Objectives 
Primary: 
• 
To determine the time course of excretion of 14C-radioactivity in urine and feces following a single 
1 mg oral dose of talazoparib containing 100 µCi 14C-talazoparib. 
• 
To determine the recovery of 14C radioactivity as a percentage of the administered dose. 
• 
To determine the plasma pharmacokinetics (PK) of talazoparib and/or potential metabolites. 
• 
To determine the PK of total radioactivity of 14C-talazoparib, (AUC0-inf, AUC0-last, Cmax, Tmax, T1/2, CL/F, 
and Vd/F) in plasma and whole blood. 
 
Secondary: 
 
• 
To assess the safety and tolerability of a single dose of 1 mg talazoparib containing 100 µCi 14C-
talazoparib. 
• 
To determine the percentage of 14C radioactivity of talazoparib associated with erythrocytes and whole 
blood over time. 
• 
To determine the amount of talazoparib in urine and feces. 
• 
To estimate the amount and probable structure of any significant metabolites of talazoparib in plasma, 
urine and feces. 
 
Design and Treatments 
This is a Phase 1, single-center, open-label study evaluating the mass balance of talazoparib after a single 
dose of 1 mg talazoparib 100 µCi (3.7 MBq) 14C-talazoparib; subjects may elect to continue treatment on 
an extension protocol. 
The study is planned to enroll at total of up to approximately 6 patients in order to obtain the data in at 
least 4 evaluable patients at a single Phase 1 unit. Patients will receive a single dose of 1 mg talazoparib 
oral solution containing approximately 100 µCi 14C-talazoparib on Day 1 after an overnight fast of at least 8 
hours. No food will be allowed for at least 2 hours post-dose. 
Within this food-restricted period the consumption of water is allowed. 
The patients will remain at the clinic for approximately 21 days. If scintillation count data are available, 
patients, on an individual basis, may be discharged prior to Day 22, if any of the following conditions are 
met: 
• 
≥ 90% of the administered radioactivity is recovered in the urine and feces (accounting for radioactivity 
in vomitus, if applicable) 
• 
The daily total excreted radioactivity is 1% or less of the administered dose on 2 consecutive days. 
Shipments for daily Quick Count will start on Day 10 
If a patient meets either of these conditions prior to the morning of Day 22, collection of blood, urine, and 
feces may be stopped following completion of all scheduled 24-hour collections for that day. At the 
conclusion of the blood, urine, and feces collection, the patients will be discharged following completion of 
any safety procedures scheduled at termination. 
If an individual patient does not demonstrate a cumulative amount of radioactivity recovered in urine and 
feces ≥ 90% or has not met the daily total excretion criteria of 1% or less of the administered dose on 2 
consecutive days, following consultation with the Sponsor, the Investigator may ask patient to return to the 
clinic on Day 28 for a 24 h collection of urine and feces. If, by Day 29, the patient has still not met release 
criteria, a discussion between the Sponsor and the Investigator will be conducted for possibility to collect 
additional 24 h collection of urine and feces on Day 35. 
Patients participating in this study with no clinically significant toxicities may be eligible to continue 
treatment on a separate extension protocol after discussion with the Principal Investigator and obtaining 
Sponsor permission. Decision to allow the patient to continue dosing with unlabeled (non-radioactive)

talazoparib in an open label study will be based on potential overall benefit-risk to patients, and patient 
eligibility for enrollment in the open-label extension study. 
Safety data for all patients who had received any amount of talazoparib will be analyzed in the safety 
analyses. 
 
Study Assessments 
Safety and tolerability of talazoparib will be monitored through evaluation of adverse events, clinical 
laboratory tests, vital signs, electrocardiogram (ECG) recordings and physical examinations. 
Serial PK blood, urine, and feces samples for talazoparib (plasma) and total radioactivity (whole blood, 
plasma, urine, feces, and vomitus, if applicable) analysis will be collected at predetermined times after the 
single oral dose administration, up to 504 hours (21 days), during which time the patients will be confined 
to the clinical research facility. Blood samples for plasma total radioactivity and for PK analysis of 
talazoparib and/or potential metabolite profiles and concentrations will be collected at pre-dose and 0.5, 1, 
2, 4, 8, 12, 24, 48, 72, 96, 120, 168, 216, 264, 336, 384, 432 and 504 hours post-dose. Whole blood 
samples for total radioactivity will be collected at pre-dose and 0.5, 1, 2, 4, 8, 12, 24, 48, 72, 96, 120, 168, 
216, 264, 336, 384, 432 and 504 hours post-dose. Urine and feces samples will be collected for the 
analysis of total radioactivity and for analysis for talazoparib and/or metabolites. Urine samples will be 
collected at pre-dose and during 0–8 hour and 8–24 hour post-dose intervals on Day 1 and then continue 
in 24-hour intervals through Day 22. Feces samples will be collected pre-dose and post-dose at 24-hour 
intervals through the morning of Day 22. Additional blood samples for PK analysis may be taken at the 
prolongation observation period and additional (unscheduled) and follow-up visit(s). During these visits, all 
urine and feces for total radioactivity analysis will be collected. 
 
Key Eligibility Criteria 
This study will enroll patients with certain advanced solid tumors (i.e. platinum-resistant ovarian carcinoma, 
cervical adenocarcinoma, small cell lung carcinoma and triple-negative breast cancer) who are at least 18 
years of age and provide informed consent. Patients must abstain from the use of any prescription or 
nonprescription drugs or supplements with potential P-glycoprotein (P-gp) interaction within 7 days or 5 
half-lives (whichever is longer) before Day 1. Patients must not have eGFR (estimated glomerular filtration 
rate) ≤ 50 mL/min/1.73 m2 by MDRD (Modification of Diet in Renal Disease) equation at screening and 
baseline, human immunodeficiency virus (HIV), hepatitis B, or hepatitis C. Patients who had major surgery 
within 8 weeks, or received any investigational drug within 4 weeks before screening are excluded. Female 
and male patients of childbearing potential must agree to use a highly effective birth control method 
starting on 21 days before the administration of talazoparib through 45 and 105 days after last dose of 
study drug, respectively. 
 
