discontinued immediately. The patient may only resume study 
treatment following discussion with Novartis.
Patients should be treated in a facility equipped for cardiopulmonary resuscitation. Appropriate 
resuscitation equipment should be available at the bedside and a physician readily available.
Guidelines on management of PDR001 infusion reactions are provided in Section 6.3.1.2.

Treatment duration
All patients will begin treatment on Cycle 1 Day 1. 
Prior to the primary analysis cut-off date (10-Aug-2018), patients will continue study treatment 
until disease progression per RECIST 1.1 or irRECIST (see below), as per BIRC, unacceptable 
toxicity, start of new anti-neoplastic therapy, withdrawal of consent, physician’s decision, 
subject/guardian decision, lost to follow-up, death or the study is terminated by the sponsor. 
While the investigator is waiting for the results from the central imaging vendor to confirm
disease progression, the patient should continue on study treatment. However, during this time, 
the investigator should do whatever is medically necessary for his/her patient.
After the primary analysis cut-off date (10-Aug-2018):

Response assessments by BIRC will no longer be performed.

Patients, who are on treatment but have not yet progressed per local tumor response 
assessment, will continue study treatment until documentation of disease progression by 
RECIST 1.1 as per local investigator assessment, unacceptable toxicity, start of new anti-
neoplastic therapy, withdrawal of consent, physician’s decision, subject/guardian decision, 
lost to follow-up, death or the study is terminated by the sponsor. These patients will be 
permitted to continue study treatment beyond initial PD as per RECIST 1.1 until 
confirmed irPD per local assessment (until 2 consecutive irPDs), as described in Section 
6.1.5.1.

Patients, who are on treatment beyond disease progression per local tumor response 
assessment (tumor assessment performed before the primary analysis cut-off date [10-
Aug-2018]), are allowed to continue study treatment as long as the patient derives clinical 
benefit from the treatment according to investigator’s best clinical judgement (e.g. no 
deterioration of performance status, no rapid increase in tumor burden, no clinical 
situation requiring alternative treatment), or until unacceptable toxicity, start of new anti-
neoplastic therapy, withdrawal of consent, lost to follow-up, death, or the study is 
terminated by the sponsor. 
6.1.5.1
Treatment beyond disease progression
Emerging clinical data indicate that patients may derive benefit from continuing study treatment 
despite initial evidence of disease progression (Section 2.5).

Prior to the primary analysis cut-off date (10-Aug-2018), patients treated with PDR001 will be 
permitted to continue study treatment beyond initial disease progression as per RECIST 1.1 
until disease progression per irRECIST, as per BIRC, unacceptable toxicity, start of new anti-
neoplastic therapy provided they meet all of the following criteria:

Absence of disease progression per irRECIST, as per BIRC, confirmed by 2 consecutive 
assessments

The continuation of treatment beyond progression will not delay an imminent intervention 
to prevent serious complications of disease progression

Patients exhibit adequate tolerance to study treatment

Patient performance status is stable 
Patients who meet the above criteria should continue study treatment beyond initial disease 
progression per RECIST 1.1 and continue all study procedures as outlined in Section 7. The 
reasons for the patient continuing treatment will be documented in the eCRF.  
In case of clinical deterioration or suspicion of disease progression, a follow-up imaging
assessment should be performed promptly rather than waiting for the next scheduled assessment. 
Treatment with PDR001 in patients who are no longer deriving clinical benefit or have disease 
progression as per irRECIST by BIRC confirmed by 2 consecutive assessments must be 
discontinued.
After the primary analysis cut-off date (10-Aug-2018):

Dose modifications
6.3.1
Dose modification and dose interruption
For patients who do not tolerate the protocol-specified dosing schedule, dose interruptions are 
mandated in order to allow patients to continue study treatment. Dose interruption for PDR001 
includes delaying or withholding treatment for any reason as well as interrupting treatment 
during an infusion.
The following sections address specific instructions for mandatory dose modifications and 
recommended management of adverse events considered suspected to be related to PDR001.
6.3.1.1
Dose modification and dose interruption for PDR001
General dose modification instructions:
No changes in the dose of PDR001 are allowed.  
AEs are to be graded according to NCI-CTCAE v4.03 (ctep.cancer.gov). All dose interruptions 
and the reasons for dose interruption must be documented in the eCRF.  
Treatment of patients with AEs suspected to be related to PDR001 including those of potential 
immune-mediated etiology (irAE) (see definition in Section 6.3.1.2.1) must be permanently 
discontinued if the following occurs within 12 weeks:

AEs do not recover to ≤ grade 1 or baseline 

The dose of steroids (for the management of irAEs) is > 10 mg/day prednisone or 
equivalent (or as indicated in the tables below)
The 12 weeks’ period starts from the time an irAE reaches a severity grade that requires 
PDR001 interruption.
6.3.1.2
Dose Modification requirements for potential immune- mediated 
adverse events 
6.3.1.2.1 Identification of and management requirements for AEs of potential 
immune-mediated etiology (irAE)
Adverse events of special interest (AESI) include AEs of a potential immune-mediated etiology 
(irAE) that are associated with PDR001 treatment. An irAE may be experienced by patients 
treated with PDR001 due to its mechanism of action; it is predicted based on the reported prior 
experience with other immunotherapies that have a similar mechanism of action. Investigators 

Novartis
Confidential
Page 49
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
must be vigilant and must carefully identify AEs that may be suggestive of potential irAEs as 
their appearance may be sub-clinical and early diagnosis is critical for its adequate management 
and resolution. 
irAEs are typically low grade and self-limited, often occurring after multiple doses, and most 
frequently involving the GI tract (diarrhea/colitis), skin (rashes), liver (hepatitis), lung 
(pneumonitis), kidneys (nephritis) and endocrine systems (a variety of endocrinopathies) and 
rarely CNS (encephalitis). Serological, immunological and histological assessments should be 
performed as deemed appropriate by the investigator, to verify the potential immune-related 
nature of the AE, and exclude a neoplastic, infectious or metabolic origin of the AE.
Severe grade or persistent lower grade irAEs typically require interrupting or permanently 
discontinuing treatment and administration of systemic steroids or other non-corticosteroid 
immunosuppressive medication when systemic steroids are not effective. Early recognition of 
irAEs and initiation of treatment are critical to reduce the risk of complications, since the 
majority of irAEs are reversible with the use of steroids and other immune suppressants. 
Patients should be instructed to return to the study site as soon as possible (instead of waiting 
for their next scheduled visit) if they experience symptoms consistent with an irAE. Patients 
who experience a new or worsening irAE should be contacted and/or evaluated by the study 
site more frequently. 
Based on literature from compounds with similar mechanism of action of PDR001, instructions 
have been developed regarding how to identify, assess severity and manage irAEs that may 
occur in patients receiving PDR001. The dose modification requirements and AE management 
guidelines for the potential irAEs are provided in the following tables: diarrhea/colitis (Table 
6-2), hepatitis (liver laboratory alterations) (Table 6-3), skin (rash) (Table 6-4), nephritis (Table 
6-5), pneumonitis (Table 6-6), encephalitis (Table 6-7), endocrinopathies (Table 6-8), PDR001-
infusion reaction & cytokine release syndrome (Table 6-9), and other potential immune-related 
AEs of special interest (Table 6-10). Any grade 4 irAE must result in permanent discontinuation 
of PDR001.  
Under the category of OTHERS (Table 6-11 and Table 6-12) are included several irAE of 
interest that must be managed specifically and for which not specific guidance are provided in 
the table below. OTHERS include (but is not restricted to) the following events: autoimmune 
neuropathy, demyelinating polyneuropathy, Guillain-Barre, myasthenia Gravis-like syndrome, 
non-infectious myocarditis, non-infectious pericarditis, pancreatitis and rapid onset of grade 3 
fatigue in the absence of disease progression.
Patients receiving PDR001 may experience irAEs other than those listed in this document;
therefore, all AEs of unknown etiology associated with drug exposure should be evaluated to 
determine if they are possibly immune-related. In cases where the specific irAEs are not listed 
in the tables below, the investigator should follow the dose modification requirements in 
Section 6.3.1.3 which details the measures to be taken for suspected (they could be potentially 
immune-related or non-immune-related) AEs. Investigators are encouraged to contact the 
sponsor as needed to discuss cases that warrant separate discussion outside of the scope of the 
current instructions.

The dosing modification requirements are mandatory; however, the AE management guidelines 
are recommendations and can be modified according to local practices. The management of 
irAEs may include initiation of antibiotics for prophylaxis against opportunistic infections.

● Diarrhea > 48hrs: loperamide 2 mg every two hours; 
maximum 16 mg/day. Consider other second-line 
therapies for diarrhea (e.g: (octreotide, oral 
diphenoxylate) and oral antibiotics
● If Grade 2 and no improvement in 5 days may require 
oral steroids
● If Grade 2 diarrhea persists >1 week consider GI 
consultation and endoscopy to evaluate for colitis.
● If Grade 2 persists for 5 days and worsening of 
symptoms or diffuse ulcerations and bleeding seen on 
endoscopy, commence steroids at a dose of 0.5-
1mg/kg per day of prednisolone (or IV equivalent) and 
continue until symptoms improve to Grade 1. If no 
improvement occurs, manage as per Grade 3. Steroids 
can be tapered as per Section 6.3.1.2.2.
● Sigmoidoscopy and biopsy can be considered and 
may assist in determining the duration of steroid taper 
based on the evidence of macroscopic and microscopic 
inflammation.
● Continue PDR001 
treatment
● If diarrhea is Grade 2, 
despite loperamide at 2 mg 
every two hours for > 48hrs:
● Interrupt PDR001 until 
diarrhea recovers to Grade 
≤1 and then restart PDR001 
treatment at the same dose 
and schedule.

indicated; peritoneal 
signs
● Clinical evaluation and hospitalization mandatory; rule 
out bowel perforation and intravenous hydration.
● Consider consultation with gastroenterologist and 
confirmation biopsy with endoscopy.
● In addition to symptomatic treatment (diet, hydration, 
loperamide, antibiotics if indicated); initiate immediate 
treatment with intravenous steroids 
(methylprednisolone 125 mg) followed by high dose 
oral steroids (prednisone 1 to 2 mg/kg once per day or 
dexamethasone 4 mg every 4 hours) is recommended. 
● When symptoms improve to ≤Grade 1, steroid taper 
should be done as per Section 6.3.1.2.2.
● Taper over 6 to 8 weeks in patients with diffuse and 
severe ulceration and/or bleeding.
● If no improvement in 2-3 days: consider initiating 
infliximab 5mg/kg and continue steroids. (Infliximab is 
contraindicated in patients with sepsis or a perforation). 
Upon symptomatic relief initiate a prolonged steroid 
taper over 45 to 60 days. 
● If symptoms worsen during steroid reduction, initiate a 
re-tapering of steroids starting at a higher dose of 80 or 
100 mg followed by a more prolonged taper and 
administer infliximab.
1st occurrence: 
● Interrupt PDR001 until 
diarrhea/colitis recovers to 
Grade ≤1 or baseline
● Once recovered restart 
PDR001 treatment at the 
same dose and schedule 
and after appropriate steroid 
tapering (if initiated).
● AE resolution to ≤ Grade 1 
or baseline must occur within 
a period of 12 weeks since a

6.3.3
Follow-up for toxicities
Serologic, histologic (tumor sample) and immunological assessments should be performed as 
deemed appropriate by the Investigator to verify the immune-related nature of the AE and to 
exclude alternative explanations. Recommendations (Section 6.3) have been developed to assist 
investigators in assessing and managing the most frequently occurring irAEs.
Patients whose treatment is interrupted or permanently discontinued due to an irAE, AE or 
clinically significant laboratory value, must be followed-up at least once a week (or more 
frequently if required by institutional practices, or if clinically indicated) for 30 days, and 
subsequently at approximately 30-day intervals (or more frequently if required by institutional 
practices, or if clinically indicated), until resolution or stabilization of the event, whichever 
comes first. Appropriate clinical experts should be consulted as deemed necessary.
If an AE is suspected to be immune-related, the relevant immunological assessments (e.g. 
rheumatoid factor, anti-DNA Ab, etc.) should be performed. If cytokine release syndrome is 
suspected, the assessments outlined in Section 7.2.6.6.5 must be performed.
All patients must be followed-up for AEs and SAEs for 150 days following the last dose of 
PDR001. However, if the patient begins post-treatment antineoplastic medication during the 
period between the 30-Day safety follow-up and 150-Day safety follow-up, the collection of 
new SAEs and AEs unrelated to study medication will stop, and thereafter only suspected SAEs 
and suspected AEs will continue to be collected to Day 150. If SAEs suspected to be related to 
study medication occur beyond Day 150, information should also be collected. Section 6.3.3.1
outline the follow-up evaluations recommended for selected toxicities.
6.3.3.1
Follow up on potential drug-induced liver injury (DILI) cases
Patients with transaminase increase combined with TBIL increase may be indicative of 
potential DILI, and should be considered as clinically important events. 
The threshold for potential DILI may depend on the patient’s baseline AST/ALT and TBIL 
value; patients meeting any of the following criteria will require further follow-up as outlined 
below:

For patients with normal ALT and AST and TBIL value at baseline: AST or ALT > 3.0 x 
ULN combined with TBIL > 2.0 x ULN 

For patients with elevated AST or ALT or TBIL value at baseline: [AST or ALT > 2 x 
baseline AND > 3.0 x ULN] OR [AST or ALT > 8.0 x ULN], combined with [TBIL > 2 x 
baseline AND > 2.0 x ULN]
Medical review needs to ensure that liver test elevations are not caused by cholestasis, defined 
as ALP elevation > 2.0 x ULN with R value < 2 in patients without bone metastasis, or elevation 
of ALP liver fraction in patients with bone metastasis.

Novartis
Confidential
Page 61
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
Note: (The R value is calculated by dividing the ALT by the ALP, using multiples of the ULN 
for both values. It denotes whether the relative pattern of ALT and/or ALP elevation is due to 
cholestatic (R ≤ 2), hepatocellular (R ≥ 5), or mixed (R >2 and < 5) liver injury).
In the absence of cholestasis, these patients should be immediately discontinued from study 
drug treatment, and repeat LFT testing as soon as possible, preferably within 48 hours from the 
awareness of the abnormal results. The evaluation should include laboratory tests, detailed 
history, physical assessment and the possibility of liver metastasis or new liver lesions, 
obstructions/compressions, etc. 
1. Laboratory tests should include ALT, AST, albumin, creatine kinase, total bilirubin, direct 
and indirect bilirubin, GGT, prothrombin time (PT)/INR and alkaline phosphatase. 
2 . A detailed history, including relevant information, such as review of ethanol, concomitant 
medications, herbal remedies, supplement consumption, history of any pre-existing liver 
conditions or risk factors, should be collected. 
3. Further testing for acute hepatitis A, B, C or E infection and liver imaging (e.g. biliary 
tract) may be warranted. 
4. Obtain PK sample, as close as possible to last dose of study drug, if PK analysis is 
performed in the study. 
5. Additional testing for other hepatotropic viral infection (CMV, EBV or HSV), 
autoimmune hepatitis or liver biopsy may be considered as clinically indicated or after 
consultation with specialist/hepatologist. 
All cases confirmed on repeat testing meeting the laboratory criteria defined above, with no 
other alternative cause for LFT abnormalities identified should be considered as “medically 
significant”, thus, met the definition of SAE (Section 8.2.1) and reported as SAE using the term 
“potential drug-induced liver injury”. All events should be followed up with the outcome clearly 
documented.

Concomitant medications 
6.4.1
Permitted concomitant therapy
In general, concomitant medications and therapies deemed necessary for the supportive care 
(e.g. such as anti-emetics, anti-diarrhea) and safety of the patient are allowed except those 
prohibited in Section 6.4.3. The following list includes permitted concomitant therapies:

Medications to prevent or treat nausea or vomiting.

Anti-diarrheal medications (e.g., loperamide) for patients who develop diarrhea.

Pain medication to allow the patient to be as comfortable as possible.

Localized radiotherapy and treatment with bisphosphonates for pre-existing, painful 
bone/liver metastases is permitted. The radiotherapy must be listed on the CRF.

Immunosuppressive agents to treat suspected irAEs.

Nutritional support or appetite stimulants (e.g. megestrol).

Oxygen therapy and blood products or transfusions.

Limited-field palliative radiotherapy may be allowed as concomitant therapy. Such local 
therapies administered during the study treatment must be listed on the CRF.


The patient must be told to notify the investigational site about any new medications 
he/she takes after the start of the study drug. All medications (other than study drug) and 
significant non-drug therapies (including physical therapy, herbal/natural medications and 
blood transfusions) administered during the study must be listed on the Concomitant 
Medications.
6.4.2
Permitted concomitant therapy requiring caution and/or action 
If a patient is using erythropoiesis stimulating agents (ESAs) prior to enrollment (at least 2 
weeks before start of study treatment), he/she may continue the treatment.
Anticoagulation and anti-aggregation agents are permitted if the patients are already at stable 
doses for > 2 weeks at time of first dose and International Normalized Ratio (INR) should be 
monitored as clinically indicated per investigator’s discretion. However, ongoing anticoagulant 
therapy should be temporarily discontinued to allow tumor sample according to the institutional 
guidelines.
6.4.3
Prohibited concomitant therapy
During the course of the study, patients must not receive other additional investigational drugs, 
devices, chemotherapy, or any other therapies that may be active against cancer or modulate 
the immune responses. However, limited-field palliative radiotherapy may be allowed as 
concomitant therapy. Such local therapies administered during the study treatment must be 
entered into the CRF. Additionally, no other therapeutic monoclonal antibodies and no 
immunosuppressive medication may be administered while on this study unless given for the 
management of immune toxicity. 
The use of somatostatin analogs or any other medications administered to control active 
symptoms related to carcinoid syndrome is not permitted during the study unless there is a 
change to functional status (Section 6.4.4.1).
The use of systemic steroid therapy and other immunosuppressive drugs is not allowed except 
for the treatment of infusion reaction, irAEs, and for prophylaxis against imaging contrast dye 
allergy or replacement-dose steroids in the setting of adrenal insufficiency (providing this is < 
10 mg/day prednisone or equivalent), or transient exacerbations of other underlying diseases 
such as COPD requiring treatment for ≤3 weeks. If systemic corticosteroids are required for 
the control of infusion reactions or irAEs, it must be tapered and be at non-immunosuppressive 
doses (< 10 mg/day of prednisone or equivalent) before the next administration of study 
treatment. If the dose of prednisone or equivalent cannot be reduced to less than 10 mg/day 
before the administration of next dose of study treatment then PDR001 must be discontinued.
The use of live vaccines is not allowed through the whole duration of the study. Inactivated 
vaccines are allowed.
There are no prohibited therapies during the post-treatment follow-up period.

Patient numbering, treatment assignment 
6.5.1
Patient numbering
Each patient is identified in the study by a Subject Number (Subject No.), that is assigned when 
the patient is first enrolled for screening and is retained as the primary identifier for the patient 
throughout his/her entire participation in the trial. The Subject No. consists of the Center 
Number (Center No.) (as assigned by Novartis to the investigative site) with a sequential patient 
number suffixed to it, so that each patient is numbered uniquely across the entire database. Upon 
signing the informed consent form, the patient is assigned to the next sequential Subject No. 
available to the investigator through the Oracle Clinical RDC interface.
The investigator or designated staff will contact the IRT and provide the requested identifying 
information for the patient to register them into the IRT. Once assigned, the Subject No. must 
not be reused for any other patient and the Subject No. for that individual must not be changed, 
even if the patient is re-screened. If the patient fails to start treatment for any reason, the reason 
will be entered into the Screening Disposition page.
IRT must be notified within 2 days that the patient was not treated as scheduled.
6.5.2
Medication number assignment 
All patients who fulfill all inclusion/exclusion criteria will be assigned to be treated with 
PDR001. No randomization will be performed in this study.
IRT will be used to assign a medication number for each PDR001 dose. The assignment of a 
patient to a particular cohort/group (pancreatic, GI, thoracic or GEP-NEC) will be coordinated 
and monitored by the sponsor.

