SYNOPSIS 
Title of Study:  A Phase 1, Open-Label Study to Assess the Effects of Talazoparib on Cardiac 
Repolarization in Patients With Advanced Solid Tumors 
Protocol Identifier:  MDV3800-14 
Phase of Development:  1 
Number of Patients:  At least 30 patients 
Study Centers:  Approximately 12 (United States) 
Study Objectives: 
Primary: 
• To evaluate the effect of talazoparib on cardiac repolarization in patients with advanced solid tumors 
by assessing the corrected QT interval (QTc) 
• To assess the relationship between plasma talazoparib concentrations and the QTc 
Secondary: 
• To evaluate the safety and tolerability of talazoparib 
• To evaluate the effect of talazoparib on non-QT interval electrocardiogram (ECG) parameters (heart 
rate, RR, PR, QRS intervals, and ECG morphology) 
• To evaluate the pharmacokinetics (PK) of talazoparib 
Methods:  This is a phase 1, open-label safety study of talazoparib (also known as MDV3800, BMN 673), 
a poly(ADP-ribose) polymerase (PARP) inhibitor in development for the treatment of a variety of human 
cancers.  This study is designed to evaluate the effects of talazoparib on cardiac repolarization in at least 
30 patients with advanced solid tumors with no available standard treatment options.  Eligible patients will 
have continuous 12-lead ECG recordings at baseline (day -1); time-matched PK samples and continuous 
ECG recordings will be obtained at days 1, 2, and 22.  Patients will fast for at least 6 hours before and 
2 hours after the dose on days 1 and 22.   
On day -1, patients will have continuous 12-lead ECG recording, starting at time 0 (baseline, corresponding 
to the dosing time on day 1) for 6 hours.  On day 1, continuous 12-lead ECG recording will start 45 minutes 
before administration of talazoparib 1 mg at time 0, and continue through 6 hours postdose.  Blood samples 
for PK will be collected predose and at 1, 2, 4, and 6 hours postdose.  On day 2, a 30-minute continuous 
12-lead ECG recording and a blood sample for PK will be obtained before the day 2 dose of talazoparib.   
On days 3 to 21, talazoparib at 1 mg/day every day will be self-administered orally.  On days 8 and 15, 
patients will return for general assessments.   
On day 22, patients will return for steady-state continuous 12-lead ECG recordings, starting 45 minutes 
before the dose of talazoparib, and continuing for 6 hours postdose.  PK samples will be collected predose 
and at 1, 2, 4, and 6 hours postdose.   
ECG data from continuous 12-lead ECG recordings will be submitted for independent central review.  After 
reviewing for data quality, triplicate 10-second ECGs will be extracted from a 5-minute extraction window at 
each planned time point, beginning 15 minutes before each PK collection time point.  ECG recordings will 
be analyzed for measurement of RR, PR, QRS, and QT intervals and evaluation of ECG morphology.   
Study periods include screening, baseline (day -1), a 22-day treatment period, and safety follow-up.  Safety 
follow-up will occur approximately 30 days after the last dose of study drug or before initiation of a new 
antineoplastic therapy, whichever occurs first.  For further talazoparib treatment, patients must enroll and 
initiate continued talazoparib treatment in a separate open-label extension study within 30 days after the last 
dose of study drug, and in this case, safety follow-up will be omitted and an ECG will be obtained at the time 
of enrollment in the open-label extension study.

Study Assessments:   
Continuous ECGs will be collected on days -1, 1, 2, and 22; single ECGs will be collected at screening and 
safety follow-up.  PK samples will be collected on days 1, 2, and 22.  Other general and laboratory 
assessments will be performed at screening; days -1, 1, 2, 8, 15, and 22; and safety follow-up according to 
the schedules of activities.  Safety will be assessed by adverse events, physical examinations, vital signs, 
ECGs, and clinical laboratory tests.   
No efficacy assessments will be performed for this study.  Disease assessments will be performed according 
to the standard of care at the study site.   
Study Schematic:   
  
[1] Safety follow-up will be omitted for patients who enroll and initiate continued talazoparib treatment within 30 days 
in the open-label extension study; an ECG will be obtained at the time of enrollment in the open-label extension 
study.   
Key Eligibility Criteria:   
Patients must have histologically confirmed advanced solid tumors with no available standard treatment 
options.  The Eastern Cooperative Oncology Group (ECOG) performance status score must be ≤ 2 and 
estimated life expectancy must be ≥ 3 months.   
Test Product, Dose, and Mode of Administration: 
Talazoparib is provided as the 4-methylbenzenesulfonate (tosylate) salt and has the chemical name (8S,9R) 
5-fluoro-8-(4-fluorophenyl)-2,7,8,9-tetrahydro-9-(1-methyl-1H-1,2,4-triazol-5-yl)-3H-
pyrido[4,3,2-de]phthalazin-3-one.   
The drug product is a capsule containing talazoparib tosylate and silicified microcrystalline cellulose.  The 
capsules for each dose strength will be provided in dose-specific colors.   
Talazoparib 1 mg will be self-administered orally once daily at approximately the same time each day.  
Talazoparib capsules will be swallowed whole with a glass of water.  Patients will fast for at least 6 hours 
before and 2 hours after the dose on days 1 and 22.  Patients may resume eating after the 2-hour postdose PK 
sample is collected.  On other days, talazoparib may be taken with or without food.   
Reference Therapy, Dose, and Mode of Administration: 
Not applicable.   
Duration of Treatment: 
Talazoparib treatment will continue through day 22 in this study.  For further talazoparib treatment, patients 
must enroll and initiate continued talazoparib treatment in a separate open-label extension study within 
30 days after the last dose of talazoparib.  Dose modification guidelines must be followed for managing 
adverse events as described in Section 8.2.1.  Study drug treatment may be discontinued for disease 
progression based on investigator assessment.

Statistical Methods: 
Safety Analyses:   
All safety analyses will be performed using the safety population, defined as all patients who receive any 
amount of talazoparib.  The safety of talazoparib will be evaluated by the analysis of incidence of serious and 
nonserious adverse events, severity of adverse events, incidence of dose modifications and of permanent 
treatment discontinuation due to adverse events, and incidence of new clinically significant changes in vital 
signs, ECGs, and clinical laboratory values.  Drug exposure will be summarized using descriptive statistics.   
Adverse events will be coded to preferred term and system organ class using the Medical Dictionary for 
Regulatory Activities (MedDRA) and classified by severity using the National Cancer Institute Common 
Terminology Criteria for Adverse Events (CTCAE), version 4.  The number and percentage of patients with 
adverse events will be presented by MedDRA system organ class and preferred term, relationship to study 
treatment, severity, seriousness, and outcome (eg, leading to permanent treatment discontinuation).   
Treatment-emergent safety data will be collected from day 1 (the first dose of study drug) through 
approximately 30 days after the last dose of study drug, before initiation of a new antineoplastic therapy, or 
enrollment in the open-label extension study, whichever occurs first.   
Laboratory values will be classified by severity using the CTCAE.  Laboratory shift tables of baseline results 
to each subsequent visit will be produced as appropriate.   
ECG Analyses:  The primary endpoints are to evaluate the effects of talazoparib on Fridericia’s corrected QT 
interval (QTcF); and to evaluate the relationship between the plasma concentration of talazoparib and the 
change from baseline in QTc, corrected for heart rate based on Fridericia’s correction formula (ΔQTcF).  
Bazett’s correction formula (ΔQTcB) will also be evaluated.  Changes from time-matched baseline 
measurements will be calculated and data will be summarized in tabular and graphic formats for each study 
visit.  Assessments include absolute QTc prolongation with QTc > 450 msec, > 480 msec, and > 500 msec 
and change from baseline in QTc with QTc increase > 30 msec and > 60 msec.  The means of each 
measurement of RR, PR, QRS, and QT intervals will be utilized for statistical analyses.  Heart rate will be 
used to assess QTc endpoints.   
ECG morphology and changes from baseline for each planned postbaseline time point will be summarized 
for all patients.  The proportion of patients with any postbaseline change in ECG morphology and the 
proportion of patients with each type of abnormality will also be summarized.   
PK Analyses:   
Summary data of plasma talazoparib concentrations will be presented in tabular and graphic formats for each 
time point.  PK parameters such as time to maximum concentration (Tmax), maximum plasma concentration 
(Cmax), and area under the concentration-time curve (AUC) on days 1 and 22 will be calculated.  In addition, 
the PK data from this study will be combined with PK data from other studies to define a population PK 
model, which will be reported separately.   
PK-Pharmacodynamic Analyses: 
The correlation between changes in ECG interval measurements from time-matched baseline and the plasma 
talazoparib concentration will be investigated using a linear mixed-effects model.   
Efficacy Analyses:   
No efficacy analysis is planned in this study.   
Sample Size Considerations:   
A sample size of at least 30 evaluable patients will provide 80% power to reject the null hypothesis if the 
mean change from baseline in QTcF is ≥ 10 msec with a 95% one-sided alpha, assuming a standard deviation 
of 20 msec.  Patients will be enrolled until 30 patients complete day 22, miss ≤ 5 consecutive doses of study 
drug, have technically adequate ECG recordings, and have at least 80% of specified PK samples collected 
representing all 3 days of observation (days 1, 2, and 22).