Duration of Study 
Approximately 3-4 weeks for each patient. 
 
Sample Size Considerations 
The study is planned to enroll a total of up to 6 patients in order to obtain the data in at least 4 evaluable 
subjects. This sample size is consistent with typical study designs for phase 1 mass balance studies for 
PK evaluation. Patients who discontinue before 85% of total drug is recovered from urine and feces may 
be replaced upon agreement of the Investigator and the Sponsor. 
 
Test Product, Dose, and Mode of Administration

Patients will receive a single dose of 1 mg talazoparib oral solution containing approximately 100 µCi of 
14C-talazoparib as a single dose. 
Reference Therapy, Dose, and Mode of Administration 
Not applicable. All patients will receive talazoparib. 
 
Statistical Methods 
Pharmacokinetic Analyses 
Radioactivity in urine and feces will be measured and reported as the percentage of the administered 
radioactivity excreted at each time interval and the total percent of dose excreted in urine and feces. 
talazoparib and/or potential metabolites will be also quantified in urine and feces and reported. Renal 
clearance will be calculated. 
Non-compartmental pharmacokinetic parameters will be calculated from the plasma and whole blood 
radioactivity concentration versus time data. Unchanged talazoparib and/or potential metabolites in plasma 
will be measured and reported. Non-compartmental pharmacokinetic parameters (AUC0-inf, AUC0-last, Cmax, 
Tmax, T1/2, CL/F, and Vd/F) will be calculated from the plasma and whole blood concentration time data. 
 
Efficacy Analyses 
No efficacy analyses are planned in this study, although baseline tumor assessments will be obtained in 
the event that patients choose to continue talazoparib treatment on a separate extension protocol. 
 
Safety Analyses 
All safety analyses will be performed using the safety population, defined as all patients who received any 
amount of talazoparib. Safety will be evaluated using summaries of adverse events (AEs), physical 
examinations (and weight), vital signs, ECG recordings, and laboratory evaluations. 
AEs 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 AEs will be 
presented by MedDRA system organ class and preferred term, relationship to study treatment, severity, 
seriousness, and outcome (e.g., leading to permanent treatment discontinuation). 
Treatment-emergent safety data will be collected from Day 1 (the first and only dose of study drug) through 
14 days after the last day of mass balance phase and at least 30 days after Day 1 or before initiation of 
new cytotoxic chemotherapy, new investigational treatment, or the first day of extension protocol, 
whichever occurs first. 
Laboratory values will be classified by severity using the CTCAE Version 4. Change from baseline in 
laboratory values will be tabulated and summarized graphically.

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 via two mechanisms, catalytic inhibition of PARP1 and PARP2, and 
PARP trapping, a process in which PARP protein bound to an inhibitor does not readily 
dissociate from DNA, preventing DNA repair, replication, and transcription. 
Talazoparib is cytotoxic to human cancer cell lines harboring gene mutations that 
compromise DNA repair, an effect referred to as synthetic lethality. In breast cancer 
MX-1 cells that are breast cancer susceptibility gene (BRCA)1-deficient, talazoparib 
inhibits cell growth in vitro and inhibits tumor growth and/or induces tumor regression in 
mouse xenografts. Antitumor activity was also demonstrated in small cell lung cancer 
(SCLC) cell lines and xenograft models; single-agent talazoparib reduced tumor growth 
to a similar extent as cisplatin in two independent SCLC xenograft models. 
Nonclinical studies demonstrated increased cytotoxic effects when talazoparib was 
combined with certain DNA damaging chemotherapies such as alkylating agents or 
topoisomerase I inhibitors. Non-cytotoxic concentrations of temozolomide greatly 
enhanced the cytotoxic effects of talazoparib in tissue culture studies using prostate, 
leukemia, and Ewing sarcoma cells. Enhancement of talazoparib cytotoxic effects 
results from temozolomide induced cytotoxic DNA adducts that can be removed by O6 
methylguanine methyltransferase (MGMT) and also potentially lethal DNA adducts that 
are dependent on the base excision repair (BER) response. Temozolomide induces 
numerous sites for PARP-DNA complexes to form and become trapped by talazoparib. 
Similarly in an SCLC xenograft model in mice, combination treatment with talazoparib 
plus temozolomide resulted in a marked enhancement of antitumor effects compared 
with that observed with either agent alone. Tissue culture studies of talazoparib in 
combination with the active metabolite of irinotecan, SN38, also demonstrated 
enhanced pharmacologic effects of combination versus single agent treatment. 
For further details on topics in this section refer to the current Investigator's Brochure 
(IB) 1. 
1.1.1 
Nonclinical Studies 
The main nonclinical toxicology findings with talazoparib were early hematologic 
changes and subsequent bone marrow and lymphoid organ depletion, as well as focal 
atrophy and degeneration of testes after repeat-dose talazoparib. These findings are 
consistent with the exaggerated pharmacology of talazoparib and its tissue exposure 
pattern. The hematologic findings were generally reversible and the early hematologic 
changes represent sensitive and early markers of target organ toxicity. 
1.1.2 
Clinical Studies 
As of 30 Nov 2015, approximately 319 patients with hematologic malignancies and 
solid tumors and 18 healthy volunteers have received talazoparib at doses up to 
2 mg/day. The majority of available efficacy and safety data was obtained from studies

