Synopsis
TITLE: 
An Open-Label Study of Rovalpituzumab Tesirine in Subjects with Delta-Like Protein 3-Expressing Advanced 
Solid Tumors
PROTOCOL NUMBER: SCRX001-006
PHASE OF DEVELOPMENT: 1/2
INVESTIGATORS AND STUDY CENTERS: Multicenter
OBJECTIVES:
Primary
!
To assess the safety and tolerability of rovalpituzumab tesirine in subjects with specific delta-like protein 3 
(DLL3)-expressing advanced solid tumors.
Secondary
!
To explore the antitumor activity of rovalpituzumab tesirine in subjects with specific DLL3-expressing 
advanced solid tumors.
!
To study the pharmacokinetics (PK) of and incidence of anti-therapeutic antibodies (ATA) against 
rovalpituzumab tesirine in subjects with specific DLL3-expressing advanced solid tumors.
Exploratory
!
To explore the expression of DLL3 in specific DLL3-expressing advanced solid tumors, and its relationship to 
clinical outcome during treatment with rovalpituzumab tesirine.
!
To explore the effect of rovalpituzumab tesirine on disease biomarkers and pharmacodynamics.
!
To assess change in patient reported outcomes (PRO) within the expansion cohorts (Part B) utilizing the 
European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 
30 (QLQ-C30) questionnaire and EuroQoL Five Dimension Questionnaire (EQ-5D-5L) during treatment with 
rovalpituzumab tesirine.
TEST PRODUCTS, DOSE, AND MODE OF ADMINISTRATION:
!
Rovalpituzumab tesirine 0.2–0.4 mg/kg will be administered intravenously (IV) on Day 1 of each 6-week 
cycle, or according to other dosing regimens recommended by the Safety Monitoring Committee (SMC).
!
Dexamethasone 8 mg will be administered orally (PO) twice daily on Day -1, Day 1 (the day of dosing), and 
Day 2 of each 6-week cycle. 
STUDY DESIGN AND METHODOLOGY:
This is a multicenter, open-label study involving multiple specific advanced solid tumor types. This study consists 
of a Part A dose escalation followed by a Part B expansion. Cancer subtypes will be studied in separate 
disease-specific cohorts in both study parts, A and B. Seven separate cohorts will enroll the following cancer 
types: 
1.
Malignant melanoma 
2.
Medullary thyroid cancer (MTC)
3.
Glioblastoma (GBM)
4.
Large cell neuroendocrine carcinoma (LCNEC) of any origin
5.
Neuroendocrine prostate cancer (NEPC)
6.
High-grade gastroenteropancreatic neuroendocrine carcinoma (GEP NEC)
7.
Other neuroendocrine carcinoma (NEC), and high grade neuroendocrine tumors (NET) 
8.
Solid tumors other than the above
As of protocol version 4.0, cohort 3 (GBM) is closed to enrollment.

Part A Dose Escalation
Rovalpituzumab tesirine will be initially administered on Day 1 of each 6-week cycle, following a standard 
3+3 dose-escalation approach. For each cohort in Part A, dose escalation is planned to proceed until a single 
maximum tolerated dose (MTD) (dose level and dosing interval inclusive) is determined. 
The SMC will monitor the safety of the trial and may make dose-escalation and dosing-interval 
recommendations. The SMC may also recommend further evaluation of the safety at a given dose, investigation 
of alternative dose regimens (including a dose level that is intermediate to the planned dose levels), modification 
of the dosing interval, or limitation to the maximum number of doses. For instance, based on dose-limiting 
toxicities (DLTs) and/or adverse event (AE)-related dose delays, enrollment may change at the same dose to a 
different dosing schedule (e.g., up to 12-week cycles, in which rovalpituzumab tesirine is administered on Day 1 
of each cycle of up to 84 days). The SMC may also recommend the elimination or cancellation of a dose level(s) 
in a cohort based on the experience in other cohorts. For instance, if 3 or more initially-enrolled cohorts establish 
the same dose level as MTD, the remaining cohorts may forgo escalation to higher dose levels.
Response will be assessed by radiographic imaging at protocol-specified time points determined by the subject’s 
dosing schedule. In the 6-week cycle schedule, response assessments will be conducted between Days 36–42 of 
Cycles 1-4, and every 2 cycles thereafter. Prostate cancer-specific assessments are described in Appendix 13.6. 
Part B Expansion Cohorts
To explore the recommended dosing regimen for distinct disease subsets, subjects will be enrolled in 
disease-specific expansion cohorts in Part B. The dose regimen(s) to be examined in the disease-specific cohorts 
will be at the MTD determined in Part A or a lower dose(s) and/or regimen(s), depending on the cumulative data. 
For example, a lower dose regimen may consist of a finite number of doses and/or a mixed-dose regimen, with all 
doses at or below MTD, but varying based on the cycle. The dose(s), regimen(s), and schedule(s) for the 
expansion cohorts will be determined by the Sponsor in consultation with the SMC.
In Part B, up to approximately 174 subjects may be enrolled, including approximately 19 subjects in each of the 
5 disease-specific cohorts and up to 30 subjects each for Cohort 7 and Cohort 8. The goal of the Part B expansion 
is to provide further safety data and preliminary efficacy data for the selected dose regimens.
Response will be assessed by radiographic imaging at protocol-specified time points determined by the subject’s 
dosing schedule. In the 6-week cycle schedule, tumor response will be assessed every 6 weeks during active study 
treatment until 24 weeks, then every 12 weeks, thereafter. Prostate cancer-specific assessments are described in 
Appendix 13.6.
MAJOR ELIGIBILITY CRITERIA:
Subjects with a histologically confirmed, DLL3-expressing advanced solid tumor with measurable disease, that is 
relapsed/refractory to prior standard systemic therapy; ECOG 0–1; adequate hematologic, hepatic and renal 
function; and no prior exposure to a pyrrolobenzodiazepine (PBD)-based drug. Prostate cancer-specific criteria 
are provided in Appendix 13.6.
PLANNED SAMPLE SIZE:
Up to approximately 318 subjects are expected to participate in this two-part trial. Study accrual in Part A is 
approximately 144 subjects (depending on the number of cohorts required to reach the MTD). For Part B, 
approximately 174 subjects may be enrolled. The “Other NEC/NET” and “Other Solid Tumor” cohorts will each 
enroll 30 subjects. The rationale for the sample size is based on the assumption that an objective response rate 
(ORR) of around 15% would be indicative of efficacy worthy of further investigation, given the advanced cancers 
and extensive treatment history in this study population. Conversely, response rates less than 5% would indicate 
lack of efficacy. A sample size of 25 subjects would produce a 90% two-tailed confidence interval (CI) of 5.7% 
to 33.0% around an observed response rate of 16.0%.
STUDY TESTS AND OBSERVATIONS:
Safety assessments include physical examinations, vital signs, body weight, Eastern Cooperative Oncology Group 
(ECOG) score, monitoring of AEs, laboratory tests (hematology, serum chemistries, urinalysis, and coagulation), 
electrocardiograms (ECGs), echocardiograms (ECHOs), fluid retention questionnaire, and monitoring of 
concomitant medications.
Efficacy assessments will consist of radiographic imaging. Responses will be categorized by Response Evaluation

Criteria in Solid Tumors (RECIST v1.1) (Eisenhauer 2009). Prostate cancer subjects will also be categorized by 
Prostate Cancer Clinical Trials Working Group 3 (PCWG3) criteria (Scher 2016), including the use of bone 
scintigraphy and prostate-specific antigen (PSA) testing, as described in Appendix 13.6.
PK assessments will include blood samples for rovalpituzumab tesirine and anti-therapeutic antibodies (ATAs).
Pharmacodynamic and biomarker assessments will include analyses of tumor tissue for DLL3 expression, and 
blood samples for tumor markers, circulating tumor cells, and soluble biomarkers, such as soluble DLL3.
Changes from baseline in PROs, utilizing the EORTC QLQ-C30 and EQ-5D-5L, will be assessed.
STATISTICAL METHODS:
As a general strategy, data will be analyzed by disease, cohort, and dose regimen. 
Safety analysis will include summaries by disease, by cohort, and/or by dose level of: AEs, laboratory measures, 
physical examinations, ECGs, and vital signs using data from subjects in the Safety Analysis set. The incidence of 
DLTs will be summarized using data from the DLT-Evaluable Set (defined as all subjects who receive any 
amount of study drug and either experienced a DLT, or were followed for the full DLT evaluation period).
The ORR will be reported with category counts, percentage, and 90% two-tailed CI. Duration of response (DOR), 
progression-free survival (PFS), and overall survival (OS) will be evaluated using Kaplan-Meier estimates, and 
curves will be generated based on these estimates.

Introduction 
1.1
Delta-like Protein 3
Delta-like protein 3 (DLL3) is an inhibitory ligand of the Notch receptor family. It is highly 
expressed in high-grade tumors of neuroendocrine origin such as small cell lung cancer (SCLC), 
including its tumor perpetuating cells (TPCs), but with no detectable expression in normal tissues 
or non-neuroendocrine tumor types (Saunders 2015; Stemcentrx data on file). While the function 
of DLL3 has not been clearly defined, it has been implicated in the regulation of cell 
development and fate decisions (Chapman 2011; Dunwoodie 1997).
1.2
Rovalpituzumab Tesirine
Rovalpituzumab tesirine (SC16LD6.5) is a DLL3-targeted antibody-drug conjugate (ADC) 
consisting of the humanized DLL3-specific IgG1 monoclonal antibody SC16; the 
deoxyribonucleic acid (DNA) cross-linking agent SC-DR002 (D6.5); and a protease-cleavable 
linker that covalently links SC-DR002 to SC16. The primary mechanism of rovalpituzumab 
tesirine is binding of the ADC to DLL3 on target-expressing cells, followed by internalization of 
the ADC-DLL3 complex and release of SC-DR002 via proteolytic cleavage in late endosomes. 
Interstrand crosslinks of cellular DNA induced by intercalated SC-DR002 leads to cellular 
cytotoxicity. ADCs like rovalpituzumab tesirine represent a potential advantage over traditional 
chemotherapy by delivering cytotoxic agents to specific target cells, resulting in an improved 
safety profile.
In a Phase 1 study (Study SCRX16-001), rovalpituzumab tesirine dosed at 0.2 – 0.4 mg/kg 
exhibited encouraging efficacy in recurrent SCLC, achieving a 31% (8/26) and 85% (22/26) 
central review-adjudicated confirmed objective response rate (ORR) and clinical benefit rate 
(CBR), respectively, in subjects whose tumors expressed DLL3 in ≥50% of cells.  Median 
overall survival was 7.7 months in DLL3 ≥ 50% subjects at all dose levels, with a 1-year survival 
rate of 30%. The most frequent grade 3 or worse treatment-related adverse events in 74 patients 
with small-cell lung cancer were thrombocytopenia (11%), pleural effusion (8%), and increased 
lipase (7%). Drug-related serious adverse events occurred in 28 (38%) of 74 patients. The 
recommended phase 2 dose and schedule is 0·3 mg/kg every 6 weeks (AbbVie Stemcentrx, data 
on file).
In a Phase 2 SCRX001-002 (TRINITY) study in patients with SCLC recurrent after at least two 
systemic chemotherapy regimens, rovalpituzumab tesirine dosed at 0.3 mg/kg every 6 weeks for 
two cycles (with an option for additional two cycles upon progression occurring ≥ 12 weeks after 
the second dose) had shown confirmed objective response rate of 16%, progression-free survival 
of 3.9 months and overall survival of 5.6 months in 3rd line DLL3High patients.  Of note, 
prolonged stable disease with target lesion size reduction has been observed in a considerable 
number of patients receiving additional post-progression cycles of rovalpituzumab tesirine. Drug 
related grade 3 or above treatment emergent adverse events that occurred in at least 10 subjects 
include thrombocytopenia (11%), photosensitivity reactions (7%), anemia (4%), fatigue (4%),

and pleural effusion (4%). Adverse events leading to study treatment discontinuation occurred 
in7% of subjects   (AbbVie Stemcentrx, data on file).
1.3
DLL3-Expressing Cancers Other than Small Cell Lung Cancer
Several other cancers of neuroendocrine origin appear to express DLL3 in a significant 
proportion, including melanoma (~25%), medullary thyroid carcinoma (MTC; >50%), 
glioblastoma (GBM, ~70%), and neuroendocrine cancers, including large-cell neuroendocrine 
carcinoma (LCNEC, ~80%), neuroendocrine prostate cancer (NEPC, ~10%), and high-grade 
gastroenteropancreatic neuroendocrine carcinoma (GEP NEC, ~20%) (Saunders 2015;
Stemcentrx data on file). Novel therapeutic approaches continue to be needed for each of these 
cancers, as described below.
1.3.1
Metastatic Melanoma
Although most cases of cutaneous melanoma are diagnosed at an early stage when surgical 
excision can be curative, some patients have metastatic disease at presentation (2–5%), and/or 
develop metastases after initial definitive treatment. Primary treatment for metastatic melanoma 
currently involves immunotherapy, consisting of programmed death receptor-1 (PD-1) inhibitors 
(e.g., nivolumab, pembrolizumab), typically in combination with a cytotoxic T-lymphocyte 
antigen 4 (CTLA4) inhibitor (e.g., ipilimumab), and/or kinase inhibitors (e.g., BRAF inhibition 
with vemurafenib or dabrafenib, MEK inhibition with trametinib, or KIT inhibition with 
imatinib) in patients with corresponding driver mutations (e.g., in BRAF or KIT). Nonetheless, 
recurrence remains virtually inevitable despite these therapies, with median durations of response 
(DORs) of only 5–6 months and progression-free survival (PFS) generally less than 1 year 
(National Comprehensive Cancer Network, NCCN Melanoma 2016; Dummer 2015).
1.3.2
Medullary Thyroid Carcinoma
Medullary thyroid carcinoma (MTC) accounts for approximately 1–2% of thyroid cancers. 
MTC is characterized by the production of calcitonin, and is often associated with mutations in 
the RET proto-oncogene, either sporadically or as a component of the type 2 multiple endocrine 
neoplasia (MEN) syndromes, MEN2A and MEN2B, and the related syndrome, familial MTC 
(FMTC). Most localized MTC responds to locoregional therapies, including surgery and/or 
radiation therapy, but metastatic disease is present in 10–15% of patients at the time of diagnosis, 
and may develop after failure of definitive therapy. Frontline systemic therapy in this setting 
typically involves a tyrosine kinase inhibitor (TKI) such as vandetanib or cabozantinib, where 
clinical benefit (partial response [PR] or stable disease [SD]) in 50–60% of subjects has been 
observed. However, benefit duration is generally limited to about 12–24 months, with toxicities 
often requiring drug withdrawal or dose reduction (NCCN Thyroid 2015; Wells 2015).