Study treatment labels will comply with the legal requirements of each country and will include 
storage conditions, a unique medication number (corresponding to study treatment and strength). 
Responsible site personnel will identify the study treatment package(s) to dispense by the 
medication number(s) assigned by IRT to the patient. Site personnel will add the patient number 
on the label. If the label has 2-parts (base plus tear-off label), immediately before dispensing 
the package to the patient, site personnel will detach the outer part of the label from the package 
and affix it to the patient’s source document.
6.6.2
Drug supply and storage
Study treatment must be received by designated personnel at the study site, handled and stored 
safely and properly, and kept in a secured location to which only the investigator and designated

Visit schedule and assessments
7.1
Study flow and visit schedule
Table 7-1 lists all of the assessments and indicates with an “X”, when the visits are performed.
All data obtained from these assessments must be supported in the patient’s source 
documentation. The table indicates which assessments produce data to be entered into the 
database (D) or remain in source documents only (S) (“Category” column).
Table 7-1 also lists all changes in assessments after cut-off date of primary analysis (10-Aug-
2018).
No paper CRF will be used as a source document. 
PRO data will be captured on an ePRO tablet and is considered the source document.
Allowed visit windows are specified as follows:

7.1.1
Molecular pre-screening
Not applicable.
7.1.2
Screening
Patients with non-functional, well-differentiated grade 1 or 2, progressing NETs of pancreatic, 
GI or thoracic (lung or thymic) origin or patients with poorly-differentiated GEP-NEC will be 
screened for eligibility during a maximum period of 28 days (Day -28 to Day -1) immediately 
prior to starting PDR001 on study Day 1. During this time, the inclusion and exclusion criteria 
will be assessed, and all screening assessments will be performed according to Table 7-1. Tumor 
tissue must be sent to a central laboratory within the screening timeframe as per eligibility 
criteria defined in Section 5.
The tumor pathology report must be verified by the study investigator to confirm histology and 
grade of neuroendocrine tumor (including mitotic count, Ki-67 index, and absence or presence 
of necrosis, as applicable). Data from previous tumor assessments (i.e. imaging scans) 
performed as part of the patient’s routine care (prior to enrolling in the trial) must be considered 
to fulfill eligibility criteria #6 (Section 5.2). Patient eligibility will be checked once all screening 
procedures are completed. Results of all screening evaluations must be reviewed by the 
investigator prior to enrollment into the study, in order, to assure that all inclusion and exclusion 
criteria have been satisfied. Only laboratory results from the central laboratory can be used to 
determine patient eligibility. 
An eligibility review and confirmation will be embedded in the IRT system. Please refer to and 
comply with detailed guidelines in the IRT manual. The IRT system will confirm the inclusion 
of eligible patients.
If a patient completed all screening evaluations and did not meet eligibility criteria, the patient 
is a screen failure. However, the investigator may choose to re-screen the patient. If the 
investigator chooses to re-screen the patient, the patient must sign a new ICF. All required 
screening evaluations must be performed again during re-screening; all re-screening evaluations 
must be performed within 28 days prior to the start of study treatment. Re-screening is allowed 
once per patient as long as the patient was not assigned a medication number for first dose by 
IRT. In this case the “Patient number” assigned to the patient initially will be used, and the 
patient will be identified by this number throughout his/her entire participation to the study. All 
re-screened evaluations must meet the eligibility criteria for the patient to receive treatment. If 
the patient completes all re-screening evaluations and still do not meet eligibility criteria, the 
patient is a screen failure.
For central laboratory evaluations used to determine eligibility, a repeated evaluation within the 
screening window is permitted when initial results are out of the permitted range. In this case, 
the patient will not be required to sign another ICF, and the original patient ID number assigned 
by the investigator will be used. If the repeated laboratory result meets the criteria, that result 
may be used to determine eligibility. If the repeated laboratory result does not meet the criteria, 
the patient will be considered a screening failure.

Once the number of patients screened and enrolled is likely to ensure target enrollment in a 
cohort or the study, the sponsor will close the cohort or the study to further screening. In this 
situation, patients who screen failed will not be permitted to be re-screened.
7.1.2.1
Eligibility screening 
Once a patient is registered in the IRT for screening, patient eligibility will be checked after all 
screening procedures are completed. The eligibility checklist is embedded in the IRT system. 
Please refer and comply with detailed guidelines in the IRT manual.
7.1.2.2
Information to be collected on screening failures
A patient who signed an Informed Consent Form but did not start treatment for any reason will 
be considered a screen failure. 
The data from a screen failure patient will be entered on the Screening Phase Disposition Page.
The demographic information, informed consent, and Inclusion/Exclusion pages must also be 
completed for Screen Failure patients. No other data will be entered into the clinical database 
for screen failures patients, unless the patient experienced a Serious Adverse Event during the 
Screening Phase (see Section 8 for SAE reporting details).
7.1.2.3
Patient demographics and other baseline characteristics
Data will be collected on patient characteristics including:

Demographic information (age, sex, race, height and weight),  

Other background or relevant medical history, including HIV history, cancer, disease 
baseline characteristics (diagnosis, history, and extent of cancer, prior anticancer therapies 
including surgery and local therapies such as radiotherapy), and 

Any other assessments that are done for the purpose of determining eligibility for 
inclusion in the study (i.e., ECOG Performance Status, complete physical examination, 
vital signs, hematology, blood chemistries including coagulation studies and urinalysis, 
pregnancy test only required for women of child-bearing potential, tumor imaging 
assessments, ECG, etc.).
All medications and significant non-drug therapies taken within 30 days prior to start of study 
treatment must be recorded on the Concomitant medication eCRF page and updated on a 
continual basis if there are any new changes to the medications.
Tumor imaging assessments will be performed for screening purposes and for determination of
patient eligibility. Results of scans (as described in Table 7-2) performed within 28 days prior 
to start of study treatment will also be used as baseline values, except for whole body bone 
scans (if applicable, for suspected or known bone metastases), which can be performed within 
6 weeks of start of study treatment. Chest, abdomen, and pelvis CT or MRI scans and brain CT 
or MRI scan are required to be performed at screening. See Section 7.2.1 Efficacy assessments 
for more details.
To determine eligibility, measurable and non-measurable lesions must be assessed. Target 
lesions must be identified prior to start of treatment. For definition of measurable and target 
lesions, please refer to Appendix 1.

(Section 4.1). Patients will visit the site on Day 1 of each cycle (1 cycle = 28 days) or more 
frequently, if medically indicated. For details on study procedures during treatment, please see 
Table 7-1 Visit evaluation schedule.  
7.1.5
Discontinuation of study treatment
Patients may voluntarily discontinue from the study treatment for any reason at any time. If a 
patient decides to discontinue from the study treatment, the investigator should make a 
reasonable effort (e.g. telephone, e-mail, letter) to understand the primary reason for this 
decision and record this information in the patient’s chart and on the appropriate CRF pages. 
They may be considered withdrawn if they state an intention to withdraw, fail to return for visits, 
or become lost to follow-up for any other reason.
The investigator may discontinue study treatment for a given patient if he/she believes that 
continuation would be detrimental to the patient’s well-being.
Patients may stop study treatment for any of the following reasons:

Adverse event(s) 

Progressive Disease

Protocol Deviation

Technical problems

Physician decision

Subject/guardian decision
Patients must stop study treatment for any of the following reasons:

Death

Pregnancy 

Study terminated by sponsor

Lost to follow-up
Patients who discontinue study treatment should not be considered withdrawn from the study. 
They should undergo an end of treatment visit and then enter the safety, efficacy, and survival 
follow-up periods. If they fail to return for these assessments for unknown reasons, every effort 
(e.g. telephone, email, and letter) should be made to contact them as specified in Section 7.1.10.
Prior to and after the primary analysis cut-off date (10-Aug-2018), in some circumstances 
patients may be allowed to continue to receive study treatment beyond disease progression as 
per RECIST 1.1 criteria (Section 6.1.5.1). These patients will continue assessments as outlined 
in Section 7, and will complete the EOT visit only after permanent discontinuation of study 
treatment.

Patients who discontinue treatment prior to the primary analysis cut-off date (10-Aug-2018) for 
reasons other than irRECIST PD will have tumor assessments per Table 7-1 until withdrawal 
of consent, death, lost to follow-up or eventual irRECIST PD per BIRC even if new post 
treatment ANP is started.
After the primary analysis cut-off date (10-Aug-2018),  post-treatment efficacy follow-up will
be discontinued. Therefore, for patients who discontinue study treatment for any reasons after
the primary analysis cut-off date, post treatment efficacy follow-up will not be performed and 
these patients will enter the safety follow-up. If clinically indicated, patients may continue to 
undergo tumor response assessments during the safety follow-up according to local or 
institutional standard of care; however these tumor response assessments will no longer be 
reported in the eCRF.
The investigator must also contact the IRT to register the patient’s discontinuation from study
treatment.

7.1.6
Withdrawal of consent
Patients may voluntarily withdraw consent to participate in the study for any reason at any time. 
Withdrawal of consent occurs only when a patient does not want to participate in the study 
anymore, and does not allow any further collection of personal data.
In this situation, the investigator should make a reasonable effort (e.g. telephone, e-mail, letter) 
to understand the primary reason for this patient’s decision to withdraw his/her consent and 
record this information.
Study treatment must be discontinued and no further assessments conducted, and the data that 
would have been collected at subsequent visits will be considered missing.
Further attempts to contact the patient are not allowed unless safety findings require 
communicating or follow up.
All efforts should be made to complete the assessments prior to study withdrawal. A final 
evaluation at the time of the subject’s study withdrawal should be made as detailed in the 
assessment table.
Novartis will continue to keep and use collected study information (including any data resulting 
from the analysis of a subject’s samples until their time of withdrawal) according to applicable 
law.
For US and Japan: All biological samples not yet analyzed at the time of withdrawal may still 
be used for further testing/analysis in accordance with the terms of this protocol and of the 
informed consent form.  
For EU and RoW: All biological samples not yet analyzed at the time of withdrawal will no 
longer be used, unless permitted by applicable law. They will be stored according to applicable 
legal requirements.

Follow up for safety evaluations
All patients must be followed for safety 150 days after the last dose of PDR001 (Appendix 3).
After the 30-Day on-site safety follow-up visit, patients will be followed (via telephone call or 
on-site visit if patient happens to be visiting the site) at 60, 90, 120 and 150 days after the last 
dose of PDR001. However, women of childbearing potential must return to the site for the 150-
Day safety follow-up visit, in order, to have a serum pregnancy test; for 60, 90, 120 days safety 
follow-up, women of childbearing potential will perform a urine pregnancy test at home.
All safety assessments should be completed as per Table 7-1. However, if the patient begins 
post treatment antineoplastic medication during the period between the 30-Day and 150-Day 
safety follow-up, the collection of new SAEs and AEs unrelated to study medication will stop,
and thereafter only suspected AEs and suspected SAEs will continue to be collected up to 150-
Day safety follow-up. Suspected SAEs will continue to be collected beyond the 150-Day safety
follow-up. Data collected should be added to the appropriate eCRF pages. 
There are no changes in safety evaluations after the primary analysis cut-off date. 
7.1.8
Follow-up for efficacy evaluations
Patients who discontinue treatment for reasons other than irRECIST PD will have tumor 
assessments per Table 7-1 until withdrawal of consent, death, lost to follow-up or eventual 
irRECIST PD per BIRC even if new post treatment ANP is started.
After the primary analysis cut-off date (10-Aug-2018),  post-treatment efficacy follow-up will 
be discontinued.  Therefore, for patients who discontinue study treatment for any reasons after 
the primary analysis cut-off date, post treatment efficacy follow-up will not be performed and 
these patients will enter the safety follow-up.  If clinically indicated, patients may continue to 
undergo tumor response assessments during the safety follow-up according to local or 
institutional standard of care; however, these tumor response assessments will no longer be 
reported in the eCRF.
7.1.9
Survival follow-up
Patients will enter the survival follow-up period once they complete the safety follow-up period 
or efficacy follow-up, whichever is last. Patients will then be contacted by telephone every 12 
weeks to follow-up on their survival status. Any new antineoplastic medications that have been 
started since the last contact date will also be collected during these phone calls.
7.1.10
Lost to follow-up
For patients whose status is unclear because they fail to appear for study visits without stating 
an intention to withdraw consent, the investigator should show "due diligence" (three 
documented attempts) by contacting the patient, family or family physician as agreed in the 
informed consent and by documenting in the source documents steps taken to contact the patient, 
e.g. dates of telephone calls, registered letters, etc. A patient should not be considered lost to 
follow-up until due diligence has been completed. Patients lost to follow up should be recorded 
as such on the appropriate Disposition CRF.

Assessment types
7.2.1
Efficacy assessments
Tumor response will be assessed locally and centrally according to the Novartis guideline 
version 3.2 (Appendix 1) based on RECIST 1.1 (Eisenhauer et al 2009) and irRECIST 
(Appendix 2). The imaging assessment collection plan is presented in Table 7-2. Details of the 
central review process will be described in the independent review charter.
Imaging data will be centrally collected and checked for quality by an imaging Contract 
Research Organization (CRO) designated by Novartis. The results of the central evaluations 
will be used for primary analysis purposes. The local investigator’s assessment will be used for 
treatment decision making as described in Section 7.2.4.
Information regarding prior interventions (e.g., radiotherapy), pre-existing radiographic 
findings that mimic metastatic disease at baseline/screening and prior interventions should be 
transmitted to the imaging CRO via the Baseline Clinical Form along with the screening images 
for review by the independent radiologist. Sites must ensure the data entered on the form is 
consistent with the data entered in the clinical database.
Information regarding cytology results should be transmitted to the imaging CRO via the 
Cytology Form for all visits, when applicable, for review by the independent radiologist. Sites 
must ensure the data entered on the form is consistent with the data entered in the clinical 
database.
After primary analysis cut-off date (10-Aug-2018), medical imaging data and information 
regarding cytology results will no longer be collected and transmitted to the imaging Contract 
Research Organization (CRO) for central tumor response evaluation. Tumor response will be 
assessed locally by investigator, according to RECIST 1.1 (Appendix 1) and irRECIST 
(Appendix 2).

7.2.2
Baseline imaging assessments
Imaging assessments will be performed at screening within 28 days of start of treatment (Day -
28 to Day -1 prior to Cycle 1 Day 1).
Any imaging assessments already completed during the regular work-up of the patient within 
28 days prior to start of treatment, including before signing the main study ICF, can be 
considered as the baseline images for this study. Any imaging assessments obtained after start 
of study treatment cannot be considered baseline images. 
The following assessments are required at screening:

Computed Tomography (CT) with IV contrast or Magnetic Resonance Imaging (MRI) of 
Chest, abdomen and pelvis 

The preferred radiologic technique is CT with intravenous (IV) contrast. If a patient is 
known to have a contraindication to CT contrast or develops a contraindication during 
the trial, a non-contrast CT of the chest (MRI is not recommended due to respiratory 
artifacts) plus a contrast-enhanced MRI (if possible) of the abdomen and pelvis 
should be performed

Brain CT with IV contrast or MRI scan

Novartis
Confidential
Page 84
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201

If brain lesions are documented at baseline, scans need to be continued following the 
same schedule as CT/MRI of chest, abdomen and pelvis. The same methodology as 
used at screening should be used. Contrast enhanced brain MRI is preferred.  
However, if MRI contrast is contraindicated, then MRI without contrast or CT 
with/without contrast is acceptable.

A whole body bone scan according to institutional guidelines [e.g. Tc-99 bone scan, whole 
body bone MRI, Fluorodeoxyglucose positron emission tomography (FDG-PET) or 
sodium fluoride positron emission tomography (NaF PET)], if clinically indicated.

Whole body bone scans is not required for any timepoint, unless clinically indicated. 
It will not be the routinely used tumor imaging to monitor the response to the therapy.  

If skeletal lesions are documented on the whole body bone scan at baseline, localized bone 
CT, MRI or x-ray will be performed to follow up these lesions with the same schedule 
used for the tumor assessment by CT/MRI as described in Table 7-2. 

CT or MRI of other metastatic sites not captured by any of the above listed images (e.g., 
neck), if clinically indicated.

If additional sites of disease are documented at screening, scans need to be continued 
following the same schedule as CT/MRI of chest, abdomen and pelvis. The same 
methodology as at screening should be used.

Chest x-rays and ultrasound must not be used to measure tumor lesions.
Any potentially measurable lesion that has been previously treated with radiotherapy should be 
considered as a non-measurable lesion. However, if a lesion previously treated with 
radiotherapy has clearly progressed since the radiotherapy, it can be considered as a measurable 
lesion.
7.2.3
Post-baseline imaging assessments
Imaging assessments as described in Table 7-2 should be performed using the same imaging 
modality used at baseline, irrespective of study treatment interruption or actual dosing (see 
Table 7-1). 
Prior to the primary analysis cut-off date (10-Aug-2018), imaging assessments for response 
evaluation will be performed every 8 weeks (+/- 7 days) until Cycle 13, and every 12 weeks 
(+/- 7 days) thereafter until disease progression per RECIST 1.1 or irRECIST per BIRC, death, 
lost to follow-up or withdrawal of consent. Imaging assessments should be scheduled using the 
date of first dose (Cycle 1 Day 1) as the reference date (not the date of the previous tumor 
assessment), and should be respected regardless of whether treatment with study treatment is 
temporarily withheld or unscheduled assessments performed. 
Additional imaging assessments may be performed at any time during the study at the 
investigator’s discretion to support the efficacy evaluations for a patient, as necessary. Clinical 
suspicion of disease progression at any time requires a physical examination and imaging 
assessments to be performed promptly rather than waiting for the next scheduled imaging 
assessment.
Each lesion that is measured at baseline must be measured by the same method (either same 
imaging method or by photography, including a metric ruler) and when possible, the same local 

Novartis

Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
radiologist/physician throughout the study so that the comparison is consistent. If an off-
schedule imaging assessment is performed because progression is suspected, subsequent 
imaging assessments should be performed in accordance with the original imaging schedule.
Combined PET/CT may be used only if the CT is of similar diagnostic quality as a CT 
performed without PET, including the utilization of IV contrast media. At the discretion of the 
Investigators, FDG-PET scans may be performed to document progressive disease per RECIST 
1.1 (Appendix 1) or per irRECIST (Appendix 2).
All study imaging (including any off-schedule imaging studies) should be submitted to the 
designated imaging CRO for quality control and central review. 
After the primary analysis cut-off date (10-Aug-2018):

For patients on study treatment, imaging assessments will be scheduled according to local 
or institutional standard of care, as clinically indicated, and will continue until study 
treatment discontinuation.

Imaging data will no longer be centrally collected and transmitted to the imaging CRO.
Tumor response will be assessed locally according to RECIST 1.1 (Appendix 1) and 
irRECIST (Appendix 2).