VERSION Final 3.0 – 07-Oct-2016

in solid tumors. A Phase 1 study in patients with advanced or recurrent solid tumors 
defined the maximum tolerated dose (MTD) of talazoparib as 1 mg/day. 
1.1.2.1 
Pharmacokinetics 
The pharmacokinetics (PK) of talazoparib as a single agent was evaluated in 142 adult 
patients with cancer. Of these, 109 patients had solid tumors (PRP-001) and 33 had 
hematologic malignancies (PRP-002). Doses of 0.025 to 2 mg/day were administered 
orally as a single dose or as multiple doses. This 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 for all 142 patients. 
Oral absorption of talazoparib was rapid and independent of dose after administration 
of single or once-daily doses. Peak talazoparib concentrations were generally achieved 
approximately 1 to 8 hours post-dose. Elimination appeared to follow biphasic kinetics, 
with a mean half-life (T1/2) that ranged from 52.9 to 229 hours. The mean T1/2 of 
talazoparib showed some evidence of decreasing with increasing dose. At 1 mg/day, 
the mean T1/2 was approximately 2 days. With daily administration, it took 
approximately 2 to 3 weeks to reach steady state. 
The apparent volume of distribution (V/F) of talazoparib appeared to decrease with 
increasing dose. At 1 mg/day, the mean V/F was 415 L, or approximately 10-fold 
greater than total body water (42 L), which is indicative of extensive extravascular 
distribution2. In vitro protein binding data showed that talazoparib is 78.7% bound to 
human plasma proteins. 
No clinical studies have investigated penetration of talazoparib into the brain or 
cerebrospinal fluid. Talazoparib showed negligible penetration across the blood-brain 
barrier in rats. 
Apparent total body clearance (CL/F) of talazoparib appeared to be dose linear. The 
mean CL/F across doses was approximately 5 L/hr. Clinical data showed that renal 
excretion is 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 to 4.96 L/h, independent of dose, suggesting linear urinary 
elimination kinetics. The extent of metabolism was also minimal in nonclinical studies. 
Following oral administration of 14C-talazoparib to rats and dogs, talazoparib was 
cleared primarily via excretion of unchanged parent drug and metabolized to a minor 
extent via oxidation and dehydrogenation. In vitro metabolism studies in 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 human hepatocytes or cryopreserved 
human hepatocytes. 
Following administration at 1 mg/day, talazoparib accumulated approximately 2.4-fold 
relative to a single dose. At steady state, the mean maximum observed plasma 
concentration (Cmax) was 21.0 ng/mL, the mean plasma trough concentration (Cmin) was

MDV3800-03/MVE010PC-160106 
 
VERSION Final 3.0 – 07-Oct-2016 
 
 
Page 22 of 53 
3.72 ng/mL, the mean area under the concentration-time curve (AUC) was 
202 ng•h/mL, and the mean peak-to-trough ratio was approximately 6. 
Food Effect 
A food-effect study (673-103) involving administration of a single 0.5 mg dose of 
talazoparib to 18 healthy male subjects both under fasting conditions and with a 
high-fat, high-calorie meal showed that food had no effect on the extent of absorption 
(AUC). Food decreased the rate of absorption (Cmax was 46% lower and 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, it is thought that AUC or Cmin drives efficacy, 
not Cmax; therefore, talazoparib can be taken with or without food. Talazoparib is being 
administered without regard to meals in ongoing safety and efficacy trials. 
Pharmacokinetics in Special Populations 
A preliminary population PK analysis was performed with data from patients in studies 
PRP-001 and PRP-002 to assess the effects of renal function on PK parameters of 
talazoparib. Talazoparib apparent systemic clearance (CL/F) in patients with mild renal 
impairment (creatinine clearance [CLCR], 60-89 mL/min) was similar compared with 
patients with normal renal function (CLCR ≥ 90 mL/min). In patients with moderate renal 
impairment (CLCR, 30-59 mL/min), the talazoparib CL/F was decreased by 44%, 
resulting in higher talazoparib exposure. Therefore, patients with moderate or severe 
renal impairment (CLCR < 60 mL/min) may be at risk of elevated exposure ≥50%) to 
talazoparib. 
The effects of hepatic impairment on talazoparib PK have not been studied. 
Drug-Drug Interaction 
Talazoparib is unlikely to demonstrate clinically significant cytochrome P450 (CYP450) 
inhibition- or induction-based drug-drug interactions or drug transporter inhibition-based 
drug-drug interactions when co-administered with corresponding substrates. However, 
talazoparib is a substrate for P-glycoprotein (P-gp) and the breast cancer resistance 
protein (BCRP), and plasma talazoparib concentrations may increase or decrease 
when co-administered with P-gp or BCRP inhibitors or inducers, respectively. 
Efficacy 
Preliminary data demonstrated objective responses and/or likely clinical benefit in 
patients with breast, ovarian/peritoneal, and pancreatic cancer with deleterious 
germline mutations; SCLC; and Ewing’s sarcoma. A Phase 2 study and a Phase 3 
study in patients with locally advanced or metastatic breast cancer with deleterious 
germline BRCA mutations are both ongoing. Efficacy data are not yet available. 
The efficacy signals of talazoparib observed in the treatment of cancers with and 
without BRCA mutations warrant the continued development of talazoparib as a single 
agent at doses of 1 mg/day and support the hypothesis for enhanced cytotoxicity of 
talazoparib by the addition of DNA damaging agents.