1.3.3
Glioblastoma
Glioblastoma (GBM), the most common primary malignant adult brain tumor, accounts for about 
54% of all gliomas, and may arise de novo (primary GBM), usually in older patients, or evolve 
from a low-grade glioma (secondary GBM). Initial treatment typically includes a combination of 
surgery and radiation therapy, including adjunct local nitrosourea chemotherapy (carmustine). 
The alkylating agent temozolomide has emerged as the standard of care, in conjunction with 
postoperative radiation therapy for younger patients with good performance status. Nonetheless, 
the prognosis for GBM remains poor and it remains the most lethal brain tumor: nearly all GBMs 
recur, with only one-third of patients surviving for 1 year and less than 5% beyond 5 years. 
(NCCN CNS 2015; Stupp 2014).
1.3.4
Neuroendocrine Carcinomas 
The neuroendocrine tumors (NETs) comprise a rare, but broad family, often sporadic, but 
sometimes arising in the context of inherited genetic syndromes, such as MEN types 1 and 2. 
Poorly-differentiated tumors are high grade neuroendocrine carcinomas (NECs) with clinical 
behavior distinct from well-differentiated NETs, and may occur in a wide variety of organs, 
including lung, intestine and pancreas, and prostate. Early-stage cancers may sometimes be 
amenable to surgical resection and chemotherapy, with or without radiotherapy. Otherwise, 
radiotherapy in combination with chemotherapy or chemotherapy alone is generally considered 
for unresectable locoregional or metastatic disease, respectively — typically following SCLC 
guidelines. SCLC regimens, such as cisplatin or carboplatin in combination with etoposide, are 
commonly used for primary chemotherapy, although somatostatin analogues are sometimes 
considered for symptom control in hormone-secreting or scintigraphy-positive cases 
(NCCN NEC 2015; Oberg 2012; Oberg, Knigge 2012). Nonetheless, prognosis remains poor, 
with most series describing overall survival (OS) less than 18 months (e.g., Hainsworth 2006; 
Sorbye 2013; Yamaguchi 2014).
1.4
Rationale for the Study and Anticipated Risks
Rovalpituzumab tesirine may be effective in multiple cancers that express DLL3. This study will 
explore further the safety, tolerability, and potential therapeutic utility of rovalpituzumab tesirine 
in subjects with such non-SCLC DLL3+ tumors, with the intent to provide the basis for further 
development of rovalpituzumab tesirine in one or more of these evaluated indications. 
As of 30 June 2016, 104 subjects (SCLC or LCNEC) had received at least one dose of 
rovalpituzumab tesirine at doses ranging from 0.05 mg/kg to 0.8 mg/kg on an every 3 weeks 
(Q3wk) schedule (34 subjects) and 0.3 mg/kg to 0.4 mg/kg on an every 6 weeks (Q6wk) 
schedule (70 subjects).

The most frequently reported treatment-emergent adverse event (TEAE) terms in all treated 
subjects were fatigue (49%), pleural effusion (34%), and dyspnea (31%); the most frequently 
reported TEAE terms considered related to rovalpituzumab tesirine by the Investigator were 
fatigue (35%), pleural effusion (28%), and peripheral edema (26%). 
The most frequently reported Grade 3/4 TEAEs were dyspnea (14%), pleural effusion (12%), 
and fatigue (11%); the most frequently reported Grade 3/4 TEAEs considered related to 
rovalpituzumab tesirine were pleural effusion and thrombocytopenia (10% each), and fatigue and 
increased lipase (6% each). 
Serious adverse events (SAEs) were reported in 49 subjects (47%), 26 (25%) were considered 
related to rovalpituzumab tesirine by the Investigator. The most common SAE was pleural 
effusion, occurring in 18 subjects (17%); all occurrences were considered related to 
rovalpituzumab tesirine. The second most common related SAE was pericardial effusion, in 
8 subjects (8%). Six subjects experienced a fatal AE, 2 of which were considered related to 
rovalpituzumab tesirine (acute kidney injury and tumor hemorrhage). 
Preclinical toxicology studies conducted in the rat and the cynomolgus monkey have identified 
the bone marrow, lung, and kidney as a potential source of clinical adverse events (AEs) (refer to 
Section 4.3.1 of the current Rovalpituzumab Tesirine Investigator’s Brochure [IB]; Stemcentrx 
data on file). Accordingly, safety assessments will include regular assessments at protocol-
specified time points of routine physical examination, laboratory and imaging tests, as well as 
echocardiograms (ECHOs), a fluid retention questionnaire, daily weights, and untimed (spot) 
analysis of protein.

Investigational Plan
3.1
Summary of Study Design
This is a multicenter, open-label study of rovalpituzumab tesirine in subjects with 
DLL3-expressing advanced solid tumors. The study will include 7 cohorts of subjects with the 
following cancers:
1. Malignant melanoma
2. Medullary thyroid cancer (MTC)
3. Glioblastoma 
4. Large cell neuroendocrine carcinoma (LCNEC) of any origin
5. Neuroendocrine prostate cancer (NEPC)
6. High-grade gastroenteropancreatic neuroendocrine carcinoma (GEP NEC)
7. Other neuroendocrine carcinoma (NEC) and high grade neuroendocrine tumors (NET)
8. Solid tumors other than the above
As of protocol version 4.0, cohort 3 (Glioblastoma) is closed to enrollment. Specific guidance for 
cohort 3 (Glioblastoma) subjects (protocol version 3.0) are provided in Appendix 13.3.
Each disease-specific cohort will include two parts:
!
Part A – Dose-Regimen Finding: Will involve disease-specific dose escalation, and possible 
dose-interval modification, to define the maximum tolerated dose (MTD) and/or possible 
recommended Phase 2 dose(s) (RP2Ds).
!
Part B – Expansion Cohorts: Disease-specific expansion cohorts may be enrolled. Subjects in 
the expansion cohorts will be treated with a dose regimen(s) at or below the MTD and/or 
RP2D determined in Part A.
Dose limiting toxicities (DLTs) will be assessed during the DLT Evaluation Period 
(Section 3.1.3) for subjects in Part A, the dose regimen finding portion of the trial. 
Safety will be monitored throughout the trial by the Safety Monitoring Committee (SMC) 
consisting at least of a Medical Monitor, Investigators, and the study biostatistician. The SMC
will meet routinely to review the emerging safety, select pharmacodynamic and efficacy data, 
and may make dose-escalation and dosing-interval recommendations. The SMC may recommend 
further evaluation of safety at a given dose level, investigation of alternative dose regimens, 
including a dose level that is intermediate to the planned dose levels, modification of the dosing 
interval, limitation to the maximum number of doses, and/or elimination or cancellation of a dose 
level(s) in a cohort based on the experience in other cohorts. The SMC will also review 
cumulative safety data in order to identify safety concerns that may emerge due to cumulative 
exposure beyond the DLT window. The process for dose-escalation decisions and dose-interval 
recommendations, and the roles and responsibilities of the SMC may be detailed separately.

Tumor response will be assessed every 6 weeks during active study treatment until 24 weeks, 
and then every 12 weeks thereafter. Treatment decisions by the Investigator will be based on
RECIST v1.1 (and/or PCWG3 for prostate cancer; Appendix 13.7).
Subjects will be eligible to continue treatment until unacceptable toxicity, disease progression 
(PD), withdrawal of consent, study termination, or completion of a planned course of treatment 
(if a regimen with a limited number of doses is selected), whichever occurs first. Subjects who 
discontinue study treatment prior to PD will be evaluated for response every 6 weeks until 
24 weeks, then every 12 weeks until PD or initiation of new anticancer treatment, whichever 
occurs first, and will afterwards be followed for survival until death or study termination, 
whichever occurs first. Appendix 13.7 includes specific additional guidance for prostate cancer 
subjects.
Blood samples for PK, immunogenicity, biomarker and pharmacodynamics assessments will be 
collected at protocol-defined time points to support the study endpoints (Sections 7.4 and 7.5).
3.1.1
Part A Dose-Regimen Finding
For Part A, the planned dose levels of rovalpituzumab tesirine are presented in Table 3-1. 
Initially, rovalpituzumab tesirine will be administered according to the Schedule Q6wk, on 
Day 1 of each 6-week cycle, continuous dosing. If the MTD is determined to be 0.3 mg/kg in the 
initial 3 dose levels, further dose escalation will be stopped.

Dose-Escalation Decision Summary
During 3+3 dose escalation, DLTs will be assessed during the DLT Evaluation Period 
(Section 3.1.3). If 0 of 3 subjects experience a DLT in a cohort, the next dose level will be 
opened for enrollment. If ≥2 of 3 subjects in a cohort experience a DLT, the MTD will have been 
exceeded and dose escalation will stop. If 1 of 3 subjects in a cohort experiences a DLT, an 
additional 3 subjects will be treated at that same dose level for a total of 6 subjects. If none of the 
3 additional subjects experiences a DLT (1 of 6 subjects with a DLT), dose escalation will 
continue to the next higher dose level. If 1 or more of the 3 additional subjects experiences a 
DLT (≥2 of 6 subjects with a DLT), the MTD will have been exceeded and dose escalation will 
not continue. Subjects who do not complete the DLT-evaluation period due to non-DLT reasons 
will not be considered DLT-evaluable and will be replaced for the DLT evaluation.
The MTD and RP2D will be determined by the Sponsor in consultation with the SMC after a 
review of all available data. At least 6 subjects must be treated at the putative MTD or RP2D, 
with no more than 1 incident of DLT.
If 3 or more disease-specific cohorts clear the 0.3 mg/kg or 0.4 mg/kg dose level and the Q6wk 
schedule, then the SMC may evaluate all the data available to determine an appropriate RP2D 
and the Part B expansion may proceed for all the cohorts in the study at these dose(s) and 
schedule.
During dose escalation, additional subjects may be enrolled at a dose level previously declared to 
be tolerated in order to explore further the safety and tolerability of the regimen. For instance, if

all 3 or 6 subjects necessary for DLT evaluation have been enrolled in a cohort, but have not yet 
completed the DLT evaluation period, additional subjects may be enrolled at a lower dose 
level(s), with approval of the Medical Monitor and Sponsor.
3.1.2
Part B Expansion Cohorts 
To explore the recommended dosing regimen for distinct disease subsets, subjects will be 
enrolled in disease-specific expansion cohorts in Part B. The dose regimen(s) to be examined in 
the disease-specific cohorts will be the MTD determined in Part A or a lower dose(s) and/or 
regimen(s), depending on the cumulative data. For example, a lower dose regimen may consist 
of a finite number of doses and/or a mixed-dose regimen, with all doses at or below MTD, but 
varying based on the cycle. The dose(s), regimen(s) and schedule(s) for each expansion cohort 
will be determined by the Sponsor in consultation with the SMC. For Part B, approximately 
174 subjects may be enrolled. The “Other NEC/NET” and “Other Solid Tumor” cohorts will 
each enroll 30 subjects. Additional information regarding sample size is provided in 
Section 10.1, Determination of Sample Size.
3.1.3
Definition of Dose-Limiting Toxicities 
The DLT evaluation period is the first 3 weeks of the first cycle of treatment for all subjects in 
Part A. DLTs are defined as any of the following in the DLT evaluation period, graded according 
to the National Cancer Institute’s Common Terminology Criteria for Adverse Events (NCI 
CTCAE), version 4.03:
!
Grade 4 thrombocytopenia (or Grade 3 thrombocytopenia with bleeding) lasting more than 
7 days and/or requiring platelet transfusion
!
Grade 4 neutropenia lasting more than 7 days, and/or requiring hematopoietic growth factor 
rescue, or any febrile neutropenia (Grade 3 or 4 neutropenia with concurrent fever ≥38.3°C) 
!
Grade 4 anemia unrelated to underlying disease
!
Clinically-significant Grade 3 or 4 non-hematologic laboratory abnormality that does not 
resolve to Grade 0/1 or baseline within 7 days
!
Grade 3 or 4 non-laboratory AE with the exception of fatigue, asthenia, nausea, or other 
manageable constitutional symptom
The following events will not be considered DLTs:
!
Any AE ≥ Grade 3 clearly determined to be unrelated to study drug (e.g., PD)
!
≥Grade 3 isolated alkaline phosphatase, amylase or lipase laboratory abnormality of any 
duration

rovalpituzumab tesirine as administered in accordance with this protocol, and then experience 
PD at least 12 weeks after the most recent dose of rovalpituzumab tesirine. The retreatment dose 
level and regimen for each subject will be determined by the Medical Monitor, Sponsor or