Clinical suspicion of disease progression at any time requires a physical examination and 
imaging assessments to be performed promptly rather than waiting for the next planned
imaging assessment.
7.2.4
Timepoints at which progression is determined locally
All patients who have disease progression per RECIST 1.1 or disease progression per irRECIST 
determined by the local investigator require an expedited central review. Rapid image 
transmission to the imaging CRO may be accomplished by transferring the images 
electronically (e.g., via the Internet).
In all instances, the process at the imaging CRO will ensure that the central reviewers remain 
blinded to the results of the local assessment and the expedited nature of the review. The 
investigator seeking an expedited review must indicate this request to the imaging CRO on a 
designated form or by alternative means. For expedited requests, the scans will undergo 
expedited central review (within 5 business days from the time of image receipt at the imaging 
CRO and once all applicable queries are resolved) and the results of the central review will be 
communicated to the site. While the investigator is waiting for the results from the central 
imaging CRO confirming disease progression, the patient should continue on study treatment. 
However, during this time, the investigator should do whatever is medically necessary for 
his/her patient.
If the central review determines disease progression as per RECIST 1.1 (and the patient does 
not meet the criteria in Section 6.1.5.1) or disease progression per irRECIST, then the patient 
will discontinue study treatment and subsequent tumor assessments are only required if the 
patient has not met the criteria for disease progression per irRECIST as per the central imaging 
vendor. 
If the central review does not determine disease progression as per RECIST 1.1 or irRECIST, 
or the central reviewer determines disease progression as per RECIST 1.1, but the patient meets 

Novartis
Confidential
Page 86
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
the criteria in Section 6.1.5.1 to continue treatment, the patient should continue receiving the 
study treatment unless there is a medical need (i.e., rapid progression or clinical deterioration) 
for an immediate change in therapy. After the central reviewer determines disease progression 
per RECIST 1.1, an expedited review will be required only in case of disease progression 
determined locally per irRECIST at following assessments.
Patients will continue to have imaging performed as per protocol (Table 7-1) until the central 
review determines disease progression per irRECIST.
The imaging vendor will ensure that the central reviewers involved are blinded to the expedited 
status of the reading.
In summary, for expedited timepoints (assessed as PD by RECIST 1.1 or irRECIST by local):
Rapid image transmission to the central imaging CRO may be accomplished by uploading all 
digital images acquired by the Investigator in a secured website, while preserving the blinded 
status of the images.

If central radiology determines PD as per RECIST 1.1, or PD per irRECIST , the study 
site will be informed. This patient should then discontinue study drug unless the criteria 
are met to continue study treatment beyond disease progression per RECIST 1.1 as 
described in Section 6.1.5.1. An expedited review at future assessments will only be 
required if PD per irRECIST is determined by the local investigator.

If central radiology does not conclude PD as per RECIST 1.1 or PD as per irRECIST, the 
study site will be informed. As long as it is clinically acceptable, every effort should be 
made to continue the patient on study drug until PD as per irRECIST is determined by 
central review or for at least one subsequent radiological timepoint.
After the primary analysis cut-off date (10-Aug-2018):

Imaging data will no longer be centrally collected and transmitted to the imaging CRO. 
Patients who have disease progression per RECIST 1.1 or irRECIST as determined locally
do not require an expedited central review.

Tumor response will be assessed locally (i.e. by investigator) according to  RECIST 1.1 
(Appendix 1) and irRECIST (Appendix 2).
7.2.5
Timepoints without locally determined progression
All imaging timepoints without locally determined progression per RECIST 1.1 or PD as per 
irRECIST will be read on an ongoing, non-expedited basis as detailed in the imaging manual 
to be provided by the designated imaging CRO and independent review charter. Results of these 
readings will not be communicated to the sites.
After the primary analysis cut-off date (10-Aug-2018), imaging data will no longer be centrally 
collected and transmitted to the imaging CRO. 
7.2.6
Safety and tolerability assessments
Safety will be monitored by assessing physical examination, vital signs, weight, ECOG 
performance status, laboratory evaluations (including chemistry, hematology, hepatitis, 
coagulation, pregnancy, cytokines analysis), safety imaging (CT or MRI), and ECG as well as

collecting of the adverse events as well as collecting of the adverse events at every visit as 
indicated in Table 7-1. For details on AE collection and reporting, refer to Section 8.
7.2.6.1
Physical examination
A complete physical examination will include the examination of general appearance, skin, 
neck (including thyroid), eyes, ears, nose, throat, lungs, heart, abdomen, back, lymph nodes, 
extremities, vascular and neurological. If indicated based on medical history and/or symptoms, 
rectal, external genitalia, breast, and pelvic exams will be performed.
Significant findings that were present prior to the signing of informed consent must be included 
in the Medical History page on the patient’s CRF. Significant new findings that begin or worsen 
after informed consent must be recorded on the Adverse Event page of the patient’s CRF. 
7.2.6.2

Local laboratory assessments may be performed if medically indicated or when the treating 
physician cannot wait for central laboratory results for decision making. In this particular 
situation, the blood sample obtained at the same time point should be submitted to the central 
laboratory for analysis in parallel with local analysis.

Samples for cytokine panel at screening will be stored below -70°C.
7.2.6.6.6 Hepatitis marker
Hepatitis panels will be performed as per Table 7-4.
HBV-DNA serology (including HBV-DNA, HBsAg, HBsAb, HBcAb) and HCV RNA-PCR 
test will be performed at screening within 28 days prior to start of study treatment and as 
clinically indicated (hepatitis markers should be evaluated for precautionary safety monitoring 
of viral re-activation while on study treatment). 
During the screening period, patients must be screened for HBV and HCV (current or past 
history of infection). Careful medical history must be taken for all patients to look for risk 
factors (family history of HBV and HCV, intravenous drug abuse, unprotected sex, dialysis, 
blood transfusions, etc.), and any past or present HBV symptoms (e.g., jaundice, dark urine, 
light colored stools, right upper quadrant pain). 
Hepatitis B: 
At screening, all patients will be tested for: 

HBV-DNA level 

Hepatitis B surface antigen (HBsAg) 

Hepatitis B core antibody (HBcAb) 

Hepatitis B surface antibody (HBsAb) 
Hepatitis C: 
At screening, all patients will be tested for quantitative HCV RNA-PCR. 
After start of the study treatment and until 150-Day safety follow-up, testing for HBV and HCV 
should be performed if clinically indicated (for example: rule out viral causality in case of DILI).
7.2.6.6.7 CgA and NSE
The tumor markers, CgA and NSE, will be collected as described in Table 7-1.
7.2.6.6.8 Pregnancy and assessments of fertility
Serum and Urine pregnancy test will be performed as outlined in Table 7-5.
Women of child-bearing potential will have serum pregnancy tests within 72 hours prior to the 
first dose of study treatment. Monthly urine pregnancy tests will then be required to be 
performed on day 1 of every cycle beginning with Cycle 2, followed by serum pregnancy test 
at the End of Treatment visit, 30-Day and 150-Day Safety follow-up visit. During the follow-
up period after the 30-Day Safety Follow-up visit through the 120-Day follow-up telephone 
call, women of child-bearing potential will perform at-home urine pregnancy testing every 30 
days using kits provided. Women of child bearing potential must return to the site for the final 
pregnancy test (150-Day safety follow-up visit). For all pregnancy tests performed at home, the 
site personnel will follow-up with the patient via telephone call to collect the date and the test 
results and document the information in the patient’s source documents. For the 30-Day and

Pharmacokinetics and immunogenicity (IG) assessment
The exact date and clock times of drug administration PK and IG blood draw will be recorded 
on the appropriate eCRF.
Blood samples will be taken by either direct venipuncture or an indwelling cannula inserted in 
a forearm vein opposite to the arm used for infusion. 
A total of 5 mL of blood will be collected for PDR001 PK and IG analysis in serum (2 mL for 
PDR001 PK and 3 mL for IG).
For time points when PDR001 (mAb) PK and IG are to be measured, a single blood sample will 
be collected for both IG and PDR001 PK (Table 7-7). After clotting, the resulting serum will 
be separated in aliquots and will be stored frozen until analysis. 
Refer to the [Laboratory Manual] for detailed instructions for the collection, handling, and 
shipment of PK and IG samples.
If patients experience a SAE or an AE leading to the discontinuation of the study treatment, an 
unscheduled PK blood sample should be obtained as close as possible to the event occurrence. 
If patients experience suspected immunologically related AE such as infusion-related reaction, 
hypersensitivity, cytokine release syndrome and anaphylaxis, an unscheduled IG blood sample 
should be obtained as close as possible to the event occurrence. The date and time of the last 
dose and the time of PK blood draw should be recorded.

Patient reported outcomes
The European Organisation for Research and Treatment of Cancer’s core quality of life 
questionnaire (EORTC-QLQ-C30, version 3.0) and the EuroQoL 5-level instrument (EQ-5D-
5L, tablet version) will be used to evaluate patient-reported outcome measures of health-related 
quality-of-life, functioning, disease symptoms, treatment-related side effects, and global health 
status. The EORTC QLQ-C30 and EQ-5D-5L are recognized reliable and valid measures 
(Aaronson 1993, Rabin 2001) frequently used in clinical trials of patients with advanced or 
metastatic cancer. 
All patient-reported outcome (PRO) measures (e.g, EORTC QLQ-C30, EQ-5D-5L) will be 
administered before any study drug administrations at the visits indicated in Table 7-1 and Table 
7-9. Collections of PRO measures have a ±7 day window unless otherwise indicated.
All PRO data will be collected using an electronic tablet device and should be administered in 
the patient’s local language at the beginning of the study visit prior to any interaction with the 
study investigator including any tests, treatments or receipt of results from any tests to avoid 
biasing the patient’s perspective. Patients should be given sufficient space and time to complete 
all study questionnaires and all administered questionnaires should be reviewed for 
completeness. If missing responses are noted, patients should be encouraged to complete any 
missing responses. Attempts should be made to collect responses to all questionnaires for all 
patients, including data from the efficacy follow-up however, if patients refuse to complete 
questionnaires, this should be documented in study source records. Patient’s refusal to complete 
study questionnaires are not protocol deviations.
Completed questionnaires, including both responses to the questions and any unsolicited 
comments provided by the patient, must be reviewed and assessed by the investigator before 

Novartis

the clinical examination for responses which may indicate potential AEs or SAEs. This review 
should be documented in study source records.
If an AE or SAE is confirmed then the physician should record the event as instructed in Section 
8 of this protocol. Investigators should not encourage the patients to change responses reported 
in questionnaires.
After the primary analysis cut-off date (10-Aug-2018), patient-reported outcome 
questionnaires (EORTC QLQ-C30, EQ-5D-5L) will no longer be collected.

7.2.10.1 EORTC QLQ-C30 
The EORTC QLQ-C30 contains 30 items and is composed of both multi-item scales and single-
item measures. These include five functional scales (physical, role, emotional, cognitive and 
social functioning), three symptom scales (fatigue, nausea/vomiting, and pain), six single items 
(dyspnea, insomnia, appetite loss, constipation, diarrhea and financial impact) and a global 
health status/QoL scale (Aaronson et al 1993). 
All of the scales and single-item measures range in score from 0 to 100. A high scale score 
represents a higher response level. Thus a high score for a functional scale represents a high / 
healthy level of functioning; a high score for the global health status / QoL represents a high 
QoL, but a high score for a symptom scale / item represents a high level of symptomatology / 
problems. All scoring will follow the scoring procedures defined by the EORTC Scoring 
Manual (Fayers et al 2001).
7.2.10.2 EQ-5D-5L 
The EQ-5D-5L (tablet version) is a standardized measure of health utility that provides a single 
index value for one’s health status. The EQ-5D-5L is frequently used for economic evaluations 
of health care and has been shown to be a valid and reliable instrument (The EuroQol Group 
1990, Rabin 2001). The EQ-5D-5L contains one item for each of five dimensions of HRQOL 
(i.e., mobility, self-care, usual activities, pain or discomfort, and anxiety or depression). 
Response options for each item vary from having no problems (e.g., “…no problems walking 
about”), moderate problems (e.g., “…some problems walking about”), or extreme problems 
(e.g., “…unable to walk about”). Patient responses to the five dimensions of HRQOL reflect a 
specific health state that corresponds to a population preference weight for that state on a 
continuous scale of 0 (death) to 1 (perfect health). A visual analog scale (ranging from 0 to 100) 

Novartis
Confidential
Page 99
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
is also included to capture patient’s rating of their overall health status. Higher scores of the 
EQ-5D-5L represent better health states. All scoring and handling of data will follow the User’s 
Guide defined by the EuroQoL Group (van Reenen and Janssen 2015).

Safety monitoring and reporting
8.1
Adverse events
8.1.1
Definitions and reporting
An adverse event is defined as the appearance of (or worsening of any pre-existing) undesirable 
sign(s), symptom(s), or medical condition(s) that occur after patient’s signed informed consent 
has been obtained.
Abnormal laboratory values or test results occurring after informed consent constitute adverse 
events only if they induce clinical signs or symptoms, are considered clinically significant, 
require therapy (e.g., hematologic abnormality that requires transfusion or hematological stem 
cell support), or require changes in study medication(s).
Adverse events that begin or worsen after informed consent should be recorded in the Adverse 
Events CRF. Conditions that were already present at the time of informed consent should be 
recorded in the Medical History page of the patient’s CRF. Adverse event monitoring should 
be continued for at least: 

150 days following the last dose of PDR001 OR

Until the start of a new post treatment antineoplastic medication if administered during the 
period between the 30-Day safety follow up and 150-Day safety follow-up. If a patient 
starts a post treatment antineoplastic therapy after the 30-Day safety follow-up, then only 
adverse events suspected to be related to study treatment should be collected out to 150 
days after discontinuation of PDR001. 
Adverse events (including lab abnormalities that constitute AEs) should be described using a 
diagnosis whenever possible, rather than individual underlying signs and symptoms. When a 
clear diagnosis cannot be identified, each sign or symptom should be reported as a separate 
Adverse Event.
Adverse events will be assessed and graded according to the Common Terminology Criteria for 
Adverse Events (CTCAE) version 4.03.
Grade 1 to 5 will be used to characterize the severity of the Adverse Event.
If CTCAE grading does not exist for an adverse event, the severity of mild, moderate, severe, 
and life-threatening, death related to the AE corresponding respectively to Grades 1 - 5, will be 
used. Information about any deaths (related to an Adverse Event or not) will also be collected 
through a Death form.
The occurrence of adverse events should be sought by non-directive questioning of the patient 
(patient) during the screening process after signing informed consent and at each visit during 
the study. Adverse events also may be detected when they are volunteered by the patient (patient) 

Novartis
Confidential
Page 100
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
during the screening process or between visits, or through physical examination, laboratory test, 
or other assessments. As far as possible, each adverse event should be evaluated to determine:
1. The severity grade (CTCAE Grade 1-5)
2. Its duration (Start and end dates) 
3. Its relationship to the study treatment (Reasonable possibility that AE is related: No, Yes)
Action taken with respect to study or investigational treatment (none, dose adjusted, 
temporarily interrupted, permanently discontinued, unknown, not applicable)
4. Whether medication or therapy was given (no concomitant medication/non-drug therapy, 
concomitant medication/non-drug therapy)
5. Whether it is serious, where a serious adverse event (SAE) is defined as in Section 8.2.1
and which seriousness criteria have been met 
If the event worsens the event should be reported a second time in the CRF noting the start date 
when the event worsens in toxicity. For grade 3 and 4 adverse events only, if improvement to a 
lower grade is determined a new entry for this event should be reported in the CRF noting the 
start date when the event improved from having been Grade 3 or Grade 4.
All adverse events should be treated appropriately. If a concomitant medication or non-drug 
therapy is given, this action should be recorded on the Adverse Event CRF.
Once an adverse event is detected, it should be followed until its resolution or until it is judged 
to be permanent, and assessment should be made at each visit (or more frequently, if necessary) 
of any changes in severity, the suspected relationship to the study treatment, the interventions 
required to treat it, and the outcome.
Progression of malignancy (including fatal outcomes), if documented by use of appropriate 
method (for example, as per RECIST criteria for solid tumors), should not be reported as a 
serious adverse event.
Adverse events separate from the progression of malignancy (example, deep vein thrombosis 
at the time of progression or hemoptysis concurrent with finding of disease progression) will 
be reported as per usual guidelines used for such events with proper attribution regarding 
relatedness to the drug.
8.1.2
Laboratory test abnormalities
8.1.2.1
Definitions and reporting
Laboratory abnormalities that constitute an Adverse event in their own right (are considered 
clinically significant, induce clinical signs or symptoms, require concomitant therapy or require 
changes in study treatment), should be recorded on the Adverse Events CRF. Whenever 
possible, a diagnosis, rather than a symptom should be provided (e.g. anemia instead of low 
hemoglobin). Laboratory abnormalities that meet the criteria for Adverse Events should be 
followed until they have returned to normal or an adequate explanation of the abnormality is 
found. When an abnormal laboratory or test result corresponds to a sign/symptom of an already 
reported adverse event, it is not necessary to separately record the lab/test result as an additional 
event.

Novartis
Confidential
Page 101
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
Laboratory abnormalities, that do not meet the definition of an adverse event, should not be 
reported as adverse events. A Grade 3 or 4 event (severe) as per CTCAE does not automatically 
indicate a SAE unless it meets the definition of serious as defined below and/or as per 
investigator’s discretion. A dose hold or medication for the lab abnormality may be required by 
the protocol in which case the lab abnormality would still, by definition, be an adverse event 
and must be reported as such.
8.1.3
Adverse events of special interest 
Adverse events of special interest (AESI) are defined as events (serious or non-serious) which 
are ones of scientific and medical concern specific to the sponsor’s product or program, for 
which ongoing monitoring and rapid communication by the investigator to the sponsor may be 
appropriate. Such events may require further investigation in order to characterize and 
understand them. 
Adverse events of special interest are defined on the basis of an ongoing review of the safety 
data. The following AESIs are discussed in detail in the latest [Investigator Brochure]:

Endocrinopathies (Hypothyroidism, hyperthyroidism, diabetes, hypophysitis and 
hypopituitarism)

Pneumonitis

Diarrhea/colitis

Hepatitis

Nephritis

Encephalitis

Skin/rash
8.2
Serious adverse events
8.2.1
Definitions
Serious adverse event (SAE) is defined as one of the following:

Is fatal or life-threatening

Results in persistent or significant disability/incapacity

Constitutes a congenital anomaly/birth defect

Is medically significant, i.e., defined as an event that jeopardizes the patient or may 
require medical or surgical intervention to prevent one of the outcomes listed above

Requires inpatient hospitalization or prolongation of existing hospitalization, 

Note that hospitalizations for the following reasons should not be reported as serious 
adverse events:

Routine treatment or monitoring of the studied indication, not associated with any 
deterioration in condition 

Elective or pre-planned treatment for a pre-existing condition that is unrelated to the 
indication under study and has not worsened since signing the informed consent

Novartis
Confidential
Page 102
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201

Social reasons and respite care in the absence of any deterioration in the patient’s 
general condition

Note that treatment on an emergency outpatient basis that does not result in hospital 
admission and involves an event not fulfilling any of the definitions of a SAE given above 
is not a serious adverse event
8.2.2
Reporting
To ensure patient safety, every SAE, regardless of suspected causality, occurring after the 
patient has provided informed consent must be reported to Novartis within 24 hours of learning 
of its occurrence and until:

Suspected SAEs up to 150-Day safety follow-up and beyond

Non-suspected SAEs up to 150-Day safety follow-up or start of new post treatment anti-
neoplastic medication if administered during the period between the 30-Day safety follow-
up and 150-Day safety follow-up, whichever is sooner (see Appendix 3)
If a patient starts a post treatment antineoplastic therapy after the 30-Day safety follow-up, then 
only SAEs suspected to be related to study treatment should be collected out to 150 days after 
discontinuation of PDR001. SAEs suspected to be related to PDR001 will continue to be 
collected beyond the 150-Day safety follow-up visit.
Any additional information for the SAE including complications, progression of the initial SAE, 
and recurrent episodes must be reported as follow-up to the original episode within 24 hours of 
the investigator receiving the follow-up information. An SAE occurring at a different time 
interval or otherwise considered completely unrelated to a previously reported one should be 
reported separately as a new event.
Any SAEs experienced after the reporting period described above should only be reported to 
Novartis if the investigator suspects a causal relationship to the study treatment.  
Information about all SAEs is collected and recorded on the Serious Adverse Event Report 
Form; all applicable sections of the form must be completed in order to provide a clinically 
thorough report. The investigator must assess and record the relationship of each SAE to each 
specific study treatment (if there is more than one study treatment), complete the SAE Report 
Form in English, and submit the completed form within 24 hours to Novartis. Detailed 
instructions regarding the SAE submission process and requirements for signatures are to be 
found in the investigator folder provided to each site.
Follow-up information is submitted in the same way as the original SAE Report. Each re-
occurrence, complication, or progression of the original event should be reported as a follow-
up to that event regardless of when it occurs. The follow-up information should describe 
whether the event has resolved or continues, if and how it was treated, whether the blind was 
broken or not, and whether the patient continued or withdrew from study participation.
If the SAE is not previously documented in the Investigator’s Brochure or Package Insert (new 
occurrence) and is thought to be related to the Novartis study treatment, an oncology Novartis 
Chief Medical Office and Patient Safety (CMO&PS) department associate may urgently require 
further information from the investigator for Health Authority reporting. Novartis may need to 
issue an Investigator Notification (IN), to inform all investigators involved in any study with 

Novartis
Confidential

the same drug that this SAE has been reported. Suspected Unexpected Serious Adverse 
Reactions (SUSARs) will be collected and reported to the competent authorities and relevant 
ethics committees in accordance with Directive 2001/20/EC or as per national regulatory 
requirements in participating countries.

