Brief Protocol Synopsis 
See Protocol Document Sections for complete details 
This is a single arm, open label phase II study of the anti-PD-L1 antibody, durvalumab, in combination with 
pemetrexed and cisplatin chemotherapy in the first-line treatment of patients with unresectable pleural 
mesothelioma. Standard chemotherapy with pemetrexed/cisplatin will be given for up to six 3-week cycles 
with the addition of concurrent durvalumab dosed at 1120 mg every 3 weeks. The first 6 patients who are 
enrolled and commence treatment will be monitored for safety of the combination. Use of carboplatin in place 
of cisplatin will be permitted for patients who are ineligible for cisplatin due to a documented contraindication 
(e.g., ototoxicity, renal function), however these patients must otherwise fulfill the eligibility criteria for the 
study. For patients who receive cisplatin, carboplatin may also be substituted after Cycle 1 for cisplatin 
related toxicity (e.g., grade 3 ototoxicity, grade 3 nausea) at the investigator’s discretion. After completion of 
Cycle 6 of concurrent therapy, patients with stable or responding disease per modified RECIST for malignant 
mesothelioma will continue on single agent durvalumab 1120 mg every 3 weeks until progression. Maximum 
duration of durvalumab treatment is 12 months starting from Cycle 1 of concurrent treatment (inclusive of 
any treatment delays or missed treatments). 
The primary endpoint of the study is overall survival (OS) as compared with historical control.

Introduction- Background and Rationale 
1.1 
Mesothelioma – Disease Overview 
Mesothelioma is a malignant tumor of mesothelial surfaces primarily arising in the thoracic 
pleura and is estimated to cause 43,000 deaths worldwide each year with over 3300 cases 
occurring annually in the United States [1, 2]. Approximately 80% of cases of mesothelioma 
are due to inflammation induced by prior asbestos exposure with a lead time from exposure 
to development of cancer of 20-30 years [1]. It is predicted that the incidence of 
mesothelioma due to previous exposure will rise significantly in many countries over the 
next two decades particularly in Europe, China, Russia and Japan [3, 4]. The median 
survival for all patients diagnosed with mesothelioma is extremely poor at 6-18 months and 
the vast majority of patients will relapse after surgical resection or present with unresectable 
disease [5, 6]. The known role of asbestos and chronic inflammation in the etiology of 
mesothelioma has led to the discovery of the pivotal role the immune system plays in the 
initiation and progression of mesothelioma [7]. Immunotherapy is one of the most promising 
avenues of clinical investigation in mesothelioma at present and several clinical trials are 
evaluating immune modulating agents [8]. 
1.2 
Background/Rationale 
1.2.1 
PD-L1 in Immune Evasion 
Immune responses directed against tumors are one of the body’s natural defenses 
against the growth and proliferation of cancer cells. However, over time and under 
pressure from immune attack, cancers develop strategies to evade immune-
mediated killing allowing them to develop unchecked. One such mechanism 
involves upregulation of surface proteins that deliver inhibitory signals to cytotoxic 
T cells. Programmed cell death ligand 1 (PD-L1) is one such protein, and is 
upregulated in a broad range of cancers with a high frequency, with up to 88% 
expression in some tumor types. In a number of these cancers, including lung [9], 
renal [10, 11, 12], pancreatic [13, 14, 15], ovarian cancer [16], and hematologic 
malignancies [17, 18] tumor cell expression of PD-L1 is associated with reduced 
survival and an unfavourable prognosis. 
Programmed cell death ligand 1 is part of a complex system of receptors and 
ligands that are involved in controlling T-cell activation. PD-L1 acts at multiple sites 
in the body to help regulate normal immune responses and is utilized by tumors to 
help evade detection and elimination by the host immune system tumor response. 
In the lymph nodes, PD-L1 on antigen-presenting cells binds to PD-1 or CD80 on 
activated T cells and delivers an inhibitory signal to the T cell [19, 20]. This results 
in reduced T-cell activation and fewer activated T cells in circulation. In the tumor 
microenvironment, PD-L1 expressed on tumor cells binds to PD-1 and CD80 on 
activated T cells reaching the tumor. This delivers an inhibitory signal to those T 
cells, preventing them from killing target cancer cells and protecting the tumor from 
immune elimination [21]. 
1.2.2 
PD-L1 is Highly Expressed in Mesothelioma 
Preclinical data suggests that one of two ligands of PD-1, programmed death-ligand 
1 (PD-L1) is highly expressed in mesothelioma tumor cells [22]. PD-L1 is a putative 
predictive marker for response to PD-L1- and PD-1-directed therapeutics in multiple 
tumor types across multiple early and late phase studies [23-25]. 
We have recently performed PD-L1 immunohistochemical (IHC) testing, using the 
murine anti-human PD-L1 monoclonal antibody 5H1, on standard formalin-fixed 
paraffin-embedded (FFPE) tissue sections of large biopsy or resection specimens 
from 25 pleural (17 epithelioid, 7 biphasic & 1 sarcomatoid) and 8 peritoneal 
mesotheliomas. Based on earlier published studies tumor cells or tumor infiltrating 

PrECOG Protocol Number: PrE0505 
Confidential 
Date: 3/19/2018 
 
11 
lymphocytes were considered positive if at least 5% exhibited membranous staining 
[23]. The mesothelioma tumor cells in the analyzed cohort demonstrated high levels 
of PD-L1 expression, 17 of 33 tumors (52%) were PD-L1 positive and high level 
expression (>50% staining) was present in 14 of 33 tumors (42%). Another group 
has recently reported similar findings from 224 patient cases analyzed 
retrospectively using the 5H1 antibody [26]. Using a 5% cutoff for positivity, 40% of 
mesothelioma tumors expressed PD-L1 (89/224). PD-L1 expression was 
associated with worse overall survival (6 months vs. 14 months, p<0.0001) even 
when adjusted for age, gender, lymphocytic infiltration and therapeutic surgery 
(p<0.0002). 
Recent analysis of gene expression suggests high levels of CD8 infiltration in 32% 
of mesotheliomas and high level PD-L1 expression in 12 of 44 tumors (27%) 
providing a further rationale for PD1/PD-L1-directed therapy in mesothelioma [27]. 
In addition recent data from a mesothelioma cohort enrolled in a phase Ib clinical 
trial of the anti-PD-1 antibody, pembrolizumab, were highly promising with 28% 
(7/25) of chemo-refractory patients have an objective response by modified 
Response Evaluation Criteria in Solid Tumors (RECIST) for mesothelioma and a 
further 48% (12/25) having prolonged stable disease [28]. This has led to a phase 
II single arm clinical trial of pembrolizumab in the second- and third-line setting [29].

Study Drug - Durvalumab [30] 
1.3.1 
Description of Durvalumab (MEDI4736) 
Durvalumab is briefly described below. Investigators should refer to the current 
Investigator’s Brochure (IB) for details. 
1.3.2 
Product Derivation 
Durvalumab is being developed as a potential anticancer therapy for the treatment 
of multiple tumor types. Durvalumab is a human immunoglobulin (Ig) G1 kappa 
(IgG1κ) monoclonal antibody (MAb) that blocks the interaction of PD-L1 (but not 
programmed cell death ligand-2) with PD-1 on T-lymphocyte (T-cell) and, cluster of 
differentiation on CD80 (B7-1) on immune cells and is engineered to reduce 
antibody-dependent cell-mediated cytotoxicity (ADCC).
 
 
 
 
 
 
1.3.3 
Non Clinical Safety Profile 
The non-clinical experience is fully described in the current version of the 
durvalumab IB. 
Durvalumab binds with high affinity and specificity to human PD-L1 and blocks its 
interaction with PD-1 and CD80 (B7-1).

1.3.4 
Summary of Clinical Experience 
The clinical experience is fully described in the current version of the durvalumab 
IB. 
As of 12 July 2017, an estimated 4067 patients have been exposed to 1 or more 
doses of durvalumab in Phase I-III AstraZeneca or MedImmune sponsored studies, 
either as monotherapy or in combination and 5911 where the treatment arm is 
blinded. Additionally, more than 4000 patients have been exposed to 1 or more 
doses of durvalumab in externally-sponsored/investigator-initiated clinical trials. No 
AstraZeneca or MedImmune study has been terminated prematurely due to toxicity.

1.3.7 
Dose Rationale 
1.3.7.1 
Fixed Dosing 
A two compartment population PK model was developed for 
durvalumab using monotherapy data from Study CD-ON-MEDI4736-
1108 and the ATLANTIC Study across dose levels and tumor types 
 
 
. 
Population PK analysis indicated only minor impact of body weight on 
PK of durvalumab (coefficient of ≤ 0.5). The impact of body weight-
based (10 mg/kg Q2W or 20 mg/kg Q4W) and fixed dosing (750 mg 
Q2W or 1500 mg Q4W) of durvalumab was evaluated by comparing 
predicted steady state PK exposure (AUCss,0-28, Cmax,ss, and Cmin,ss ) using 
the population PK model. A fixed dose of 750 mg Q2W was selected to 
approximate 10 mg/kg Q2W and a fixed dose of 1500 mg Q4W was 
selected to approximate 20 mg/kg Q4W (based on median body weight 
of ~75 kg). A total of 1000 patients were simulated using body weight 
distribution of 40–110 kg. Simulation results demonstrate that body 
weight-based (10 mg/kg Q2W) and fixed dosing regimens (750 mg 
Q2W) yield similar median steady state exposures and associated 
variability, supporting the potential switch of durvalumab from weight-
based to fixed dose. Similar considerations hold for the Q4W dosing 
regimens (20 mg/kg Q4W versus 1500 mg Q4W). Based on an average 
body weight of 75 kg, fixed doses of 1120 mg q3w (equivalent to 15 
mg/kg q3w) of durvalumab are chosen for this study. 
Similar findings have been reported by others [31-35]. Wang and 
colleagues investigated 12 monoclonal antibodies and found that fixed 
and body size-based dosing perform similarly, with fixed dosing being 
better for 7 of 12 antibodies [32]. In addition, they investigated 18 
therapeutic proteins and peptides. 
1.4 
Study Drugs – Pemetrexed and Cisplatin or Carboplatin 
1.4.1 
Pemetrexed 
Pemetrexed is a folate analog metabolic inhibitor indicated for the treatment of 
mesothelioma in combination with cisplatin. Pemetrexed is administered 
intravenously at a dose of 500 mg/m² on Day 1 of each 21-day cycle. Cisplatin 
should be administered 30 minutes after pemetrexed infusion ends at a dose of 75 
mg/m². The premedication regimen for pemetrexed includes folic acid and vitamin 
B12 as well as dexamethasone or equivalent to reduce cutaneous reactions. 
Subjects receiving pemetrexed should be monitored prior to each dose using 
complete blood count (CBC) and renal function tests. If marrow suppression is 
noted, dose modifications are noted in Section 6.3.2, Table 6-3. For renal toxicity, 
pemetrexed should be held when the creatinine clearance (CrCl) <45 mL/minute. 
Caution should be used among subjects who are receiving nonsteroidal anti-
inflammatory drugs (NSAIDs) and who have mild to moderate renal insufficiency 
(CrCl between 45 and 79 mL/minute). Caution should also be used when 
nephrotoxic drugs are administered with pemetrexed. For preparation and storage, 
please consult the prescribing information for Alimta® [36].

1.4.2 
Cisplatin 
Cisplatin is a platinum-based drug that is used in mesothelioma. Cisplatin is 
administered intravenously at a dose of 75 mg/m² starting 30 minutes after 
pemetrexed infusion ends. Subjects who are receiving cisplatin must be monitored 
for nephrotoxicity, ototoxicity and neuropathy in addition to myelosuppression. 
Caution must be observed in the case of nausea, vomiting and dehydration. Dose 
modifications according to toxicities are noted in Section 6.3.2, Table 6-3. For 
preparation and storage, please consult the prescribing information for Cisplatin 
[37]. 
1.4.3 
Carboplatin 
Carboplatin is a platinum-based drug that is used in the treatment of mesothelioma 
in the setting where cisplatin is contraindicated. Carboplatin is administered 
intravenously at a dose of AUC 5 mg/mL*min (per Calvert formula) starting 15 to 30 
minutes after pemetrexed infusion ends. Subjects who are receiving carboplatin 
must be monitored for myelosuppression and anaphylaxis. Dose modifications 
according to toxicities are noted in Section 6.3.2, Table 6-3. For preparation and 
storage, please consult the prescribing information for Paraplatin [38].

Summary of Rationale for Proposed Study 
1.5.1 
Rationale for the Study Design and Treatment Plan 
1.5.1.1 
Current Standard of Care in Mesothelioma and Role for Maintenance 
Therapy 
Subjects enrolled on this study will have unresectable mesothelioma 
for which they have not received prior systemic therapy. The standard 
first-line therapy for mesothelioma consists of 4-6 cycles of combination 
chemotherapy with pemetrexed/cisplatin, this has been shown to 
extend survival when compared with cisplatin alone and is associated 
with a median OS of 12.1 months [39]. The benefit of second-line 
chemotherapy has not been clearly established [40]. 
No more than 4 to 6 cycles of first-line platinum-based combination 
chemotherapy are generally recommended for patients with advanced 
disease. Therefore, after 4 to 6 cycles of treatment, non-progressing 
patients enter a “watch-and-wait” period with periodic review until 
progression. Trials are ongoing evaluating the role of maintenance 
single agent pemetrexed after initial platinum doublet chemotherapy 
[41]. Further investigation would be advantageous to provide these 
patients with a regimen that could augment and then maintain the 
disease control achieved by first-line therapy. Similar approaches in 
NSCLC have led to the approval of both erlotinib and pemetrexed as 
maintenance treatment in patients who are not progressing following 
first-line platinum-based treatment, on the basis of an observed benefit 
in both median progression-free survival (PFS) and median OS. 
Currently there are no approved therapies following first-line treatment 
for malignant pleural mesothelioma, and there are limited data in the 
maintenance setting. 
1.5.1.2 
Rationale for Combination of Chemotherapy and Durvalumab 
The interaction of a tumor with the immune system is complex. Tumors 
and the tumor microenvironment are known to express a variety of 
factors that impede a robust immune response from eliminating the 
tumor.

