Investigators:  
Multicenter
Study Sites:  
Approximately 65 globally
Study Population:  
Phase 1:  Histologically or cytologically confirmed extensive stage disease SCLC or any other 
advanced/metastatic solid tumor for which carboplatin/etoposide treatment is considered appropriate.
Phase 2:  Histologically or cytologically confirmed treatment-naïve extensive stage disease SCLC.
Number of Subjects to be Enrolled:  
Phase 1 Dose Escalation portion:  Approximately:  35
Phase 2 Randomized Double-Blind portion:  Approximately:  180
Methodology:
This is a Phase 1 dose escalation and Phase 2 randomized double-blind study.
Screening Procedures:
Screening procedures should be performed within 28 days of Cycle 1 Day –2.  If the screening visit is 
performed greater than 7 days prior to Cycle 1 Day –2, the physical exam, laboratory tests, and 
pregnancy test (for female subjects of childbearing potential) must be repeated on Cycle 1 Day –2.  Vital 
signs and performance status assessments will be performed on Cycle 1 Day –2 for all subjects.  
Baseline radiographic tumor assessments per computed tomography (CT) with IV contrast/magnetic 
resonance imaging (MRI) of the chest, abdomen, and pelvis will be conducted within 21 days prior to 
Cycle 1 Day –2.  If CNS metastases are suspected, a head CT must also be performed at screening.  If 
the subject is unable to undergo a CT scan with IV contrast due to allergy or renal insufficiency, a non-
contrast CT may be performed.  Magnetic resonance imaging (MRI) can be conducted in cases where 
local laws/requirements mandate, but should have Sponsor approval prior to performing the MRI.
Phase 1 Dose Escalation:
For subjects in the dose escalation portion of the study, each subject will participate in only 1 dose group 
and there is no provision for intra-subject dose-escalation.  Study procedures will be provided in the 
Schedule of Assessments and Pharmacokinetic and Pharmacodynamic tables.

Methodology (Continued):
Phase 1 Dose Escalation (Continued):
The Phase 1 portion of this study will evaluate the safety, tolerability, dose limiting toxicities (DLTs), 
RPTD, pharmacokinetics (PK), and pharmacodynamics (PD), of veliparib/carboplatin/etoposide 
combination in subjects diagnosed with Extensive Stage Disease Small Cell Lung Cancer or, other 
advanced/metastatic solid tumor for which carboplatin/etoposide treatment is considered appropriate.  
Veliparib will be administered on Days –2 to 5 (7-day schedule), and, if the MTD of the 7-day schedule 
is not reached at ≤ 200 mg BID veliparib dose level, may be administered on Days –2 to 12 (14-day 
schedule) and/or Days –2 to 19 (continuous schedule) orally BID, in combination with carboplatin area 
under the curve 5 mg/mL*min administered on Day 1 and etoposide 100 mg/m2 administered on Days 1 
to 3 via intravenous (IV) infusion in 21-day cycles.  An exception would be for the Phase 1 Cycle 2:  In 
the 7-day schedule, veliparib in Cycle 2 will be administered on Days 2 to 5 and for the 14-day schedule, 
Days 2 to 12 (veliparib dose on Cycle 2 Days –2 and –1 and Cycle 2 Day 1 will be omitted to allow for 
the evaluation of drug-drug interaction of veliparib with etoposide).
Upon completion of 4 cycles of combination therapy, subjects without evidence of disease progression 
will continue on veliparib 400 mg BID until disease progression or unacceptable toxicity.  Subjects who 
will be receiving prophylactic cranial irradiation (PCI) will have maintenance veliparib interrupted for 
the duration of radiotherapy.
All subjects will be monitored for DLTs during the DLT observation period (Cycle 1 Day –2 to pre-dose 
Cycle 2 Day 1), and treatment-related adverse events (AEs) will be evaluated throughout the course of 
the study for evidence of acute, delayed, or cumulative toxicities.
The dose levels of veliparib to be evaluated in the dose-escalation portion of this study were determined 
based on the outcome of prior clinical studies of veliparib as well as on pre-clinical toxicology, 
toxicokinetic, and nonclinical anti-tumor efficacy studies.  The following dose levels may be evaluated 
in the dose-escalation portion of the study:  80, 120, 160, 200, and 240 mg BID.  Reduced dose levels 
may be evaluated based upon review of subject safety and PK data.  Intermediate dose levels may be 
evaluated based upon review of subject safety including, but not limited to, Grade 2 study-drug related 
AEs.  If the MTD is not reached at veliparib 200 mg BID dose level, higher dose levels (with no more 
than 25% veliparib dose increments, and not exceeding single agent veliparib RPTD of 400 mg BID) 
may be evaluated at the discretion of the sponsor.  The alternative dosing schedules can include dosing 
veliparib Day –2 to 12 (14-day schedule) and/or Day –2 to 19 (continuous schedule) of 21 day Cycle.  
The initial dose for these schedules will be 200 mg BID or the maximum administered dose (MAD), not 
exceeding the MTD, in the 7-day schedule.  The 14-day schedule will be explored prior to continuous 
dosing schedule.  Reduced or interim dose levels may be evaluated based on review of the safety and 
PK.
A "3 + 3" escalation rule will be used for the dose-escalation portion of this study, with a condition 
applied for the Dose Level 1, which will allow 3 additional subjects to be entered in Dose Level 1 if 2 of 
6 initial subjects experience DLTs.  Enrollment of the 3 additional subjects at all dose levels will depend 
on a review of the specific DLTs observed and discussion with the Investigators.
Dose-Escalation Criteria:
AEs, clinical laboratory results, and vital signs will be assessed throughout the study in each 
dose-escalation cohort.

Methodology (Continued):
Dose-Escalation Criteria (Continued):
DLTs will be assessed in each dose-escalation cohort during the DLT observation period
(Cycle 1 Day –2 to pre-dose on Cycle 2 Day 1).  Based on the safety and tolerability of study drugs after 
the first cycle of treatment has been completed in at least 3 subjects, escalation to a subsequent dose 
level or expansion of the current dose level will occur based upon the following criteria:
Number of Subjects with 
DLT in the First Cycle
Escalation Decision Rule
0 out of 3
Enter 3 subjects at the next dose level.
1 out of 3
Add 3 more subjects at current dose level.  If AbbVie or the investigator 
considers the DLT(s) clinically significant, AbbVie will determine if it 
is appropriate to add more patients at this dose level.
!
If < 2 of 6 subjects (or < 33% of subjects) experience DLT, dose 
escalation will proceed to the next dose level.
!
If ≥ 2 of total 6 subjects (or ≥ 33% of subjects) experience DLTs, 
then dose escalation will be stopped.*
≥ 2 out of 3 or 6
Dose escalation will be stopped.  *Additional subjects will be enrolled 
at the previous lower dose level as needed.  The following exceptions 
apply to Dose Level 1:
!
If 2 of 6 initial subjects at Dose Level 1 experience DLTs, 
3 additional subjects may be entered and the cohort will be 
expanded up to 9 subjects for further DLT assessment.  
o
Enrollment of the 3 additional subjects will depend on a review 
of the specific DLTs observed and discussion with the 
Investigators.  
!
If 2 of 9 subjects at Dose Level 1 experience DLTs, then escalation 
to the next dose level may proceed.
!
If > 2 of 9 subjects in Dose Level 1 experience drug-related DLTs, 
dose-escalation will stop.
*
If 2 out of 6 subjects experience different DLTs, for example nausea and neutropenia, the data will be reviewed 
by the investigator and AbbVie to determine if 3 additional subjects should be added at that dose level.  If 
3 subjects will be added and none experience DLTs, this dose level will be declared the MTD.
An MTD and/or maximum administered dose (MAD), and RPTD, will be determined.  The MTD is 
defined as the maximum dose at which < 2 of 6 or ≤ 2 of 9 subjects experience a DLT during the DLT 
observation period.  The MAD is defined as the highest dose tested.  Both MAD and MTD may be 
determined independently for each tested dosing schedule of veliparib.  The RPTD and schedule will be 
determined based on the assessment of the observed toxicities, the MTD or MAD, and the overall safety 
profile of the study drug.  The RPTD cannot exceed the lower of MTD or MAD.  At the RPTD and 
schedule, additional subjects will be added as needed so that a total of at least 9 subjects will be treated 
at the RPTD during the dose escalation part of the study.

Methodology (Continued):
DLT Definition:
DLT is defined as any of the following drug-related toxicities occurring during the DLT observation 
period in any of the dose-escalation cohorts, with grading according to the National Cancer Institute 
(NCI) Common Toxicity Criteria for Adverse Events (CTCAE), Version 4.0:
1.
Cycle 1 events associated with treatment delay > 14 days in initiating Cycle 2:
a.
Grade 4 thrombocytopenia (platelets < 25.0 × 109/L)
b.
Grade 4 neutropenia (absolute neutrophil count (ANC) < 0.5 × 109/L)
c.
Grade 3 febrile neutropenia with fever lasting for > 7 days
d.
Grade 4 febrile neutropenia of any duration
NOTE:  Delay of more than 14 days in initiating Cycle 2 due to factors not directly related to 
treatment-emergent toxicity will not be considered a DLT.
2.
Grade ≥ 3 non-hematologic toxicity that represents at least 2 grade increase from baseline and is 
attributed to veliparib treatment:
a.
Exclusion:  nausea and vomiting lasting ≤ 48 hours or inadequately treated
b.
Exclusion:  electrolyte abnormalities resolving within ≤ 24 hours
c.
Exclusion:  hypersensitivity reactions
d.
Exclusion:  alopecia
3.
Grade 2 non-hematologic toxicity that represents at least 2 grade increase from baseline, is 
attributed to veliparib treatment and requires a treatment delay of > 14 days in initiation of Cycle 2
4.
Any toxicity that represents at least 2 grade increase from baseline, is attributed to veliparib 
treatment and requires at least one of:
a.
Dose modification within Cycle 1
b.
Omission of carboplatin, > 1 daily etoposide dose, or > 30% veliparib doses in Cycle 1
Subjects experiencing DLT(s) during DLT observation period (Cycle 1 Day –2 to pre-dose Cycle 2 
Day 1) will require an interruption and possible discontinuation from further participation in the study.  
Veliparib may be reintroduced at a reduced dose, if the toxicity returns to ≤ Grade 1 or to baseline if 
Grade 2 at study entry.  All decisions regarding continued dosing for individual subjects who experience 
a DLT will be medically managed by the investigator in conjunction with the AbbVie TA MD.
Pharmacokinetics:
Pharmacokinetics of veliparib and etoposide will be assessed to determine the drug-drug interactions.  
Further pharmacokinetics of carboplatin will be assessed on Day 1 of Cycle 1.
Phase 2 Randomized Double-Blind
The veliparib dose and schedule for the Phase 2 was determined to be 240 mg BID on a 14 day schedule 
based on the analysis of Phase 1 data.
Approximately 180 total subjects with treatment-naïve ED SCLC will be enrolled at the 240 mg BID 
veliparib/placebo dose and 14 day schedule in the Phase 2 double-blinded portion of the study.  They 
will be randomized in a 1:1:1 ratio to one of three treatment arms: 
●
Arm A:  veliparib in combination with carboplatin/etoposide followed by veliparib 
monotherapy
●
Arm B:  veliparib in combination with carboplatin/etoposide followed by placebo monotherapy

Methodology (Continued):
Phase 2 Randomized Double-Blind (Continued)
!
Arm C:  placebo in combination with carboplatin/etoposide followed by placebo monotherapy
Subjects in all Phase 2 study arms will receive a minimum of 4 cycles of combination therapy unless 
disease progression or unacceptable toxicity warrants earlier discontinuation from the treatment.  
Additional 2 cycles of combination therapy (e.g., up to a total of 6 cycles) may be administered at the 
investigators discretion if subject status at the completion of initial 4 cycles warrants continued 
combination treatment and/or if local SOC guidelines require 6 cycles of platinum-based therapy.  In the 
combination cycles of Arms A and B, subjects will receive veliparib at 240 mg BID on a 14-day 
schedule, Arm C will receive matching placebo.  After completion of the chemotherapy combination 
cycles (at least 4), subjects without evidence of disease progression will receive veliparib at 400 mg BID 
continuous dosing (21-day cycles) (Arms A), or matching placebo (Arms B and C) as per treatment arm 
assignment, until disease progression or unacceptable toxicity occurs.  
Subjects who will be receiving prophylactic cranial irradiation (PCI) will have maintenance veliparib 
interrupted for the duration of radiotherapy.
Subject randomization for Phase 2 will be stratified by baseline LDH level (> ULN versus ≤ ULN), and 
gender.
Pharmacodynamics (Phase 1 Dose Escalation and Phase 2 Randomized Double-Blind):
Research to find biomarkers that may serve as surrogates for clinical endpoints in future veliparib studies 
or that may be predictive of veliparib activity will be conducted.  Serum, plasma, blood and tissue 
samples will be collected at designated time points throughout the study.
Tumor Assessments and Safety Follow-Up
Tumor assessments will be performed until radiographic disease progression.  Tumor assessment and 
assessment of response will occur every 6 weeks (± 1 week) from C1D-2 for the first 24 weeks (Phase 1) 
or 30 weeks (Phase 2), then every 9 weeks (± 1 week) thereafter.  Tumor response will be determined 
according to the Response Evaluation Criteria in Solid Tumors (RECIST), Version 1.1.  Subjects will 
continue on study until they meet defined discontinuation criteria.  When the investigator has determined 
that a subject should discontinue the study, a Final Visit will be conducted.  Subjects will have a 30-Day 
Follow-Up Visit following the last dose of study drugs or placebo (Phase 2, dependent on treatment 
arm).  If the subject begins another treatment regimen directly following protocol treatment and if a 
30-Day Follow-Up Visit is not possible, all adverse events ongoing as of the end of study must be 
followed to a satisfactory conclusion.

Reference Therapy:
Etoposide
Doses:
100 mg/m2
Mode of Administration:
Intravenous infusion
Duration of Treatment:
Subject will remain on study drug until disease progression or unacceptable toxicity. 
Criteria for Evaluation:
Efficacy:
Progression-free survival (PFS) will be derived according to disease progression (radiographic 
progression per RECIST version 1.1) or death.  Radiographic tumor assessments for response will be 
conducted by CT scanning at baseline, every 6 weeks from C1D-2 for the first 24 weeks (Phase 1) or 
30 weeks (Phase 2), then every 9 weeks until disease progression.
Objective response rate (ORR) will be derived per RECIST version 1.1.  Radiographic tumor 
assessments for response will be conducted by CT scanning at baseline, every 6 weeks from C1D-2 for 
the first 24 weeks (Phase 1) or 30 weeks (Phase 2), then every 9 weeks until disease progression.
Duration of overall response (DOR) will be derived according to disease progression (radiographic 
progression per RECIST version 1.1). 
Overall survival will be determined by the Investigator at assessments throughout therapy.  After the 
final visit, survival information will be collected via electronic data capture (EDC) at 2 month intervals 
(or as requested by sponsor to support data analysis).
ECOG performance status will be determined by the Investigator at each assessment.  
Pharmacokinetic:
Blood samples for pharmacokinetics of veliparib, carboplatin (Phase 1 Dose Escalation only) and 
etoposide (Phase 1 Dose Escalation only) will be collected at designated time points throughout the 
study.  Pharmacokinetics of veliparib and etoposide will be assessed to determine the drug-drug 
interactions.  In addition, pharmacokinetics of carboplatin will be determined.

16
Criteria for Evaluation (Continued):
Pharmacodynamic:
Research to find biomarkers that may be predictive of veliparib activity will be conducted.  Serum, 
plasma, blood and archived tissue samples will be collected at designated time points throughout the 
study.
Pharmacogenetic:
DNA samples may be analyzed for genetic factors contributing to the subject's response to veliparib, or 
other study treatment, in terms of pharmacokinetics, efficacy, tolerability and safety.
Safety:
Adverse events, laboratory profiles, physical examinations, vital signs and neurological assessments will 
be evaluated and recorded throughout the study.
Statistical Methods:
Efficacy:
The following end point will be analyzed using data obtained from subjects in Phase 1 and Phase 2 
separately:
Objective Response Rate
The proportion of subjects with objective response (CR or PR) as assessed by the investigator using 
RECIST 1.1 will be calculated for all dosed subjects.
The following end point will be analyzed using data obtained from subjects in Phase 2:
Progression-Free Survival
Progression-Free Survival will be defined as the number of days from the date of randomization to the 
date of earliest radiographic disease progression or death.  All disease progression will be included 
regardless whether the event occurred while the subject was taking study drug or had previously 
discontinued study drug.  If the subject does not experience disease progression or death, then the data 
will be censored at the date of the last radiographic disease assessment.
Overall Survival
Overall survival will be defined as the number of days from the date of randomization to the date of 
death.  For subjects who did not die, their data will be censored at the date of last study visit or the last 
known date to be alive, whichever is later.  
Duration of Overall Response
Duration of overall response will be defined as the number of days from the date of first response (CR or 
PR) to the earliest documentation of radiographic progressive disease.  If a subject is still responding, 
then the subject's data will be censored at the date of the subject's last available radiographic disease 
assessment.  For subjects who never experience response, the subject's data will not be included in the 
analysis.
Performance Status
Changes and/or percent changes from baseline will be summarized using descriptive statistics for each 
scheduled post-baseline visit and for the Final Visit for ECOG performance status.  Post-baseline 
measurements more than 30 days after the last dose of study drug will not be included.  Subjects that do 
not have a baseline measurement or do not have any post-baseline measurements will not be included.

Statistical Methods (Continued):
Pharmacokinetic:
Plasma concentrations of veliparib, etoposide, and carboplatin and pharmacokinetic parameter values 
will be tabulated for each subject and each dose level, and summary statistics will be computed for each 
sampling time and each parameter.
The effects of co-administration of veliparib on etoposide pharmacokinetics will be addressed by 
analyzing the Cycle 1 Day 1 (veliparib with carboplatin and etoposide) and Cycle 2 Day 1 (carboplatin 
and etoposide alone) etoposide pharmacokinetic variables, including Tmax, dose normalized Cmax and 
dose normalized AUC.
Pharmacodynamic:
Biomarker results will be tabulated for each subject and each regimen, and summary statistics will be 
computed for each sampling time and each parameter.  The relationship between biomarker status and 
clinical outcome or drug exposure may be examined.
Safety:
●
The safety of veliparib in combination with carboplatin/etoposide will be assessed by 
evaluating the study drugs exposure, adverse events, serious adverse events, all deaths, as well 
as changes in laboratory determinations and vital sign parameters.  Safety will be summarized 
per dose level using descriptive statistics for the dose escalation cohorts and per treatment arm 
in Phase 2.
●
RPTD was determined based on the rate of DLTs and overall tolerability of the combination of 
veliparib, carboplatin and etoposide with at least 9 subjects treated at the RPTD in Phase 1 and 
will be further evaluated in Phase 2.

Introduction
3.1
Small Cell Lung Cancer (SCLC)
Small cell lung cancer (SCLC) is a neuroendocrine carcinoma that exhibits aggressive 
behavior, rapid growth, and early spread to distant sites.  It constitutes approximately 15% 
of lung carcinomas.  SCLC is staged as limited or extensive stage disease (LD and ED 
SCLC, respectively).  LD SCLC is defined herein as a disease confined to the hemithorax 
of origin, with or without the involvement of regional lymph nodes, including ipsilateral 
and contralateral hilar, ipsilateral and contralateral mediastinal, and ipsilateral 
supraclavicular nodes.  ED SCLC is defined as all other SCLC.  At presentation, 60% to 
70% of SCLC cases in the United States are diagnosed as extensive-stage disease, for 
which at present there is no curative treatment.  There has been no significant 
improvement in the clinical outcome for subjects with ED SCLC in the last 2 decades, and 
it remains one of the most fatal cancers.  The National Comprehensive Cancer Network 
(NCCN) recommended management approach for ED SCLC is platinum-based doublet 
systemic chemotherapy, and platinum-etoposide is the most common regimen in the 
North America and Europe.  This regimen achieves a response rate of 50% to 70%, 
median survival of 9 – 11 months and median 5-year survival of less than 5%.1-3  While 
SCLC is very sensitive to frontline platinum based doublet chemotherapy, most patients 
relapse and die of their disease.  Previous strategy to improve the outcome of the disease 
was the use of high intensity chemotherapy which led to an improvement in the response 
rate; however this did not translate into survival benefit due to heightened toxicities.4-6  
The incorporation of novel targeted agents with excellent safety profile and limited 
additive toxicity in combination with standard chemotherapy agents as a strategy for 
improved efficacy has a great potential for improved clinical outcome in this disease.

Poly (ADP) Ribose Polymerase (PARP)
Poly (ADP) ribose polymerases (PARPs) are a family of enzymes that catalyze the 
addition of ADP-ribose to a variety of cellular molecules.  Several members of PARP 
family are involved in DNA damage repair, primarily through base excision repair 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
28
mechanism.7-9  Inactive PARPs 1 and 2 bind to damaged DNA, which leads to their 
auto-activation.  The resulting activated PARP then poly(ADP-ribosyl)ates many nuclear 
target proteins, including those that facilitate DNA repair of both single-stranded or 
double-stranded DNA breaks.  Thus, inhibition of PARP results in less efficient DNA 
repair following a DNA damaging insult.  Veliparib potently inhibits PARP-1 
and -2 enzymes at clinically relevant concentrations.
DNA-damaging agents, including cytotoxic chemotherapy and radiation therapy, remain a 
mainstay of treatment for advanced cancer.  Since cancer cells are genetically unstable, 
often exhibiting complex karyotypes that include large deletions, insertions, and 
unbalanced translocations of chromosomal fragment, these cells are more susceptible than 
normal tissues to cytotoxicity induced by DNA-damaging agents.8  Deficiencies in 
mismatch repair and homologous recombination render cells more dependent on PARP 
for DNA repair and, hence, are more prone to cytotoxicity induced by PARP inhibition.10  
In particular, tumor cells with BRCA1 or BRCA2 deficiencies are exquisitely sensitive to 
PARP inhibition, even in the absence of any other insults.11-14
Consistent with the observation that PARP activity may act as a resistance factor in some 
tumors, PARP inhibitors have been shown in preclinical models to sensitize tumors to a 
variety of DNA-damaging agents, including cross-linking chemotherapy agents such as 
carboplatin and ionizing radiation therapy.
3.3
Veliparib
Veliparib is a potent oral PARP inhibitor that delays the repair of DNA damage induced 
by chemotherapeutic agents, including alkylating agents, platinums, and topoisomerase 
inhibitors, and radiation.  Nonclinical efficacy with veliparib in combination with these 
agents has been demonstrated across an array of tumor types, including melanoma, 
glioma, prostate, breast, and colon.
A detailed discussion of the preclinical toxicology, metabolism, and pharmacology can be 
found in the Investigator's Brochure.15

3.3.1
Preclinical Studies and Toxicology
Veliparib is a novel small molecule that is a potent inhibitor of both PARP-1 and PARP-2 
with Ki's of 5 nM and 3 nM, respectively.  In cells under oxidative stress, veliparib 
inhibits the PARP induced formation of poly-(ADP-ribose) (PAR) with an EC50 of 
2.4 nM.
In cellular assays, veliparib increases sensitivity of tumor cells to DNA-damaging agents 
including platinum agents, irinotecan, cyclophosphamide, temozolomide (TMZ) and 
radiation.  In preclinical tumor models, veliparib enhances the anti-tumor efficacy of 
crosslinking agents (cisplatin, carboplatin), alkylating/methylating agents (TMZ, 
cyclophosphamide), topoisomerase inhibitors (irinotecan) and radiation.
Veliparib has been shown to enhance the efficacy of carboplatin in several xenograft 
tumor models.