3.2
Discussion and Rationale for Study Design
3.2.1
Study Design
This is the first clinical study with rovalpituzumab tesirine that will have cohorts dedicated to 
specific tumor types other than SCLC. Since the safety and tolerability of rovalpituzumab 
tesirine in tumor types other than SCLC has not been well-studied, separate dose escalations are 
planned for each cohort. In addition, some NEC cancer types warrant specific considerations in 
trial design, such as the utility of bone scintigraphy and PSA in prostate cancer (Kulke 2011; 
Scher 2016), and the safety and tolerability of rovalpituzumab tesirine may differ in cancers of 
different primary organs (Stemcentrx data on file). Therefore, some specific NECs will be 
enrolled and analyzed in distinct cohorts in this study, including LCNEC, NEPC, and high-grade 
GEP NEC (Section 3.1; Appendix 13.7).
Each Part A dose escalation will utilize a traditional rule-based design, including 3+3 cohorts at 
anticipated active doses to evaluate the safety and tolerability of multiple dose levels in a 
disease-specific fashion (Le Tourneau 2009), and will allow definition of the MTD, if one can be 
identified. In Part B, potential therapeutic doses (i.e., the MTD and/or lower doses as guided by 
the cumulative clinical experience in Part A) may be studied in expansion cohorts of subjects 
with specific solid tumor types. 
Evaluation of the study endpoints will inform the safety profile of rovalpituzumab tesirine in 
advanced solid tumors and may provide evidence of antitumor activity that could influence the 
trial design of subsequent studies.
3.2.2
Method of Assigning Subjects to Treatment Groups
Upon approval of subject registration, the Sponsor or designee will assign each subject to a 
disease-specific cohort. The cohort assignment decisions will be documented in the clinical trial 
master file.
3.2.3
Rationale for Selection of Doses
In a Phase 1 study with rovalpituzumab tesirine, the MTD was established at 0.4 mg/kg Q3wk 
based on the incidence of Cycle 1 toxicities, while the RP2D in SCLC was chosen as 0.3 mg/kg 
Q6wk based on the toxicity and efficacy profile during multiple cycle dosing (Stemcentrx data 
on file). For this study, dosing will begin with 0.2 mg/kg Q6wk, a dose level -1 relative to the

5.2.4.1
Dose Holds or Delays
Subjects who experience DLT in Cycle 1 should not receive further treatment with study drug 
unless clinical benefit is demonstrated with adequately managed toxicity and there is approval 
from the Medical Monitor and/or Sponsor. The subsequent dose level will be defined by the 
Medical Monitor and/or Sponsor in discussion with the site Investigator in the context of the type 
of AE observed.
If a subject has a clinically significant, unresolved AE on Day 1 of Cycle 2 or beyond, the start 
of the cycle may be delayed for up to 12 weeks. Longer dose delays may be permitted with the 
approval of the Medical Monitor if there was no documented PD. The AE must resolve to 
baseline or ≤Grade 1 prior to proceeding with treatment, unless the AE is determined to be 
clearly unrelated to study drug, or toxicity has been adequately managed.
Serosal effusions (e.g., pleural, pericardial, or ascites) that have been drained should remain 
stable or improved for at least 2 weeks prior to resumption of dosing (refer to Table 5-1, below).
5.2.4.2
Clinical Monitoring of Grade 3 or Grade 4 Adverse Events 
Subjects who experience Grade 3 or 4 non-laboratory AEs will require weekly or more frequent 
clinical assessments, as appropriate. The assessments should include review of AEs, concomitant 
medications, vital signs, weight, physical examination, ECOG performance status, laboratory 
and other testing, as clinically appropriate.
Subjects who experience Grade 3 or 4 hematologic AEs should have repeat complete blood 
count (CBC) assessment at least every 3 days or more frequently, as clinically appropriate, until 
resolution of hematologic toxicity to Grade 2 or lower.
Subjects who experience Grade 3 or 4 non-hematologic laboratory AEs will require more 
frequent laboratory assessments, as clinically appropriate, until resolution of the AEs.
Subjects who experience Grade 3 or 4 laboratory abnormalities may require more frequent 
laboratory assessments, as clinically appropriate.
5.2.4.3
Dose Reductions Due to Adverse Events
Subjects who experience a Grade 3 or 4 AE (unless the AE is determined to be clearly unrelated 
to study drug) should have a dose reduction in subsequent treatment cycles to dose level -1 or -2, 
or as suggested following discussion with the Medical Monitor and/or Sponsor. If the Grade 3 or 
4 AE recurs after dose reduction, study treatment must be permanently discontinued. Table 5-1
displays specific toxicities requiring dose reduction and/or discontinuation. Adjustments to these 
guidelines may occur based on the clinical judgment of the Investigator and with approval of the 
Medical Monitor.

Required Premedication and Postmedication
All subjects enrolled will receive premedication consisting of dexamethasone orally (PO) at 
8 mg twice daily given on Day –1, Day 1 (the day of dosing), and Day 2 of each cycle. 
Dexamethasone will be provided through a subject’s local prescription by Investigator or other 
provider (i.e., dexamethasone will not be provided by the Sponsor). When dexamethasone is not 
available, the glucocorticoid-equivalent dose of an alternate corticosteroid may be administered. 
Parenteral (e.g., IV) administration may be substituted for PO at the discretion of the 
Investigator.
5.4
Concomitant Therapy
All concomitant medications, blood products, procedures and radiotherapy administered will 
be recorded from Day 1 (predose) through the safety reporting period (Section 7.2 and 
Appendix 13.1). Any concomitant therapy given for a study protocol-related AE should be 
recorded from the time of informed consent.
5.4.1
Required Concomitant Therapy
Other than dexamethasone (Section 5.3), there are no required concomitant therapies. However, 
due to the potential for rovalpituzumab tesirine-related skin photosensitivity, subjects should be 
advised to avoid unprotected sun exposure and use a broad spectrum sunscreen (sun protection 
factor [SPF] of at least 30), protective clothing, a broad-brimmed hat, and sunglasses when 
outdoors or when driving or riding in the car for more than 1 hour, with re-application of 
sunscreen as activity-appropriate.
5.4.2
Allowed Concomitant Therapy
Standard supportive care for drug-related toxicity is permitted, including growth factors and 
blood product transfusions in accordance with local institutional standards. Other standard 
supportive care for symptom control or drug-related toxicity is allowed, such as analgesics, 
anti-emetics, electrolyte replacement, and hydration. Bone modifying agents for bone metastases 
are also permitted in accordance with local institutional standards. Other prescribed medications 
for non-neoplastic conditions are allowed, as well as vitamins and nutritional supplements.

Further ongoing treatments may be permitted for prostate cancer subjects according to 
Appendix 13.7.
Concomitant prednisone (or equivalent) may be used at a dose of ≤20 mg/day. The use of 
intermittent high-dose corticosteroid treatment to prevent or manage hypersensitivity reactions, 
serosal effusions (refer to Section 5.5.1), or other non-cancer-related symptoms, including 
premedication for known hypersensitivity reactions to contrast for scans is allowed.
Routine prophylaxis with vaccines is permitted; however, vaccines used should not contain live 
micro-organisms.
If the subject is taking chronic suppressive anti-infectives (antiviral, antifungal, or antibacterial), 
appropriate investigation must be completed prior to registration and documentation must 
exclude active infection. The subject should continue suppressive anti-infectives for the duration 
of study participation.
Palliative radiation therapy is permitted. Study drug must be held during therapy. If more than 
6 weeks have elapsed since the previous dose of study drug, the subject should undergo a 
radiographic tumor assessment before restarting study drug. If PD is detected in new sites, the 
subject will be required to discontinue study treatment (but may be eligible for re-treatment 
according to Section 3.1.4).
5.4.2.1
Treatment of Isolated Central Nervous System Progression
In the event of isolated CNS progression during study treatment, study drug may be withheld 
while palliative treatment is administered, e.g., a standard course of whole brain radiotherapy or 
stereotactic radiosurgery (SRS) in accordance with institutional practice, and restarted within 
1 week after completion of radiotherapy. During this time the subject should be fully evaluated 
for other sites of progression. If more than 6 weeks have elapsed since the previous dose of study 
drug, the subject should undergo a radiographic tumor assessment before restarting study drug. If 
additional sites of PD are present, the subject will be required to discontinue study treatment (but 
may be eligible for re-treatment according to Section 3.1.4).
5.4.3
Prohibited Concomitant Therapy
Subjects may not receive other investigational drugs, immunosuppressive medications, or 
systemic anti-neoplastic therapy during the study, other than as allowed in Sections 4, 5.2.4, 
and 5.4.2, and Appendix 13.7.

Management of Adverse Reactions
5.5.1
Serosal Effusions
Serosal effusions (pleural or pericardial, or ascites) have been observed with rovalpituzumab 
tesirine, and have the potential to be life-threatening (e.g., pericardial tamponade). Therefore,

development of any of these events, or worsening from baseline, warrants prompt evaluation by 
the Investigator or designee. Cytology analysis should be done for pleural and pericardial 
effusion as appropriate. Alternative causes, such as infection, congestive heart failure, or PD, 
should be ruled out. When appropriate, a unifying diagnosis or reached diagnosis should be 
reported (e.g., “heart failure,” not simply “pleural effusion” and “edema limbs”). When 
considered clinically significant (e.g., Grade 2 or higher and considered related to study drug):
!
Systemic corticosteroids, when initiated promptly, have been reported to be beneficial in 
some prior cases. The Investigator should consider a tapering regimen, such as 
dexamethasone up to 8 mg orally twice a day for 5 days, followed by 4 mg orally twice 
a day for 5 days, then 2 mg orally twice a day for 5 days. Alternatively, nonsteroidal 
therapies for serositis may be considered, such as non-steroidal anti-inflammatory drugs 
(NSAIDs, e.g., ibuprofen 400–600 mg orally 3 to 4 times daily) or colchicine (e.g., 
0.6 mg orally 2 to 3 times daily) given for 1–2 weeks.
!
Until clinical experience suggests otherwise, guidance for dose delay and/or reduction, 
as well as criteria for ongoing dosing, should follow Section 5.2.4.
5.5.2
Skin Reactions
Recommendations for management of photosensitivity reactions are outlined below in Table 5-2.
Photosensitivity was reported in patients treated with Rova-T including severe events.  
Photosensitivity reactions may occur hours to days after sun exposure. The median time to onset 
was 30 days (range 1 to 247 days). Patients should be advised to avoid direct and indirect sun 
exposure as much as possible during Rova-T treatment and for 30 days after the last dose. If 
unavoidable, patients should wear protective clothing and sunglasses, and use a broad-spectrum 
sunscreen and lip balm (SPF 30 or greater). 31 – 90 days after last dose, the patient may resume 
outdoor activities with appropriate sun protection including broad brimmed hat, protective 
clothing and sunscreen SPF 30 or higher. Skin reactions should be evaluated promptly and 
treated with topical or systemic steroids as indicated (refer to Table 5-2). Rova-T dose should be 
delayed, reduced or discontinued as necessary (refer to Table 5-1)
All cutaneous reactions which develop during treatment warrant prompt evaluation. Skin toxicity 
with rovalpituzumab tesirine may consist of photosensitivity but possibly other reactions such as 
palmar-plantar erythrodysesthesia or erythema multiforme. As such, development of a cutaneous 
reaction during treatment warrants prompt evaluation by the Investigator or designee:
!
If clinically consistent with photosensitivity, the AE should be reported as such (using 
medically accurate and descriptive AE terminology), and managed as described below in 
Table 5-2.