Cancer 
therapeutics 
such 
as 
chemotherapy 
may 
modulate 
tumor/immune-system interactions in favor of the immune system. 
Chemotherapy can result in tumor cell death with a resultant increase 
in tumor antigen delivery to antigen-presenting cells. Tumor cell death 
may also lead to a reduction in soluble and membrane-bound factors 
inhibiting tumor-infiltrating T-cells. Chemotherapy may also disrupt 
immune system regulatory networks by decreasing numbers of T-
regulatory cells. 
In previously untreated mesothelioma, chemotherapy has the potential 
to prime the immune system through tumor destruction and consequent 
antigen expression. The addition of durvalumab to chemotherapy is 
expected to be synergistic in this regard. Several studies are exploring 
the combination of chemotherapy with anti-PD-L1 therapies with 
promising early response data. 
1.6 
Synopsis of Study Design 
1.6.1 
Initial Enrollment and Evaluation for Safety (Safety Run-In Period)  
As durvalumab has not been previously combined with pemetrexed platinum 
doublet chemotherapy the study will commence with an initial enrollment of 6 
patients who will receive the combination of pemetrexed (500 mg/m2) and cisplatin 
(75 mg/m2) with durvalumab (1120 mg) for up to 6 cycles. Pemetrexed/carboplatin 
is associated with fewer toxicities than pemetrexed/cisplatin therefore both in the 
initial 6 patient cohort and in the later expansion, substitution of carboplatin (AUC 
5) for cisplatin will be permitted specifically as outlined in the eligibility. After up to 
6 cycles of concurrent chemotherapy with durvalumab, patients who have a PR or 
SD will continue on durvalumab until disease progression (maximum duration of 
durvalumab treatment is 12 months starting from Cycle 1 of concurrent treatment 
(inclusive of any treatment delays or missed treatments). In this initial safety run-in 
period subjects will be monitored for safety. The combination will be declared 
intolerable if ≥ 2 of the initial 6 patients experience a dose-limiting toxicity (DLT) as 
defined in the protocol and occurring during the first 2 cycles of concurrent therapy. 
The detailed statistical analysis plan is described in the statistical section of this 
protocol. 
1.6.2 
Expansion 
After the initial 6 patients from the above safety run-in period have been monitored 
for safety the study will proceed with enrollment for a total of 55 patients (including 
the initial 6 patient safety run-in) of whom it is expected 50 patients will receive 
treatment (ineligibility rate of 10%). This is an open label, single arm phase II study 
evaluating the benefit of durvalumab in combination with pemetrexed/cisplatin for 
the treatment of first-line unresectable pleural mesothelioma. Durvalumab (1120 mg 
q 3 weeks) will be administered concurrently with up to 6 cycles of first line 
pemetrexed (500 mg/m2) and cisplatin (75 mg/m2) followed by maintenance 
durvalumab until disease progression (maximum duration of durvalumab treatment 
is 12 months starting from Cycle 1 of concurrent treatment (inclusive of any 
treatment delays or missed treatments). Carboplatin (AUC 5) may be substituted 
for cisplatin for patients with a documented contraindication (e.g., ototoxicity, renal 
function) to use of cisplatin and these patients must otherwise fulfill the eligibility 
criteria (Section 3). In addition, for patients who receive cisplatin, carboplatin may 
be substituted after Cycle 1 for cisplatin related toxicity (e.g., grade 3 ototoxicity, 
grade 3 nausea) at the investigator’s discretion.

1.6.3 
Evaluation of Subjects 
Progression will be assessed locally using modified RECIST Version 1.1. Subjects 
will continue to receive treatment until disease progression or other discontinuation 
criteria are met (maximum duration of durvalumab treatment is 12 months starting 
from Cycle 1 of concurrent treatment (inclusive of any treatment delays or missed 
treatments). Removal of subjects for clinical progression will be at the discretion of 
the Investigator. Response assessments will be performed every 6 weeks (2 doses 
of treatment) for the first 18 weeks. After 18 weeks of treatment, response 
assessments will be performed every 9 weeks (3 doses of treatment). The same 
method of assessment should be used throughout the study. 
Following documentation of non-fatal confirmed disease progression, all subjects 
will be followed for survival (either routine clinic visit or telephone contact) every 3 
months until death or the closure of the study.

3) Progression-free survival (PFS) will be measured from the time of study registration until 
radiologic progression, clinical progression or death. 
4) Time to progression on durvalumab will be measured from the time concurrent 
treatment with chemotherapy/durvalumab begins until radiologic or clinical progression 
is noted. 
5) Best Objective Response Rate (ORR) evaluation will continue up to 1 year on therapy 
and response will be coded based on modified RECIST Version 1.1 criteria for 
mesothelioma. 
2.3 
Exploratory Objectives 
2.3.1 
Laboratory Correlates of Response (depending on sample availability) 
1) Assessment of tumor baseline PD-L1 expression may be performed. 
2) Assessment of the genomic and neoantigen landscape of baseline tumors may 
be performed. 
3) Assessment of dynamics of circulating cell free tumor DNA (ctDNA) may be 
performed.

Study Design 
5.1 
Overview 
This is a single arm, unblinded, open-label phase 2 study of durvalumab administered 
concurrently with pemetrexed/cisplatin chemotherapy as first-line treatment for 
unresectable pleural mesothelioma. The first six patients enrolled will be monitored for 
safety of the combination. A maximum of 55 patients (50 patients to be treated with expected 
ineligibility rate of 10%) will be enrolled and will receive up to 6 three week cycles of 
concurrent durvalumab with chemotherapy. Patients with responding or stable disease after 
six cycles of concurrent treatment will continue on durvalumab as a single agent 
administered once every 3 weeks. Maximum duration of durvalumab treatment is 12 months 
(inclusive of any treatment delays or missed treatments) starting from Cycle 1 of concurrent 
treatment. 
Carboplatin may be substituted for cisplatin in patients with a documented contraindication 
(e.g., ototoxicity, renal function) to the use of cisplatin. These patients must otherwise fulfill 
the eligibility criteria (Section 3). In addition, for patients who receive cisplatin, carboplatin 
may also be substituted after Cycle 1 for cisplatin related toxicity (e.g., grade 3 ototoxicity, 
grade 3 nausea) at the investigator’s discretion. Once carboplatin is substituted for cisplatin, 
patients cannot change back to cisplatin. 
The study will be conducted at up to 26 US-based study centers. 
All subjects will be evaluated regularly and their clinical status classified according to 
RECIST guidelines Version 1.1 [42] with modifications for pleural mesothelioma. All subjects 
will be followed for survival until the end of study (Section 7.2). AEs and SAEs will be 
followed as per Section 8. The objectives are described in Section 2. 
5.2 
Initial Enrollment of Six Patients with Safety Monitoring 
As durvalumab has not been previously combined with pemetrexed platinum chemotherapy 
the study will commence with an initial enrollment of 6 patients who will receive pemetrexed 
and cisplatin (or carboplatin described in Section 3 and Section 5.1) combined with 
durvalumab for up to 6 cycles. After 6 cycles patients who have a PR or SD will continue on 
durvalumab until disease progression. In this initial run-in period subjects will be monitored 
for safety. The combination will be declared intolerable if ≥ 2 of the 6 patients experience a 
DLT defined in Section 6.2 occurring during the first 2 cycles of concurrent therapy phase. 
The initial 6 patients completed 2 cycles of concurrent therapy with no DLTs. 
The detailed statistical analysis plan is described in Section 12 of this protocol. 
5.3 
Expansion 
The initial six patients were monitored for safety, without suspension to accrual and, the 
study will proceed with enrollment for a total of 55 patients 
An Interim Safety Analysis on the first 15 patients who completed two cycles of therapy was 
also completed without suspension to accrual (Section 12.2.5 for details) and no safety 
concerns noted. It is expected that 50 of the 55 patients enrolled will receive treatment 
(ineligibility rate of 10%). Carboplatin may be substituted for cisplatin for patients with a 
documented contraindication (e.g., ototoxicity, renal function) to use of cisplatin and these 
patients must otherwise fulfill the eligibility criteria as noted in Section 3 and above in Section 
5.1. 
5.4 
Evaluation of Subjects 
Progression will be assessed using RECIST Version 1.1 modified for mesothelioma. 
Subjects will continue to receive treatment until disease progression or other discontinuation 
criteria are met. Removal of subject for clinical progression will be at the discretion of the 
Investigator. If a patient is deriving clinical benefit they may continue durvalumab (either

concurrent or single agent) until a repeat scan at least 4 weeks later (Section 9.1.5). 
Response assessments will be performed every 6 weeks for the first 18 weeks. After 18 
weeks of treatment, response assessments will be performed every 9 weeks. The same 
method of assessment should be used throughout the study. 
Following documentation of non-fatal confirmed disease progression, all subjects will be 
followed for survival (either routine clinic visit or telephone contact) every 3 months until 
death or the close of the study.

Durvalumab will be administered before pemetrexed and cisplatin chemotherapy. 
Durvalumab 1120 mg will be administered by an infusion pump as an IV infusion 
over approximately 60 minutes (±5 minutes), using a 0.2, or 0.22-μm in-line filter. 
Less than 55 minutes will be considered a deviation. 
Standard infusion time is 1 hour. However, if there are interruptions during infusion, 
the total allowed time should not exceed 8 hours at room temperature. Please refer 
to Section 11.1 and guidelines in Section 11.1.7 and Table 11-1. 
6.1.2 
Pemetrexed/Cisplatin Administration 
The recommended dose of pemetrexed is 500 mg/m2 administered as an 
intravenous infusion over 10 minutes (or per investigator discretion and local 
standard-of-care) on Day 1 of each 21-day cycle. 
During concurrent treatment days, pemetrexed infusion will begin approximately 30 
minutes after the infusion of durvalumab has finished (or per investigator discretion 
and local standard-of-care). 
The recommended dose of cisplatin is 75 mg/m2 infused over 2 hours beginning 
approximately 30 minutes after the end of pemetrexed administration (or per 
investigator discretion and local standard-of-care). Patients should receive 
appropriate hydration prior to and/or after receiving cisplatin. Hydration may 
commence prior to or concurrently with durvalumab. 
If carboplatin is substituted for cisplatin per Section 3.9 and Section 5.1, the 
recommended dose of carboplatin is AUC 5 infused over 30 minutes beginning 
approximately 15-30 minutes after the end of the pemetrexed administration (or per 
investigator discretion and local standard-of-care). 
CALVERT FORMULA FOR CARBOPLATIN DOSING 
Total Dose (mg) = (target AUC) x (CrCL by Cockcroft-Gault [Appendix II] + 25) 
Please refer to Section 11.2 for additional information. 
6.1.2.1 
Pemetrexed Premedication 
Oral corticosteroid should be given according to local standards at a 
dose equivalent to dexamethasone 4 mg BID on the day prior to, the 
day of, and the day after the administration of pemetrexed. Oral folic 
acid 350 to 1000 µg daily should be given starting 1 week prior to the 
first dose of pemetrexed, with at least 5 doses of folic acid administered 
in the 7 days prior to the first dose. Oral folic acid should be continued 
daily throughout the treatment with pemetrexed and for 21 days after 
the last dose of pemetrexed has been administered. Intramuscular (IM)

injection of Vitamin B12 1000 µg should be given approximately one 
week prior to the first dose of pemetrexed and repeated on the day that 
the third and sixth pemetrexed treatment is administered. Oral folic acid 
and Vitamin B12 injection may also be given per local standard of care. 
6.1.2.2 
Cisplatin Premedication 
Cisplatin will be administered to patients at least 30 minutes following 
the end of the pemetrexed infusion. Pretreatment hydration for cisplatin 
can follow local standard of care or use of 1 to 2 liters of fluid (per local 
standards) infused IV for 2-4 hours prior to cisplatin infusion is 
recommended. Adequate hydration and urinary output must be 
maintained for at least 24 hours following cisplatin administration. 
Administration and monitoring should be performed according to local 
standards. Use of mannitol following the cisplatin infusion should also 
follow local standard-of-care. 
6.1.2.3 
Carboplatin Premedication 
If carboplatin has been substituted for cisplatin per Section 3.9 or 
Section 5.1, premedication should follow local standard-of-care. 
6.1.2.4 
Antiemetics for use with Pemetrexed/Cisplatin (Carboplatin) 
Antiemetic premedication will be administered according to local 
standards. Recommended antiemetic treatments are dexamethasone 
(dosing according to local standards; an equivalent dose of another 
corticosteroid may be substituted) and a 5-HT3 receptor antagonist 
(type per investigator discretion and local standard-of-care). Additional 
use of antiemetic premedications may be employed at the discretion of 
the Investigator. 
6.1.3 
Pemetrexed/Cisplatin (or Carboplatin) Re-Treatment 
Prior to each treatment with pemetrexed/cisplatin (carboplatin), the following 
conditions must be met. 
• 
ANC must be ≥ 1500/mm3 and platelets ≥ 100,000/mm3 prior to the start of each 
cycle. Growth factor support is permitted, and should be administered per 
American Society of Clinical Oncology (ASCO) guideline. 
• 
Pemetrexed: CrCL ≥ 45. 
• 
Cisplatin: Serum creatinine ≤ 1.5 or CrCL ≥ 50. 
o 
Carboplatin may be substituted for cisplatin in patients with ≤ Grade 2 renal 
function at the investigator’s discretion. Once carboplatin is substituted for 
cisplatin, patients cannot change back to cisplatin. 
• 
Carboplatin: CrCL ≥ 45. 
• 
All other drug-related non-hematologic toxicities must have improved to 
baseline or ≤ Grade 2. Exceptions to this criterion include alopecia and other 
toxicities of non-vital organs. 
Treatment may be delayed for up to 3 weeks to allow sufficient time for recovery 
from treatment-related toxicities. If a delay greater than 3 weeks is required, the 
Investigator should confer with PrECOG to determine the appropriateness of 
continued treatment. In the event of a treatment delay, subsequent cycles should 
occur relative to the delayed cycle (maintaining a 3-week cycle interval). In other 
words, subsequent cycles should not be shortened to “make-up” for any delays.

Dose Limiting Toxicity - Definition 
DLT, as defined below, will be evaluated for the first 2 cycles (2 doses) of concurrent therapy 
with durvalumab, pemetrexed and cisplatin. Toxicity that is clearly and directly related to the 
primary disease or to another etiology is excluded from this definition. The following will be 
DLTs: 
• 
Any Grade 4 immune-mediated adverse event (imAE) 
• 
Any ≥ Grade 3 colitis 
• 
Any Grade 3 or 4 non-infectious pneumonitis irrespective of duration 
• 
Any Grade 2 pneumonitis that does not resolve to ≤ Grade 1 within 3 days of the 
initiation of maximal supportive care 
• 
Any Grade 3 imAE, excluding colitis or pneumonitis, that does not downgrade to Grade 
2 within 3 days after onset of the event despite optimal medical management including 
systemic corticosteroids or does not downgrade to ≤ Grade 1 or baseline within 14 days 
• 
Liver transaminase elevation >8x ULN or total bilirubin >5x ULN 
The definition excludes the following conditions: 
• 
Grade 3 fatigue lasting ≤ 7 days 
• 
Grade 3 endocrine disorder (thyroid, pituitary, and/or adrenal insufficiency) that is 
managed with or without systemic corticosteroid therapy and/or hormone replacement 
therapy and the subject is asymptomatic 
• 
Grade 3 inflammatory reaction attributed to a local antitumor response (e.g., 
inflammatory reaction at sites of metastatic disease, lymph nodes, etc.) 
• 
Concurrent vitiligo or alopecia of any AE grade 
• 
Grade 3 infusion-related reaction (first occurrence and in the absence of steroid 
prophylaxis) that resolves within 6 hours with appropriate clinical management 
• 
Grade 3 or 4 neutropenia that is not associated with fever or systemic infection that 
improves by at least 1 grade within 3 days. Grade 3 or Grade 4 febrile neutropenia will 
be a DLT regardless of duration or reversibility. 
• 
Grade 3 or 4 lymphopenia 
• 
Grade 3 thrombocytopenia that is not associated with clinically significant bleeding that 
requires medical intervention, and improves by at least 1 grade within 3 days 
• 
Isolated Grade 3 electrolyte abnormalities not associated with clinical signs or 
symptoms and reversed with appropriate maximal medical intervention within 3 days 
Immune-mediated AEs are defined as AEs of an immune nature (i.e., inflammatory) in the 
absence of a clear alternative etiology. In the absence of a clinically significant abnormality, 
repeat laboratory testing will be conducted to confirm significant laboratory findings prior to 
designation as a DLT. 
6.2.1 
DLT Assessment – Initial Enrollment of Six Patients 
For the purposes of safety decision making during the initial enrollment of six 
patients, DLTs will be evaluated for the first 2 cycles (2 doses) of concurrent therapy 
with durvalumab, pemetrexed and cisplatin. DLTs occurring beyond this window will 
be taken into account when determining whether to proceed to enroll the full 
planned cohort of 55. DLTs will be monitored for the first 2 cycles (42 days) of 
concurrent therapy. Depending on the rate of accrual and review of the data 
pertaining to DLT evaluation, accrual may be halted to ensure it is safe to continue 
patient enrollment.