The toxicological profile of veliparib has been evaluated in nonclinical general toxicity 
studies that included single-dose (rats and mice), repeat-dose (duration of up to 6 months 
in rats and up to 9 months in dog), reproductive (embryofetal development in rat and 
rabbit), genetic (Ames, in vitro cytogenetics, in vivo micronucleus), phototoxicity (in 
vitro photosensitivity) and juvenile rat toxicity studies.  Primary nonclinical findings 
included effects on the central nervous system (convulsions, tremors), hematopoietic 
system (bone marrow depletion), reproductive system (male germ cell depletion, female 
reproductive tract tissues degeneration), and lymphoid tissues (lymphocyte depletion), 
with lesser effects on the gastrointestinal tract (single-cell necrosis) and cardiovascular 
system (10% QTc interval prolongation).  All findings were dose-dependent and 
reversible or self-limited.  Veliparib was genotoxic (induced chromosomal aberrations in 
vitro and increased micronuclei formation in vivo) and was toxic to the developing fetus 
(increases in the incidence of fetal external/visceral/skeletal malformations/variations) in 
rats and rabbits.  Veliparib demonstrated no phototoxic potential in photosensitivity tests.
3.3.2
Veliparib Pharmacokinetics/Pharmacodynamics
In humans, at least 90% of the dose is absorbed after oral administration of veliparib.  
Veliparib is primarily cleared in the urine as intact parent drug (73% of administered 
dose), with a small fraction of clearance from metabolism.  Preliminary clinical 
pharmacokinetic (PK) data available from 6 studies indicate that exposure of veliparib is 
approximately dose proportional over 10 through 500 mg BID dose range.  The 
absorption of veliparib after oral dosing is rapid, and veliparib plasma concentrations peak 
at approximately 1 to 2 hours after dosing across dose levels.  The terminal half-life of 
veliparib is about 6 hours, with minimal accumulation following multiple BID dosing.  
Food does not have a significant effect on veliparib bioavailability.  
Veliparib is not a potent inhibitor, nor an inducer, of the major human cytochrome P450s 
(CYPs), suggesting a minimal potential for DDIs at the anticipated therapeutic 
concentrations.  In study subjects, there was no significant pharmacokinetic interaction 
between veliparib and TMZ, and preliminary results indicate the absence of DDI between 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
31
veliparib and carboplatin/gemcitabine, between veliparib and FOLFIRI, between veliparib 
and carboplatin/paclitaxel, or between veliparib and capecitabine/5-FU.
In Phase 0 Study A10-161, substantial inhibition of PARP activity was observed in tumor 
biopsies collected 3 to 6 hours after dosing in all 3 subjects who received a single dose of 
25 mg veliparib (92%, 95%, and 100%).  For subjects receiving 50 mg, PARP activity 
inhibition in tumor biopsies averaged 75% at 3 to 6 hours after dosing (N = 3) and 
averaged 74% at 24 hours after dosing (N = 3).  Therefore, both 25 mg and 50 mg 
veliparib doses were biologically active.
3.3.3
Veliparib Clinical Studies
Veliparib is being investigated in AbbVie-sponsored studies, in Investigator initiated 
studies (IIS), and in CTEP-sponsored studies.  In these studies, veliparib is administered 
as monotherapy, combined with a variety of chemotherapeutic agents, or combined with 
radiation therapy.
Summary preliminary or final efficacy data from AbbVie sponsored studies show that 
veliparib has activity in combination with temozolomide (TMZ), with radiotherapy, and 
with carboplatin + paclitaxel.17 Data from non-AbbVie sponsored studies show veliparib 
has activity as monotherapy for treatment of ovarian cancer18 and activity in combination 
with carboplatin + paclitaxel for treatment of early breast cancer.19   Veliparib is currently 
in Phase 2 and Phase 3 clinical development in combination with several DNA-damaging 
agents across a variety of cancer indications.
Several clinical studies explored combinations of veliparib with carboplatin-based 
combination chemotherapies and one study is evaluating cisplatin/etoposide/veliparib 
combination.
Phase 1 data from subjects treated with veliparib, carboplatin, and paclitaxel for advanced 
non-small cell lung cancer (NSCLC) are available from Cancer Therapy Evaluation 
Program (CTEP) Study 7967.20  Veliparib was given orally BID on Days 1 to 7 of each 
21-day cycle, and paclitaxel and carboplatin were administered on Day 3.  Two DLTs 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
32
(febrile neutropenia and hyponatremia) were observed in 2 of 7 evaluable subjects treated 
at the maximum tolerated dose of veliparib 120 mg BID, paclitaxel 200 mg/m2, and 
carboplatin AUC 6.  The most common AEs reported in this study were neutropenia and 
fatigue (reported in > 50% of subjects); nausea, thrombocytopenia, and peripheral sensory 
neuropathy (> 40% of subjects); and anemia, constipation, alopecia, diarrhea, decreased 
appetite, lymphopenia, and myalgia (> 20% of subjects).
A double-blind, randomized Phase 2 study (Study M10-898) of carboplatin and paclitaxel 
with veliparib or placebo for subjects with advanced NSCLC is complete.  Therapy was 
delivered for up to 6 cycles with carboplatin AUC 6 (IV) and paclitaxel 200 mg/m2 (IV) 
every 3 weeks plus veliparib/placebo 120 mg BID (PO) on 7 days around chemotherapy 
administration.  Seventy-six squamous NSCLC subjects were treated with veliparib 
combination.  All subjects have completed therapy.  Leukopenia was increased in 
frequency by < 15% for veliparib versus placebo-treated subjects, and neutropenia was 
increased in frequency by < 10% for veliparib versus placebo-treated subjects.  No other 
AE was increased by > 5%.  AEs led to reduction or discontinuation of backbone 
therapies at similar rates (± 3%) with or without veliparib.  The efficacy data are 
summarized in Investigator Brochure, version 9.
An ongoing ECOG study E2511 is a Phase 1 and randomized Phase 2 double-blind 
clinical study of cisplatin and etoposide in combination with veliparib or placebo as 
frontline therapy for ED SCLC.21 In the Phase 1 part of the study the maximum 
administered dose of veliparib in combination with 75 mg/m2 cisplatin and 100 mg/m2
etoposide was 100 mg BID.  This dose was selected as the recommended Phase 2 dose for 
the randomized part of the study, which is currently ongoing.  The Phase 1 part of the 
study enrolled 9 patients with ED SCLC.  Veliparib was well tolerated at the 60 mg dose 
(0 of 3 patients with DLT).  DLT was seen in 1 of 6 patients treated at the 100 mg dose 
(grade 5 cardiac failure; Takotsubo cardiomyopathy).  The same subject experienced G4 
respiratory failure prior to G5 cardiac failure.  The maximum administered dose of 
veliparib of 100 mg BID on D1-7 in combination with standard doses of cisplatin and 
etoposide was defined as the RPTD.  Other Grades 3 – 4 adverse events irrespective of 

Veliparib
M14-361 Protocol Amendment 5

33
attribution included:  neutropenia (6), leukopenia (5), nausea (3), thrombocytopenia (2), 
fatigue (2), hyponatremia (2), dehydration (1), febrile neutropenia (1), and diarrhea (1).  
Unconfirmed investigator-assessed efficacy outcome in 7 evaluable patients were stable 
disease in 2/7 (28.6%), partial response in 4/7 (57.1%) and complete response in 
1/7 (14.3%) patients.21
Overall, approximately 3,700 cancer patients have been exposed to veliparib in AbbVie 
and CTEP clinical trials with veliparib administered as monotherapy and as combination 
therapy to study subjects with various solid and hematological tumors.  Based upon 
mechanism of action, nonclinical, and clinical data, hematological cytopenias 
(thrombocytopenia, anemia, neutropenia, and lymphopenia) are toxicities that may result 
from veliparib therapy.  When veliparib is administered as single-agent therapy, these 
toxicities are predominantly Grade 1 or Grade 2 toxicities.  In combination with cytotoxic 
chemotherapy, Grade 3 or Grade 4 cytopenias may be observed.  These toxicities are 
commonly associated with cancer therapies, and standard clinical practices to manage 
these toxicities are well-established.
Nausea and vomiting have been commonly observed in clinical trials with veliparib, 
including in subjects receiving single-agent therapy with veliparib.  Most observed 
toxicities in subjects exposed to veliparib have been as expected with DNA-damaging 
agents and are manageable with routine oncology supportive care.  Potential risks of 
veliparib administration, identified mostly in preclinical studies or based on 
pharmacological mechanism, but not confirmed in clinical studies, are seizures, changes 
in testes/ovaries, and toxicity to the developing fetus.  A potential risk of secondary 
malignancies is theoretical based on veliparib's mechanism of action.15
3.4
Carboplatin and Etoposide
Carboplatin is a commonly used platinum compound that acts by binding to 
Deoxyribonucleic Acid (DNA) and interrupting cell division.  It is approved by the Food 
and Drug Administration (FDA) for the treatment of patients with ovarian cancer.  It is 
also used for the treatment of non-small cell lung cancer (NSCLC), small cell lung cancer 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
34
(SCLC), head and neck cancer, endometrial cancer, metastatic seminoma and more 
recently in breast cancer.  Carboplatin is eliminated by renal excretion.  The clearance is 
related to the glomerular filtration rate (GFR).  Therefore it is dosed based on the GFR 
and the target area under the concentration versus time curve (AUC).  The main side 
effect of carboplatin is myelosuppression.  Other toxicities include nausea, vomiting, renal 
and neurotoxicity.22,23
Etoposide, commonly known as VP-16, is a semi-synthetic derivative of podophyllotoxin.  
Etoposide in combination with other approved chemotherapeutic agents is FDA approved 
as first-line treatment in subjects with small cell lung cancer.  The predominant 
macromolecular effect of etoposide appears to be the induction of DNA strand breaks by 
an interaction with DNA-topoisomerase II or the formation of free radicals.  Its main 
effect appears to be at the G2 portion of the cell cycle in mammalian cells.  Hematologic 
toxicity (myelosuppression) is the most frequently observed toxicity of etoposide.  Other 
frequent toxicities include nausea and vomiting, anorexia and alopecia.24
Carboplatin in combination with etoposide (both IV and oral formulations) has been 
extensively tested in randomized clinical trials in SCLC as well as in other tumor 
types.24-27  Most frequently reported adverse events in subjects treated with carboplatin 
and etoposide combination were myelosuppression (leukopenia and thrombocytopenia), 
nausea, vomiting and alopecia.
The recommended dose of carboplatin for this combination is AUC of 5 – 6 mg/mL*min 
on Day 1 and the dose for etoposide 100 mg/m2 on Days 1 – 3 of 21-day cycles per 
NCCN 2014 guidelines for the treatment of ED SCLC.
3.5
Study Rationale
The proposed study has the potential to advance the management of SCLC if it results in 
improved clinical outcome as anticipated, based on preclinical evaluation.
DNA damaging agents constitute the mainstay of therapy for SCLC.  The combination of 
DNA damaging cytotoxic chemotherapy (e.g., cisplatin and etoposide) and a 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
35
pharmacologic inhibitor of DNA damage repair enzyme, poly (ADP) Ribose polymerase 
(PARP), may result in greater cytotoxicity and antitumor efficacy of the cytotoxic agents.  
It is postulated that enhanced efficacy may translate into improved disease progression 
without concomitant increased toxicity in subjects with extensive stage SCLC.
The in vitro and in vivo studies of veliparib and standard cytotoxic agents for SCLC 
including cisplatin, carboplatin and etoposide, discussed in the preceding sections provide 
specific supporting evidence for the clinical evaluation of veliparib as an agent that can 
further potentiate currently available therapies for the treatment of SCLC.  Similar 
strategies are currently in clinical translation for various types of cancer including 
melanoma, breast and ovarian cancers.4-6  This clinical protocol represents the 
first attempt to translate the same concept into the treatment of SCLC where DNA 
damage-inducing agents form the cornerstone of therapy.  If successful, the proposed trial 
is able to provide additional clinical proof for the biologic principle that DNA damage 
repair enzyme inhibition through pharmacological agents will enhance the efficacy of 
classic cytotoxic agents that act by inducing DNA damage.
A positive outcome in this Phase 2 evaluation, in conjunction with such outcome from 
ECOG E2511 study, will provide a strong rationale to conduct a large definitive 
registration study of veliparib in combination with platinums and etoposide in ED SCLC.
3.6
Differences Statement
This study is designed to evaluate the safety and tolerability of veliparib in combination 
with carboplatin and etoposide in subjects with small cell lung cancer or 
advanced/metastatic solid tumors.  This is the first study being conducted with this 
combination of treatment.  Previous early phase studies have been designed to test the 
safety and tolerability of veliparib as monotherapy or in combination with chemotherapy.
3.7
Benefits and Risks
The Phase 1 Dose Escalation portion of this study proposed to establish the recommended 
Phase 2 dose and veliparib schedule.  These were determined to be veliparib 240 mg BID 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
36
on Days –2 – 12 (14-Day schedule) in combination with carboplatin AUC 5 mg/ml*hr on 
Day 1 and etoposide 100 mg/m2 on Days 1 – 3 of 21-Day cycle.  The Phase 2 portion of 
this study proposes to evaluate clinical outcomes for subjects with ED SCLC treated with 
veliparib added to standard therapy with carboplatin and etoposide.  Preclinical data 
demonstrate that veliparib potentiates the anti-tumor activity of platinums, and that 
platinum sensitivity often correlates with the sensitivity to PARP inhibitors.  The current 
study, Study M14-361, is the first to test veliparib in combination with carboplatin and 
etoposide in human subjects.
Risks in this study include toxicity from the addition of veliparib to standard therapy.  
Preliminary safety data from several Phase 1 and Phase 2 studies indicate that veliparib is 
tolerated in combination with carboplatin and paclitaxel at doses of up to 120 – 200 mg 
BID, and with cisplatin and etoposide at the maximum tested dose of 100 mg BID.  
Standard clinical practices to manage the toxicity of carboplatin + etoposide are well 
established.  Toxicity will be closely monitored at all study visits.  Toxicities of veliparib 
expected to overlap with the toxicity of carboplatin + etoposide regimen include 
nausea/vomiting and myelosuppression.  Other potential risks of veliparib administration, 
identified in preclinical studies or based on pharmacological mechanism, but not 
confirmed in clinical studies must also be considered.  These risks include seizures, 
changes in testes/ovaries, toxicity to the developing fetus and secondary malignancies.  
Addition of veliparib resulted in no compromise to the delivery of carboplatin.  Drug-drug 
interaction with etoposide is not anticipated, but will be monitored.

Investigational Plan
5.1
Overall Study Design and Plan:  Description
This is a Phase 1, open-label, dose escalation/Phase 2 randomized double-blind study of 
veliparib in combination with carboplatin and etoposide and maintenance veliparib 
monotherapy.  Subjects in Phase 1 will be group sequentially assigned to the ascending 
dose levels of veliparib in combination with standard carboplatin/etoposide regimen based 
on the observed toxicities.  Subjects in Phase 2 will be randomized in a 1:1:1 ratio to 
carboplatin, etoposide, placebo followed by placebo maintenance, or carboplatin, 
etoposide, veliparib followed by either veliparib or placebo maintenance.  Approximately 
215 adult male or female subjects diagnosed with extensive stage disease SCLC or other 
advanced/metastatic solid tumors will be selected to participate in the study according to 
the inclusion/exclusion criteria.

39
The study was designed to enroll approximately 35 subjects in Phase 1 and approximately 
180 subjects in Phase 2 to meet scientific and regulatory objectives without enrolling an 
undue number of subjects in alignment with ethical considerations.  Possible dose levels
to be evaluated are as shown in Table 4.
Phase 1 Dose Escalation
The Phase 1 portion of this study will evaluate the safety, tolerability, dose limiting 
toxicities (DLTs), RPTD, pharmacokinetics (PK), and pharmacodynamics (PD) of 
veliparib in combination with carboplatin and etoposide in 21-day cycles in subjects with 
small cell lung cancer or advanced/metastatic solid tumors with possible schedules 
outlined in Table 1, Table 2 and Table 3.  For the Phase 1 subjects receiving 
non-continuous dosing, veliparib in Cycle 2 will be administered on Days 2 – 5 or Days 2 
– 12 dependent on the dosing schedule to allow for evaluation of drug-drug interaction of 
veliparib with etoposide (Table 2).  Details on drug administration and cycle schedules are 
described in Section 5.5.1.2.

Upon completion of 4 cycles of combination therapy, subjects without evidence of disease 
progression will continue on maintenance monotherapy veliparib 400 mg BID until 
disease progression or unacceptable toxicity.  Subjects who will be receiving prophylactic 
cranial irradiation (PCI) will have maintenance veliparib interrupted for the duration of 
radiotherapy as described in Section 5.2.3.2.
For subjects in the Phase 1 dose escalation portion of the study, each subject will 
participate in only 1 dose group and there is no provision for intra-subject dose-escalation. 
Study procedures are provided in the Schedule of Assessments and Pharmacokinetic and 
Pharmacodynamic tables (Section 5.3.1).
All subjects will be monitored for DLTs during DLT observation period (Cycle 1 Day –2 
to pre-dose on Cycle 2 Day 1), and treatment-related adverse events (AEs) will be 
evaluated throughout the course of the study for evidence of acute, delayed, or cumulative 
toxicities.

EudraCT 2014-001764-35
41
Subjects who do not complete the DLT observation period for reasons other than DLT 
(e.g., withdraw consent, non-compliance, etc.) will be replaced to ensure appropriate 
number of subjects are evaluated.
The dose levels of veliparib to be evaluated in the dose-escalation portion of this study 
were determined based on the outcome of prior clinical studies of veliparib as well as on 
pre-clinical toxicology, toxicokinetic, and nonclinical anti-tumor efficacy studies.  The 
following dose levels may be evaluated in the dose-escalation portion of the study:  80, 
120, 160, 200 and 240 mg BID (Table 4).  Reduced dose levels may be evaluated based 
upon review of subject safety and PK data.  Intermediate dose levels may be evaluated 
based upon review of subject safety including, but not limited to, Grade 2 study-drug 
related AEs.  If the MTD is not reached at veliparib 200 mg BID dose level, higher dose 
levels (with no more than 25% veliparib dose increments, and not exceeding single agent 
veliparib RPTD of 400 mg BID (Table 4, Levels V – VIII) or alternative veliparib dosing 
schedules may be evaluated at the discretion of the sponsor.  The alternative dosing 
schedules can include dosing veliparib for Day –2 to Day 12 (14-day schedule) and/or 
Day –2 to Day 19 (continuous schedule) of the 21 day cycle (Table 1, Table 2 and 
Table 3).  The initial dose for these schedules will be 200 mg BID or the maximum 
administered dose (MAD), not exceeding the MTD in the 7 day schedule.  The 14-day 
schedule will be explored prior to continuous dosing schedule.  Reduced or interim dose 
levels may be evaluated based on review of the safety and PK.

A "3 + 3" escalation rule will be used for the dose-escalation portion of this study, with a 
condition applied for the Dose Level 1, which will allow 3 additional subjects to be 
entered in Dose Level 1 if 2 of 6 initial subjects experience DLTs.  Enrollment of the 
3 additional subjects at all dose levels will depend on a review of the specific DLTs 
observed and discussion with the Investigators.
A minimum of 3 evaluable subjects will be enrolled at each dose level.  Additional 
eligible subjects may be enrolled at the current dose level at the discretion of the 
Investigators and the AbbVie TA MD.  The dose escalation decisions will be made 
following the completion of the DLT observation period for the evaluable subjects in the 
intended cohort size.  If a cohort is over-enrolled, reported toxicities in additional subjects 
will be taken into consideration.
Dose-Escalation Criteria: 
AEs, clinical laboratory results and vital signs will be assessed throughout the study in 
each dose-escalation cohort.  
DLTs will be assessed in each dose-escalation cohort during DLT observation period 
(Cycle 1 Day –2 to pre-dose Cycle 2 Day 1).  Based on the safety and tolerability of study 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
43
drugs after the first cycle of treatment has been completed in at least 3 subjects, escalation 
to a subsequent dose level or expansion of the current dose level will occur based upon 
the following criteria (Table 5):
Table 5.
Dose Escalation Guidelines
Number of Subjects with 
DLT in the First Cycle
Escalation Decision Rule
0 out of 3
Enter 3 subjects at the next dose level.
1 out of 3
Add 3 more subjects at current dose level.  If AbbVie or the investigator 
considers the DLT(s) is clinically significant, AbbVie will determine if it is 
appropriate to add more patients at this dose level.
●
If < 2 of 6 subjects (or < 33% of subjects) experience DLT, dose 
escalation will proceed to the next dose level.
●
If ≥ 2 of total 6 subjects (or ≥ 33% of subjects) experience DLTs, then 
dose escalation will be stopped.*
≥ 2 out of 3 or 6
Dose escalation will be stopped.  *Additional subjects will be enrolled at 
the previous lower dose level as needed.  The following exceptions apply 
to Dose Level 1:
●
If 2 of 6 initial subjects at Dose Level 1 experience DLTs, 3 additional 
subjects may be entered and the cohort will be expanded up to 
9 subjects for further DLT assessment.  
o
Enrollment of the 3 additional subjects will depend on a review of 
the specific DLTs observed and discussion with the Investigators.  
●
If 2 of 9 subjects at Dose Level 1 experience DLTs, then escalation to 
the next dose level may proceed.
●
If > 2 of 9 subjects in Dose Level 1 experience DLTs, dose-escalation 
will stop.
*
If 2 out of 6 subjects experience different DLTs, for example nausea and neutropenia, the data will be reviewed by 
the investigators and AbbVie to determine if 3 additional subjects should be added at that dose level.  If 3 subjects 
will be added and none experience DLTs, this dose level will be declared the MTD.
An MTD and/or maximum administered dose (MAD), and RPTD, will be determined.  
The MTD is defined as the maximum dose at which < 2 of 6 or ≤ 2 of 9 subjects 
experience a DLT during the DLT observational period C1D-2 to C2D1.  The MAD is 
defined as the highest dose tested.  Both MAD and MTD may be determined 
independently for each tested dosing schedule of veliparib.  The RPTD and schedule will 
be determined based on the assessment of the observed toxicities, the MTD or MAD, and 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
44
the overall safety profile of the study drug.  The RPTD cannot exceed the lower of the 
MTD or MAD.  At the RPTD and schedule additional subjects will be added as needed so 
that a total of at least 9 subjects will be treated at the RPTD.
DLT Definition:  DLT is defined as any of the following drug-related toxicities occurring 
during the DLT observation period (Cycle 1 Day –2 to Cycle 2 Day 1) in any of the 
dose-escalation cohorts, with grading according to the National Cancer Institute (NCI) 
Common Toxicity Criteria for Adverse Events (CTCAE), version 4.020:
1.
Cycle 1 events associated with treatment delay > 14 days in initiating Cycle 2 
chemotherapy:
a.
Grade 4 thrombocytopenia (platelets < 25.0 × 109/L)
b. Grade 4 neutropenia (absolute neutrophil count (ANC) < 0.5 × 109/L)
c.
Grade 3 febrile neutropenia with fever lasting for > 7 days
d. Grade 4 febrile neutropenia of any duration
NOTE:  Delay of more than 14 days in initiating Cycle 2 due to factors not directly 
related to treatment emergent toxicity will not be considered a DLT.
2.
Grade ≥ 3 non-hematologic toxicity that represents at least 2 grade increase from 
baseline and is attributed to veliparib treatment:
a.
Exclusion:  nausea and vomiting lasting ≤ 48 hours or inadequately treated
b. Exclusion:  electrolyte abnormalities resolving within ≤ 24 hours
c.
Exclusion:  hypersensitivity reactions
d. Exclusion:  alopecia
3.
Grade 2 non-hematologic toxicity that represents at least 2 grade increase from 
baseline, is attributed to veliparib treatment and requires a treatment delay of 
> 14 days in initiation of Cycle 2
4.
Any toxicity that represents at least 2 grade increase from baseline, is attributed to 
veliparib treatment and requires at least one of:

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
45
a.
Dose modification within Cycle 1
b. Omission of carboplatin, > 1 daily etoposide dose, or > 30% veliparib doses in 
Cycle 1
Subjects experiencing DLT(s) during the DLT observation period will require an 
interruption of study drugs and possible discontinuation from further participation in the 
study.  Veliparib may be reintroduced at a reduced dose, if the toxicity returns to 
≤Grade 1 or to baseline if Grade 2 at study entry.  All decisions regarding continued 
dosing for individual subjects experiencing a DLT will be medically managed by the 
investigator in conjunction with the AbbVie TA MD.
A subject will be considered evaluable for DLT if he/she has completed the DLT 
evaluation period with the assigned regimen (full dose carboplatin, at least two doses of 
etoposide, with ≥80% compliance of veliparib) or discontinued Cycle 1 due to a DLT.  
All cohort sizes and numbers of subjects in the Phase 1 dose escalation criteria section 
above refer to evaluable subjects.  Any subjects who discontinue from study prior to the 
completion of the DLT evaluation period for any reason other than a DLT will be 
replaced.
Phase 1 Pharmacokinetics
Pharmacokinetics of veliparib and etoposide will be assessed to determine the drug-drug 
interactions.  Further pharmacokinetics of carboplatin will be assessed on Day 1 of 
Cycle 1 (please reference Table 10 and Table 11.)
Transition from Phase 1 to Phase 2
Once the veliparib RPTD and schedule is determined, the veliparib RPTD and schedule 
will be communicated to all participating research sites prior to the start of enrollment into 
the Phase 2.  Subjects from the Phase 1 Dose Escalation portion are not eligible for 
enrollment into the Phase 2 portion, but may continue to receive veliparib, carboplatin and 
etoposide at the assigned dose and schedule as long as they tolerate the study drug, show 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
46
no evidence of disease progression, and do not meet any of the criteria for subject 
discontinuation (Section 5.4.1).
Phase 2 Randomized Double-Blind
The veliparib dose and schedule for the Phase 2 was determined to be 240 mg BID on a 
14 day schedule based on the analysis of Phase 1 data.
Approximately 180 total subjects with treatment-naïve ED SCLC will be enrolled at the 
240 mg BID veliparib/placebo dose and 14 day schedule in the Phase 2 double-blinded 
portion of the study.  They will be randomized in a 1:1:1 ratio to one of three treatment 
arms: 
Arm A:  veliparib 240 mg in combination with carboplatin/etoposide followed by 
veliparib 400 mg BID monotherapy
Arm B:  veliparib 240 mg in combination with carboplatin/etoposide followed by placebo 
monotherapy
Arm C:  placebo in combination with carboplatin/etoposide followed by placebo 
monotherapy
Subjects in all Phase 2 study arms will receive a minimum of 4 cycles of combination 
therapy unless disease progression or unacceptable toxicity warrants earlier 
discontinuation from the treatment.  Additional 2 cycles of combination therapy (e.g., up 
to a total of 6 cycles) may be administered at the investigators discretion if subject status 
at the completion of initial 4 cycles warrants continued combination treatment and/or if 
local SOC guidelines require 6 cycles of platinum-based therapy.  In the combination 
cycles of Arms A and B, subjects will receive veliparib at 240 mg BID on a 14-day 
schedule, Arm C will receive matching placebo.  After completion of the chemotherapy 
combination cycles (at least 4), subjects without evidence of disease progression will 
receive veliparib at 400 mg BID continuous dosing (21-day cycles) (Arms A), or 

Veliparib
M14-361 Protocol Amendment 5

47
matching placebo (Arms B and C) as per treatment arm assignment, until disease 
progression or unacceptable toxicity occurs (Figure 2).  
Subject randomization for Phase 2 will be stratified by baseline LDH level (> ULN versus 
≤ ULN), and gender.

reserve.
Phase 2 Randomized Double-Blind
Subjects in the Phase 2 portion of the study are not allowed to have any prior antitumor 
treatment for the disease under study.  For the purposes of this protocol, antitumor 
treatment is defined as systemic anticancer agents (cytotoxic chemotherapy, hormonal 
therapy, immunotherapy, biologic therapy), radiotherapy, and investigational anti-cancer 
agents.  For subjects in Phase 2, radiotherapy to a single lesion with the intent of symptom 
palliation (irradiated lesion will not be used as a target lesion for RECIST evaluations) is 
allowed, if completed at least 2 weeks prior to Cycle 1 Day –2.