1 INTRODUCTION 
1.1 
Background 
Talazoparib (also known as MDV3800, BMN 673) is a potent, orally bioavailable, small 
molecule poly(ADP-ribose) polymerase (PARP) inhibitor in development for the treatment 
of a variety of human cancers.  PARP inhibitors including talazoparib exert cytotoxic effects 
by 2 mechanisms:  inhibition of PARP1 and PARP2 enzyme activity, and PARP trapping, 
a process in which PARP protein bound to a PARP inhibitor does not readily dissociate from 
DNA, preventing DNA repair, replication, and transcription (Murai et al, 2012).  
Single-agent talazoparib has demonstrated potent antitumor effects in human cancer cell lines 
harboring gene mutations that compromise DNA repair, as well as in mouse tumor xenograft 
models (Murai et al, 2014; Shen et al, 2013; Cardnell et al, 2013).  Antitumor effects have 
also been observed in phase 1 studies of talazoparib monotherapy in patients with cancer.   
This cardiac safety study will evaluate the effects of talazoparib on cardiac 
electrophysiology, in particular cardiac repolarization as assessed by the corrected QT 
interval (QTc).   
1.2 
Summary of Relevant Clinical Experience With Talazoparib 
Approximately 319 patients have received talazoparib in company-sponsored studies as of 
30 Nov 2015, including 3 studies in solid tumors and 1 in hematologic malignancies.  Studies 
include a phase 1 study (PRP-001) in advanced solid tumors, a phase 2 study (673-201, 
ABRAZO) in advanced breast cancer, and a phase 3 study (673-301, EMBRACA) in locally 
advanced and/or metastatic breast cancer.   
1.2.1 
Efficacy 
PRP-001 is a phase 1, open-label, safety, pharmacokinetics (PK), and dose-escalation 
(0.025-1.1 mg/day) and expansion (1 mg/day) study of talazoparib monotherapy 
in 110 patients with advanced or recurrent solid tumors with DNA repair deficiencies.  As of 
30 Nov 2015, objective responses (complete response, partial response) per Response 
Evaluation Criteria in Solid Tumors, version 1.1 (RECIST 1.1) were observed in patients 
with breast (8 of 18 [44.4%]), ovarian/primary peritoneal (12 of 25 [48%]), and pancreatic 
(2 of 13 [15.4%]) cancers with deleterious germline breast cancer susceptibility gene 
(BRCA) mutations.  Clinical benefit (complete response, partial response, or stable disease 
≥ 24 weeks) was observed in 13 of 18 patients (72.2%), 19 of 25 patients (76%), and 4 of 
13 patients (30.8%), respectively.  In patients with small cell lung cancer, objective responses 
were observed in 2 of 23 patients (8.7%) and clinical benefit reported in 6 of 23 patients 
(26.1%).

Safety 
The safety of talazoparib is based on phase 1 and 2 studies in patients with advanced cancer.   
Aggregate safety data from 3 of the 5 company-sponsored clinical studies (phase 1 studies 
PRP-001 and PRP-002, and phase 2 study 673-201; 214 patients total; data as of 
30 Nov 2015) provide the basis for the most common treatment-emergent adverse events.  
The most common adverse events associated with talazoparib (> 20%) were 
myelosuppression (anemia, thrombocytopenia, neutropenia), gastrointestinal toxicity (nausea, 
diarrhea, vomiting), and fatigue.  The most common grade 3 or higher adverse events and 
serious adverse events were associated with myelosuppression.  A total of 25 of 214 patients 
had an adverse event that led to death (12 associated with malignancies, 3 disease 
progression, 2 each lung infection and pneumonia, and 1 each cardiorespiratory arrest, 
neutropenic sepsis, renal impairment, dyspnea, hypoxia, and respiratory failure).  Of these 
events, none was assessed as related to study drug.  Eight of 214 patients discontinued study 
drug due to an adverse event.   
In the ongoing phase 3 study 673-301, an adverse event of veno-occlusive disease of the liver 
leading to death was assessed as related to talazoparib by the investigator.   
Additional information on the clinical safety of talazoparib is provided in the talazoparib 
investigator brochure.   
1.2.3 
Pharmacokinetics 
The PK of talazoparib as a single agent was evaluated in 142 adult patients with cancer, 
including 109 patients with solid tumors (PRP-001) and 33 with hematologic malignancies 
(PRP-002).  Doses of 0.025 mg to 2 mg were administered orally as a single dose or as 
once daily doses.  This dose range bracketed the 1 mg/day dose used in ongoing safety and 
efficacy studies, and provided a framework for assessing dose linearity.  As the PK of 
talazoparib was similar in patients with solid tumors and hematologic malignancies, and no 
differences were apparent between males and females, the results are summarized 
collectively.   
Oral absorption of talazoparib was rapid and independent of dose after administration of 
single or once-daily doses.  Peak talazoparib concentrations were generally reached 
approximately 1 to 8 hours postdose.  Exposure increased approximately dose-proportionally 
with increasing doses.  At 1 mg/day, the mean half-life was approximately 2 days; the mean 
apparent volume of distribution was 415 L, indicating extensive extravascular distribution.  
Steady state was reached in approximately 2 to 3 weeks with daily administration.   
Apparent oral clearance (CL/F) of talazoparib appeared to be dose linear, with a mean CL/F 
across doses of approximately 5 L/h.  Renal excretion was a major elimination pathway for 
unchanged parent talazoparib.  Following oral administration, 44% to 90.6% of the dose was 
recovered in urine as unchanged parent drug over 24 hours at steady state for doses up to 
1 mg/day.  Mean renal clearance ranged from 1.38 L/h to 4.96 L/h, independent of dose, 
suggesting linear urinary elimination kinetics.

Page 11 of 58 
Following repeated administration at 1 mg/day, talazoparib accumulated approximately 
2.4-fold relative to a single dose.  At steady state, the mean maximum plasma concentration 
(Cmax) was 21.0 ng/mL, the mean plasma trough concentration (Cmin) was 3.72 ng/mL, and 
the mean area under the concentration-time curve (AUC) was 202 ng●h/mL.   
PK data from a food-effect study showed that food had no effect on the extent of absorption 
of talazoparib (AUC), but decreased the rate of absorption (Cmax was 46% lower and time to 
Cmax [Tmax] was 2.63 hours later); however this reduction in the rate of absorption following 
a single dose is not clinically relevant because talazoparib accumulates 2.4-fold at steady 
state after 1 mg once-daily dosing.  Furthermore, in nonclinical pharmacology studies, AUC 
or Cmin appeared to drive efficacy, not Cmax; therefore, talazoparib can be taken with or 
without food.  Talazoparib is being administered without regard to food in ongoing safety 
and efficacy studies.   
A preliminary population PK analysis using data from patients in studies PRP-001 and 
PRP-002 assessed the effects of renal function on the PK of talazoparib.  In patients with 
moderate renal impairment (creatinine clearance [CLCR] 30-59 mL/min), the talazoparib 
CL/F was decreased by 44% from normal, resulting in higher talazoparib exposure.   
The effects of hepatic impairment on talazoparib PK have not been studied.   
The potential for talazoparib to affect the PK of other drugs was assessed through in vitro 
experiments and is described in Section 1.3.2.  Additional information on the PK of 
talazoparib is provided in the investigator brochure.   
1.3 
Summary of Relevant Nonclinical Experience With Talazoparib 
1.3.1 
Nonclinical Pharmacology of Talazoparib 
The cytotoxic activity of talazoparib was demonstrated in cell culture, and antitumor effects 
were demonstrated in mouse xenograft models.   
In cell-free enzyme assays, talazoparib inhibited PARP1 and PARP2 catalytic activity 
(Wang et al, 2016).  Talazoparib was approximately 3.4- to 8.3-fold more potent than other 
PARP inhibitors in clinical development (veliparib, rucaparib, olaparib) in inhibiting PARP1 
catalytic activity (Shen et al, 2013).  In addition, talazoparib was approximately 40-fold more 
potent than olaparib in stimulating the formation of stable PARP1-DNA complexes 
(Murai et al, 2014).   
In tissue culture studies, talazoparib was cytotoxic to cancer cell lines harboring gene 
mutations that compromise DNA repair pathways, including MX-1 (BRCA1-mutant) and 
MDA-MB-468 (PTEN-mutant) mammary cancer cells, LNCaP (PTEN- and ATM-mutant) 
and PC-3 (PTEN-mutant) prostate cancer cells, and HCT-116 (MLH-1-mutant) colorectal 
tumor cells.  The half-maximal inhibitory concentration (IC50) values of talazoparib in these 
cancer cell lines were in the single-digit nanomolar or subnanomolar range; in contrast, the 
IC50 values of talazoparib in MRC-5 normal human primary lung cancer cells and other 
tumor cell lines without reported DNA repair-related mutations were higher (250 nM to

> 1000 nM).  The talazoparib IC50 for growth inhibition of Capan-1 human pancreatic cancer 
cells (BRCA2-deficient) was 50- to over 2000-fold lower than the other PARP inhibitors 
tested (Shen et al, 2013).  The higher potency of talazoparib relative to the other PARP 
inhibitors is thought to be due to the more potent PARP trapping activity seen with 
talazoparib as opposed to inhibition of PARP catalytic activity (Shen et al, 2015).   
Consistent with its antitumor effects in tissue culture, talazoparib demonstrated potent 
antitumor activity in mouse xenograft models of small cell lung cancer and breast cancer 
(Cardnell et al, 2013; Shen et al, 2013).   
Additional information on the nonclinical pharmacology of talazoparib is provided in the 
talazoparib investigator brochure.   
1.3.2 
Nonclinical PK and Metabolism 
PK studies in rats and dogs show that talazoparib oral bioavailability was > 43% in rats and 
> 51% in dogs.  A Good Laboratory Practice (GLP) study in dogs demonstrated that the 
capsule formulation used in clinical studies is approximately 2-fold more bioavailable than 
the suspension formulation used in nonclinical studies.  In general, talazoparib displays 
greater than or approximately dose-proportional increases in exposure in rats and dogs with 
no evidence of sex differences.   
Studies of [14C]-talazoparib in rats and dogs indicate rapid absorption, wide distribution 
(greater than total body water), and nearly complete elimination of drug substance (> 90%) 
by 7 days.  Fecal elimination was the main route of elimination in both species, and renal 
excretion was moderate (21-26%).  In a study in rats, [14C]-talazoparib was widely 
distributed, reaching maximum levels 1 to 4 hours postdose.  Excluding the gastrointestinal 
tract, the highest radioactivity levels were observed in liver and kidney (and the eye uveal 
tract in albino rats).  Tissue radioactivity levels were greater than blood levels in the target 
organs of talazoparib toxicity (bone marrow, spleen, and thymus) through 7 days.  Metabolic 
profiling of plasma, urine, and feces samples indicated that [14C]-talazoparib is largely 
cleared via excretion of unchanged parent drug and metabolized to a minor extent via 
oxidation and dehydrogenation.   
In vitro metabolism studies in rat, dog, and human hepatic microsomes demonstrated that 
[14C]-talazoparib has high metabolic stability (> 90%) over 2 hours.  A minimal extent or 
a lack of metabolism for [14C]-talazoparib was observed in the presence of freshly isolated 
mouse, rat, dog, and human hepatocytes or cryopreserved human hepatocytes.  Talazoparib 
does not appear to be a substrate of any major cytochrome P450 (CYP450) metabolizing 
enzyme.   
Mean binding to human plasma proteins is 78.7%; therefore, it is unlikely that talazoparib 
will demonstrate clinically significant drug-drug interactions related to displacement from 
plasma protein binding sites.  At therapeutic exposures, talazoparib does not markedly induce 
or inhibit CYP450 enzymes.  Therefore, it is unlikely that talazoparib will demonstrate 
clinically significant CYP450 inhibition- or induction-based drug-drug interactions when 
coadministered with corresponding substrates.  At therapeutic exposures, talazoparib does