6.2.2 
Phase II Treatment Administration 
During the total enrollment of 55 patients (50 expected to commence therapy), 
toxicity will continue to be closely monitored. Because this is the first time that 
durvalumab is being combined with pemetrexed/cisplatin in this setting, close 
monitoring of toxicity is an important endpoint of the trial. We will also collect data 
and conduct an interim safety analysis among the first 15 patients who have 
completed the first 2 cycles (6 weeks) of concurrent therapy without suspension to 
accrual. The safety analysis will be done based on the electronic case report form 
(eCRF) database. This preliminary toxicity analysis will occur in addition to the twice 
yearly monitoring for toxicity for the purposes of interim reporting. 
Interim analysis on first 15 patients who completed the first 2 cycles of concurrent 
therapy showed no safety concerns. 
6.3 
Dose Delays & Modifications 
All toxicities should be graded according to the National Cancer Institute (NCI) 
Common Terminology Criteria for Adverse Events Version 4.0 (CTCAE V4.03). A copy 
of 
the 
CTCAE 
V4.03 
can 
be 
downloaded 
from 
the 
CTEP 
website 
(http://www.ctep.cancer.gov). 
A 3 day window is allowed for scheduled therapy, tests and/or results except as noted below 
for CBC with differential and platelet count. Delays due to holidays, weekends, bad weather 
or other unforeseen circumstances will be permitted. 
6.3.1 
Durvalumab 
For AEs that are considered at least partly due to administration of durvalumab, the 
following dose adjustment guidance may be applied: 
• 
Treat each of the toxicities with maximum supportive care (including holding the 
agent suspected of causing the toxicity where required). 
• 
If the symptoms promptly resolve with supportive care, consideration should be 
given to continuing the same dose of durvalumab along with appropriate 
continuing supportive care. If medically appropriate, dose modifications are 
permitted for durvalumab (Table 6-1 and 6-2). 
• 
All dose modifications should be documented with clear reasoning and 
documentation of the approach taken. 
In addition, there are certain circumstances in which durvalumab should be 
permanently discontinued. 
Following the first dose of durvalumab, subsequent administration of durvalumab 
can be modified based on toxicities observed (Table 6-1 and 6-2). Dose reductions 
are not permitted for durvalumab. 
Based on the mechanism of action of durvalumab leading to T-cell activation and 
proliferation, there is the possibility of observing immune mediated Adverse Events 
(imAEs) during the conduct of this study. Potential imAEs include immune-mediated 
enterocolitis, dermatitis, hepatitis, and endocrinopathies. Subjects should be 
monitored for signs and symptoms of imAEs. In the absence of an alternate etiology 
(e.g., infection or PD) signs or symptoms of enterocolitis, dermatitis, hepatitis, and 
endocrinopathy should be considered to be immune-related. 
NOTE: Patients with previous history of bleeding and/or are taking anticoagulant 
medication may have a higher risk of subsequent bleeding. Monitor patients 
closely for possible bleeding.

Dose modification recommendations and toxicity management guidelines for 
immune-mediated reactions, for infusion-related reactions, and for non-immune-
mediated reactions are detailed in Tables 6-1 and 6-2, respectively. 
Patients must have at least 2 cycles of pemetrexed/cisplatin (or carboplatin) with 
durvalumab in order to be eligible to proceed to maintenance durvalumab. 
In addition, management guidelines for adverse events of special interest (AESIs) 
are detailed in Section 8.2. All toxicities will be graded according to NCI CTCAE 
V4.03.

Dose Modifications 
Toxicity Management 
Immune-Mediated 
Adverse Events 
(Overall Management 
For toxicities not noted 
below) 
Drug administration modifications of study drug/study regimen will be made 
to manage potential immune-mediated AEs based on severity of treatment-
emergent toxicities graded per NCI CTCAE V4.03. 
In addition to the criteria for permanent discontinuation of study drug/regimen 
based on CTC grade/severity (table below), permanently discontinue study 
drug/study regimen for  the following conditions: 
• 
Inability to reduce corticosteroid to a dose of ≤ 10 mg of prednisone per 
day (or equivalent) within 12 weeks after last dose of study drug/regimen. 
• 
Recurrence of a previously experienced Grade 3 treatment-related AE 
following resumption of dosing. 
It is recommended that management of immune-mediated 
adverse events (imAEs) follow the guidelines presented in this 
table: 
- 
It is possible that events with an inflammatory or immune 
mediated mechanism could occur in nearly all organs, 
some of them not noted specifically in these guidelines. 
- 
Whether 
specific 
immune-mediated 
events 
(and/or 
laboratory indication of such events) are noted in these 
guidelines or not, patients should be thoroughly evaluated 
to rule out any alternative etiology (e.g., disease 
progression, concomitant medications, infections, etc.) to a 
possible immune-mediated event. In the absence of a clear 
alternative etiology, all such events should be managed as 
if they were immune related. 
General Recommendations: 
- 
Symptomatic and topical therapy should be considered for 
low-grade (Grade 1 or 2, unless otherwise specified) 
events. 
- 
For persistent (>3 to 5 days) low-grade (Grade 2) or severe 
(Grade ≥ 3) events promptly start prednisone 1-2 
mg/kg/day PO or IV equivalent. 
- 
Some events with high likelihood for morbidity and/or 
mortality – e.g., myocarditis, or other similar events even if 
they are not currently noted in the guidelines – should 
progress 
rapidly 
to 
high 
dose 
IV 
corticosteroids 
(methylprednisolone at 2 to 4 mg/kg/day) even if the event 
is Grade 2, and if clinical suspicion is high and/or there has 
been clinical confirmation. Consider, as necessary, 
discussing with the study physician, and promptly pursue 
specialist consultation. 
- 
If symptoms recur or worsen during corticosteroid tapering 
(28 days of taper), increase the corticosteroid dose 
(prednisone dose [e.g. up to 2-4 mg/kg/day PO or IV 
equivalent]) 
until 
stabilization 
or 
improvement 
of 
symptoms, then resume corticosteroid tapering at a slower 
rate (>28 days of taper). 
Grade 1 
No dose modification 
Grade 2 
Hold study drug/study regimen dose until Grade 2 resolution to 
≤ Grade 1. 
• 
If toxicity worsens then treat as Grade 3 or Grade 4. 
- Study drug/study treatment can be resumed once event 
stabilizes to Grade ≤ 1 after completion of steroid taper. 
- Patients with endocrinopathies who may require prolonged or 
continued steroid replacement can be retreated with study 
drug/study regimen on the following conditions: 
1) 
Event stabilizes and is controlled 
2) 
Patient is clinically stable as per Investigator or treating 
physician’s clinical judgement, and 
3) 
Doses of prednisone are ≤ 10 mg/day or equivalent. 
Grade 3 
Depending on the individual toxicity, may permanently discontinue 
study drug/ study regimen. Please refer to guidelines below. 

PrECOG Protocol Number: PrE0505

Grade 4 
Permanently discontinue study drug/ study regimen. 
NOTE: For Grade 3 and above asymptomatic amylase or lipase 
levels hold study drug/regimen and if complete work up 
shows no evidence of pancreatitis, may continue or 
resume study drug/regimen. 
NOTE: Study drug/study regimen should be permanently 
discontinued in Grade 3 events with high likelihood for 
morbidity and/or mortality – e.g., myocarditis, or other 
similar events even if they are not currently noted in the 
guidelines. Similarly, consider whether study drug/study 
regimen should be permanently discontinued in Grade 2 
events with high likelihood for morbidity and/or mortality 
– e.g., myocarditis, or other similar events even if they 
are not currently noted in the guidelines – when they do 
not rapidly improve to Grade <1 upon treatment with 
systemic steroids and following full taper. 
NOTE: There are some exceptions to permanent discontinuation 
of study drug for Grade 4 events (i.e., hypo or hyper-
thyroidism, Type 1 diabetes mellitus) 
- 
More potent immunosuppressives such as TNF inhibitors 
(e.g., infliximab) - (also refer to individual sections of the 
imAE for specific type of immunosuppressive) should be 
considered for events not responding to systemic steroids. 
Progression to use of more potent immunosuppressives 
should proceed more rapidly in events with high likelihood 
for morbidity and/or mortality – e.g., myocarditis, or other 
similar events even if they are not currently noted in the 
guidelines – when these events are not responding to 
systemic steroids. 
- 
With long-term steroid and other immunosuppressive use, 
consider need for Pneumocystis jirovecii pneumonia (PJP, 
formerly known as Pneumocystis carinii pneumonia) 
prophylaxis, gastrointestinal protection, and glucose 
monitoring. 
- 
Discontinuation of study drug is not mandated for Grade 
3/Grade 4 inflammatory reactions attributed to local tumor 
response (e.g. inflammatory reaction at sites of metastatic 
disease, lymph nodes etc.). Continuation of study drug in 
this situation should be based upon a benefit/risk analysis 
for that patient.

(Symptomatic, medical 
intervention indicated, 
limiting instrumental 
ADL) 
Hold study drug/study regimen dose until 
Grade 2 resolution to ≤ Grade 1. 
• If toxicity worsens then treat as Grade 
3 or Grade 4. 
• If toxicity improves to ≤ Grade 1, then 
the 
decision 
to 
reinitiate 
study 
drug/regimen will be based upon 
treating physician’s clinical judgment 
and after completion of steroid taper. 
For Grade 2 (Mild to Moderate New Symptoms) 
- 
Monitor symptoms daily and consider hospitalization. 
- 
Promptly start systemic steroids (e.g., prednisone 1-2 mg/kg/day 
PO or IV equivalent). 
- 
Reimaging as clinically indicated. 
- 
If no improvement within 3-5 days, additional workup should be 
considered and prompt treatment with IV methylprednisolone 2-

Immune-Mediated 
Peripheral Neuromotor 
Syndromes, such as 
Guillain-Barre and 
Myasthenia Gravis 
Any Grade 
General Guidance 
- 
The 
prompt 
diagnosis 
of 
immune-mediated 
peripheral 
neuromotor syndromes is important, since certain patients may 
unpredictably experience acute decompensations that can result 
in substantial morbidity or in the worst case, death. Special care 
should be taken for certain sentinel symptoms that may predict 
a more severe outcome, such as prominent dysphagia, rapidly 
progressive weakness, and signs of respiratory insufficiency or 
autonomic instability. 
- 
Patients should be evaluated to rule out any alternative etiology 
(e.g., disease progression, infections, metabolic syndromes and 
medications, etc.). It should be noted that the diagnosis of 
immune-mediated peripheral neuromotor syndromes can be 
particularly challenging in patients with underlying cancer, due to 
the multiple potential confounding effects of cancer (and its 
treatments) throughout the neuraxis. Given the importance of 
prompt and accurate diagnosis, it is essential to have a low 
threshold to obtain a neurological consult. 
- 
Neurophysiologic diagnostic testing (e.g., electromyogram and 
nerve conduction investigations, and “repetitive stimulation” if 
myasthenia is suspected) are routinely indicated upon suspicion 
of such conditions and may be best facilitated by means of a 
neurology consultation. 
- 
It is important to consider that the use of steroids as the primary 
treatment of Guillain-Barre is not typically considered effective. 
Patients requiring treatment should be started with IVIG and 
followed by plasmapheresis if not responsive to IVIG. 
Grade 1

MYASTHENIA GRAVIS 
o 
Steroids may be successfully used to treat Myasthenia 
Gravis. It is important to consider that steroid therapy 
(especially with high doses) may result in transient 
worsening 
of 
myasthenia 
and 
should 
typically 
be 
administered in a monitored setting under supervision of a 
consulting neurologist. 
o 
Patients unable to tolerate steroids may be candidates for 
treatment with plasmapheresis or IVIG. Such decisions are 
best made in consultation with a neurologist, taking into 
account the unique needs of each patient. 
o 
If Myasthenia Gravis-like neurotoxicity present, consider 
starting acetylcholine esterase (AChE) inhibitor therapy in 
addition to steroids. Such therapy, if successful, can also 
serve to reinforce the diagnosis. 
GUILLAIN-BARRE 
o 
Important to consider here that the use of steroids as the

Myocarditis 
Any grade 
General Guidance 
Discontinue drug permanently if biopsy-
proven immune-mediated myocarditis 
- 
The prompt diagnosis of immune-mediated myocarditis is 
important, particularly in patients with baseline cardiopulmonary 
disease and reduced cardiac function. 
- 
Consider, as necessary, discussing with the study physician. 
- 
Monitor patients for signs and symptoms of myocarditis (new 
onset or worsening chest pain, arrhythmia, shortness of breath, 
peripheral edema). As some symptoms can overlap with lung 
toxicities, simultaneously evaluate for and rule out pulmonary 
toxicity as well as other causes (e.g., pulmonary embolism, 
congestive heart failure, malignant pericardial effusion). A 
Cardiology consultation should be obtained early, with prompt 
assessment of whether and when to complete a cardiac biopsy, 
including any other diagnostic procedures. 
− 
Initial work-up should include clinical evaluation, BNP, cardiac 
enzymes, ECG, echocardiogram (ECHO), monitoring of 
oxygenation via pulse oximetry (resting and exertion), and 
additional laboratory work-up as indicated. Spiral CT or cardiac 
MRI can complement ECHO to assess wall motion abnormalities 
when needed. 
- 
Patients should be thoroughly evaluated to rule out any 
alternative 
etiology 
(e.g., 
disease 
progression, 
other 
medications, or infections).

etiologies. If study drug/study regimen is 
held, resume after complete resolution to 
Grade 0. 
For Grade 1 (no definitive findings): 
- 
Monitor and closely follow up in 2 to 4 days for clinical symptoms, 
BNP, cardiac enzymes, ECG, ECHO, pulse oximetry (resting and 
exertion), and laboratory work-up as clinically indicated. 
- 
Consider using steroids if clinical suspicion is high.