!
For clinically more severe cases of photosensitivity or if clinically not consistent with 
photosensitivity, photodocumentation to facilitate later review by the Sponsor or designee 
may occur.
o
Formal evaluation by a dermatologist, including possible skin biopsy to rule out 
alternative etiologies, such as erythema multiforme which may warrant 
discontinuation of study drug, and to facilitate the most appropriate terminology for 
AE reporting, is recommended.
o
Photodocumentation of skin toxicity, if available, may be requested by the TAMD. 
The investigative site will take measures to protect the identity of the patient. These 
measures include taking the photograph very close to the affected skin region to 
exclude facial features, or if facial features cannot be excluded due to the location of 
the skin reaction, covering identifying features (such as the eyes) with a black 
rectangle.
All events of cutaneous toxicity should be monitored until resolution or return to baseline.

Potential Drug-Induced Liver Injury
Wherever possible, timely confirmation of initial liver-related laboratory abnormalities should 
occur prior to the reporting of a potential drug-induced liver injury (DILI) event. All occurrences 
of potential DILIs, meeting the defined criteria, must be reported as SAEs.

Potential drug-induced liver injury is defined as:
!
ALT or AST elevation >3× ULN; and
!
Concurrent total bilirubin >2× ULN, without initial findings of cholestasis (elevated 
serum alkaline phosphatase), and
!
No other immediately apparent possible causes of aminotransferase (AT) elevation and 
hyperbilirubinemia, including, but not limited to, viral hepatitis, pre-existing chronic or 
acute liver disease or tumor(s), or the administration of other drug(s) known to be 
hepatotoxic
In general, an increase of AT to >3× ULN should be followed by repeat testing within 48–
72 hours of all four of the usual measures (ALT, AST, alkaline phosphatase, total bilirubin) to 
confirm the abnormalities and to determine if they are increasing or decreasing. Inquiry 
regarding symptoms should also be made (e.g., fatigue, nausea, vomiting, right upper quadrant 
pain or tenderness, fever, rash). Subjects may be retested locally, but normal laboratory ranges 
should be recorded and results made to the Investigator immediately. All data must be recorded 
in the CRF. If symptoms persist or repeat testing shows AT >3× ULN for subjects with normal 
baseline measures or 2-fold increases above baseline values for subjects with elevated values 
before drug exposure, close observation should be initiated. If close monitoring is not possible, 
study drug should be discontinued.
Close observation includes:
!
Repeating liver enzyme and serum bilirubin tests 2 or 3 times weekly. Frequency of 
retesting can decrease to once a week or less if abnormalities stabilize or the trial drug 
has been discontinued and the subject is asymptomatic.
!
Obtaining a more detailed history of symptoms and prior or concurrent diseases
!
Obtaining a history of concomitant drug use (including nonprescription medications and 
herbal and dietary supplement preparations), alcohol use, recreational drug use, and 
special diets
!
Ruling out acute viral hepatitis types A, B, C, D, and E; autoimmune or alcoholic 
hepatitis; non-alcoholic steatohepatitis (NASH); hypoxic/ischemic hepatopathy; and 
biliary tract disease
!
Obtaining a history of exposure to environmental chemical agents
!
Obtaining additional tests to evaluate liver function, as appropriate (e.g., international 
normalized ratio [INR], direct bilirubin)
!
Considering gastroenterology or hepatology consultations
Discontinuation of study drug should be considered if potential DILI is suspected and:
!
ALT or AST >8× ULN
!
ALT or AST >5× ULN for more than 2 weeks

!
ALT or AST >3× ULN with the appearance of fatigue, nausea, vomiting, right upper 
quadrant pain or tenderness, fever, rash, and/or eosinophilia
All subjects showing possible DILI should be followed until all abnormalities return to normal or 
to the baseline state.
5.5.4
Monitoring and Management of Edema
!
The majority of the edema events with rovalpituzumab tesirine have been reported as low 
grade 1 or 2 (mild or moderate); however, a small number of fatal events of generalized 
edema have been reported with rovalpituzumab tesirine.  Physical exams and monitoring 
of weight gain and signs or symptoms of fluid retention should be conducted during 
treatment.
!
Consistent with institutional guidelines or standard practice, the use of diuretics with or 
without albumin may be considered in subjects with clinically significant edema and 
hypoalbuminemia.  The selection and use of diuretics in subjects should be based on 
individual clinical characteristics and include monitoring of electrolyte status and signs or 
symptoms of intravascular volume depletion such as hypotension and impaired renal 
function.
!
Systemic corticosteroids, when initiated promptly, have been reported to be beneficial in 
some prior cases.
5.5.5
Monitoring and Management of Pneumonitis:
!
Pneumonitis has been infrequently reported with rovalpituzumab tesirine but has resulted 
in fatal outcomes. Although the causal role of rovalpituzumab tesirine could not be ruled 
out, the reports of pneumonitis had one or more confounders including underlying 
pulmonary disease/cancer, prior thoracic radiation, prior cytotoxic chemotherapy or 
clinical evidence suggestive of an alternative diagnosis including pneumonia.
!
Heavily pretreated SCLC patients and patients with a history of pneumonitis may be at 
increased risk, and careful monitoring for signs and symptoms of pneumonitis is 
important. The risk of pneumonitis is increased with prior radiation to lung.
!
In general signs and symptoms coinciding with or preceding pneumonitis may include 
new or worsening cough, chest pain and/or shortness of breath, fever, and radiographic 
changes (reticular markings, ground glass opacities). Protocol defined disease 
assessments provide for the opportunity for on study pulmonary monitoring for detection 
of pneumonitis. The protocol allows for additional imaging per physician discretion for 
signs and symptoms of pulmonary toxicity.

!
The diagnosis of drug induced pneumonitis is one of exclusion. Other etiologies 
including infection, which is a common cause of pulmonary infiltrates with clinical and 
radiographic appearance similar to drug-induced pneumonitis, need to be carefully 
considered and excluded before the diagnosis of drug induced pneumonitis can be 
established.
!
If pneumonitis is suspected, close monitoring including additional laboratory and 
imaging investigation per institutional guidelines may be necessary. Systemic 
corticosteroids may be beneficial for rapidly progressive or more severe pneumonitis.
For Grade 1 pneumonitis, monitor closely. For dose modification, please see Table 5-1 of the 
protocol.

Treatment Compliance
Study drug administration must be performed by study site staff and documented in source

Study Assessments
7.1
Screening/Baseline Assessments
Only subjects who meet all inclusion and exclusion criteria specified in Section 4 (and 
Appendix 13.7, for prostate cancer subjects) will be enrolled in this study.
Absence of active CNS tumor or metastases will be confirmed by MRI of the brain. CT of the 
brain with intravenous contrast may be substituted at the discretion of the Investigator.
Demographics include age, gender, and race.
Subject medical history includes a thorough review of significant past medical history, current 
conditions, smoking history, any diagnosis and treatment for prior malignancies, including 
response to treatment, and any concomitant therapies.
Malignancy history should include tumor type, stage, grade and grading system, sites of 
metastases, and mutational status. The latter should include, at least, status of BRAF for 
melanoma subjects, and RET for MTC subjects.
Standard of Care procedures completed prior to the subject signing ICF, but within the study 
screening window, may be used as screening procedures.
7.1.1
Central Immunohistochemistry Assessment 
For all subjects, tumor tissue representative of the qualifying malignancy must be submitted to a 
central laboratory for determination of DLL3 expression. An archived tumor specimen, or a fresh 
specimen, obtained via on-study biopsy, may be used. DLL3 positivity, for purposes of 
eligibility, will be defined as staining in ≥1% tumor cells. The central assessment will be 
definitive regarding DLL3 expression, which will be relayed to the Investigator. All decisions 
regarding study eligibility will be based upon DLL3 expression adjudicated by this central 
assessment.
7.2
Safety Assessments
In addition to the surveillance and recording of AEs, the assessment of safety during the course 
of this study will consist of the recording of concomitant therapies, protocol-specified physical 
examination findings including vital signs, daily weight diary, ECOG performance status, 
disease assessments, and diagnostic testing (including laboratory testing, radiographic imaging, 
ECGs and ECHOs).
Safety will be monitored over the course of the study by an SMC.
7.2.1
Physical Examination
Physical examinations will include assessments of the head and neck, heart, lungs, abdomen, 
extremities, neurological and skin.

7.2.2
Vital Signs, Weight and Height
Vital signs will include heart rate, respirations, blood pressure, temperature, and weight. All vital 
signs should be measured after the subject has been sitting/resting for at least 5 minutes. For 
adult subjects (>18 years), measurements of height obtained within the prior 6 months may be 
utilized. In the event of an infusion reaction or hypersensitivity reaction, vital signs should be 
monitored more frequently than originally scheduled and as clinically indicated.
Weight will be measured at the times indicated, preferably without outer garments such as hats, 
coats or shoes. Measurements while in light indoor clothing only, or undergarments only, are 
acceptable; but every effort should be made to measure subjects in the same or similar clothing, 
including any accessories or jewelry, at each assessment.
7.2.3
Clinical Laboratory Tests
Laboratory assessments will be performed to evaluate safety at scheduled time points (refer to 
Appendix 13.1) during the course of the study. The following assessments will be performed at 
the local laboratory:
!
CBC, including white blood cell (WBC) count with five-part differential (neutrophils, 
lymphocytes, monocytes, eosinophils, and basophils), red blood cell (RBC) count, 
platelet count, hemoglobin, and hematocrit.
!
Chemistry panel, including electrolytes (sodium, potassium, chloride, and carbon 
dioxide), creatinine, blood urea nitrogen (BUN), calcium, phosphorus, magnesium, 
estimated glomerular filtration rate, glucose, albumin, total protein, amylase, lipase, and 
liver function tests (total and direct bilirubin, ALT, AST, alkaline phosphatase, lactate 
dehydrogenase [LDH]).
!
Coagulation tests, including prothrombin time (PT), activated partial thromboplastin time 
(aPTT)/partial thromboplastin time (PTT), and INR.
!
Urinalysis, including dipstick results for color, appearance, specific gravity, pH, glucose, 
bilirubin, ketones, occult blood, and protein; as well as untimed (spot) analysis of protein 
and creatinine for ratio.
!
Hepatitis B and C tests include Hep B surface antigen (HBsAg), Hep B surface antibody 
(HBsAb), Hep B core antibody (HBcAb) and hepatitis C virus (HCV) antibody. Results 
that may be consistent with chronic or active infection, and/or subjects with known prior 
active hepatitis B or C infection, should undergo polymerase chain reaction (PCR) tests 
for Hep B and/or C, respectively.
!
Pregnancy test, consisting of blood or urine testing for beta-human chorionic 
gonadotropin (∀-hCG). Repeat testing may be performed as requested by the Investigator.

7.2.4
Electrocardiograms
Throughout the study, subjects will be monitored for changes in cardiac conduction through 
ECGs. ECGs will be done in triplicate at the times indicated in Appendices 13.1 and 13.2.
7.2.5
Echocardiogram
ECHOs will be performed at the indicated times (Appendix 13.1) to assess any pericardial 
effusions, if present, as well as cardiac function (left ventricular ejection fraction, LVEF).
7.2.6
ECOG Performance Status
ECOG performance Status (Appendix 13.3) will be evaluated at protocol-specific time points 
(Appendix 13.1).
7.2.7
Fluid Retention Questionnaire
Throughout the treatment period, subjects will be asked about the development of any new or 
worsening peripheral edema or dyspnea (Appendix 13.9). This assessment may take place 
virtually (e.g., by phone).
7.2.8
Daily Weight Diary
Throughout the treatment period, subjects will maintain a diary of daily weights.
7.2.9
Pregnancy Testing
In WOCBP, pregnancy testing will be conducted at scheduled time points during screening and 
the course of the study (refer to Appendix 13.1). Contraception recommendations are outlined in 
Section 4.3.
7.3
Radiographic Response/Efficacy Assessments
Radiographic evaluations at protocol-specified time points include:
!
CT scans of the chest, abdomen and pelvis (scans of the neck must also be obtained 
for MTC and/or if there is documented or suspected involvement in this region)
!
MRI of the brain, if indicated. CT of the brain with intravenous contrast may be 
substituted at the discretion of the Investigator.
!
Whole-body technetium-99m (99mTc) bone scintigraphy (prostate cancer subjects only)
Diagnostic quality, spiral CT scans are recommended; other methods may be used if performed 
consistently throughout the study for each individual subject. Positron emission tomography 
(PET) and/or octreotide/somatostatin scans may be used in an ancillary manner; however, no 
decisions relating to PD may be made based on PET or octreotide/somatostatin scans alone. 
Clinical response will be determined by the Investigator at each assessment according to 
RECIST v1.1 (Appendix 13.6; Eisenhauer 2009), and/or for prostate cancer subjects, PCWG3 
criteria (Appendix 13.7).