not markedly induce or inhibit any transporters.  Therefore, it is unlikely that talazoparib will 
demonstrate clinically significant drug transporter inhibition-based drug–drug interactions 
when coadministered with corresponding substrates.   
Because talazoparib is a substrate for P-glycoprotein (P-gp) and breast cancer resistance 
protein (BCRP), plasma talazoparib concentrations may increase or decrease when 
coadministered with P-gp or BCRP inhibitors or inducers, respectively.  Guidelines for 
concomitant use of talazoparib inhibitors or inducers of P-gp or inhibitors of BCRP are 
provided in Section 7.3.   
Additional information on the nonclinical PK and drug metabolism of talazoparib is provided 
in the investigator brochure.   
1.3.3 
Nonclinical Toxicology 
Safety pharmacology, single- and repeat-dose toxicity, genotoxicity, embryo-fetal 
development, and in vitro phototoxicity studies were conducted to evaluate the nonclinical 
toxicology profile of talazoparib.  Repeat-dose toxicity/toxicokinetic studies were conducted 
with talazoparib utilizing the intended oral route of administration in mice, rats, and dogs.  A 
repeat-dose study with talazoparib was conducted in BALB/c nude mice to select doses and 
exposures for the mouse xenograft studies.   
Five-day, 28-day, and 13-week repeat-dose GLP toxicity and toxicokinetic studies with 
28-day recovery periods were conducted in the rat and dog.  The major findings are as 
follows:   
• 
Dose-dependent pancytopenia with bone marrow hypocellularity and depletion of 
lymphoid tissue in multiple organs was observed and considered possibly due to 
exaggerated pharmacology of talazoparib based on the higher (relative to baseline) 
poly(ADP-ribose) (index of PARP1/2 activity) tissue levels in these organs.  The 
hematologic findings were partially reversible and may be readily monitored in the 
clinic.  The toxicities that resulted in mortality in dogs (0.1 mg/kg/day) and some rats 
(1 mg/kg/day) occurred at AUC0-24 exposures that were > 0.8- and 4-fold higher, 
respectively, than the exposure at the recommended human dose of 1 mg/day.  The 
toxicities were mainly due to septicemia that resulted from the severe bone marrow 
and lymphoid depletion.   
• 
A dose-dependent increased incidence of gastrointestinal tract findings of 
apoptosis/necrosis in the stomach and duodenum was observed.  Additional findings 
at higher doses included reversible villous atrophy and increased apoptosis 
throughout the gastrointestinal tract, most notably in the small intestine.  
Gastrointestinal tract toxicities of enteropathy and villous atrophy caused mortality in 
rats at 3.0 mg/kg/day.  Exposures at 3.0 mg/kg/day are significantly higher than the 
exposures at the recommended human dose.

• 
Additional findings at the high dose (≥ 1 mg/kg/day) in the 5-day GLP study in rats 
included focal necrotic changes in the ovarian follicular atresia and hepatocyte 
necrosis of the liver.  These findings were not observed in the 28-day or 13-week 
repeat-dose studies in rats.   
• 
Atrophy and/or degenerative changes in testes and epididymis and effects on the 
seminiferous tubules were observed in rats and dogs; the severity correlated with both 
dose and duration of treatment.   
There were no talazoparib-related effects on respiratory or central nervous system parameters 
after a single oral administration to rats (safety pharmacology studies), or on cardiovascular 
parameters and electrocardiogram (ECG) evaluations after a repeat-dose oral administration 
in dogs (repeat-dose toxicity studies).  Talazoparib had no effect on ophthalmologic end 
points in rats or dogs in repeat-dose toxicity studies.  Talazoparib was not mutagenic in a 
bacterial reverse mutation assay, but consistent with the genomic instability of its primary 
pharmacology, was clastogenic in an in vitro chromosomal aberration assay and in an in vivo 
micronucleus assay, indicating the potential for genotoxicity in humans.  Talazoparib caused 
fetal malformations, structural variations, and death in an embryo-fetal development study in 
rats.  Based on an in vitro 3T3 neutral red uptake assay, which results in a high incidence of 
false positives, talazoparib is potentially phototoxic in humans.  In conclusion, the main 
nonclinical toxicologic findings were early hematologic changes, and subsequent bone 
marrow and lymphoid organ depletion; focal atrophy and degeneration of testes, epididymis, 
and seminiferous tubules; and dose-dependent apoptosis/necrosis in the gastrointestinal tract 
and liver after repeat-dose talazoparib.  These findings are consistent with the exaggerated 
pharmacology of talazoparib and its tissue exposure pattern.  Additional information on the 
toxicology of talazoparib is provided in the talazoparib investigator brochure.   
1.4 
Cardiac Safety of Talazoparib 
In vitro, talazoparib has an estimated IC50 for inhibition of hERG channels of > 100 μM 
whereas in humans taking 1 mg once daily the mean Cmax at steady state is 0.055 μM (free 
Cmax of 0.0117 μM), indicating low potential for significant inhibition.  In vivo, ECG 
evaluations were conducted in 28-day and 13-week toxicity studies in beagle dogs over a 
range of doses.  No talazoparib-related changes in PR, QRS, QT, QTc, or RR intervals, or 
heart rate were observed on days 3 or 24 of the dosing phase (28-day study) or day 90 of the 
dosing phase or day 26 of the recovery phase (13-week study).  No rhythm abnormalities or 
qualitative ECG changes were observed during qualitative assessment of the ECGs in either 
study.   
In phase 1 study PRP-001 (110 patients), ECGs were recorded at baseline, at 3 to 4 hours 
postdose on days 1 and 35 (dose-escalation phase) or at day 1 of cycle 2 (dose-expansion 
phase), and at the end of treatment (< 10 days after the last dose of talazoparib), if clinically 
indicated.  ECG interval data were collected retrospectively from these recordings.  Of the 
96 patients with ECG recordings at baseline and postbaseline based on draft data, 1 patient 
had a postbaseline QTcF (Fridericia’s corrected QT interval) > 500 msec; 1 had a 
postbaseline QTcF > 480 msec to ≤ 500 msec; and 9 (9.4%) had a postbaseline

QTcF > 450 msec to ≤ 480 msec.  One patient had an increase in QTcF from baseline 
> 60 msec and 6 (6.3%) had an increase in QTcF from baseline > 30 msec to ≤ 60 msec.   
These observations indicate that talazoparib has a low risk of QT prolongation or 
proarrhythmic effects.  This study will further assess the effects of talazoparib on cardiac 
electrophysiology.   
1.5 
Talazoparib Benefits and Risks Assessment 
The dose of talazoparib in this study, 1 mg/day, is supported by nonclinical studies and 
phase 1 studies in patients with advanced malignancies.  Antitumor activity has been 
observed, and warrants further exploration in a larger patient population.  The expected 
adverse events with talazoparib include myelosuppression, gastrointestinal toxicity, fatigue, 
and alopecia.  Hepatotoxicity, febrile neutropenia, and neutropenic sepsis are potential risks 
per the investigator brochure Section 7.  The activity of talazoparib is being evaluated in 
multiple indications.  The benefit-risk profile of talazoparib is not yet well characterized.

3 INVESTIGATIONAL PLAN 
3.1 
Overall Study Design and Plan:  Description 
This is a phase 1, open-label safety study of talazoparib, a PARP inhibitor in development for 
the treatment of a variety of human cancers.  This study is designed to evaluate the effects of 
talazoparib on cardiac repolarization in at least 30 patients with advanced solid tumors with 
no available standard treatment options.  Eligible patients will have continuous 12-lead ECG 
recordings at baseline (day -1); time-matched PK samples and continuous ECG recordings 
will be obtained at days 1, 2, and 22.  Patients will fast for at least 6 hours before and 2 hours 
after the dose on days 1 and 22.   
On day -1, patients will have continuous 12-lead ECG recording, starting at time 0 (baseline, 
corresponding to the dosing time on day 1) for 6 hours.  On day 1, continuous 12-lead ECG

recording will start 45 minutes before administration of talazoparib 1 mg at time 0, and 
continue through 6 hours postdose.  Blood samples for PK will be collected predose and at 1, 
2, 4, and 6 hours postdose.  On day 2, a 30-minute continuous 12-lead ECG recording and a 
blood sample for PK will be obtained before the day 2 dose of talazoparib.   
On days 3 to 21, talazoparib at 1 mg/day every day will be self-administered orally.  On 
days 8 and 15, patients will return for general assessments.   
On day 22, patients will return for steady-state continuous 12-lead ECG recordings, starting 
45 minutes before the dose of talazoparib, and continuing for 6 hours postdose.  PK samples 
will be collected predose and at 1, 2, 4, and 6 hours postdose.   
ECG data from continuous 12-lead ECG recordings will be submitted for independent central 
review.  After reviewing for data quality, triplicate 10-second ECGs will be extracted from a 
5-minute extraction window at each planned time point, beginning 15 minutes before each 
PK collection time point.  ECG recordings will be analyzed for measurement of RR, PR, 
QRS, and QT intervals and evaluation of ECG morphology.   
Study periods include screening, baseline (day -1), a 22-day treatment period, and safety 
follow-up.  Safety follow-up will occur approximately 30 days after the last dose of study 
drug or before initiation of a new antineoplastic therapy, whichever occurs first.  For further 
talazoparib treatment, patients must enroll and initiate continued talazoparib treatment in a 
separate open-label extension study within 30 days after the last dose of study drug, and in 
this case, safety follow-up will be omitted and an ECG will be obtained at the time of 
enrollment in the open-label extension study.