• 
If Grade 3-4, permanently discontinue 
study drug/study regimen. 
For Grade 2-4: 
− 
Monitor symptoms daily, hospitalize. 
− 
Promptly start IV methylprednisolone 2 to 4 mg/kg/day or 
equivalent after Cardiology consultation has determined whether 
and when to complete diagnostic procedures including a cardiac 
biopsy. 
− 
Supportive care (e.g., oxygen). 
− 
If 
no

days 
despite 
IV 
methylprednisolone at 2 to 4 mg/kg/day, promptly start 
immunosuppressive 
therapy 
such 
as 
TNF 
inhibitors 
(e.g., infliximab at 5 mg/kg every 2 weeks). Caution: It is 
important to rule out sepsis and refer to infliximab label for 
general guidance before using infliximab. 
− 
Once the patient is improving, gradually taper steroids over ≥28 
days and consider prophylactic antibiotics, antifungals, or anti-
PJP treatment (refer to current NCCN guidelines for treatment of 
cancer-related infections [Category 2B recommendation]). 
Myositis/Polymyositis 
(“Poly/myositis”) 
Any Grade 
General Guidance 
− 
Monitor patients for signs and symptoms of poly/myositis. 
Typically, muscle weakness/pain occurs in proximal muscles 
including upper arms, thighs, shoulders, hips, neck and back, but 
rarely affects the extremities including hands and fingers; also 
difficulty breathing and/or trouble swallowing can occur and 
progress rapidly. Increased general feelings of tiredness and 
fatigue may occur, and there can be new-onset falling, difficulty 
getting up from a fall, and trouble climbing stairs, standing up 
from a seated position, and/or reaching up.

Pemetrexed and Cisplatin (or Carboplatin) 
Chemotherapy dose modifications will be performed according to Table 6-3 below. 
Subjects will be monitored for adverse events while receiving doublet 
chemotherapy regimens. Dose interruptions or reductions may be required. 
Chemotherapy dose modifications must be determined according to standard 
practice and clinical determination as to whether dose modification is necessary. 
Chemotherapy dose modifications are permanent; once the dose of any 
chemotherapy agent had been reduced it will remain reduced or be further reduced 
in subsequent cycles. The dose reductions are not linked and may be adjusted 
independently as summarized below.

nonsteroidal anti-inflammatory drugs (NSAIDs) and who have mild to 
moderate renal insufficiency (CrCl between 45 and 79 mL/minute). 
Caution should also be used when nephrotoxic drugs are administered 
with pemetrexed. 
Any subject with two prior dose reductions to one agent who experiences a toxicity 
that would cause a third dose reduction must be discontinued from that agent. A 
subject who is discontinued from the chemotherapy treatment will remain on the 
study and receive durvalumab as maintenance monotherapy as per the 
maintenance study calendar. 
Patients must have at least 2 cycles of pemetrexed/cisplatin (or carboplatin) with 
durvalumab in order to be eligible to proceed to maintenance durvalumab provided: 
1. Pemetrexed/cisplatin (or carboplatin) is discontinued before 6 cycles for toxicity 
reasons and the toxicity must have been attributable to the chemotherapy and 
not to the durvalumab. 
AND 
2. Patients have either stable or responsive disease on imaging OR are continuing 
beyond progression per Section 9.1.5 (e.g., renal failure attributed to cisplatin 
and pemetrexed but not to durvalumab and scans show a response or are 
stable, patient could proceed to durvalumab maintenance).

Concurrent Therapies 
6.4.1 
Permitted 
Investigators may prescribe concomitant medications or treatments (e.g., 
acetaminophen, diphenhydramine) deemed necessary to provide adequate 
prophylactic or supportive care except for those medications identified as 
“excluded” as listed in Section 6.4.2. 
6.4.2 
Not Permitted 
The following medications are not permitted during the study. 
1. Any other investigational anticancer therapy. 
2. Any 
other 
concurrent 
chemotherapy, 
radiotherapy 
(except 
palliative 
radiotherapy), immunotherapy, biologic or hormonal therapy for cancer 
treatment. Concurrent use of hormones for non-cancer-related conditions (e.g., 
insulin for diabetes and hormone replacement therapy) is acceptable. 
NOTE: 
Local treatment of isolated lesions for palliative intent is acceptable 
(e.g., by local surgery or radiotherapy). Palliative radiation may be 
given as clinically indicated and must start at least one week after 
dose of pemetrexed/cisplatin and/or durvalumab or must be 
completed 
at 
least 
one 
week 
before 
next 
dose 
of 
pemetrexed/cisplatin and/or durvalumab 
3. Immunosuppressive medications including, but not limited to systemic 
corticosteroids at doses not exceeding 10 mg/day of prednisone or equivalent, 
methotrexate, azathioprine, and TNF-α blockers. Use of immunosuppressive 
medications for the management of investigational product-related AEs or in 
subjects with contrast allergies is acceptable. In addition, use of inhaled and 
intranasal corticosteroids is permitted. A temporary period of steroids will be 
allowed for different indications, at the discretion of the principal investigator 
(e.g., chronic obstructive pulmonary disease, radiation, nausea, etc.). 
4. Live attenuated vaccines within 30 days of durvalumab dosing (i.e., 30 days 
prior to the first dose, during treatment with durvalumab and for 30 days post 
discontinuation of durvalumab. Inactivated vaccines, such as the injectable 
influenza vaccine and the pneumococcal sub-unit or conjugate vaccine, are 
permitted. Herpes Zoster vaccine is a live attenuated vaccine and is not 
permitted.

Study Duration and Discontinuation of Therapy 
7.1 
Study Duration 
Patients will receive protocol therapy unless: 
1. Disease progression per modified RECIST Version.1.1 guidelines (notwithstanding the 
specific criteria for treatment beyond progression outlined in Section 9.1.5) or clinical 
progression. 
2. Toxicities considered unacceptable by either the patient or the investigator, despite 
optimal supportive care and dose modifications. 
3. Development of an inter-current illness that prevents further administration of study 
treatment. 
4. Extraordinary Medical Circumstances: If at any time the constraints of this protocol are 
detrimental to the patient's health, protocol treatment should be discontinued. 
5. Patient withdraws consent or is unable to comply with study procedures. 
7.2 
Duration of Follow-Up 
Patients will be followed for adverse events for 90 days after their last dose of durvalumab 
or until initiation of alternative anticancer therapy. 
If a patient is removed from treatment for reason(s) other than progression, follow with 
regular tumor assessments per standard of care until progression or start of new treatment. 
Following documentation of non-fatal confirmed disease progression, all subjects will be 
followed for survival (either routine clinic visit or telephone contact) every 3 months until 
death or the close of the study. 
For patients who are registered but do not receive any protocol therapy, baseline and follow-
up information per Section 10 will be collected. 
7.3 
Criteria for Removal from Study Treatment  
A genuine effort will be made to determine the reason(s) why a patient fails to return for the 
necessary visits or is discontinued from the trial, should this occur. It will be documented 
whether or not each patient completed the clinical study. If for any patient study treatment 
or observations were discontinued, the reason will be recorded on the appropriate eCRF. 
Reasons that a patient may discontinue treatment in a clinical study are considered to 
constitute one of the following: 
1. Recurrence of disease or documented progression of disease (unless continued 
treatment with study drug is deemed appropriate at the discretion of the investigator). 
2. Intercurrent illness that prevents further administration of treatment per investigator 
discretion. 
3. Dose-limiting toxicity (Section 6.2 for definition of DLT). 
4. Any AE that meets criteria for discontinuation as defined in Section 6.3.1, Table 6-1 and 
Table 6-2. 
5. Unacceptable adverse events. 
6. Grade ≥ 3 infusion reaction to durvalumab 
7. Treatment interruption of more than 6 weeks after a scheduled treatment day. 
8. Investigator discontinues treatment. 
9. Initiation of alternative anticancer therapy including another investigational agent. 
10. Pregnancy or intent to become pregnant.

11. Develop a second malignancy (except for non-melanoma skin cancer or cervical 
carcinoma in-situ) that requires treatment, which would interfere with this study. 
12. The patient may choose to withdraw from the study at any time for any reason. 
13. General or specific changes in the patient's condition that render the patient 
unacceptable for further treatment in the judgment of the investigator. 
14. Severe non-compliance to protocol as judged by the investigator. 
15. Lost to follow-up. 
16. Death. 
17. Closure of study by PrECOG. 
Any patient who receives at least one dose of study drug, durvalumab, will be included in 
the safety analysis. Patients who discontinue study treatment early should be followed for 
response assessments, if possible. Follow-up will continue per Section 10, as applicable.

Adverse Event Reporting 
8.1 
Collection of Safety Information 
Adverse Event (AE) is defined as any new untoward medical occurrence or worsening of 
a pre-existing medical condition in a patient administered a medicinal product in a clinical 
investigation and which does not necessarily have a causal relationship with this treatment. 
An AE can therefore be any unfavorable and unintended sign (e.g., including an abnormal 
laboratory finding), symptom, or disease temporally associated with the use of a product 
(investigational or marketed), whether or not considered related to the product 
(investigational or marketed). 
After informed consent, but prior to initiation of study treatment (pemetrexed, cisplatin [or 
carboplatin], and/or durvalumab), only AEs/SAEs caused by a protocol-mandated 
intervention will be collected (e.g., SAEs related to invasive procedures such as biopsies). 
After the initiation of study treatment, all identified AEs and SAEs must be recorded and 
described on the appropriate page of the electronic Case Report Form (eCRF). If known, 
the diagnosis of the underlying illness or disorder should be recorded, rather than individual 
symptoms. The following information should be documented for all AEs: date of onset and 
resolution, severity of the event; the investigator’s opinion of the relationship to 
investigational product (see definitions below); treatment required for the AE treatment 
required for the AE; cause of the event (if known); and information regarding 
resolution/outcome. 
Only clinically significant laboratory abnormalities that require active management will be 
recorded as AEs or SAEs on the eCRF (e.g., abnormalities that require study drug dose 
modification, discontinuation of study treatment, more-frequent follow-up assessments, 
further diagnostic investigation, etc.). 
If the clinically significant laboratory abnormality is a sign of a disease or syndrome (e.g., 
alkaline phosphatase and bilirubin 5x the ULN associated with cholecystitis), only the 
diagnosis (e.g., cholecystitis) needs to be recorded on the Adverse Event eCRF. 
If the clinically significant laboratory abnormality is not a sign of a disease or syndrome, the 
abnormality itself should be recorded as an AE or SAE on the eCRF. If the laboratory 
abnormality can be characterized by a precise clinical term, the clinical term should be 
recorded as the AE or SAE. For example, an elevated serum potassium level of 7.0 mEq/L 
should be recorded as “hyperkalemia”. 
Observations of the same clinically significant laboratory abnormality from visit to visit 
should not be repeatedly recorded as AEs or SAEs on the eCRF unless their severity, 
seriousness, or etiology changes. 
Severity 
The categories and definitions of severity used for clinical trials AEs are defined in the NCI’s 
Common Terminology Criteria (CTCAE) V4.03 (http://ctep.cancer.gov/). 
Attribution 
The following categories and definitions of causal relationship or attribution to study drug 
should be used to assess Adverse Events: 
• Definite: There is a reasonable causal relationship between the study drug and the event. 
The event response to withdrawal of study drug (dechallenge) and recurs with 
rechallenge, if clinically feasible. 
• Probable: There is a reasonable causal relationship between the study drug and the 
event. The event responds to dechallenge. Rechallenge is not required. 
• Possible: There is a reasonable causal relationship between the study drug and the 
event. Dechallenge information is lacking or unclear. 

PrECOG Protocol Number: PrE0505 
Confidential 
Date: 3/19/2018 
 
56 
• Unlikely: There is doubtful causal relationship between the study drug and the event. 
• Unrelated: There is clearly not a causal relationship between the study drug and the 
event or there is a causal relationship between another drug, concurrent disease, or 
circumstances and the event. 
Categories ‘definite’, ‘probable’ and ‘possible’ are considered study drug related. Categories 
‘unlikely’ and ‘unrelated’ are considered not study drug-related. 
The development of a new cancer should be regarded as an AE. New cancers are those 
that are not the primary reason for administration of study treatment and have been 
identified after inclusion of the patient into the clinical study. 
AEs related to pemetrexed and/or cisplatin (or carboplatin) should be followed for 30 
days after last dose of study therapy or until the initiation of alternative anticancer 
therapy until ≤ grade 1 or stabilization, and reported as SAEs if they become serious. 
Any AEs related to durvalumab should be followed for 90 days after last dose of 
durvalumab or until the initiation of alternative anticancer therapy until ≤ grade 1 or 
stabilization, and reported as SAEs if they become serious. 
Any AE’s (serious or not) that occur after the above time periods but are deemed to 
be at least possibly related to study therapy shall be reported. 
8.2 
Definition of Adverse Events of Special Interest (AESI) 
An adverse event of special interest (AESI) is one of scientific and medical interest specific 
to understanding of the Investigational Product and may require close monitoring and rapid 
communication by the investigator to PrECOG. An AESI may be serious or non-serious. 
The rapid reporting of AESIs allows ongoing surveillance of these events in order to 
characterize and understand them in association with the use of this investigational product. 
AESIs for durvalumab include but are not limited to events with a potential inflammatory or 
immune-mediated mechanism and which may require more frequent monitoring and/or 
interventions such as steroids, immunosuppressants and/or hormone replacement therapy. 
These AESIs are being closely monitored in clinical studies with durvalumab monotherapy 
and combination therapy. An immune-mediated adverse event (imAE) is defined as an 
adverse event that is associated with drug exposure and is consistent with an immune-
mediated mechanism of action and where there is no clear alternate etiology. Serologic, 
immunologic, and histologic (biopsy) data, as appropriate, should be used to support an 
imAE diagnosis. Appropriate efforts should be made to rule out neoplastic, infectious, 
metabolic, toxin, or other etiologic causes of the imAE.  
If the Investigator has any questions in regards to an adverse event (AE) being an imAE, 
the Investigator should promptly contact the Study Physician. 
AESIs observed with durvalumab include: 
• 
Colitis 
• 
Pneumonitis/Interstitial Lung Disease (ILD) 
• 
ALT/AST increases/hepatitis/hepatotoxicity  
• 
Neuropathy/neuromuscular toxicity (i.e. events of encephalitis, peripheral motor and 
sensory neuropathies, Guillain-Barré, and myasthenia gravis) 
• 
Endocrinopathy (i.e. events of hypophysitis/hypopituitarism, Type I diabetes mellitus, 
adrenal insufficiency, and hyper- and hypothyroidism) 
• 
Dermatitis/Rash/Pruritis 
• 
Nephritis 
• 
Pancreatitis (or labs suggestive of pancreatitis - increased serum lipase, increased 
serum amylase)