5.2.3.2
Concomitant Therapy
The locally approved product label, institutional guidelines, local practice, or applicable 
Summary of Product Characterizations (SmPC) for carboplatin and etoposide should be 
referenced for any concomitant therapy guidelines.
Premedication:
The prophylactic antiemetics, including 5-HT3 antagonists, according to 
institution, National Comprehensive Cancer Network (NCCN), European 
Society for Medical Oncology (ESMO) or American Society of Clinical 
Oncology (ASCO) guidelines should be given, prior to administration of 
carboplatin and etoposide.  Prophylaxis with anti-emetics (e.g., 5-HT3 
antagonists such as ondansetron) is strongly recommended when initiating 
single agent veliparib/placebo maintenance monotherapy.
Anticancer Agents:
Other anticancer agents are not permitted during the treatment portion of the 
study.  All subjects will receive carboplatin + etoposide with veliparib/placebo 
at specified timepoints during the treatment portion of the study.  The locally 
approved carboplatin and etoposide product labels or SmPCs should be 
referenced to determine if there are any contraindications associated with 
concomitant medications (e.g., phenytoin, etc.).
Supportive Care:
Best supportive care and treatment will be given as appropriate to each subject 
(antiemetics, antibiotics, transfusions, nutritional support, palliative treatment 
for pain, bisphosphonates or denosumab) according to institutional or clinical 
practice guidelines (e.g., ASCO, ESMO, or NCCN).
Growth Factors:
Biologic response modifiers administered for erythropoiesis 
(e.g., erythropoietin, darbepoetin alpha) and colony stimulating factors 
(e.g., neulasta, G-CSF, GM CSF, etc.) may be administered according to 
institutional or clinical practice guidelines (e.g., ASCO, ESMO, or NCCN).  
Growth factors prophylaxis will not be allowed in Cycle 1 (Day –2 through 
Day 21) of the dose escalation cohorts.  Growth factors prophylaxis is 
acceptable in Phase 2.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
55
Radiation:
Prophylactic cranial irradiation (PCI) is allowed during the study in the 
Maintenance phase of treatment at Investigators discretion.  The dose of PCI 
should be 24 Gy in 8 fractions of 3 Gy each, or per local treatment standards.  
Veliparib or placebo maintenance monotherapy will be held starting 2 days prior 
to the initiation of radiation therapy, throughout the radiation therapy and for 
4 days following radiation therapy.  Palliative radiation to a non-target lesion 
with the intent of symptom control is allowed; non-progressing status of lesion 
to be irradiated must be documented prior to the procedure.  Radiation to non-
target lesions for other reasons will not be allowed during combination treatment 
cycles and generally will not be allowed during maintenance; exceptional 
circumstances that may arise during maintenance must be discussed with 
AbbVie TA MD and non-progressing status of such lesions using the same 
modality as study tumor assessments will have to be documented prior to
procedure.
Surgery:
If the subject requires surgery during the study, then this needs to be discussed 
with the AbbVie TA MD.
Alternate Therapy:
No traditional herbal anti-cancer medicine (e.g., Chinese, Asian, etc.) may be 
taken concurrently with veliparib (a 14-day washout period must be 
documented).
5.2.4

Study Activities Phase 1 Dose Escalation (Continued)
a.
Screening visit must be performed within 28 days of Cycle 1 Day–2.  If the screening visit is performed > 7 days prior to Cycle 1 Day –2 the physical exam, laboratory tests 
(hematology and chemistry) and pregnancy test must be repeated on Cycle 1 Day –2.  Tumor assessments must be performed within 21 Days of Cycle 1 Day –2.  The scanned 
areas will include chest and abdomen (with image of liver and adrenal glands) at all radiographic assessments and head CT at screening visit (if clinical suspicion of CNS 
metastases).
b.
The informed consent must be signed and dated prior to the initiation of any screening or study specific procedure is performed.
c.
A subject's medical history will be reviewed at each visit.  Any changes from baseline will be recorded on the adverse event eCRF.
d.
Height will be assessed at Screening only.
e.
A serum pregnancy test must be performed at Screening, a urine pregnancy test on Cycle 1 Day –2 prior to dosing if > 7 days since obtaining the serum pregnancy test for 
women of childbearing potential.  Pregnancy tests may be repeated at any time during the study at the discretion of the investigator.
f.
Hematology labs do not need to be repeated if screening is within 7 days of Cycle 1 Day –2.  A central laboratory will be used for the study; however, sites may use a certified 
local laboratory to collect a sample to dose the subject.
g.
Chemistry panels do not need to be repeated if screening is within 7 days of Cycle 1 Day –2.  A central laboratory will be used for the study; however, sites may use a 
certified local laboratory to collect a sample to dose the subject.
h.
Clinical progression will include, but not limited to an evaluation of worsening performance status due to progressive disease, requirement for non-palliative radiation 
therapy, chemotherapy or surgery due to progressive disease or death due to progressive disease.
i.
Tumor assessments will be performed until disease progression.  Tumor assessment and assessment of response will occur every 6 weeks (± 1 week) from C1D-2 for the 
first 24 weeks, then every 9 weeks (± 1 week) thereafter.  Tumor Assessments at the end of Cycle 4 should be performed 1 week prior to the conclusion of Cycle 4 with 
radiographic results determined and reported to ensure subjects eligibility prior to subject starting continuous monotherapy veliparib dosing at Cycle 5.  A tumor assessment 
will be performed at the Final Visit for subjects who discontinue the study for reasons other than radiographic progression and if no assessment has been performed within the 
last 4 weeks.  An unscheduled assessment should be obtained in such subjects if a Final Visit will not be conducted.  The scanned areas will include chest, abdomen and 
pelvis at all tumor assessments.  A head CT will be performed if there is clinical suspicion of CNS metastases.
j.
Etoposide on Days 1, 2 and 3 and carboplatin on Day 1 of Cycles 1 – 4 will be administered IV by site staff after veliparib administration (exception:  veliparib will not be 
administered on Cycle 2 Day 1 of non-continuous dosing schedules).  Etoposide will be given prior to carboplatin, unless institutional guidelines require inverse sequence of 
administration.  
k.
Starting at Cycle 5 Day 1 and all subsequent monotherapy cycles, veliparib will be dispensed on Day 1.  See Section 5.0.
l.
Pre-medication will be given as per institutional guidelines.

g.
Only for subjects with known history of HBV or HCV without prior evidence of active disease-free status and if HBsAg/HCV RNA status within 3 months of the study entry 
is unknown.
h.
If clinical disease progression is suspected, progression must be confirmed radiographically per RECIST 1.1.  Clinical disease progression will include, but will not be limited 
to worsening performance status due to progressive disease, requirement for non-palliative radiation therapy, alternative chemotherapy or surgery due to progressive disease.  
At the Final Visit, a clinical disease progression assessment is required only for subjects who discontinue the study for reasons other than progression (clinical or 
radiographic).
i.
Tumor assessment and assessment of response will occur every 6 weeks (± 1 week) from C1D-2 for the first 30 weeks, then every 9 weeks (± 1 week) thereafter.  A tumor 
assessment will be performed at the Final Visit for subjects who discontinue the study for reasons other than radiographic progression and if no assessment has been 
performed within the last 4 weeks.  An unscheduled assessment should be obtained in such subjects if a Final Visit will not be conducted.  Subjects in Post-Treatment Follow-
Up should continue to receive tumor assessments at the protocol defined time points until an event of radiographic progression. 
j.
Veliparib will be dosed orally at 240 mg BID and 14-day schedule for up to 6 cycles.  Veliparib will be administered after the pre medications on all days when given with 
chemotherapy.  Veliparib will be given approximately every 12 hours with a glass of water (approximately 240 mL).
k.
Pre-medication will be given as per institutional guidelines.
l.
Starting at Maintenance Day 1 and all subsequent monotherapy cycles, veliparib or placebo will be dosed orally at 400 mg BID and continuous (21-day) dosing schedule.

5.3.1.1
Study Procedures
Unless otherwise stated, the baseline measurement for any given variable will be defined 
as the last value obtained for the variable prior to the first dose of study drug.
The study procedures outlined in Table 7 and Table 8 are discussed in detail in this
section, with the exception of the monitoring of treatment compliance (discussed in 
Section 5.5.7) and adverse event information (discussed in Section 6.0).  All study data 
will be recorded on eCRFs with supporting source documentation.
Screening procedures should be performed within 28 days prior to Cycle 1 Day –2.  If the 
screening visit is performed greater than 7 days prior to Cycle 1 Day –2, the physical 
exam, laboratory tests, and pregnancy test (for female subjects of childbearing potential) 
must be repeated on Cycle 1 Day –2.  Vital signs and performance status assessments will 
be performed on Cycle 1 Day –2 for all subjects.  Baseline radiographic tumor 
assessments per computed tomography (CT) with IV contrast/magnetic resonance 
imaging (MRI) of the chest, abdomen, pelvis and head (if CNS metastases are suspected) 
will be conducted within 21 days prior to Cycle 1 Day –2.  If the subject is unable to 
undergo a CT scan with IV contrast due to allergy or renal insufficiency, a non-contrast 
CT may be performed.  Magnetic resonance imaging (MRI) can be conducted in cases 
where local laws/requirements mandate, but should have Sponsor approval prior to 
performing the MRI.
For procedures performed at Screening and repeated, the later procedure performed prior 
to dosing will serve as a baseline for clinical assessment.  Subsequent study procedures 
should be performed approximately within ± 1 day on days of IV infusion of carboplatin 
and etoposide and ± 2 days for all safety visits and first Maintenance visit.  Clinical 
laboratory tests can be performed up to 48 hours prior to dosing.  
Informed Consent
Signed informed consent will be obtained from the subject before any study procedures 
are undertaken or before any prohibited medications are withheld from the subject in 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
69
order to participate in this study.  A separate optional informed consent will be required 
for pharmacogenetic testing.  Details about how informed consent will be obtained and 
documented are provided in Section 9.3.
Subjects will be considered screen failures if the informed consent has been signed and a 
study specific procedure has been performed (e.g., central laboratories drawn), but subject 
does not enter into the study.  The reason for screen failure will be documented in the 
source and will be captured in the eCRF.
Medical History
A complete medical history, including alcohol, tobacco and nicotine-containing product 
use history, will be taken at Screening.  The medical history includes complete medical 
history, including documentation of any clinically significant medical condition; the 
presence and severity of any symptoms/conditions associated with SCLC; and detailed 
SCLC oncology history (histology, staging, date of diagnosis, tumor burden, metastatic 
sites, surgical history).
On Cycle 1 Day –2, any changes observed from the screening assessments, prior to 
dosing, will be recorded in the subject's medical history.  At each subsequent visit, the 
subject's medical history will be reviewed and any clinically significant changes from 
baseline will be recorded in the source documents and on the adverse event eCRF.
Physical Examination
A physical examination, including body weight, will be performed per Table 7 and 
Table 8.  Physical examination during combination cycles will include hearing assessment 
if required by carboplatin locally approved product label, local practice, or applicable 
SmPC.  If the Screening physical examination is performed within 7 days of Cycle 1 
Day –2, it is not required to repeat the exam on Cycle 1 Day –2 unless clinically indicated.  
The Cycle 1 Day 8 physical examination may be symptom directed.  Clinically significant 
changes from baseline will be documented in the source documentation and eCRFs as 
adverse events.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
70
Height will be measured at the Screening Visit only.  The subject will wear lightweight 
clothing and no shoes during weighing.
Vital Signs
Vital signs will be performed per Table 7 and Table 8.  Vital sign determinations include 
sitting blood pressure, heart rate and body temperature.  If possible, blood pressure and 
heart rate measurements should not immediately follow scheduled blood collections.
12-Lead Electrocardiogram (ECG)
A resting single ECG will be performed per as per Table 7 and Table 8.  A qualified 
physician will determine whether any findings outside of normal physiological variation 
are clinically significant (in consultation with a cardiologist if necessary).  The physician 
will document whether findings are clinically significant (CS) or not clinically significant 
(NCS) on the tracing and sign and date the tracing.  The original annotated ECG tracing 
along with a photocopy of the tracing containing the physician's assessment will be 
retained in the subject's records at the study site.
ECOG Performance Status
The ECOG performance status will be assessed per Table 7 and Table 8 as follows:
Grade
ECOG
0
Fully Active, able to carry on all pre-disease performance without 
restriction.
1
Restricted in physically strenuous activity but ambulatory and able to carry 
out work of a light or sedentary nature, e.g., light housework, office work.
2
Ambulatory and capable of all self-care but unable to carry out any work 
activities.  Up and about more than 50% of waking hours.
3
Capable of only limited self-care, confined to bed or chair more than 50% 
of waking hours.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
71
4
Completely disabled.  Cannot carry on any self-care.  Totally confined to 
bed or chair.
Documentation of Non-Childbearing Status or Pregnancy Test
For each female subject, the investigator will document non-childbearing status 
(surgically sterile or post-menopausal for at least 1 year) or potential childbearing status.  
Subjects with non-childbearing status do not require pregnancy tests.  For subjects of 
childbearing potential, a serum pregnancy test will be performed at Screening and the 
results must be available prior to the administration of the first dose of study drug on 
Cycle 1 Day –2.  A urine pregnancy test should also be performed prior to dosing on 
Cycle 1 Day –2 if > 7 days since obtaining Screening serum test results.  The test results 
must be reviewed and determined to be negative prior to dosing.  A positive urine 
pregnancy test will be confirmed with a serum pregnancy test.  Pregnancy tests may also 
be repeated at the discretion of the investigator at any time during the study.
Should a female study subject become pregnant or suspect she is pregnant while 
participating in this study, she should inform the treating investigator immediately 
(Section 6.7).
Hepatitis Screen
Subjects with history of hepatitis C (HCV) must be tested for HCV RNA at screening if 
no documented test result is available from within 3 months from the date of informed 
consent, and for Phase 2 if status within 3 months of the study entry is unknown.  Subjects 
with history of hepatitis B (HBV) must be tested for HBV surface antigen (HBsAg) at 
screening if no documented test result is available from within 3 months from the date of 
informed consent, and for Phase 2 if status within 3 months of the study entry is unknown.  
Testing will be performed by the sponsor-designated central laboratory.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
72
Clinical Laboratory Tests
Samples for chemistry, hematology and urinalysis will be collected per Table 7 (Phase 1) 
and Table 8 (Phase 2).  Specific laboratory assessments are outlined in Table 12.
All study samples will be shipped to the central laboratory, and central laboratory results 
will be used for data analysis.  A certified local laboratory may be used to perform 
laboratory analyses for immediate treatment decisions; however, split or concurrent 
samples must be drawn and sent to the central laboratory for analysis.  The central 
laboratory will provide instructions regarding the collection, processing and shipping of 
samples.
Sites will obtain the estimated creatinine clearance locally.
Qualified medical staff at the site will review, initial and date all local and central 
laboratory results.  Any laboratory value outside the reference range that is considered 
clinically significant by the Investigator will be followed as appropriate.  Clinically 
significant laboratory values will be recorded as adverse events if they meet the criteria as 
specified in Section 6.6.
For any laboratory test value outside the reference range that the investigator considers 
being clinically significant:
●
The investigator will follow the out-of-range value to a satisfactory clinical 
resolution.
●
A laboratory test value that requires a subject to be discontinued from the 
study or requires a subject to receive treatment will be recorded as an adverse 
event.
Study samples for central laboratory analysis may be performed within 48 hours of the 
scheduled day.  A qualified (e.g., certification or accreditation) local laboratory may be 
used to perform laboratory analyses for treatment decisions but this cannot replace the

Subjects with history of hepatitis C (HCV) must be tested for HCV RNA at screening if no documented test result 
is available from within 3 months from the date of informed consent.  Subjects with history of hepatitis B (HBV) 
must be tested for HBV surface antigen (HBsAg) at screening if no documented test result is available from within 
3 months from the date of informed consent.  If HBsAg/HCV RNA status is unknown it must be tested at screening 
for Phase 2 subjects.  Testing will be performed by the sponsor-designated central laboratory.
Tumor Assessments (Radiographic)
A CT scan with contrast will be used in the evaluation of tumor responses with RECIST 
version 1.1.  The scanned areas will include chest, abdomen and pelvis at all radiographic 
assessments, and head CT as warranted by clinical suspicion of CNS metastases.
If the subject is unable to undergo a CT scan with IV contrast due to allergy or renal 
insufficiency, a non-contrast CT may be performed.  Magnetic resonance imaging (MRI) 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
74
can be conducted in cases where local laws/requirements mandate but should have 
Sponsor approval prior to performing the MRI.
Subjects will continue to be monitored by the same methodology unless evidence of 
tumor metastasis warrants otherwise.
Sites may be requested to electronically transfer copies of all CT or MRI scans used for 
radiographic tumor assessments in the Phase 2 part of the study to AbbVie.  Electronic 
copies of scans in DICOM format should be maintained at the sites until notification from 
AbbVie or end of study, whichever comes first.  Instructions regarding procedures for 
transferring scans will be provided separately, if the request for scans becomes necessary.
Tumor Assessments Schedule
Tumor assessments will be performed until radiographic disease progression.  Tumor 
assessment and assessment of response will occur every 6 weeks (± 1 week) from C1D-2 
for the first 24 weeks (Phase 1) or 30 weeks (Phase 2), then every 9 weeks (± 1 week) 
thereafter.  Tumor response will be determined according to the Response Evaluation 
Criteria in Solid Tumors (RECIST), Version 1.1.  Tumor assessment is to be performed at 
the Final Visit for subjects who discontinue the study for reasons other than radiographic 
progression and if no assessment has been performed within the last 4 weeks.  An 
unscheduled assessment should be obtained in such subjects if a Final Visit will not be 
conducted.
For Phase 2, the protocol defined tumor assessment schedule should be maintained 
independent of any treatment delays or changes.
Refer to Appendix C "RECIST (Version 1.1) for Tumor Response (PFS)" for response 
criteria and guidelines. 
Post-Treatment Follow-Up
Subjects who discontinue all study drugs prior to reaching an event of radiographic 
progression must enter into Post-Treatment Follow-Up.  Subjects will remain on study 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
75
(off study drug) and will continue to receive tumor assessments according to the protocol 
defined tumor assessment schedule until reaching an event of radiographic progression. 
Subjects who discontinue all study drugs due to toxicity should have a 30-day Follow-up 
visit prior to entering into Post-Treatment Follow-Up to ensure all toxicities have 
resolved.  Subjects will have a Final Visit and be discontinued from the study upon 
reaching an event of radiographic progression, if the Investigator determines they should 
be discontinued for any other reason or if the subject withdraws consent.
Survival Follow-Up (Phase 2 Only)
All discontinued subjects will have survival information collected via electronic data 
capture (EDC) at two month intervals (or as requested by sponsor to support data 
analysis) after the subject discontinues the study and continuing until the endpoint of 
death, the subject has become lost to follow-up, or AbbVie terminates the study.  
All subjects will be followed for survival information (i.e., the date and cause of death or 
last known alive date if not deceased) unless the subject requests to be withdrawn 
specifically from study survival follow-up; this request must be documented in the 
subject's medical record and signed by the Investigator.
If known, post treatment anti-cancer therapies, dates of initiation, and end dates will be 
collected.
If the subject withdraws from survival follow-up, the study staff may use a public 
information source (such as county records) to obtain information about survival status 
only, as appropriate per local regulations.
Randomization and Subject Number Assignment
An Interactive Response Technology System (IRT) will be utilized to register subjects.
The site will access the IRT system at Screening, after the subject signs informed consent 
and a unique subject number will be provided.  Subjects who complete all Screening 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
76
procedures and meet the eligibility criteria will proceed to dosing.  Subjects who sign 
consent and do not meet the eligibility criteria will be considered a screen failure and the 
reason for screen failure will be documented in the source and in the eCRF.  Subjects will 
also be registered as a screen failure in the IRT system.
Subjects in Phase 2 who complete all Screening procedures and meet the eligibility 
criteria will be randomized in a 1:1:1 ratio to one of three treatment arms:  
Arm A:  veliparib 240 mg in combination with carboplatin/etoposide followed by 
veliparib 400 mg BID monotherapy
Arm B:  veliparib 240 mg in combination with carboplatin/etoposide followed by placebo 
monotherapy
Arm C:  placebo in combination with carboplatin/etoposide followed by placebo 
monotherapy
A bottle number randomization schedule and a subject randomization schedule will be 
generated by the Data and Statistical Science Department at AbbVie prior to the start of 
the study.  A copy of all randomization schedules will be kept by the Data and Statistical 
Science Department at AbbVie and a copy will be forwarded to the IRT vendor.

Confinement
Subjects will not be confined in this study.
5.3.1.3
Meals and Dietary Requirements
There are no meal and dietary requirements for this study.
5.3.1.4
Blood Samples for Pharmacogenetic Analysis
One 4 mL whole blood sample for DNA isolation will be collected on Cycle 1 Day –2 
from each subject who consents to provide a sample for pharmacogenetic analysis. The 
procedure for obtaining and documenting informed consent is discussed in Section 9.3.  If 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
77
the sample is not collected on Cycle 1 Day –2, it may be collected at any time throughout 
the study.
The sample collection tubes will minimally be labeled with "PG-DNA," protocol number,
and subject number.  Samples will be shipped frozen to AbbVie or a designated laboratory 
for DNA extraction and long-term storage.  Instructions for the preparation and shipment 
of pharmacogenetic samples will be provided in the study specific laboratory manual.
If pharmacogenetic (PG) testing is performed, results from individual subjects will be kept 
coded and confidential and will not be given to anyone not directly involved with this 
research study.  AbbVie will store the DNA samples in a secure storage space with 
adequate measures to protect confidentiality.  Samples will be coded so that subject 
identities will not be available to the scientists conducting the genotyping analyses.  
Individual subject results will not be provided to the Investigator so that neither the 
subject nor the Investigator will have knowledge of specific subject genotypes.  AbbVie 
will keep the DNA samples until destroyed by AbbVie when this research is completed.  
These samples will not be stored longer than 20 years or per country requirement.
5.3.1.5
Collection and Handling of Pharmacodynamic Variables
Pharmacodynamic correlative studies are exploratory in nature.  Serum, plasma and tissue 
specimens may be utilized to evaluate known and novel markers (nucleic acids, 
peptides/proteins and/or metabolites) of disease status.  PD variables will be further 
discussed in Section 5.3.7.
Blood Collection for Plasma Markers
Twelve (12) mL (Cycle 1 Day –2 or Final Visit) or 6 mL (all other time points) of blood 
will be collected pre-dose by venipuncture at time points outlined in Table 9 in 
conjunction with PK samples, if possible.  The collection, processing and storage should 
be performed as described in the study specific laboratory manual.  The complete process 
of centrifugation, transfer to cryovial and freezing should be accomplished in less than 
1 hour from the time of blood draw.

formation, centrifugation, transfer to cryovials and freezing should be accomplished in 
less than 90 minutes from the time of blood draw.
Tissue Collection for IHC, ELISA and FISH DNA Mutational/Methylation Analysis
Archived Tissue Specimens:
Subjects must consent to provide available archived tissue for analysis.  It is recognized 
that samples suitable for analysis will not be available from all consenting subjects.  The 
most recent archived biopsy is preferred and should be obtained at Cycle 1 Day –2, if 
possible.  While sending FFPE blocks is preferred, slides prepared by the local pathology 
laboratory are acceptable and should be prepared as described in the study specific 
laboratory manual.  Study specific biopsies are not required for subject participation.

Collection of Samples for Analysis
Blood Samples for Veliparib Assay
Blood samples for veliparib assay will be collected by venipuncture at the designated time 
points outlined in Table 10 (Phase 1) and Table 11 (Phase 2).  The timing of blood 
collection is fundamental to the success of the study.  The timing of blood collections will 
take priority over all other scheduled study activities except for dosing.  The order of 
blood collections will be maintained to the minute such that the time intervals relative to 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
79
the preceding dose will be the same for all subjects.  The time that each blood sample is 
collected will be recorded to the minute.  
The date and time of the morning dose of veliparib on PK sampling day will be recorded.  
In Phase 2 portion, the date and time of the two doses of veliparib prior to PK sampling 
on C1D1, C2D1, C3D1 and C4D1 will also be recorded.
The collection, processing and storage should be performed as described in the study 
specific laboratory manual.
Approximately 7 blood samples are planned to be collected per subject in Phase 1 and 
6 samples per subject in Phase 2 for pharmacokinetic analysis.  The approximate number 
of blood samples planned for pharmacokinetic analysis is approximately 1325 for the 
entire study.
Blood Samples for Etoposide Assay
Blood samples for etoposide assay will be collected at the time points specified in 
Table 10.  The date and time of the dose of etoposide on PK sampling day will be 
recorded.  The collection, processing and storage should be performed as described in the 
study specific laboratory manual.  A total of 10 samples per subject will be collected for 
etoposide analysis in Phase 1 Cycles 1 and 2.  Blood samples for etoposide assay will not 
be collected for Phase 2 subjects.
Blood Samples for Unbound Carboplatin Assay 
Plasma concentration-time course of carboplatin will be determined on Cycle 1 Day 1.  
Blood samples will be collected at the time points outlined in Table 10.  The date and time 
of the dose of carboplatin on PK sampling day will be recorded.  The collection, 
processing and storage should be performed as described in the study specific laboratory 
manual.  A total of 3 samples per subject will be collected for carboplatin assay in Phase 1

5.3.2.2
Handling/Processing of Samples
The processing and storage of the PK samples for veliparib, carboplatin and etoposide 
should be performed as described in the study specific laboratory manual.
AbbVie or a designated laboratory will store the pharmacokinetic samples in a secure 
storage space with adequate measures to protect confidentiality.  To increase confidence 
in trends, remaining sample aliquots may be used to perform replicate tests, or sample 
analysis at additional time points for tests currently identified in the protocol.  The 
placebo samples may not be analyzed to confirm the absence of veliparib.  Upon 
completion of this research, AbbVie or a designated laboratory will destroy the samples.
5.3.2.3
Disposition of Samples
The frozen plasma samples for veliparib, carboplatin and etoposide assays will be packed 
in dry ice sufficient to last during transport and shipped from the study site to the central 
laboratory according to instructions in the central laboratory manual.
5.3.2.4
Measurement Methods
Analysis of Plasma Samples
Plasma concentrations of veliparib will be determined under the supervision of the Drug 
Analysis Department at AbbVie.  Placebo samples may or may not be analyzed to confirm 
the absence of veliparib (ABT-888).  Plasma concentrations of etoposide and carboplatin 
will be determined at external laboratories using validated assays under the supervision of 
the Drug Analysis Department at AbbVie.
5.3.3
Efficacy Variables
Efficacy variables are not primary endpoints in the Phase 1 Dose Escalation portion of the 
study.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
81
The primary efficacy endpoint in Phase 2 is progression free survival (PFS) from the time 
of subject randomization.  The secondary endpoints are objective response rate (ORR), 
overall survival (OS).  The tertiary endpoints are duration of response (DOR) and ECOG 
performance status. 
5.3.3.1
RECIST 1.1 for Tumor Response
Response criteria will be assessed using RECIST (Version 1.1).28 Changes in the 
measurable lesions over the course of therapy must be evaluated using the criteria 
presented in Appendix C.  Tumor assessments will be performed until disease 
progression.  See tumor assessment schedule in Section 5.3.1.1.
5.3.3.2
Definition of Disease Progression
Disease progression will be defined as radiographic progression of disease as determined 
by the investigator by RECIST (Version 1.1) Appendix C.
Clinical progression as determined by the investigator, which may be characterized as, but 
not limited to:
●
Increase in at least two points of ECOG performance status attributable to 
cancer progression;
●
Subject requires non-palliative radiation, chemotherapy or surgery due to 
progressive disease;
●
Death from progressive disease.
In cases where an Investigator determines that a subject has met the criteria for clinical 
disease progression, every effort should be made to confirm the progression 
radiographically.