For tumors to be assigned a status of responder (PR or CR), changes in tumor measurements 
must be confirmed by repeat assessments performed no less than 4 weeks, but preferably not 
more than 6 weeks, after the criteria for response are first met; i.e., two consecutive assessments 
of PR or CR are required. In instances where a follow-up visit is not otherwise scheduled to 
occur for more than 6 weeks, repeat radiographic disease assessments should be conducted at 
least 4 but not more than 6 weeks after the criteria for response are first met, in order to confirm 
response, whether or not a formal follow-up visit is conducted at the same time.
7.3.1
Radiographic Disease Progression
Radiographic PD will be defined as either of the following:
!
PD by RECIST v1.1 (refer to Appendix 13.6)
!
Confirmed PD by Bone Scan (for prostate cancer subjects using PCWG3 criteria; 
Appendix 13.7)
Treatment beyond what would be considered PD using RECIST v1.1 or PCWG3 is permitted if 
the following criteria, as assessed by the Investigator, are met:
!
Ongoing clinical benefit, without rapid PD
!
Subject continues to meet all other study protocol eligibility criteria
!
Tolerance of study drug
!
Stable ECOG performance status
Treatment beyond progression must not delay an imminent intervention to prevent serious 
complications of PD (e.g., CNS metastases).
Subjects’ clinical data must be available for CRF source verification. Copies of tumor images 
must be made available for review by the Sponsor or its designee upon request.
7.3.2
Patient Reported Outcomes
PROs will be evaluated for subjects in Part B of the study (only) by assessment of health-related 
quality of life and symptoms using the EORTC QLQ-C30 and EQ-5D-5L questionnaires. The 
questionnaires will be completed during screening, Cycle 2 (Days 1 and 29), and EOT (as 
outlined in the Schedule of Assessments Appendix 13.1). Additional details regarding the 
questionnaires are provided in Section 10.3.9.
7.4
Pharmacokinetic Assessments
Blood samples for PK and ATA testing will be collected throughout the study as indicated in 
Appendices 13.1 and 13.2.
Sensitive, qualified assays will be used to measure plasma concentrations of rovalpituzumab 
tesirine ADC (SC16LD6.5).  Plasma concentrations of rovalpituzumab total antibody and blood 
concentrations of SC-DR002, the small molecule component of rovalpituzumab tesirine, may

also be measured if deemed necessary and appropriate. A qualified immunoassay will be used to 
assess ATA against rovalpituzumab tesirine.
7.5
Pharmacodynamic and Biomarker Assessments
Blood and/or tissue samples for pharmacodynamics and biomarker testing will be collected at the 
time points throughout the study as indicated in Appendices 13.1 and 13.2. Refer to the 
laboratory manual for additional details.
AbbVie (or people or companies working with AbbVie) will store the samples in a secure 
storage space with adequate measures to protect confidentiality. The samples may be retained 
while research on rovalpituzumab tesirine (or drugs of this class) or this disease and related 
conditions continues, but for no longer than 20 years after study completion, or per local 
requirement.
7.5.1
Tumor Tissue
Tumor tissue, consisting of a representative archived specimen, or a fresh tumor biopsy, will be 
assessed at baseline for expression of DLL3 by methods such as but not necessarily limited to 
immunohistochemistry (Section 7.1.1). Additional studies, such as routine hematoxylin and eosin 
for morphology and histological classification, IHC for confirmation of diagnosis (e.g., for 
synaptophysin, chromogranin-A, or CD56 for neuroendocrine tumors, or HMB45, S100, or 
MART-1 for melanoma), or scoring of immune infiltrates (e.g., IHC for CD3+, CD4+, CD8+, 
and Foxp3+ cells) may be performed. Tumor material may also be utilized for exploratory 
research that includes assessments of nucleic acid or protein based biomarkers of drug 
sensitivity, resistance, or disease biology and development of a companion diagnostic assay. 
At PD, an optional tumor biopsy may be performed for the assessment of expression of DLL3 
and/or execution of additional studies, such as but not necessarily limited to scoring of immune 
infiltrates or assessment of molecular pathways related to the response to rovalpituzumab 
tesirine. Tumor material may also be utilized for exploratory research that includes assessments 
of nucleic acid or protein based biomarkers of drug sensitivity, resistance, or disease biology and 
development of a companion diagnostic assay. Additional instructions will be provided in the 
laboratory manual.
7.5.2
Inflammatory Markers
At the indicated times, blood will be collected for local testing of inflammatory markers, 
including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), antinuclear antibodies 
(ANA), and rheumatoid factor (RF).
7.5.3

Complaints
A complaint is any written, electronic, or oral communication that alleges deficiencies related to 
the physical characteristics, identity, quality, purity, potency, durability, reliability, safety, 
effectiveness, or performance of a product/device after it is released for distribution.
The investigational product in this study is defined as rovalpituzumab tesirine. Complaints
associated with any component of this investigational regimen must be reported to the Sponsor 
(Section 8). For AEs, please refer to Section 8.1. For product complaints, please refer to 
Section 8.2.
8.1
Medical Complaints
The Investigator will monitor each subject for clinical and laboratory evidence of AEs on a 
routine basis throughout the study. The Investigator will assess and record any AE in detail, 
including the date of onset, event diagnosis (if known) or sign/symptom, severity, time course 
(end date, ongoing, intermittent), relationship of the AE to study drugs, and any action(s) taken. 
For SAEs considered as having "no reasonable possibility" of being associated with study drugs, 
the Investigator will provide another cause of the event. For AEs to be considered intermittent, 
the events must be of similar nature and severity. AEs, whether in response to a query, observed 
by site personnel, or reported spontaneously by the subject will be recorded.
All AEs will be followed to a satisfactory conclusion.
8.1.1
Definitions
8.1.1.1
Adverse Events
An AE is defined as any untoward medical occurrence in a patient or clinical investigation 
subject administered a pharmaceutical product and which does not necessarily have a causal 
relationship with this treatment. An AE can therefore be any unfavorable and unintended sign 
(including an abnormal laboratory finding), symptom, or disease temporally associated with the 
use of a medicinal (investigational) product, whether or not the event is considered causally 
related to the use of the product.
Such an event can result from use of the drug as stipulated in the protocol or labeling, as well as 
from accidental or intentional overdose, drug abuse, or drug withdrawal. Any worsening of a 
pre-existing condition or illness is considered an AE.
Worsening in severity of a reported AE should be reported as a new AE. Laboratory 
abnormalities and changes in vital signs are considered to be AEs only if they result in 
discontinuation from the study, necessitate therapeutic medical intervention (including 
interruption/dose reduction of study drug, starting or discontinuing medication, etc.), meets 
protocol specific criteria (refer to Sections 5.5 and 8.1 regarding toxicity management) and/or if 
the Investigator considers them to be AEs.

An elective surgery/procedure scheduled to occur during a study will not be considered an AE if 
the surgery/procedure is being performed for a pre-existing condition and the surgery/procedure 
has been pre-planned prior to study entry. However, if the pre-existing condition deteriorates 
unexpectedly during the study (e.g., surgery performed earlier than planned), then the 
deterioration of the condition for which the elective surgery/procedure is being done will be 
considered an AE.
All protocol-related AEs must be collected from the signing of the study specific informed 
consent until study drug administration.
In addition, AEs with onset or worsening reported by a subject from the time that the first dose 
of study drug is administered until 70 days have elapsed following discontinuation of study drug 
administration will be considered as TEAEs.
8.1.1.2
Serious Adverse Events
If an AE meets any of the criteria outlined in Table 8-1, the AE is to be reported to AbbVie as an 
SAE within 24 hours of the site being made aware of the SAE.
Table 8-1
Criteria for a Serious Adverse Event (SAE)
Death of Subject
An event that results in the death of a subject.
Life Threatening
An event that, in the opinion of the Investigator, would have resulted in immediate 
fatality if medical intervention had not been taken. This does not include an event 
that would have been fatal if it had occurred in a more severe form.
Hospitalization or 
Prolongation of 
Hospitalization
An event that results in an admission to the hospital for any length of time or 
prolongs the subject's hospital stay. This does not include an emergency room visit 
or admission to an outpatient facility, or hospitalization for respite care.
Congenital Anomaly
An anomaly detected at or after birth, or any anomaly that results in fetal loss.
Persistent or Significant 
Disability/Incapacity
An event that results in a condition that substantially interferes with the activities 
of daily living of a study subject. Disability is not intended to include experiences 
of relatively minor medical significance such as headache, nausea, vomiting, 
diarrhea, influenza, and accidental trauma (e.g., sprained ankle).
Important Medical Event 
Requiring Medical or 
Surgical Intervention to 
Prevent Serious Outcome
An important medical event that may not be immediately life threatening or result 
in death or hospitalization, but based on medical judgment may jeopardize the 
subject and may require medical or surgical intervention to prevent any of the 
outcomes listed above (i.e., death of subject, life threatening, hospitalization, 
prolongation of hospitalization, congenital anomaly, or persistent or significant 
disability/incapacity). Additionally, any elective or spontaneous abortion or 
stillbirth is considered an important medical event. Examples of such events 
include allergic bronchospasm requiring intensive treatment in an emergency room 
or at home, blood dyscrasias or convulsions that do not result in inpatient 
hospitalization, or the development of drug dependency or drug abuse.
Note: For SAEs with the outcome of death, the date and cause of death will be recorded on the appropriate CRF.

8.1.1.3
Adverse Events Expected Due to Cancer Progression
The term "disease progression" alone should not be used when reporting AEs or SAEs, due to its 
lack of specificity. Rather, symptoms of disease progression (PD) should be collected under the 
unifying diagnosis of "malignant neoplasm progression;" symptoms of progression may be 
subsumed under this diagnosis.
8.1.2
Adverse Event Severity
The Investigator will rate the severity of each AE according to the NCI CTCAE v4.03. If a 
reported AE increases in severity, the initial AE should be given an outcome date and a new AE 
reported on a different date from the end date of the previous AE to reflect the change in 
severity. For all reported SAEs that increase in severity, the supplemental eCRFs also need to be 
updated to reflect the change in severity.
When CTCAE criteria cannot be used, the event should be graded as defined below:
Grade 1
The adverse event is transient and easily tolerated by the subject (mild).
Grade 2
The adverse event causes the subject discomfort and interrupts the subject's 
usual activities (moderate).
Grade 3/4
The adverse event causes considerable interference with the subject's usual 
activities and may be incapacitating or life threatening (severe). 
Grade 5
The adverse event resulted in death of the subject (severe).
8.1.3
Relationship to Study Drug
The Investigator will use the following definitions to assess the relationship of the AE to the use 
of study drug:
Reasonable Possibility
After consideration of factors, including timing of the event, 
biologic plausibility, clinical judgment, and potential alternative 
causes, there is sufficient evidence (information) to suggest a 
causal relationship.
No Reasonable Possibility
After consideration of factors, including timing of the event, 
biologic plausibility, clinical judgment, and potential alternative 
causes, there is insufficient evidence (information) to suggest a 
causal relationship
For causality assessments, events assessed as having a reasonable possibility of being related to 
the study drug will be considered "associated." Events assessed as having no reasonable 
possibility of being related to study drug will be considered "not associated." In addition, when 
the Investigator has not reported a causality or deemed it not assessable, AbbVie will consider 
the event associated.

Page 58 of 111
Confidential
If an Investigator's opinion of no reasonable possibility of being related to study drug is given, an 
“Other” cause of event must be provided by the Investigator for the SAE.
8.1.4
Deaths
For SAEs with the outcome of death, the date and cause of death will be recorded on the 
appropriate case report form.
Deaths that occur during the protocol specified AE reporting period (Section 8.1.5) that are more 
likely related to PD will therefore be considered as an expected AE and will not be subject to 
expedited reporting to regulatory agencies. These SAEs should be reported as “malignant 
neoplasm progression” and also recorded on the AE eCRF. After the AE reporting period, deaths 
attributed to PD under study should be recorded only on the end of study (EOS) eCRF.
Death should be considered an outcome and not a distinct event. The event or condition that 
caused or contributed to the fatal outcome should be recorded as the single medical concept on 
the AE eCRF. Generally, only one such event should be reported. The term "sudden death" 
should only be used for the occurrence of an abrupt and unexpected death due to presumed 
cardiac causes in a patient with or without pre-existing heart disease, within 1 hour of the onset 
of acute symptoms or, in the case of an unwitnessed death, within 24 hours after the patient was 
last seen alive and stable. If the cause of death is unknown and cannot be ascertained at the time 
of reporting, "unexplained death" should be recorded on the AE eCRF. If the cause of death later 
becomes available (e.g., after autopsy), "unexplained death" should be replaced by the 
established cause of death.
8.1.5
Adverse Event Collection Period
All AEs reported from the time of study drug administration until 70 days following 
discontinuation of study drug administration will be collected, whether solicited or 
spontaneously reported by the subject. In addition, protocol-related serious and non-serious AEs 
will be collected from the time the subject signed the study-specific informed consent.
Serious and non-serious AEs occurring after the study-specific informed consent is signed but 
prior to the initial dose of study drug will be collected only if they are considered by the 
Investigator to be causally related to the study-required procedures.
AE information will be collected as shown in Figure 8-1.