8.4
Pregnancies
To ensure patient safety, each pregnancy occurring while the patient is on study treatment must 
be reported to Novartis within 24 hours of learning of its occurrence. The pregnancy should be 
followed up to determine outcome, including spontaneous or voluntary termination, details of 
the birth, and the presence or absence of any birth defects, congenital abnormalities, or maternal 
and/or newborn complications.
Pregnancy should be recorded on a Clinical Trial Pregnancy Form and reported by the 
investigator to the oncology Novartis CMO&PS. Pregnancy follow-up should be recorded on 
the same form and should include an assessment of the possible relationship to the study 
treatment any pregnancy outcome. Any SAE experienced during pregnancy must be reported 
on the SAE Report Form.
Pregnancy outcomes should be collected for the female partners of any males who took study 
treatment in this study. Consent to report information regarding these pregnancy outcomes 
should be obtained from the mother.
8.5
Warnings and precautions
No evidence available at the time of the approval of this study protocol indicated that special 
warnings or precautions were appropriate, other than those noted in the provided Investigator 
Brochure. Additional safety information collected between IB updates will be communicated 
in the form of Investigator Notifications. This information will be included in the patient 
informed consent and should be discussed with the patient during the study as needed.

Data collection and management
9.1
Data confidentiality
Information about study patient will be kept confidential and managed under the applicable 
laws and regulations. Those regulations require a signed patient authorization informing the 
patient of the following:

What protected health information (PHI) will be collected from patients in this study

Who will have access to that information and why

Who will use or disclose that information

The rights of a research subject to revoke their authorization for use of their PHI.
In the event that a patient revokes authorization to collect or use PHI, the investigator, by 
regulation, retains the ability to use all information collected prior to the revocation of patient
authorization. For patients that have revoked authorization to collect or use PHI, attempts 
should be made to obtain permission to collect follow-up safety information (e.g. has the patient
experienced any new or worsened AEs) at the end of their scheduled study period.
The data collection system for this study uses built-in security features to encrypt all data for 
transmission in both directions, preventing unauthorized access to confidential participant 
information. Access to the system will be controlled by a sequence of individually assigned
user identification codes and passwords, made available only to authorized personnel who have 
completed prerequisite training.
Prior to entering key sensitive personally identifiable information (Patient Initials and exact 
Date of Birth), the system will prompt site to verify that this data is allowed to be collected. If 
the site indicates that country rules or ethics committee standards do not permit collection of 
these items, the system will not solicit Patient Initials. Year of birth will be solicited (in the 
place of exact date of birth) to establish that the patient satisfies protocol age requirements and 
to enable appropriate age-related normal ranges to be used in assessing laboratory test results.
9.2
Site monitoring
Before study initiation, at a site initiation visit or at an investigator’s meeting, Novartis 
personnel (or designated CRO) will review the protocol and CRFs with the investigators and 
their staff. During the study, the field monitor will visit the site regularly to check the 
completeness of patient records, the accuracy of entries on the CRFs, the adherence to the 
protocol to Good Clinical Practice, the progress of enrollment, and to ensure that study 
treatment is being stored, dispensed, and accounted for according to specifications. Key study 
personnel must be available to assist the field monitor during these visits.
The investigator must maintain source documents for each patient in the study, consisting of 
case and visit notes (hospital or clinic medical records) containing demographic and medical 
information, laboratory data, electrocardiograms, and the results of any other tests or 
assessments. All information recorded on CRFs must be traceable to source documents in the 
patient's file. The investigator must also keep the original signed informed consent form (a 
signed copy is given to the patient).

Novartis
Confidential
Page 105
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
The investigator must give the monitor access to all relevant source documents to confirm their 
consistency with the CRF entries. Novartis monitoring standards require full verification for the 
presence of informed consent, adherence to the inclusion/exclusion criteria and documentation 
of SAEs. Additional checks of the consistency of the source data with the CRFs are performed 
according to the study-specific monitoring plan.
9.3
Data collection
Designated investigator staff will enter the data required by the protocol into the Electronic 
Case Report Forms (eCRF). The eCRFs have been built using fully validated secure web-
enabled software that conforms to 21 CFR Part 11 requirements, Investigator site staff will not 
be given access to the EDC system until they have been trained. Automatic validation programs 
check for data discrepancies in the eCRFs and allow modification or verification of the entered 
data by the investigator staff.
The Principal Investigator is responsible for assuring that the data entered into eCRF is complete, 
accurate, and that entry and updates are performed in a timely manner.
 PK sampling, Laboratory samples for hematology, 
chemistry, coagulation (analyzed by central laboratory), Imaging, patient questionnaires
(ePRO), will be collected at investigator sites.
9.4
Database management and quality control
For studies using eCRFs, Novartis personnel (or designated CRO) will review the data entered 
by investigational staff for completeness and accuracy. Electronic data queries stating the nature 
of the problem and requesting clarification will be created for discrepancies and missing values 
and sent to the investigational site via the EDC system. Designated investigator site staff is
required to respond promptly to queries and to make any necessary changes to the data.
Concomitant treatments and prior medications entered into the database will be coded using the 
WHO Drug Reference List, which employs the Anatomical Therapeutic Chemical classification 
system. Medical history/current medical conditions and adverse events will be coded using the 
Medical dictionary for regulatory activities (MedDRA) terminology.
Samples and/or data will be processed centrally and the results will be sent electronically to 
Novartis. The site staff designated by the investigator will enter the information required by the 
protocol onto the eCRFs as well as onto the designated CRO’s requisition form. One copy of 
the requisition form will be forwarded to the central lab along with the corresponding samples 
with required information (including study number, subject ID) and one copy will be retain by 
the site.
Patient questionnaires data will be entered into an electronic PRO by the patient. The system 
will be supplied by a vendor(s), who will also manage the database. The database will be sent 
electronically to Novartis personnel For EDC studies, after database lock, the investigator will 
receive a CD-ROM or paper copies of the patient data for archiving at the investigational site.

Statistical methods and data analysis
Cut-off date for the primary safety and efficacy analysis will be 1 year after Last Patient First 
Treatment (LPFT) in the initially enrolled well-differentiated NET group. This analysis will 
include data from patients with well-differentiated NET and poorly-differentiated GEP-NEC 
groups. It is expected that at the time of this analysis all patients from the original poorly-
differentiated GEP-NEC group will have at least 11 months follow-up. This analysis will be 
summarized in a CSR.
The additional data for any patients continuing to be followed up past this time, as allowed by 
the protocol, will be further summarized in a final study report after all patients discontinued 
treatment and completed the safety follow-up. 
All analyses will be performed separately for the two groups of well-differentiated NET and 
poorly-differentiated GEP-NEC unless otherwise specified. Patients will be analyzed according 
to the group they were assigned at baseline. 
It is planned that the data from participating centers in this protocol will be combined, so that 
an adequate number of patients will be available for analysis. 
Except if otherwise specified, categorical data will be presented as contingency tables 
(frequencies and percentages). For continuous data summary statistics of mean, standard 
deviation, median, minimum, and maximum will be presented.
Screen failure patients are those who signed the informed consent, but never started the study 
treatment for any reason. For these patients, the eCRF data collected will not be included in 
analyses, but will be reported in the clinical study report (CSR) as separate listings.
10.1

10.2
Patient demographics/other baseline characteristics
Demographic and other baseline data including disease characteristics will be listed and
summarized descriptively for all patients for the FAS.
Categorical data will be presented as frequencies and percentages. For continuous data, mean, 
standard deviation, median, minimum, and maximum will be presented.
Relevant medical histories and current medical at baseline will be summarized by system organ 
class and preferred term for all patients.
10.3
Treatments (study treatment, concomitant therapies, 
compliance)
The Safety set will be used for the analyses below. Categorical data will be summarized as 
frequencies and percentages. For continuous data, mean, standard deviation, median, 25th and 
75th percentiles, minimum, and maximum will be presented. 
The duration of exposure in weeks to PDR001 as well as the dose intensity (computed as the 
ratio of actual cumulative dose received and actual duration of exposure) and the relative dose 
intensity (computed as the ratio of dose intensity and planned dose intensity) will be 
summarized by means of descriptive statistics using the Safety set. 
The number of patients with dose adjustments (reductions, interruption, or permanent 
discontinuation) and the reasons will be summarized for all patients and all dosing data will be 
listed.
Concomitant medications and significant non-drug therapies prior to and after the start of the 
study treatment will be listed and summarized according to the Anatomical Therapeutic 
Chemical (ATC) classification system for all patients. 
10.4
Primary objective
The primary objective is to estimate the antitumor activity of PDR001 as a single agent in well-
differentiated NET and poorly-differentiated GEP-NEC groups.

Page 108
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
10.4.1
Variable
The primary efficacy variable of the study is overall response rate (ORR), defined as the 
proportion of patients with best overall response (BOR) of complete response (CR) or partial 
response (PR), as per blinded independent review committee. ORR will be evaluated according 
to RECIST 1.1 (see Appendix 1 for details).
ORR will be calculated within each group based on the FAS and according to the ITT principle. 
10.4.2
Statistical hypothesis, model, and method of analysis
No formal hypothesis testing will be conducted. The objective of the study is to demonstrate 
the antitumor activity of PDR001 as measured by ORR.
The response rate within each group on the FAS population with 95% two-sided confidence 
interval (exact method) will be computed. 
Group 1: Well-differentiated NET 
The results in this group will be considered a success if both of the following conditions are 
met:
1. a clinically relevant response rate of at least 10% is observed
2. 95% two-sided CI for ORR excludes the value 3%. 
With 90 treated patients enrolled, the success corresponds to at least 9 responders observed (i.e. 
a response rate of 10% with [4.7; 18.1] 95% CI).
In the absence of historical comparator in this setting, response rates reported in placebo arms 
of previous randomized phase III studies in earlier lines of treatment can be considered as a 
valid historical reference for ORR in well-differentiated NET (Table 1-1). A 95% two-sided CI 
excluding the value 3% will ensure that the clinically relevant observed response rate is 
significantly higher than expected placebo response rate.
Group 2: Poorly-differentiated GEP-NEC
This group will enroll approximately 20 patients. Estimates of the ORR along with 95% two-
sided CI will be presented. Additionally, the interval probabilities for the true ORR lying within 
the intervals stated below will be computed.

0 - <3%    
unacceptable efficacy

3% - <10%    
limited efficacy

10% - <20%  
moderate efficacy

20%  
clinically relevant efficacy
For this analysis a prior distribution for the parameter of interest, ORR, must be specified. For 
the current study, the prior clinical assumption for PDR001 in the selected patient population is 
used in order to derive a minimally informative unimodal Beta prior distribution that reflects 
the level of uncertainty around ORR before starting the current trial (Neuenschwander et al 
2008). The prior mean ORR is set to be equal to 15% and the parameters of the minimally 
informative Beta prior distribution of ORR have been set up as follows:

a/(a+b) = 0.15

Novartis
Confidential
Page 109
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201

a = 0.176

b = 1.0
At the primary analysis, this prior distribution will be updated with observed ORR data and 
probabilities that the true ORR lies within the above intervals will be reported.
10.4.3
Handling of missing values/censoring/discontinuations
For the computation of ORR, all confirmed responses (CR or PR) reported up to the analysis 
cut-off will be included. Patients with no valid radiological assessment or unconfirmed 
responses will be considered as non-responders. In particular, patients with CR or PR at the last 
radiological assessment prior to cut-off and no response at the previous assessment are by 
definition unconfirmed and will be considered as non-responders for the primary analysis.
10.4.4
Supportive and Sensitivity analyses
A sensitivity analysis considering patients with unconfirmed PR or CR (i.e. with PR or CR at 
the last assessment prior to the cutoff and ongoing in efficacy follow-up) as responders may be 
performed.
Primary and sensitivity analyses will be repeated using overall response based on local review.
10.5
Secondary objectives
The key secondary objective in this study is to estimate efficacy of PDR001 in each group using
the duration of response per RECIST 1.1 and based on tumor response data per BIRC. 
Furthermore, tumor related endpoints such as disease control rate (DCR), time to response (TTR) 
and PFS will be evaluated based on RECIST 1.1 and irRECIST. Additional secondary endpoints 
include overall survival rate at 1 and 2 years, HRQoL, CgA and NSE, PK and safety.
Antitumor activity (assessed by ORR and DoR per RECIST 1.1 and BIRC) in each of the three 
well-differentiated NET cohorts (pancreatic, GI, thoracic) will also be evaluated as secondary 
endpoint. If heterogeneity in ORR is observed among the three cohorts, a probabilistic 
evaluation, using simulations or any other appropriate method, will be conducted in order to 
assess observed difference. Details will be provided in the statistical analysis plan (SAP).
10.5.1
Key secondary objective(s)
Duration of Response (DoR)
Duration of response (DOR) only applies to patients whose best overall response is complete 
response (CR) or partial response (PR) based on tumor response data per blinded independent 
central review. DOR will be evaluated according to RECIST 1.1 (see Appendix 1 for details).
The start date is the date of first documented response of CR or PR (i.e., the start date of 
response, not the date when response was confirmed), and the end date is defined as the date of 
the first documented progression or death due to underlying cancer. Patients continuing without 
progression or death due to underlying cancer will be censored at the date of their last adequate 
tumor assessment. DOR based on RECIST 1.1 will be listed and summarized for all patients in 
the FAS with confirmed BOR of CR or PR.

10.5.2
Other secondary efficacy objectives
All secondary efficacy endpoints according to RECIST 1.1 or irRECIST will be based on tumor 
assessments as per BIRC. The local radiology assessments will be used as supportive analysis.
10.5.2.1 Efficacy endpoints according to RECIST 1.1
Disease control rate (DCR) 
DCR is defined as the proportion of patients with best overall response of CR, PR or SD 
according to RECIST 1.1 criteria and as per central review (see Appendix 1 for details). 
DCR will be calculated based on the FAS. DCR and its 95% confidence interval will be 
presented for all patients. 
Time to response (TTR)
Time to response (TTR) is defined as the time from the date of start of treatment to the first 
documented response of either complete response (CR) or partial response (PR), which must 
be subsequently confirmed (although date of initial response is used, not date of confirmation). 
TTR will be evaluated according to RECIST 1.1 (see Appendix 1 for details). 
All patients in the FAS will be included in TTR calculations. Patients without a confirmed CR 
or PR will be censored at the study-maximum follow-up time (i.e., Last Patient Last Visit 
(LPLV)-First Patient First Visit (FPFV)) for patients with a PFS event (i.e., disease progression 
or death due to any cause), or at the date of the last adequate tumor assessment for patients 
without a PFS event. TTR will be listed and summarized for all patients. The distribution of 
time to response will be estimated using the Kaplan-Meier method only if a sufficient number 
of responses is observed. 
Progression-free survival (PFS)
PFS is defined as the time from the date of first dose to the date of the first documented 
radiological progression or death due to any cause. PFS will be assessed via central review 
according to RECIST 1.1 (see Appendix 1 for further details). PFS will be censored if no PFS 
event is observed before the analysis cut-off date. The censoring date will be the date of the last 
adequate tumor assessment prior to cut-off.
PFS based on RECIST 1.1 will be analyzed in the FAS population. The PFS distribution will 
be estimated using the Kaplan-Meier method, and the Kaplan-Meier curves, medians and 95% 
confidence intervals of the medians will be presented for all patients. 
10.5.2.2 Efficacy endpoints according to irRECIST 
The definitions of the endpoints based on irRECIST are similar to those based on RECIST 1.1 
and are provided in the Appendix 2. The following endpoints will be analyzed in the same way 
as described above for the endpoints based on RECIST:

irORR

irDoR

irTTR

10.5.2.3 Overall survival rate at 1 year and 2 years
OS is defined as the time from date of start of treatment to date of death due to any cause. If a 
patient is not known to have died, then OS will be censored at the latest date the patient was 
known to be alive (on or before the cut-off date). The OS distribution will be estimated using 
the Kaplan-Meier method, and the Kaplan-Meier curves. 
Survival estimates at 1 year and at 2 years will be computed with 95% confidence interval.
10.5.3
Safety objectives
10.5.3.1 Analysis set and grouping for the analyses
For all safety analyses, the safety set will be used. All listings and tables will be presented 
separately for the well-differentiated NET and the poorly-differentiated GEP-NEC groups. In 
addition, pooled safety analyses based on all patients will be produced.
The overall observation period will be divided into three mutually exclusive segments:
1. Pre-treatment period: from day of patient’s informed consent to the day before first dose 
of study medication
2. On-treatment period: from day of first dose of study medication to 30 days after last dose 
of PDR001 
3. Post-treatment period: starting at day 31 after last dose of study medication.
10.5.3.2 Adverse events (AEs)
Summary tables for adverse events (AEs) will include only AEs that started or worsened during 
the on-treatment period, the treatment-emergent AEs. Additional summaries will be displayed 
to report deaths, all AEs, AEs related to study treatment, all SAEs and SAEs related to study 
treatment collected up to 150 days after last administration of PDR001.
The incidence of treatment-emergent adverse events (new or worsening from baseline) will be 
summarized by system organ class and or preferred term, severity (based on CTCAE grades), 
type of adverse event, relation to study treatment. 
Serious adverse events, non-serious adverse events and adverse events of special interest (AESI)
during the on-treatment period will be tabulated. 
All deaths (on-treatment and post-treatment) will be summarized.
All AEs, deaths and serious adverse events (including those from the pre and post-treatment 
periods) will be listed and those starting during the post-treatment period will be flagged.
Project-specific AESIs should be defined in the case retrieval strategy (CRS) with regular 
updates whenever necessary, see also Section 8.1.3.

10.5.3.3 Laboratory abnormalities
Grading of laboratory values will be assigned programmatically as per NCI Common 
Terminology Criteria for Adverse Events (CTCAE) version 4.03. The calculation of CTCAE 
grades will be based on the observed laboratory values only, clinical assessments will not be 
taken into account.
CTCAE Grade 0 will be assigned for all non-missing values not graded as 1 or higher. Grade 5 
will not be applicable.
For laboratory tests where grades are not defined by CTCAE v4.03, results will be categorized 
as low/normal/high based on laboratory normal ranges.
The following listings/summaries will be generated separately for hematology, and 
biochemistry tests:

Listing of all laboratory data with values flagged to show the corresponding CTCAE 
v4.03 grades if applicable and the classifications relative to the laboratory normal ranges
For laboratory tests where grades are defined by CTCAE v4.03

Worst post-baseline CTCAE grade (regardless of the baseline status). Each patient will be 
counted only once for the worst grade observed post-baseline.

Shift tables using CTCAE v4.03 grades to compare baseline to the worst on-treatment 
value
For laboratory tests where grades are not defined by CTCAE v4.03,

Shift tables using the low/normal/high/ (low and high) classification to compare baseline 
to the worst on-treatment value.
In addition to the above mentioned tables and listings, other exploratory analyses, for example 
figures plotting time course of raw or change in laboratory tests over time or box plots might 
be specified in the statistical analysis plan (SAP).
10.5.3.4 Other safety data
ECG

12-lead ECGs including PR, QRS, QT, QTcF intervals and heart rate (HR) will be 
obtained for each patient during the study. ECG data will be read and interpreted locally. 

Categorical Analysis of QT/QTc interval data based on the number of patients meeting or
exceeding predefined limits in terms of absolute QT/QTc intervals or changes from 
baseline will be presented. In addition, a listing of these patients will be produced. 
Vital signs
Data on vital signs will be tabulated and listed, notable values will be flagged.