Safety 
The most common adverse events (AEs) associated with talazoparib collected in 214 
patients participating three clinical studies (PRP-001, PRP-002, and 673-201) were 
myelosuppression (anemia, neutropenia, thrombocytopenia), gastrointestinal toxicity 
(nausea, vomiting, diarrhea), and fatigue. The most common National Cancer Institute 
(NCI) Common Terminology Criteria for Adverse Events (CTCAE) grade ≥ 3 AEs and 
serious adverse events (SAE) were associated with myelosuppression. 
A total of 25 of 214 patients had SAEs 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, none was assessed as related to the study drug. 
Adverse events leading to dose interruptions occurred in approximately 45%, 49%, and 
57% of patients in company-sponsored studies PRP-002 and PRP-001, and 
investigator-sponsored study NCT02049593 (combination treatment), respectively. 
Adverse events leading to dose reductions occurred in approximately 6% of patients in 
PRP-002, more than 17% of patients in PRP-001, and more than 20% of patients in 
NCT02049593. Most dose modifications were due to myelosuppression. 
Potential risks associated with talazoparib include hepatotoxicity, neutropenic sepsis, 
and febrile neutropenia. 
1.2 
Study Rationale 
The aim of this trial is to evaluate the metabolism and mass balance (i.e., recovery) of 
talazoparib, to identify the major route(s) of talazoparib elimination, to identify 
talazoparib metabolites in plasma, urine and feces and to determine the plasma 
concentration-time profiles of talazoparib and its metabolites in humans. 
The need for mass balance trials in anticancer drug development has recently been 
emphasized by both the Food and Drug Administration (FDA) and the European 
Medicines Agency (EMA) in the ICH S9 and EU guidelines on the evaluation of 
anticancer medicinal products 2,4. 
1.2.1 
Radioactively labeled dose (Mass Balance) of Talazoparib 
Administration of an oral solution containing 100 µCi 14C-talazoparib is considered to 
be appropriate to reach the objectives of this study. 
The oral administration 100 µCi (3.7 MBq) 14C-talazoparib yields an estimated effective 
radiation burden of 0.3 mSv and which is within the accepted limits of up to 1 mSv 
according to the International Commission on Radiological Protection (ICRP), 2007, 
Guidelines for Category 2a studies5,6. 
The Hungarian National Institute for Quality- and Organizational Development in 
Healthcare and Medicines (GYEMSZI) accepts an exposure of humans to ionizing 
radiation using unsealed radioactive products in human trials up to an effective dose of 
1 mSv (in adults), in accordance with national Hungarian standard MSZ 62-7 (2011)7, 
local regulations 16/2000 EüM and 23/1997 NM and EU guidance8.

1.2.2 
Unlabeled dose of talazoparib 
As of 30 Nov 2015, approximately 250 patients have received 1 mg of talazoparib once 
daily in multiple dose studies. Based on this experience, 1 mg QD was found to be 
sufficiently well-tolerated in the oncology population and is considered the 
recommended single-agent dose. As this study includes only a single dose, without the 
accumulation that occurs after multiple doses, the proposed 1 mg dose is expected to 
be generally well-tolerated. See the Investigator’s Brochure for additional details. 
1.2.3 
Study Population Rationale 
Talazoparib has shown clinical activity in advanced solid tumor patient populations and 
is being developed further as a treatment for several cancers; a mass balance study in 
cancer patients is thus justified. In the present study, the patient population will be 
limited to neoplastic diseases which were already included in previous clinical trials 
with talazoparib, i.e. patients with platinum-resistant ovarian carcinoma, cervical 
adenocarcinoma, small cell lung carcinoma and triple-negative breast cancer. After first 
administration of the 14C-labeled investigational medicinal product (IMP) and the 
completion of all assessments related to absorption, distribution, metabolism and 
excretion (ADME) and mass balance, select study subjects may have the option to 
continue treatment with daily unlabeled (non-radioactive) talazoparib in an open label 
extension study after evaluation by the Principal Investigator (PI) and approval of 
Sponsor; a separate extension protocol will be prepared for this purpose.

Overall Study Design and Plan 
3.1.1 
Type of Study 
This is a Phase 1, single-center, open-label, mass balance study with 14C-radiolabeled 
talazoparib in at least 6 patients with advanced solid tumors who qualify for treatment 
with talazoparib. Each eligible patient will receive an oral solution of 1 mg of talazoparib 
containing100 µCi of 14C-radiolabeled talazoparib. Patients who complete the mass-
balance part in this clinical study will have the option to continue treatment on an open-
label extension protocol (Figure 1). 
Figure 1 Study Design 
 
3.1.2 
Screening Period 
Patients will sign the study-specific informed consent form (ICF) prior to any 
study-specific screening procedures being performed within 21 days before dosing of 
talazoparib on Day 1. The written informed consent will be obtained for all patients, 
regardless of their eligibility for the study. 
Eligibility screening will consist of the assessments as presented in the schedule of 
assessments (Table 1). Patients may be enrolled if they are eligible according to the 
inclusion and exclusion criteria (Section 3.4). Details on the conduct of study-related 
assessments are given in Section 3.8.