5.3.4
Safety Variables
AbbVie will assess adverse events, laboratory data, ECGs and vital signs throughout the 
study.  Adverse events intensity and laboratory evaluation changes will be assessed by 
utilizing NCI CTCAE Version 4.0.21
During the conduct of the study, the AbbVie medical and safety team will be monitoring 
blinded, subject laboratory results and serious adverse event data as they are reported.
5.3.5
Pharmacokinetic Variables
Values for pharmacokinetic parameters of veliparib, including the maximum observed 
plasma concentration (Cmax), the time to Cmax (peak time, Tmax), the area under the plasma 
concentration-time curve from time 0 to time of last measurable concentration (AUCt) 
will be determined for veliparib doses on Day 1 of Cycle 1 using non-compartmental 
methods.
Values for pharmacokinetic parameters of etoposide including Cmax, AUC from time 0 to 
the last measurable concentration (AUCt) and from time 0 to time infinity (AUC∞), 
clearance and terminal half-life will be determined on Day 1 of Cycle 1 and Day 1 of 
Cycle 2 using noncompartmental methods.
Values for compartmental pharmacokinetic parameters of carboplatin in the dose 
escalation cohorts (such as volume of distribution and clearance) and of veliparib in the 
Phase 2 part of the study such as rate of absorption (Ka), apparent volume of distribution 
(V/F) and oral clearance (CL/F) may be estimated using a nonlinear mixed-effect 
population modeling approach with NONMEM software and reported in a separate 
pharmacokinetic report.
5.3.6
Pharmacogenetic Variables
DNA samples may be sequenced and data analyzed for genetic factors contributing to the 
disease or to the subject's response to veliparib, (or other study treatment) in terms of 
pharmacokinetics, efficacy, tolerability, and safety.  Such genetic factors may include 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
83
genes for drug metabolizing enzymes, drug transport proteins, genes within the target 
pathway, other genes believed to be related to the disease or to drug response.  Some 
genes currently insufficiently characterized or unknown may be understood to be 
important at the time of analysis.  The samples may be analyzed as part of a multi-study 
assessment of genetic factors involved in the response to veliparib, drugs of this class, or 
the disease state.  The samples may also be used for the development of diagnostic tests 
related to veliparib, drugs of this class, or the disease state.  The results of 
pharmacogenetic analyses will not be reported to subjects and may not be reported with 
the study summary.
5.3.7
Pharmacodynamic Variables
Several putative biomarkers of efficacy and response may be evaluated in this protocol 
with the goal of exploring the relationship between tumor response and/or disease status.
Biospecimens collected may be evaluated for genetic lesions whether they occur by 
amplification, chromosomal loss and/or mutational/methylation with the intent of 
identifying potential associations with subject outcome or to better characterize the 
disease.  These characterizations may be included, but are not limited, characterization of 
gene methylation/mutational status or copy number changes of genes, particularly those 
involved in DNA repair pathways.  Additional analysis aimed at identifying underlying 
defects in the homologous recombination pathway, regardless of etiology, may be 
performed and associated with response.
Biospecimens may be evaluated for levels of biomarkers including nucleic acids, 
proteins/peptides and metabolites.  For example, analysis of proteins, including but not 
limited to proteins involved in DNA repair, such as ERCC1 and XPF, may be performed 
on tumor tissue obtained from each consented subject and associated with response.
Samples collected during the course of this study may be banked and used in the future to 
investigate new scientific questions related to this study.  Additionally, the samples may 
be anonymized and used for diagnostic test development.  AbbVie (or a designated 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
84
laboratory) will store the samples in a secure storage space with adequate measures to 
protect confidentiality.  The samples will be retained while research on veliparib (or drugs 
of this class) continues for up to but no longer than 20 years.
5.4
Removal of Subjects from Therapy or Assessment
5.4.1
Discontinuation of Individual Subjects
Each subject has the right to withdraw from the study at any time.  In addition, the 
investigator may discontinue a subject from the study at any time if the investigator 
considers it necessary for any reason, including the occurrence of an adverse event or 
noncompliance with the protocol.  Subjects who withdraw or are discontinued from the 
study will not be replaced except as described in Section 5.1, unless it is mutually agreed 
upon, in writing, by the investigator and AbbVie.
When a subject discontinuation from the study (without reaching a protocol-defined 
endpoint) is planned, the Investigator is to notify the AbbVie TA MD or the clinical team 
representative (Section 7.0) via telephone as soon as possible (provided, in each case, 
subject care and safety are not compromised).  If not notified prior to discontinuation, the 
AbbVie TA MD may contact the site to discuss the reason for withdrawal from the study.
If a subject is discontinued from the study with an ongoing adverse event or an unresolved 
laboratory result that is significantly outside of the reference range, the investigator will 
attempt to provide follow-up until a satisfactory clinical resolution of the laboratory result 
or adverse event is achieved.
In the event that a positive result is obtained on a pregnancy test for a subject or a subject 
reports becoming pregnant during the study, the administration of study drug to that 
subject must be discontinued immediately.  The investigator must report a pregnancy 
within 1 working day of the site being aware to one of the AbbVie representatives listed 
in Section 6.6 or Section 7.0.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
85
Post-Treatment Follow-Up
Phase 2 subjects who discontinue treatment for reasons other than radiographic 
progression will be monitored in the Post-Treatment Follow-Up period of the study by the 
same imaging method (unless medical contraindication is noted) until disease progression 
(Table 8).
Final Visit
The visit at which an investigator identifies disease progression or at which a subject 
meets other criteria for study discontinuation will be considered the Final Visit.  The 
reason(s) for the discontinuation from the study will be recorded and assessments will be 
performed per Table 7 and Table 8.  It is preferable that Final Visit procedures be 
conducted prior to the initiation of another anticancer therapy.  However, these procedures 
should not interfere with the initiation of any new treatments or therapeutic modalities that 
the Investigator feels are necessary to treat the subject's condition.
30-Day Follow-Up Visit
Subjects who discontinue treatment for reasons other than radiographic progression will 
have a Follow-Up Visit approximately 30 days after the last dose of study drug and will 
transition to Post-Treatment Follow-Up. 
Subjects who discontinue treatment due to radiographic progression and have a Final Visit 
within 30 days of last dose of study drug will have one Follow-Up Visit approximately 
30 days after the last dose of study drug.
Survival Follow-Up
All discontinued subjects will have survival information collected via electronic data 
capture (EDC) at 2 month intervals (or as requested by sponsor to support data analysis) 
after the subject discontinues the study and continuing until the endpoint of death, the 
subject has become lost to follow-up, or AbbVie terminates the study.

5.4.1.1
Discontinuation of Combination and Maintenance Therapies 
in Phase 2
Subjects will receive veliparib, carboplatin and etoposide up to a maximum of 4 –
6 combination cycles or until reaching a protocol defined event of disease progression or 
experiencing unmanageable toxicity.  Dose reductions of carboplatin and etoposide will 
occur on the basis of the toxicity observed and may result in discontinuation of either 
agent.  The subject may continue on therapy with the remaining agent in combination with 
veliparib.  At the Investigator's discretion, carboplatin and/or etoposide administration 
may continue after veliparib has been discontinued.  Suitable subjects will receive 
veliparib/placebo maintenance monotherapy as per treatment arm assignment until 
reaching a protocol defined event of disease progression or experiencing unmanageable 
toxicity.
5.4.2
Discontinuation of Entire Study
AbbVie may terminate this study prematurely, either in its entirety or at any study site, for 
reasonable cause provided that written notice is submitted in advance of the intended 
termination.  The investigator may also terminate the study at his/her site for reasonable 
cause, after providing written notice to AbbVie in advance of the intended termination.  
Advance notice is not required by either party if the study is stopped due to safety 
concerns.  If AbbVie terminates the study for safety reasons, AbbVie will immediately 
notify the investigator by telephone and subsequently provide written instructions for 
study termination.
5.5

M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
88
5.5.1.1
Administration of Veliparib/Placebo
Subjects will self-administer the morning dose of veliparib/placebo and the evening doses 
of veliparib/placebo approximately 12 hours after the morning dose with or without food 
in the same calendar day.  Veliparib dose should be followed by a glass of water 
(approx. 240 mL).
It is recommended that if a subject misses a scheduled dose of veliparib/placebo and less 
than 6 hours have passed since the scheduled dosing time, the dose should be immediately 
taken.  It is recommended that if more than 6 hours have passed since the scheduled 
dosing time, the subject should not take the missed dose but should wait for the next 
regularly scheduled dose.
If the subject vomits within 15 minutes of taking veliparib, another dose is to be taken.  
The dose may only be repeated once.  If more than 15 minutes has passed from the time of 
oral dosing then no additional doses will be taken.  The subject is to contact the 
Investigator if additional veliparib is needed to complete BID dosing through the 
remainder of the cycle.
Subjects will be provided self-administration instructions and subject dosing cards to 
record the date and time the veliparib was administered.  Subjects will be instructed to 
store veliparib according to specific directions included in Table 15 in Section 5.5.2.3.  
Subjects should return bottles of veliparib (empty, partially filled or full) and the 
completed dosing card to the study site prior to each cycle and at the Final Visit.
5.5.1.2
Administration of Carboplatin and Etoposide
Carboplatin will be administered intravenously on Day 1 of every 21-day cycle.  
Etoposide will be administered intravenously on Days 1, 2 and 3 of every 21-day cycle.  
Carboplatin and Etoposide are to be given only after veliparib/placebo dosing on 
Cycle Day –2 and Day –1 are confirmed.  If veliparib/placebo was not taken by the 
subject on Day –2 and Day –1, a new supply of veliparib is to be dispensed, and Day –2 
and Day –1 are to be repeated for that cycle, if needed.  Etoposide will be administered

prior to carboplatin, unless institutional guidelines require inverse sequence of 
administration.  On the days of chemotherapy, veliparib will be administered after the 
premedications are given for etoposide, prior to the infusion of etoposide. 
Investigators should evaluate subjects for carboplatin and etoposide treatment per the 
locally approved product label, local practice, or applicable SmPC.  Carboplatin will be 
administered intravenously over approximately 30 minutes at AUC 5 mg/mL/min.  The 
dose of carboplatin will be calculated using the Calvert formula, with creatinine clearance 
calculated using the modified Cockroft-Gault equation, as specified in the Appendix E.
The maximum allowed doses of carboplatin are:
AUC5 = 750 mg
AUC4 = 600 mg
Etoposide will be administered intravenously over approximately 60 minutes at 
100 mg/m2.

5.5.3
Method of Assigning Subjects to Treatment Groups 
(Phase 1 Dose Escalation)
In the Phase 1 dose escalation portion of the study, there is no randomization schedule; 
however, an IRT system will still be utilized to assign subject numbers.  Subject numbers 
will be assigned by the IRT as subjects are enrolled in the study.
5.5.4
Method of Assigning Subjects to Treatment Groups 
(Phase 2 Randomized Double-Blind)
All subjects will be randomized using an IRT system.  Before the study is initiated, the 
IRT user manual, which provides instruction on how to use the system via the web or 
phone, will be provided to each site.
Subjects who complete all Screening procedures and meet eligibility criteria may proceed 
to randomization.  Subject randomization will be stratified by:  LDH (≤ ULN versus 
> ULN), and gender; therefore a subject's baseline LDH value must be known prior to 
randomization and when accessing the IRT to perform the randomization transaction.
The site will contact the IRT to obtain a Screening (subject) number once the subject has 
signed the informed consent and a study-specific procedure has been performed 
(i.e., central laboratory samples drawn).  Once the subject number is assigned, if the 
subject is not enrolled/randomized the reason for screen failure will be documented in the 
source document and in the eCRF.  If the subject meets all inclusion and none of the 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
93
exclusion criteria, the site will access the system to randomize the subject.  The IRT will 
randomize subjects in a 1:1:1 ratio to one of the three treatment arms as follows:
●
Arm A:  veliparib in combination with carboplatin/etoposide followed by 
veliparib monotherapy
●
Arm B:  veliparib in combination with carboplatin/etoposide followed by 
placebo monotherapy
●
Arm C:  placebo in combination with carboplatin/etoposide followed by 
placebo monotherapy
Subject randomization will be stratified by:  LDH (≤ ULN versus > ULN), and gender
5.5.5
Selection and Timing of Dose for Each Subject
Phase 1 Dose Escalation
All Phase 1 subjects will receive veliparib orally.  Depending on the dosing schedule 
assigned, veliparib will be dosed twice a day on Days –2 through 5 (7-day schedule) or 
Days –2 through 12 (14-day schedule) of 1st, 3rd and 4th 21-day cycles and on Days 2 
through 5 or Days 2 through 12 (14-day schedule) of the 2nd 21-day cycle, or on Days –2 
through 19 (continuous schedule) of the 21 day Cycles 1 – 4 at a dose level based on the 
dose escalation cohort assignment.  One dose will be taken in the morning and the second 
dose will be taken in the evening (approximately 12 hours after the morning dose).  The 
morning dose of veliparib should be administered in the clinic prior to etoposide and 
carboplatin, but after chemotherapy premedications on days when administered with 
chemotherapy.  Premedications may be administered per individual institutional 
standards.
After the end of Cycle 4, subjects without evidence of disease progression by radiographic 
assessment (CT) will receive veliparib at 400 mg BID continuous schedule 21 day cycle, 
until disease progression or unacceptable toxicity.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
94
A "3 + 3" escalation rule will be used for the Phase 1 dose escalation portion of this study, 
with a condition applied for the Dose Level 1, which will allow 3 additional subjects to be 
entered in Dose Level 1 if 2 of 6 initial subjects experience DLTs.  Enrollment of the 
3 additional subjects at all dose levels will depend on a review of the specific DLTs 
observed and discussion with the Investigators.  At the RPTD and schedule, additional 
subjects will be added as needed so that a total of at least 9 subjects will be treated at the 
RPTD.
Phase 2 Randomized Double-Blind
Subjects will complete at least 4 cycles of combination therapy, unless disease 
progression or unacceptable toxicity warrants earlier discontinuation from the 
combination treatment.  Subject whose status at the completion of the 4th cycle of 
combination therapy warrants, in the opinion of the investigator, continued combination 
treatment may receive up to two additional combination therapy cycles (e.g., up to a total 
of 6 cycles) if required by local standard of care.  After the completion of combination 
therapy, subjects without evidence of disease progression by most recent scheduled 
radiographic assessment (CT) will receive veliparib at 400 mg BID or placebo continuous 
schedule in 21-day cycles, until disease progression or unacceptable toxicity.
5.5.6
Blinding
All study site personnel, including the investigator, study coordinator, as well as the 
subjects, will remain blinded to the treatment throughout the course of the Phase 2 portion 
of the study.  The IRT system will provide access to blinded subject treatment information 
during the double-blind period, if needed.
AbbVie must be notified before breaking the blind, unless identification of the study drug 
is required for a medical emergency, i.e., situation in which the knowledge or the specific 
blinded treatment will affect the immediate management of the subject's conditions 
(e.g., antidote is available).  AbbVie must then be notified within 24 hours of the blind 
being broken.  The date and reason that the blind was broken must be recorded in the 
source documentation and on the CRF or eCRF, as applicable.

5.5.7
Treatment Compliance
The investigator or his/her designated and qualified representatives will 
administer/dispense study drug only to subjects enrolled in the study in accordance with 
the protocol.  The study drug must not be used for reasons other than that described in the 
protocol.  Veliparib/placebo should be taken as directed by the investigator.  Carboplatin 
and etoposide will be administered intravenously by trained site personnel.
Subjects will be instructed to return all veliparib/placebo bottles (empty, partially filled or 
full) and the completed dosing card to the study site personnel at each combination cycle 
Day 1, each Maintenance cycle Day 1, 30-Day Follow-Up Visit and/or at the Final Visit.  
The Investigator or his/her designated and qualified representatives will document the 
bottles returned and the number of capsules returned per bottle in the IRT system.
Upon completion or termination of the study, all original bottles/cartons containing 
unused veliparib/placebo (empty containers will be defaced and discarded on site) will be 
returned to AbbVie or the destruction facility according to AbbVie's instructions, or if 
pre-arranged between the sponsor and site, destruction of used and unused bottles will be 
performed at the site.
Subjects should be questioned regarding their adherence to the assigned treatment 
schedule at each study visit.  The Investigator or his/her designated and qualified 
representatives will also confirm that the subject took the required number of capsules per 
protocol. 
Unless otherwise directed by the investigator, a subject will be considered compliant with 
study drug, veliparib, if 80% of the assigned dose is taken during a cycle.  Compliance 
below 80% will require counseling of the subject by study site personnel.  The 
Investigator or his/her designated and qualified representatives will document compliance 
on the appropriate eCRF.

5.5.8
Drug Accountability
Upon receipt of a shipment of veliparib, the representative at each site will verify that 
study drug supplies are received intact and in the correct amounts.  This will be 
documented by signing and dating the Proof of Receipt (PoR) or similar document 
respectively via direct recording in the IRT.  The shipment receipt must be acknowledged 
in the IRT in order to become available for dispensation to subjects.  All veliparib/placebo 
must be retained in the designated secure area under proper storage conditions.  The study 
site will record the kit number of veliparib/placebo given to each subject in the source 
documents and on the eCRF.
The IRT will maintain a current and accurate inventory of study drug, accountability, 
reconciliation, returns, and destruction for each site.  The IRT will also include the lot 
number, the bottle/kit numbers, and the date veliparib/placebo was dispensed for each
subject.
In the event the IRT is not operable, the above information will be documented on forms 
provided/approved by the Sponsor.
The Investigator or designee will document the bottles of veliparib/placebo returned and 
the number of capsules on the appropriate form in the IRT.  If the number of capsules 
taken and the number of capsules returned do not add up to the number of capsules 
dispensed, an explanation is required and should be documented in the IRT.
An overall accountability of the study drug will be performed and verified by the AbbVie 
monitor throughout the study and at the site close-out visit.  All study drug unit doses 
must be inventoried, accounted for, and returned to the destruction facility or to AbbVie 
or destroyed per instructions from AbbVie and according to local regulations.  
The investigator and/or named the sub-investigators agree not to supply study medication 
to any persons not enrolled in the study.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
97
The site will record the dose of carboplatin and etoposide given to each subject in the 
source documents and on the eCRF.  As the investigator will obtain both carboplatin and 
etoposide commercially, site inventory and accountability of carboplatin and etoposide 
will not be performed, and drug accountability for carboplatin and etoposide will not be 
performed in the IRT.  However, each site will be responsible for tracking the lot numbers 
for all carboplatin and etoposide dispensed.
5.6
Discussion and Justification of Study Design
5.6.1
Discussion of Study Design and Choice of Control Groups
The carboplatin and etoposide combination chemotherapy is standard first-line treatment 
for ED SCLC.  Veliparib may have a potential benefit for subjects with ED SCLC.  This 
Phase 1 dose escalation/Phase 2 randomized double-blind study will determine the 
recommended Phase 2 dose of veliparib in combination with carboplatin and etoposide 
(Phase 1 portion), and will evaluate the treatment effect due to the addition of veliparib to 
carboplatin/etoposide chemotherapy followed by veliparib monotherapy maintenance in
subjects with ED SCLC (Phase 2 portion).
5.6.2
Appropriateness of Measurements
The Phase 1 dose escalation portion of the study is a standard 3 + 3 design.  Standard 
pharmacokinetic, statistical, clinical, and laboratory procedures will be utilized in this 
study.
The randomized double-blind Phase 2 portion will utilize a well-established surrogate ED 
SCLC and other solid tumor endpoint of progression free survival using RECIST 1.1 as a 
guideline for the measurement of responses in subjects with advanced or metastatic solid 
tumors.28  Secondary and tertiary endpoints of objective response rate, duration of overall 
response and overall survival of subjects receiving veliparib maintenance monotherapy 
will also be evaluated.

5.6.3
Suitability of Subject Population
Subjects with ED SCLC and advanced/metastatic solid tumors (Phase 1) and with 
treatment-naïve ED SCLC (Phase 2) and meeting inclusion and exclusion selection 
criteria as outlined in the Section 5.2.1 and Section 5.2.2 are appropriate for this study.  
Subjects with advanced/metastatic solid tumors will allow defining the recommended 
Phase 2 dose as the tolerability of the study regimen in this population should be similar 
to the target population with ED-SCLC.  Subjects with treatment-naïve ED SCLC are 
appropriate to define efficacy and safety of the study regimen since carboplatin/etoposide 
is the first line standard of care in this tumor type and SCLC is the intended indication for 
further clinical evaluation of veliparib/carboplatin/etoposide combination.
5.6.4
Selection of Doses in the Study
Phase 1 Dose Escalation
The initial starting dose of 80 mg BID veliparib in the Phase 1 portion of the study was 
derived from the results obtained in the ECOG E2511, GOG 9923 and AbbVie M10-898 
clinical studies, as well as from the non-clinical studies.  
Doses for carboplatin in combination with etoposide will be given as per standard of care 
in first line treatment for extensive stage SCLC as per NCCN guideline 2014.3
The dose for veliparib monotherapy is 400 mg BID. This dose is well characterized for 
safety and tolerability based on the experience from multiple clinical trials.  
Phase 2 Randomized Double-Blind
The RPTD has been defined in the Phase 1 portion of the study as veliparib 240 mg BID 
administered on Days –2 – 12 (14-Day schedule), carboplatin AUC 5 mg/ml*hr 
administered on Day 1, etoposide 100 mg/m2 administered on Days 1 – 3 of 21-Day 
cycles.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
99
The dose for veliparib/placebo monotherapy is 400 mg BID administered continuously in 
21-Day cycles.
5.7
Dose Reductions or Delays
If a subject experiences an adverse event that results in a delay in starting a cycle or 
requires that study regimen is delayed or interrupted during a cycle, the subject will 
complete the planned activities per Section 5.7.1 until resuming treatment.
Study drug interruptions for events that are clearly not related to the study drug treatment, 
(e.g., underlying cancer, planned surgical procedures or acute viral illnesses), should not 
necessitate a dose reduction.  The timing of dose resumption should be at the discretion of 
the Investigator.  Study treatment may be delayed for up to 21 days due to toxicity.  
Toxicity-related delays greater than 21 days will result in study treatment discontinuation.

the daily dose levels tested in the dose escalation part of the study.  The dose of each drug can be reduced 
independently based on the observed toxicities.  For veliparib dose level of 80 mg (Phase 1 only), Dose Reduction 
1 is to 60 mg, Dose Reduction 2 is to 40 mg.
5.7.1
Veliparib/Placebo Dose Reductions and Interruptions
The following are guidelines for dose reduction, interruption and discontinuation of 
veliparib/placebo during combination therapy:

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
100
1.
Veliparib/placebo will be discontinued if both carboplatin and etoposide are 
discontinued prior to the completion of the planned number of combination therapy 
cycles.
2.
For any subject who experiences Grade 3/4 toxicity which is not attributable to 
carboplatin/etoposide or the underlying disease, refer to Table 17 for dosing 
guidelines.
3.
Two dose reductions are prospectively allowed during combination therapy for 
subjects who experience toxicity attributable to veliparib/placebo.  Refer to 
Table 16 for dose reduction guidelines.
a.
Veliparib dose reduction at C1D1 is allowed in case of nausea and vomiting 
attributable to C1D-2 and C1D-1 veliparib doses
b. All veliparib/placebo dose reductions within combination therapy cycles are 
permanent.
c.
If further dose reductions (beyond prospectively allowed two) are required, 
sites must contact the AbbVie TA MD.
4.
Any ≥ Grade 2 event of seizure attributed to veliparib/placebo requires 
discontinuation of veliparib/placebo.
5.
Veliparib/placebo interruptions will not affect the schedule of planned study 
procedures and will not be replaced.  If veliparib/placebo-related toxicity 
necessitates the delay in veliparib/placebo re-initiation beyond the scheduled start 
of the next combination therapy cycle, the start of the cycle should be delayed until 
veliparib/placebo can be restarted.  The AbbVie TA MD may be contacted 
(Section 6.6) for subjects who require more than a 2-week delay in the re-initiation 
of the next cycle.
The following are guidelines for dose reduction, interruption and discontinuation of 
veliparib/placebo during Maintenance Therapy:
1.
Dose Reduction 1:  300 mg BID.

Veliparib

5.7.2
Carboplatin/Etoposide Dose Reductions and Delays
If a subject experiences an adverse event attributable to carboplatin or etoposide, 
carboplatin or etoposide may either be interrupted or the dose reduced.  
If a dose reduction or delay is required for carboplatin and/or etoposide, the Investigator 
should follow procedures as defined in the locally approved product label or applicable 
Summary of Product Characteristics (SmPC).  Section 5.7.2.1 outlines suggested dose 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
102
reductions for carboplatin/etoposide if above information is not available.  PD and/or PK 
samples will not be drawn during carboplatin and/or etoposide dose delays.
5.7.2.1
Guidelines for Carboplatin and Etoposide Dose Reductions 
and Delays
The below guidelines are suggested, unless described as mandatory.  If a dose reduction 
or delay is required for carboplatin and/or etoposide, the Investigator should follow 
procedures according to institutional guidelines, the locally approved product label, local 
practice, or applicable SmPC.  If the Investigator considers an event attributable to 
carboplatin and/or etoposide, the Investigator may consider reducing carboplatin and/or 
etoposide, but not veliparib/placebo.  Suggested guidelines for dose reduction, delay, and 
discontinuation are included in Table 16 and Table 19 (if locally approved product label, 
local standard of care guideline or applicable SmPC for carboplatin/etoposide 
combination chemotherapy are not available).
All carboplatin and/or etoposide dose reductions are permanent.  Re-escalation of the dose 
of therapy is not allowed.  All toxicities should have resolved to grade 1 or less prior to 
initiation of a new cycle of therapy, with the exception of anemia, alopecia, neuropathy, 
and non-treatment related clinically insignificant laboratory abnormalities.
If toxicity precludes the initiation of the dosing of carboplatin/etoposide in the cycle, and 
veliparib doses on Days –2 and –1 of the cycle have already been administered, veliparib 
should be administered again once the toxicity resolves for 2 days prior to 
carboplatin/etoposide dosing.  In such a case, a new supply of veliparib/placebo is to be 
dispensed, and Day –2 and Day –1 are to be repeated for that cycle.
For Phase 1 ONLY:  PD and/or PK samples will not be drawn during carboplatin and/or 
etoposide dose delays.  If the Investigator considers an event attributable to carboplatin 
and/or etoposide and not veliparib, the Investigator may consider reducing the dose of 
both agents.

5.7.2.1.1
Hematologic Toxicity
If chemotherapy must be withheld due to hematologic toxicity, CBC and platelet counts 
should be obtained weekly via central labs (if done locally, sample MUST be split for 
central lab) until the counts reach the lower limits for treatment as outlined.  The 
treatment schedule will then proceed in the usual sequence.
Neutropenia or Febrile Neutropenia
For febrile neutropenia with absolute neutrophil count (ANC) < 500/mm3 and a single 
temperature of > 38.3°C (101°F) or a sustained temperature of ≥38°C (100.4°F) for more 
than one hour, requiring intravenous antibiotics:
a.
Doses of both carboplatin and etoposide drugs should be reduced to the next lower 
dose level for all subsequent cycles of chemotherapy.  Suggested dose reduction 
levels are outlined in Table 14.
b. Implement dose reductions, as outlined in Table 19.
c.
Initiate prophylactic neutrophil growth factors (e.g., G-CSF) after the first episode 
and in accordance with local SOC practices, ASCO or NCCN guidelines.
d. If ANC counts do not recover within 3 weeks, discontinue all protocol therapy.
For treatment delays of more than 7 days due to neutropenia, carboplatin and etoposide 
should be dose-reduced to next lower dose level for all subsequent cycles of 
chemotherapy, as outlined in Table 19.
For nadir neutropenia in the absence of fever or with fever that is successfully treated by 
oral antibiotics, there will be no dose adjustment. 
ANC must be ≥ 1,500/mm3 on Day 1 of each cycle (mandatory).  If the ANC is lower 
than 1,500/mm3, then dosing of all drugs (carboplatin, etoposide and veliparib) will be 
delayed until recovery to the required ANC.