3.5 
Discussion of Study Design 
The maximum tolerated dose of talazoparib is 1 mg/day (de Bono et al, 2013) and is defined 
as the recommended human dose.  The talazoparib 1 mg/day dose is being used in this study 
and is currently being evaluated in ongoing studies in patients with breast cancer, as 
discussed in Section 1.  This study will assess the risk of QT prolongation with serial ECG 
recordings and time-matched PK measurements.  Supratherapeutic doses cannot be 
administered safely, so a traditional thorough QT study is not feasible.  Because talazoparib 
is clastogenic in vitro and in vivo, it is not possible to conduct the study in healthy 
volunteers.  Therefore, adult patients with advanced solid tumors, representative of the 
population being evaluated in current and planned phase 2 and 3 studies, will be enrolled.   
With chronic dosing at 1 mg/day, plasma talazoparib concentrations reach steady state in 
2 to 3 weeks, with about a 2.4-fold accumulation relative to a single dose.  Therefore, 
a 22-day dosing duration will allow most patients to reach steady-state concentrations of 
talazoparib.  ECG recordings will be obtained with time-matched PK samples over a wide 
range of plasma talazoparib concentrations, after both acute and chronic dosing.   
The primary endpoints are to evaluate the effects of talazoparib on QTcF and to evaluate the 
relationship between the plasma concentration of talazoparib and the change from baseline in 
QTc, corrected for heart rate based on the QTcF correction formula (∆QTcF).  Bazett’s 
correction formula (ΔQTcB) will also be evaluated.  Continuous ECG recordings will be 
obtained at baseline (day -1), and continuous ECG recordings and blood samples for PK will 
be obtained on days 1, 2, and 22 (steady state) to obtain ECG recordings over a range of 
plasma concentrations of talazoparib.  Patients will fast for at least 6 hours before and 
2 hours after the dose on days 1 and 22 to minimize the variability of Cmax.  For the PK-
pharmacodynamic (PD) analysis, a linear mixed effects modeling approach will be used to 
examine the relationship between the changes from baseline in QTc intervals (ΔQTcF and 
ΔQTcB) and plasma concentration of talazoparib.   
No tumor assessments or other efficacy measures will be collected in this study.  Disease 
assessments may be performed according to the standard of care at the study site.

ENROLLMENT AND STUDY PROCEDURES 
Study enrollment and procedures are summarized in the following subsections.  The study 
periods will include screening, treatment (baseline on day -1 and 22 days of treatment), and 
safety follow-up.  The timing of all study procedures is provided in the schedules of activities 
(Appendix 1, Appendix 2).  Signed informed consent must be obtained before performing 
any study-specific procedures.  The study manual contains the information needed for 
registering patient status (eg, assigning screening and enrollment numbers, indicating screen 
failure, and end of treatment).   
5.1 
Screening Period 
The screening period will be from day -29 through day -2.  For the purposes of this study, 
there will be no day 0.   
5.1.1 
Informed Consent 
Study site personnel must explain to potential study participants all aspects of the study, 
including all scheduled visits and activities.  Study site personnel must obtain signed 
informed consent before any study-specific procedures are conducted unless the procedures 
are part of routine standard of care, and must document the informed consent process in the 
patient’s source documents.   
The informed consent form may be signed before the 28-day screening period.   
5.1.2 
Screening Identification Numbers 
After obtaining signed informed consent, study site personnel will assign a screening 
identification (ID) number for each potential study participant per the study manual.   
For patients who provide informed consent and subsequently do not meet eligibility criteria 
or withdraw consent, study site personnel will document the screen failure or consent 
withdrawal in the patient’s source documents.  The documentation will include demographics 
and medical history, the reason for screen failure, the eligibility criteria reviewed, and 
procedures performed.

5.1.3 
Screening Procedures 
Screening procedures are listed in the schedule of activities in Appendix 1.  All procedures 
must be completed within 28 days before day -1 except as noted.   
The investigator will assess the eligibility of each patient.  All screening procedure results 
and relevant medical history must be available before eligibility can be determined.  All 
inclusion criteria must be met and none of the exclusion criteria may apply.  No eligibility 
waivers will be granted.   
After a patient is screened and the investigator determines the patient is eligible for 
enrollment, study site personnel will request that the sponsor or designee approve the 
enrollment.   
5.2 
Treatment Period 
5.2.1 
Treatment Period Visit Windows 
All treatment period visits have a visit window of ±3 days (ie, 3 days before or after the 
given day), except for days -1, 1, and 2.   
5.2.2 
Treatment Period Procedures 
5.2.2.1 
Enrollment 
Study site personnel should receive enrollment approval from the sponsor or designee before 
proceeding with enrollment.  An enrollment ID number will be assigned per the study 
manual.  This number will be used to identify the patient for the remainder of the study.  
Patients must initiate study treatment within 3 business days after enrollment approval.   
5.2.2.2 
Treatment Period Study Visit Procedures 
Day -1 is the day of baseline, and day 1 is the day of the first dose of study drug.   
Specified study procedures will be performed at each clinic visit according to the schedule of 
activities (Appendix 2).  The ECG, blood pressure, and PK collection schedule is as follows 
(Appendix 3): 
• 
Continuous ECG recordings are obtained by attaching the Holter monitor at the start 
of the collection time point on days -1, 1, 2, and 22.  Blood pressure (after supine for 
5 minutes) will be obtained 15 to 20 minutes before each PK collection time point.  
After blood pressure is obtained, the patient should remain supine for 10 to 
15 minutes (for continuous ECG recording) before blood samples for PK are 
collected.   
• 
On day -1 (baseline), ECG recording will start at time 0 (corresponding to the dosing 
time on day 1) and continue for 6 hours.

Page 22 of 58 
• 
Patients will fast for at least 6 hours before and 2 hours after the day 1 dose.   
• 
On day 1 (within 72 hours of time 0 on day -1, corresponding to the clock time of the 
first baseline ECG measurement), ECG recording will start at least 45 minutes before 
the first dose of study drug at time 0, and continue for 6 hours postdose.  Blood 
samples for PK will be collected immediately before the first dose of study drug and 
at 1, 2, 4, and 6 hours postdose.  Patients may resume eating after the 2-hour postdose 
PK sample is collected.   
• 
On day 2, at 24 hours after the first dose of study drug, ECG recording will start at 
least 30 minutes before time 0 and continue until the day 2 dose.  The day 2 dose 
should be taken at approximately the same clock time (within 1 hour of time 0) as the 
day 1 dose.  Blood samples for PK will be collected before the dose.   
• 
Patients will fast for at least 6 hours before and 2 hours after the day 22 dose.   
• 
On day 22, ECG recording will start at least 45 minutes before administration of the 
day 22 dose at time 0, and continue for 6 hours postdose.  The day 22 dose should be 
taken at approximately the same clock time (within 1 hour of time 0) as the day 1 
dose.  Patients may resume eating after the 2-hour postdose PK sample is collected.  
Blood samples for PK will be collected immediately before the dose of talazoparib 
and at 1, 2, 4, and 6 hours postdose.   
5.2.3 
Unscheduled Visit Procedures 
Unscheduled visits may be performed anytime to assess or follow up adverse events or at the 
request of the patient or investigator.  The date and reason for the unscheduled visit must be 
recorded in the source documentation.   
A review of adverse events and changes to concomitant medications or treatments (including 
herbal therapies) occurring since the previous visit should be performed at unscheduled 
visits.   
Unscheduled visit procedures are listed in Appendix 2.  Other study procedures may be 
performed as clinically appropriate.   
5.3 
Permanent Treatment Discontinuation 
Permanent treatment discontinuation is defined as cessation of study drug treatment 
administration.  After permanent discontinuation, safety follow-up will be per Section 5.4, 
unless the patient withdraws consent for further follow-up.   
Temporary treatment interruption (eg, due to an adverse event) is not considered permanent 
discontinuation.   
The primary reasons for which patients permanently discontinue study treatment are listed in 
Table 1.

Page 23 of 58 
Table 1: Primary Reasons for Permanent Treatment Discontinuation 
Reason 
Comment 
Adverse event or intercurrent illness 
Any intolerable adverse event that cannot be ameliorated by 
the use of adequate medical intervention or that in the opinion 
of the investigator or sponsor would lead to undue risk if 
study treatment were continued (eg, severe drug-induced liver 
injury [Section 8.2.1.1.1] or MDS/AML [Table 3]).  Refer to 
Section 8.3.1.  May or may not be related to disease 
progression.   
Disease progression 
Study drug treatment may be discontinued for disease 
progression based on investigator assessment.   
Administration of prohibited 
concomitant therapy 
Refer to Section 7.2.   
Patient decision 
Patients may permanently discontinue treatment anytime for 
any reason.   
Investigator decision 
Protocol treatment may be discontinued if the investigator 
considers it is in the patient’s best interest.  This category 
should be selected if adverse event, disease progression, or 
administration of prohibited concomitant therapy do not apply 
and the patient preferred to continue treatment.   
Major noncompliance with protocol 
The medical monitor or investigator may request permanent 
treatment discontinuation in the event of a major protocol 
deviation, lack of cooperation, or noncompliance.   
Loss to follow-up 
Refer to Section 5.5.   
Sponsor discontinuation of study 
The sponsor reserves the right to terminate the study anytime 
for any reason as described in Section 13.6.  The sponsor will 
terminate this study following completion of the study 
objectives, or earlier if deemed necessary.   
AML, acute myeloid leukemia; MDS, myelodysplastic syndrome.   
 
5.4 
Safety Follow-Up 
Safety follow-up will occur approximately 30 days after the last dose of study drug or before 
initiation of a new antineoplastic therapy, whichever occurs first.  For further talazoparib 
treatment, patients must enroll and initiate continued talazoparib treatment in a separate 
open-label extension study within 30 days after the last dose of study drug, and in this case, 
the safety follow-up will be omitted and an ECG will be obtained at the time of enrollment in 
the open-label extension study.   
In the event that a new antineoplastic therapy is initiated before safety follow-up occurs 
(eg, a physician not associated with protocol MDV3800-14 initiates the treatment, and study 
site personnel are not aware of the treatment until afterward), safety follow-up should be 
scheduled as soon as possible.   
Safety follow-up procedures are listed in Appendix 2.

Page 24 of 58 
If treatment is discontinued due to an adverse event or serious adverse event, the event(s) 
must be followed up as described in Section 8.3.9.   
For patients who refuse to come to the clinic for safety follow-up, telephone contact must be 
attempted and documented to review for adverse events through approximately 30 days after 
the last study drug treatment, before initiation of a new antineoplastic therapy, or enrollment 
in the open-label extension study, whichever occurs first.  If the patient does not respond to 
telephone calls, the procedures for loss to follow-up in Section 5.5 should be followed.   
5.5 
Loss to Follow-Up 
Every reasonable effort must be made to contact any patient apparently lost to follow-up 
during the course of the study to complete study-related assessments and record outstanding 
data.  Following unsuccessful telephone contact, the following should occur:   
• 
An effort to contact the patient by mail using a method that provides proof of receipt 
should be attempted.   
• 
Alternate contacts are permissible if the patient is not reachable (eg, primary care 
providers, referring physician, relatives).  
• 
Such efforts should be documented in the patient’s source documents.   
If all efforts fail to establish contact, the patient will be considered lost to follow-up.   
Patients who withdraw consent will be considered lost to follow-up for analysis purposes.