3.1.3 
Treatment Period 
3.1.3.1 
Baseline 
Eligible patients will enter the clinical unit on Day –1 (one day before administration of 
talazoparib). Assessments will be performed as shown in the schedule of assessments 
(Table 1) and as detailed in Section 3.8. 
Once all baseline activities of Day –1 have been concluded and pending eligibility 
criteria have been confirmed patients will be eligible for enrollment and administration 
of talazoparib on Day 1. 
3.1.3.2 
Mass-Balance Part 
Patients will receive 1 mg of talazoparib as an oral solution that contains 100 µCi 
(3.7 MBq) of 14C-labeled talazoparib in the morning of Day 1. PK of radiolabeled 
compound will be performed together with potential metabolite profiling in blood, urine, 
feces as shown in Table 3. 
Assessments of safety and tolerability will be conducted according to the schedule of 
assessments (Table 1). 
Patients will be confined from Day –1 on and will be discharged from the study unit on 
Day 22 (504 h post-dose) after all study-related procedures have been concluded, 
assuming that the recovery of the radioactive material satisfies the conditions listed 
below (Section 3.1.3.3). 
3.1.3.3 
Early Discharge and Prolongation 
Patients will be discharged on Day 22, if any of the following conditions are met: 
• 
≥ 90% of the administered radioactivity is recovered in the urine and feces 
(accounting for radioactivity in vomitus, if applicable) 
• 
The daily total excreted radioactivity is 1% or less of the administered dose on 2 
consecutive days. Shipments for daily Quick Count will start on Day 10. 
Patients may be discharged on an individual basis prior to Day 22, if scintillation counts 
data are available and the above listed conditions are met. If the patient meet this early 
criteria prior to the morning of Day 22, collection of blood, urine, and feces may be 
stopped following completion of all scheduled 24-hour collections for that day. At the 
conclusion of the blood, urine, and feces collection, and completion of the same safety 
procedures as scheduled for Day 22 (in lieu of Day 22) the patients will be discharged. 
If an individual patient does not demonstrate a cumulative amount of radioactivity 
recovered in urine and feces ≥ 90% or has not met the daily total excretion criteria of 
1% or less of the administered dose on 2 consecutive days, following consultation with 
the Sponsor, the Investigator may ask patient to return to the clinic on Day 28 for a 
24 h collection of urine and feces (Table 2). If, by Day 29, the patient has still not met 
release criteria, a discussion between the Sponsor and the Investigator will be 
conducted for possibility to collect additional 24 h collection of urine and feces from 
Day 35 to Day 36 (Table 2).

3.1.3.4 
Follow-up 
Follow-up will be performed within 14 days after the last day of the mass balance 
phase and at least 30 days after Day 1, or the first day of extension protocol, whichever 
occurs first. This follow-up can be an onsite visit or a phone call (Table 1 and/or 
Table 2). 
3.2 
Extension Protocol 
Patients participating in this study with no clinically significant toxicities may be eligible 
to continue talazoparib treatment on a separate open-label extension protocol outside 
of this study. 
Decision to allow the patient to continue dosing with talazoparib in an open-label study 
will be based on potential clinical benefit and patient eligibility for enrollment to the 
open-label extension study. 
3.3 
Discussion of Study Design 
This is a clinical study to investigate the metabolism, excretion pattern, and mass 
balance of talazoparib following the administration of 14C-talazoparib. The terminal half-
life of talazoparib at 1 mg is approximately 2 days. Urine and feces collection for up to 
21 days should ensure that >90% of the dose is excreted. Talazoparib is being 
developed for the treatment of a variety of solid tumors either as a single agent or in 
combination with established therapies. No blinding, comparator treatment or 
randomization was considered necessary for this study. No formal sample size 
calculation has been carried out. The administration of the 14C-IMP is based on the 
ALARA principle (as low radioactive burden as reasonably achievable) set forth in the 
96/29/EURATOM directive. 
For dose justification and risk-benefit assessment, please see Section 1.2.

3.5 
Removal of Subjects from Therapy or Assessment 
Participation in the study is strictly voluntary. A patient has the right to withdraw from 
the study at any time for any reason. 
The Investigator has the right to terminate participation of a patient for any of the 
following reasons: 
• 
Occurrence of an exclusion criterion which is clinically relevant and affects the 
subject’s safety, if discontinuation is considered necessary by the Investigator 
and/or Sponsor 
• 
Intolerable toxicity as evidenced by the occurrence of severe AEs, or SAEs 
• 
Non-compliance that is likely to affect the validity of the data obtained from the 
subject. 
If a subject withdraws or is removed from further study participation end-of-treatment 
and follow-up visits will be conducted as described in Section 3.1.3.4. 
The main objectives of this study can be pursued after the dosing with the 
14C-radiolabeled drug on Day 1. Provided that the collection of the PK and 
mass-balance samples is completed, the subject will not be withdrawn from the main 
analysis. 
If a patient is withdrawn from the study, the Sponsor will be informed immediately. If 
there is a medical reason for withdrawal, the patient will remain under the supervision 
of the Investigator until satisfactory health has returned. 
Patients who discontinue before 85% of total drug is recovered from urine and feces 
may be replaced upon agreement of the Investigator and the Sponsor. 
The decision regarding the replacement of subjects will be documented. 
The Investigator will make every effort to ensure that non-completers and dropouts who 
have received study drug complete the safety follow-up assessments.