Pregnancy Reporting
Pregnancy in a study subject must be reported to the Sponsor within 24 hours of the site 
becoming aware of the pregnancy. Subjects who become pregnant during the study must be 
discontinued.
All subjects should be informed that contraceptive measures (refer to Section 4.3 Contraception 
Recommendations) should be taken throughout the study and for at least 6 months after the last 
dose of study drug. Male subjects should be informed that contraceptive measures should be 
taken by their female partner. 
Information regarding a pregnancy occurrence in a study subject and the outcome of the 
pregnancy will be collected. In the event of a pregnancy occurring in the partner of an enrolled 
subject, written informed consent for release of medical information from the partner must be 
obtained prior to the collection of any pregnancy-specific information, and the pregnancy will be 
followed to outcome. In the event a study subject or the partner of an enrolled subject delivers a 
baby, they will be asked to provide information including the following will be requested: date of 
delivery, birth weight and length, boy or girl, problems during pregnancy or delivery, and if the 
baby has any birth defects.
Pregnancy in a study subject is not considered an AE. However, the medical outcome of an 
elective or spontaneous abortion, stillbirth or congenital anomaly is considered an SAE and must 
be reported to AbbVie within 24 hours of the site becoming aware of the event.

Product Complaint
8.2.1
Definition
A Product Complaint is any Complaint (refer to Section 8 for the definition) related to the 
biologic or drug component of the product or to the medical device component(s).
For a product this may include, but is not limited to, damaged/broken product or packaging, 
product appearance whose color/markings do not match the labeling, labeling 
discrepancies/inadequacies in the labeling/instructions (example: printing illegible), missing 
components/product, device not working properly, or packaging issues.
Any information available to help in the determination of causality to the events outlined directly 
above should be captured.
8.2.2
Reporting
Product Complaints concerning the investigational product must be reported to the Sponsor 
within 24 hours of the study site's knowledge of the event via the Product Complaint form. 
Product Complaints occurring during the study will be followed-up to a satisfactory conclusion. 
All follow-up information is to be reported to the Sponsor (or an authorized representative) and 
documented in source as required by the Sponsor. Product Complaints associated with AEs will 
be reported in the study summary. All other complaints will be monitored on an ongoing basis.
Product Complaints may require return of the product with the alleged complaint condition. In 
instances where a return is requested, every effort should be made by the Investigator to return 
the product within 30 days. If returns cannot be accommodated within 30 days, the site will need 
to provide justification and an estimated date of return.
The description of the complaint is important for AbbVie in order to enable AbbVie to 
investigate and determine if any corrective actions are required.
8.2.3
Events Commonly Associated in Study Population with Advanced Solid Tumors 
and/or Progression of Underlying Malignancy
Certain AEs are anticipated to occur in the study population at some frequency independent of 
drug exposure. Such events include known consequences of the underlying disease or condition 
under investigation (e.g., symptoms, PD).
A list of AEs associated with advanced solid tumors is provided in Appendix 13.10. These AEs 
are preferred terms coded according to the latest version of the Medical Dictionary for 
Regulatory Activities (MedDRA) dictionary; the AEs may occur alone or in various 
combinations and are considered expected for reporting purposes for this protocol. Although 
exempted from expedited reporting to Health Authorities and IRBs as individual cases, if these 
AEs meet serious criteria these SAEs must be reported to AbbVie within 24 hours of the site

being made aware of the SAE (as required in Section 8.1.6). For deaths related to disease 
progression (coded to malignant neoplasm progression), the date and cause of death will be 
recorded on the appropriate case report form (CRF), but the event will not be expedited as an 
Individual Case Safety Report (ICSR) to regulatory authorities (Section 8.1.4).
8.3
Appropriateness of Measurements
The safety measures that will be used in this trial are considered standard procedures for 
evaluating the potential adverse effects of study medications. AEs and, when applicable, clinical 
laboratory data will be graded using NCI CTCAE, version 4.03.
Response will be assessed according to RECIST v1.1 (Eisenhauer 2009), which includes 
standard criteria for evaluating response in solid tumors. Prostate cancer is assessed by PCWG3 
criteria. The intervals of evaluation in this protocol are appropriate for disease management.
Standard tests will be performed to detect the possible presence of specific antibodies to study 
drug. PK assessments for drug activity are also common in clinical studies.

Data Handling and Recordkeeping
9.6.1
Data Handling
It is the Investigator’s responsibility to ensure the accuracy, completeness, legibility, and 
timeliness of the data reported to the Sponsor in the CRFs and in all required reports. The CRFs 
should be captured in the Sponsor EDC system within ten (10) business days of the subject’s 
visit to the site. Data reported on the CRF that is derived from source documents should be 
consistent with the source documents or the discrepancies must be explained.
Any change or correction to a CRF must be maintained in an audit trail within the electronic data 
capture system. Data changes may only be made by those individuals so authorized. The 
Investigator must retain records of the changes and corrections, written and/or electronic. Prior to 
database lock the Investigator must review and approve the completed electronic CRFs to verify 
their accuracy.
9.6.2
Investigator Record Retention
The Investigator shall retain study drug disposition records and all source documentation (such 
as original ECG tracings, laboratory reports, and in-patient or office patient records) for the 
maximum period required by the country and institution in which the study will be conducted, or 
for the following periods, whichever is longer: for at least 2 years after the last approval of a 
marketing application in an International Conference on Harmonisation (ICH) region and until 
there are no pending or contemplated marketing applications in an ICH region or for at least 
2 years after the relevant authority has been informed of the discontinuation of clinical 
development of the study drug. The Investigator may not destroy any records associated with the 
study without obtaining the prior, written consent of the Sponsor. If the Investigator withdraws 
from the study (due to relocation, retirement, etc.), the records will be transferred to a mutually 
agreed upon designee, such as another Investigator or IRB/IEC. No records shall be transferred 
without prior, written authorization from the Sponsor or its designee.

Data Analysis and Statistical Methods
This section provides the key details of the statistical analyses to be performed using data 
captured according to this protocol. Further details on planned analyses for the data captured in 
this protocol will be provided in the Statistical Analysis Plan (SAP).
10.1
Determination of Sample Size
Up to approximately 318 subjects are expected to participate in this two-part trial.
In Part A, up to approximately 144 subjects may be enrolled, assuming 3 dose-escalation cohorts 
of 6 subjects each (18 subjects) across 8 disease cohorts. The exact number will depend on the 
number of cohorts required to reach the MTD in each disease, and the number of subjects 
enrolled in each disease-specific cohort. 
In Part B, up to approximately 174 subjects may be enrolled, including approximately 
19 subjects in each of the 5 disease-specific cohorts. The rationale for the sample size is based on 
the assumption that an ORR of around 15% would be indicative of efficacy worthy of further 
investigation given the advanced cancers and extensive treatment history in this study 
population. Additionally, an ORR below 5% would provide evidence of an ineffective treatment. 
The goal of the efficacy analyses is to provide a preliminary signal that the response rate may 
potentially be within that target range.
When Part B is enrolled, each disease-specific cohort will have approximately 25 subjects treated 
at the RP2D, including the Part A and Part B subjects. Table 10-1 presents the 90% two-tailed 
lower exact confidence limits for selected response rates.
Table 10-1

5.7%
The final decision to pursue the clinical development of any disease-specific cohort will be based 
on safety evaluations, the complete results of the study, and other factors; fewer than 3 responses 
could be considered a discouraging result. When 3 or more responses are observed, there is 
approximately a 75% probability this occurs when the true rate is 15%, but less than 13% when 
the true rate is 5%. When 4 responses are observed, a 5% rate is excluded by the 90% confidence 
interval (CI) lower bound.

An interim futility analysis is planned for each cohort, which may have an impact on the number 
of subjects ultimately enrolled in Part B. The futility analysis is described in Section 10.3.6.
!
The Other NEC/NET and Other Solid Tumor cohorts will enroll subjects until all other 
disease cohorts complete enrollment, and are expected to enroll approximately 30 subjects 
each by the time of study completion.
!
Details will be provided in the SAP.
10.2
Analysis Populations
The following populations will be considered:
!
Full Analysis Set: All enrolled subjects who receive any amount of study drug.
!
Safety Set: All subjects who receive any amount of study drug and have at least one 
post-baseline safety evaluation.
!
DLT-Evaluable Set: All subjects who receive any amount of study drug and either 
experienced a DLT or were followed for the full DLT evaluation period.
!
Pharmacokinetic-Evaluable Set: All subjects who receive at least 1 dose of study drug 
and for whom a baseline measurement and at least one blood sample following a dose of 
study treatment are available.
Based on the actual deviations, the criteria for exclusion of subjects from the different data sets 
will be specified and updated, if necessary, prior to database lock.
10.3
Planned Analyses
As a general strategy, continuous efficacy and safety endpoints will be summarized using the 
five-number summary (mean, standard deviation, median, minimum, and maximum). Frequency 
distributions (counts and percentages) will be used to summarize categorical endpoints.
10.3.1 Disposition of the Study Subjects
The disposition of subjects will be described with summaries by disease and cohort of the 
number of subjects enrolled, the number of subjects treated, the number of subjects for whom 
study drug was permanently discontinued (including the reasons for discontinuation), and the 
number of subjects who discontinued early from the study.
10.3.2 Demographic and Baseline Characteristics
Demographic and baseline characteristics will be summarized and compared by disease and 
cohort. Results will be reported using subjects in the full analysis set.
10.3.3 Exposure to Study Treatment and Compliance
Frequency distributions of the number of received doses will be presented by disease and cohort. 
Treatment duration and treatment compliance for all randomized subjects will be described by

disease and cohort.
10.3.4 Analysis of Primary Efficacy Endpoints
The first primary efficacy endpoints are the best objective response rate based on RECIST v1.1 
and/or, for prostate cancer subjects, PCWG3 criteria. It is defined as the proportion of subjects 
whose best overall response is either CR or PR according to RECIST v1.1 or PCWG3. The best 
overall response is the highest recorded response through End of Treatment. The number and 
percentage of responders along with the corresponding 90% two-tailed CI will be provided for 
each disease and cohort.
10.3.5 Analysis of Secondary Efficacy Endpoints
The analysis of the secondary efficacy endpoints will be conducted using data from the Full 
Analysis set.
Burden of disease will be analyzed in a way similar to the analysis of the best ORR (described in 
the previous section).
DOR will be summarized for responders (i.e., subjects with CR or PR only) by disease and 
cohort. PFS and OS will be summarized by disease and cohort. The PFS rate at additional time 
points may also be evaluated (e.g., 26, 39 and 52 weeks). DOR, and PFS, will be obtained by 
using the Kaplan-Meier approach similar to OS described in the previous section. 
Details of the analysis of secondary efficacy endpoints will be described in the Statistical 
Analysis Plans.
10.3.6 Futility Analysis
A non-binding futility analysis is planned for each cohort when 12 subjects have at least 
2 evaluable tumor response evaluations after starting therapy. This analysis is designed to give a 
timely preliminary signal of response to consider along with cohort safety data to assess the 
advisability of continuing to enroll the cohort. Reported probabilities are based on exact 
calculations. There is a 54% chance that a result of 0 responses is observed when the true 
response rate is 5%. When the response rate in the population is the target rate of interest (15%); 
the chance of 0 responses is 14%, 1 response 30%, and 1 or more responses 96%. Therefore, 
observing 1 or more responses at the interim analysis would be supportive of further enrollment.
10.3.7 Safety Analysis
Safety endpoints will be summarized using data from the Safety Set. Safety analyses will involve 
examination of the incidence, severity, and type of TEAEs reported, changes in vital signs and 
laboratory test results from baseline (the assessment prior to first dose) to specified time points 
throughout the study, and concomitant medications use.

same organ class and preferred term, the most severe event will be presented.
10.3.7.2 Clinical Laboratory Evaluation
Laboratory parameters will be summarized by disease and cohort at each visit. Each summary 
will include the values of the laboratory parameters and their change from baseline. Shift tables 
from baseline will be presented for laboratory values in the chemistry and hematology panels. 
Parameters will be classified according to the laboratory reference normal ranges. A listing will 
be provided for out of normal range as well as clinically significant abnormal lab values.
10.3.7.3 Vital Signs
Vital signs, including pulse, blood pressure, temperature, height, and body weight will be 
summarized by disease and cohort and time point. For each assessment of vital signs, change and 
percent change in vital signs from baseline will be summarized by disease and cohort.
10.3.7.4 Eastern Cooperative Oncology Group Performance Status
ECOG performance status will be summarized for each visit by disease and cohort. Shifts from 
baseline to the best and worst post-baseline score may be tabulated.
10.3.7.5 Electrocardiogram
Electrocardiogram status will be summarized for each scheduled visit by disease and cohort. 
Shifts from baseline may be tabulated. Additionally, ECG parameters will be described using the 
five-number summary.

sorted by the incidence use of the entire sample.
10.3.8 Pharmacokinetic and Pharmacodynamics Analyses
Data from the Pharmacokinetic-Evaluable Set will be used in the analysis of PK and 
Pharmacodynamics endpoints. The PK of rovalpituzumab tesirine will be estimated from 
concentration-time data using non-compartmental methods. The reporting of PK parameters will 
be determined based on the final parameter analysis on the available data. The PK parameters 
that may be assessed include, as appropriate:

Volume of distribution 
The above parameters will be summarized by descriptive statistics.
The incidence and timing of ATA to study drug will be summarized by descriptive statistics. The 
possible effects of ATA on PK, efficacy and safety may be explored. Details will be provided in 
the SAP.
The five-number summary will be used to describe absolute and percent change from baseline in 
IHC, blood tumor markers (like NSE), soluble biomarkers (such as soluble DLL3) and 
circulating tumor cells. Regressions may be performed as appropriate. Exploratory analyses may 
be performed to evaluate a possible correlation between each of these endpoints and disease 
response and/or toxicities. Additional analyses may also be performed. Details will be provided 
in the SAP.
10.3.9 Patient Reported Outcomes (PROs)
PROs will be evaluated for subjects in Part B of the study (only) by assessment of health-related 
quality of life and symptoms using the EORTC QLQ-C30 and EQ-5D-5L questionnaires. The 
questionnaires will be completed according to Section 7.3.2 (and as outlined in the Schedule of 
Assessments, Appendix 13.1). The EORTC QLQ-C30 is a cancer-specific instrument that has 
30 items and 5 functional domain scales: Physical, Role, Emotional, Social, and Cognitive; 
2 items evaluate global quality of life. The EQ-5D-5L is a generic preference instrument that has 
been validated in numerous populations. The EQ-5D-5L is composed of 5 questions and a visual 
analog scale (VAS) assessing overall health that can be converted into a single health status or

Ethical and Regulatory Considerations
This study will be conducted in accordance with ICH Guidance E6 (R1) (ICH 1996); FDA CFR 
[21 CFR Parts 50, 56, and 312]); Declaration of Helsinki World Medical Association 
Recommendations Guiding Physicians in Biomedical Research Involving Human Subjects, as it 
may be amended; applicable data protection laws and regulations; and all laws, rules, and 
regulations applicable to the study or the study drug in jurisdictions in which the Investigator 
conducts the study. 
11.1
Informed Consent
The Investigator is responsible for presenting the risks and benefits of study participation, along 
with the aims and methods of the study, to the subject in terms understandable to the subject 
using the IRB/IEC approved Informed Consent Form (ICF). The Investigator will also instruct 
the subjects that they are free to withdraw their consent and discontinue their participation in the 
study at any time without prejudice. The Investigator or his/her designee shall re-consent 
subjects when the ICF is updated during the study, if required. The Investigator will ensure that 
written informed consent is obtained from each subject or their legally authorized representative, 
if applicable to this study, by obtaining the signature and date on the ICF prior to the 
performance of protocol evaluations or procedures.
The ICF will document the study-specific information the Investigator or his/her designee 
provides to the subject and the subject’s agreement to participate in the study and to comply with 
the instructions of the Investigator and study staff. Informed consent will be verified and 
countersigned by the Investigator or their designee. If informed consent is obtained from a 
legally authorized representative for a subject who is unable to provide informed consent at study 
entry but the subject is later able to provide informed consent, the Investigator must obtain 
written informed consent from the subject using the IRB/IEC approved ICF.
Prior to the start of the study, the Investigator will provide the Sponsor with an ICF approved by 
the IRB/IEC for use during the study that is based on Sponsor’s model template ICF. The model 
ICF template prepared by the Sponsor will be provided in the study manual. The proposed ICF 
and the informed consent process must comply with US regulations 21 CFR Part 50.25 as well as 
other applicable national and international laws, rules and regulations. The proposed ICF should 
contain the 20 elements of the informed consent described in ICH E6 4.8 and adhere to the 
ethical principles of the Declaration of Helsinki. The ICF must have been reviewed and approved 
by the Sponsor and the study IRB prior to initiation of the study. In addition, any amendments to 
the ICF will need to be approved by the Sponsor and the IRB/IEC. The ICF must contain, or 
subjects must separately be provided with, an authorization for use and disclosure of protected 
health information and include the elements required by 45 CFR Part 164.508(b) for valid 
authorizations.

Previous Protocol (version 3.0) Cohort 3 (Glioblastoma) Specific Guidance
Protocol version 3.0 included eight separate cohorts enrolling in the following cancer types: 
1. Malignant melanoma 
2. Medullary thyroid cancer (MTC)
3. Glioblastoma (GBM)
4. Large cell neuroendocrine carcinoma (LCNEC) of the lung
5. Neuroendocrine prostate cancer (NEPC)
6. High-grade gastroenteropancreatic neuroendocrine carcinoma (GEP NEC) 
7. Other neuroendocrine carcinoma (NEC), and high grade neuroendocrine tumors (NET) 
8. Solid tumors other than the above
13.3.1 Efficacy Endpoint
Response will be assessed by radiographic imaging at protocol-specified time points. Tumor response 
assessments will be conducted every 6 weeks during active study treatment until 24 weeks, then 
every 12 weeks, thereafter. GBM cancer-specific assessments are described below, in Section 13.3.4.
For GBM subjects only, efficacy will be assessed using Response Assessment in Neuro-Oncology 
(RANO) criteria.
13.3.2 Inclusion Criteria
Measurable disease, defined as at least one tumor lesion ≥10mm in the longest diameter, or a lymph 
node ≥15mm in short-axis measurement, assessed by computerized tomography (CT) scan (by 
RECIST v1.1).  Subjects with GBM must have measurable disease by RANO criteria: Measurable 
disease is defined as bidimensionally contrast enhancing lesions with clearly defined margins by CT 
or magnetic resonance imaging (MRI) scan, with two perpendicular diameters of at least 10 mm, 
visible on two or more axial slices that are preferably, at most, 5 mm apart with 0 mm skip.
13.3.3 Study Activities
Subjects enrolled in cohort 3 (GBM) will follow the study activities for subjects in cohorts 1-8, as 
outlined in Section 6 of the protocol (version 4.0), as well as the Schedule of Assessments for cohort 
1-8 subjects (Table 13.1).  Specific considerations for cohort 3 subjects are provided in this 
section 13.3.
13.3.4 Blood Tumor Markers
Blood tumor markers are NOT collected for Cohort 3, Glioblastoma.
13.3.4 Response Assessment in Neuro-Oncology Criteria
Tumor assessments will be assessed using the RANO criteria as outlined below according to Wen, et 
al, "Updated Response Assessment Criteria for High-Grade Gliomas: Response Assessment in 
Neuro-Oncology Working Group."

Table 13-1
Criteria for Determining First Progression Depending on Time from Initial 
Chemoradiotherapy
First Progression
Definition
Progressive disease 
<12 weeks after 
completion of 
chemoradiotherapy
Progression can only be defined using diagnostic imaging if there is new 
enhancement outside of the radiation field (beyond the high-dose region or 80% 
isodose line) or if there is unequivocal evidence of viable tumor on 
histopathologic sampling (e.g., solid tumor areas [i.e., > 70% tumor cell nuclei in 
areas], high or progressive increase in MIB-1 proliferation index compared with 
prior biopsy, or evidence for histologic progression or increased anaplasia in 
tumor).
Note: Given the difficulty of differentiating true progression from 
pseudoprogression, clinical decline alone, in the absence of radiographic or 
histologic confirmation of progression, will not be sufficient for definition 
of progressive disease in the first 12 weeks after completion of concurrent 
chemoradiotherapy.
Progressive disease 
≥12 weeks after 
chemoradiotherapy 
completion
1.
New contrast-enhancing lesion outside of radiation field on decreasing, 
stable, or increasing doses of corticosteroids.
2.
Increase by ≥25% in the sum of the products of perpendicular diameters 
between the first post-radiotherapy scan, or a subsequent scan with smaller 
tumor size, and the scan at 12 weeks or later on stable or increasing doses of 
corticosteroids.
3.
Clinical deterioration not attributable to concurrent medication or comorbid 
conditions is sufficient to declare progression on current treatment but not for 
entry onto a clinical trial for recurrence.
4.
For patients receiving anti-angiogenic therapy, significant increase in 
T2/FLAIR non-enhancing lesion may also be considered progressive disease. 
The increased T2/FLAIR must have occurred with the patient on stable or 
increasing doses of corticosteroids compared with baseline scan or best 
response after initiation of therapy and not be a result of comorbid events 
(e.g., effects of radiation therapy, demyelination, ischemic injury, infection, 
seizures, postoperative changes, or other treatment effects).
FLAIR = fluid-attenuated inversion recovery
Pseudoprogression and Radiation Effects
The proposed new response criteria suggest that within the first 12 weeks of completion of 
radiotherapy, when pseudoprogression is most prevalent, progression can only be determined if the 
majority of the new enhancement is outside of the radiation field (for example, beyond the high-dose 
region or 80% isodose line) or if there is pathologic confirmation of progressive disease. It is 
recognized that the proposed histologic criteria have important limitations, but they provide guidance 
on the type of findings that are suggestive of progressive disease. For patients in whom 
pseudoprogression cannot be differentiated from true tumor progression, enrollment onto trials for 
recurrent gliomas should not be permitted. Patients who remain clinically stable and/or are suspected 
to have pseudoprogression based on metabolic or vascular imaging should continue with their current 
therapy.

Page 87 of 111
Enhancement as a Result of Surgery and Other Therapies
Increased enhancement often develops in the wall of the surgical cavity 48 to 72 hours after surgery. 
To avoid interpretation of postoperative changes as residual enhancing disease, a baseline MRI scan 
should ideally be obtained within 24 to 48 hours after surgery and no later than 72 hours after 
surgery. The inclusion of diffusion weighted imaging in the immediate post-operative MRI scan can 
be helpful in determining whether new enhancement developing in the subsequent weeks or months 
is caused by sequelae of ischemia or by tumor recurrence. In addition, a transient increase in 
enhancement that can be difficult to distinguish from recurrent disease can also occur after locally 
administered therapies. These include chemotherapy wafers, immunotoxins delivered by convection 
enhanced delivery, regionally administered gene and viral therapies, immunotherapies, and focal 
irradiation with brachytherapy and stereotactic radiosurgery. Imaging modalities such as perfusion 
imaging, magnetic resonance spectroscopy, and positron emission tomography scans may sometimes 
be helpful in differentiating treatment effects from recurrent tumor. However, no imaging modality 
currently has sufficient specificity to conclusively differentiate recurrent tumor from treatment 
effects, and surgical sampling may occasionally be needed to obtain a definitive diagnosis.
Definition of Clinical Deterioration
The definition of clinical deterioration is left to the discretion of the treating physician, but it is 
recommended that a decline in the KPS from 100 or 90 to 70 or less, a decline in KPS of at least 20 
from 80 or less, or a decline in KPS from any baseline to 50 or less, for at least 7 days, be considered 
neurologic deterioration unless attributable to comorbid events or changes in corticosteroid dose. 
Similarly, a decline in the Eastern Cooperative Oncology Group and WHO performance scores from 
0 or 1 to 2 or 2 to 3 would be considered neurologic deterioration.
For those subjects who have measurable disease post resection, RANO criteria for assessment of CR, 
PR, SD and PD can be applied. See the below tables for the definitions to be used.
Definition of Radiographic Response
Radiographic response should be determined in comparison to the tumor measurement obtained at 
pretreatment baseline for determination of response, and the smallest tumor measurement at either 
pretreatment baseline should be used for determination of progression. Table 1 lists the criteria for 
radiographic changes after therapy. In the event that the radiographic changes are equivocal and it is 
unclear whether the patient is stable or has developed progressive disease, it is permissible to 
continue treatment and observe the patient closely, for example at 4-week intervals. If subsequent 
imaging studies demonstrate that progression has occurred, the date of progression should be the date 
of the scan at which this issue was first raised. The determination of radiographic response after 
treatment with agents that affect vascular permeability is particularly difficult. In these patients, 
consideration should be given to performing a second scan at 4 weeks to confirm the presence of 
response or stable disease. All measurable and nonmeasurable lesions should be assessed using the 

AbbVie
Rovalpituzumab tesirine (SC16LD6.5)
Version 4.0
Page 88 of 111
same techniques as at baseline. Ideally, patients should be imaged on the same MRI scanner, or at 
least with the same magnet strength, for the duration of the study to reduce difficulties in interpreting 
changes.
Patients with nonmeasurable enhancing disease whose lesions have significantly increased in size and 
become measurable (minimal bidirectional diameter of ≥10 mm and visible on at least two axial 
slices that are preferably, at most, 5 mm apart with 0 mm skip) will also be considered to have 
experienced progression. The transition from a nonmeasurable lesion to a measurable lesion resulting 
in progression can theoretically occur with relatively small increases in tumor size (e.g., a 9 × 9 mm 
lesion [nonmeasurable] increasing to a 10 × 11 mm lesion [measurable]). Ideally, the change should 
be significant (>5 mm increase in maximal diameter or ≥25% increase in sum of the products of 
perpendicular diameters of enhancing lesions). In general, if there is doubt about whether the lesion 
has progressed, continued treatment and close follow-up evaluation will help clarify whether there is 
true progression. If there is uncertainty regarding whether there is progression, the patient may 
continue on treatment and remain under close observation (e.g., evaluated at 4-week intervals). If 
subsequent evaluations suggest that the patient is in fact experiencing progression, then the date of 
progression should be the time point at which this issue was first raised.