The label will vary depending on individual country requirements.  At minimum, each label 
typically provides the study protocol number, contents, directions for use and storage, 
clinical trial statement, sponsor name, batch/lot number, and product retest or expiration date.   
6.2.2 
Storage of Talazoparib 
The drug product should be stored safely and properly in accordance with the study drug 
label.   
6.2.3 
Directions for Administration of Talazoparib 
The daily dose of talazoparib is 1 mg given orally.   
Talazoparib will be administered at the study site on days 1, 2, and 22.  Patients will fast for 
at least 6 hours before and 2 hours after the dose on days 1 and 22.  Patients may resume 
eating after the 2-hour postdose PK sample is collected.  On other days, talazoparib may be 
taken with or without food.  The days 2 and 22 doses should be taken at approximately the 
same clock time (within 1 hour of time 0) as the day 1 dose.  On days 3 to 21, patients should 
self-administer talazoparib orally once daily at approximately the same time each morning.  
The capsules should be swallowed whole with a glass of water without chewing, dissolving, 
or opening them.   
Patients should not make up missed or vomited doses; dosing should resume on the next 
calendar day unless otherwise instructed.   
Dose modifications due to adverse events are described in Section 8.2.1.   
Talazoparib is considered a cytotoxic and clastogenic agent; precautions regarding 
appropriate secure storage and handling must be used by healthcare professionals, including 
personal protective clothing, disposable gloves, and equipment (Goodin et al, 2011).  Patients 
should be advised that oral anticancer agents are toxic substances and that (other than the 
patient) caregivers should always use gloves when handling the capsules.   
6.3 
Treatment Compliance 
Accountability for the study drug capsules will be performed to document compliance with 
the dosing regimen.  Patients will be asked to bring all used and unused study drug bottles to 
study visits.  Study site personnel must make reasonable efforts to obtain used and unused 
study drug bottles from patients who do not routinely return them at study site visits.  
Unreturned capsules will be considered to have been taken.

7.1 
Prior Medications 
All prior cancer treatments, other medications taken within 30 days before day -1, and any 
medications prescribed for chronic or intermittent use during the study, or dose adjustments 
of these medications, must be recorded on the case report form and in the patient’s source 
documents.   
7.2 
Concomitant Therapy 
Concomitant therapy (noninvestigational products) includes any concomitant medications 
(Section 7), blood transfusions, or radiotherapy used between day -1 and the end of 
treatment.   
Patients will be instructed to consult with the investigator before taking any additional 
medications (including over-the-counter medications).  Supportive medications may be 
provided prophylactically or therapeutically per investigator discretion, with the exception 
that granulocyte-colony stimulating factor (G-CSF) is only allowed in the rescue setting.  
Palliative radiation is allowed but the combination of radiation therapy and talazoparib has 
not been studied.   
Concomitant therapies will be assessed at all clinic visits and must be recorded on the 
appropriate case report form.  If the use of any medication during the study is due to 
an adverse event, the adverse event must be recorded on the adverse event case report form 
and in the patient’s source documents.   
Prohibited medications are described in Table 2.  Deviation from these guidelines should 
occur only if absolutely necessary for the well-being of the patient, and the medical monitor 
is to be notified to determine whether continued treatment with study drug is permitted.   
Study drug must be permanently discontinued upon initiation of any other antineoplastic 
therapy.  Patients who discontinue treatment due to initiation of such therapy will complete 
safety follow-up per Section 5.4.

drug treatment or who do not meet the criteria but who have abnormal liver tests are to be 
followed up according to the recommendations in this section.   
Study drug should be withheld for any liver test abnormality listed in Table 5.   
Table 5: Criteria for Temporary Withholding of Study Drug in Association With 
Liver Test Abnormalities 
Baseline AST or ALT Value 
Elevation 
≤ 3 × ULN 
> 5 × ULN (ALT or AST ≥ 3 × ULN with the presence of signs 
and symptoms consistent with acute hepatitis and/or eosinophilia

> 8 × ULN  
Baseline Total Bilirubin Value 
Elevation 
≤ 1.5 × ULN 
> 3 × ULN (> 5 × ULN in patients with a baseline total bilirubin 
value of > 1.5 × ULN and ≤ 3 × ULN [patients with Gilbert 
syndrome or for whom indirect bilirubin concentrations suggest 
an extrahepatic source of elevation]) 
For rechallenge, dose modification may be required per Table 4.   
ALT, alanine aminotransferase; AST, aspartate aminotransferase; ULN, upper limit of normal.   
 
Study drug should be withheld pending investigation of alternative causes of liver injury 
(Table 6).  When withholding study drug, follow-up should continue for possible 
drug-induced liver injury until the liver test abnormalities resolve to baseline grade.   
Rechallenge may be considered at a 1 dose level reduction per Table 4 if an alternative cause 
for the abnormal liver tests (ALT, AST, total bilirubin) is discovered and the laboratory 
abnormalities resolve to normal or baseline values.  The investigator and sponsor should 
discuss and agree with any decision to rechallenge.   
Following rechallenge, patients should be closely monitored for signs and symptoms of 
hepatitis and/or abnormal liver test results.  If signs or symptoms consistent with hepatitis 
recur or the withholding criteria in Table 5 are met after rechallenge, study drug treatment 
should be permanently discontinued.   
Rechallenge should not occur when the etiology of the liver test abnormalities is considered 
drug induced.

No alternative cause explains the combination of the above laboratory abnormalities; 
important alternative causes include, but are not limited to the following: 
x 
Hepatobiliary tract disease 
x 
Viral hepatitis (eg, hepatitis A/B/C/D/E, Epstein-Barr virus, cytomegalovirus, herpes 
simplex virus, varicella, toxoplasmosis, and parvovirus) 
x 
Congestive heart failure, hypotension, or any cause of hypoxia to the liver causing 
ischemia 
x 
Exposure to hepatotoxic agents/drugs or hepatotoxins, including herbal and dietary 
supplements, plants, and mushrooms 
x 
Alcoholic hepatitis 
x 
Nonalcoholic steatohepatitis (NASH) 
x 
Autoimmune hepatitis  
x 
Wilson disease and hemochromatosis 
x 
Alpha-1 antitrypsin deficiency  
If an alternative cause for hepatotoxicity is identified or less stringent conditions developed 
than those noted above, then it should be determined (based on the patient population and/or 
severity of the hepatotoxicity or event) whether study drug should be withheld or 
permanently discontinued as appropriate for the safety of the patient.  When study drug is 
temporarily withheld or permanently discontinued due to a potential drug-induced liver 
injury, a period of close observation is to commence until the liver test abnormalities return 
to baseline or normal values.  The evaluations listed in Table 7 should be performed.

As drug-induced liver injury is a diagnosis of exclusion, it is important to initiate 
investigation of alternative causes for abnormal liver tests, which may include consultation 
with a hepatologist.  The medical monitor should be contacted for questions regarding 
adequate follow-up tests.

Overdose Management 
The medical monitor must be contacted in the event of a study drug overdose.  An overdose 
is defined as any dose greater than the protocol-specified dose of talazoparib.  In the event of 
an overdose, treatment with study drug should be stopped and general supportive measures 
initiated, taking into consideration the mean half-life is 50 hours.  No antidote to overdose is 
known.   
All overdose events are to be reported within 24 hours of awareness by the study site 
according to Section 8.3.6 whether or not the overdose is associated with an adverse event.   
8.2.3 
Reproductive Considerations 
Female Patients 
Female patients of childbearing potential must have a negative pregnancy test at screening 
(serum tested centrally) and safety follow-up (urine or serum tested locally or using a 
centrally provided kit), and must avoid pregnancy during the study.  Urine pregnancy tests 
must have a limit of detection of 25 IU/L (or equivalent units) for human chorionic 
gonadotropin.  If a pregnancy test is positive, study drug treatment will be discontinued.   
Female patients of childbearing potential must use a highly effective form of birth control 
from the first dose of study drug through 45 days after the last dose of study drug, defined as 
follows:

Adverse Event Definitions and Reporting 
8.3.1 
Adverse Event Definitions 
Definitions are provided in this section for adverse events, events of special interest, serious 
adverse events, treatment-emergent adverse events, suspected unexpected serious adverse 
reactions (SUSARs), and unexpected adverse events.   
Adverse events:  An adverse event is any unfavorable and unintended sign (including 
an abnormal laboratory finding), symptom, or disease temporally associated with the use 
of a study drug, whether or not related to the study drug.   
Examples of adverse events include the following: 
• 
A worsening, excluding minor fluctuations, in the nature, severity, frequency, or 
duration of a pre-existing condition 
• 
Development of an intercurrent illness during the study 
• 
Development of symptoms that may or may not be related to the use of a concomitant 
medication or investigational product 
• 
Injury or accidents:  If a medical condition is known to have caused the injury or 
accident, the medical condition and the accident should be reported as 2 separate 
medical events (eg, for a fall secondary to dizziness, both “dizziness” and “fall” 
should be recorded separately) 
• 
An investigational abnormality (eg, laboratory parameter, vital sign, ECG) only if the 
abnormality is considered clinically significant by the investigator based on at least 
one of the following criteria: 
– Induces clinical signs or symptoms 
– Requires active intervention 
– Requires interruption or discontinuation of study drug 
An adverse event does not include the following: 
• 
Medical or surgical procedures (eg, surgery, endoscopy, tooth extraction, 
transfusion); the condition that leads to the procedure is an adverse event

Page 35 of 58 
• 
Pre-existing diseases or conditions present or detected before the start of study drug 
administration that do not worsen 
• 
Situations where an untoward medical event has not occurred (eg, planned 
hospitalization for an elective procedure) 
Serious adverse events:  Any adverse event that meets any of the criteria in Table 8 as 
determined by the investigator or sponsor.   
Table 8: Criteria for Serious Adverse Events 
Criterion 
Comment 
Results in death 
Death is an outcome, not an adverse event.  The 
primary adverse event resulting in the death 
should be identified.   
Is life threatening (immediate risk of death from 
the adverse event as it occurred) 
Does not include an event that hypothetically 
might have caused death if it were more severe.   
Results in or prolongs an existing inpatient 
hospitalization 
For hospitalizations for surgical or diagnostic 
procedures, the illness leading to the surgical or 
diagnostic procedure will be identified as the 
serious adverse event (not the procedure).   
Results in persistent or significant incapacity or 
substantial disruption of the ability to conduct 
normal life functions 
Permanent or substantial disruption of a person’s 
ability to conduct normal life functions.   
Results in a congenital anomaly/birth defect 
 
Important medical events which jeopardize the 
subject and may require medical or surgical 
intervention to prevent one of the outcomes listed 
above 
Examples include drug-induced bronchospasm 
requiring intensive treatment in an emergency 
room or at home, blood dyscrasias or convulsions 
that do not result in inpatient hospitalization, and 
the development of drug dependency or drug 
abuse.   
Source:  US Code of Federal Regulations:  21 CFR 312.32 [75 FR 59961] 
 
Treatment-emergent adverse events:  Adverse events observed following administration of 
the first dose of study drug.   
Unexpected adverse events:  Adverse events for which the nature or severity is not consistent 
with the reference safety information.   
Suspected unexpected serious adverse reactions (SUSARs):  Adverse events assessed as 
serious, related, and unexpected, which are subject to expedited reporting to regulatory 
authorities and study investigators.   
Adverse events of special interest:  Adverse events of special interest are any adverse events 
(serious or nonserious) identified for ongoing monitoring during the study and require rapid 
communication by the investigator to the sponsor as described in Section 8.3.6.