Efficacy analyses as per local review
The analyses based on the efficacy endpoints according to RECIST 1.1 and irRECIST 
(described in Section 10.5.2.1 and Section 10.5.2.2) will be repeated using local radiology 
review.
10.5.3.6 Tolerability
Tolerability of study treatment will be assessed by summarizing the number of dose 
interruptions and dose reductions. Reasons for dose interruptions and dose reductions will be 
listed and summarized (see Section 10.3).
10.5.4
Pharmacokinetics
Descriptive statistics (n, m (number of non-zero concentrations), mean, CV%, SD, median, 
geometric mean, geometric CV%, minimum and maximum) for PDR001 concentrations will 
be presented at each scheduled timepoint. For PDR001, pre-dose concentrations collected 
before dose administration on Day 1 of Cycle 2+ are Ctrough.
All concentration data for PDR001 will be displayed graphically.
10.5.4.1 Data handling principles
Missing values for any PK parameters or concentrations will not be imputed and will be treated 
as missing. 
Below the limit of quantitation (BLQ) values will be set to zero by the Bioanalyst, and will be 
displayed in the listings as zero and flagged. BLQ values will be treated as missing for the 
calculation of the geometric means and geometric CV%. 
10.5.4.2 Population pharmacokinetic analysis
If data permit, a mixed-effects model may be applied to the serum PDR001 concentration-time 
data to generate post hoc estimates of pharmacokinetic parameters using NONMEM to 
characterize PDR001 exposure. If there are sufficient data for analysis, the details of the 
population pharmacokinetic analyses will be provided in a separate reporting and analysis plan, 
and the results may be reported in a separate population pharmacokinetic report. Data from this 
and other studies may be pooled for analysis.
10.5.5
Immunogenicity
Immunogenicity will be characterized descriptively by tabulating anti-drug antibodies (ADA) 
prevalence at baseline and ADA incidence on-treatment.
10.5.6
CgA and NSE
The biochemical response will be assessed using the change from baseline for CgA and NSE 
levels. 

Novartis

Change from baseline in CgA and NSE will be summarized using descriptive statistics for all 
patients. CgA and NSE values might be analyzed on the logarithmic scale if their observed 
distribution is found be right skewed.
 
 
10.5.6.1 Data handling principles
The lower limit of quantification (LLOQ) values for CgA and NSE will be specified by the 
laboratory running the assay.
Measures below the LLOQ will be handled as follows:

If the proportion of measures below LLOQ is below 15%, all values specified as below 
LLOQ will be imputed by half of the LLOQ and the standard set of summary statistics 
will be used.

If the proportion of measures below LLOQ is above 15%, but below 50%, an alternative 
choice of summary statistics requiring no imputation such as percentiles may be used.

Otherwise the data will be missing

When both baseline and post baseline values are below LLOQ, change from baseline will 
not be imputed and reported as missing.
Values below LLOQ will be shown as such in listings. All available data points obtained at 
scheduled and unscheduled visits will be considered for the analysis. 
10.5.7
Resource utilization 
Not applicable
10.5.8
Patient-reported outcomes 
The EORTC QLQ-C30 questionnaire and the EQ-5D-5L will be used to collect patient’s QoL 
data. The global health status/QoL scale score of the QLQ-C30 and the health status index score 
of the EQ-5D-5L are identified as the primary patient-reported outcome variables of interest.
Physical functioning, emotional functioning and social functioning scale scores of the QLQ-
C30, and overall health status of the EQ-5D-5L are identified as secondary patient-reported 
QoL variables of interest. 
Scoring of PRO data and methods for handling of missing items or missing assessments will be 
handled according to the scoring manual and user guide for each respective patient 
questionnaire (Fayers 2001; van Reenen and Janssen 2015). No imputation procedures will be 
applied for missing items or missing assessments. Five health states from the EQ-5D-5L will 
be converted to index values during the data analysis stage and will be further defined in the 
analysis plan. In addition, the visual analog scale (ranging from 0 to 100) from the EQ-5D-5L 
will be evaluated for patient’s rating of their overall health status.
The number of patients completing each questionnaire and the number of missing or incomplete 
assessments will be summarized for each scheduled assessment time points.
The FAS will be used for analyzing PRO data. No formal statistical tests will be performed. For 
the main analysis, patients with baseline and at least one non-missing post-baseline assessment

will be included. All available data until the end of treatment will be used in the repeated 
measures models for longitudinal data to assess the treatment effect over time. 
A time-to-event approach may be considered as the secondary analysis, in which patients with 
no events will be censored at the latest available non-missing timepoint until end of treatment. 
Details will be specified in the SAP.
Descriptive statistics will be used to summarize the PRO scores and change from baseline in 
scales of the EORTC QLQ-C30 and health states, overall health status, and index values of the 
EQ-5D-5L at each scheduled assessment time point.

Interim analysis
An interim analysis for preliminary assessment of PDR001 in this patient population will be 
conducted once at least 30 patients from the well-differentiated NET group have 3 radiological 
assessments (week 24) or have discontinued study for any other reason. All available efficacy 
and safety data from the well-differentiated NET and poorly-differentiated GEP-NEC groups 
up to the cut-off date will be used for IA and reviewed by the Steering Committee. It is expected 
that at the time of the interim analysis all patients from the poorly-differentiated GEP-NEC 
group have at least undergone 2 radiological assessments. The study will not be stopped at the 
interim analysis for efficacy reasons regardless of efficacy results and will continue until mature 
data for all patients become available. If the study is stopped for safety reasons, the treatment 
continuation of patients who are deriving benefit from PDR001 treatment will be assessed on a 
case-by-case basis in consultation with the sponsor.

reported in Table 1-1 can serve as a reference in the well-differentiated NET group. A 3% ORR 
is therefore considered as a reasonable reference while an improvement up to 10% is considered 
as clinically meaningful in this patient population.
Total sample size of 90 patients was chosen such that with an observed 10% response rate, the 
corresponding 95% CI excludes the value 3%.
Approximately thirty patients will be recruited in each cohort NET cohort: pancreatic, GI and 
thoracic. 
Operating characteristics in the well-differentiated NET group are given in Table 10-1. A 
sample size of 90 patients ensures a 90% probability of success if the true ORR is 15%.

Group 2: Poorly-differentiated GEP-NEC
Approximately 20 patients will be enrolled in the poorly-differentiated GEP-NEC group. The 
operating characteristics are shown in Table 10-3 and Table 10-4. With the planned sample size 
the probability to observe at least moderate efficacy (10% ORR) is more than 80% if the true 
ORR is 15%. Posterior probability of a true ORR of at least moderate efficacy was computed
for different scenarios assuming a minimally informative prior with Beta distribution and the

11.3
Informed consent procedures
Eligible patients may only be included in the study after providing written (witnessed, where 
required by law or regulation), IRB/IEC/REB-approved informed consent 
Informed consent must be obtained before conducting any study-specific procedures (i.e. all of 
the procedures described in the protocol). The process of obtaining informed consent should be 
documented in the patient source documents. The date when a patient’s Informed Consent was 
actually obtained will be captured in their CRFs.
Novartis will provide to investigators, in a separate document, a proposed informed consent 
form (ICF) that is considered appropriate for this study and complies with the ICH GCP 
guideline and regulatory requirements. Any changes to this ICF suggested by the investigator 
must be agreed to by Novartis before submission to the IRB/IEC/REB, and a copy of the 
approved version must be provided to the Novartis monitor after IRB/IEC/REB approval.
Women of child bearing potential should be informed that taking the study medication may 
involve unknown risks to the fetus if pregnancy were to occur during the study and agree that 
in order to participate in the study they must adhere to the contraception requirement for the 
duration of the study. If there is any question that the patient will not reliably comply, they 
should not be entered in the study.
11.4
Discontinuation of the study
Novartis reserves the right to discontinue this study under the conditions specified in the clinical 
study agreement. Specific conditions for terminating the study are outlined in Section 4.4.
11.5
Publication of study protocol and results
Novartis is committed to following high ethical standards for reporting study results for its 
innovative medicine, including the timely communication and publication of clinical trial 
results, whatever their outcome. Novartis assures that the key design elements of this protocol 
will be posted on the publicly accessible database, e.g. www.clinicaltrials.gov before study 
start. . In addition, results of interventional clinical trials in adult patients are posted on 
www.novartisclinicaltrials.com, a publicly accessible database of clinical study results within 
1 year of study completion (i.e., LPLV). 
Novartis follows the ICMJE authorship guidelines (www.icmje.org) and other specific 
guidelines of the journal or congress to which the publication will be submitted

11.6
Study documentation, record keeping and retention of 
documents
Each participating site will maintain appropriate medical and research records for this trial, in 
compliance with Section 4.9 of the ICH E6 GCP, and regulatory and institutional requirements 
for the protection of confidentiality of patients. As part of participating in a Novartis-sponsored 
study, each site will permit authorized representatives of the sponsor(s) and regulatory agencies 
to examine (and when required by applicable law, to copy) clinical records for the purposes of 
quality assurance reviews, audits and evaluation of the study safety and progress.
Source data are all information, original records of clinical findings, observations, or other 
activities in a clinical trial necessary for the reconstruction and evaluation of the trial. Examples 
of these original documents and data records include, but are not limited to, hospital records, 
clinical and office charts, laboratory notes, memoranda, patients’ diaries or evaluation 
checklists, pharmacy dispensing records, recorded data from automated instruments, copies or 
transcriptions certified after verification as being accurate and complete, microfiches, 
photographic negatives, microfilm or magnetic media, x-rays, and patient files and records kept 
at the pharmacy, at the laboratories, and medico-technical departments involved in the clinical 
trial.
Data collection is the responsibility of the clinical trial staff at the site under the supervision of 
the site Principal Investigator. The study case report form (CRF) is the primary data collection 
instrument for the study. The investigator should ensure the accuracy, completeness, legibility, 
and timeliness of the data reported in the CRFs and all other required reports. Data reported on 
the CRF, that are derived from source documents, should be consistent with the source 
documents or the discrepancies should be explained. All data requested on the CRF must be 
recorded. Any missing data must be explained. Any change or correction to a paper CRF should 
be dated, initialed, and explained (if necessary) and should not obscure the original entry. For 
electronic CRFs an audit trail will be maintained by the system. The investigator should retain 
records of the changes and corrections to paper CRFs.
The investigator/institution should maintain the trial documents as specified in Essential 
Documents for the Conduct of a Clinical Trial (ICH E6 Section 8) and as required by applicable 
regulations and/or guidelines. The investigator/institution should take measures to prevent 
accidental or premature destruction of these documents.
Essential documents (written and electronic) should be retained for a period of not less than 
fifteen (15) years from the completion of the Clinical Trial unless sponsor provides written 

Novartis

permission to dispose of them or, requires their retention for an additional period of time 
because of applicable laws, regulations and/or guidelines.
11.7
Confidentiality of study documents and patient records
The investigator must ensure anonymity of the patients; patients must not be identified by names 
in any documents submitted to Novartis. Signed informed consent forms and patient enrollment 
log must be kept strictly confidential to enable patient identification at the site.
11.8
Audits and inspections
Source data/documents must be available to inspections by Novartis or designee or Health 
Authorities.
11.9
Financial disclosures
Financial disclosures should be provided by study personnel who are directly involved in the 
treatment or evaluation of patients at the site - prior to study start.
12
Protocol adherence
Investigators ascertain they will apply due diligence to avoid protocol deviations. Under no 
circumstances should the investigator contact Novartis or its agents, if any, monitoring the study 
to request approval of a protocol deviation, as no authorized deviations are permitted. If the 
investigator feels a protocol deviation would improve the conduct of the study this must be 
considered a protocol amendment, and unless such an amendment is agreed upon by Novartis 
and approved by the IRB/IEC/REB it cannot be implemented. All significant protocol 
deviations will be recorded and reported in the CSR.
12.1
Amendments to the protocol
Any change or addition to the protocol can only be made in a written protocol amendment that 
must be approved by Novartis, Health Authorities where required, and the IRB/IEC/REB. Only 
amendments that are required for patient safety may be implemented prior to IRB/IEC/REB 
approval. Notwithstanding the need for approval of formal protocol amendments, the 
investigator is expected to take any immediate action required for the safety of any patient 
included in this study, even if this action represents a deviation from the protocol. In such cases, 
Novartis should be notified of this action and the IRB/IEC at the study site should be informed 
according to local regulations (e.g. UK requires the notification of urgent safety measures 
within 3 days) but not later than 10 working days.

Introduction
The purpose of this document is to provide the working definitions and rules necessary for a 
consistent and efficient analysis of efficacy for oncology studies in solid tumors. This document 
is based on the RECIST criteria for tumor responses (Therasse et al 2000) and the revised 
RECIST 1.1 guidelines (Eisenhauer et al 2009).
The efficacy assessments described in Section 2 and the definition of best response in 
Section 3.1 are based on the RECIST 1.1 criteria but also give more detailed instructions and 
rules for determination of best response. Section 3.2 is summarizing the “time to event” 
variables and rules which are mainly derived from internal discussions and regulatory 
consultations, as the RECIST criteria do not define these variables in detail. Section 4 of this 
guideline describes data handling and programming rules. This section is to be referred to in 
the SAP (Statistical Analysis Plan) to provide further details needed for programming.

Efficacy assessments
Tumor evaluations are made based on RECIST criteria (Therasse et al 2000), New Guidelines 
to Evaluate the Response to Treatment in Solid Tumors, Journal of National Cancer Institute, 
Vol. 92; 205-16 and revised RECIST guidelines (version 1.1) (Eisenhauer et al 2009) European 
Journal of Cancer; 45:228-247.
2.1
Definitions
2.1.1 Disease measurability
In order to evaluate tumors throughout a study, definitions of measurability are required in order 
to classify lesions appropriately at baseline. In defining measurability, a distinction also needs 
to be made between nodal lesions (pathological lymph nodes) and non-nodal lesions.

Measurable disease - the presence of at least one measurable nodal or non-nodal lesion. 
If the measurable disease is restricted to a solitary lesion, its neoplastic nature should be 
confirmed by cytology/histology.
For patients without measurable disease see Section 3.2.8
Measurable lesions (both nodal and non-nodal)

Measurable non-nodal - As a rule of thumb, the minimum size of a measurable non-nodal 
target lesion at baseline should be no less than double the slice thickness or 10mm 
whichever is greater - e.g. the minimum non-nodal lesion size for CT/MRI with 5mm cuts 
will be 10 mm, for 8 mm contiguous cuts the minimum size will be 16 mm.

Lytic bone lesions or mixed lytic-blastic lesions with identifiable soft tissue components 
that can be evaluated by CT/MRI can be considered as measurable lesions, if the soft 
tissue component meets the definition of measurability.

Protocol No. CPDR001E2201

Measurable nodal lesions (i.e. lymph nodes) - Lymph nodes 15 mm in short axis can be 
considered for selection as target lesions. Lymph nodes measuring 10 mm and <15 mm 
are considered non-measurable. Lymph nodes smaller than 10 mm in short axis at 
baseline, regardless of the slice thickness, are normal and not considered indicative of 
disease.

Cystic lesions: 

Lesions that meet the criteria for radiographically defined simple cysts (i.e., spherical 
structure with a thin, non-irregular, non-nodular and non-enhancing wall, no 
septations, and low CT density [water-like] content) should not be considered as 
malignant lesions (neither measurable nor non-measurable) since they are, by 
definition, simple cysts.

‘Cystic lesions’ thought to represent cystic metastases can be considered as 
measurable lesions, if they meet the definition of measurability described above. 
However, if noncystic lesions are present in the same patient, these are preferred for 
selection as target lesions.

Non-measurable lesions - all other lesions are considered non-measurable, including small 
lesions (e.g. longest diameter <10 mm with CT/MRI or pathological lymph nodes with 
10 to < 15 mm short axis), as well as truly non-measurable lesions e.g., blastic bone 
lesions, leptomeningeal disease, ascites, pleural/pericardial effusion, inflammatory breast 
disease, lymphangitis cutis/pulmonis, abdominal masses/abdominal organomegaly 
identified by physical exam that is not measurable by reproducible imaging techniques.
2.1.2 Eligibility based on measurable disease
If no measurable lesions are identified at baseline, the patient may be allowed to enter the study 
in some situations (e.g. in Phase III studies where PFS is the primary endpoint). However, it is 
recommended that patients be excluded from trials where the main focus is on the Overall 
Response Rate (ORR). Guidance on how patients with just non-measurable disease at baseline 
will be evaluated for response and also handled in the statistical analyses is given in Section 
3.2.8.
2.2
Methods of tumor measurement - general guidelines
In this document, the term “contrast” refers to intravenous (i.v.) contrast.
The following considerations are to be made when evaluating the tumor:

All measurements should be taken and recorded in metric notation (mm), using a ruler or 
calipers. All baseline evaluations should be performed as closely as possible to the 
beginning of treatment and never more than 4 weeks before the beginning of the 
treatment.

Imaging-based evaluation is preferred to evaluation by clinical examination when both 
methods have been used to assess the antitumor effect of a treatment.

For optimal evaluation of patients, the same methods of assessment and technique should 
be used to characterize each identified and reported lesion at baseline and during follow-
up. Contrast-enhanced CT of chest, abdomen and pelvis should preferably be performed 
using a 5 mm slice thickness with a contiguous reconstruction algorithm. CT/MRI scan 

Novartis
Confidential
Page 128
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
slice thickness should not exceed 8 mm cuts using a contiguous reconstruction algorithm. 
If, at baseline, a patient is known to have a medical contraindication to CT contrast or 
develops a contraindication during the trial, the following change in imaging modality will 
be accepted for follow up: a non-contrast CT of chest (MRI not recommended due to 
respiratory artifacts) plus contrast-enhanced MRI of abdomen and pelvis.

A change in methodology can be defined as either a change in contrast use (e.g. keeping 
the same technique, like CT, but switching from with to without contrast use or vice-versa, 
regardless of the justification for the change) or a major change in technique (e.g. from CT 
to MRI, or vice-versa), or a change in any other imaging modality. A change from 
conventional to spiral CT or vice versa will not constitute a major “change in method” for 
the purposes of response assessment. A change in methodology will result by default in a 
UNK overall lesion response assessment as per Novartis calculated response. However, 
another response assessment than the Novartis calculated UNK response may be accepted 
from the investigator or the central blinded reviewer if a definitive response assessment 
can be justified, based on the available information.

FDG-PET: can complement CT scans in assessing progression (particularly possible for 
‘new’ disease). New lesions on the basis of FDG-PET imaging can be identified according 
to the following algorithm:

Negative FDG-PET at baseline, with a positive FDG-PET at follow-up is a sign of PD 
based on a new lesion.

No FDG-PET at baseline with a positive FDG-PET at follow-up:

If new disease is indicated by a positive PET scan but is not confirmed by CT (or some 
other conventional technique such as MRI) at the same assessment, then follow-up 
assessments by CT will be needed to determine if there is truly progression occurring at 
that site. In all cases PD will be the date of confirmation of new disease by CT (or some 
other conventional technique such as MRI) rather than the date of the positive PET scan. 
If there is a positive PET scan without any confirmed progression at that site by CT, then a 
PD cannot be assigned.

If the positive FDG-PET at follow-up corresponds to a pre-existing site of disease on 
CT that is not progressing on the basis of the anatomic images, this is not PD.

Chest x-ray: Lesions on chest x-ray are acceptable as measurable lesions when they 
are clearly defined and surrounded by aerated lung. However, CT is preferable.

Physical exams: Evaluation of lesions by physical examination is accepted when 
lesions are superficial, with at least 10mm size, and can be assessed using calipers. 

Ultrasound: When the primary endpoint of the study is objective response evaluation, 
ultrasound (US) should not be used to measure tumor lesions, unless pre-specified by 
the protocol. It is, however, a possible alternative to clinical measurements of 
superficial palpable lymph nodes, subcutaneous lesions and thyroid nodules. US 
might also be useful to confirm the complete disappearance of superficial lesions 
usually assessed by clinical examination. 