• 
Myocarditis 
• 
Hypersensitivity/Anaphylactic Reactions 
Further information on these risks (e.g. presenting symptoms) can be found in the current 
version of the durvalumab Investigator Brochure. 
8.2.1 
Gastrointestinal Disorders 
Diarrhea/colitis is the most commonly observed treatment emergent SAE when 
tremelimumab is used as monotherapy. In rare cases, colon perforation may occur 
that requires surgery (colectomy) or can lead to a fatal outcome if not properly 
managed. 
Guidelines on management of diarrhea and colitis in patients receiving durvalumab 
are provided in Section 6.3.1, Table 6-1. 
8.2.2 
Pneumonitis 
Adverse events of pneumonitis are of interest as pneumonitis has been reported 
with anti-PD-1 MAbs [47]. Initial work-up should include high-resolution CT scan, 
ruling out infection, and pulse oximetry. Pulmonary consultation is highly 
recommended. 
Guidelines for the management of subjects with immune-mediated events including 
pneumonitis are outlined in Section 6.3.1, Table 6-1. 
8.2.3 
Hepatic Function Abnormalities (Hepatotoxicity) 
Increased transaminases have been reported during treatment with anti-PD-
L1/anti-PD-1 antibodies [48]. Inflammatory hepatitis has been reported in 3% to 9% 
of subjects treated with anti CTLA-4 monoclonal antibodies (e.g., ipilimumab).  The 
clinical manifestations of ipilimumab-treated subjects included general weakness, 
fatigue, nausea and/or mild fever and increased liver function tests such as AST, 
ALT, alkaline phosphatase, and/or total bilirubin. 
Hepatic function abnormality is defined as any increase in ALT or AST to greater 
than 3x ULN and concurrent increase in total bilirubin to be greater than 2x ULN. 
Concurrent findings are those that derive from a single blood draw or from separate 
blood draws taken within 8 days of each other. Follow-up investigations and 
inquiries will be initiated promptly by the investigational site to determine whether 
the findings are reproducible and/or whether there is objective evidence that clearly 
supports causation by a disease (e.g., cholelithiasis and bile duct obstruction with 
distended gallbladder) or an agent other than the investigational product.  
Guidelines for management of subjects with hepatic function abnormality are 
outlined in Section 6.3.1, Table 6-1. 
Cases where a subject shows an AST or ALT ≥ 3x ULN or total bilirubin ≥ 2x ULN 
may need to be reported as SAEs. These cases should be reported as SAEs if, 
after evaluation they meet the criteria for a Hy’s Law case or if any of the individual 
liver test parameters fulfill any of the SAE criteria. 
Criteria for Hy’s Law (FDA Guidance 2009) 
• 
The drug causes hepatocellular injury, generally shown by a higher incidence 
of 3-fold or greater elevations above the ULN of ALT or AST than the 
(non-hepatotoxic) control drug or placebo. 
• 
Among trial subjects showing such aminotransferase elevations, often with 
aminotransferases much greater than 3x ULN, one or more also show elevation 
of serum total bilirubin to >2x ULN, without initial findings of cholestasis 
(elevated serum alkaline phosphatase).

• 
No other reason can be found to explain the combination of increased 
aminotransferases and total bilirubin, such as viral hepatitis A, B, or C; pre-
existing or acute liver disease; or another drug capable of causing the observed 
injury. 
8.2.4 
Neurotoxicity 
Immune-mediated nervous system events include encephalitis, peripheral motor 
and sensory neuropathies, Guillain-Barré, and myasthenia gravis. 
Guidelines for the management of patients with immune-mediated neurotoxic 
events are provided in Section 6.3.1, Table 6-1. 
8.2.5 
Endocrine Disorders 
Immune-mediated endocrinopathies include hypophysitis/hypopituitarism, Type I 
diabetes mellitus, adrenal insufficiency, and hyper- and hypothyroidism. 
Guidelines for the management of patients with immune-mediated endocrine 
events are provided in Section 6.3.1, Table 6-1. 
8.2.6 
Nephritis 
Consult with Nephrologist. Monitor for signs and symptoms that may be related to 
changes in renal function (e.g. routine urinalysis, elevated serum BUN and 
creatinine, decreased creatinine clearance, electrolyte imbalance, decrease in urine 
output, proteinuria, etc.). 
Patients should be thoroughly evaluated to rule out any alternative etiology (e.g., 
disease progression, infections etc.). 
Steroids should be considered in the absence of clear alternative etiology even for 
low grade events (Grade 2), in order to prevent potential progression to higher 
grade event. 
Guidelines for the management of patients with immune-mediated neurotoxic 
events are provided in Section 6.3.1, Table 6-1. 
8.2.7 
Pancreatic Disorders 
Immune-mediated pancreatitis includes autoimmune pancreatitis, and lipase and 
amylase elevation. 
Guidelines for the management of patients with immune-mediated pancreatic 
disorders are provided in Section 6.3.1, Table 6-1. 
8.2.8 
Myocarditis 
Immune-mediated myocarditis includes decreased ejection fraction, arrhythmias, 
and in particular occurrences of atrioventricular block. 
For patients with suspected myocarditis, investigators should obtain a cardiology 
consult and institute full diagnostic work-up (that includes exclusion of other 
alternate causes such as infection) and the appropriate management that includes 
discontinuing drug (permanently if biopsy-proven immune-mediated myocarditis) 
and the prompt use of steroids or other immunosuppressives. Patients with pre-
existing cardiac disorders should be closely monitored for deterioration in their 
cardiac condition, which could suggest new onset myocarditis.

8.2.9 
Hypersensitivity Reactions 
Hypersensitivity reactions as well as infusion-related reactions have been reported 
with anti-PD-L1 and anti-PD-1 therapy [48]. As with the administration of any foreign 
protein and/or other biologic agents, reactions following the infusion of MAbs can 
be caused by various mechanisms, including acute anaphylactic (immunoglobulin 
E-mediated) and anaphylactoid reactions against the MAb, and serum sickness. 
Acute allergic reactions may occur, may be severe, and may result in death. Acute 
allergic reactions may include hypotension, dyspnea, cyanosis, respiratory failure, 
urticaria, pruritus, angioedema, hypotonia, arthralgia, bronchospasm, wheeze, 
cough, dizziness, fatigue, headache, hypertension, myalgia, vomiting and 
unresponsiveness. 
Guidelines for management of subjects with hypersensitivity (including anaphylactic 
reaction) and infusion related reactions are outlined in Section 6.3.1, Table 6-1. 
8.3 
Handling of Serious Adverse Events (SAEs) 
8.3.1 
SAE Definitions 
A serious AE is any untoward medical occurrence occurring after initiation of study 
treatment or that at any dose: 
• 
results in death 
• 
is life-threatening (defined as an event in which the study patient was at risk of 
death at the time of the event; it does not refer to an event which hypothetically 
might have caused death if it were more severe) 
• 
requires inpatient hospitalization or causes prolongation of existing 
hospitalization 
• 
results in persistent or significant disability/incapacity 
• 
is a congenital anomaly/birth defect 
• 
is an important medical event (defined as a medical event(s) that may not be 
immediately life-threatening or result in death or hospitalization but, based upon 
appropriate medical and scientific judgment, may jeopardize the patient or may 
require intervention (e.g., medical, surgical) to prevent one of the other serious 
outcomes listed in the definition above). 
Examples of such events include, but are not limited to, intensive treatment in an 
emergency room or at home for allergic bronchospasm; blood dyscrasias or 
convulsions that do not result in hospitalization. 
8.4 
SAE Reporting Requirements 
Serious adverse events (SAE) are defined above. The investigator should inform PrECOG 
of any SAE within 24 hours of being aware of the event. The date of awareness should be 
noted on the report. This must be documented on the PrECOG SAE form. This form must 
be completed and supplied to PrECOG within 24 hours/1 business day at the latest on the 
following working day. The initial report must be as complete as possible, including details 
of the current illness and (serious) adverse event, and an assessment of the causal 
relationship between the event and the investigational product(s). Information not available 
at the time of the initial report (e.g., an end date for the adverse event or laboratory values 
received after the report) must be documented on a follow-up PrECOG SAE report form. A 
final report to document resolution of the SAE is required. The investigator is responsible 
for following all SAEs until resolution, until the subject returns to baseline status, or until the 
condition has stabilized with the expectation that it will remain chronic, even if this extends 
beyond study participation. A copy of the fax transmission confirmation of the SAE report to 
PrECOG should be attached to the SAE and retained with the patient records. 

PrECOG Protocol Number: PrE0505

All SAEs should be faxed to 888-276-9606 or scanned and emailed to 
PrE0505SAE@qdservices.com as per the instructions found in study materials provided 
to the investigator site.

PrECOG will notify AstraZeneca of all SAE’s within 24 hours of PrECOG’s Awareness Date 
as discussed above. Relevant follow-up information will be provided to AstraZeneca as soon 
as it becomes available. 
Investigators should also report event(s) to their IRB as required. 
Collection of complete information concerning SAEs is extremely important. Full 
descriptions of each event will be followed. Thus, follow-up information which becomes 
available as the SAE evolves, as well as supporting documentation (e.g., hospital discharge 
summaries and autopsy reports), should be collected subsequently, if not available at the 
time of the initial report, and immediately sent using the same procedure as the initial SAE 
report. 
All SAEs, regardless of causality (Section 8.4.1 for additional information for hepatic function 
abnormality) must be collected which occur within 90 days of last dose of durvalumab or 
until the initiation of alternative anticancer therapy. This includes all deaths within 90 days 
of last dose of durvalumab, unless related to progression of disease (disease progression 
will be documented, but not reported as an SAE). After 90 days, patients with ongoing 
durvalumab-related SAEs will be continued to be followed for safety. 
In addition, if a subject discontinues from treatment for reasons other than disease 
progression, and therefore continues to have tumor assessments, durvalumab-related 
SAEs must be captured until the patient is considered to have confirmed PD and will have 
no further tumor assessments. 
The Investigator should notify PrECOG or designee of any SAE that may occur after the 
above time period which they believe to be definitely, probably or possibly related to 
investigational product. 
NOTE: 
After study closure, study-drug related SAEs should be reported voluntarily by the 
treating physician to the manufacturer. 
Serious adverse event reporting to regulatory authorities and all participating investigators 
will be conducted by PrECOG (or designee) in accordance with 21CFR312.32, local 
requirements and international regulations, as appropriate. FDA reporting requirement 
timelines will be followed. PrECOG will also concurrently forward any such reports to 
AstraZeneca. 
8.4.1 
Hepatic Function Abnormality 
Hepatic function abnormality (as defined in Section 8.2.3) in a study subject, with 
or without associated clinical manifestations, is required to be reported as “hepatic 
function abnormal” within 24 hours of knowledge of the event as noted above, 
unless a definitive underlying diagnosis for the abnormality (e.g., cholelithiasis or 
bile duct obstruction) that is unrelated to investigational product has been 
confirmed.

• 
If the definitive underlying diagnosis for the abnormality has been established 
and is unrelated to investigational product, the decision to continue dosing of 
the study subject will be based on the clinical judgment of the investigator. 
• 
If no definitive underlying diagnosis for the abnormality is established, dosing 
of the study subject must be interrupted immediately. Follow-up investigations 
and inquiries must be initiated by the investigational site without delay. 
Each reported event of hepatic function abnormality will be followed by the 
investigator and evaluated by PrECOG. 
8.5 
Reporting of Other Second Primary Cancers 
New cancers are those that are not the primary reason for administration of study treatment 
and have been identified after inclusion of the patient into the clinical study. 
All cases of new primary cancers that occur during or after protocol treatment must be 
reported to PrECOG on a Second Primary Cancer form within 30 days of diagnosis, 
regardless of relationship to protocol treatment. Secondary primary malignancies should 
also be reported as a SAE. The SAE form is not for use for reporting recurrence or 
development of metastatic disease. A copy of the pathology report, if applicable, should be 
sent, if available. 
NOTE: 
Once data regarding survival and remission status are no longer required by the 
protocol, no follow-up data should be submitted. 
8.6 
Procedures in Case of Pregnancy 
Prior to study enrollment, women of childbearing potential (WOCBP) and male patients with 
a female partner of childbearing potential must be advised of the importance of avoiding 
pregnancy during trial participation and the potential risk factors for an unintentional 
pregnancy, documented in the informed consent. 
8.6.1 
Maternal Exposure 
If a patient becomes pregnant during the course of the study, the study drugs should 
be discontinued immediately. 
Pregnancy itself is not regarded as an AE unless there is a suspicion that the study 
drugs may have interfered with the effectiveness of a contraceptive medication. 
Congenital abnormalities or birth defects and spontaneous miscarriages should be 
reported and handled as SAEs. Elective abortions without complications should not 
be handled as AEs. The outcome of all pregnancies (spontaneous miscarriage, 
elective termination, ectopic pregnancy, normal birth, or congenital abnormality) 
should be followed up and documented even if the patient was discontinued from 
the study. 
If any pregnancy occurs in the course of the study, then the Investigator or other 
site personnel should inform PrECOG within 1 day, i.e., immediately, but no later 
than 24 hours of when he or she becomes aware of it. 
PrECOG will work with the Investigator to ensure that all relevant information is 
provided to PrECOG within 1 to 5 calendar days for SAEs and within 30 days for all 
other pregnancies. 
The same timelines apply when outcome information is available. 
8.6.2 
Paternal Exposure  
Male patients should refrain from fathering a child or donating sperm during the 
study and for 90 days after the last dose of durvalumab. 

PrECOG Protocol Number: PrE0505

Pregnancy of the patient’s partner is not considered to be an AE. However, the 
outcome of all pregnancies (spontaneous miscarriage, elective termination, ectopic 
pregnancy, normal birth, or congenital abnormality) occurring from the date of the 
first dose until 90 days after the last dose should, if possible, be followed up and 
documented. 
Where a report of pregnancy is received, prior to obtaining information about the 
pregnancy, the Investigator must obtain the consent of the patient’s partner.  
Therefore, the local study team should adopt the generic ICF template in line with 
local procedures and submit it to the relevant Ethics Committees (ECs)/Institutional 
Review Boards (IRBs) prior to use. 
8.7 
Durvalumab Overdose 
An overdose is defined as a subject receiving a dose of durvalumab in excess of that 
specified in the Investigator’s Brochure, unless otherwise specified in this protocol. 
Any overdose of a study subject with durvalumab, with or without associated AEs/SAEs, is 
required to be reported within 24 hours of knowledge of the event to PrECOG. If the 
overdose results in an AE, the AE must also be recorded as an AE (Section 8.1). Overdose 
does not automatically make an AE serious, but if the consequences of the overdose are 
serious, for example death or hospitalization, the event is serious and must be recorded and 
reported as an SAE (Section 8.4). There is currently no specific treatment in the event of an 
overdose of durvalumab. 
The investigator will use clinical judgment to treat any overdose either of durvalumab or the 
chemotherapeutic agents used to treat patients enrolled in this protocol.