8.3.2 
Adverse Event Reporting 
Safety reporting to regulatory authorities, ethics committees, and investigators will be 
implemented according to global and country specific regulations.   
To elicit adverse event reports from patients, the study site personnel should question the 
patient in a general way without suggesting specific symptoms.   
All patients who experience an adverse event will be evaluated at appropriate time intervals 
until the event resolves or stabilizes.  At the conclusion of the study, the investigator and 
medical monitor will assess unresolved adverse events and determine if additional follow-up 
is warranted as described in Section 8.3.9.   
All adverse events, whether or not related to the study drug, must be fully and completely 
documented on the appropriate form and in the patient’s source documents.  In addition, any 
adverse event resulting in permanent treatment discontinuation must be recorded on the 
appropriate case report form as well as documented in the patient’s source documents.  
Adverse event terms should include a diagnosis, as available, in preference to listing the 
individual signs and symptoms.  If the diagnosis is not known, the investigator should record 
each sign and symptom as an individual adverse event.   
Overdose and pregnancy in the patient or partner will be reported as described in 
Sections 8.2.2 and 8.3.10, respectively.   
8.3.2.1 
Adverse Event Reporting Periods 
Collection and reporting of adverse event information will begin at the time the patient signs 
informed consent for serious adverse events and following the first dose of study drug for 
nonserious adverse events and will continue for all events through safety follow-up 
(approximately 30 days after the last dose of study drug), before initiation of a new 
antineoplastic therapy, or enrollment in the open-label extension study, whichever occurs 
first (Figure 2).  Additional reporting instructions for serious adverse events are provided in 
Section 8.3.6.

Figure 2: Adverse Event Reporting Periods 
 
All adverse events from the time of the first dose of study drug must be documented on the 
adverse event case report form and in the patient’s clinical record.  Any event occurring 
during screening and before the first dose must be documented on the medical history case 
report form and in the patient’s clinical record for any patient who subsequently meets 
eligibility criteria and proceeds to enrollment.   
8.3.3 
Assessment of Causal Relationship 
The investigator will assess the relationship of an adverse event to study drug treatment 
according to the criteria in Table 9 and document the relationship in the patient’s clinical 
record.   
Table 9: Criteria for Determining Causal Relationship to Study Drug 
Relationship 
Criteria  
Not Related 
A clinical event, including laboratory test abnormality, with a 
temporal relationship to drug administration that makes a causal 
relationship improbable, and/or in which other drugs, chemicals, 
or underlying disease provide plausible explanations.   
Possible 
A clinical event, including laboratory test abnormality, with a 
reasonable time sequence to administration of the drug, but that could 
also be explained by concurrent disease or other drugs or chemicals.  
Information on drug withdrawal may be lacking or unclear.   
Probable 
A clinical event, including laboratory test abnormality, with a 
reasonable time sequence to administration of the drug, unlikely to be 
attributed to concurrent disease or other drugs or chemicals, and that 
follows a clinically reasonable response on re-administration 
(rechallenge) or withdrawal (dechallenge).

8.3.4 
Assessment of Severity (Intensity) 
Severity describes the intensity of a specific adverse event (mild, moderate, or severe).  The 
particular event may be of relatively minor medical significance (such as severe headache).  
Severity is not the same as “serious,” which is based on patient/event outcome or action 
criteria.   
Investigators will grade the severity of adverse events according to the CTCAE, version 4.  
For terms not specified within the CTCAE, the criteria in Table 10 should be used to 
determine grade of severity.   
Adverse event severity should be recorded in the appropriate section of the adverse event 
case report form and in the patient’s source documents.

Adverse Events of Special Interest 
Adverse events of special interest include a diagnosis of MDS or acute myeloid leukemia 
(AML) (consistent with events observed with olaparib) and abnormal liver test results.  Liver 
test abnormalities that require reporting are the following: 
• 
AST or ALT ≥ 3 times ULN (> 5 × ULN if baseline ALT/AST is > 3 × ULN) and 
total bilirubin > 2 times ULN or INR > 1.5 
• 
AST or ALT ≥ 3 times ULN with signs and symptoms consistent with hepatitis 
and/or eosinophilia (≥ 500 eosinophils/µL) 
Adverse events of special interest occurring during the safety reporting period must be 
reported within 24 hours of awareness by the study site and those occurring after the safety 
reporting period must be reported within 1 week of awareness, using a serious adverse event 
report form (contact information provided in Section 8.3.6).

Tissue samples and any other supporting data used to enable the diagnosis of MDS or AML 
should be submitted for central review if requested.   
8.3.6 
Serious Adverse Event Reporting 
Study site personnel will collect serious adverse event information from the time the patient 
signs the informed consent form through screen failure or safety follow-up (approximately 
30 days after the last dose of study drug), before initiation of a new antineoplastic therapy, or 
enrollment in the open-label extension study, whichever occurs first.  Serious adverse events 
reported to the investigator after the safety reporting period should be reported to the sponsor 
if the investigator assesses the event as related to the study drug treatment.   
Using a serious adverse event report form (a sponsor-provided form in the study manual), all 
serious adverse events must be reported within 24 hours of the study site personnel’s 
knowledge of the event, regardless of the investigator assessment of the relationship of the 
event to study drug.   
The contact information for submission of serious adverse events, adverse events of special 
interest, and events of overdose or pregnancy is as follows:

8.3.7 
Clarification in Reporting of Deaths 
Information relating to any death at any time during the study (eg, date and primary cause) 
should be obtained and recorded on the appropriate case report form.   
Fatal events (regardless of relationship to study drug) should be reported as serious adverse 
events during the treatment-emergent safety reporting period defined in Section 8.3.2.   
Death per se is not an adverse event but is an outcome of an adverse event.  The specific 
cause of death should be reported whenever possible.   
8.3.8 
Clarification in Reporting of Disease Progression as an Adverse Event Term 
Disease progression is expected in this study population and “disease progression” should not 
be reported as an adverse event term.  When clinical disease progression is identified, the 
specific clinical event that identifies the disease progression should be reported as the 
adverse event term for standard adverse event and if applicable, serious adverse event 
reporting.   
8.3.9 
Follow-Up of Serious and Nonserious Adverse Events 
All adverse events reported during the study should be followed up at appropriate intervals 
until resolution, or until the event has stabilized, reached a new baseline, or a new 
antineoplastic therapy is initiated (all follow-up results are to be reported to the sponsor or 
designee).   
Adverse events that remain unresolved at the conclusion of the study may continue to be 
monitored if warranted based on clinical assessment by the investigator and medical monitor.   
Patients should be contacted by phone and written requests as appropriate for adverse event 
follow-up if they do not come to the clinic for safety follow-up as specified in Section 5.4.   
8.3.10 Pregnancy Reporting Procedure 
If a female study participant becomes pregnant between the first dose of study drug and 
45 days after permanent discontinuation of study drug treatment, or if a male study 
participant impregnates a partner between the first dose of study drug and 105 days after 
permanent discontinuation of study drug treatment, the study participant should report the 
pregnancy to the investigator.  The pregnancy is to be reported to the sponsor within 24 hours 
of awareness by the study site (contact information provided in Section 8.3.6), using the 
provided reporting forms.  The expected date of delivery or expected date of the end of the 
pregnancy, last menstruation, estimated conception date, pregnancy result, and neonatal data, 
etc, should be included in this information.   
The investigator will follow the medical status of the mother, as well as the fetus, and will 
report the outcome to the sponsor.

Clinical Laboratory Tests 
Routine clinical laboratory tests (hematology, serum chemistry) will be performed according 
to the schedules of activities (Appendix 1, Appendix 2).  Samples will be stored until the 
specified analyses are completed and then will be destroyed in accordance with standard 
laboratory practice and applicable local regulations.   
A list of the required routine clinical laboratory tests and other evaluations is provided in 
Table 11.  All samples for laboratory analysis must be collected, prepared, labeled, and 
shipped according to laboratory requirements.   
All clinical laboratory tests will be performed by the central laboratory specified in Form 
FDA 1572 Section 4 unless otherwise specified.  The central laboratory reference ranges will 
be used.  Eligibility at screening will be based on central laboratory assessments.   
A local clinical laboratory may be used to evaluate serum chemistry and hematology within 
3 days before a scheduled visit.  The results of these local laboratory assessments will be 
used for dosing decisions.   
For all patients, a local clinical laboratory may be used to assess samples at unscheduled 
visits or for urgent care to evaluate an adverse event.  Such laboratory data will not be 
entered into the study database and local laboratories will not be included on Form 
FDA 1572.  Central laboratory samples should be obtained whenever possible during 
unscheduled visits.