Veliparib
M14-361 Protocol Amendment 5

104
Platelets
For Grade 4 nadir platelet count decrease (thrombocytopenia) (platelets < 25,000 mm3), 
the dose of both carboplatin and etoposide should be reduced to next lower dose level 
from the previous dose for all subsequent cycles of chemotherapy.  Implement dose 
reductions 1 and 2 for the first and second episodes, respectively as outlined in Table 19.  
If counts do not recover within 3 weeks, discontinue all protocol therapy.
Platelet count must be > 100,000/mm3 on Day 1 of each cycle (mandatory).  Doses or all 
drugs (carboplatin, etoposide and veliparib) should be delayed until platelet count 
recovers to > 100,000/mm3.
Anemia
No dose reductions will be made for anemia.  Subjects should be supported per the 
treating physician's discretion.  The use of RBC transfusions for anemia will be allowed 
as clinically indicated and as per local standard of care or current NCCN guidelines.  The 
use of growth factors for anemia is not permitted during Phase 1 Cycle 1.
If more than two dose modifications of carboplatin and etoposide are required for 
hematologic toxicity, e.g., in cases where an additional dose modification is needed for a 
toxicity which was not observed earlier, please consult the AbbVie TA MD.
5.7.2.1.2
Non-Hematological Toxicity
Gastrointestinal Toxicity: Nausea and Vomiting
All subjects should receive antiemetics* to prevent nausea and vomiting.  Specific 
antiemetic therapy is left to the discretion of the treating physician (steroids and 5-HT3 
antagonists should be used).  For vomiting Grade ≥ 3, consider hospital admission and/or 
use of aprepitant, if possible.  Nausea/vomiting should have resolved to Grade 1 or less 
prior to initiation of next treatment cycle.  Do not modify carboplatin and/or etoposide 
doses due to nausea/vomiting.

*
Aprepitant, when given once daily for 14 days as a 100 mg capsule with an oral contraceptive containing 35 mcg of 
ethinyl estradiol and 1 mg of norethindrone, decreased the AUC of ethinyl estradiol by 43% and decreased the 
AUC of norethindrone by 8%.  Women of childbearing potential using pregnancy contraception that includes 
ethinyl estradiol should not receive Aprepitant for the treatment of nausea/delayed emesis.  Subjects may change to 
a different method of contraception if they wish to use Aprepitant.
Hepatic Toxicity
For bilirubin > 1.5 – 3.0 × ULN, not attributable to underlying disease, reduce the dose of 
etoposide to 50 mg/m2.  For bilirubin > 3 – 5 × ULN reduce the dose of etoposide to 
30 mg/m2.  For bilirubin > 5 × ULN hold etoposide or hold all treatment if starting the 
next treatment cycle.  When bilirubin resolves to ≤ 5 × ULN, treatment can be resumed, 
with etoposide dose to 30 mg/m2.  If bilirubin does not improve to ≤ 5 × ULN within 
3 weeks of first occurrence, discontinue protocol therapy.

Adverse Events
The investigator will monitor each subject for clinical and laboratory evidence of adverse 
events on a routine basis throughout the study.  The investigator will assess and record 
any adverse event in detail including the date of onset, event diagnosis (if known) or 
sign/symptom, severity, time course (end date, ongoing, intermittent), relationship of the 
adverse event to study drug, and any action(s) taken.  For serious adverse events 
considered as having "no reasonable possibility" of being associated with study drug, the 
investigator will provide another cause of the event.  For adverse events to be considered 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
107
intermittent, the events must be of similar nature and severity.  Adverse events, whether in 
response to a query, observed by site personnel, or reported spontaneously by the subject 
will be recorded.
All adverse events will be followed to a satisfactory conclusion.
6.1
Definitions
6.1.1
Adverse Event
An adverse event (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 adverse event 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 adverse event.  
Worsening in severity of a reported adverse event should be reported as a new adverse 
event.  Laboratory abnormalities and changes in vital signs are considered to be adverse 
events only if they result in discontinuation from the study, necessitate therapeutic 
medical intervention, (meets protocol specific criteria [see Section 6.8 regarding toxicity 
management]) and/or if the investigator considers them to be adverse events.
An elective surgery/procedure scheduled to occur during a study will not be considered an 
adverse event 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 is 
performed earlier than planned), then the deterioration of the condition for which the 
elective surgery/procedure is being done will be considered an adverse event.

6.1.2
Deaths
For this protocol, mortality is an efficacy endpoint.  Deaths that occur during the protocol 
specified adverse event reporting period (Section 6.5) that are attributed by the 
investigator solely to progression of disease under study should be recorded only on the 
Study Completion/Early Discontinuation eCRF.  All other on-study deaths, regardless of 
relationship to study drug, must be recorded on the Adverse Event eCRF and immediately 
reported to the Sponsor (Section 6.1.4).
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 Adverse Event 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 preexisting
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 Adverse Event eCRF.  If the cause of 
death later becomes available (e.g., after autopsy), "unexplained death" should be replaced 
by the established cause of death.
During survival follow-up, deaths should be recorded on Survival eCRF.
6.1.3
Lack of Efficacy or Worsening of Disease Under Study
Events that are clearly consistent with the expected pattern of progression of the 
underlying disease are also considered an expected outcome for this study and will be 
captured as adverse events, but will not be subject to expedited reporting.  These data will 
be captured as efficacy assessment data only.  Refer to Appendix F for listing of events 
expected with progression of ED SCLC.

6.1.4
Serious Adverse Events
If an adverse event meets any of the following criteria, it is to be reported to AbbVie as a 
serious adverse event (SAE) within 24 hours of the site being made aware of the serious 
adverse event:
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.
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).

EudraCT 2014-001764-35
110
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.
For serious adverse events with the outcome of death, the date and cause of death will be 
recorded on the appropriate case report form.
6.2
Adverse Events Expected Due to SCLC or Progression of 
SCLC
Adverse events that may be expected from primary SCLC lesions, compression of 
adjacent thoracic structures or distant metastases are presented in Appendix F of the 
protocol.
These adverse events may occur alone or in various combinations and are considered 
expected adverse events in SCLC subjects but will not be subject to expedited reporting.  
These data will be captured as efficacy assessment data only.
6.3
Adverse Event Severity
The investigator will rate the severity of each adverse event according to the National 
Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE 
Version 4.0).21

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
111
For adverse events not captured by the NCI CTCAE Version 4.0, the investigator will use 
the following definitions to rate the severity of each adverse event:
Mild 
(Grade 1)
The adverse event is transient and easily tolerated by the subject.
Moderate 
(Grade 2)
The adverse event causes the subject discomfort and interrupts the 
subject's usual activities.
Severe 
(Grade 3/4)
The adverse event causes considerable interference with the subject's 
usual activities and may be incapacitating or life-threatening.
Death 
(Grade 5)
Death
If a reported adverse event increases in severity, the initial adverse event should be given 
an outcome date and a new adverse event should be reported to reflect the change in 
severity.
For all reported serious adverse events that increase in severity, the SAE supplemental 
eCRFs also need to be updated and need to include the new AE serial number.
6.4
Relationship to Study Drug
The investigator will use the following definitions to assess the relationship of the adverse 
event 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.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
112
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.  For the purposes of this study, causality 
assessments will be attributed to veliparib/placebo or carboplatin or etoposide separately.
If an investigator's opinion of no reasonable possibility of being related to study drug is 
given, another cause of event must be provided by the investigator for the serious adverse 
event.
6.5
Adverse Event Collection Period
All protocol related serious adverse events and nonserious adverse events must be 
collected from the signing of the study specific informed consent until study drug 
administration.
In addition, all adverse events reported from the time of study drug administration until 
30 days following discontinuation of study drug administration have elapsed will be 
collected, whether solicited or spontaneously reported by the subject.
Serious and nonserious adverse events occurring after the study specific informed consent 
is signed but prior to the initial dose of study drugs will be collected only if they are 
considered by the Investigator to be causally related to the study-required procedures.
Adverse event information will be collected as shown in Figure 4.

Adverse Event Reporting
In the event of a serious adverse event, whether associated with study drug or not, the 
Investigator will notify  Clinical Pharmacovigilance within 24 hours of the site being 
made aware of the serious adverse event by entering the serious adverse event data into 
the electronic data capture (EDC) system.  Serious adverse events that occur prior to the 
site having access to the RAVE® system or if RAVE is not operable should be sent to 
Clinical Pharmacovigilance within 24 hours of being made aware of the serious adverse 
event using the paper CRF (pCRF).
Serious adverse events which are considered expected due to the underlying disease of 
SCLC would not be expedited as individual safety case reports to regulatory authorities.

(SUSAR) reporting for the Investigational Medicinal Product (IMP) in accordance with 
Directive 2001/20/EC.  The reference document used for SUSAR reporting in the EU 
countries will be the most current version of the Investigator's Brochure for veliparib or 
Summary of Product Characteristics (SmPC) for carboplatin and etoposide.
6.7
Pregnancy
In the event of a positive pregnancy test, subjects must immediately discontinue study 
drug and must be discontinued from the study.  The investigator must report the positive 
pregnancy test to the appropriate contact listed in protocol Section 6.6 within 1 working 
day of the site becoming aware of the pregnancy.
All subjects should be informed that contraceptive measures should be taken throughout 
the study and for 6 months after discontinuing study drug.  Information regarding a 
pregnancy occurrence in a study subject and the outcome of the pregnancy will be 
collected.  The Investigator must follow the pregnancy to completion and provide an 
update to AbbVie after delivery.
Male subjects should be informed that contraceptive measures should be taken by their 
female partners.  If the subject's partner should become pregnant during the study, this 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
116
should also be reported and data may be collected.  In the event of 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.
Pregnancy in a study subject is not considered an adverse event.  However, the medical 
outcome of an elective or spontaneous abortion, stillbirth or congenital anomaly is 
considered a serious adverse event and must be reported to AbbVie within 24 hours of the 
site becoming aware of the event.
6.8
Dose Limiting Toxicities
Dose limiting toxicities for Phase 1 dose escalation purposes will be determined during 
DLT observational period C1D-2 to pre-dose C2D1 in any of the dose-escalation cohorts, 
with grading according to the National Cancer Institute (NCI) Common Toxicity Criteria 
for Adverse Events (CTCAE), version 4.0.  Any of the events described in Section 5.1
considered to have a reasonable possibility of being related to veliparib will be considered 
a dose limiting toxicity (DLT).
Subjects experiencing DLTs during the DLT observational period C1D-2 to pre-dose 
C2D1 will generally be discontinued from further participation in the study, but may 
continue at the same or a reduced dose with written approval by the Sponsor if there is 
evidence of clinical benefit.
6.8.1
Determination of the MTD
If a single subject within a cohort experiences a DLT, a total of 6 subjects will be enrolled 
and dosed at the same dose level.  If these additional subjects do not exhibit a DLT, dose 
escalation may proceed.  If any of the additional subjects exhibits a dose limiting toxicity, 
then dose de-escalation may occur to interrogate lower dose levels.  MTD, if identified, 
will be defined at the highest dose level at which less than 2 of 6 subjects or < 33% of (if 
cohort is expanded beyond 6) subjects experience a DLT.  MTD may be determined 
independently for each veliparib dosing schedule.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
117
6.8.2
Determination of the RPTD
If an MTD is reached, the RPTD will not be a dose higher than the MTD and will be 
selected based on the types of DLTs which occur and the MTD identified.  If an MTD is 
not reached, then the RPTD will be defined based on the safety and available PK data.

Protocol Deviations
AbbVie does not allow intentional/prospective deviations from the protocol.  The 
principal investigator is responsible for complying with all protocol requirements, and 
applicable global and local laws regarding protocol deviations.  If a protocol deviation 
occurs (or is identified) after a subject has been enrolled, the principal investigator is 
responsible for notifying Independent Ethics Committee (IEC)/Independent Review 
Board (IRB) regulatory authorities (as applicable), and  Field Monitor or the following

Statistical and Analysis Plans
For subjects in the Phase 1 portion, the date of enrollment is defined as the first day of 
study drug administration.  For subjects in the randomized Phase 2 portion, the date of 
randomization (enrollment) is defined as the date that the IRT issued a subject number.
ORR will be performed on all dosed subjects in the Phase 1 portion of the study.
The primary, secondary, and tertiary efficacy analyses will be performed on all subjects in 
the randomized Phase 2 portion of the study.
Safety analyses will be performed separately for the Phase 1 and Phase 2 portions.  All 
subjects who receive at least one dose of the study drug will be included in the safety 
analysis.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
119
Unless otherwise noted, data will be summarized for Phase 1 and Phase 2 subjects 
separately.
8.1.1
Baseline Characteristics 
All baseline summary statistics and analyses will be based on characteristics obtained 
prior to the initiation of study drug (or randomization for non-treated subjects).  Unless 
otherwise stated, baseline for a given variable will be defined as the last value for that 
variable obtained prior to the first dose of study drug.
8.1.1.1
Demographics
Continuous demographic data (e.g., age, height, and weight) will be summarized with 
means, standard deviations, medians, and minimum and maximum values.  Frequencies 
and percentages will be computed for categorical data (e.g., sex, race, and performance 
status).
Smoking history can be defined as current smoker (subject who has smoked within the 
last 12 months and has more than 100 smoking events [for example, cigarettes] in their 
lifetime), never smoked (subject with a lifetime smoking history of ≤ 100 smoking events 
[for example, cigarettes] in lifetime) and past smoker (subject who has not smoked in past 
12 months and has more than 100 smoking events [for example, cigarettes] in their 
lifetime).
8.1.1.2
Medical History 
Frequencies and percentages will be computed for each medical history parameter.
8.1.2
Efficacy Endpoints
8.1.2.1
Primary Efficacy Endpoint
The primary efficacy endpoint is progression-free survival (PFS). 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
120
Progression-free survival will be defined as the number of days from the date of 
randomization to the date of earliest disease progression (radiographic progression per 
RECIST version 1.1) or death.  All events of disease progression will be included, 
regardless of whether the event occurred while the subject was still taking study drug or 
had previously discontinued study drug.  If the subject does not have an event of disease 
progression nor has the subject died, the subject's data will be censored at the date of the 
subject's last available radiographic disease progression assessment.
8.1.2.2
Secondary Efficacy Endpoints
Secondary efficacy endpoints include objective response rate and overall survival.
Objective Response Rate
The proportion of subjects with objective response (CR or PR) as assessed by the 
investigator using RECIST version 1.1 will be evaluated for randomized subjects.
Overall Survival
Overall survival will be defined as the number of days from the date of randomization to 
the date of death.  For subjects who did not die, their data will be censored at the date of 
last study visit or the last known date to be alive, whichever is later.
8.1.2.3
Tertiary Efficacy Endpoints
In addition to the primary and secondary efficacy analyses, tertiary efficacy analyses of 
duration of overall response and performance status will be performed.
Duration of Overall Response
Duration of overall response will be defined as the number of days from the date of 
first response (CR or PR) to the earliest documentation of radiographic progressive 
disease.  If a subject is still responding, then the subject's data will be censored at the date 
of the subject's last available disease assessment (radiographic or clinical).  For subjects 
who never experience response, the subject's data will not be included in the analysis.

and the corresponding 95% confidence interval will be obtained from a Cox proportional
hazards model.
8.1.5.4
ECOG Performance Status
Changes and/or percent changes from baseline in ECOG performance status will be 
summarized using descriptive statistics for each scheduled post-baseline visit and for the 
final visit.  Post-baseline measurements more than 30 days after the last dose of study 
drug will not be included.  Subjects that do not have a baseline measurement or do not 
have any post-baseline measurements will not be included.  Changes and/or percent 
changes from baseline to each visit will be compared between Arm A and Arm C as well 
as between Arm B and Arm C using an analysis of covariance with treatment arm as the 
factor and baseline value as a covariate.
8.1.6
Pharmacokinetics
8.1.6.1
Tabulations and Summary Statistics
Plasma concentrations and pharmacokinetic parameter values of veliparib, carboplatin, 
and etoposide will be tabulated for each subject by dose level, and summary statistics will 
be computed for each sampling time and each parameter by dose level.
8.1.6.2
Model and Tests
Dose Proportionality of Veliparib on Phase 1 Cycle 1 Day 1
To address the issue of dose proportionality for designated veliparib doses, a linear mixed 
effects model analysis will be performed for dose-normalized Cmax and AUC0-8 and other 
pharmacokinetic parameters provided that they can be adequately determined from the 
data.  The natural logarithmic transformation will be employed for Cmax and the AUC's 
unless the data clearly indicate that other transformation or the untransformed variable 
provides more nearly symmetric probability distributions and/or more nearly homogenous 
variances across dose levels.  The model will include dose level, this may be done by 
classifying subjects by dose level or, if appropriate, using dose level as a continuous

124
variable.  Some variables such as age, body weight, gender, and perhaps others that might 
explain some of the variability in the population will be included in the model initially as 
covariates.  A necessary condition for a variable to be included in the final model is that 
the regression coefficient be significant at level 0.10.  The dependence among explanatory 
variable candidates will also be considered when selecting the final model.
Within the framework of the final model, the null hypothesis of no difference between the 
means of the highest and lowest veliparib doses will be tested.  Assuming that at least 
four veliparib dose levels are indeed studied, a test will also be performed on a contrast in 
the dose level, with the contrast chosen to be sensitive to an approximately linear function
of dose or the logarithm of dose.
Veliparib Effect on Etoposide Pharmacokinetics Parameters
For the dose escalation subjects, a linear mixed effects model analysis will be performed 
for dose normalized Cmax, AUC0-24 and AUC∞, to compare etoposide pharmacokinetics 
parameters when co-administered with veliparib (Cycle 1 Day 1) relative to etoposide
administered alone (Cycle 2 Day 1).  For Cmax and AUC, the logarithmic transformation 
will be used unless the data indicate that the logarithm has significant non-normality.  The 
model will include effects for visit (Cycle 1 Day 1, Cycle 2 Day 1).  The within-subject 
variability will be accounted for utilizing the repeated statement for the effect of visit.  
Within the repeated measure analysis modeling framework, the null hypothesis of no 
difference between etoposide in combination with veliparib and etoposide alone will be 
tested with a significance level of 0.05.  The relative bioavailability of etoposide 
co-administered with veliparib relative to etoposide alone will be estimated.  Point 
estimates and corresponding 90% confidence intervals for the ratio of etoposide 
co-administered relative to etoposide alone will be provided.  The point estimates will be 
obtained by antilogarithm of the estimate of the difference of the logarithmic means.  The 
90% confidence intervals will be similarly obtained by antilogarithm of the endpoints of 
the corresponding confidence intervals for the difference of mean logarithms obtained 
within the framework of the repeated measure analysis model.

8.1.6.3
Missing Values and Model Violations
All available data will be included in the mixed effect analyses.  Data exclusion, if any, 
will be documented and justification provided.
Normally values of pharmacokinetic variables (Cmax, AUC, etc.) will be determined 
without replacing missing individual concentration values, simply using the available 
data, and if necessary doing the analysis with some missing values for a pharmacokinetic 
variable.  However, if a missing individual concentration results in a value of a 
pharmacokinetic parameter that may be too low or too high to a meaningful degree, the 
value of the pharmacokinetic parameter will tentatively be considered missing.  In this 
case, a value for the missing individual concentration may be imputed so that an 
appropriate value of the pharmacokinetic parameter can be included in the analysis.  The 
imputed value will be obtained using appropriate methodology that   takes into account 
the individual characteristics of the subject.
If an outlier is identified and/or a pronounced non-normal probability distribution is 
observed (after logarithmic transformation for Cmax and AUC), then a non-parametric 
analysis may also be performed.  Such a model violation may be identified by graphical 
methods, measures of non-normality (e.g., skewness, kurtosis) or other appropriate 
methods.  If the regimens have unequal variances to the extent that conclusions might be 
affected, then approximate methods that allow for unequal variances will be used.
8.1.7
Safety
Safety analyses will be performed for Phase 1 and Phase 2 separately.
8.1.7.1
Duration of Study Drug
A summary of the number of days and/or cycles subjects were exposed to study drug will 
be provided.

8.1.7.2
Adverse Events
Analyses of adverse events will include only "treatment-emergent" events, i.e., those that 
have an onset on or after the day of the first dose of study drug (veliparib or placebo).  
Analyses will not include those that have an onset greater than 30 days after the last dose 
of study drug.
Treatment-emergent adverse events will be coded and summarized by system organ class 
and preferred term according to the Medical Dictionary for Regulatory Activities 
(MedDRA) adverse event coding dictionary.  The percentage of subjects experiencing an 
adverse event at a given NCI CTCAE version 4.0 grade, and relationship to study drug 
will be provided.  For Phase 1, all summaries will be done by dose level.  For Phase 2, 
comparisons of the percentages of subjects experiencing an adverse event between Arm A 
and Arm C as well as between Arm B and Arm C will be performed using Fisher's exact 
test.
8.1.7.3
Serious Adverse Events
Serious adverse events will be summarized using the same methods as adverse events 
described above in Section 8.1.7.2.
8.1.7.4
Deaths
The number of subject deaths will be summarized 1) for deaths occurring while the 
subject was still receiving study drug in this study, 2) for deaths occurring off treatment 
within 30 days after the last dose of study drug, and 3) for all deaths in this study 
regardless of the number of days after the last dose of study drug.
8.1.7.5
Longitudinal Analyses of Laboratory and Vital Signs Data
Changes from baseline will be analyzed for each scheduled post-baseline visit and for the 
final visit for blood chemistry and hematology parameters, as well as urinalysis and vital 
sign parameters.  If more than one measurement exists for a subject on a particular day, an 
arithmetic average will be calculated.  This average will be considered to be that subject's 

Veliparib
M14-361 Protocol Amendment 5

measurement for that day.  Post-baseline measurements more than 30 days after the last 
dose of randomized study drug will not be included.  Subjects that do not have a baseline 
measurement or do not have any post-baseline measurements will not be included.  For 
Phase 1, changes from baseline will be analyzed by dose level at each scheduled visit.  
For Phase 2, comparisons of the differences in mean changes from baseline between 
Arm A and Arm C as well as between Arm B and Arm C will be made using ANCOVA 
with treatment group as the factor and baseline as a covariate.
8.1.7.6
Analyses of Laboratory Data Using NCI CTCAE
Where applicable, blood chemistry and hematology determinations will be categorized 
according to NCI CTCAE version 4.0 grades, and shifts from baseline NCI CTCAE 
version 4.0 grades to maximum and final post-baseline grades will be assessed.  The 
baseline and final grades will be defined respectively as the grade of the last measurement 
collected prior to the first dose of study drug, and as the grade of the last post-baseline 
measurement collected no more than 30 days after the last dose of study drug.  If multiple 
values are available for a post-baseline measurement, then the value with the highest NCI 
CTCAE grade will be used in the assessment of shift.  Comparisons of the number of 
subjects experiencing a shift from baseline grades of 0 to 2 or no grade to maximum 
post-baseline grades of 3 to 4, and from baseline grades of 0 to 2 or no grade to final 
post-baseline grades of 3 to 4 between Arm A and Arm C as well as between Arm B and 
Arm C will be performed using Fisher's exact tests.  Additional analyses including all 
measurements collected, regardless of the number of days after the last dose of study 
drug, will be performed.
Detailed listings of data for subjects experiencing NCI CTCAE Grade 3 to 4 blood 
chemistry and hematology values will be provided.  All measurements collected, 
regardless of the number of days after the last dose of study drug, will be included in these 
listings.

Analyses of Vital Signs Using Criteria for Potentially 
Clinically Significant Vital Sign Values
Detailed listings of data for subjects experiencing potentially clinically significant vital 
sign values according to the AbbVie-defined criteria for vital sign values will be provided.  
All measurements collected, regardless of the number of days after the last dose of study 
drug, will be included in these listings.
8.1.8
Timing of Efficacy Analyses and Safety Evaluations
When the 126th PFS event is observed, all efficacy and safety data as of this time will be 
retrieved and entered into the clinical database prior to breaking the study blind.  When 
the data collection is completed and reviewed for completeness and all data management 
quality assurance (QA) and quality control (QC) procedures are performed, the study 
blind will be broken and clinical database data will be extracted for documentation and 
statistical analyses of the efficacy and safety data.
Overall survival will be collected on all subjects.  After all survival data have been 
collected and entered into the clinical database, the clinical database will be extracted 
again for documentation and a "Final OS Analysis" will be performed on this dataset.
8.1.9
Data Monitoring Committee (DMC)
A safety DMC will be set up for the Phase 2 portion of the study to review the aggregate 
unblinded safety data.  The initial safety DMC review will occur once the first 30 Phase 2 
subjects complete combination treatment.  Based on this initial safety DMC review, the 
frequency of subsequent safety DMC reviews will be determined.  However, the initial 
safety DMC review may occur sooner:  if the observed rate of DLT-like events in the 
aggregate blinded safety review of the first 15 Phase 2 subjects exceeds the rate observed 
in the MTD/RPTD cohort by more than 10%, the safety DMC will convene immediately 
to review the aggregate unblinded safety data.  The details of the safety DMC setup and 
procedure will be outlined in a separate document.
The DMC will not evaluate efficacy data.

Determination of Sample Size
Phase 1 Dose Escalation
The number of subjects required for dose escalation portion will depend upon the 
toxicities observed as the trial progresses.
Phase 2 Randomized Double-Blind
Assuming a median PFS of 5.5 months for placebo in combination with carboplatin and 
etoposide followed by placebo monotherapy (Arm C) and a hazard ratio of 0.63 for 
veliparib in combination with carboplatin and etoposide followed by veliparib 
monotherapy (Arm A) versus Arm C, a total of 85 PFS events will provide an least 80% 
power to detect a statistically significant difference between Arm A and Arm C at a 
one-sided α = 0.1.  Further assuming a hazard ratio of 0.75 for veliparib in combination 
with carboplatin and etoposide followed by placebo monotherapy (Arm B) versus Arm C, 
a total of 126 PFS events will be observed across all three arms at the time when 85 PFS 
events are observed for Arm A and Arm C combined.  A total of approximately 
180 subjects (60 subjects per treatment arm) will be enrolled into the study to obtain the 
126 PFS events.
8.3
Randomization Methods
All subjects in the Phase 2 portion of the study will be randomized using an IRT system.  
Before the study is initiated, directions for the IRT will be provided to each site.  The site 
will contact the IRT to obtain a Screening (subject) number once the subject has signed 
the informed consent and a study-specific procedure has been performed (i.e., central 
laboratory samples drawn).  Once the Screening number is assigned, if the subject is not 
randomized into the study, the reason for screen failure will be documented in the source 
document and in the eCRF.  For others, the site will access the system and a unique 
randomization number will be provided.
The IRT will randomize subjects in a 1:1:1 ratio to one of the treatment arms as follows:

Veliparib
M14-361 Protocol Amendment 5

●
Arm B:  veliparib in combination with carboplatin/etoposide followed by 
placebo monotherapy
●
Arm C:  placebo in combination with carboplatin/etoposide followed by 
placebo monotherapy
Subject randomization will be stratified by baseline LDH (≤ ULN versus > ULN) and 
gender.  The stratification factors used for the randomization should be the last values on 
or prior to the date of randomization and should be consistent with those on the eCRF.
A bottle number randomization schedule and a subject randomization schedule will be 
generated by the Clinical Statistics Department at AbbVie prior to the start of the study.  
A copy of all randomization schedules will be kept by the Clinical Statistics Department 
at AbbVie and a copy will be forwarded to the IRT vendor.