Measurement of Effect 
9.1 
Solid Tumor Response Criteria (RECIST Version 1.1) 
9.1.1 
Malignant Disease Evaluation 
Response and progression will be evaluated in this study using the international 
criteria proposed by the revised Response Evaluation Criteria in Solid Tumors 
(RECIST) guideline Version 1.1 with standard modifications used in the evaluation 
of mesothelioma [42, 49-50]. Changes in the largest diameter (unidimensional 
measurement) of the tumor lesions and the shortest diameter in the case of 
malignant lymph nodes are used in RECIST. 
To assess objective response, it is necessary to estimate the overall tumor burden 
at baseline to which subsequent measurements will be compared. Measurable 
disease is defined by the presence of at least one measurable lesion. 
All measurements should be recorded in metric notation by use of a ruler or calipers. 
The same method of assessment and the same technique should be used to 
characterize each identified lesion at baseline and during follow-up. All baseline 
evaluations should be performed as closely as possible to the beginning of 
treatment and never more than four weeks before registration. 
The term evaluable in reference to measurability will not be used because it does 
not provide additional meaning or accuracy. 
At baseline, tumor lesions will be characterized as either measurable or non-
measurable. 
9.1.1.1 
Measurable 
Measurable tumor lesions are those that can be accurately measured 
in at least one dimension (longest diameter in the plane of 
measurement is to be recorded) with a minimum size of: 
• 
≥ 10 mm by CT scan (irrespective of scanner type) and MRI (no 
less than double the slice thickness and a minimum of 10 mm) 
• 
≥ 10 mm caliper measurement by clinical exam (when superficial) 
• 
≥ 20 mm by chest x-ray (if clearly defined and surrounded by 
aerated lung) 
If the measurable disease is restricted to a solitary lesion, its neoplastic 
nature should be confirmed by cytology/histology. 
9.1.1.2 
Malignant Lymph Nodes 
To be considered pathologically enlarged and measurable, a lymph 
node must be ≥ 15 mm in short axis (perpendicular to longest diameter) 
when assessed by CT scan. 
9.1.1.3 
Non-Measurable 
All other lesions (or sites of disease), including small lesions not 
meeting the criteria in 9.1.1.1 and 9.1.1.2, are considered non-
measurable lesions. This includes lymph nodes measured at ≥ 10 to 
<15 mm in the short axis. NOTE: Lymph nodes measured at <10 mm 
in the short axis are considered normal. 
Lesions considered to be non-measurable include the following: 
leptomeningeal 
disease, 
ascites, 
pleural/pericardial 
effusions, 
inflammatory breast disease, lymphangitic involvement of the skin or 
lung, and abdominal masses/abdominal organomegaly identified by 

PrECOG Protocol Number: PrE0505

64 
physical exam that is not measurable by reproducible imaging 
techniques. 
NOTE: 
‘Cystic lesions’ that meet the criteria for radiographically 
defined simple cysts 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 non-cystic lesions are 
present in the same patient, these are preferred for selection as target 
lesions. 
Lytic bone lesions, with an identifiable soft tissue component, evaluated 
by CT or MRI, can be considered as measurable lesions if the soft 
tissue component otherwise meets the definition of measurability in 
Section 9.1.1.1. Blastic bone lesions are non-measurable. 
Tumor lesions that are situated in a previously irradiated area, or in an 
area subjected to other loco-regional therapy, are usually not 
considered measurable unless there has been demonstrated 
progression in the lesion. 
9.1.2 
Definitions of Response 
9.1.2.1 
Target Lesions 
All measurable lesions up to a maximum of 2 lesions per organ and 5 
lesions in total, 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 (those with 
the longest diameters), be representative of all involved organs, but in 
addition should be those that lend themselves to reproducible repeated 
measurements. It may be the case that, on occasion, the largest lesion 
does not lend itself to reproducible measurement in which 
circumstance the next largest lesion which can be measured 
reproducibly should be selected. 
The sum of the target lesions (longest diameter for non-nodal lesions, 
short axis for nodal lesions) will be calculated and reported as the 
baseline sum. If lymph nodes are to be included in the sum, then only 
the short axis is added into the sum. The baseline sum of the 
diameters/axes will be used as reference to further characterize any 
objective tumor regression in the measurable dimension of the disease. 
Complete Response (CR) 
The disappearance of all target lesions. Any pathological lymph nodes 
(whether target or non-target) must have reduction in short axis to 
<10 mm (the sum may not be “0” if there are target nodes). To be 
assigned a status of complete response, changes in tumor 
measurements must be confirmed by repeat assessments performed 
≥ 4 weeks after the criteria for response are first met. 
Partial Response (PR) 
At least a 30% decrease in the sum of the diameters/axes of target 
lesions, taking as reference the baseline sum diameters/axes. To be 
assigned a status of partial response, changes in tumor measurements 

PrECOG Protocol Number: PrE0505 
Confidential 
Date: 3/19/2018 
 
65 
must be confirmed by repeat assessments performed ≥ 4 weeks after 
the criteria for response is met. 
Progressive Disease (PD) 
At least a 20% increase in the sum of the diameters/axes of target 
lesions, taking as reference the smallest sum on study (this includes 
the baseline sum if that is the smallest on study). In addition to the 
relative increase of 20%, the sum must also demonstrate an absolute 
increase of at least 5 mm over the nadir. (NOTE: the appearance of 
one or more new lesions is also considered progression). 
Please refer to Section 9.1.5 for Immune-Related Response for 
guidance. 
Stable Disease (SD) 
Neither sufficient shrinkage to qualify for PR nor sufficient increase to 
qualify for PD, taking as reference the smallest sum diameters/axes 
while on study. (NOTE: a change of 20% or more that does not 
increase the sum of the diameters by 5 mm or more is coded as stable 
disease). 
To be assigned a status of stable disease, measurements must have 
met the stable disease criteria at least once after study entry at a 
minimum interval of ≥ 4 weeks. 
9.1.2.2 
Non-Target Lesions 
All other lesions or sites of disease including any measurable lesions 
over and above the 5 target lesions and lymph nodes measured at ≥ 10 
to <15 mm in the short axis should be identified as non-target lesions 
and should also be recorded at baseline. Measurements of these 
lesions are not required, but the presence or absence of unequivocal 
progression of each should be noted throughout follow-up. 
Complete Response (CR) 
The disappearance of all non-target lesions and normalization of tumor 
marker levels, if applicable. All lymph nodes must be non-pathological 
in size (<10 mm short axis). To be assigned a status of complete 
response, changes in tumor measurements must be confirmed by 
repeat assessments performed ≥ 4 weeks after the criteria for response 
are first met. 
NOTE: 
If tumor markers are initially above the upper normal limit, 
they must normalize for a patient to be considered in 
complete clinical response. 
Non-CR/Non-PD 
The persistence of one or more non-target lesion(s) and/or the 
maintenance of tumor marker levels above the normal limits. To be 
assigned a status of Non-CR/Non-PD, measurements must have met 
the Non-CR/Non-PD criteria at least once after study entry at a 
minimum interval of ≥ 4 weeks. 
Progressive Disease (PD) 
The appearance of one or more new lesion(s) and/or unequivocal 
progression of existing non-target lesions. Unequivocal progression 
should not normally trump target lesion status. It must be 

PrECOG Protocol Number: PrE0505 
Confidential 
Date: 3/19/2018 
 
66 
representative of overall disease status change, not a single lesion 
increase. 
When the patient also has measurable disease, there must be an 
overall level of substantial worsening in non-target disease such that, 
even in the presence of SD or PR in target disease, the overall tumor 
burden has increased sufficiently to merit discontinuation of therapy. A 
modest “increase” in the size 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 SD or PR of target disease will therefore 
be extremely rare. 
When the patient only has non-measurable disease, the increase in 
overall disease burden should be comparable in magnitude to the 
increase that would be required to declare PD for measurable disease: 
i.e., an increase in tumor burden from “trace” to “large”, an increase in 
nodal disease from “localized” to “widespread”, or an increase sufficient 
to require a change in therapy. 
Although a clear progression of “non-target” lesions only is exceptional, 
the opinion of the treating physician should prevail in such 
circumstances. 
Please refer to Section 9.1.5 for Immune-Related Response for 
guidance. 
9.1.3 
Evaluation of New Lesions 
The appearance of new lesions constitutes Progressive Disease (PD) however this 
should lead to clinical evaluation as guided by Section 9.1.5 below. 
9.1.4 
Symptomatic Deterioration 
Patients with a global deterioration of health status requiring discontinuation of 
treatment without objective evidence of disease progression at that time should be 
reported as “symptomatic deterioration”. Every effort should be made to document 
the objective progression even after discontinuation of treatment. 
9.1.5 
Immune-Related Response 
The response to immunotherapy may differ from the typical responses observed 
with cytotoxic chemotherapy including the following [51, 52]: 
• 
Response to immunotherapy may be delayed. 
• 
Response to immunotherapy may occur after PD by conventional criteria. 
• 
The appearance of new lesions may not represent PD with immunotherapy. 
• 
SD while on immunotherapy may be durable and represent clinical benefit. 
Based on the above-described unique response to immunotherapy and based on 
guidelines from regulatory agencies, e.g., European Medicines Agency’s “Guideline 
on 
the 
evaluation 
of 
anti-cancer 
medicinal 
products 
in 
man” 
(EMA/CHMP/205/95/Rev.4) [53] for immune modulating anti-cancer compounds, 
the study will implement the following in addition to standard RECIST 1.1 criteria: 
• 
RECIST will be modified so that PD must be confirmed at the next scheduled 
visit, preferably, and no earlier than 4 weeks after the initial assessment of PD 
in the absence of clinically significant deterioration. Treatment with durvalumab 
would continue between the initial assessment of progression and confirmation 
for progression. 

PrECOG Protocol Number: PrE0505 
Confidential 
Date: 3/19/2018 
 
67 
• 
In addition, subjects may continue to receive durvalumab beyond confirmed PD 
in the absence of clinically significant deterioration and if investigators consider 
that subjects continue to receive benefit from treatment. 
Modification of RECIST as described may discourage the early discontinuation of 
durvalumab and provide a more complete evaluation of its anti-tumor activity than 
would be seen with conventional response criteria. Nonetheless, the efficacy 
analysis will be conducted by programmatically deriving each efficacy endpoint 
based on RECIST 1.1 criteria modified for mesothelioma. 
Of note, clinically significant deterioration is considered to be a rapid tumor 
progression that necessitates treatment with anti-cancer therapy other than 
durvalumab or with symptomatic progression that requires urgent medical 
intervention (e.g., symptomatic central nervous system metastasis, respiratory 
failure due to tumor compression, spinal cord compression). 
9.2 
Evaluation of Patient’s Best Overall Response 
The best overall response is the best response recorded from the start of the treatment until 
confirmed disease progression or non-protocol therapy (taking as reference for progressive 
disease the smallest measurements recorded since the treatment started). Assessment of 
best overall response should allow for immune-related response patterns as described in 
Section 9.1.5. The patient's best response assignment will depend on the achievement of 
both measurement and confirmation criteria (Table 9-1). 
To be assigned a status of complete or partial response, changes in tumor measurements 
must be confirmed by repeat assessments performed ≥ 4 weeks after the criteria for 
response are first met. 
To be assigned a status of stable disease, measurements must have met the stable disease 
criteria at least once after study entry at a minimum interval of ≥ 4 weeks.

NOTE: 
If subjects respond to treatment and are able to have their disease resected; the 
patient’s response will be assessed prior to the surgery. However, the patient will 
be considered inevaluable for survival analysis. 
9.2.1 
Methods of Measurement 
Imaging based evaluation is preferred to evaluation by clinical examination. The 
same imaging modality should be used throughout the study to measure disease 
(preferred but not mandated). 
9.2.1.1 
Clinical Lesions 
Clinical lesions will only be considered measurable when they are 
superficial (e.g., skin nodules and palpable lymph nodes) and ≥ 10 mm 
in diameter as assessed using calipers (e.g., skin nodules). In the case 
of skin lesions, documentation by color photography, including a ruler 
to estimate the size of the lesion, is recommended. 
9.2.1.2 
CXR 
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. 
9.2.1.3 
CT and MRI 
This guideline has defined measurability of lesions on CT scan based 
on the assumption that CT slice thickness is 5 mm or less. If CT scans 
have slice thickness greater than 5 mm, the minimum size for a 
measurable lesion should be twice the slice thickness. MRI is also 
acceptable in certain situations (e.g. for body scans). 
Use of MRI remains a complex issue. MRI has excellent contrast, 
spatial, and temporal resolution; however, there are many image 
acquisition variables involved in MRI which greatly impact image 
quality, lesion conspicuity, and measurement. Furthermore, the 
availability of MRI is variable globally. As with CT, if an MRI is 
performed, the technical specifications of the scanning sequences 
used should be optimized for the evaluation of the type and site of 
disease. Furthermore, as with CT, the modality used at follow-up 
should be the same as was used at baseline and the lesions should be 
measured/assessed on the same pulse sequence. It is beyond the 
scope of the RECIST guidelines to prescribe specific MRI pulse 
sequence parameters for all scanners, body parts, and diseases. 
Ideally, the same type of scanner should be used and the image 
acquisition protocol should be followed as closely as possible to prior 
scans. Body scans should be performed with breath-hold scanning 
techniques, if possible. 
9.2.1.4 
PET-CT 
At present, the low dose or attenuation correction CT portion of a 
combined PET-CT is not always of optimal diagnostic CT quality for 
use with RECIST measurements. However, if the site can document 
that the CT performed as part of a PET-CT is of identical diagnostic 
quality to a diagnostic CT (with IV and oral contrast), then the CT 
portion of the PET-CT can be used for RECIST measurements and can 
be used interchangeably with conventional CT in accurately measuring 
cancer lesions over time. Note, however, that the PET portion of the

CT introduces additional data which may bias an investigator if it is not 
routinely or serially performed. 
9.2.1.5 
Ultrasound 
Ultrasound is not useful in assessment of lesion size and should not be 
used as a method of measurement. Ultrasound examinations cannot 
be reproduced in their entirety for independent review at a later date 
and, because they are operator dependent, it cannot be guaranteed 
that the same technique and measurements will be taken from one 
assessment to the next. If new lesions are identified by ultrasound in 
the course of the study, confirmation by CT or MRI is advised. If there 
is concern about radiation exposure at CT, MRI may be used instead 
of CT in selected instances. 
9.2.1.6 
Endoscopy, Laparoscopy 
The utilization of these techniques for objective tumor evaluation is not 
advised. However, such techniques may be useful to confirm complete 
pathological response when biopsies are obtained or to determine 
relapse in trials where recurrence following CR or surgical resection is 
an endpoint. 
9.2.1.7 
Tumor Markers 
Tumor markers alone cannot be used to assess response. If markers 
are initially above the upper normal limit, they must normalize for a 
patient to be considered in complete clinical response. 
9.2.1.8 
Cytology, Histology 
These techniques can be used to differentiate between PR and CR in 
rare cases (e.g., residual lesions in tumor types, such as germ cell 
tumors, where known residual benign tumors can remain). 
The cytological confirmation of the neoplastic origin of any effusion that 
appears or worsens during treatment when the measurable tumor has 
met criteria for response or SD is mandatory to differentiate between 
response or SD (an effusion may be a side effect of the treatment) and 
PD.