Endoscopy and laparoscopy: The utilization of endoscopy and laparoscopy for 
objective tumor evaluation has not yet been fully and widely validated. Their uses in 
this specific context require sophisticated equipment and a high level of expertise that 

Novartis
Confidential
Page 129
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
may only be available in some centers. Therefore, the utilization of such techniques 
for objective tumor response should be restricted to validation purposes in specialized 
centers. However, such techniques can be useful in confirming complete pathological 
response when biopsies are obtained.

Tumor markers: Tumor markers alone cannot be used to assess response. However, 
some disease specific and more validated tumor markers (e.g. CA-125 for ovarian 
cancer, PSA for prostate cancer, alpha-FP, LDH and Beta-hCG for testicular cancer) 
can be integrated as non-target disease. If markers are initially above the upper 
normal limit they must normalize for a patient to be considered in complete clinical 
response when all lesions have disappeared.

Cytology and histology: Cytology and histology can be used to differentiate between PR 
and CR in rare cases (i.e., after treatment to differentiate between residual benign lesions 
and residual malignant lesions in tumor types such as germ cell tumors). Cytologic 
confirmation of neoplastic nature of any effusion that appears or worsens during treatment 
is required when the measurable tumor has met the criteria for response or stable disease. 
Under such circumstances, the cytologic examination of the fluid collected will permit 
differentiation between response and stable disease (an effusion may be a side effect of the 
treatment) or progressive disease (if the neoplastic origin of the fluid is confirmed).

Clinical examination: Clinical lesions will only be considered measurable when they are 
superficial (i.e., skin nodules and palpable lymph nodes). For the case of skin lesions, 
documentation by color photography, including a ruler to estimate the size of the lesion, is 
recommended.
2.3
Baseline documentation of target and non-target lesions
For the evaluation of lesions at baseline and throughout the study, the lesions are classified at 
baseline as either target or non-target lesions:

Target lesions: All measurable lesions (nodal and non-nodal) up to a maximum of five 
lesions in total (and a maximum of two lesions per organ), representative of all involved 
organs should be identified as target lesions and recorded and measured at baseline. Target 
lesions should be selected on the basis of their size (lesions with the longest diameter) and 
their suitability for accurate repeated measurements (either by imaging techniques or 
clinically). Each target lesion must be uniquely and sequentially numbered on the CRF 
(even if it resides in the same organ).
Minimum target lesion size at baseline

Non-nodal target: Non-nodal target lesions identified by methods for which slice 
thickness is not applicable (e.g. clinical examination, photography) should be at least 10 
mm in longest diameter. See Section 2.1.1.

Nodal target: See Section 2.1.1.
A sum of diameters (long axis for non-nodal lesions, short axis for nodal) for all target lesions 
will be calculated and reported as the baseline sum of diameters (SOD). The baseline sum of 
diameters will be used as reference by which to characterize the objective tumor response. Each 
target lesion identified at baseline must be followed at each subsequent evaluation and 
documented on eCRF.

Novartis
Confidential
Page 130
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201

Non-target lesions: All other lesions are considered non-target lesions, i.e. lesions not 
fulfilling the criteria for target lesions at baseline. Presence or absence or worsening of 
non-target lesions should be assessed throughout the study; measurements of these lesions 
are not required. Multiple non-target lesions involved in the same organ can be assessed as 
a group and recorded as a single item (i.e. multiple liver metastases). Each non-target 
lesion identified at baseline must be followed at each subsequent evaluation and 
documented on eCRF.
2.4
Follow-up evaluation of target and non-target lesions
To assess tumor response, the sum of diameters for all target lesions will be calculated (at 
baseline and throughout the study). At each assessment response is evaluated first separately 
for the target (Table 2-1) and non-target lesions (Table 2-2) identified at baseline. These 
evaluations are then used to calculate the overall lesion response considering both the target and 
non-target lesions together (Table 2-3) as well as the presence or absence of new lesions.
2.4.1 Follow-up and recording of lesions
At each visit and for each lesion the actual date of the scan or procedure which was used for the 
evaluation of each specific lesion should be recorded. This applies to target and non-target 
lesions as well as new lesions that are detected. At the assessment visit all of the separate lesion 
evaluation data are examined by the investigator in order to derive the overall visit response. 
Therefore all such data applicable to a particular visit should be associated with the same 
assessment number.
2.4.1.1
Non-nodal lesions
Following treatment, lesions may have longest diameter measurements smaller than the image
reconstruction interval. Lesions smaller than twice the reconstruction interval are subject to 
substantial “partial volume” effects (i.e., size may be underestimated because of the distance of 
the cut from the longest diameter; such lesions may appear to have responded or progressed on 
subsequent examinations, when, in fact, they remain the same size).
If the lesion has completely disappeared, the lesion size should be reported as 0 mm.
Measurements of non-nodal target lesions that become 5 mm or less in longest diameter are 
likely to be non-reproducible. Therefore, it is recommended to report a default value of 5 mm, 
instead of the actual measurement. This default value is derived from the 5 mm CT slice 
thickness (but should not be changed with varying CT slice thickness). Actual measurement 
should be given for all lesions larger than 5 mm in longest diameter irrespective of slice 
thickness/reconstruction interval.
In other cases where the lesion cannot be reliably measured for reasons other than its size (e.g., 
borders of the lesion are confounded by neighboring anatomical structures), no measurement 
should be entered and the lesion cannot be evaluated.
2.4.1.2
Nodal lesions
A nodal lesion less than 10 mm in size by short axis is considered normal. Lymph nodes are not 
expected to disappear completely, so a “non-zero size” will always persist.

Novartis

Measurements of nodal target lesions that become 5 mm or less in short axis are likely to be 
non-reproducible. Therefore, it is recommended to report a default value of 5 mm, instead of 
the actual measurement. This default value is derived from the 5 mm CT slice thickness (but 
should not be changed with varying CT slice thickness).Actual measurement should be given 
for all lesions larger than 5 mm in short axis irrespective of slice thickness/reconstruction 
interval.
However, once a target nodal lesion shrinks to less than 10 mm in its short axis, it will be 
considered normal for response purpose determination. The lymph node measurements will 
continue to be recorded to allow the values to be included in the sum of diameters for target 
lesions, which may be required subsequently for response determination.
2.4.2 Determination of target lesion response
Table 2-1
Response criteria for target lesions
Response Criteria
Evaluation of target lesions
Complete Response (CR):
Disappearance of all non-nodal target lesions. In addition, any pathological lymph 
nodes assigned as target lesions must have a reduction in short axis to < 10 mm 1
Partial Response (PR):
At least a 30% decrease in the sum of diameter of all target lesions, taking as 
reference the baseline sum of diameters.
Progressive Disease (PD):
At least a 20% increase in the sum of diameter of all measured target lesions, taking 
as reference the smallest sum of diameter of all target lesions recorded at or after 
baseline. In addition to the relative increase of 20%, the sum must also demonstrate 
an absolute increase of at least 5 mm 2.
Stable Disease (SD):
Neither sufficient shrinkage to qualify for PR or CR nor an increase in lesions which 
would qualify for PD.
Unknown (UNK)
Progression has not been documented and one or more target lesions have not been 
assessed or have been assessed using a different method than baseline.3
1.
SOD for CR may not be zero when nodal lesions are part of target lesions
2.
Following an initial CR, a PD cannot be assigned if all non-nodal target lesions are still not present and all 
nodal lesions are <10 mm in size. In this case, the target lesion response is CR
3.
In exceptional circumstances an UNK response due to change in method could be over-ruled by the 
investigator or central reviewer using expert judgment based on the available information (see Notes on target 
lesion response and methodology change in Section 2.2).
Notes on target lesion response
Reappearance of lesions: If the lesion appears at the same anatomical location where a target 
lesion had previously disappeared, it is advised that the time point of lesion disappearance (i.e., 
the “0 mm” recording) be re-evaluated to make sure that the lesion was not actually present 
and/or not visualized for technical reasons in this previous assessment. If it is not possible to 
change the 0 value, then the investigator/radiologist has to decide between the following 
possibilities:
The lesion is a new lesion, in which case the overall tumor assessment will be considered 
as progressive disease
The lesion is clearly a reappearance of a previously disappeared lesion, in which case the 
size of the lesion has to be entered in the CRF and the tumor assessment will remain based 
on the sum of tumor measurements as presented in Table 2-1 above (i.e., a PD will be 
determined if there is at least 20% increase in the sum of diameters of all measured target 

Novartis

Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
lesions, taking as reference the smallest sum of diameters of all target lesions recorded at or 
after baseline with at least 5 mm increase in the absolute sum of the diameters). Proper 
documentation should be available to support this decision. This applies to patients who 
have not achieved target response of CR. For patients who have achieved CR, please refer 
to last bullet in this section.
For those patients who have only one target lesion at baseline, the reappearance of the 
target lesion which disappeared previously, even if still small, is considered a PD.
Missing measurements: In cases where measurements are missing for one or more target 
lesions it is sometimes still possible to assign PD based on the measurements of the 
remaining lesions. For example, if the sum of diameters for 5 target lesions at baseline is 
100 mm at baseline and the sum of diameters for 3 of those lesions at a post-baseline visit 
is 140 mm (with data for 2 other lesions missing) then a PD should be assigned. However, 
in other cases where a PD cannot definitely be attributed, the target lesion response would 
be UNK.
Nodal lesion decrease to normal size: When nodal disease is included in the sum of target 
lesions and the nodes decrease to “normal” size they should still have a measurement 
recorded on scans. This measurement should be reported even when the nodes are normal 
in order not to overstate progression should it be based on increase in the size of nodes.
Lesions split: In some circumstances, disease that is measurable as a target lesion at 
baseline and appears to be one mass can split to become two or more smaller sub-lesions. 
When this occurs, the diameters (long axis - non-nodal lesion, short axis - nodal lesions) of 
the two split lesions should be added together and the sum recorded in the diameter field on 
the case report form under the original lesion number. This value will be included in the 
sum of diameters when deriving target lesion response. The individual split lesions will not 
be considered as new lesions, and will not automatically trigger a PD designation.
Lesions coalesced: Conversely, it is also possible that two or more lesions which were 
distinctly separate at baseline become confluent at subsequent visits. When this occurs a 
plane between the original lesions may be maintained that would aid in obtaining diameter 
measurements of each individual lesion. If the lesions have truly coalesced such that they 
are no longer separable, the maximal diameters (long axis - non-nodal lesion, short axis -
nodal lesions) of the “merged lesion” should be used when calculating the sum of 
diameters for target lesions. On the case report form, the diameter of the “merged lesion” 
should be recorded for the size of one of the original lesions while a size of “0”mm should 
be entered for the remaining lesion numbers which have coalesced.

The measurements for nodal lesions, even if less than 10 mm in size, will contribute to 
the calculation of target lesion response in the usual way with slight modifications.

Since lesions less than 10 mm are considered normal, a CR for target lesion response 
should be assigned when all nodal target lesions shrink to less than 10 mm and all non-
nodal target lesions have disappeared.

Once a CR target lesion response has been assigned a CR will continue to be appropriate 
(in the absence of missing data) until progression of target lesions.

Following a CR, a PD can subsequently only be assigned for target lesion response if 
either a non-nodal target lesion “reappears” or if any single nodal lesion is at least 10 mm 

Novartis
Confidential

Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
and there is at least 20% increase in sum of the diameters of all nodal target lesions 
relative to nadir with at least 5 mm increase in the absolute sum of the diameters. 

A change in method for the evaluation of one or more lesions will usually lead to an UNK 
target lesion response unless there is progression indicated by the remaining lesions which 
have been evaluated by the same method. In exceptional circumstances an investigator or 
central reviewer might over-rule this assignment to put a non-UNK response using expert 
judgment based on the available information. E.g. a change to a more sensitive method 
might indicate some tumor shrinkage of target lesions and definitely rule out progression 
in which case the investigator might assign an SD target lesion response; however, this 
should be done with caution and conservatively as the response categories have well 
defined criteria.

Unequivocal progression of existing non-target lesions.1
Non-CR/Non-PD:
Neither CR nor PD
Unknown (UNK)
Progression has not been documented and one or more non-target lesions have 
not been assessed or have been assessed using a different method than baseline2.
1.
The assignment of PD solely based on change in non-target lesions in light of target lesion response of CR, 
PR or SD should be exceptional. In such circumstances, the opinion of the investigator or central reviewer 
does prevail..
2.
It is recommended that the investigator and/or central reviewer should use expert judgment to assign a Non-
UNK response wherever possible (see notes section for more details)
Notes on non-target lesion response

The investigator and/or central reviewer can use expert judgment to assign a non-UNK 
response wherever possible, even where lesions have not been fully assessed or a different 
method has been used. In many of these situations it may still be possible to identify 
equivocal progression (PD) or definitively rule this out (non-CR/Non-PD) based on the 
available information. In the specific case where a more sensitive method has been used 
indicating the absence of any non-target lesions, a CR response can also be assigned.

The response for non-target lesions is CR only if all non-target non-nodal lesions which 
were evaluated at baseline are now all absent and with all non-target nodal lesions 
returned to normal size (i.e. < 10 mm). If any of the non-target lesions are still present, or 
there are any abnormal nodal lesions (i.e. 10 mm) the response can only be ‘Non-
CR/Non-PD’ unless there is unequivocal progression of the non-target lesions (in which 
case response is PD) or it is not possible to determine whether there is unequivocal 
progression (in which case response is UNK).

Unequivocal progression: To achieve “unequivocal progression” on the basis of non-target 
disease there must be an overall level of substantial worsening in non-target disease such 
that, even in presence of CR, PR or SD in target disease, the overall tumor burden has 
increased sufficiently to merit discontinuation of therapy. A modest “increase” in the size 

Novartis
Confidential
Page 134
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
of one or more non-target lesions is usually not sufficient to qualify for unequivocal 
progression status. The designation of overall progression solely on the basis of change in 
non-target disease in the face of CR, PR or SD of target disease is therefore expected to be 
rare. In order for a PD to be assigned on the basis of non-target lesions, the increase in the 
extent of the disease must be substantial even in cases where there is no measurable 
disease at baseline. If there is unequivocal progression of non-target lesion(s), then at least 
one of the non-target lesions must be assigned a status of “Worsened”. Where possible, 
similar rules to those described in Section 2.4.2 for assigning PD following a CR for the 
non-target lesion response in the presence of non-target lesions nodal lesions should be 
applied.
2.4.4 New lesions
The appearance of a new lesion is always associated with Progressive Disease (PD) and has to 
be recorded as a new lesion in the New Lesion CRF page.

If a new lesion is equivocal, for example because of its small size, continued therapy and 
follow-up evaluation will clarify if it represents truly new disease. If repeat scans confirm 
there is definitely a new lesion, then progression should be declared using the date of the 
first observation of the lesion

If new disease is observed in a region which was not scanned at baseline or where the 
particular baseline scan is not available for some reason, then this should be considered as 
a PD. The one exception to this is when there are no baseline scans at all available for a 
patient in which case the response should be UNK, as for any of this patient's assessment 
(see Section 2.5).

A lymph node is considered as a “new lesion” and therefore, indicative of progressive 
disease if the short axis increases in size to 10 mm for the first time in the study plus 5 
mm absolute increase.
FDG-PET: can complement CT scans in assessing progression (particularly possible for 
‘new’ disease). See Section 2.2.
2.5
Evaluation of overall lesion response
The evaluation of overall lesion response at each assessment is a composite of the target lesion 
response, non-target lesion response and presence of new lesions as shown below in Table 2-3.

This overall lesion response also applies when there are no non-target lesions identified at baseline.
2.
Once confirmed PR was achieved, all these assessments are considered PR.
3.
As defined in Section 2.4.
If there are no baseline scans available at all, then the overall lesion response at each assessment 
should be considered Unknown (UNK).
In some circumstances it may be difficult to distinguish residual disease from normal tissue. 
When the evaluation of complete response depends on this determination, it is recommended 
that the residual lesion be investigated (fine needle aspirate/biopsy) to confirm the CR.

Efficacy definitions
The following definitions primarily relate to patients who have measurable disease at baseline. 
Section 3.2.8 outlines the special considerations that need to be given to patients with no 
measurable disease at baseline in order to apply the same concepts.
3.1
Best overall response
The best overall response is the best response recorded from the start of the treatment until 
disease progression/recurrence (taking as reference for PD the smallest measurements recorded 
since the treatment started). In general, the patient's best response assignment will depend on 
the achievement of both measurement and confirmation criteria.
The best overall response will usually be determined from response assessments undertaken 
while on treatment. However, if any assessments occur after treatment withdrawal the protocol 
should specifically describe if these will be included in the determination of best overall 
response and/or whether these additional assessments will be required for sensitivity or 
supportive analyses. As a default, any assessments taken more than 30 days after the last dose 
of study treatment will not be included in the best overall response derivation. If any alternative 
cancer therapy is taken while on study any subsequent assessments would ordinarily be 
excluded from the best overall response determination. If response assessments taken after 
withdrawal from study treatment and/or alternative therapy are to be included in the main 
endpoint determination, then this should be described and justified in the protocol.

Where a study requires confirmation of response (PR or CR), changes in tumor measurements 
must be confirmed by repeat assessments that should be performed not less than 4 weeks after 
the criteria for response are first met.
Longer intervals may also be appropriate. However, this must be clearly stated in the protocol. 
The main goal of confirmation of objective response is to avoid overestimating the response 
rate observed. In cases where confirmation of response is not feasible, it should be made clear 
when reporting the outcome of such studies that the responses are not confirmed.

For non-randomized trials where response is the primary endpoint, confirmation is needed.

For trials intended to support accelerated approval, confirmation is needed

For all other trials, confirmation of response may be considered optional.
The best overall response for each patient is determined from the sequence of overall (lesion) 
responses according to the following rules:

CR = at least two determinations of CR at least 4 weeks apart before progression where 
confirmation required or one determination of CR prior to progression where confirmation 
not required

PR = at least two determinations of PR or better at least 4 weeks apart before progression 
(and not qualifying for a CR) where confirmation required or one determination of PR 
prior to progression where confirmation not required

SD = at least one SD assessment (or better) > 6 weeks after randomization/start of 
treatment (and not qualifying for CR or PR).

PD = progression 12 weeks after randomization/ start of treatment (and not qualifying 
for CR, PR or SD).