3.8.1.3.1 
Adverse Events 
Adverse events will be recorded following the first dose of study drug until completion 
of the follow-up visit. Any clinically significant observations in results of clinical 
laboratory, 12-lead ECGs, vital signs or physical examinations will be recorded as AEs. 
A treatment-emergent AE (TEAE) is defined as any event not present prior to 
administration of the study drug or any event already present that worsens in either 
severity or frequency following exposure to the study drug. 
Treatment-emergent safety data will be collected from Day 1 (the first and only dose of 
study drug) through 14 days after the last day of mass balance phase and at least 30 
days after Day 1 or before initiation of new cytotoxic chemotherapy, new investigational 
treatment, or the first day of extension protocol, whichever occurs first. 
An AE which occurs prior to (the first) administration of the study drug will be 
considered a pre-treatment AE and documented on the medical history eCRF. 
At several time points before and after drug administration, subjects will be asked 
non-leading questions to determine the occurrence of AEs. Subjects will be asked in 
general terms about any AEs at regular intervals during the study. In addition, all AEs 
reported spontaneously during the course of the study will be recorded. Events that 
meet serious criteria will be reported as detailed in Appendix 8.2. 
All answers will be coded by the Investigator using the Medical Dictionary for 
Regulatory Activities (MedDRA; most recent version) for AEs and will be recorded in 
the AEs Record. Details on the rating of the severity of the AEs and relationship to the 
study treatment are given in Appendix 8.2. 
Pregnancy of female subjects and female partners of male subjects will be monitored 
along with follow-up, if warranted (see also Appendix 8.3).

physical 
examinations may be conducted at any time per the Investigator’s discretion. 
3.8.1.4 
Total of Blood Volume 
During the course of this clinical study, a maximum volume of approximately 320 mL 
blood will be collected for PK and safety assessments. In this calculation a maximum 
prolonged observation period is taken into account (Section 3.1.3.3). 
If deemed necessary by the Investigator, additional blood samples for safety or PK 
analysis may be taken at additional (unscheduled) and follow-up visit(s) up to an 
additional volume of 30 mL. 
3.8.2 
Appropriateness of Measurements 
The assessments, which will be made in this study are standard for mass-balance 
studies, and generally recognized as reliable, accurate and relevant. 
3.8.2.1 
Timing of Assessments 
For PK, pre-dose samples will be obtained between waking up and dosing. Post-dose 
samples up to 60 minutes post-dose will be obtained with a time window of ±1 minute. 
From after 60 minutes until 12 hours post-dose, samples will be obtained with time 
margins of ±10 minutes. Thereafter, samples should be obtained within ±30 minutes of 
the scheduled time points. The ±30 minutes time window also applies to the start and 
end times of urine collection intervals. 
For safety, pre-dose assessments will be performed between waking up and dosing. 
Post-dose assessments will be performed with time margins of ±60 minutes of the 
planned scheme time. 
In the event assessments are planned for the same scheme time, the order of the 
assessments should be arranged in such a way that PK blood sampling will be done 
after the ECG and vital signs recordings have been conducted, with blood sampling 
exactly on time.

Analysis Populations 
3.9.1.1 
Safety Population 
All subjects who have received at least 1 dose of talazoparib. 
3.9.1.2 
Pharmacokinetic Population 
All subjects who have received talazoparib, including the radiolabeled IMP, and 
provided sufficient bioanalytical assessments to calculate reliable estimates of the PK 
parameters. The concentrations of talazoparib (and potential metabolites) in blood, 
urine and/or feces will be displayed for the safety population. 
3.9.2 
Statistical and Analytical Plan for Pharmacokinetic and Safety Evaluation 
An SAP will be generated by the Biostatistics Department of 
 the SAP will be 
finalized prior to database lock. Full details of the analysis to be performed will be 
included in the SAP. 
Any deviation from the SAP will be reported in the Section “Changes in Planned 
Analysis” in the Clinical Study Report. 
3.9.2.1 
Demographic and Other Baseline Characteristics 
Summary statistics (arithmetic mean, standard deviation, median, minimum and 
maximum for quantitative variables) will be presented. Frequency tables for qualitative 
data will be provided. Medical history findings will be summarized using MedDRA 
terms. 
3.9.2.2 
Pharmacokinetic Evaluation 
The concentration-times courses of total radioactivity in whole blood and plasma and of 
talazoparib in plasma and – if appropriate – of its metabolites in plasma will be 
separately tabulated. 
The following statistics will be calculated for each of the sampling points: arithmetic 
mean, standard deviation and coefficient of variation (CV), geometric mean, geometric 
standard deviation (re-transformed standard deviation of the logarithms),geometric CV, 
minimum, median, maximum value and the number of measurements. Concentrations 
below LLOQ will be set to zero when calculating descriptive statistics. Means at any 
post-dose time will only be reported if the mean ≥ LLOQ; for mean < LLOQ, “missing” is 
reported in the tables. In tables showing mean values, where values below LLOQ are 
included in the calculation of mean values, these means will be marked. 
Individual and geometric mean concentration vs time curves of total radioactivity in 
whole blood and plasma and of talazoparib in plasma and – if appropriate – of its 
metabolites in plasma (using the actual sampling times for individual plots and the 
planned sampling times for mean plots) will be plotted using both linear and 
semi-logarithmic scale. Post-dose concentrations < LLOQ will not be plotted; pre-dose 
concentrations < LLOQ will be set to zero. The amount (%) of talazoparib and – if 
appropriate – its metabolites excreted into urine and feces will be graphically illustrated