RECIST (Version 1.1) for Tumor Response (PFS)
Response criteria will be assessed using RECIST (version 1.1).22  Changes in the 
measurable lesions over the course of therapy must be evaluated using the criteria listed 
below.
Eligibility
Subjects with measurable disease at baseline can have objective tumor response evaluated 
by RECIST (version 1.1).  Measurable disease is defined by the presence of at least 
one measurable lesion.  If the measurable disease is restricted to a solitary lesion, its 
neoplastic nature should be confirmed by cytology/histology if possible.
Measurability
Measurable 
Lesions
Lesions accurately measured in at least one dimension with a minimum size of:
●
Longest diameter ≥ 10 mm (CT scan slice thickness no greater than 5 mm)
●
10 mm caliper measurement by clinical exam
Non-Measurable 
Lesions
All other lesions, including small lesions (longest diameter < 10 mm) as well as 
truly non-measurable lesions.  Lesions considered truly non-measurable include:  
leptomeningeal disease, ascites, pleural/pericardial effusion, inflammatory breast 
disease, lymphangitic involvement of skin or lung and also abdominal masses that 
are not confirmed and followed by imaging techniques.
Measurable 
Malignant 
Lymph Nodes
To be considered pathologically enlarged and measurable, a lymph node must be 
≥15 mm in short axis when assessed by CT scan (CT scan slice thickness 
recommended to be no greater than 5 mm). At baseline and in follow-up, only the 
short axis will be measured and followed.
Non-Measurable 
Malignant 
Lymph Nodes
Pathological lymph nodes with ≥ 10 to < 15 mm short axis.

Special 
Considerations 
Regarding 
Lesion 
Measurability
Bone lesions
Lytic bone lesions or mixed lytic-blastic lesions, with identifiable soft tissue 
components, that can be evaluated by cross sectional imaging techniques such as 
MRI/CT can be considered as measurable lesions if the soft tissue component meets 
the definition of measurability described above.
Blastic bone lesions are non-measurable.
Cystic lesions
Lesions that meet the criteria for radiographically defined simple cysts should not 
be considered as malignant lesions (neither measurable nor non-measurable) since 
they are, by definition, simple cysts.
'Cystic lesions' thought to represent cystic metastases can be considered as 
measurable lesions, if they meet the definition of measurability described above.
However, if non-cystic lesions are present in the same patient, these are preferred 
for selection as target lesions.
Lesions with prior local treatment
Tumor lesions situated in a previously irradiated area, or in an area subjected to 
other loco-regional therapy, are usually not considered measurable unless there has 
been demonstrated progression in the lesion.
All measurements should be taken and recorded in metric notation, using calipers if 
clinically assessed.  All baseline evaluations should be performed as closely as possible to 
the beginning of treatment and not more than 21 days before the beginning of the 
treatment.
The same method of assessment and the same technique should be used to characterize 
each identified and reported lesion at baseline and during follow-up.
Clinical lesions will only be considered measurable when they are superficial (e.g., skin 
nodules and palpable lymph nodes) and ≥ 10 mm diameter as assessed using calipers.  For 
the case of skin lesions, documentation by color photography including a ruler to estimate 
the size of the lesion is recommended.
Methods of Measurement
Conventional CT with contrast should be performed with cuts of 5 mm or less in slice 
thickness contiguously.  This applies to tumors of the chest and abdomen.  A scale should 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
145
be incorporated into all radiographic measurements.  MRI can be performed if required by 
local law, but should have sponsor approval.
If prior to enrollment, it is known that a subject is not able to undergo CT scans with IV 
contrast due to allergy or renal insufficiency, the decision as to whether a non-contrast CT 
or MRI should be used to evaluate the subject at baseline and follow-up should be made.  
This decision should be guided by the tumor type under investigation and the anatomic 
location of the disease and the outcome of the decision should be communicated to 
AbbVie.  
For subjects who develop contraindications to contrast after baseline contrast CT is done, 
the decision as to whether non-contrast CT or MRI should be made based upon discussion 
with the AbbVie TA MD.
For accurate objective response evaluation, ultrasound (US) should not be used to 
measure tumor lesions.
The utilization of endoscopy and laparoscopy for objective tumor evaluation is not 
advised.  However, such techniques can be useful in confirming complete pathological 
response when biopsies are obtained.
Cytology and histology can be used to differentiate between partial response (PR) and 
complete response (CR) in rare cases.
Baseline Documentation of "Target" and "Non-Target" Lesions
All measurable lesions up to a maximum of 2 lesions per organ and 5 lesions in total, 
representative of all involved organs should be identified as target lesions and recorded 
and measured at baseline.  Target lesions should be selected on the basis of their size 
(lesions with the longest diameter), be representative of all involved organs, but in 
addition should be those that lend themselves to reproducible repeated measurements.  
Tumor lesions situated in a previously irradiated area, or in an area subjected to other 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
146
loco-regional therapy, are usually not considered measurable unless there has been 
demonstrated progression in the lesion.
Lymph nodes merit special mention since they are normal anatomical structures which 
may be visible by imaging even if not involved by tumor.  Pathological nodes which are 
defined as measurable and may be identified as target lesions must meet the criterion of a 
short axis of ≥ 15 mm by CT scan.  Only the short axis of these nodes will contribute to 
the baseline sum.  The short axis of the node is the diameter normally used by radiologists 
to judge if a node is involved by solid tumor.  Nodal size is normally reported as 
two dimensions in the plane in which the image is obtained (for CT scan this is almost 
always the axial plane).  The smaller of these measures is the short axis.  For example, an 
abdominal node which is reported as being 20 mm × 30 mm has a short axis of 20 mm 
and qualifies as a malignant, measurable node.  In this example, 20 mm should be 
recorded as the node measurement.  All other pathological nodes (those with short axis 
≥10 mm but < 15 mm) should be considered non-target lesions.  Nodes that have a short 
axis < 10 mm are considered non-pathological and should not be recorded or followed.
A sum of the longest diameter (LD) for all target lesions will be calculated and reported as 
the baseline sum LD.  If lymph nodes are to be included in the sum, then as noted above, 
only the short axis is added into the sum.  The baseline sum LD will be used as reference 
by which to characterize the objective tumor response.
All other lesions (or sites of disease) including pathological lymph nodes should be 
identified as non-target lesions and should also be recorded at baseline.  Measurements of 
these lesions are not required, but the presence (stable, increasing or decreasing) or 
absence of each should be noted throughout follow-up.
Evaluation of Target Lesions
Complete Response (CR):
The disappearance of all target lesions.  Any pathological lymph nodes (whether target or 
non-target) must have reduction in short axis to < 10 mm.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
147
Partial Response (PR):
At least a 30% decrease in the sum of diameters of target lesions, taking as reference the 
baseline sum diameters.
Progressive Disease (PD):
At least a 20% increase in the sum of the LD of target lesions, taking as reference the 
smallest sum LD recorded since the treatment started (baseline or after) or the appearance 
of one or more new lesions.  In addition to the relative increase of 20%, the sum must also 
demonstrate an absolute increase of at least 5 mm.
Stable Disease (SD):
Neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, 
taking as reference the smallest sum LD since the treatment started (baseline or after).
Assessment of Target Lesions:
Lymph nodes identified as target lesions should always have the actual short axis 
measurement recorded (measured in the same anatomical plane as the baseline 
examination), even if the nodes regress to below 10 mm on study.  This means that when 
lymph nodes are included as target lesions, the 'sum' of lesions may not be zero even if 
complete response criteria are met, since a normal lymph node is defined as having a short 
axis of < 10 mm.  For PR, SD and PD, the actual short axis measurement of the nodes is 
to be included in the sum of target lesions.
All lesions (nodal and non-nodal) recorded at baseline should have their actual 
measurements recorded at each subsequent evaluation, even when very small (< 5 mm).  
However, sometimes target lesions or lymph nodes become too small to measure.  If it is 
in the opinion of the radiologist that the lesion has likely disappeared, the measurement 
should be recorded as 0 mm.  If the lesion is believed to be present, but too small to 
measure, a default value of 5 mm should be assigned (as derived from the 5 mm CT slice 
thickness).  The measurement of these lesions is potentially non-reproducible; therefore 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
148
providing this default value will prevent false responses or progression based upon 
measurement error.
Evaluation of Non-Target Lesions
Complete Response (CR):
The disappearance of all non-target lesions and normalization of tumor marker level.  All 
lymph nodes must be non-pathological in size (< 10 mm short axis).
Non-CR/Non-PD:
Persistence of one or more non-target lesion(s) and/or maintenance of tumor marker level 
above the normal limits.
Progressive Disease (PD):
Unequivocal progression of existing non-target lesions.
In this setting, to achieve 'unequivocal progression' on the basis of non-target disease, 
there must be an overall level of substantial worsening in non-target disease such that, 
even in the presence of SD or PR in target disease, the overall tumor burden has increased 
sufficiently to merit discontinuation of therapy.  A modest 'increase' in the size of one or 
more non-target lesions is usually not sufficient to qualify for unequivocal progression 
status.  The designation of overall progression solely on the basis of change in non-target 
disease in the face of SD or PR of target disease will therefore be extremely rare.
New Lesions
The appearance of new malignant lesions denotes disease progression.  While there are no 
specific criteria for the identification of new radiographic lesions, the findings of a new 
lesion should be unequivocal; i.e., not attributable to differences in scanning technique, 
timing of scanning, phase of contrast administration, change in imaging modality or 
finding thought to represent something other than tumor (e.g., some 'new' bone lesions 
may be simply healing or flare of pre-existing lesions).  A lesion identified on a follow-up 

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
149
study in an anatomical location that was not scanned at baseline is considered a new 
lesion and will indicate disease progression.  An example of this is the patient who has 
visceral disease at baseline and while on study has a CT or MRI brain ordered which 
reveals metastases.  The patient's brain metastases are considered evidence of progressive 
disease even if he/she did not have brain imaging at baseline.
If a new lesion is equivocal (e.g., too small to measure), continued therapy and follow-up 
evaluation will clarify if it represents truly new disease.  If repeat scans confirm there is a 
new lesion, then progression should be declared using the date of the initial scan.

Calculation of Carboplatin Dose
The Cockcroft-Gault formula will be used.
The carboplatin dose will be calculated to reach a target AUC according to the Calvert 
formula using an estimated glomerular filtration rate (GFR) from the Cockcroft-Gault 
formula.
The initial dose of carboplatin must be calculated using GFR.  In the absence of renal 
toxicity greater than or equal to CTCAE Grade 2 (serum creatinine > 1.5 × ULN) or 
toxicity requiring dose modification, the dose of carboplatin will not need to be 
recalculated for subsequent cycles, but will be subject to dose modification for toxicity as 
noted in the protocol.
Carboplatin doses will be based on the subject's weight at baseline and will remain the 
same throughout the study.  However, the doses may be recalculated based on the 
subject's weight at each cycle, and need to be recalculated if the subject has a weight 
change of greater than or equal to 10% from baseline.
In subjects with an abnormally low serum creatinine (less than 0.7 mg/dL), the creatinine 
clearance should be estimated using a minimum value of 0.7 mg/dL.
CALVERT FORMULA:
Carboplatin dose (mg) = target AUC × (GFR + 25)
NOTE:  the GFR used in the Calvert formula should not exceed 125 mL/min.
Maximum carboplatin dose (mg) = target AUC (mg/ml × min) × 150 mL/min.
The maximum allowed doses of carboplatin are:
●
AUC5 = 750 mg
●
AUC4 = 600 mg

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
152
For the purposes of this protocol, the GFR is considered to be equivalent to the estimated 
creatinine clearance.  The estimated creatinine clearance (mL/min) is calculated by the 
method of Cockcroft-Gault using the following formula:
Creatinine Clearance (mL/min) = [140-Age (years)] × Weight (kg) × 
72 × serum creatinine (mg/dL)
For female subjects:  multiply the result above by 0.85.
Notes:
a.
Body mass index (BMI) should be calculated for each subject.  A BMI should be 
calculated using the following formula:
BMI = (Weight in kg) / (Height in meters)2
b. Actual weight should be used for estimation of GFR for subjects with BMI < 25.
c.
Adjusted weight should be used for estimation of GFR for subjects with BMI ≥ 25.
d. Adjusted weight calculation:
i. Ideal weight (kg) = (((Height (cm)/2.54) – 60) × 2.3) + 45.5
ii. Adjusted weight (kg) = ((Actual weight – Ideal weight) × 0.40) + 
Ideal weight
e.
If a patient with BMI of ≥ 25 is currently being dosed using actual weight, adjust 
dose with next planned treatment.
At the time of a dose modification for toxicity:
●
If the creatinine at the time of a dose modification is lower than the creatinine
used to calculate the previous dose, use the previous (higher) creatinine;
●
If the creatinine at the time of a dose modification is higher than the creatinine 
used to calculate the previous dose, use the current (higher) creatinine.  This 
will ensure that the patient is actually receiving a dose reduction.

Note that carboplatin dose will be recalculated if the subject has weight change of greater 
than or equal to 10% from baseline.

Methodology:
This is a Phase 1 dose escalation and Phase 2 randomized double-blind study.
Screening Procedures:
Screening procedures should be performed within 28 days of Cycle 1 Day –2.  If the screening visit is 
performed greater than 7 days prior to Cycle 1 Day –2, the physical exam, laboratory tests, and 
pregnancy test (for female subjects of childbearing potential) must be repeated on Cycle 1 Day –2.  Vital 
signs and performance status assessments will be performed on Cycle 1 Day –2 for all subjects.  
Baseline radiographic tumor assessments per computed tomography (CT)/magnetic resonance imaging 
(MRI) of the chest, abdomen, and head will be conducted within 21 days prior to Cycle 1 Day –2.  If 
CNS metastases are suspected, a head CT should also be performed at screening.
Phase 1 Dose Escalation:
For subjects in the dose escalation portion of the study, each subject will participate in only 1 dose group 
and there is no provision for intra-subject dose-escalation.  Study procedures will be provided in the 
Schedule of Assessments and Pharmacokinetic and Pharmacodynamic tables.
The Phase 1 portion of this study will evaluate the safety, tolerability, dose limiting toxicities (DLTs), 
RPTD, pharmacokinetics (PK), and pharmacodynamics (PD), of veliparib/carboplatin/etoposide 
combination in subjects diagnosed with Extensive Stage Disease Small Cell Lung Cancer or, other 
advanced/metastatic solid tumor for which carboplatin/etoposide treatment is considered appropriate.  
Veliparib will be administered on Days –2 to 5 (7-day schedule), and, if the MTD of the 7-day schedule 
is not reached at ≤ 200 mg BID veliparib dose level, may be administered on Days –2 to 12 (14-day 
schedule) and/or Days –2 to 19 (continuous schedule) orally BID, in combination with carboplatin area 
under the curve 5 mg/mL*min administered on Day 1 and etoposide 100 mg/m2 administered on Days 1 
to 3 via intravenous (IV) infusion in 21-day cycles.  An exception would be for the Phase 1 Cycle 2:  In 
the 7-day schedule, veliparib in Cycle 2 will be administered on Days 2 to 5 and for the 14-day schedule, 
Days 2 to 12 (veliparib dose on Cycle 2 Days –2 and –1 and Cycle 2 Day 1 will be omitted to allow for 
the evaluation of drug-drug interaction of veliparib with etoposide).
Upon completion of 4 cycles of combination therapy, subjects without evidence of disease progression 
will continue on veliparib 400 mg BID until disease progression or unacceptable toxicity.  Subjects who 
will be receiving prophylactic cranial irradiation (PCI) will have maintenance veliparib interrupted for 
the duration of radiotherapy.
All subjects will be monitored for DLTs during the DLT observation period (Cycle 1 Day –2 to pre-dose 
Cycle 2 Day 1), and treatment-related adverse events (AEs) will be evaluated throughout the course of 
the study for evidence of acute, delayed, or cumulative toxicities.
The dose levels of veliparib to be evaluated in the dose-escalation portion of this study were determined 
based on the outcome of prior clinical studies of veliparib as well as on pre-clinical toxicology, 
toxicokinetic, and nonclinical anti-tumor efficacy studies.  The following dose levels may be evaluated 
in the dose-escalation portion of the study:  80, 120, 160, 200, and 240 mg BID.  Reduced dose levels 
may be evaluated based upon review of subject safety and PK data.  Intermediate dose levels may be 
evaluated based upon review of subject safety including, but not limited to, Grade 2 study-drug related 
AEs.  If the MTD is not reached at veliparib 200 mg BID dose level, higher dose levels (with no more 
than 25% veliparib dose increments, and not exceeding single agent veliparib RPTD of 400 mg BID) 
may be evaluated at the discretion of the sponsor.  The alternative dosing schedules can include dosing 
veliparib Day –2 to 12 (14-day schedule) and/or Day –2 to 19 (continuous schedule) of 21 day Cycle.

Methodology (Continued):
Phase 1 Dose Escalation (Continued):
The initial dose for these schedules will be 200 mg BID or the maximum administered dose (MAD), not 
exceeding the MTD, in the 7-day schedule.  The 14-day schedule will be explored prior to continuous 
dosing schedule.  Reduced or interim dose levels may be evaluated based on review of the safety and 
PK.
A "3 + 3" escalation rule will be used for the dose-escalation portion of this study, with a condition 
applied for the Dose Level 1, which will allow 3 additional subjects to be entered in Dose Level 1 if 2 of 
6 initial subjects experience DLTs.  Enrollment of the 3 additional subjects at all dose levels will depend 
on a review of the specific DLTs observed and discussion with the Investigators.
Dose-Escalation Criteria:
AEs, clinical laboratory results, and vital signs will be assessed throughout the study in each 
dose-escalation cohort.
DLTs will be assessed in each dose-escalation cohort during the DLT observation period
(Cycle 1 Day –2 to pre-dose on Cycle 2 Day 1).  Based on the safety and tolerability of study drugs after 
the first cycle of treatment has been completed in at least 3 subjects, escalation to a subsequent dose 
level or expansion of the current dose level will occur based upon the following criteria:

Methodology (Continued):
Dose-Escalation Criteria (Continued):
Number of Subjects with 
DLT in the First Cycle
Escalation Decision Rule
0 out of 3
Enter 3 subjects at the next dose level.
1 out of 3
Add 3 more subjects at current dose level.  If AbbVie or the investigator 
considers the DLT(s) clinically significant, AbbVie will determine if it 
is appropriate to add more patients at this dose level.
!
If < 2 of 6 subjects (or < 33% of subjects) experience DLT, dose 
escalation will proceed to the next dose level.
!
If ≥ 2 of total 6 subjects (or ≥ 33% of subjects) experience DLTs, 
then dose escalation will be stopped.*
≥ 2 out of 3 or 6
Dose escalation will be stopped.  *Additional subjects will be enrolled 
at the previous lower dose level as needed.  The following exceptions 
apply to Dose Level 1:
!
If 2 of 6 initial subjects at Dose Level 1 experience DLTs, 
3 additional subjects may be entered and the cohort will be 
expanded up to 9 subjects for further DLT assessment.  
o
Enrollment of the 3 additional subjects will depend on a review 
of the specific DLTs observed and discussion with the 
Investigators.  
!
If 2 of 9 subjects at Dose Level 1 experience DLTs, then escalation 
to the next dose level may proceed.
!
If > 2 of 9 subjects in Dose Level 1 experience drug-related DLTs, 
dose-escalation will stop.
*
If 2 out of 6 subjects experience different DLTs, for example nausea and neutropenia, the data will be reviewed 
by the investigator and AbbVie to determine if 3 additional subjects should be added at that dose level.  If 
3 subjects will be added and none experience DLTs, this dose level will be declared the MTD.
An MTD and/or maximum administered dose (MAD), and RPTD, will be determined.  The MTD is 
defined as the maximum dose at which < 2 of 6 or ≤ 2 of 9 subjects experience a DLT during the DLT 
observation period.  The MAD is defined as the highest dose tested.  Both MAD and MTD may be 
determined independently for each tested dosing schedule of veliparib.  The RPTD and schedule will be 
determined based on the assessment of the observed toxicities, the MTD or MAD, and the overall safety 
profile of the study drug.  The RPTD cannot exceed the lower of MTD or MAD.  At the RPTD and 
schedule, additional subjects will be added as needed so that a total of at least 9 subjects will be treated 
at the RPTD during the dose escalation part of the study.

Methodology (Continued):
DLT Definition:
DLT is defined as any of the following drug-related toxicities occurring during the DLT observation 
period in any of the dose-escalation cohorts, with grading according to the National Cancer Institute 
(NCI) Common Toxicity Criteria for Adverse Events (CTCAE), Version 4.0:
1.
Cycle 1 events associated with treatment delay > 14 days in initiating Cycle 2:
a.
Grade 4 thrombocytopenia (platelets < 25.0 × 109/L)
b.
Grade 4 neutropenia (absolute neutrophil count (ANC) < 0.5 × 109/L)
c.
Grade 3 febrile neutropenia with fever lasting for > 7 days
d.
Grade 4 febrile neutropenia of any duration
NOTE:  Delay of more than 14 days in initiating Cycle 2 due to factors not directly related to 
treatment-emergent toxicity will not be considered a DLT.
2.
Grade ≥ 3 non-hematologic toxicity that represents at least 2 grade increase from baseline and is 
attributed to veliparib treatment:
a.
Exclusion:  nausea and vomiting lasting ≤ 48 hours or inadequately treated
b.
Exclusion:  electrolyte abnormalities resolving within ≤ 24 hours
c.
Exclusion:  hypersensitivity reactions
d.
Exclusion:  alopecia
3.
Grade 2 non-hematologic toxicity that represents at least 2 grade increase from baseline, is 
attributed to veliparib treatment and requires a treatment delay of > 14 days in initiation of Cycle 2
4.
Any toxicity that represents at least 2 grade increase from baseline, is attributed to veliparib 
treatment and requires at least one of:
a.
Dose modification within Cycle 1
b.
Omission of carboplatin, > 1 daily etoposide dose, or > 30% veliparib doses in Cycle 1
Subjects experiencing DLT(s) during DLT observation period (Cycle 1 Day –2 to pre-dose Cycle 2 
Day 1) will require an interruption and possible discontinuation from further participation in the study.  
Veliparib may be reintroduced at a reduced dose, if the toxicity returns to ≤ Grade 1 or to baseline if 
Grade 2 at study entry.  All decisions regarding continued dosing for individual subjects who experience 
a DLT will be medically managed by the investigator in conjunction with the AbbVie Medical Monitor.
Pharmacokinetics:
Pharmacokinetics of veliparib and etoposide will be assessed to determine the drug-drug interactions.  
Further pharmacokinetics of carboplatin will be assessed on Day 1 of Cycle 1.
Phase 2
In the Phase 2 double-blinded portion of the study subjects with treatment-naïve ED SCLC will be 
randomized to one of three treatment arms in 1:1:1 ratio: 
●
Arm A:  veliparib in combination with carboplatin/etoposide followed by veliparib 
monotherapy
●
Arm B:  veliparib in combination with carboplatin/etoposide followed by placebo monotherapy
●
Arm C:  placebo in combination with carboplatin/etoposide followed by placebo monotherapy

Methodology (Continued):
Dose-Escalation Criteria (Continued):
Phase 2 (Continued):
Subjects in all Phase 2 study arms will receive a minimum of 4 cycles of combination therapy unless 
disease progression or unacceptable toxicity warrants earlier discontinuation from the treatment.  
Additional 2 cycles of combination therapy (e.g., up to a total of 6 cycles) may be administered at the 
investigators discretion if subject status at the completion of initial 4 cycles warrants continued 
treatment.  In the combination cycles of Arms A and B, veliparib will be administered at the RPTD 
defined in the Phase 1 portion of the study, Arm C will receive matching placebo.  After the completion 
of at least 4 chemotherapy combination cycles subjects without evidence of disease progression will 
receive veliparib at 400 mg BID continuous dosing (Arms A), or matching  placebo (Arms B and C), 
until disease progression or unacceptable toxicity occurs.
Subjects who will be receiving prophylactic cranial irradiation (PCI) will have maintenance veliparib 
interrupted for the duration of radiotherapy.
Subject randomization for Phase 2 will be stratified by baseline LDH level (> ULN versus ≤ ULN), and 
gender.
Pharmacodynamics (Dose Escalation and Phase 2):
Research to find biomarkers that may serve as surrogates for clinical endpoints in future veliparib studies 
or that may be predictive of veliparib activity will be conducted.  Serum, plasma, blood and tissue 
samples will be collected at designated time points throughout the study.
Tumor Assessments and Safety Follow-Up
Tumor assessments will be performed until disease progression.  Tumor assessment and assessment of 
response will occur every 6 weeks (± 1 week) for the first 24 weeks after the first dose of study drugs, 
then every 9 weeks (± 1 week) thereafter.  Tumor response will be determined according to the Response 
Evaluation Criteria in Solid Tumors (RECIST), Version 1.1.  Subjects will continue on study until they 
meet defined discontinuation criteria.  When the investigator has determined that a subject should 
discontinue the study, a Final Visit will be conducted.  Subjects will have a 30-Day Safety Follow-Up 
Visit following the last dose of study drugs or placebo (dependent on cohort).  If the subject begins 
another treatment regimen directly following protocol treatment and if a 30-Day Follow-Up Visit is not 
possible, all adverse events ongoing as of the end of study must be followed to a satisfactory conclusion.

166
Criteria for Evaluation (Continued):
Efficacy (Continued):
Overall survival will be determined by the Investigator at assessments throughout therapy.  After the 
final visit, survival information will be collected via the Interactive Response Technology (IRT) at 
two month intervals (or as requested by sponsor to support data analysis).
ECOG performance status will be determined by the Investigator at each assessment.  
Pharmacokinetic:
Blood samples for pharmacokinetics of veliparib, carboplatin and etoposide will be collected at 
designated time points throughout the study.  Pharmacokinetics of veliparib and etoposide will be 
assessed to determine the drug-drug interactions.  In addition, pharmacokinetics of carboplatin will be 
determined.
Pharmacodynamic:
Research to find biomarkers that may be predictive of veliparib activity will be conducted.  Serum, 
plasma, blood and archived tissue samples will be collected at designated time points throughout the 
study.
Pharmacogenetic:
DNA samples may be analyzed for genetic factors contributing to the subject's response to veliparib, or 
other study treatment, in terms of pharmacokinetics, efficacy, tolerability and safety.
Safety:
Adverse events, laboratory profiles, physical examinations, vital signs and neurological assessments will 
be evaluated and recorded throughout the study.
Statistical Methods:
Efficacy:
The following end point will be analyzed using data obtained from subjects in Phase 1:
Objective Response Rate
The proportion of subjects with objective response as assessed by the investigator using RECIST 1.1 will 
be calculated for all dosed subjects.
The following end point will be analyzed using data obtained from subjects in Phase 2:
Progression-Free Survival
Progression-Free Survival will be defined as the number of days from the date of randomization to the 
date of earliest disease progression or death.  All disease progression will be included regardless whether 
the event occurred while the subject was taking study drug or had previously discontinued study drug.  If 
the subject does not experience disease progression or death, then the data will be censored at the date of 
the last disease assessment.
Overall Survival
Overall survival will be defined as the number of days from the date of randomization to the date of 
death.  For subjects who did not die, their data will be censored at the date of last study visit or the last 
known date to be alive, whichever is later.  
Objective Response Rate
The proportion of subjects with objective response (CR or PR) as assessed by the investigator using 
RECIST 1.1 will be evaluated for randomized subjects.