UNK = all other cases (i.e. not qualifying for confirmed CR or PR and without SD after 
more than 6 weeks or early progression within the first 12 weeks)
The time durations specified in the SD/PD/UNK definitions above are defaults based on a 6 
week tumor assessment frequency. However these may be modified for specific indications 
which are more or less aggressive. In addition, it is envisaged that the time duration may also 
take into account assessment windows. E.g. if the assessment occurs every 6 weeks with a time 
window of +/- 7 days, a BOR of SD would require a SD or better response longer than 5 weeks 
after randomization/start of treatment.
Overall lesion responses of CR must stay the same until progression sets in, with the exception 
of a UNK status. A patient who had a CR cannot subsequently have a lower status other than a 
PD, e.g. PR or SD, as this would imply a progression based on one or more lesions reappearing, 
in which case the status would become a PD.
Once an overall lesion response of PR is observed (which may have to be a confirmed PR 
depending on the study) this assignment must stay the same or improve over time until 
progression sets in, with the exception of an UNK status. However, in studies where 
confirmation of response is required, if a patient has a single PR (30% reduction of tumor 
burden compared to baseline) at one assessment, followed by a <30% reduction from baseline 
at the next assessment (but not 20% increase from previous smallest sum), the objective status 
at that assessment should be SD. Once a confirmed PR was seen, the overall lesion response 
should be considered PR (or UNK) until progression is documented or the lesions totally

disappear in which case a CR assignment is applicable. In studies where confirmation of 
response is not required after a single PR the overall lesion response should still be considered 
PR (or UNK) until progression is documented or the lesion totally disappears in which case a 
CR assignment is applicable.
Example: In a case where confirmation of response is required the sum of lesion diameters is 
200 mm at baseline and then 140 mm - 150 mm - 140 mm - 160 mm - 160 mm at the subsequent 
visits. Assuming that non-target lesions did not progress, the overall lesion response would be 
PR - SD - PR - PR - PR. The second assessment with 140 mm confirms the PR for this patient. 
All subsequent assessments are considered PR even if tumor measurements decrease only by 
20% compared to baseline (200 mm to 160 mm) at the following assessments.
If the patient progressed but continues study treatment, further assessments are not considered 
for the determination of best overall response.
Note: these cases may be described as a separate finding in the CSR but not included in the 
overall response or disease control rates.
The best overall response for a patient is always calculated, based on the sequence of overall 
lesion responses. However, the overall lesion response at a given assessment may be provided 
from different sources:

Investigator overall lesion response

Central Blinded Review overall lesion response

Novartis calculated overall lesion response (based on measurements from either 
Investigator or Central Review)
The primary analysis of the best overall response will be based on the sequence of 
investigator/central blinded review/calculated (investigator)/calculated (central) overall lesion 
responses.
Based on the patients’ best overall response during the study, the following rates are then 
calculated:
Overall response rate (ORR) is the proportion of patients with a best overall response of CR 
or PR. This is also referred to as ‘Objective response rate’ in some protocols or publications.
Disease control rate (DCR) is the proportion of patients with a best overall response of CR or 
PR or SD. The objective of this endpoint is to summarize patients with signs of “activity” 
defined as either shrinkage of tumor (regardless of duration) or slowing down of tumor growth. 
Clinical benefit rate (CBR) is the proportion of patients with a best overall response of CR or 
PR , or an overall lesion response of SD or Non-CR/Non-PD which lasts for a minimum time 
duration (with a default of at least 24 weeks in breast cancer studies). This endpoint measures 
signs of activity taking into account duration of disease stabilization.
Another approach is to summarize the progression rate at a certain time point after baseline. In 
this case, the following definition is used:
Early progression rate (EPR) is the proportion of patients with progressive disease within 
8 weeks of the start of treatment.

The protocol should define populations for which these will be calculated. The timepoint for 
EPR is study specific. EPR is used for the multinomial designs of Dent and Zee (2001) and 
counts all patients who at the specified assessment (in this example the assessment would be at 
8 weeks ± window) do not have an overall lesion response of SD, PR or CR. Patients with an 
unknown (UNK) assessment at that time point and no PD before, will not be counted as early 
progressors in the analysis but may be included in the denominator of the EPR rate, depending 
on the analysis population used. Similarly when examining overall response and disease control, 
patients with a best overall response assessment of unknown (UNK) will not be regarded as 
“responders” but may be included in the denominator for ORR and DCR calculation depending 
on the analysis population (e.g. populations based on an ITT approach).
3.2
Time to event variables
3.2.1 Progression-free survival
Usually in all Oncology studies, patients are followed for tumor progression after 
discontinuation of study medication for reasons other than progression or death. If this is not 
used, e.g. in Phase I or II studies, this should be clearly stated in the protocol. Note that 
randomized trials (preferably blinded) are recommended where PFS is to be the primary 
endpoint.
Progression-free survival (PFS) is the time from date of randomization/start of treatment to 
the date of event defined as the first documented progression or death due to any cause. If a 
patient has not had an event, progression-free survival is censored at the date of last adequate 
tumor assessment.
PFS rate at x weeks is an additional measure used to quantify PFS endpoint. It is recommended 
that a Kaplan Meier estimate is used to assess this endpoint. 
3.2.2 Overall survival
All patients should be followed until death or until patient has had adequate follow-up time as 
specified in the protocol whichever comes first. The follow-up data should contain the date the 
patient was last seen alive / last known date patient alive, the date of death and the reason of 
death (“Study indication” or “Other”).
Overall survival (OS) is defined as the time from date of randomization/start of treatment to 
date of death due to any cause. If a patient is not known to have died, survival will be censored 
at the date of last known date patient alive.
3.2.3 Time to progression
Some studies might consider only death related to underlying cancer as an event which indicates 
progression. In this case the variable “Time to progression” might be used. TTP is defined as 
PFS except for death unrelated to underlying cancer.
Time to progression (TTP) is the time from date of randomization/start of treatment to the 
date of event defined as the first documented progression or death due to underlying cancer. If 
a patient has not had an event, time to progression is censored at the date of last adequate tumor 
assessment.

3.2.4 PFS2
A recent EMA guidance (EMA 2012) recommends a substitute end point intermediate to PFS 
and OS called PFS2, a surrogate for OS when OS cannot be measured reliably, which assesses 
the impact of the experimental therapy on next-line treatment. The main purpose of this 
endpoint is to assess long term maintenance strategies, particularly of resensitizing agents and 
where it is necessary to examine the overall “field of influence”.
PFS2, which could be termed PFS deferred, PFS delayed, tandem PFS, or PFS version 2.0, is 
the time from date of randomization/start of treatment to the date of event defined as the first 
documented progression on next-line treatment or death from any cause. The censoring rules 
for this endpoint will incorporate the same principles as those considered for PFS in this 
document, and in addition may involve other considerations which will need to be detailed in 
the protocol.
Please note that data collection for the PFS2 is limited to the date of progression and not specific 
read of the tumor assessments.
It is strongly recommended that the teams consult regulatory agencies for scientific advice given 
the limited experience with the use of this endpoint in regulatory setting in light of 
methodological issues w.r.t. censoring foreseen.
3.2.5 Time to treatment failure
This endpoint is often appropriate in studies of advanced disease where early discontinuation is 
typically related to intolerance of the study drug. In some protocols, time to treatment failure 
may be considered as a sensitivity analysis for time to progression. The list of discontinuation 
reasons to be considered or not as treatment failure may be adapted according to the specificities 
of the study or the disease.
Time to treatment failure (TTF) is the time from date of randomization/start of treatment to 
the earliest of date of progression, date of death due to any cause, or date of discontinuation due 
to reasons other than ‘Protocol violation’ or ‘Administrative problems’. The time to treatment 
failure for patients who did not experience treatment failure will be censored at last adequate 
tumor assessment.
3.2.6 Duration of response
The analysis of the following variables should be performed with much caution when restricted 
to responders since treatment bias could have been introduced. There have been reports where 
a treatment with a significantly higher response rate had a significantly shorter duration of 
response but where this probably primarily reflected selection bias which is explained as 
follows: It is postulated that there are two groups of patients: a good risk group and a poor risk 
group. Good risk patients tend to get into response readily (and relatively quickly) and tend to 
remain in response after they have a response. Poor risk patients tend to be difficult to achieve 
a response, may have a longer time to respond, and tend to relapse quickly when they do respond. 
Potent agents induce a response in both good risk and poor risk patients. Less potent agents 
induce a response mainly in good risk patients only. This is described in more detail by Morgan 
(1988).

Protocol No. CPDR001E2201
It is recommended that an analysis of all patients (both responders and non-responders) be 
performed whether or not a “responders only” descriptive analysis is presented. An analysis of 
responders should only be performed to provide descriptive statistics and even then interpreted 
with caution by evaluating the results in the context of the observed response rates... If an 
inferential comparison between treatments is required this should only be performed on all 
patients (i.e. not restricting to “responders” only) using appropriate statistical methods such as 
the techniques described in Ellis et al (2008). It should also be stated in the protocol if duration 
of response is to be calculated in addition for unconfirmed response.
For summary statistics on “responders” only the following definitions are appropriate. (Specific 
definitions for an all-patient analysis of these endpoints are not appropriate since the status of 
patients throughout the study is usually taken into account in the analysis).
Duration of overall response (CR or PR): For patients with a CR or PR (which may have to 
be confirmed the start date is the date of first documented response (CR or PR) and the end date 
and censoring is defined the same as that for time to progression.
The following two durations might be calculated in addition for a large Phase III study in which 
a reasonable number of responders is seen.
Duration of overall complete response (CR): For patients with a CR (which may have to be 
confirmed) the start date is the date of first documented CR and the end date and censoring is 
defined the same as that for time to progression.
Duration of stable disease (CR/PR/SD): For patients with a CR or PR (which may have to be 
confirmed) or SD the start and end date as well as censoring is defined the same as that for time 
to progression.
3.2.7 Time to response
Time to overall response (CR or PR) is the time between date of randomization/start of 
treatment until first documented response (CR or PR). The response may need to be confirmed 
depending on the type of study and its importance. Where the response needs to be confirmed 
then time to response is the time to the first CR or PR observed.
Although an analysis on the full population is preferred a descriptive analysis may be performed 
on the “responders” subset only, in which case the results should be interpreted with caution 
and in the context of the overall response rates, since the same kind of selection bias may be 
introduced as described for duration of response in Section 3.2.5. It is recommended that an 
analysis of all patients (both responders and non-responders) be performed whether or not a 
“responders only” descriptive analysis is presented. Where an inferential statistical comparison 
is required, then all patients should definitely be included in the analysis to ensure the statistical 
test is valid. For analysis including all patients, patients who did not achieve a response (which 
may have to be a confirmed response) will be censored using one of the following options.

at maximum follow-up (i.e. FPFV to LPLV used for the analysis) for patients who had a 
PFS event (i.e. progressed or died due to any cause). In this case the PFS event is the 
worst possible outcome as it means the patient cannot subsequently respond. Since the 
statistical analysis usually makes use of the ranking of times to response it is sufficient to 

Novartis

Page 141
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
assign the worst possible censoring time which could be observed in the study which is 
equal to the maximum follow-up time (i.e. time from FPFV to LPLV)

at last adequate tumor assessment date otherwise. In this case patients have not yet 
progressed so they theoretically still have a chance of responding
Time to overall complete response (CR) is the time between dates of randomization/start of 
treatment until first documented CR. Similar analysis considerations including (if appropriate) 
censoring rules apply for this endpoint described for the time to overall response endpoint.
3.2.8 Definition of start and end dates for time to event variables
Assessment date
For each assessment (i.e. evaluation number), the assessment date is calculated as the latest of 
all measurement dates (e.g. X-ray, CT-scan) if the overall lesion response at that assessment is 
CR/PR/SD/UNK. Otherwise - if overall lesion response is progression - the assessment date is 
calculated as the earliest date of all measurement dates at that evaluation number.
In the calculation of the assessment date for time to event variables, any unscheduled 
assessment should be treated similarly to other evaluations.
Start dates
For all “time to event” variables, other than duration of response, the randomization/ date of 
treatment start will be used as the start date.
For the calculation of duration of response the following start date should be used:

Date of first documented response is the assessment date of the first overall lesion 
response of CR (for duration of overall complete response) or CR / PR (for duration of 
overall response) respectively, when this status is later confirmed.
End dates
The end dates which are used to calculate ‘time to event’ variables are defined as follows:

Date of death (during treatment as recorded on the treatment completion page or during 
follow-up as recorded on the study evaluation completion page or the survival follow-up 
page).

Date of progression is the first assessment date at which the overall lesion response was 
recorded as progressive disease.

Date of last adequate tumor assessment is the date the last tumor assessment with overall 
lesion response of CR, PR or SD which was made before an event or a censoring reason 
occurred. In this case the last tumor evaluation date at that assessment is used. If no post-
baseline assessments are available (before an event or a censoring reason occurred) the 
date of randomization/start of treatment is used.

Date of next scheduled assessment is the date of the last adequate tumor assessment plus 
the protocol specified time interval for assessments. This date may be used if back-dating 
is considered when the event occurred beyond the acceptable time window for the next 
tumor assessment as per protocol (see Section 3.2.8).

Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
Example (if protocol defined schedule of assessments is 3 months): tumor assessments at 
baseline - 3 months - 6 months - missing - missing - PD. Date of next scheduled assessment 
would then correspond to 9 months.

Date of discontinuation is the date of the end of treatment visit.

Date of last contact is defined as the last date the patient was known to be alive. This 
corresponds to the latest date for either the visit date, lab sample date or tumor assessment 
date. If available, the last known date patient alive from the survival follow-up page is 
used. If no survival follow-up is available, the date of discontinuation is used as last 
contact date.

Date of secondary anti-cancer therapy is defined as the start date of any additional 
(secondary) antineoplastic therapy or surgery.
3.2.9 Handling of patients with non-measurable disease only at baseline
It is possible that patients with only non-measurable disease present at baseline are entered into 
the study, either because of a protocol violation or by design (e.g. in Phase III studies with PFS 
as the primary endpoint). In such cases the handling of the response data requires special 
consideration with respect to inclusion in any analysis of endpoints based on the overall 
response evaluations.
It is recommended that any patients with only non-measurable disease at baseline should be 
included in the main (ITT) analysis of each of these endpoints.
Although the text of the definitions described in the previous sections primarily relates to 
patients with measurable disease at baseline, patients without measurable disease should also 
be incorporated in an appropriate manner. The overall response for patients with non-
measurable disease is derived slightly differently according to Table 3-1.

target disease only

In general, the non-CR/non-PD response for these patients is considered equivalent to an SD 
response in endpoint determination. In summary tables for best overall response patients with 
only non-measurable disease may be highlighted in an appropriate fashion e.g. in particular by 
displaying the specific numbers with the non-CR/non-PD category.
In considering how to incorporate data from these patients into the analysis the importance to 
each endpoint of being able to identify a PR and/or to determine the occurrence and timing of 
progression needs to be taken into account.

Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
For ORR it is recommended that the main (ITT) analysis includes data from patients with only 
non-measurable disease at baseline, handling patients with a best response of CR as “responders” 
with respect to ORR and all other patients as “non-responders”. 
For PFS, it is again recommended that the main ITT analyses on these endpoints include all 
patients with only non-measurable disease at baseline, with possible sensitivity analyses which 
exclude these particular patients. Endpoints such as PFS which are reliant on the determination 
and/or timing of progression can incorporate data from patients with only non-measurable 
disease.
3.2.10 Sensitivity analyses
This section outlines the possible event and censoring dates for progression, as well as addresses 
the issues of missing tumor assessments during the study. For instance, if one or more 
assessment visits are missed prior to the progression event, to what date should the progression 
event be assigned? And should progression event be ignored if it occurred after a long period 
of a patient being lost to follow-up? It is important that the protocol and RAP specify the 
primary analysis in detail with respect to the definition of event and censoring dates and also 
include a description of one or more sensitivity analyses to be performed.
Based on definitions outlined in Section 3.2.7, and using the draft FDA guideline on endpoints 
(Clinical Trial Endpoints for the Approval of Cancer Drugs and Biologics, April 2005) as a 
reference, the following analyses can be considered:

3.
=The rare exception to this is if the patient dies no later than the time of the second scheduled assessment 
as defined in the protocol in which case this is a PFS event at the date of death.
The primary analysis and the sensitivity analyses must be specified in the protocol. Clearly 
define if and why options (1) are not used for situations C, E and (if applicable) F.
Situations C (C1 and C2): Progression or death after one or more missing assessments: The 
primary analysis is usually using options (1) for situations C1 and C2, i.e.

(C1) taking the actual progression or death date, in the case of only one missing 
assessment.

(C2) censoring at the date of the last adequate assessment, in the case of two or more 
consecutive missing assessments.
In the case of two or missing assessments (situation C2), option (3) may be considered jointly 
with option (1) in situation C1 as sensitivity analysis. A variant of this sensitivity analysis 
consists of backdating the date of event to the next scheduled assessment as proposed with 
option (2) in situations C1 and C2.
Situation E: Treatment discontinuation due to ‘Disease progression’ without documented 
progression: By default, option (1) is used for situation E as patients without documented PD 
should be followed for progression after discontinuation of treatment. However, option (2) may 
be used as sensitivity analysis. If progression is claimed based on clinical deterioration instead 
of tumor assessment by e.g. CT-scan, option (2) may be used for indications with high early 
progression rate or difficulties to assess the tumor due to clinical deterioration.
Situation F: New cancer therapy given: the handling of this situation must be specified in 
detail in the protocol. However, option (1) (ITT) is the recommended approach; events 
documented after the initiation of new cancer therapy will be considered for the primary 
analysis i.e. progressions and deaths documented after the initiation of new cancer therapy 
would be included as events. This will require continued follow-up for progression after the 
start of the new cancer therapy. In such cases, it is recommended that an additional sensitivity 
analysis be performed by censoring at last adequate assessment prior to initiation of new cancer 
therapy.
Option (2), i.e. censoring at last adequate assessment may be used as a sensitivity analysis. If a 
high censoring rate due to start of new cancer therapy is expected, a window of approximately 
8 weeks performed after the start of new cancer therapy can be used to calculate the date of the 
event or censoring. This should be clearly specified in the analysis plan. 
In some specific settings, local treatments (e.g. radiation/surgery) may not be considered as 
cancer therapies for assessment of event/censoring in PFS/TTP/DoR analysis. For example, 

Novartis
Confidential
Page 145
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
palliative radiotherapy given in the trial for analgesic purposes or for lytic lesions at risk of 
fracture will not be considered as cancer therapy for the assessment of BOR and PFS analyses. 
The protocol should clearly state the local treatments which are not considered as antineoplastic 
therapies in the PFS/TTP/DoR analysis.
The protocol should state that tumor assessments will be performed every x weeks until 
radiological progression irrespective of initiation of new antineoplastic therapy. It is strongly 
recommended that a tumor assessment is performed before the patient is switched to a new 
cancer therapy.
Additional suggestions for sensitivity analyses
Other suggestions for additional sensitivity analyses may include analyses to check for potential 
bias in follow-up schedules for tumor assessments, e.g. by assigning the dates for censoring and 
events only at scheduled visit dates. The latter could be handled by replacing in Table 3-2 the 
“Date of last adequate assessment” by the “Date of previous scheduled assessment (from 
baseline)”, with the following definition:

Date of previous scheduled assessment (from baseline) is the date when a tumor 
assessment would have taken place, if the protocol assessment scheme was strictly 
followed from baseline, immediately before or on the date of the last adequate tumor 
assessment.
In addition, analyses could be repeated using the Investigators’ assessments of response rather 
than the calculated response. The need for these types of sensitivity analyses will depend on the 
individual requirements for the specific study and disease area and have to be specified in the 
protocol or RAP documentation.

Data handling and programming rules
The following section should be used as guidance for development of the protocol, data 
handling procedures or programming requirements (e.g. on incomplete dates).
4.1
Study/project specific decisions
For each study (or project) various issues need to be addressed and specified in the protocol or 
RAP documentation. Any deviations from protocol must be discussed and defined at the latest 
in the RAP documentation.
The proposed primary analysis and potential sensitivity analyses should be discussed and 
agreed with the health authorities and documented in the protocol (or at the latest in the RAP 
documentation before database lock).
4.2
End of treatment phase completion
Patients may voluntarily withdraw from the study treatment or may be taken off the study 
treatment at the discretion of the investigator at any time. For patients who are lost to follow-
up, the investigator or designee should show "due diligence" by documenting in the source 
documents steps taken to contact the patient, e.g., dates of telephone calls, registered letters, etc.