for each sampling interval as well as for the whole sampling period (bar charts for the 
individual data and for the arithmetic means including standard deviation). 
PK parameters of total radioactivity in whole blood and plasma and of talazoparib in 
plasma and of its metabolites in plasma (Tmax excluded) will be summarized by 
arithmetic mean, standard deviation and CV, geometric mean, geometric standard 
deviation, geometric CV, minimum, median, maximum value and the number of 
evaluable observations. The PK characteristics of Tmax will be described utilizing 
minimum, maximum and median as well as frequency counts. In calculation of PK 
parameters, pre-dose concentrations < LLOQ are set to zero; all post-dose 
concentrations < LLOQ are set as missing value. 
The same method will be used for the analysis of the drug related radioactivity in blood, 
plasma, urine and feces. Summary statistics and bar charts will be provided for the 
cumulative excretion of total radioactivity in urine, feces, vomitus (if applicable) and 
urine plus feces (plus vomitus [if applicable]) to assess mass balance of total 
radioactivity. 
For total radioactivity the ratio of whole blood to plasma based on AUC0-inf, Cmax and 
AUC0-last will be calculated and summarized. 
To determine the percentage of radioactivity associated with erythrocytes in whole 
blood over time (calculated only for time points that whole blood is collected), the 
following will be calculated: 
The amount of radioactivity in plasma versus whole blood, adjusted for the hematocrit, 
at the specific time points of comparison Xe/Xb= 1-[Cp*(1-Hct)/Cb], where Xe and Xb 
stand for amount of radioactivity in erythrocyte or plasma, respectively, and Cp and Cb 
stands for radioactivity concentration in plasma and blood, respectively. Hematocrit 
values for Days –1, 1 and 22 will be averaged for use in this calculation. 
Additional analyses of the concentrations of talazoparib and its metabolites (if 
applicable) in plasma, urine, and feces (vomitus, if applicable) as determined by radio-
chromatographic methods as well as the corresponding PK parameters will be reported 
under separate cover. 
3.9.2.3 
Evaluation of Safety and Tolerability 
All safety analyses will be performed using the safety population, defined as all patients 
who received talazoparib. Safety will be evaluated using summaries of AEs, physical 
examinations (and weight), vital signs, ECG recordings, and laboratory evaluations. 
3.9.2.3.1 
Adverse Events 
Adverse events will be coded to preferred term and system organ class using MedDRA 
and classified by severity using NCI CTCAE. The number and percentage of patients 
with AEs will be presented by MedDRA system organ class and preferred term, 
relationship to study treatment, severity, seriousness, and outcome (e.g. leading to 
permanent treatment discontinuation).

APPENDICES 
8.1 
Drug Accountability 
Upon receipt of the study drug, it will be inspected and counted by the Investigator or 
the responsible pharmacist. If necessary, all study drug will be re-packed per dosing 
occasion, and labeled according to 
 SOPs. 
The study drug will be kept in the 
 Pharmacy or in a locked and secured storage 
facility accessible only to those authorized by the Investigator to dispense the study 
drug. 
The responsible pharmacist will keep an inventory. This will include a description of the 
formulation and the quantity of study drug received for the study and a record of what is 
dispensed, to whom and when. 
Preparation of the study drug will be performed at 
 by a licensed expert on 
radioactivity. 
On termination of the study the Investigator or delegate will conduct a final inventory of 
the study drug supply and will record the results of this inventory in the Drug 
Accountability Form. Unused study drug will be returned to the Sponsor at the end of 
the study or will be locally destroyed according to 
 standard procedures. 
8.2 
(Serious) Adverse Events Evaluation and Reporting 
The safety management of this study will comply with all applicable national and 
international regulatory requirements and adhere to the full requirements of ICH 
Guidelines for Clinical Safety Data Management, Definitions and Standards for 
Expedited Reporting, Topic E2A (International Conference on Harmonization of 
Technical Requirements for Registration of Pharmaceuticals for Human Use, October, 
1994)15. 
8.2.1 
Adverse Events 
An AE is any unfavorable and unintended sign (including an abnormal laboratory 
finding), symptom, or disease temporally associated with the use of a medical 
treatment or procedure that may or may not be considered related to the medical 
treatment or procedure. AE definitions will be followed as stated in the ‘Note for 
Guidance on clinical safety data management: definitions and standards for expedited 
reporting’ (ICH topic E2A).15 
SAEs will be collected from the time the subject signs Informed Consent. Non-serious 
AEs will be collected from the time the subject receives first dose of study drug. 
The Investigator will report in the eCRF all AEs observed, spontaneously reported or 
noted (verbally or e.g. in a diary) by subjects. In addition, trial subjects will be 
questioned by site personnel about AEs at regular intervals using standard non-leading 
questions, such as "have you experienced anything new or different since your 
previous study visit?" 
Grading of severity, clinical significance, causality and seriousness will be determined 
by the Investigator using the CTCAE scale and will be reported in the eCRF.

8.2.2 
Grading of Severity 
The severity of AEs will be graded using the most current version of the Common 
Terminology Criteria for Adverse Events (CTCAE) 5-point scale16: 
• 
Mild (Grade 1): Asymptomatic or mild symptoms: clinical or diagnostic 
observations only; intervention not indicated. 
• 
Moderate (Grade 2): Minimal, local or non-invasive intervention indicated; limited 
age-appropriate instrumental activities of daily living (ADL). Intervention may or 
may not be indicated. 
• 
Severe (Grade 3): Medically significant but not necessarily life-threatening; 
severe is not the same as serious; determination of serious vs. life-threatening 
will be based upon subject’s condition / anticipated outcome, e.g. serious is 
usually reserved for an event which poses an immediate threat to subject’s life or 
could pose a threat to subject’s life if not treated promptly 
• 
Life-threatening (Grade 4): Life-threatening consequences; urgent intervention 
indicated. 
• 
Death (Grade 5) related to AE. 
It is emphasized that the term severe is a measure of severity: thus a severe AE is not 
necessarily “serious” as per regulatory definition. For example, itching for several days 
may be rated as severe, but may not meet regulatory definition of ‘serious’ 
(Section 8.2.3). 
8.2.2.1 
Grading of Relationship (Causality) 
The relationship of any AE to the study drug will be assessed and graded as related or 
not related as following: 
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). 
8.2.2.2 
Test results and physical examination findings 
Test findings and physical examination findings can result in AEs if they are: 
• 
Associated with accompanying symptoms 
• 
Requires additional diagnostic testing or medical/surgical intervention, and /