167
Statistical Methods (Continued):
Efficacy (Continued):
Duration of Overall Response
Duration of overall response will be defined as the number of days from the date of first response (CR or 
PR) to the earliest documentation of progressive disease.  If a subject is still responding, then the 
subject's data will be censored at the date of the subject's last available disease assessment.  For subjects 
who never experience response, the subject's data will not be included in the analysis.
Performance Status
Changes and/or percent changes from baseline will be summarized using descriptive statistics for each 
scheduled post-baseline visit and for the Final Visit for ECOG performance status.  Post-baseline 
measurements more than 30 days after the last dose of study drug will not be included.  Subjects that do 
not have a baseline measurement or do not have any post-baseline measurements will not be included.
Pharmacokinetic:
Plasma concentrations of veliparib, etoposide, and carboplatin and pharmacokinetic parameter values 
will be tabulated for each subject and each dose level, and summary statistics will be computed for each 
sampling time and each parameter.
The effects of co-administration of veliparib on etoposide pharmacokinetics will be addressed by 
analyzing the Cycle 1, Day 1 (veliparib with carboplatin and etoposide) and Cycle 2 Day 1 (carboplatin 
and etoposide alone) etoposide pharmacokinetic variables, including Tmax, dose normalized Cmax and 
dose normalized AUC.
Pharmacodynamic:
Biomarker results will be tabulated for each subject and each regimen, and summary statistics will be 
computed for each sampling time and each parameter.  The relationship between biomarker status and 
clinical outcome or drug exposure may be examined.
Safety:
●
The safety of veliparib in combination with carboplatin/etoposide will be assessed by 
evaluating the study drugs exposure, adverse events, serious adverse events, all deaths, as well 
as changes in laboratory determinations and vital sign parameters.  Safety will be summarized 
per dose level using descriptive statistics for the dose escalation cohorts and per treatment arm 
in Phase 2.
●
RPTD will be determined based on the rate of DLTs and overall tolerability of the combination 
of veliparib, carboplatin and etoposide with at least 9 subjects treated at the RPTD in Phase 1 
and will be further evaluated in Phase 2.

Investigators:  
Multicenter
Study Sites:  
Approximately 65 globally
Study Population:  
Phase 1:  Histologically or cytologically confirmed extensive stage disease SCLC or any other 
advanced/metastatic solid tumor for which carboplatin/etoposide treatment is considered appropriate.
Phase 2:  Histologically or cytologically confirmed treatment-naïve extensive stage disease SCLC.
Number of Subjects to be Enrolled:  
Phase 1 Dose Escalation portion:  Approximately:  35
Phase 2 Randomized Double-Blind portion:  Approximately:  180
Methodology:
This is a Phase 1 dose escalation and Phase 2 randomized double-blind study.
Screening Procedures:
Screening procedures should be performed within 28 days of Cycle 1 Day –2.  If the screening visit is 
performed greater than 7 days prior to Cycle 1 Day –2, the physical exam, laboratory tests, and 
pregnancy test (for female subjects of childbearing potential) must be repeated on Cycle 1 Day –2.  Vital 
signs and performance status assessments will be performed on Cycle 1 Day –2 for all subjects.  
Baseline radiographic tumor assessments per computed tomography (CT) with IV contrast/magnetic 
resonance imaging (MRI) of the chest, abdomen, and pelvis will be conducted within 21 days prior to 
Cycle 1 Day –2.  If CNS metastases are suspected, a head CT must also be performed at screening.  If 
the subject is unable to undergo a CT scan with IV contrast due to allergy or renal insufficiency, a non-
contrast CT may be performed.  Magnetic resonance imaging (MRI) can be conducted in cases where 
local laws/requirements mandate, but should have Sponsor approval prior to performing the MRI.
Phase 1 Dose Escalation:
For subjects in the dose escalation portion of the study, each subject will participate in only 1 dose group 
and there is no provision for intra-subject dose-escalation.  Study procedures will be provided in the 
Schedule of Assessments and Pharmacokinetic and Pharmacodynamic tables.

Methodology (Continued):
Phase 1 Dose Escalation (Continued):
The Phase 1 portion of this study will evaluate the safety, tolerability, dose limiting toxicities (DLTs), 
RPTD, pharmacokinetics (PK), and pharmacodynamics (PD), of veliparib/carboplatin/etoposide 
combination in subjects diagnosed with Extensive Stage Disease Small Cell Lung Cancer or, other 
advanced/metastatic solid tumor for which carboplatin/etoposide treatment is considered appropriate.  
Veliparib will be administered on Days –2 to 5 (7-day schedule), and, if the MTD of the 7-day schedule 
is not reached at ≤ 200 mg BID veliparib dose level, may be administered on Days –2 to 12 (14-day 
schedule) and/or Days –2 to 19 (continuous schedule) orally BID, in combination with carboplatin area 
under the curve 5 mg/mL*min administered on Day 1 and etoposide 100 mg/m2 administered on Days 1 
to 3 via intravenous (IV) infusion in 21-day cycles.  An exception would be for the Phase 1 Cycle 2:  In 
the 7-day schedule, veliparib in Cycle 2 will be administered on Days 2 to 5 and for the 14-day schedule, 
Days 2 to 12 (veliparib dose on Cycle 2 Days –2 and –1 and Cycle 2 Day 1 will be omitted to allow for 
the evaluation of drug-drug interaction of veliparib with etoposide).
Upon completion of 4 cycles of combination therapy, subjects without evidence of disease progression 
will continue on veliparib 400 mg BID until disease progression or unacceptable toxicity.  Subjects who 
will be receiving prophylactic cranial irradiation (PCI) will have maintenance veliparib interrupted for 
the duration of radiotherapy.
All subjects will be monitored for DLTs during the DLT observation period (Cycle 1 Day –2 to pre-dose 
Cycle 2 Day 1), and treatment-related adverse events (AEs) will be evaluated throughout the course of 
the study for evidence of acute, delayed, or cumulative toxicities.
The dose levels of veliparib to be evaluated in the dose-escalation portion of this study were determined 
based on the outcome of prior clinical studies of veliparib as well as on pre-clinical toxicology, 
toxicokinetic, and nonclinical anti-tumor efficacy studies.  The following dose levels may be evaluated 
in the dose-escalation portion of the study:  80, 120, 160, 200, and 240 mg BID.  Reduced dose levels 
may be evaluated based upon review of subject safety and PK data.  Intermediate dose levels may be 
evaluated based upon review of subject safety including, but not limited to, Grade 2 study-drug related 
AEs.  If the MTD is not reached at veliparib 200 mg BID dose level, higher dose levels (with no more 
than 25% veliparib dose increments, and not exceeding single agent veliparib RPTD of 400 mg BID) 
may be evaluated at the discretion of the sponsor.  The alternative dosing schedules can include dosing 
veliparib Day –2 to 12 (14-day schedule) and/or Day –2 to 19 (continuous schedule) of 21 day Cycle.  
The initial dose for these schedules will be 200 mg BID or the maximum administered dose (MAD), not 
exceeding the MTD, in the 7-day schedule.  The 14-day schedule will be explored prior to continuous 
dosing schedule.  Reduced or interim dose levels may be evaluated based on review of the safety and 
PK.
A "3 + 3" escalation rule will be used for the dose-escalation portion of this study, with a condition 
applied for the Dose Level 1, which will allow 3 additional subjects to be entered in Dose Level 1 if 2 of 
6 initial subjects experience DLTs.  Enrollment of the 3 additional subjects at all dose levels will depend 
on a review of the specific DLTs observed and discussion with the Investigators.
Dose-Escalation Criteria:
AEs, clinical laboratory results, and vital signs will be assessed throughout the study in each 
dose-escalation cohort.

Methodology (Continued):
Dose-Escalation Criteria (Continued):
DLTs will be assessed in each dose-escalation cohort during the DLT observation period
(Cycle 1 Day –2 to pre-dose on Cycle 2 Day 1).  Based on the safety and tolerability of study drugs after 
the first cycle of treatment has been completed in at least 3 subjects, escalation to a subsequent dose 
level or expansion of the current dose level will occur based upon the following criteria:
Number of Subjects with 
DLT in the First Cycle
Escalation Decision Rule
0 out of 3
Enter 3 subjects at the next dose level.
1 out of 3
Add 3 more subjects at current dose level.  If AbbVie or the investigator 
considers the DLT(s) clinically significant, AbbVie will determine if it 
is appropriate to add more patients at this dose level.
!
If < 2 of 6 subjects (or < 33% of subjects) experience DLT, dose 
escalation will proceed to the next dose level.
!
If ≥ 2 of total 6 subjects (or ≥ 33% of subjects) experience DLTs, 
then dose escalation will be stopped.*
≥ 2 out of 3 or 6
Dose escalation will be stopped.  *Additional subjects will be enrolled 
at the previous lower dose level as needed.  The following exceptions 
apply to Dose Level 1:
!
If 2 of 6 initial subjects at Dose Level 1 experience DLTs, 
3 additional subjects may be entered and the cohort will be 
expanded up to 9 subjects for further DLT assessment.  
o
Enrollment of the 3 additional subjects will depend on a review 
of the specific DLTs observed and discussion with the 
Investigators.  
!
If 2 of 9 subjects at Dose Level 1 experience DLTs, then escalation 
to the next dose level may proceed.
!
If > 2 of 9 subjects in Dose Level 1 experience drug-related DLTs, 
dose-escalation will stop.
*
If 2 out of 6 subjects experience different DLTs, for example nausea and neutropenia, the data will be reviewed 
by the investigator and AbbVie to determine if 3 additional subjects should be added at that dose level.  If 
3 subjects will be added and none experience DLTs, this dose level will be declared the MTD.
An MTD and/or maximum administered dose (MAD), and RPTD, will be determined.  The MTD is 
defined as the maximum dose at which < 2 of 6 or ≤ 2 of 9 subjects experience a DLT during the DLT 
observation period.  The MAD is defined as the highest dose tested.  Both MAD and MTD may be 
determined independently for each tested dosing schedule of veliparib.  The RPTD and schedule will be 
determined based on the assessment of the observed toxicities, the MTD or MAD, and the overall safety 
profile of the study drug.  The RPTD cannot exceed the lower of MTD or MAD.  At the RPTD and 
schedule, additional subjects will be added as needed so that a total of at least 9 subjects will be treated 
at the RPTD during the dose escalation part of the study.

Methodology (Continued):
DLT Definition:
DLT is defined as any of the following drug-related toxicities occurring during the DLT observation 
period in any of the dose-escalation cohorts, with grading according to the National Cancer Institute 
(NCI) Common Toxicity Criteria for Adverse Events (CTCAE), Version 4.0:
1.
Cycle 1 events associated with treatment delay > 14 days in initiating Cycle 2:
a.
Grade 4 thrombocytopenia (platelets < 25.0 × 109/L)
b.
Grade 4 neutropenia (absolute neutrophil count (ANC) < 0.5 × 109/L)
c.
Grade 3 febrile neutropenia with fever lasting for > 7 days
d.
Grade 4 febrile neutropenia of any duration
NOTE:  Delay of more than 14 days in initiating Cycle 2 due to factors not directly related to 
treatment-emergent toxicity will not be considered a DLT.
2.
Grade ≥ 3 non-hematologic toxicity that represents at least 2 grade increase from baseline and is 
attributed to veliparib treatment:
a.
Exclusion:  nausea and vomiting lasting ≤ 48 hours or inadequately treated
b.
Exclusion:  electrolyte abnormalities resolving within ≤ 24 hours
c.
Exclusion:  hypersensitivity reactions
d.
Exclusion:  alopecia
3.
Grade 2 non-hematologic toxicity that represents at least 2 grade increase from baseline, is 
attributed to veliparib treatment and requires a treatment delay of > 14 days in initiation of Cycle 2
4.
Any toxicity that represents at least 2 grade increase from baseline, is attributed to veliparib 
treatment and requires at least one of:
a.
Dose modification within Cycle 1
b.
Omission of carboplatin, > 1 daily etoposide dose, or > 30% veliparib doses in Cycle 1
Subjects experiencing DLT(s) during DLT observation period (Cycle 1 Day –2 to pre-dose Cycle 2 
Day 1) will require an interruption and possible discontinuation from further participation in the study.  
Veliparib may be reintroduced at a reduced dose, if the toxicity returns to ≤ Grade 1 or to baseline if 
Grade 2 at study entry.  All decisions regarding continued dosing for individual subjects who experience 
a DLT will be medically managed by the investigator in conjunction with the AbbVie TA MD.
Pharmacokinetics:
Pharmacokinetics of veliparib and etoposide will be assessed to determine the drug-drug interactions.  
Further pharmacokinetics of carboplatin will be assessed on Day 1 of Cycle 1.
Phase 2 Randomized Double-Blind
The veliparib dose and schedule for the Phase 2 was determined to be 240 mg BID on a 14 day schedule 
based on the analysis of Phase 1 data.
Approximately 180 total subjects with treatment-naïve ED SCLC will be enrolled at the 240 mg BID 
veliparib/placebo dose and 14 day schedule in the Phase 2 double-blinded portion of the study.  They 
will be randomized in a 1:1:1 ratio to one of three treatment arms: 
●
Arm A:  veliparib in combination with carboplatin/etoposide followed by veliparib 
monotherapy
●
Arm B:  veliparib in combination with carboplatin/etoposide followed by placebo monotherapy

Methodology (Continued):
Phase 2 Randomized Double-Blind (Continued)
!
Arm C:  placebo in combination with carboplatin/etoposide followed by placebo monotherapy
Subjects in all Phase 2 study arms will receive a minimum of 4 cycles of combination therapy unless 
disease progression or unacceptable toxicity warrants earlier discontinuation from the treatment.  
Additional 2 cycles of combination therapy (e.g., up to a total of 6 cycles) may be administered at the 
investigators discretion if subject status at the completion of initial 4 cycles warrants continued 
combination treatment and/or if local SOC guidelines require 6 cycles of platinum-based therapy.  In the 
combination cycles of Arms A and B, subjects will receive veliparib at 240 mg BID on a 14-day 
schedule, Arm C will receive matching placebo.  After completion of the chemotherapy combination 
cycles (at least 4), subjects without evidence of disease progression will receive veliparib at 400 mg BID 
continuous dosing (21-day cycles) (Arms A), or matching placebo (Arms B and C) as per treatment arm 
assignment, until disease progression or unacceptable toxicity occurs.  
Subjects who will be receiving prophylactic cranial irradiation (PCI) will have maintenance veliparib 
interrupted for the duration of radiotherapy.
Subject randomization for Phase 2 will be stratified by baseline LDH level (> ULN versus ≤ ULN), and 
gender.
Pharmacodynamics (Phase 1 Dose Escalation and Phase 2 Randomized Double-Blind):
Research to find biomarkers that may serve as surrogates for clinical endpoints in future veliparib studies 
or that may be predictive of veliparib activity will be conducted.  Serum, plasma, blood and tissue 
samples will be collected at designated time points throughout the study.
Tumor Assessments and Safety Follow-Up
Tumor assessments will be performed until radiographic disease progression.  Tumor assessment and 
assessment of response will occur every 6 weeks (± 1 week) from C1D-2 for the first 24 weeks (Phase 1) 
or 30 weeks (Phase 2), then every 9 weeks (± 1 week) thereafter.  Tumor response will be determined 
according to the Response Evaluation Criteria in Solid Tumors (RECIST), Version 1.1.  Subjects will 
continue on study until they meet defined discontinuation criteria.  When the investigator has determined 
that a subject should discontinue the study, a Final Visit will be conducted.  Subjects will have a 30-Day 
Follow-Up Visit following the last dose of study drugs or placebo (Phase 2, dependent on treatment 
arm).  If the subject begins another treatment regimen directly following protocol treatment and if a 
30-Day Follow-Up Visit is not possible, all adverse events ongoing as of the end of study must be 
followed to a satisfactory conclusion.

Criteria for Evaluation:
Efficacy:
Progression-free survival (PFS) will be derived according to disease progression (radiographic 
progression per RECIST version 1.1) or death.  Radiographic tumor assessments for response will be 
conducted by CT scanning at baseline, every 6 weeks from C1D-2 for the first 24 weeks (Phase 1) or 
30 weeks (Phase 2), then every 9 weeks until disease progression.
Objective response rate (ORR) will be derived per RECIST version 1.1.  Radiographic tumor 
assessments for response will be conducted by CT scanning at baseline, every 6 weeks from C1D-2 for 
the first 24 weeks (Phase 1) or 30 weeks (Phase 2), then every 9 weeks until disease progression.
Duration of overall response (DOR) will be derived according to disease progression (radiographic 
progression per RECIST version 1.1). 
Overall survival will be determined by the Investigator at assessments throughout therapy.  After the 
final visit, survival information will be collected via electronic data capture (EDC) at 2 month intervals 
(or as requested by sponsor to support data analysis).
ECOG performance status will be determined by the Investigator at each assessment.  
Pharmacokinetic:
Blood samples for pharmacokinetics of veliparib, carboplatin (Phase 1 Dose Escalation only) and 
etoposide (Phase 1 Dose Escalation only) will be collected at designated time points throughout the 
study.  Pharmacokinetics of veliparib and etoposide will be assessed to determine the drug-drug 
interactions.  In addition, pharmacokinetics of carboplatin will be determined.

177
Criteria for Evaluation (Continued):
Pharmacodynamic:
Research to find biomarkers that may be predictive of veliparib activity will be conducted.  Serum, 
plasma, blood and archived tissue samples will be collected at designated time points throughout the 
study.
Pharmacogenetic:
DNA samples may be analyzed for genetic factors contributing to the subject's response to veliparib, or 
other study treatment, in terms of pharmacokinetics, efficacy, tolerability and safety.
Safety:
Adverse events, laboratory profiles, physical examinations, vital signs and neurological assessments will 
be evaluated and recorded throughout the study.
Statistical Methods:
Efficacy:
The following end point will be analyzed using data obtained from subjects in Phase 1 and Phase 2 
separately:
Objective Response Rate
The proportion of subjects with objective response (CR or PR) as assessed by the investigator using 
RECIST 1.1 will be calculated for all dosed subjects.
The following end point will be analyzed using data obtained from subjects in Phase 2:
Progression-Free Survival
Progression-Free Survival will be defined as the number of days from the date of randomization to the 
date of earliest radiographic disease progression or death.  All disease progression will be included 
regardless whether the event occurred while the subject was taking study drug or had previously 
discontinued study drug.  If the subject does not experience disease progression or death, then the data 
will be censored at the date of the last radiographic disease assessment.
Overall Survival
Overall survival will be defined as the number of days from the date of randomization to the date of 
death.  For subjects who did not die, their data will be censored at the date of last study visit or the last 
known date to be alive, whichever is later.  
Duration of Overall Response
Duration of overall response will be defined as the number of days from the date of first response (CR or 
PR) to the earliest documentation of radiographic progressive disease.  If a subject is still responding, 
then the subject's data will be censored at the date of the subject's last available radiographic disease 
assessment.  For subjects who never experience response, the subject's data will not be included in the 
analysis.
Performance Status
Changes and/or percent changes from baseline will be summarized using descriptive statistics for each 
scheduled post-baseline visit and for the Final Visit for ECOG performance status.  Post-baseline 
measurements more than 30 days after the last dose of study drug will not be included.  Subjects that do 
not have a baseline measurement or do not have any post-baseline measurements will not be included.

Statistical Methods (Continued):
Pharmacokinetic:
Plasma concentrations of veliparib, etoposide, and carboplatin and pharmacokinetic parameter values 
will be tabulated for each subject and each dose level, and summary statistics will be computed for each 
sampling time and each parameter.
The effects of co-administration of veliparib on etoposide pharmacokinetics will be addressed by 
analyzing the Cycle 1 Day 1 (veliparib with carboplatin and etoposide) and Cycle 2 Day 1 (carboplatin 
and etoposide alone) etoposide pharmacokinetic variables, including Tmax, dose normalized Cmax and 
dose normalized AUC.
Pharmacodynamic:
Biomarker results will be tabulated for each subject and each regimen, and summary statistics will be 
computed for each sampling time and each parameter.  The relationship between biomarker status and 
clinical outcome or drug exposure may be examined.
Safety:
●
The safety of veliparib in combination with carboplatin/etoposide will be assessed by 
evaluating the study drugs exposure, adverse events, serious adverse events, all deaths, as well 
as changes in laboratory determinations and vital sign parameters.  Safety will be summarized 
per dose level using descriptive statistics for the dose escalation cohorts and per treatment arm 
in Phase 2.
●
RPTD was determined based on the rate of DLTs and overall tolerability of the combination of 
veliparib, carboplatin and etoposide with at least 9 subjects treated at the RPTD in Phase 1 and 
will be further evaluated in Phase 2.

First paragraph, first sentence previously read:
This study proposes to establish the recommended Phase 2 dose and to evaluate clinical 
outcomes for subjects with ED SCLC treated with veliparib added to standard therapy 
with carboplatin and etoposide.

The Phase 1 Dose Escalation portion of this study proposed to establish the recommended 
Phase 2 dose and veliparib schedule.  These were determined to be veliparib 240 mg BID 
on Days –2 – 12 (14-Day schedule) in combination with carboplatin AUC 5 mg/ml*hr on 
Day 1 and etoposide 100 mg/m2 on Days 1 – 3 of 21-Day cycle.  The Phase 2 portion of 
this study proposes to evaluate clinical outcomes for subjects with ED SCLC treated with 
veliparib added to standard therapy with carboplatin and etoposide.

Screening Procedures 
Screening procedures should be performed within 28 days prior to Cycle 1 Day –2.  If the 
screening visit is performed greater than 7 days prior to Cycle 1 Day –2, the physical 
exam, laboratory tests, and pregnancy test (for female subjects of childbearing potential) 
must be repeated on Cycle 1 Day –2.  Vital signs and performance status assessments will 
be performed on Cycle 1 Day –2 for all subjects.  Baseline radiographic tumor 
assessments per computed tomography (CT)/magnetic resonance imaging (MRI) of the 
chest, abdomen, and head will be conducted within 21 days prior to Cycle 1 Day –2.

Transition from Phase 1 to Phase 2
Once the veliparib RPTD and schedule is determined, the veliparib RPTD and schedule 
will be communicated to all participating research sites prior to the start of enrollment into 
the Phase 2.  Subjects from the Phase 1 Dose Escalation portion are not eligible for 
enrollment into the Phase 2 portion, but may continue to receive veliparib, carboplatin and 
etoposide at the assigned dose and schedule as long as they tolerate the study drug, show 
no evidence of disease progression, and do not meet any of the criteria for subject 
discontinuation (Section 5.4.1).

Subsection title and text previously read:
Randomized Double-Blind Phase 2
In the Phase 2 double-blinded portion of the study, subjects with treatment-naïve ED 
SCLC will be randomized in a 1:1:1 ratio to one of three treatment arms: 
Arm A:  RPTD of veliparib in combination with carboplatin/etoposide followed by 
veliparib 400 mg BID monotherapy
Arm B:  RPTD of veliparib in combination with carboplatin/etoposide followed by 
placebo monotherapy
Arm C:  placebo in combination with carboplatin/etoposide followed by placebo 
monotherapy
Subjects in all Phase 2 study arms will receive a minimum of 4 cycles of combination 
therapy unless disease progression or unacceptable toxicity warrants earlier 
discontinuation from the treatment.  Additional 2 cycles of combination therapy (e.g., up

to a total of 6 cycles) may be administered at the investigators discretion if subject status 
at the completion of initial 4 cycles warrants continued treatment.  In the combination 
cycles of Arms A and B veliparib will be administered at the RPTD defined in the Phase 1 
portion of the study, Arm C will receive matching placebo.  After completion of the 
chemotherapy combination cycles (at least 4), subjects without evidence of disease 
progression will receive veliparib at 400 mg BID continuous dosing (Arms A), or 
matching placebo (Arms B and C), until disease progression or unacceptable toxicity 
occurs (Figure 2).  Subjects who will be receiving prophylactic cranial irradiation (PCI) 
will have maintenance veliparib interrupted for the duration of radiotherapy as described 
in Section 5.2.3.2.
Subject randomization for Phase 2 will be stratified by baseline LDH level (> ULN versus

local SOC guidelines require 6 cycles of platinum-based therapy.  In the combination 
cycles of Arms A and B, subjects will receive veliparib at 240 mg BID on a 14-day 
schedule, Arm C will receive matching placebo.  After completion of the chemotherapy 
combination cycles (at least 4), subjects without evidence of disease progression will 
receive veliparib at 400 mg BID continuous dosing (21-day cycles) (Arms A), or 
matching placebo (Arms B and C) as per treatment arm assignment, until disease

will be determined according to the Response Evaluation Criteria in Solid Tumors 
(RECIST), Version 1.1.
In the Phase 1 portion, subjects will receive veliparib BID in combination with 
carboplatin/etoposide for up to a maximum 4 cycles of treatment.  In the Phase 2 portion, 
subjects will receive veliparib or placebo BID as applicable in combination with 
carboplatin/etoposide for up to 6 cycles of treatment.  In Phase 1, subjects that do not 
progress according to a radiographic assessment (CT) at Cycle 4 may continue in the 
monotherapy portion veliparib or placebo as appropriate starting at Cycle 5 Day 1.  In 
Phase 2, subjects that do not progress according to a radiographic assessment (CT) at 
completion of at least 4 combination chemotherapy Cycles may continue in the 
monotherapy portion veliparib or placebo starting at Maintenance Day 1.  In the Phase 2 
portion, subjects discontinuing both carboplatin and etoposide due to toxicity and without 
evidence of disease progression prior to the completion of 4 cycles of combination 
therapy may transition to monotherapy veliparib/placebo as per treatment arm assignment.  
All subjects will remain on study until reaching a protocol defined event of disease 
progression.  Subjects in the Phase 2 portion of the study, who are discontinued from 
study treatment due to an adverse event, will remain on study/off study drugs until 
reaching an event of disease progression.
When an investigator has determined that a subject has met the protocol defined criteria 
for disease progression, as outlined in Section 5.3.3.1, a Final Visit will be conducted.
All subjects will have one Follow-Up Visit approximately 30 days after the Final Visit.  
This Follow-Up Visit does not need to be performed for subjects who have had a Final 
Visit conducted ≥ 30 days after last dose of study drug.  If a subject is discontinued from 
the study with an ongoing adverse event or an unresolved clinically significant laboratory 
result, the site will attempt to provide follow-up until a satisfactory clinical resolution of 
the laboratory results or adverse event is achieved.
In the Phase 2 portion of the study, post treatment tumor assessments (if subject 
discontinues before disease progression is recorded), cancer treatments and survival

In-text table previously read:
Premedication:
The prophylactic antiemetics, including 5-HT3 antagonists, according to 
institution, National Comprehensive Cancer Network (NCCN), European 
Society for Medical Oncology (ESMO) or American Society of Clinical 
Oncology (ASCO) guidelines should be given, prior to administration of 
carboplatin and etoposide.  Prophylaxis with anti-emetics (e.g., 5-HT3 
antagonists such as ondansetron) is strongly recommended when initiating 
single agent veliparib maintenance therapy.
Anticancer Agents:
Other anticancer agents are not permitted during the treatment portion of the 
study.  All subjects will receive carboplatin + etoposide with veliparib/placebo 
at specified timepoints during the treatment portion of the study.  The locally 
approved carboplatin and etoposide product labels or SmPCs should be 
referenced to determine if there are any contraindications associated with 
concomitant medications (e.g., phenytoin, etc.).
Supportive Care:
Best supportive care and treatment will be given as appropriate to each subject 
(antiemetics, antibiotics, transfusions, nutritional support, non-radiation 
palliative treatment for pain, bisphosphonates or denosumab) according to 
institutional or clinical practice guidelines (e.g., ASCO, ESMO, or NCCN).
Growth Factors:
Biologic response modifiers administered for erythropoiesis 
(e.g., erythropoietin, darbepoetin alpha) and colony stimulating factors 
(e.g., neulasta, G-CSF, GM CSF, etc.) may be administered according to 
institutional or clinical practice guidelines (e.g., ASCO, ESMO, or NCCN).  
Growth factors prophylaxis will not be allowed in Cycle 1 (Day –2 through 
Day 21) of the dose escalation cohorts.
Radiation:
Prophylactic cranial irradiation (PCI) is allowed during the study in the 
maintenance phase of treatment at Investigators discretion.  The dose of PCI 
should be 24 Gy in 8 fractions of 3 Gy each, or per local treatment standards.  
Veliparib or placebo maintenance monotherapy will be held starting 2 days prior 
to the initiation of radiation therapy, throughout the radiation therapy and for 
4 days following radiation therapy.  Palliative radiation to a non-target lesion 
with the intent of symptom control is allowed; non-progressing status of lesion 
to be irradiated must be documented prior to the procedure.
Surgery:
If the subject requires surgery during the study, then this needs to be discussed 
with the AbbVie Medical Monitor.
Alternate Therapy:
No traditional herbal anti-cancer medicine (e.g., Chinese, Asian, etc.) may be 
taken concurrently with veliparib (a 14-day washout period must be 
documented).