Criteria for Response Assessment Incorporating MRI and Clinical Factors
Response
Criteria
Complete Response
Requires all of the following: complete disappearance of all enhancing 
measurable and nonmeasurable disease sustained for at least 4 weeks; no new 
lesions; stable or improved nonenhancing (T2/FLAIR) lesions; patients must be 
off corticosteroids (or on physiologic replacement doses only); and stable or 
improved clinically.
Note:
Patients with nonmeasurable disease only cannot have a complete response; the 
best response possible is stable disease.
Partial Response
Requires all of the following: ≥50% decrease compared with baseline in the sum 
of products of perpendicular diameters of all measurable enhancing lesions 
sustained for at least 4 weeks; no progression of nonmeasurable disease; no new 
lesions; stable or improved nonenhancing (T2/FLAIR) lesions on same or lower 
dose of corticosteroids compared with baseline scan; the corticosteroid dose at 
the time of the scan evaluation should be no greater than the dose at time of 
baseline scan; and stable or improved clinically.
Note:
Patients with nonmeasurable disease only cannot have a partial response; the best 
response possible is stable disease.
Stable Disease
Requires all of the following: does not qualify for complete response, partial 
response, or progression; stable nonenhancing (T2/FLAIR) lesions on same or 
lower dose of corticosteroids compared with baseline scan. In the event that the 
corticosteroid dose was increased for new symptoms and signs without 
confirmation of disease progression on neuroimaging, and subsequent follow-up 
imaging shows that this increase in corticosteroids was required because of 
disease progression, the last scan considered to show stable disease will be the 
scan obtained when the corticosteroid dose was equivalent to the baseline dose.
Progression
Defined by any of the following: ≥25% increase in sum of the products of 
perpendicular diameters of enhancing lesions compared with the smallest tumor 
measurement obtained either at baseline (if no decrease) or best response, on 
stable or increasing doses of corticosteroids; significant increase in T2/FLAIR 
nonenhancing lesion on stable or increasing doses of corticosteroids compared 
with baseline scan or best response after initiation of therapy* not caused by 
comorbid events (e.g., radiation therapy, demyelination, ischemic injury, 
infection, seizures, postoperative changes, or other treatment effects); any new 
lesion; clear clinical deterioration not attributable to other causes apart from the 
tumor (e.g., seizures, medication adverse effects, complications of therapy, 
cerebrovascular events, infection, and so on) or changes in corticosteroid dose; 
failure to return for evaluation as a result of death or deteriorating condition; or 
clear progression of nonmeasurable disease.
MRI = magnetic resonance imaging; FLAIR = fluid-attenuated inversion recovery
*
Stable doses of corticosteroids include patients not on corticosteroids.
Note:
All measurable and nonmeasurable lesions must be assessed using the same techniques as at baseline.

more new lesions is also considered progression.
Stable disease (SD)
Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for 
PD, taking as reference the smallest sum diameters while on study.
New measureable lesions*
Always represents PD.
New nonmeasurable lesions
Always represents PD.
Non-index lesions
Changes contribute to defining best overall response of CR, PR, SD, and PD.
From RECIST v1.1 (Eisenhauer 2009) 
* Measureable lesion must 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 (CT slice thickness ≤5 mm).

Guidance for Subjects with Prostate Cancer
For subjects with prostate cancer, the following prostate-specific guidelines will apply.
Additional Study Population Criteria
The following additional inclusion criteria will be applied to the main study criteria (Section 4):
1.
Prostate cancer of predominantly small cell neuroendocrine (NEPC) and/or intermediate 
atypical carcinoma (IAC) histologic differentiation in a primary or metastatic tumor specimen.
2.
Progressive disease by PCWG3 (Scher 2016), RECIST v1.1 (Eisenhauer 2009), or both criteria 
during or within 4 weeks following completion of at least one prior systemic therapy delivered 
in the metastatic disease setting, including at least one of the following:
a.
Progression of nodal or visceral metastasis (computed tomography [CT] scan or magnetic 
resonance imaging [MRI] according to RECIST v1.1).
b. Development of new sites of visceral or nodal metastases. Previously normal (<1.0 cm) 
lymph nodes must have grown by ≥5 mm in the short axis from baseline or nadir and be 
≥1.0 cm in the short axis to be considered to have progressed. 
c.
Progression of bone disease (at least 2 new bone lesions as measured by bone scan).
3.
Surgically or medically castrated with serum testosterone <50 ng/dL (1.7 nM) at screening. Any 
medical castration therapy (subjects who have not undergone orchiectomy) must have been 
initiated at least 4 weeks prior to Cycle 1 Day 1 and must be continued throughout the duration 
of the study. Subjects with de novo primary small cell carcinoma of the prostate are exempt 
from this criterion.
Duration of Treatment
Subjects will be eligible to continue treatment until unacceptable toxicity, no longer clinically 
beneficial according to PCWG3, withdrawal of consent, or study termination, whichever occurs first. 
In accordance with PCWG3 guidelines, early changes in PSA should not be acted on without other 
evidence of PD, and treatment should be continued for at least 12 weeks to ensure adequate drug 
exposure. 
Allowed Concomitant Therapy
For prostate cancer subjects, ongoing treatment with luteinizing hormone-releasing hormone (LHRH) 
agonists or antagonists, denosumab, or bisphosphonates (e.g., zoledronic acid) is allowed.

13.7.1 Additional Assessments for Subjects with Prostate Cancer
!
Tumor assessments will be performed according to RECIST v1.1 for soft tissue lesions and/or the 
PCWG3 for bone lesions
!
PSA levels will be measured and monitored according to the PCWG3 guidance for PSA
PCWG3 Guidance for Bone Lesions
Assessment of bone lesions will be based on radionuclide scans. The outcome of bone scans should 
be recorded as either “new lesions” or “no new lesions.” 
!
For the first scheduled reassessment, new lesions will require a confirmatory bone scan 6 or more 
weeks later. If new lesions are confirmed, the subject will be defined as disease progression in 
accordance with PCWG3, with progression dated as of the first “new lesion” scan.
!
For subsequent scheduled reassessments, new lesions will define the subject as disease 
progression in accordance with PCWG3, with progression dated as of the scan. 
PCWG3 Guidance for PSA
A PSA progression is defined as the time from start of therapy to first PSA increase that is ≥25% and 
≥2 ng/mL above the nadir, and which is confirmed by a second PSA value at least 4 weeks later (i.e., 
a confirmed rising trend).

Section 1.2
Rovalpituzumab 
Tesirine
Revised Paragraph 2:
In a Phase 1 study (Study SCRX16-001), rovalpituzumab tesirine 
dosed at 0.2 – 0.4 mg/kg exhibited encouraging efficacy in recurrent 
SCLC, achieving a 31% (8/26) and 85% (22/26) central review-
adjudicated confirmed objective response rate (ORR) and clinical 
benefit rate (CBR), respectively, in subjects whose tumors expressed 
DLL3 in ≥ 50% of cells.  Median overall survival was 7.7 months in 
DLL3 ≥ 50% subjects at all dose levels, with a 1-year survival rate of 
30%%. The most frequent grade 3 or worse treatment-related 
adverse events in 74 patients 
with small-cell lung cancer were thrombocytopenia (11%), pleural eff 
usion (8%), and increased lipase (7%). Drug-related serious adverse 
events occurred in 28 (38%) of 74 patients. The recommended phase 
2 dose and schedule is 0.3 mg/kg every 6 weeks.% (AbbVie 
Stemcentrx, data on file). A Phase 1 study with rovalpituzumab tesirine, 
SCRX16 001, has demonstrated encouraging results with an objective 
response rate (ORR) of 44% and a clinical benefit rate (CBR) of 78% in 
relapsed or refractory DLL3hi (delta like protein 3 positive in ≥50% 
tumor cells) SCLC subjects treated in the expansion cohorts of 0.2 mg/kg 
Q3wk (every 3 weeks) and 0.3 mg/kg Q6wk (every 6 weeks). In all 
expansion cohort SCLC subjects, regardless of DLL3 expression, the 
ORR and CBR were 23% and 66%, respectively (Stemcentrx data on 
file). Therefore, rovalpituzumab tesirine appears to be an active 
anticancer therapy.
New Paragraph 3:
In a Phase 2 SCRX001-002 (TRINITY) study in patients with SCLC 
recurrent after at least two systemic chemotherapy regimens, 
rovalpituzumab tesirine dosed at 0.3 mg/kg every 6 weeks for two 
cycles (with an option for additional two cycles upon progression 
occurring ≥ 12 weeks after the second dose) had shown confirmed 
objective response rate of 16%, progression-free survival of 3.9 
months and overall survival of 5.6 months in 3rd line DLL3High 
patients.  Of note, prolonged stable disease with target lesion size 
reduction has been observed in a considerable number of patients 
receiving additional post-progression cycles of rovalpituzumab 
Updated the 
section based on 
updated 
data/information 
now available.

tesirine. Drug related grade 3 or above treatment emergent adverse 
events that occurred in at least 10 subjects include thrombocytopenia 
(11%), photosensitivity reactions (7%), anemia (4%), fatigue (4%),

indirect sun exposure as much as possible during Rova-T treatment 
and for 30 days after the last dose. If unavoidable, patients should 
wear protective clothing and sunglasses, and use a broad-spectrum 
sunscreen and lip balm (SPF 30 or greater). 31 – 90 days after last 
dose, the patient may resume outdoor activities with appropriate sun 
protection including broad brimmed hat, protective clothing and 
sunscreen SPF 30 or higher. Skin reactions should be evaluated 
promptly and treated with topical or systemic steroids as indicated 
(refer to Table 5-2). Rova-T dose should be delayed, reduced or
discontinued as necessary (refer to Table 5-1).
Revised Paragraph 2:
All cutaneous reactions which develop during treatment warrant 
prompt evaluation. Skin toxicity with rovalpituzumab tesirine may 
consist of photosensitivity but possibly other reactions such as palmar-
plantar erythrodysesthesia or erythema multiforme. As such, development 
of a cutaneous reaction during treatment warrants prompt evaluation by 
the Investigator or designee:
Revised Bullets 1 and 2 :
• If clinically consistent with photosensitivity, the AE may should be 
reported as such (using medically accurate and descriptive AE 
terminology), and managed as described below in Table 5 2. 
• If notFor clinically more severe cases of photosensitivity or ifIf not  
clinically not consistent with photosensitivity, the following should be 
done, : PhotodocumentationPphotodocumentation to facilitate later 
review by the Sponsor or designee may occur.
Revised Sub Bullet 1:
• Formal evaluation by a dermatologist, including possible skin biopsy to 
rule out alternative etiologies, such as erythema multiforme which may 
warrant discontinuation of study drug, and to facilitate the most 
appropriate terminology for AE reporting, is recommended.

Tumor Tissue
Revised Paragraphs 1-2:
Tumor tissue, consisting of a representative archived specimen, or a fresh 
tumor biopsy, will be assessed at baseline for expression of DLL3 by 
methods such as but not necessarily limited to immunohistochemistry 
(Section 7.1.1). Additional studies, such as routine hematoxylin and eosin 
for morphology and histological classification, IHC for confirmation of 
diagnosis (e.g., for synaptophysin, chromogranin-A, or CD56 for 
neuroendocrine tumors, or HMB45, S100, or MART-1 for melanoma), or 
scoring of immune infiltrates (e.g., IHC for CD3+, CD4+, CD8+, and 
Foxp3+ cells) may be performed. Tumor material may also be utilized 
for exploratory research that includes assessments of nucleic acid or 
protein based biomarkers of drug sensitivity, resistance, or disease 
biology and development of a companion diagnostic assay. When 
fresh tumor biopsies are performed, tissue may also be collected for 
exploratory studies, such as but not necessarily limited to assays of drug 
sensitivity or resistance.
At PD, an optional tumor biopsy may be performed for the assessment of 
expression of DLL3 and/or execution of additional studies, such as but 
not necessarily limited to scoring of immune infiltrates or assessment of 
molecular pathways related to the response to rovalpituzumab tesirine. 
Tumor material may also be utilized for exploratory research that 
includes assessments of nucleic acid or protein based biomarkers of

Determination of 
Sample Size
In Part B, up to approximately 174 subjects may be enrolled, including 
approximately 19 subjects in each of the 56 disease-specific cohorts. The 
rationale for the sample size is based on the assumption that an ORR of 
around 15% would be indicative of efficacy worthy of further 
investigation given the advanced cancers and extensive treatment history 
in this study population. Additionally, an ORR below 5% would provide 
evidence of an ineffective treatment. The goal of the efficacy analyses is 
to provide a preliminary signal that the response rate may potentially be 
within that target range.