14 Pre-treatment, diagnostic pathology specimens obtained in the course of standard biopsy or surgery. Formalin-Fixed Paraffin-Embedded (FFPE) block 
(preferred) or a minimum of 15 FFPE unstained sections of 5 micron thickness plus 1 H&E slide will be required. Procurement of tissue will be mandatory for 
enrollment. Submit tumor sample (block or slides) within 3 months of patient registration. See Section 13.1 and 13.3 for details. 
15 Research bloods are to be drawn prior to treatment on C1D1, prior to treatment on C2D1, and prior to treatment on C5D1 of concurrent therapy or at time of 
confirmed progression IF confirmed progression occurs before Cycle 5, Day 1. 
At each time point, collect one (1) 10 mL EDTA tube and two (2) 10 mL Streck tubes. EDTA tube must be collected before the Streck tubes. Details of 
blood specimen handling and shipping are provided in the lab manual. See Section 13.1 and 13.4 for details. 
16 Patients will receive durvalumab 1120 mg, pemetrexed 500 mg/m2 and cisplatin 75 mg/m2 (or carboplatin AUC 5) by IV infusion on days 1 of each 21 
day cycle (1 cycle=21 days). Up to 6 cycles (6 doses) of concurrent therapy will be administered. See Section 6.1 for administration and re-treatment guidelines 
and Section 6.3.1, Table 6-1 and Table 6-2 for dose modifications for durvalumab and Section 6.1 for administration and re-treatment guidelines and Section 
6.3.2 and Table 6-3 for dose modifications/reductions for pemetrexed and cisplatin (or carboplatin). Patients must have at least 2 cycles of pemetrexed/cisplatin 
(or carboplatin) with durvalumab in order to be eligible to proceed to maintenance durvalumab (Section 6.3.2 for additional guidelines). 
NOTE: Oral folic acid 350 to 1000 µg daily should be given starting 1 week prior to the first dose of pemetrexed, with at least 5 doses of folic acid administered 
in the 7 days prior to the first dose. Oral folic acid should be continued daily throughout the treatment with pemetrexed and for 21 days after the last 
dose of pemetrexed has been administered. Intramuscular (IM) injection of Vitamin B12 1000 µg should be given approximately one week prior to 
the first dose of pemetrexed and repeated on the day that the third and sixth pemetrexed treatment is administered. Oral folic acid and Vitamin B12 
injection may also be given per local standard of care. 
17 Palliative radiation may be given as clinically indicated and must start at least one week after dose of pemetrexed/cisplatin and durvalumab or must be 
completed one week before next dose of pemetrexed/cisplatin and durvalumab. 
18 Review of prior/concomitant medication taken 14 days prior to informed consent and continues until completion of study treatment. 
19 Beginning with Cycle 1 radiographic response will be assessed with imaging every 6 weeks until completion of concurrent phase of treatment. In the setting 
of progressive disease on a single tumor assessment, patients will be made aware of the potential benefits and risks of continuing the study regimen in the 
setting of PD by providing separate written informed consent (Section 9.1.5 for criteria for treatment beyond progression). 
20 If more than 4 weeks since last scan, repeat MRI and/or CT to confirm disease status/progression. If patient is removed from treatment for reason(s) other 
than progression, follow with regular tumor assessments per standard of care until progression or start of new treatment. 
21 Patients will be followed for adverse events related to cisplatin (or carboplatin) and/or pemetrexed for 30 days after their last dose of study therapy or for 90 
days after their last dose of durvalumab or until the initiation of alternative anticancer therapy. 
22 Every 3 months from treatment discontinuation until death or study closure. Initiation of any other anti-cancer therapies will also be documented.

Drug Formulation and Procurement 
11.1 
Durvalumab 
11.1.1 Other Names 
Also known as MEDI4736. 
11.1.2 Classification 
Human IgG1κ monoclonal antibody. 
11.1.3 Mode of Action 
 
 
 
11.1.4 Storage 
Unopened vials of MEDI4736 lyophilized or liquid Drug Product must be stored at 2°C 
to 8°C (36°F to 46°F) and must not be frozen. 
11.1.5  Dose Specifics 
A fixed dose of 1120 mg q 3 weeks durvalumab will be used in this study. 
For patients weighing ≥ 30 kg, a fixed dose of 1120 mg Q3W durvalumab (equivalent 
to 15 mg/kg Q3W based on an average body weight of 75 kg) should be prepared. 
Patients <30 kg body weight should be discussed with PrECOG before considering 
patient for enrollment. 
Refer to Section 6.3.1 and Table 6-1 and Table 6-2 for Dose Delays and Modifications 
details. 
11.1.6 Preparation 
Durvalumab will be supplied by AstraZeneca as a 500 mg vial solution for infusion 
after dilution.
 
 
 The nominal fill volume is 10 mL Investigational 
product vials are stored at 2°C to 8°C (36°F to 46°F) and must not be frozen. 
Durvalumab must be used within the individually assigned expiry date on the label. 
Preparation of Durvalumab Doses for Administration with an IV Bag 
The dose of durvalumab for administration must be prepared using aseptic technique. 
Total time from needle puncture of the durvalumab vial to the start of administration 
should not exceed: 
• 
24 hours at 2°C to 8°C (36°F to 46°F) 
• 
4 hours at room temperature 
If in-use storage time exceeds these limits, a new dose must be prepared from new 
vials. Infusion solutions must be allowed to equilibrate to room temperature prior to 
commencement of administration. 
No incompatibilities between durvalumab and polyvinylchloride or polyolefin IV bags 
have been observed. Dose of 1120 mg durvalumab for patient’s ≥ 30 kg will be 
administered using an IV bag containing 0.9% (w/v) saline with a final durvalumab 
concentration ranging from 1 to 20 mg/mL, and delivered through an IV administration 
set with a 0.2- or 0.22-μm in-line filter. 

PrECOG Protocol Number: PrE0505 
Confidential 
Date: 3/19/2018 
 
77 
Remove a volume of IV solution from the IV bag equal to the calculated volume of 
durvalumab to be added to the IV bag prior to addition of durvalumab. Next, the volume 
of durvalumab (i.e., 15.0 mL for 750 mg or 30.0 mL for 1500 mg of durvalumab) is 
added to the IV bag such that final concentration is within 1 to 20 mg/mL (IV bag 
volumes 100 to 1000 mL). Mix the bag by gently inverting to ensure homogeneity of 
the dose in the bag. 
11.1.7 Route of Administration 
Durvalumab will be administered at room temperature (approximately 25°C) by 
controlled infusion via an infusion pump into a peripheral or central vein. Following 
preparation of durvalumab, the entire contents of the IV bag should be administered 
as an IV infusion over approximately 60 minutes (±5 minutes), using a 0.2, or 0.22-μm 
in-line filter. Less than 55 minutes is considered a deviation. 
The IV line will be flushed with a volume of IV solution (0.9% [w/v] saline) equal to the 
priming volume of the infusion set used after the contents of the IV bag are fully 
administered, or complete the infusion according to institutional policy to ensure the 
full dose is administered and document if the line was not flushed. 
Standard infusion time is 1 hour. However, if there are interruptions during infusion, the 
total allowed time should not exceed 8 hours at room temperature. The table below 
summarizes time allowances and temperatures. 
Table 11-1 
Durvalumab Hold and Infusion Times 
Maximum time from needle puncture to 
start of administration 
4 hours at room temperature, 24 hours 
at 2°C to 8°C 
Maximum time for IV bag infusion, 
including interruptions 
8 hours at room temperature 
In the event that either preparation time or infusion time exceeds the time limits outlined 
above, a new dose must be prepared from new vials. Durvalumab does not contain 
preservatives, and any unused portion must be discarded. 
11.1.8 Monitoring of Dose Administration 
Subjects will be monitored before, during and after the infusion with assessment of 
vital signs at the times specified in Section 10. Subjects are monitored (pulse rate, 
blood pressure) every 30 minutes during the infusion period (including times where 
infusion rate is slowed or temporarily stopped). 
11.1.9 Management of Infusion Reaction 
In the event of a ≤ Grade 2 infusion-related reaction, the infusion rate of study drug 
may be decreased by 50% or interrupted until resolution of the event (up to 4 hours) 
and re-initiated at 50% of the initial rate until completion of the infusion. For subjects 
with a ≤ Grade 2 infusion related reaction, subsequent infusions may be administered 
at 50% of the initial rate. Acetaminophen and/or an antihistamine (e.g., 
diphenhydramine) or equivalent medications per institutional standard may be 
administered at the discretion of the investigator. Steroids should not be used for 
routine premedication of ≤ Grade 2 infusion related reactions. 
If the infusion related reaction is Grade 3 or higher in severity, study drug will be 
discontinued. 
The standard infusion time is one hour, however if there are interruptions during 
infusion, the total allowed time from infusion start to completion of infusion should not 
exceed 4 hours at room temperature, with maximum total time at room temperature 
not exceeding 4 hours (otherwise requires new infusion preparation).

As with any antibody, allergic reactions to dose administration are possible. 
Appropriate drugs and medical equipment to treat acute anaphylactic reactions must 
be immediately available, and study personnel must be trained to recognize and treat 
anaphylaxis. The study site must have immediate access to emergency resuscitation 
teams and equipment in addition to the ability to admit subjects to an intensive care 
unit if necessary. 
11.1.10 Availability 
Durvalumab will be supplied by AstraZeneca as a 500-mg vial solution for infusion 
after dilution. 
The initial supply of durvalumab will be sent directly to the site upon site activation. As 
needed, durvalumab may be requested by the PI (or their authorized designees) at 
each participating institution. The investigator, or a responsible party designated by 
the investigator, must maintain a careful record of the receipt, disposition, and 
return/destruction (site’s drug destruction policy must be reviewed and approved by 
PrECOG before any study drug can be destroyed at a site) of durvalumab. 
11.1.11 Agent Ordering 
PrECOG will be responsible for ordering drug for re-supply to the site. Requests for 
shipments of durvalumab will be coordinated between PrECOG and AstraZeneca. 
11.1.12 Agent Accountability 
Durvalumab will be stored in a secure location. Only authorized pharmacy and study 
staff will have access to this agent. Drug accountability will be performed by PrECOG.

Pemetrexed [36] and Cisplatin [37] 
NOTE: 
Pemetrexed and Cisplatin (carboplatin may be substituted for cisplatin as 
described in Section 3.9 and Section 5.1) will be obtained by the individual study 
sites as standard of care treatments from commercial stock. Refer to commercial 
package inserts for full prescribing information. 
11.2.1 Other Names 
Pemetrexed - Alimta® 
Cisplatin – Platinol® 
Carboplatin [38] – Paraplatin® 
11.2.2 Classification 
Pemetrexed is a folate analog metabolic inhibitor indicated for the treatment of 
mesothelioma in combination with cisplatin. 
Cisplatin and Carboplatin are alkylating agents that appear to form intra- and inter-
strand crosslinks in cells which modifies DNA structure and inhibits DNA synthesis. 
11.2.3 Storage and Stability 
Please consult the prescribing information for Pemetrexed, Cisplatin and Carboplatin. 
11.2.4 Dose Specifics 
Recommended dose of pemetrexed is 500 mg/m2 IV on Day 1 of each 21-day cycle in 
combination with cisplatin 75 mg/m2 IV beginning 30 minutes after pemetrexed 
administration (or per investigator discretion and local standard-of-care). 
If carboplatin is substituted for cisplatin per Section 3.9 or Section 5.1, the recommend 
dose of Carboplatin is AUC of 5 on Day 1 of each 21-day cycle beginning 15-30

minutes after pemetrexed administration (or per investigator discretion and local 
standard-of-care).. 
11.2.5 Preparation 
Pemetrexed and cisplatin (or carboplatin) will be prepared as per the institutional 
standards. 
11.2.6 Route of Administration 
The recommended dose of pemetrexed is 500 mg/m2 administered as an intravenous 
infusion over 10 minutes (or per investigator discretion and local standard-of-care) on 
Day 1 of each 21-day cycle. 
During concurrent treatment days, pemetrexed infusion will begin approximately 
30 minutes after the infusion of durvalumab has finished (or per investigator 
discretion and local standard-of-care). 
The recommended dose of cisplatin is 75 mg/m2 infused over 2 hours beginning 
approximately 30 minutes after the end of pemetrexed administration (or per 
investigator discretion and local standard-of-care). Patients should receive appropriate 
hydration prior to and/or after receiving cisplatin. Hydration may commence prior to or 
concurrently with durvalumab. See cisplatin package insert for more information. 
If carboplatin is substituted for cisplatin per Section 3.9 or Section 5.1, the 
recommended dose of carboplatin is AUC 5 infused over 30 minutes beginning 
approximately 15-30 minutes after the end of the pemetrexed administration (or per 
investigator discretion and local standard-of-care). 
CALVERT FORMULA FOR CARBOPLATIN DOSING 
Total Dose (mg) = (target AUC) x (CrCL by Cockcroft-Gault [Appendix II] + 25) 
NOTE: 
With the Calvert formula, the total dose of PARAPLATIN is calculated in 
mg, not mg/m2. 
11.2.7 Incompatibilities 
Please consult the prescribing information for Pemetrexed, Cisplatin and Carboplatin. 
11.2.8 Premedication Regimen – Pemetrexed 
Oral corticosteroid should be given according to local standards at a dose equivalent 
to dexamethasone 4 mg BID on the day prior to, the day of, and the day after the 
administration of pemetrexed. Oral folic acid 350 to 1000 µg daily should be given 
starting 1 week prior to the first dose of pemetrexed, with at least 5 doses of folic acid 
administered in the 7 days prior to the first dose. Oral folic acid should be continued 
daily throughout the treatment with pemetrexed and for 21 days after the last dose of 
pemetrexed has been administered. Intramuscular (IM) injection of Vitamin B12 1000 
µg should be given approximately one week prior to the first dose of pemetrexed and 
repeated on the day that the third and sixth pemetrexed treatment is administered. 
Oral folic acid and Vitamin B12 injection may also be given per local standard of care. 
11.2.9 Premedication Regimen – Cisplatin 
Cisplatin will be administered to patients at least 30 minutes following the end of the 
pemetrexed infusion. Pretreatment hydration for cisplatin can follow local standard of 
care or use of 1 to 2 liters of fluid (per local standards) infused IV for 2-4 hours prior to 
cisplatin infusion is recommended. Adequate hydration and urinary output must be 
maintained for at least 24 hours following cisplatin administration. Administration and 
monitoring should be performed according to local standards. Use of mannitol 
following the cisplatin infusion should also follow local standard-of-care.