Physical Examinations, Vital Signs, and ECGs 
The investigator will perform physical examinations according to the schedules of activities 
(Appendix 1, Appendix 2).  Interval medical history will be reviewed as a part of physical 
examinations.   
Physical examinations will include an assessment of systems (eg, general appearance, head, 
eyes, ears, nose, mouth, skin, heart, lungs, lymph nodes, gastrointestinal, genitourinary, 
neurologic, and skeletal) per standard of care at the study site or as clinically indicated by 
symptoms.   
Vital sign measurements will include blood pressure (after supine for 5 minutes), heart rate, 
respiratory rate, and temperature at the visits noted in the schedule of activities.  Blood 
pressure (after supine for 5 minutes) will be measured 15 to 20 minutes before each PK time 
point.  Weight will be measured at the time of the examination.  Height will be measured 
only at screening.   
12-Lead ECGs will be obtained continuously at baseline (day -1) and days 1, 2, and 22, and 
a single ECG will be obtained at screening and safety follow-up.  ECGs will be collected for 
analysis at specified time points; patients must be supine for 10 minutes before these time 
points.  Additional ECGs may be obtained as necessary per standard of care.  For patients 
who enroll and initiate continued talazoparib treatment in the open-label extension study 
within 30 days, an ECG will be obtained at the time of enrollment in the open-label study.   
9 ASSESSMENT OF SAFETY, PHARMACOKINETIC, AND EFFICACY 
ENDPOINTS 
9.1 
Assessment of Safety 
The assessment of safety will include adverse events, physical examinations, vital signs, 
ECGs, and clinical laboratory tests.  The procedures for the investigator assessment of 
adverse events are presented in detail in Section 8.  The procedures for clinical laboratory 
safety tests are presented in Section 8.4, and for physical examinations, vital signs, and ECGs 
in Section 8.5.   
9.2 
Assessment of QTc 
ECG recordings from continuous 12-lead ECG recordings will be obtained using Holter 
monitors on days -1, 1, 2, and 22, and will be submitted for independent central review.  
After reviewing for data quality, triplicate 10-second ECGs will be extracted from a 5-minute 
extraction window at each planned time point and will be analyzed for measurement of RR, 
PR, QRS, and QT intervals and evaluation of ECG morphology.  A cardiologist will verify 
the interval durations and perform the morphology analyses.  Heart rate will be used to assess 
QTc endpoints.

10 STATISTICAL METHODS AND SAMPLE SIZE DETERMINATION 
10.1 Statistical and Analytical Plans 
The statistical methods and analyses for this study will be described in detail in the statistical 
analysis plan.   
10.2 Analysis Populations 
All safety analyses will be performed using the safety population, defined as all patients who 
receive any amount of talazoparib.   

Medivation, Inc. 
Talazoparib 
Protocol MDV3800-14/TRIO029 
19 AUG 2016 – v2.0 FINAL 
 
Page 44 of 58 
The ECG analysis population is defined as all enrolled patients who receive at least 1 dose of 
study drug, and have at least 1 available baseline and 1 on-treatment ECG.  Patients who do 
not complete day 22 or who miss > 5 consecutive doses of study drug will be excluded from 
the analysis of the effects of talazoparib on cardiac repolarization.   
The PK population is defined as all patients who receive at least 1 dose of talazoparib and 
provide at least 1 reportable concentration.  The PK analysis population is defined as all 
patients who have sufficient concentration data to derive at least 1 PK parameter.  Additional 
patients may be excluded from the PK population at the discretion of the pharmacokineticist.   
The PK-PD analysis population is defined as all patients in the ECG analysis population who 
have at least 1 time-matched pair of plasma concentration and ECG measurements obtained 
at the same nominal time point.  Additional details on the PK-PD analysis population are 
provided in the statistical analysis plan.   
10.3 Safety Analyses 
All safety analyses will be performed using the safety population, as defined in Section 10.2.  
Drug exposure will be summarized using descriptive statistics.   
The safety of talazoparib will be evaluated by the analysis of incidence of serious and 
nonserious adverse events, severity of adverse events, incidence of dose modifications and of 
permanent treatment discontinuation due to adverse events, and incidence of new clinically 
significant changes in vital signs, ECGs, and clinical laboratory values.  Treatment-emergent 
safety data will be collected from the first dose of study drug treatment through 30 days after 
the last dose (ie, permanent discontinuation), before initiation of a new antineoplastic 
therapy, or enrollment in the open-label extension study, whichever occurs first.   
Adverse events will be coded to preferred term and system organ class using the Medical 
Dictionary for Regulatory Activities (MedDRA) and classified by severity using the CTCAE 
version 4.  The number and percentage of patients with adverse events will be presented by 
MedDRA system organ class and preferred term, relationship to study treatment, severity, 
seriousness, and outcome (eg, leading to permanent treatment discontinuation).   
Laboratory values will be classified for severity using the CTCAE version 4.  Laboratory 
shift tables of baseline results versus postbaseline results to each subsequent visit will be 
produced as appropriate.   
10.4 ECG Analyses 
All ECG analyses will be conducted using the ECG analysis population.  The primary 
endpoints of the study are to evaluate the effects of talazoparib on the QTcF, and to evaluate 
the relationship between the plasma concentration of talazoparib and the change from 
baseline in QTc, corrected for heart rate based on the QTcF correction formula (∆QTcF).  
The time-matched change from baseline in QTc, corrected for heart rate based on Bazett’s 
correction formula (∆QTcB), will also be evaluated.  Changes from time-matched baseline 
measurements will be calculated and data will be summarized in tabular and graphic formats

for each study visit.  Assessments include absolute QTc prolongation with QTc > 450 msec, 
> 480 msec, and > 500 msec and change from baseline in QTc with QTc increase > 30 msec 
and > 60 msec.  The means of each measurement of RR, PR, QRS, and QT intervals will be 
utilized for statistical analyses.   
ECG morphology and changes from baseline for each planned postbaseline time point will be 
summarized for all patients.  The proportion of patients with any postbaseline change in ECG 
morphology and the proportion of patients with each type of abnormality will also be 
summarized.   
10.5 
PK Analyses 
Summary data of plasma talazoparib concentrations will be presented in tabular and graphic 
formats for each time point.  PK parameters such as Tmax, Cmax, and AUC on days 1 and 22 
will be calculated.   
In addition, the PK data from this study will be combined with PK data from other studies to 
define a population PK model, which will be reported separately.   
10.6 
PK-PD Analyses 
The correlation between changes in ECG interval measurements from time-matched baseline 
and the plasma talazoparib concentration will be investigated using a linear mixed-effects 
model.   
This analysis will be conducted using the PK-PD analysis population.   
10.7 
Efficacy Analyses 
No efficacy analysis is planned in this study.   
10.8 
Determination of Sample Size 
A sample size of at least 30 evaluable patients will provide 80% power to reject the null 
hypothesis if the mean change from baseline in QTcF is ≥ 10 msec with a 95% one-sided 
alpha, assuming a standard deviation of 20 msec.  Patients will be enrolled until 30 patients 
complete day 22, miss ≤ 5 consecutive doses of study drug, have technically adequate ECG 
recordings, and have at least 80% of specified PK samples collected representing all 3 days 
of observation (days 1, 2, and 22).

13.2 Data Quality Assurance 
13.2.1 Data Management 
Clinical data management will be performed by the sponsor or designee according to 
procedures described in a comprehensive data management plan.  The data management plan 
will include procedures for processing the data from this study, and will describe the 
responsibilities of the sponsor and designee when clinical data management is provided by an 
external vendor.  In particular, the data management plan will include a list of the standard 
operating procedures that apply to this study.   
Adverse events and medications will be coded using MedDRA and the World Health 
Organization Drug Dictionary (WHO-DD), respectively.  The dictionary versions will be 
named in the data management plan.   
13.2.2 Case Report Forms 
The study will use an electronic data capture system.  All electronic case report forms will be 
designed and provided electronically to the site by the sponsor or designee and electronic 
data capture system vendor.  All case report form books are to be filled out completely, 
reviewed, and signed by the investigator or subinvestigators listed on the Form FDA 1572 or 
other appropriate local health authority documents.   
13.2.3 Study Monitoring 
The sponsor or designee will monitor this study in accordance with current GCP guidelines.  
By signing this protocol, the investigator grants permission to the sponsor or designee and 
appropriate regulatory authorities to conduct onsite monitoring of all appropriate study 
documentation.  To ensure the accuracy of data collected on the case report forms, it is 
mandatory that sponsor representatives (eg, study monitor) have direct access to original 
source documents (eg, paper or electronic patient records, patient charts, and laboratory 
reports) needed to verify the entries on case report forms.  During the review of these 
documents, the anonymity of the patient will be respected with strict adherence to 
professional standards of confidentiality.   
A study monitor will contact and visit the site regularly and will be allowed, on request at 
a mutually acceptable time, to inspect the various original medical records (paper or 
electronic) related to the study.  The study monitor will be responsible for inspecting the case 
report forms at regular intervals throughout the study, to verify the adherence to the protocol 
and the completeness and correctness of all case report form entries.  The investigator agrees 
to cooperate with the study monitor to ensure that any problems detected in the course of 
these monitoring visits are resolved.

13.2.4 Study Audits 
During the course of the study and after study completion, it is likely that one or more quality 
assurance audits will be undertaken by authorized sponsor representatives.  The purpose of 
the audit is to ensure that the study is (or was) conducted and monitored in compliance with 
the protocol as well as recognized GCP guidelines and regulations.  These audits will also 
increase the likelihood that the study data and all other study documentation can withstand 
a regulatory authority inspection.  If such audits are to occur, they will be arranged for 
a reasonable and agreed upon time.  By signing this protocol, the investigator grants 
permission to the sponsor or designee to conduct onsite audits of all appropriate facilities and 
study documentation.   
13.3 Investigational Product Accountability 
The investigator must maintain accurate records of all study drug supplies received.  All 
records must be made available to the sponsor, authorized representatives, and appropriate 
regulatory agencies, upon request.   
Current ICH GCP guidelines require the investigator to ensure that study drug deliveries 
from the sponsor are received by a responsible person (eg, pharmacist), and the following: 
• 
That such deliveries are recorded, for example, on the sponsor’s drug accountability 
log or other sponsor-approved pharmacy log 
• 
That study drug is handled and stored safely and properly in accordance with the label 
and the study protocol 
• 
That study drug is only administered or dispensed to study patients in accordance 
with the protocol 
• 
That any used or unused drug is returned by the patient at each required visit 
• 
That any unused study drug is returned to the sponsor-designated facility or standard 
procedures for the alternative disposition of unused study drug are followed and only 
after approval by the sponsor representative 
Drug inventory and accountability records for the study drugs will be kept by the 
investigator/pharmacist.  Study drug accountability throughout the study must be 
documented.  The following guidelines are therefore pertinent: 
• 
The investigator agrees not to supply study drug to any persons except the patients in 
this study.   
• 
The investigator/pharmacist will keep the study drugs in a pharmacy or other locked 
and secure storage facility under controlled storage conditions as required by the 
study drug label, accessible only to those authorized by the investigator to dispense 
these study drugs.   
• 
The investigator/pharmacist will maintain a study drug inventory.  The inventory will 
include details of material received and a clear record of when they were dispensed 
and to which patient.