Last paragraph previously read:
Screening procedures and assessments will occur within 28 days prior to Cycle 1 Day –2 
except for radiographic assessments that are to be performed within 21 days of Cycle 1 
Day –2.  For procedures performed at Screening and repeated, the later procedure 
performed prior to dosing will serve as a baseline for clinical assessment.  Subsequent 
study procedures should be performed approximately within ± 1 day on days of IV 
infusion of carboplatin and etoposide and ± 2 days for all safety visits and Cycle 5 of 
monotherapy and maintenance surrounding the scheduled study visit date.  Clinical 
laboratory tests can be performed up to 24 hours prior to dosing.
Has been changed to read:
Screening procedures should be performed within 28 days prior to Cycle 1 Day –2.  If the 
screening visit is performed greater than 7 days prior to Cycle 1 Day –2, the physical 
exam, laboratory tests, and pregnancy test (for female subjects of childbearing potential) 
must be repeated on Cycle 1 Day –2.  Vital signs and performance status assessments will 
be performed on Cycle 1 Day –2 for all subjects.  Baseline radiographic tumor 
assessments per computed tomography (CT) with IV contrast/magnetic resonance 
imaging (MRI) of the chest, abdomen, pelvis and head (if CNS metastases are suspected) 
will be conducted within 21 days prior to Cycle 1 Day –2.  If the subject is unable to

undergo a CT scan with IV contrast due to allergy or renal insufficiency, a non-contrast 
CT may be performed.  Magnetic resonance imaging (MRI) can be conducted in cases 
where local laws/requirements mandate, but should have Sponsor approval prior to 
performing the MRI.
For procedures performed at Screening and repeated, the later procedure performed prior 
to dosing will serve as a baseline for clinical assessment.  Subsequent study procedures 
should be performed approximately within ± 1 day on days of IV infusion of carboplatin 
and etoposide and ± 2 days for all safety visits and first Maintenance visit.  Clinical 
laboratory tests can be performed up to 48 hours prior to dosing.

defined tumor assessment schedule until reaching an event of radiographic progression. 
Subjects who discontinue all study drugs due to toxicity should have a 30-day Follow-up 
visit prior to entering into Post-Treatment Follow-Up to ensure all toxicities have 
resolved.  Subjects will have a Final Visit and be discontinued from the study upon 
reaching an event of radiographic progression, if the Investigator determines they should 
be discontinued for any other reason or if the subject withdraws consent.

Subjects who complete all Screening procedures and meet the eligibility criteria will 
proceed to dosing.  The site will access the IVR/IWR system at Screening and a unique 
subject number will be provided.
Subjects in Phase 2 will be randomized in a 1:1:1 ratio to carboplatin, etoposide, placebo, 
followed by placebo maintenance, or carboplatin, etoposide, veliparib followed by either 
veliparib or placebo maintenance.  A subject number will be assigned after the subject 
signs the informed consent.  The site can contact the system up to 4 calendar days prior to 
or on the subject's Cycle 1 Day –2 to obtain a Screening (subject) number.  Subjects who 
complete all Screening procedures and meet the eligibility criteria will proceed to 
randomization.  The site will contact the system prior to the subject's Cycle 1 Day –2 and 
a unique randomization number will be provided.

monitored by the same methods (unless medical contraindication is noted) until the earlier 
of disease progression or initiation of next line of treatment.
If a subject discontinues for reasons other than radiographic progression and if no tumor 
assessment has been performed with the last 4 weeks, a tumor assessment will be 
performed at the Final Visit.
If a subject is discontinued from the study with an ongoing adverse event or an unresolved 
laboratory result that is significantly outside of the reference range, the investigator will 
attempt to provide follow-up until a satisfactory clinical resolution of the laboratory result 
or adverse event is achieved.
In the event that a positive result is obtained on a pregnancy test for a subject or a subject 
reports becoming pregnant during the study, the administration of study drug to that 
subject must be discontinued immediately.  The investigator must report a pregnancy 
within 1 working day of the site being aware to one of the AbbVie representatives listed 
in Section 6.6 or Section 7.0.
Has been changed to read:
When a subject discontinuation from the study (without reaching a protocol-defined 
endpoint) is planned, the Investigator is to notify the AbbVie TA MD or the clinical team

subject care and safety are not compromised).  If not notified prior to discontinuation, the 
AbbVie TA MD may contact the site to discuss the reason for withdrawal from the study.
If a subject is discontinued from the study with an ongoing adverse event or an unresolved 
laboratory result that is significantly outside of the reference range, the investigator will

Post-Treatment Follow-Up
Phase 2 subjects who discontinue treatment for reasons other than radiographic 
progression will be monitored in the Post-Treatment Follow-Up period of the study by the 
same imaging method (unless medical contraindication is noted) until disease progression 
(Table 8).
Final Visit
The visit at which an investigator identifies disease progression or at which a subject 
meets other criteria for study discontinuation will be considered the Final Visit.  The 
reason(s) for the discontinuation from the study will be recorded and assessments will be 
performed per Table 7 and Table 8.  It is preferable that Final Visit procedures be 
conducted prior to the initiation of another anticancer therapy.  However, these procedures 
should not interfere with the initiation of any new treatments or therapeutic modalities that 
the Investigator feels are necessary to treat the subject's condition.
30-Day Follow-Up Visit
Subjects who discontinue treatment for reasons other than radiographic progression will 
have a Follow-Up Visit approximately 30 days after the last dose of study drug and will 
transition to Post-Treatment Follow-Up. 
Subjects who discontinue treatment due to radiographic progression and have a Final Visit 
within 30 days of last dose of study drug will have one Follow-Up Visit approximately

Subjects will receive veliparib, carboplatin and etoposide up to a maximum of 4 –
6 combination cycles or until reaching a protocol defined event of disease progression or 
experiencing unmanageable toxicity.  Dose reductions of carboplatin and etoposide will 
occur on the basis of the toxicity observed and may result in discontinuation of either 
agent.  The subject may continue on therapy with the remaining agent in combination with 
veliparib. At the Investigator's discretion, carboplatin and/or etoposide administration 
may continue after veliparib has been discontinued.  Suitable subjects will receive 
veliparib/placebo maintenance monotherapy as per treatment arm assignment until 
reaching a protocol defined event of disease progression or experiencing unmanageable 
toxicity.

Subsection Calculation of Carboplatin Dose
Delete:  subsection title and text
Calculation of Carboplatin Dose
The below guidance recommendation for carboplatin dose calculation is intended to 
reduce variability of carboplatin doses between sites. 
The initial dose of carboplatin must be calculated using GFR.  In the absence of renal 
toxicity greater than or equal to CTCAE Grade 2 (serum creatinine > 1.5 × ULN) or 
toxicity requiring dose modification, the dose of carboplatin does not need to be 
recalculated for subsequent cycles, but will be subject to dose modification for toxicity as 
noted in the protocol.
Carboplatin doses will be based on the subject's weight at baseline and should remain the 
same throughout the study.  However, the doses may be recalculated based on the 
subject's weight at each cycle, and need to be recalculated if the subject has a weight 
change of greater than or equal to 10% from baseline.
In subjects with an abnormally low serum creatinine (less than 0.7 mg/dL), the creatinine 
clearance should be estimated using a minimum value of 0.7 mg/dL.
CALVERT FORMULA:
Carboplatin dose (mg) = target AUC × (GFR + 25)
NOTE:  the GFR used in the Calvert formula cannot exceed 125 mL/min.
For the purposes of this protocol, the GFR is considered to be equivalent to the estimated 
creatinine clearance.  The estimated creatinine clearance (mL/min) is calculated by the 
method of Cockcroft-Gault using the following formula:
Creatinine Clearance (mL/min) = [140-Age (years)] × Weight (kg) / 
(72 × Ser Cr (mg/dL))

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
223
For female subjects:  multiply the result above by 0.85.
Notes:
Body mass index (BMI) should be calculated for each subject.  A BMI should be 
calculated using the following formula:
BMI = (Weight in kg) / (Height in meters)2
Actual weight should be used for estimation of GFR for subjects with BMI < 25.
Adjusted weight should be used for estimation of GFR for subjects with BMI 
≥25.
Adjusted weight calculation:
Ideal weight (kg) = (((Height (cm)/2.54) – 60) × 2.3) + 45.5
Adjusted weight (kg) = ((Actual weight – Ideal weight) × 0.40) + Ideal 
weight
If a patient with BMI of ≥ 25 is currently being dosed using actual weight, adjust 
dose with next planned treatment.
At the time of a dose modification for toxicity:
If the creatinine at the time of a dose modification is lower than the creatinine 
used to calculate the previous dose, use the previous (higher) creatinine; 
If the creatinine at the time of a dose modification is higher than the creatinine 
used to calculate the previous dose, use the current (higher) creatinine.  This will 
ensure that the patient is actually receiving a dose reduction. 
Note that carboplatin dose will be recalculated if the subject has weight change of greater 
than or equal to 10% from baseline.

All subjects will be randomized using an IRT system.  Before the study is initiated, 
directions for the IRT will be provided to each site.  The site will contact the IRT within 
4 calendar days prior to or on the subject's Cycle 1 Day –2 to obtain a Screening (subject) 
number once the subject has signed the informed consent and a study-specific procedure 
has been performed (i.e., central laboratory samples drawn).  Once the screening number

All subjects will be randomized using an IRT system.  Before the study is initiated, the 
IRT user manual, which provides instruction on how to use the system via the web or 
phone, will be provided to each site.
Subjects who complete all Screening procedures and meet eligibility criteria may proceed 
to randomization.  Subject randomization will be stratified by:  LDH (≤ ULN versus 
> ULN), and gender; therefore a subject's baseline LDH value must be known prior to 
randomization and when accessing the IRT to perform the randomization transaction.
The site will contact the IRT to obtain a Screening (subject) number once the subject has

subject is not enrolled/randomized the reason for screen failure will be documented in the 
source document and in the eCRF.  If the subject meets all inclusion and none of the 
exclusion criteria, the site will access the system to randomize the subject.  The IRT will 
randomize subjects in a 1:1:1 ratio to one of the three treatment arms as follows:
●
Arm A:  veliparib in combination with carboplatin/etoposide followed by 
veliparib monotherapy
●
Arm B:  veliparib in combination with carboplatin/etoposide followed by 
placebo monotherapy

Subsection Phase 2
Subsection title and text previously read:
Phase 2
Subjects will be randomized in a 1:1:1 ratio to receive carboplatin, etoposide, placebo 
followed by placebo maintenance or carboplatin, etoposide, veliparib followed by either 
veliparib or placebo maintenance for at least 4 cycles of combination treatment, unless 
disease progression or unacceptable toxicity warrants earlier discontinuation from the 
treatment.  Subject whose status at the completion of the 4th cycle of combination therapy 
warrants, in the opinion of the investigator, continued combination treatment may receive 
up to two additional combination therapy cycles (e.g., up to a total of 6 cycles).  After the 
completion of combination therapy, subjects without evidence of disease progression by 
most recent scheduled radiographic assessment (CT) will receive veliparib at 400 mg BID 
or placebo continuous schedule in 21-day cycles, until disease progression or 
unacceptable toxicity.

The following are guidelines for dose reduction, delay and discontinuation of 
veliparib/placebo:
1.
Veliparib/placebo part of combination therapy will be discontinued if both 
carboplatin and etoposide are discontinued prior to the completion of the planned 
number of combination therapy cycles.
2.
For any subject who experiences Grade 3/4 toxicity which is not attributable to 
carboplatin/etoposide or the underlying disease, the Veliparib/placebo dose will be 
held until the toxicity resolves to Grade 1 or lower or to baseline if Grade 2 is 
present at the time of study entry.  Upon toxicity resolution re-start veliparib at a 
reduced dose level.

Two dose reductions are allowed:
a.
Combination treatment cycles:  For Dose Reduction 1, the dose of 
Veliparib/placebo will be reduced to next lower dose level (assigned dose 
level -1).  Veliparib/placebo may be reduced again (Dose Reduction 2, assigned 
dose level –2) due to toxicity (Table 16).  If further dose reductions are 
required, this should be discussed with the AbbVie Study Designated 
Physician.  All veliparib/placebo dose reductions within combination 
treatment cycles are permanent.  Veliparib/placebo cannot be dose-reduced 
below 40 mg BID.
b. Monotherapy cycles:  Dose Reduction 1 to 300 mg BID, Dose Reduction 2 to 
200 mg BID.  Subjects requiring dose reduction of veliparib/placebo to below 
200 mg BID will be discontinued from the treatment.
4.
Any ≥ Grade 2 event of seizure attributed to veliparib/placebo requires 
discontinuation of veliparib/placebo.
5.
Veliparib/placebo doses held will not affect the study calendar and will not be 
replaced.  If veliparib/placebo-related toxicity necessitates the delay in 
veliparib/placebo re-initiation beyond the scheduled start of the next combination 
treatment cycle, the start of the cycle should be delayed until veliparib/placebo can 
be restarted.  The AbbVie study designated physician may be contacted 
(Section 6.6) for subjects who require more than a 2-week delay in the re-initiation 
of the next cycle.

If a subject experiences an adverse event attributable to carboplatin or etoposide, 
carboplatin or etoposide may either be held or dose reduced for that cycle.  At the 
Investigator's discretion, carboplatin and etoposide administration may continue as 
scheduled.
If a dose reduction or delay is required for carboplatin and/or etoposide, the Investigator 
should follow procedures as defined in the locally approved product label or applicable 
Summary of Product Characteristics (SmPC).  Section 5.7.2.1 outlines suggested dose

reductions for carboplatin/etoposide if above information is not available.  PD and/or PK 
samples will not be drawn during carboplatin and/or etoposide dose delays.  If the 
Investigator considers an event attributable to carboplatin and/or etoposide and not 
veliparib, the Investigator may consider reducing the dose of both agents.
All toxicity will be graded by the National Cancer Institute Common Terminology 
Criteria for Adverse Events version 4.0 (CTCAE).  All carboplatin and/or etoposide 
dose reductions are permanent.  Re-escalation of the dose of therapy is not allowed.  
All toxicities should have resolved to grade 1 or less prior to initiation of a new cycle of 
therapy, with the exception of anemia, alopecia, neuropathy, and non-treatment related 
clinically insignificant laboratory abnormalities.
If chemotherapy must be withheld due to hematologic toxicity, CBC and platelet counts 
should be obtained weekly until the counts reach the lower limits for treatment as 
outlined.  The treatment schedule will then proceed in the usual sequence.
If toxicity precludes the initiation of the dosing of carboplatin/etoposide in the cycle, and 
veliparib doses on Days –2 and –1 of the cycle have already been administered, veliparib 
should be administered again once the toxicity resolves for two days prior to 
carboplatin/etoposide dosing.

Section 5.7.2.1  Guidelines for Carboplatin and Etoposide Dose Reductions and 
Delays
Previously read:
The below guidelines are suggested, unless described as mandatory.  If a dose reduction 
or delay is required for carboplatin and/or etoposide, the Investigator should follow 
procedures according to institutional guidelines, the locally approved product label, local 
practice, or applicable SmPC.  If the Investigator considers an event attributable to 
carboplatin and/or etoposide, the Investigator may consider reducing carboplatin and/or 
etoposide, but not veliparib/placebo.  Suggested guidelines for dose reduction, delay, and 
discontinuation are included in Table 19 (if locally approved product label, local standard 
of care guideline or applicable SmPC for carboplatin/etoposide combination 
chemotherapy are not available).
Hematologic Toxicity
Neutropenia or Febrile Neutropenia
For febrile neutropenia with absolute neutrophil count (ANC) < 500/mm3 and a single 
temperature of > 38.3°C (101°F) or a sustained temperature of ≥ 38°C (100.4°F) for more 
than one hour, requiring intravenous antibiotics, the doses of both carboplatin and 
etoposide drugs should be reduced to the next lower dose level for all subsequent cycles 
of chemotherapy (Table 14).  Implement dose reductions 1 and 2 for first and second 
episodes, respectively, as outlined in Table 19.  Consider initiating prophylactic 
neutrophil growth factors (e.g., G-CSF) after the first episode.  If ANC counts do not 
recover within 3 weeks, discontinue all protocol therapy.
For treatment delays of more than 7 days due to neutropenia, carboplatin and etoposide 
should be dose-reduced to next lower dose level for all subsequent cycles of 
chemotherapy, as outlined in Table 19.
For nadir neutropenia in the absence of fever or with fever that is successfully treated by 
oral antibiotics, there will be no dose adjustment.

Veliparib
M14-361 Protocol Amendment 5
EudraCT 2014-001764-35
242
ANC must be ≥ 1,500/mm3 on Day 1 of each cycle (mandatory).  If the counts are lower 
than the limit, then dosing of all drugs (carboplatin, etoposide and veliparib) should be 
delayed until recovery to the required ANC.
If the subject experiences fever with neutropenia, then neutrophil growth factors 
(e.g., G-CSF) should be given based on local standard of care guidelines, ASCO or 
NCCN guidelines.  
Platelets
For Grade 4 nadir platelet count decrease (thrombocytopenia) (platelets < 25,000 mm3), 
the dose of both carboplatin and etoposide should be reduced to next lower dose level 
from the previous dose for all subsequent cycles of chemotherapy.  Implement dose 
reductions 1 and 2 for the first and second episodes, respectively as outlined in Table 19.  
If counts do not recover within 3 weeks, discontinue all protocol therapy.
Platelet count must be > 100,000/mm3 on Day 1 of each cycle.  Doses or all drugs 
(carboplatin, etoposide and veliparib) should be delayed until platelet count recovers to 
> 100,000/mm3.
Anemia
No dose reductions will be made for anemia.  Subjects should be supported per the 
treating physician's discretion.  The use of RBC transfusions for anemia will be allowed 
as clinically indicated and as per local standard of care or current NCCN guidelines.  The 
use of growth factors for anemia is not permitted during Phase 1 Cycle 1.
If more than two dose modifications of carboplatin and etoposide are required for 
hematologic toxicity, e.g., in cases where an additional dose modification is needed for a 
toxicity which was not observed earlier, please consult the Study Designated Physician.

antagonists should be used).  For vomiting Grade ≥ 3, consider hospital admission and/or 
use of aprepitant, if possible.  Nausea/vomiting should have resolved to Grade 1 or less 
prior to initiation of next treatment cycle.  Do not modify carboplatin and/or etoposide 
doses due to nausea/vomiting.
*
Aprepitant, when given once daily for 14 days as a 100 mg capsule with an oral contraceptive containing 35 mcg of 
ethinyl estradiol and 1 mg of norethindrone, decreased the AUC of ethinyl estradiol by 43% and decreased the 
AUC of norethindrone by 8%.  Women of childbearing potential using pregnancy contraception that includes 
ethinyl estradiol should not receive Aprepitant for the treatment of nausea/delayed emesis.  Subjects may change to 
a different method of contraception if they wish to use Aprepitant.
Hepatic Toxicity
For bilirubin > 1.5 – 3.0 × ULN, not attributable to underlying disease, reduce the dose of 
etoposide to 50 mg/m2.  For bilirubin > 3 – 5 × ULN reduce the dose of etoposide to 
30 mg/m2.  For bilirubin > 5 × ULN hold etoposide or hold all treatment if starting the 
next treatment cycle.  When bilirubin resolves to ≤ 5 × ULN, treatment can be resumed, 
with etoposide dose to 30 mg/m2.  If bilirubin does not improve to ≤ 5 × ULN within 
3 weeks of first occurrence, discontinue protocol therapy.
Other Grade 2/4 Non-Hematologic Toxicity
Other non-hematologic Grade 3/4 toxicity should be managed as per local SmPC 
guidelines and institutional standard practices.

Per local SmPC/institution guidelines
Per local SmPC/institution guidelines
Has been changed to read:
The below guidelines are suggested, unless described as mandatory.  If a dose reduction 
or delay is required for carboplatin and/or etoposide, the Investigator should follow 
procedures according to institutional guidelines, the locally approved product label, local 
practice, or applicable SmPC.  If the Investigator considers an event attributable to 
carboplatin and/or etoposide, the Investigator may consider reducing carboplatin and/or 
etoposide, but not veliparib/placebo.  Suggested guidelines for dose reduction, delay, and 
discontinuation are included in Table 16 and Table 19 (if locally approved product label,

local standard of care guideline or applicable SmPC for carboplatin/etoposide 
combination chemotherapy are not available).
All carboplatin and/or etoposide dose reductions are permanent.  Re-escalation of the dose 
of therapy is not allowed.  All toxicities should have resolved to grade 1 or less prior to 
initiation of a new cycle of therapy, with the exception of anemia, alopecia, neuropathy, 
and non-treatment related clinically insignificant laboratory abnormalities.
If toxicity precludes the initiation of the dosing of carboplatin/etoposide in the cycle, and 
veliparib doses on Days –2 and –1 of the cycle have already been administered, veliparib 
should be administered again once the toxicity resolves for two days prior to 
carboplatin/etoposide dosing.  In such a case, a new supply of veliparib/placebo is to be 
dispensed, and Day –2 and Day –1 are to be repeated for that cycle.
For Phase 1 ONLY:  PD and/or PK samples will not be drawn during carboplatin and/or 
etoposide dose delays.  If the Investigator considers an event attributable to carboplatin 
and/or etoposide and not veliparib, the Investigator may consider reducing the dose of 
both agents.
5.7.2.1.1
Hematologic Toxicity
If chemotherapy must be withheld due to hematologic toxicity, CBC and platelet counts
should be obtained weekly via central labs (if done locally, sample MUST be split for 
central lab) until the counts reach the lower limits for treatment as outlined.  The 
treatment schedule will then proceed in the usual sequence.
Neutropenia or Febrile Neutropenia
For febrile neutropenia with absolute neutrophil count (ANC) < 500/mm3 and a single 
temperature of > 38.3°C (101°F) or a sustained temperature of ≥ 38°C (100.4°F) for more 
than one hour, requiring intravenous antibiotics:

a.
Doses of both carboplatin and etoposide drugs should be reduced to the next lower 
dose level for all subsequent cycles of chemotherapy.  Suggested dose reduction 
levels are outlined in Table 14.
b. Implement dose reductions, as outlined in Table 19.
c.
Initiate prophylactic neutrophil growth factors (e.g., G-CSF) after the first episode 
and in accordance with local SOC practices, ASCO or NCCN guidelines.
d. If ANC counts do not recover within 3 weeks, discontinue all protocol therapy.
For treatment delays of more than 7 days due to neutropenia, carboplatin and etoposide 
should be dose-reduced to next lower dose level for all subsequent cycles of 
chemotherapy, as outlined in Table 19.
For nadir neutropenia in the absence of fever or with fever that is successfully treated by 
oral antibiotics, there will be no dose adjustment. 
ANC must be ≥ 1,500/mm3 on Day 1 of each cycle (mandatory).  If the ANC is lower 
than 1,500/mm3, then dosing of all drugs (carboplatin, etoposide and veliparib) will be 
delayed until recovery to the required ANC.
Platelets
For Grade 4 nadir platelet count decrease (thrombocytopenia) (platelets < 25,000 mm3), 
the dose of both carboplatin and etoposide should be reduced to next lower dose level 
from the previous dose for all subsequent cycles of chemotherapy.  Implement dose 
reductions 1 and 2 for the first and second episodes, respectively as outlined in Table 19.  
If counts do not recover within 3 weeks, discontinue all protocol therapy.
Platelet count must be > 100,000/mm3 on Day 1 of each cycle (mandatory).  Doses or all 
drugs (carboplatin, etoposide and veliparib) should be delayed until platelet count 
recovers to > 100,000/mm3.

Anemia
No dose reductions will be made for anemia.  Subjects should be supported per the 
treating physician's discretion.  The use of RBC transfusions for anemia will be allowed 
as clinically indicated and as per local standard of care or current NCCN guidelines.  The 
use of growth factors for anemia is not permitted during Phase 1 Cycle 1.
If more than two dose modifications of carboplatin and etoposide are required for 
hematologic toxicity, e.g., in cases where an additional dose modification is needed for a 
toxicity which was not observed earlier, please consult the AbbVie TA MD.