Statistical Considerations 
12.1 
Study Design & Sample Size Considerations – Safety Run-In 
12.1.1 Study Design and Objectives – Initial Six Patients Enrolled 
It is planned to enroll a total of 55 patients (50 expected to receive treatment) on this 
study, the first six patients enrolled will be monitored for safety of the combination of 
durvalumab with pemetrexed/cisplatin (or carboplatin). Standard induction with 
pemetrexed/cisplatin (or carboplatin) will be given for six 3-week cycles with the 
addition of concurrent durvalumab dosed at 1120 mg every 3 weeks. After completion 
of Cycle 6 of concurrent therapy, patients with stable or responding disease per 
modified RECIST for malignant mesothelioma will continue on single agent 
durvalumab at the same dose every 3 weeks until disease progression or a maximum 
duration of 12 months of durvalumab starting from Cycle 1 of concurrent treatment. 
The initial 6 patients completed 2 cycles of concurrent therapy with no DLTs. 
12.1.2 Statistical Analysis Plan for Safety 
This study will initially enroll 6 patients (from the total of 50 patients expected to enroll 
and receive treatment) to the combination of pemetrexed/cisplatin (or carboplatin) with 
durvalumab. The combination will be declared intolerable if ≥ 2 of the 6 patients 
experience a DLT (defined as in Section 6.2) during the first 2 cycles of concurrent 
therapy. The table below summarizes the probability of declaring this combination safe 
for range of true but unknown DLT rates: 
True DLT rate 
10% 
20% 
30% 
40% 
50% 
Probability of <2 DLTs 
among 6 patients 
0.89 
0.66 
0.42 
0.23 
0.11 
Upon completion of the trial, we will summarize the total number of patients enrolled 
on the study, and provide summaries of toxicity rates. We will also review and tabulate 
the DLTs. 
12.1.3 Sample Size Considerations 
The study will proceed to enroll a total of 55 patients if <2 patients among the first 6 
patients enrolled experience a DLT. Depending on the rate of accrual and review of 
the data pertaining to DLT evaluation, accrual may be halted to ensure it is safe to 
continue patient enrollment. 
12.1.4 Monitoring Plan 
While the initial six patients are receiving treatment, the study team will meet via 
teleconference to review and discuss DLTs and the overall trial conduct. 
12.2 
Expansion Phase 
12.2.1 Expansion Study Design and Objectives 
The initial six patients were monitored for safety, without suspension to accrual and, 
the study will proceed with enrollment of a total of 55 patients of whom it is expected 
50 patients will receive treatment (ineligibility rate of 10%). This is a single arm phase 
II study evaluating the benefit of durvalumab in combination with pemetrexed/cisplatin 
(or carboplatin) for the treatment of first-line unresectable pleural mesothelioma. 
Durvalumab will be administered concurrently with Cycle 1-6 of first line pemetrexed 
and cisplatin (or carboplatin) followed by maintenance durvalumab until disease 
progression or a maximum duration of 12 months of durvalumab starting from Cycle 1 
of concurrent treatment. The primary objective of this phase II study is overall survival. 

PrECOG Protocol Number: PrE0505 
Confidential 
Date: 3/19/2018 
 
82 
Secondary objectives include progression-free survival, objective response, immune-
related response, toxicity, and correlatives which will include association of PD-L1 
expression with clinical outcomes. 
12.2.2 Phase II Endpoints 
Overall survival (OS) is defined as the time from randomization to death from any 
cause. Patients that have not had an event reported at analysis will be censored at 
their date of last follow-up. 
Progression-free survival (PFS) is defined as the time from randomization to 
documented disease progression or death from any cause, whichever occurs first. 
Patients who have not experienced an event of interest by the time of analysis will be 
censored at the date they are last known to be alive and progression-free. 
Best objective response will be evaluated via RECIST Version 1.1 criteria modified for 
mesothelioma, as described in the Section 9. 
Immune-related response will be evaluated using the Wolchok criteria [51]. 
Toxicity will be determined using the CTCAE Version 4.03 criteria. 
12.2.3 Phase II Statistical Analysis Plan 
The primary and some secondary analyses will include all eligible patients who started 
assigned therapy including the first six patients evaluated for safety. 
OS and PFS distributions will be estimated using the Kaplan-Meier method, and Cox 
proportional hazards models will be used to estimate the hazard ratios among 
subgroups. The primary test for OS will be based on the Wald test for the log failure 
rate parameter and tested at a one-sided type I error rate of 10%. Any comparisons of 
subgroups will be made using the logrank test and Cox modeling. 
If toxicity rates are compared between subgroups, Fisher’s exact tests with a one-
sided type I error rate of 10% will be used; multivariable logistic regression modeling 
will be used to adjust for the effect of any covariates that are associated with these 
categorical outcomes. 
Point estimates of all endpoints will be accompanied by the corresponding 95% 
confidence intervals. 
In the event that there are missing data, no imputation of the missing data will be 
conducted. We will assume that data are missing at random and will conduct all 
analyses as originally planned because we do not anticipate an excess of missing 
data. 
Subset analyses are planned for known prognostic factors such as performance 
status, age, gender, etc. Subset analyses of all variables, including correlatives, are 
considered to be exploratory in nature. 
12.2.4 Phase II Sample Size Considerations 
The primary comparison will include all eligible patients who started protocol 
treatment, of whom 50 will be accrued. After inflating for an ineligibility rate of 10%, 
the total planned accrual is 55 patients. Based on the randomized phase III trial 
conducted by Vogelzang in this setting [39], we assume that the null hypothesis is that 
the median OS is 12 months with pemetrexed/cisplatin alone (refer to Section 1. for 
additional historical background information). Using a one-sided 0.10 level test, we will 
have 90% power to detect a 37% reduction in the OS hazard rate of 0.058 to 0.037 
(with an accrual period of 24 months for the 50 patients in the primary analysis, and 
an additional 18 months for treatment and follow-up); assuming exponential survival, 
this corresponds to a 58% improvement in the median OS of 12 months to 19 months. 

PrECOG Protocol Number: PrE0505 
Confidential 
Date: 3/19/2018 
 
83 
The number of OS events needed to achieve this power is 32 events. 
12.2.5 Interim Toxicity Assessment 
Because this is the first time that durvalumab is being combined with pemetrexed/ 
cisplatin (or carboplatin) in this setting, close monitoring of toxicity is an important 
endpoint of the trial. We will collect data and conduct an interim safety analysis among 
the first 15 patients who have completed the first two cycles of tri-modal therapy 
without suspension to accrual. The safety analysis will be done based on the eCRF. 
This preliminary toxicity analysis will occur in addition to the twice yearly monitoring 
for toxicity for the purposes of interim reporting. The probability that 5 or more Grade 
4/5 events are observed among the first 15 patients is 0.03 if the true Grade 4/5 non-
hematologic toxicity rate is 12% as expected based on trials of pemetrexed/cisplatin 
in lung cancer and mesothelioma. This probability increases to 0.88 if the true rate of 
Grade 4/5 non-hematologic toxicity is 0.45. Therefore, we will suspend accrual for 
further review of non-hematologic toxicity if we observe at least 5 Grade 4/5 non-
hematologic events among the first 15 patients. 
Interim toxicity assessment was completed on the first 15 patients who completed the 
first two cycles of tri-modal therapy with no safety concerns noted. 
12.2.6 Phase II Projected Accrual 
It is estimated that the total accrual goal of 55 patients will be reached in approximately 
24 months, with a treatment and follow-up period of approximately 18 months, making 
the entire study duration (including safety and efficacy assessments) approximately 
50 months.

Laboratory and Pathology Correlative Studies 
13.1 
Correlative Studies: Mandatory Tumor and Peripheral Blood Samples 
13.1.1 Tumoral Assessments 
Pre-treatment, diagnostic pathology specimens obtained in the course of standard 
biopsy or surgery, FFPE block (preferred) or a minimum of 15 unstained sections of 5 
micron thickness plus 1 H&E slide. Sections should be cut with DNA precautions and 
mounted on plus charged slides. Analyses to be performed may include the following: 
• 
PD-L1 expression (Ventana SP263 assay) 
• 
Whole exome sequencing 
• 
T cell receptor sequencing 
• 
Gene expression by nanostring 
• 
CD8 and other immunologic correlates by IHC 
NOTE: 
Blocks must be less than 3 years old. If unstained slides are being submitted 
they must be less than 90 days old. 
Submitted tumor samples should follow the below guidelines: 
• 
Samples should be collected via a core needle of 18 gauge or larger or be 
collected as an excisional tumour biopsy sample. Where institutional practice in 
this setting uses a smaller gauge needle, samples should be submitted to ensure 
that availability of result can be achieved. 
• 
The tumour specimen submitted should be of sufficient quantity (i.e., >100 tumour 
cells) to allow for PD-L1 immunohistochemistry analyses. 
• 
When archival samples are used to assess PD-L1 status, the age of the sample / 
date of collection should be captured. 
• 
Samples submitted for PD-L1 testing must be formalin fixed and embedded in 
paraffin. 
• 
Samples from fine needle aspirates or bone metastasis are not appropriate for 
PD-L1 analysis. 
13.1.2 Peripheral Blood Assessments 
During Concurrent Therapy 
Research bloods are to be drawn prior to treatment on C1D1, prior to treatment on 
C2D1, and prior to treatment on C5D1 during concurrent therapy or at time of 
confirmed progression IF confirmed progression occurs before Cycle 5, Day 1. 
At each time point, collect one (1) 10 mL EDTA tube and two (2) 10 mL Streck tubes. 
EDTA tube must be collected before the Streck tubes. 
Peripheral blood samples will be obtained for: 
• 
Cytokine profiling (platform to be determined [TBD]) 
• 
ctDNA analysis 
• 
T cell receptor repertoire analysis 
13.1.3 Tumor Tissue and Peripheral Blood Analysis 
Tumor tissue samples and Streck tubes will be sent ambient to John Hopkins 
University and processed EDTA tubes will be sent frozen to the ECOG-ACRIN Central 
Biorepository and Pathology Facility (EA CBPF). 
Testing will be performed following receipt of accrued samples by John Hopkins

University. Any left-over samples will be stored for future analysis. 
13.2 
Assay Methodology 
13.2.1 Tumor Tissue Studies 
Baseline tumor will be obtained in all subjects. Archived tumor biopsies (core needle 
or excision) will be banked for future analysis.  
The following studies may be performed depending on tissue quality and availability. 
Immunohistochemical (IHC) staining. We will perform IHC of tumor samples to assess 
PD-L1 expression in tumor or tumor-infiltrating immune cells using the Ventana SP263 
assay. Markers for further characterization of immune cell subsets (CD3, CD4, CD8, 
CD20, CD68, CD45RO), T regulatory cells-Treg (FOXP3) as well as other immune 
checkpoints (LAG3, TIM3) will be assessed. These additional assessments may be 
performed using multiplex IHC. 
Whole exome sequencing to detect somatic genomic alterations. Using genome-wide 
methods we will perform whole-exome sequencing in pre-treatment tumors for 
identification of genomic correlates of response to durvalumab. Non-synonymous 
missense mutations identified will be used to predict mutant peptides and generate a 
neoantigen signature for each tumor using a computational pipeline we have 
developed. 
T cell receptor sequencing. A separate targeted capture and sequencing analysis of 
the T cell receptor will be performed to assess T cell clonality. 
Gene expression analyses. By nanostring or similar methods may also be performed. 
13.2.2 Peripheral Blood Studies 
Peripheral Blood Mononuclear Cells (PBMCs) will be obtained at time points indicated 
in Section 13.1.2. Samples will be banked for future analysis with plan to evaluate for 
immunologic markers of response and T cell receptor repertoire analysis. 
ctDNA analysis will be performed on Streck tube samples at time points indicated in 
Section 13.1.2. 
13.3 
Pathology Sample Processing and Shipment 
Sites should submit FFPE diagnosis tumor tissue block (preferred) or a minimum of 15 FFPE 
unstained, positively charged slides (2 sections per slide) plus H&E slide from a tumor tissue 
block within 3 months of patient registration. Thickness of the sections should be 5 micron and 
sections should be cut with DNA precautions. 
Blocks must be less than 3 years old. If unstained slides are being submitted they must be less 
than 90 days old.  
A copy of the pathology report from initial diagnosis should be sent when the sample is 
shipped. Samples should be shipped Monday-Thursday. Samples will be shipped ambient 
via overnight courier. 
All samples collected will be labeled with a unique numeric identifier that will be coded for 
patient privacy protection.

Streck tube should be shipped to the lab within 72 hours of collection via overnight 
courier at room temperature (Do NOT freeze. Proper insulation may be required for 
shipment during extreme temperature conditions). NOTE: Samples may be shipped 
on Friday for Monday delivery. 
13.4.2 EDTA Tube Processing for Plasma and Buffy Coat 
**Process sample within 30 minutes of collection** 
• 
Gently mix blood sample by inversion 10 times (do not shake). 
• 
Place tube immediately on wet ice for 5 minutes. 
• 
Centrifuge at 1200 RPM for 15 minutes at 4°C. If a refrigerated centrifuge is not 
available, spin sample at room temperature (1200 RPM for 15 minutes). 
Immediately place the tube on wet ice after centrifugation. 
After centrifugation, the plasma layer will be at the top half of the tube. The nucleated 
cells (WBC) will be in a whitish layer, called the “buffy coat”, just under the plasma and 
above the red blood cells. 
Plasma Preparation: 
• 
Using a transfer pipette take the top two-thirds of the plasma and transfer plasma 
into a 15 ml conical centrifuge tube, be careful not to disturb the buffy coat layer 
in the EDTA tube (NOTE: see below for buffy coat processing instructions). 
Centrifuge the 15 ml conical tube at 1200 RPM for 15 minutes at 4°C. If a 
refrigerated centrifuge is not available, spin sample at room temperature (1200 
RPM for 15 minutes). Immediately place the conical tube on wet ice after 
centrifugation. 
• 
Transfer equal amounts of plasma into two (2) properly labeled polypropylene 
tubes for cryopreservation being careful not to disturb the small PBMC/pellet. 
• 
Store the two aliquots of plasma samples in the freezer at ≤ -70°C or colder until 
they are shipped to the ECOG-ACRIN Central Biorepository and Pathology 
Facility (EA CBPF). 
Buffy Coat Preparation: 
• 
From the EDTA tube remove and aliquot the “buffy coat”; be careful not to disturb 
the layer of red blood cells. 
• 
Store the aliquot of cells in one (1) properly labeled polypropylene tube for 
cryopreservation. 
• 
Store the sample in the freezer at ≤ -70°C or colder until it is shipped to the ECOG-
ACRIN Central Biorepository and Pathology Facility (EA CBPF). 
Plasma and buffy coat samples should be batched together and shipped 
approximately every 4 months. Individual patients should only be included in the 
shipment if all of their samples have been completed. Samples should be shipped 
Monday-Thursday. Samples must be shipped on dry ice via overnight courier. 
Kits will be supplied. Instructions and shipping address will be provided.