Talazoparib 
Protocol MDV3800-14/TRIO029 
19 AUG 2016 – v2.0 FINAL 
 
Page 50 of 58 
• 
The investigator/pharmacist agrees to conduct a final drug supply inventory and to 
record the results of this inventory on the drug accountability record at the conclusion 
or termination of this study.  It must be possible to reconcile delivery records with 
those of used and returned study drug.  Any discrepancies must be accounted for.  
Appropriate forms of deliveries and returns must be signed by the person responsible.   
• 
Used or unused study drug may be destroyed at the study site according to standard 
institutional procedures if the sponsor agrees with the procedure, and after drug 
accountability has been conducted by the sponsor or representative, unless otherwise 
approved.  A copy of the standard institutional procedure for destroying 
investigational drugs will be provided to the sponsor or designee upon request for 
review and approval before the first onsite destruction.  Unused study drug not 
destroyed at the site must be returned to the sponsor-designated facility at the end of 
the study or upon expiration.   
13.4 Compensation, Insurance, and Indemnity 
In the event of a side effect or injury, appropriate medical care as determined by the 
investigator or designated alternate will be provided.   
If bodily injury is sustained, resulting directly from the use of the study drug or by required 
study procedures, the sponsor will reimburse for reasonable physician fees and medical 
expenses necessary for treatment of only the bodily injury that is not covered by the patient’s 
medical or hospital insurance, provided that the injury is not due to a negligent or wrongful 
act or omission by the study doctor and study staff.  No other compensation of any type will 
be provided by the sponsor.  Financial compensation for lost wages, disability, or discomfort 
due to the study participation or procedures is not available.   
13.5 Retention of Records 
The investigator must make original study data (paper or electronic) accessible to the study 
monitor, other authorized sponsor representatives, and regulatory agency inspectors 
(eg, US FDA) upon request.  A file for each patient must be maintained that includes the 
signed informed consent form and copies of all source documentation related to that patient.  
The investigator must ensure the reliability and availability of source documents from which 
the information on the case report form was derived.   
Patient identity information recorded will be maintained for at least 15 years on the patient 
confidentiality log or longer if required by local regulations.   
Investigators must maintain all study documentation for at least 2 years following the 
approval of the drug, or until 2 years after the investigational drug program is discontinued, 
or longer if required by local regulations.  Study documentation includes all essential 
documents as defined in ICH E6 Guidelines for Good Clinical Practice.  The sponsor or 
designee will notify the investigator when any records may be discarded, but investigators 
must comply with local regulations.

13.6 Study Termination 
The sponsor will terminate this study following completion of the study objectives, or earlier 
if deemed necessary.   
The sponsor reserves the right to terminate the study anytime.  When the sponsor is aware of 
information on matters concerning the quality, efficacy, and safety of the study drug, as well 
as other important information that may affect proper conduct of the clinical study, the 
sponsor may terminate the study and send a written notice of the termination along with the 
reasons to the investigator.   
If an investigator or the investigator’s EC intends to terminate participation in the study, the 
investigator must immediately inform the sponsor and provide the reason for it.   
14 USE OF STUDY INFORMATION AND PUBLICATION 
The results of this study will be published or presented at scientific meetings in a timely, 
objective, and clinically meaningful manner that is consistent with good science, industry and 
regulator guidance, and the need to protect the intellectual property of Medivation (sponsor), 
regardless of the outcome of the trial.  The data generated in this clinical trial are the 
exclusive property of the sponsor and are confidential.  Written approval from the sponsor is 
required before disclosing any information related to this clinical trial, and no publications 
initiated by investigators may be published until all protocol-defined primary and secondary 
endpoints are published in a manuscript.  Every attempt will be made to minimize the 
interval between the completion of data analysis and publication of the study results.  
Recommendations for the timing of presentation of trial endpoint data and the publication 
venues (congresses/journals) will be given by the sponsor’s Publications Steering 
Committee.   
Each investigator agrees to submit all manuscripts or congress abstracts and 
posters/presentations to the sponsor prior to submission.  This allows the sponsor to protect 
proprietary information, provide comments based on information from other studies that may 
not yet be available to the investigator, and ensure scientific and clinical accuracy.  The 
details of the processes of producing and reviewing reports, manuscripts, and presentations 
based on the data from this trial will be presented in the investigator’s clinical study 
agreement.   
In accord with standard editorial and ethical practice, the sponsor will generally support 
publication of multicenter trials only in their entirety and not as individual center data.  
In this case, a coordinating investigator and lead author will be designated by mutual 
agreement.   
Any formal publication of the study in which input of sponsor personnel exceeded that of 
conventional monitoring will be considered as a joint publication by the investigator and the 
appropriate sponsor personnel.  Authorship will be determined by mutual agreement and all 
authors must meet the criteria for authorship established by the International Committee of 
Medical Journal Editors (ICMJE) Uniform Requirements for Manuscripts or stricter local

criteria (ICMJE, 2015).  The sponsor does not compensate for authorship of a publication and 
all authors will be required to disclose, as part of the publication submission, any potential 
conflicts of interest, including pertinent financial or personal relationships with the sponsor 
or related entities, including sponsors of competing products that might be perceived to be 
a source of bias.  Authorship is decided on an individual basis and the sponsor’s Publications 
Steering Committee and sponsor representatives will mutually determine authors and their 
sequence on individual publications based on the relative contribution of each author to the 
study and/or publication.   
Investigators in this study agree to have their name listed as an investigator in any 
publication reporting results from this study, whether or not they are an author on the 
publication.   
Professional medical writing support is permissible, and any writing support will be 
acknowledged in each applicable publication, explaining the role the professional writer had 
in the drafting of the publication.  Medical writing and publications support funded by the 
sponsor on behalf of investigator authors will be considered as a transfer of value under the 
reporting requirements of Section 6002 of the Patient Protection Affordable Care Act 
(PPACA, 2010).  Transfer of value will be allocated to authors following sponsor guidelines.

Anytime necessary to assess or follow up adverse events, at the patient’s request, or per investigator decision.   
[2] 
Safety follow-up occurs approximately 30 days after the last dose of study drug or before initiation of a new antineoplastic therapy, whichever occurs 
first.  Phone patients for adverse event follow-up if they do not come to the clinic.  For patients who enroll and initiate continued talazoparib treatment 
in a separate open-label extension study within 30 days after the last dose of talazoparib, safety follow-up will be omitted; an ECG will be obtained at 
the time of enrollment in the open-label extension study.   
[3] 
On day -1 (time 0, corresponding to the dosing time on day 1), apply Holter monitor and record ECGs for 6 hours.  On day 1 (within 72 hours of 
time 0 on day -1, corresponding to the clock time of the first baseline ECG measurement), start recording ECGs at least 45 minutes before time 0, 
administer the first dose of study drug at time 0, and continue recording ECGs for 6 hours postdose.  On day 2 (24 hours after the first dose of study 
drug), start recording ECGs at least 30 minutes before day 2 dose.  On day 22, start recording ECGs at least 45 minutes before time 0, administer study 
drug at time 0, and continue recording ECGs for 6 hours postdose.  (Appendix 3)   
[4] 
Obtain a single 12-lead ECG (after supine for 10 minutes); obtain at the time of enrollment in the open-label extension study for patients who enroll in 
that study within 30 days.

[5] 
Measure blood pressure (after supine for 5 minutes), heart rate, respiratory rate, and temperature at each visit.  On days -1, 1, 2, and 22, measure blood 
pressure (after supine for 5 minutes) 15 to 20 minutes before each PK time point (Appendix 3).   
[6] 
Assess systems (eg, general appearance, head, eyes, ears, nose, mouth, skin, heart, lung, lymph nodes, gastrointestinal, genitourinary, neurologic, and 
skeletal) per standard of care at the study site or as clinically indicated by symptoms.  Measure weight.  May be skipped on day -1 if performed within 
prior 7 days.   
[7] 
Collect serious adverse event information from the time of signed informed consent through approximately 30 days after the last dose of study drug, 
before a new antineoplastic therapy, or enrollment in the open-label extension study, whichever occurs first.  Collect nonserious adverse event 
information from day 1 through approximately 30 days after the last dose of study drug, before initiation of a new antineoplastic therapy, or 
enrollment in the open-label extension study, whichever occurs first.   
[8] 
Administer talazoparib at the study site on days 1, 2, and 22; administer talazoparib on days 2 and 22 at the same clock time as time 0 (±1 hour) on 
day 1.  Instruct patient to self-administer talazoparib at approximately the same time each morning on day 3 through day 21.   
Patients will fast for at least 6 hours before and 2 hours after the dose on days 1 and 22.  Patients may resume eating after the 2-hour postdose PK 
sample is collected.  On other days, talazoparib may be taken with food or without food.   
[9] 
Refer to the central laboratory instruction manual for sample processing and for estimated turnaround time for laboratory results.   
[10] 
Collect blood samples for PK on day 1 immediately before the first dose of study drug and at 1, 2, 4, and 6 hours postdose; on day 2 at 24 hours after 
the first dose of study drug (and before day 2 dose); and on day 22 predose and at 1, 2, 4, and 6 hours postdose.  After obtaining vital signs, patient 
should remain supine for 10-15 minutes before collecting blood sample for PK (Appendix 3).   
[11] 
For women of childbearing potential only.  Perform urine or serum pregnancy test either locally or using a centrally provided kit with a minimum 
sensitivity of 25 IU/L or equivalent units human chorionic gonadotropin.  Discontinue study drug treatment if a pregnancy test is positive.

[1] At 15-20 minutes before each PK time point, measure blood pressure (after supine for 5 minutes).   
[2] After obtaining blood pressure, patient should remain supine for 10 to 15 minutes before collecting 
blood sample for PK.   
[3] ECG recordings on days -1, 1, 2, and 22 are continuous ECG recordings by Holter monitor.   
[4] Time 0 corresponds to the dosing time on day 1.  Administer the dose of talazoparib on days 2 
and 22 at the same clock time as time 0 (±1 hour) on day 1.