• 
Leads to a change in study dosing or discontinuation of the study medication; 
results in the addition of significant additional concomitant drug treatment or other 
therapy 
• 
Leads to any of the outcomes included in the definition of a SAE 
• 
Is considered to be an AE by the Investigator 
Reporting an AE should not be triggered by: 
• 
Merely needing to repeat an abnormal test, or, 
• 
Any abnormal test result that is determined to be an error, e.g. it is not 
reproducible or sustainable on repeat. 
8.2.3 
Serious Adverse Events 
An SAE is any untoward medical occurrence that, on the basis of medical and scientific 
judgment: 
• 
Results in death 
• 
Is life-threatening (This refers to an event in which the patient was at risk of 
death at the time of the event; it does not refer to an event which hypothetically 
might have caused death if it were more severe) 
• 
Requires inpatient hospitalization for a medical reason or prolongation of 
existing hospitalization (This refers to hospital admission required for treatment of 
the AE). 
Note: This does not include confinement in a skilled nursing unit; rehabilitation facility; the 
clinical research unit; or confinement due to a planned reason unrelated to study 
• 
Results in persistent or significant disability/incapacity 
• 
Is a congenital anomaly/birth defect 
• 
An important medical event (Medically Significant Event) that is considered by the 
Investigator to be serious but that may not be immediately life-threatening or result 
in death or hospitalization but may jeopardize the patient or may require intervention 
to prevent one of the other outcomes listed above. Examples of such events include 
but are not limited to intensive treatment in an Emergency Department or at the site 
for allergic bronchospasm, blood dyscrasias or convulsions that do not result in 
hospitalization. 
Medical and scientific judgment should be exercised in deciding whether expedited 
reporting is appropriate in other situations, such as important medical events that may 
not be immediately life-threatening or result in death or hospitalization but may 
jeopardize the patient or may require intervention to prevent one of the other outcomes 
listed in the definition above. These should also usually be considered serious. 
Examples of such events are intensive treatment in an emergency room or at home for 
allergic bronchospasm; blood dyscrasias or convulsions that do not result in 
hospitalization; or development of drug dependency or drug abuse. 
SAEs will be collected from the time the subject signs Informed Consent until 30 days 
post dosing. SAEs that are related to the investigational drug and continue beyond the 
normal collection period (i.e., are ongoing at the time a subject exits the study) will be

followed until resolution or until stabilized with sequelae. SAEs that begin after the 
subject’s participation in the study is complete, but that the Investigator considers to be 
related to study drug, may be reported at any time. 
The Investigator or clinical site personnel must notify Medivation’s vendor 
 and Medivation’s Medical Monitor of all SAEs, regardless of 
relationship to the investigational drug, within 24 hours of clinical site personnel 
becoming aware of the event. 
The Investigator will provide the initial notification by sending a completed “Serious 
Adverse Event Report Form”, which must include the Investigator’s assessment of the 
relationship of the event to investigational drug, and must be signed by the Investigator. 
In addition, notification is sent by the Investigator to the IEC, and the subject’s General 
Practitioner, if applicable. 
Follow-up information, or new information regarding an ongoing SAE, must be provided 
promptly as per all SAEs to Medivation’s vendor 
 and Medivation 
Medical Monitor. 
All SAE (initial and follow-up) reports should be sent to the SAE reporting contacts 
provided on Page 4. 
8.2.4 
Suspected Unexpected Serious Adverse Reactions 
A SAE the nature or severity of which is not consistent with the applicable product 
information (e.g., Investigator‘s Brochure for an unapproved investigational product or 
summary of product characteristics for an approved product) and which has reasonable 
relationship to IMP administration is called a Suspected Unexpected Serious Adverse 
Reaction (SUSAR). 
The Sponsor (Medivation Drug Safety) will determine which talazoparib SAEs meet 
regulatory reporting requirements as a SUSAR. Medivation Drug Safety will: 
1. 
Submit all SUSARs to the applicable local regulatory authority (Hungary) 
2. 
Issue SUSARs to 
 and/or Investigator whose responsibility will be to report the 
SUSAR to the applicable IEC 
Talazoparib SUSARs will derive from this study as well as other talazoparib clinical 
studies for cross-reporting to local regulatory authority. 
8.2.5 
Follow-up of Adverse Events 
Follow-up of AEs will continue until resolution, stabilization or death. In case of ongoing 
AEs at the moment of database closure, the data obtained at the moment of database 
closure will be used in the statistical analysis. The follow-up of the AE will be 
documented in the source documents and will be described in the final report only if 
considered relevant by the Investigator. 
8.3 
Pregnancy 
Pregnancies occurring up to 90 days after the completion of the study drug must be 
reported to the Investigator. The subject should be counseled by a specialist, to

discuss the risks of continuing with the pregnancy and the possible effects on the fetus. 
Monitoring of the subject should continue until the outcome of the pregnancy is known. 
The Investigator should report all pregnancies of female clinical study subjects to 
Medivation’s vendor 
 within 24 hours of becoming aware of them 
using the Pregnancy Reporting Form as per the contact information provided on 
Page 4: SAE Contact Information. 
If the Investigator becomes aware of a pregnancy occurring in the partner of a subject 
participating in the study, the pregnancy should be reported to Medivation’s vendor 
 within 24 hours of obtaining written consent from the pregnant 
partner. 
 must report all pregnancies (subject or subject partner) to the 
Sponsor. Pregnancy outcome will also be reported to the Sponsor within 24 hours of 
awareness. The Investigator will make arrangements for the partner to be counseled by 
a specialist, to discuss the risks of continuing with the pregnancy and the possible 
effects on the fetus. Monitoring of the partner should continue until the outcome of the 
pregnancy is known.