Novartis

Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
The end of treatment visit and its associated assessments should occur within 7 days of the last 
study treatment. 
Patients may discontinue study treatment for any of the following reasons:

Adverse event(s)

Lost to follow-up

Physician decision

Pregnancy

Protocol deviation

Technical problems

Subject/guardian decision

Progressive disease

Study terminated by the sponsor

Non-compliant with study treatment

No longer requires treatment

Treatment duration completed as per protocol (optional, to be used if only a fixed number 
of cycles is given)
Death is a reason which “must” lead to discontinuation of patient from trial. 
4.3
End of post-treatment follow-up (study phase completion)
End of post-treatment follow-up visit will be completed after discontinuation of study treatment 
and post-treatment evaluations but prior to collecting survival follow-up.
Patients may provide study phase completion information for one of the following reasons:

Adverse event

Lost to follow-up

Physician decision

Pregnancy

Protocol deviation

Technical problems

Subject/guardian decision

Death

Progressive disease


4.4
Medical validation of programmed overall lesion response
In order to be as objective as possible the RECIST programmed calculated response assessment 
is very strict regarding measurement methods (i.e. any assessment with more or less sensitive 
method than the one used to assess the lesion at baseline is considered UNK) and not available 
evaluations (i.e. if any target or non-target lesion was not evaluated the whole overall lesion 
response is UNK unless remaining lesions qualified for PD). This contrasts with the slightly 

Novartis
Confidential
Page 147
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
more flexible guidance given to local investigators (and to the central reviewers) to use expert 
judgment in determining response in these type of situations, and therefore as a consequence 
discrepancies between the different sources of response assessment often arise. To ensure the 
quality of response assessments from the local site and/or the central reviewer, the responses 
may be re-evaluated by clinicians (based on local investigator data recorded in eCRF or based 
on central reviewer data entered in the database) at Novartis or external experts. In addition, 
data review reports will be available to identify assessments for which the investigators’ or 
central reader’s opinion does not match the programmed calculated response based on RECIST 
criteria. This may be queried for clarification. However, the investigator or central reader’s 
response assessment will never be overruled.
If Novartis elect to invalidate an overall lesion response as evaluated by the investigator or 
central reader upon internal or external review of the data, the calculated overall lesion response 
at that specific assessment is to be kept in a dataset. This must be clearly documented in the 
RAP documentation and agreed before database lock. This dataset should be created and stored 
as part of the ‘raw’ data.
Any discontinuation due to ‘Disease progression’ without documentation of progression by 
RECIST criteria should be carefully reviewed. Only patients with documented deterioration of 
symptoms indicative of progression of disease should have this reason for discontinuation of 
treatment or study evaluation.
4.5
Programming rules
The following should be used for programming of efficacy results:
4.5.1 Calculation of ‘time to event’ variables
Time to event = end date - start date + 1 (in days)
When no post-baseline tumor assessments are available, the date of randomization/start of 
treatment will be used as end date (duration = 1 day) when time is to be censored at last tumor 
assessment, i.e. time to event variables can never be negative.
4.5.2 Incomplete assessment dates
All investigation dates (e.g. X-ray, CT scan) must be completed with day, month and year.
If one or more investigation dates are incomplete but other investigation dates are available, 
this/these incomplete date(s) are not considered for calculation of the assessment date (and 
assessment date is calculated as outlined in Section 3.2.7). If all measurement dates have no day 
recorded, the 1st of the month is used.
If the month is not completed, for any of the investigations, the respective assessment will be 
considered to be at the date which is exactly between previous and following assessment. If a 
previous and following assessment is not available, this assessment will not be used for any 
calculation.

4.5.3 Incomplete dates for last known date patient alive or death
All dates must be completed with day, month and year. If the day is missing, the 15th of the 
month will be used for incomplete death dates or dates of last contact.
4.5.4 Non-target lesion response
If no non-target lesions are identified at baseline (and therefore not followed throughout the 
study), the non-target lesion response at each assessment will be considered ‘not applicable 
(NA)’.
4.5.5 Study/project specific programming
The standard analysis programs need to be adapted for each study/project.
4.5.6 Censoring reason
In order to summarize the various reasons for censoring, the following categories will be 
calculated for each time to event variable based on the treatment completion page, the study 
evaluation completion page and the survival page.
For survival the following censoring reasons are possible:

Alive

Lost to follow-up
For PFS and TTP (and therefore duration of responses) the following censoring reasons are 
possible:

Ongoing without event

Lost to follow-up

Withdrew consent

Adequate assessment no longer available*

Event documented after two or more missing tumor assessments (optional, see Table 3-2)

Death due to reason other than underlying cancer (only used for TTP and duration of 
response)

Initiation of new anti-cancer therapy  
* Adequate assessment is defined in Section 3.2.7. This reason is applicable when adequate 
evaluations are missing for a specified period prior to data cut-off (or prior to any other 
censoring reason) corresponding to the unavailability of two or more planned tumor 
assessments prior to the cut-off date. The following clarifications concerning this reason should 
also be noted:

This may be when there has been a definite decision to stop evaluation (e.g. 
reason=“sponsor decision” on study evaluation completion page), when patients are not 
followed for progression after treatment completion or when only UNK assessments are 
available just prior to data cut-off).

The reason "Adequate assessment no longer available" also prevails in situations when 
another censoring reason (e.g. withdrawal of consent, loss to follow-up or alternative anti-

cancer therapy) has occurred more than the specified period following the last adequate 
assessment.

This reason will also be used to censor in case of no baseline assessment.

Introduction
Immune-related response criteria have been developed to better assess the patterns of response 
and progression with cancer immunotherapies (Wolchok et al. 2009, Nishino et al. 2013, 2014). 
This document outlines the working definitions and rules for immune-related response criteria 
based on RECIST 1.1 (irRECIST).
For definition of measurable and non-measurable lesions, methods of tumor measurement, 
baseline documentation of target and non-target lesions, eligibility based on measurable disease, 
follow-up evaluation of lesions, etc., refer to RECIST 1.1 (Appendix 1).
2
Baseline assessment of tumor burden
All measurable lesions (nodal and non-nodal) up to a maximum of five lesions in total (and a 
maximum of two lesions per organ), representative of all involved organs should be identified 
as target lesions and recorded and measured at baseline. All other lesions present at baseline 
will be considered as non-target lesions. Together these present the baseline tumor burden.
The Total Measurable Tumor Burden (TMTB) at baseline is defined as the sum of diameters 
(SOD) of all target lesions.
3
Post-baseline assessment of tumor burden
Target, non-target and new lesions (measurable and non-measurable) will be evaluated at each 
post-baseline assessment. Target and non-target lesions identified at baseline will continue to 
be followed as target and non-target lesions, respectively. New measurable  lesions will be 
included in the TMTB which is defined as the SOD of target lesions and the new measurable 
lesions for post-baseline assessments. The nadir TMTB at a given time point ‘n’ is defined as 
the smallest TMTB observed for a given patient up to, but excluding that time point (i.e. from 
baseline to timepoint ‘n-1’).
A new measurable lesion is a newly observed lesion that was not present at baseline tumor 
assessment and is measurable as per RECIST 1.1. Overall a maximum of five new measurable 
lesions (nodal or non-nodal) can be included in the TMTB with a maximum of two new 
measurable lesions per organ. If there are more than 5 new measurable lesions in total, or more 
than 2 in the same organ at a post-baseline tumor evaluation, then the largest and most 
reproducible new measurable lesions should be included in TMTB. Note that two new 
measurable lesions per organ can be included in the TMTB irrespective of whether baseline 
target lesions were already identified in that organ or not. All other new lesions will be included 
in the overall tumor burden assessment as new non-measurable lesions.
A new measurable lesion included in the TMTB must always be included in TMTB for all 
subsequent tumor assessments. A new non-measurable lesion will always be followed as a non-
measurable lesion at subsequent tumor assessments even if it becomes measurable.
The overall tumor burden (OTB) includes the TMTB, non-target lesions and new non-
measurable lesions.

Overall response assessment
An overall response assessment should occur at each post-baseline assessment, and will take 
into account the evaluation of the TMTB together with the status of non-target lesions and new 
non-measurable lesions.
Baseline non-target lesions
The response of non-target lesions primarily contributes to the overall response assessment of 
complete response (irCR), with persisting non-target lesions preventing irCR. Only a clear and 
unequivocal worsening of non-target lesions alone (i.e. worsening of the tumor burden which 
is substantial enough leading to discontinuation or change of therapy), would be indicative of 
irPD.
New lesions
A new lesion does not automatically indicate progressive disease. 
New measurable lesions are added to the SOD to obtain the TMTB as described in Section 
14.2.3 at each post-baseline tumor evaluation. All new lesions not selected as new measurable 
lesions for obtaining TMTB are considered as new non-measurable lesions and are followed 
qualitatively. Only an unequivocal progression of new non-measurable lesions (i.e. worsening 
of the overall tumor burden which is substantial enough leading to discontinuation or change of 
therapy) would be indicative of irPD. Persisting new non-measurable lesions prevent irCR.
Note: The designation of overall irPD solely on the basis of change in non-target disease or new 
non-measurable lesions in the face of no progression based on TMTB is expected to be 
uncommon.
4.1
Definition of response categories
The response categories at each post-baseline assessment are defined as follows:

Immune related Complete Response (irCR): Complete disappearance of all measurable 
and non-measurable lesions. In addition, any pathological lymph nodes must have a 
reduction in short axis to < 10 mm. 

TMTB may be greater than zero at the time of CR, if nodal lesions are included in 
TMTB. 

In some circumstances it may be difficult to distinguish residual disease from normal 
tissue. When the evaluation of complete response depends on this determination, it is 
recommended that the residual lesion be investigated (fine needle aspirate/biopsy) to 
determine the irCR.

Immune related Partial Response (irPR): At least 30% decrease in the TMTB compared 
to baseline and not qualifying for irPD or irCR 

Immune related Progressive Disease (irPD): At least a 20% increase in the TMTB 
compared to nadir. In addition to the relative increase of 20%, TMTB must also demonstrate 
an absolute increase of at least 5 mm. An unequivocal progression of existing non-target or 
new non-measurable lesions may also lead to irPD.

Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201

Immune related Stable Disease (irSD): Neither a sufficient shrinkage to qualify for irPR 
or irCR, nor an increase in lesions, or a clear and unequivocal progression of existing non-
target or new non-measurable lesions that would qualify for irPD. 

Unknown for irRECIST (irUNK): Progression has not been documented and one or 
more target lesions or new measurable lesions observed at earlier assessment have not been 
assessed, or have been assessed using a significantly different method (i.e. prevents 
reasonable comparison to the prior assessments) than baseline (target lesions) or assessment 
of first occurrence (new measurable lesions). Note that if non-target or new non-measurable 
lesions have not been assessed at any given post-baseline time-point, then this will not lead 
to overall response irUNK. If the evaluation of any non-target lesion or new non-measurable 
lesion is not done, and all target lesions and other non-target lesions disappeared, irCR 
cannot be determined and overall response must be “irPR”.

4.1.1 Notes on lesion response
Reappearance of lesions
If the lesion reappears at the same anatomical location where a target lesion had previously 
disappeared, it is advised that the time point of lesion disappearance (i.e., the “0 mm” recording) 
be re-evaluated to make sure that the lesion was not actually present and/or not visualized for 
technical reasons in this previous assessment. If the previous disappearance of the lesion is 
confirmed, then the investigator/radiologist has to decide between the following possibilities:

The lesion is a new lesion, in which case the overall tumor assessment should consider 
this appropriately either as a new measurable or new non-measurable lesion.

The lesion is clearly a reappearance of a previously disappeared lesion, in which case the 
size of the lesion has to be entered in the CRF and the tumor assessment will remain based 
on the sum of tumor measurements as presented in the Table above. This applies to 
patients who have not achieved target response of irCR. For patients who have achieved 
irCR, please refer to below.
Progressive disease after complete response

Protocol No. CPDR001E2201
Similar to RECIST 1.1, following a confirmed irCR, an irPD can subsequently only be assigned 
if any one of below is observed:

Either a non-nodal target or new-measurable lesion that disappeared earlier reappears at 
the same anatomical location. 

Any single nodal lesion gets >10mm in diameter and there is at least 20% increase in sum 
of the diameters of all nodal target and nodal new-measurable lesions relative to nadir 
with at least 5 mm increase in the absolute sum of the diameters.

Unequivocal progression based on non-target and new non-measurable lesions. 
Missing measurements
In cases where measurements are missing for one or more target or new-measurable lesions it 
is sometimes still possible to assign irPD based on the measurements of the remaining lesions. 
For example, if the sum of diameters for 5 target lesions at baseline is 100 mm at baseline and 
the sum of diameters for 3 of those lesions at a post-baseline visit is 140 mm (with data for 2 
other lesions missing) then an irPD should be assigned. However, in other cases where an irPD 
cannot definitely be attributed, the target lesion response would be irUNK.
Nodal lesions

Nodal lesion decrease to normal size: When nodal disease is included in the sum of target 
lesions and the nodes decrease to “normal” size they should still have a measurement 
recorded on scans. This measurement should be reported even when the nodes are normal 
in order not to overstate progression should it be based on increase in the size of nodes.

The measurements for nodal lesions, even if less than 10 mm in size, will contribute to the 
calculation of target lesion response in the usual way with slight modifications.

Since nodal lesions less than 10 mm are considered normal, an irCR for target lesion 
response based on TMTB should be assigned when all nodal target and new-measurable 
lesions shrink to less than 10 mm and all non-nodal target lesions have disappeared.
Splitting and coalescence of lesions

Lesions split: In some circumstances, disease that is measurable as a target or new-
measurable lesion at baseline and appears to be one mass can split to become two or more 
smaller sub-lesions at subsequent assessments. When this occurs, the diameters (long axis 
- non-nodal lesion, short axis - nodal lesions) of the two split lesions should be added 
together and the sum recorded in the diameter field on the case report form under the 
original lesion number. This value will be included in the sum of diameters when deriving 
target lesion response based on TMTB. The individual split lesions will not be considered 
as new lesions.

Lesions coalesced: Conversely, it is also possible that two or more lesions which were 
distinctly separate at earlier assessment(s) become confluent at subsequent visits. When 
this occurs a plane between the original lesions may be maintained that would aid in 
obtaining diameter measurements of each individual lesion. If the lesions have truly 
coalesced such that they are no longer separable, the maximal diameters (long axis - non-
nodal lesion, short axis - nodal lesions) of the “merged lesion” should be used when 
calculating the sum of diameters for target lesions. On the case report form, the diameter 
of the “merged lesion” should be recorded for the size of one of the original lesions while

a size of “0”mm should be entered for the remaining lesion numbers which have 
coalesced.
4.2
Confirmation of response or progression
Confirmation of irCR and irPR is required by a repeat assessment at least 4 weeks after the 
initial assessment. 
Confirmation of irPD is highly recommended particularly for difficult cases (i.e. mixed 
response, early appearance of new lesions/increase in measurable tumor burden in patients with 
stable or improving general status/clinical condition) or suspected pseudo-progression/tumor 
flare provided there is no rapid clinical deterioration. The irPD is confirmed if in a repeat tumor 
assessment at least 4 weeks later meets again the irPD criteria as defined in Section 4.1.
No confirmation is required for irSD.
4.3
Determination of Best overall response
For best overall response (BOR), in general all the details as specified in the RECIST 1.1 
appendix Section 14.1.3.1 will apply unless stated otherwise below or in the study protocol.
The best overall response for each patient is determined from the sequence of overall responses 
according to the following rules:

irCR = at least two determinations of irCR at least 4 weeks apart before confirmed 
progression. Note that there should not be any tumor assessment with an overall response 
of irPD in between 

irPR = at least two determinations of irPR or better at least 4 weeks apart before 
confirmed progression (and not qualifying for irCR). Note that there should not be any 
tumor assessment with an overall response of irPD in between 

irSD = at least one irSD assessment (or better) > 6 weeks after randomization/start of 
treatment and before confirmed progression (and not qualifying for irCR or irPR). 

irPD = confirmed immune related progression or immune related progression with no 
further adequate tumor assessments £ 12 weeks after randomization/ start of treatment (and 
not qualifying for irCR, irPR or irSD) 

irUNK = all other cases (i.e. not qualifying for confirmed irCR or irPR and without irSD 
after more than 6 weeks or early progression within the first 12 weeks) 

If the next tumor assessment is inadequate with an overall response of irUNK then the next 
adequate tumor assessment will be considered for confirmation. E.g. an irCR followed by 
irUNK followed by irPR will be a confirmed irPR.
Similar to RECIST 1.1 overall lesion response of irCR or irPR, after their confirmation, will 
remain the same or improve until confirmed irPD.
5
Only non-measurable disease at baseline
For patients with only non-measurable disease at baseline, unequivocal progression of non-
target lesions (i.e. worsening of the overall tumor burden which is substantial enough leading 
to discontinuation or change of therapy) will constitute an irPD. In addition, the appearance of 
new lesions (measurable or non-measurable) consistent with unequivocal progression taking 

Novartis
Confidential
Page 155
Amended Protocol Version 03 (Clean)
Protocol No. CPDR001E2201
into account the overall disease burden will constitute an irPD. The absence of all non-target 
lesions and no new lesions will qualify for irCR. Otherwise the overall response will be 
considered as irNon-CR/Non-PD (irNCRNPD) similar to RECIST 1.1. The same rules for 
confirmation of irPD and irCR apply as specified above in Section 4.3. If any baseline non-
target lesion or a new lesions observed at an earlier post-baseline evaluation was not/could not 
be assessed at a later post-baseline tumor evaluation then the overall response will be irUNK.  
No confirmation is required for irNCRNPD. For the BOR the same definition as in Section 
14.2.4.3 applies for irCR, irPD and irUNK. For BOR of irNCRNPD the definition for irSD will 
be used.

Definition of endpoints
Immune related overall response rate (irORR) is the proportion of patients with a best 
overall response of irCR or irPR. This is also referred to as ‘Objective response rate’ in some 
protocols or publications.
Immune related disease control rate (irDCR) is the proportion of patients with a best overall 
response of irCR or irPR or irSD. Patients with BOR of irNCRNPD will also be included in 
DCR if patients with non-measurable disease at baseline are in analysis set.  
Another approach is to summarize the progression rate at a certain time point after baseline. In 
this case, the following definition is used:
Immune related early progression rate (irEPR) is the proportion of patients with immune 
related progressive disease (irPD) within 12 weeks of the start of treatment.
6.1
Time to event endpoints
6.1.1 Progression-free survival
Immune related progression-free survival
(irPFS)
is the time from date of 
randomization/start of treatment to the date of event defined as the first documented assessment 
of irPD that was then confirmed or death due to any cause. Unconfirmed irPD without further 
adequate tumor assessments will be considered as a confirmed irPD. If a patient has not had an 
event, progression-free survival is censored at the date of last adequate tumor assessment. An 
adequate tumor assessment is a tumor assessment with overall response other than irUNK. Refer 
to RECIST 1.1 appendix for additional details on censoring rules. 
6.1.2 Time to progression
Immune related time to progression (irTTP) is the time from date of randomization/start of 
treatment to the date of event defined as the first documented assessment of irPD that was then 
confirmed or death due to underlying cancer. Unconfirmed irPD without further adequate tumor 
assessments will be considered as a confirmed irPD. If a patient has not had an event, time to 
progression is censored at the date of last adequate tumor assessment. An adequate tumor 
assessment is defined as a tumor assessment with overall response other than irUNK. Refer to 
RECIST 1.1 appendix for additional details on censoring rules.

6.1.3 Time to treatment failure
Immune related time to treatment failure (irTTF)
is the time from date of 
randomization/start of treatment to the earliest of date of progression (confirmed irPD), date of 
death due to any cause, or date of discontinuation due to reasons other than ‘Protocol deviation’ 
or ‘Technical problems’. Unconfirmed irPD without further adequate tumor assessments will 
be considered as a confirmed irPD. The time to treatment failure for patients who did not 
experience treatment failure will be censored at last adequate tumor assessment. An adequate 
tumor assessment is defined as a tumor assessment with overall response other than irUNK.
6.1.4 Time to response
Immune related time to overall response (irCR or irPR) (irTTR) is the time between date 
of randomization/start of treatment until first documented response (confirmed irCR or irPR). 
Time to overall response will be censored for patients without confirmed irCR or irPR as 
described in RECIST 1.1 appendix.
6.1.5 Duration of response 
Immune related duration of overall response (irCR or irPR) (irDOR): For patients with a 
confirmed irCR or irPR the start date is the date of first documented confirmed response and 
the end date and censoring is defined the same as that for time to progression.
The following two durations might be calculated in addition for a large Phase III study in which 
a reasonable number of responders are observed.
Immune related duration of overall complete response (irCR): For patients with a 
confirmed irCR the start date is the date of first documented confirmed irCR and the end date 
and censoring is defined the same as that for time to progression.
Immune related duration of stable disease (irCR/irPR/irSD): For patients with BOR of irCR 
(confirmed) or irPR (confirmed) or irSD the start and end date as well as censoring is defined 
the same as that for time to progression.
6.1.6 Definition of start and end dates for time to event variables
