PROTOCOL SYNOPSIS 
Protocol Title 
A Phase I Open-Label Pharmacokinetics and Safety Study of Talazoparib 
(MDV3800) in Patients With Advanced Solid Tumors and Normal or 
Varying Degrees of Renal Impairment 
Protocol # 
MDV3800-01/
/C3441001 
Indication 
Advanced solid tumors 
Study Duration 
x Accrual: approximately 18-24 months 
x Treatment: 1 cycle defined as 22 calendar days of daily oral intake 
of talazoparib (counted from day 1) regardless of any treatment 
hold.

Background and Rationale 
Talazoparib (PF-06944076; formerly known as BMN 673 or MDV3800) is a 
potent, orally bioavailable, small molecule poly(ADP-ribose) polymerase 
(PARP) inhibitor being developed for the treatment of a variety of human 
cancers both as single agent and in combination with other agents. PARP 
represents a family of at least 17 enzymes that transfer ADP-ribose 
groups to target proteins to regulate various cellular processes including 
deoxyribonucleic acid (DNA) repair. Among them, PARP1 and PARP2 play 
important roles in DNA repair. 
PARP inhibitors exert cytotoxic effects by 2 mechanisms:   
(1) inhibition of PARP1 and PARP2 catalytic activity  and,  
(2) PARP trapping, whereby PARP protein bound to a PARP inhibitor does 
not readily dissociate from DNA, preventing DNA repair, replication, and 
transcription.  
The single dose pharmacokinetic (PK) of talazoparib has been evaluated in 
a total of 5 clinical studies, of which 4 were conducted in cancer patients 
(Studies PRP-001, PRP-002, MDV3800-03, and MDV3800-14) and 1 in 
healthy subjects (Study 673-103). 
After administration of a single 1 mg dose of talazoparib capsules to 
cancer patients, the median time to reach maximum plasma 
concentration (Tmax) was ranging from 1.0 to 2.0 hours across studies. The 
geometric mean Cmax ranged from 4.35 to 8.79 ng/mL and the geometric 
mean area under concentration-time curve from time 0 to infinity (AUCinf) 
ranged from 116 to 196 ng•h/mL. Talazoparib was eliminated slowly with 
a mean terminal half-life (t½) of 89.8 hours. The talazoparib geometric 
mean apparent volume of distribution (Vz/F) values estimated ranged 
from 447 to 847 L, which is significantly greater than total body water (42 
L), indicating that talazoparib extensively distributes to peripheral tissues. 
The geometric mean apparent oral clearance (CL/F) values estimated for

talazoparib ranged from 5.12 to 7.71 L/hour (h). The geometric mean 
renal clearance (CLr) ranged from 2.76 to 3.44 L/h, indicating that urinary 
excretion was a major route of elimination for talazoparib. The PK of 
talazoparib was comparable between patients with cancer and healthy 
subjects. 
The PK of talazoparib following multiple oral daily doses was evaluated in 
a total of 5 studies in patients with cancer (Studies PRP-001, PRP-002, 
673-201, 673-301, and MDV3800-14) (Studies 673-201 and 673-301 only 
included sparse sampling). Following repeated 1 mg QD dosing to steady 
state, talazoparib was rapidly absorbed with a median Tmax ranging from 
approximately 1.0 to 2.0 h across studies. Talazoparib was eliminated 
slowly, with a geometric mean CL/F ranging from 4.80 to 5.53 L/h. The 
geometric mean CLr was 3.34 L/h and 3.32 L/h in Studies PRP-001 and 
PRP-002, respectively. The talazoparib geometric mean Cmax values ranged 
from 11.4 to 19.1 ng/mL and the geometric mean area under the 
concentration-time curve for a dosing interval (AUCW) values ranged from 
126 to 208 ng•h/mL. The talazoparib geometric mean steady-state pre 
dose plasma concentration (Ctrough) values ranged from 2.99 to 4.95 
ng/mL. 
Following repeated oral dosing, there was a dose proportional increase in 
the exposure of talazoparib (both Cmax and AUC0-24) across the dose 
range of 0.025 to 2 mg and the median talazoparib accumulation ratio 
(Rac) ranged from 2.23 to 12.3. Based on the multiple dosing data and 
consistent with its observed t½ of 89.8 h, talazoparib plasma 
concentrations reached steady state around 3 weeks after repeated daily 
dosing. 
The effect of food on the talazoparib plasma PK following administration 
of a single 0.5 mg dose of talazoparib oral capsule formulation in 18 
healthy subjects (Study 673-103). Food intake (a high-fat, high-calorie 
meal) had no impact on the AUC while reduced the Cmax by 46%. 
Consistent with findings from the food effect study, population PK 
analysis using data from Studies 673-301, 673-201, PRP-001, and PRP-002 
showed food intake decreased absorption rate but had no impact on the 
extent of the absorption. The reduction in the rate of absorption with 
food is not expected to be clinically relevant as efficacy is generally driven 
by total exposure.  Therefore, talazoparib can be taken without regard of 
food. 
Following oral administration of a single 1 mg dose of 14C-talazoparib to 
female patients with advanced solid tumors (Study MDV3800-03), a mean 
of 68.7% and 19.7% of the total administered radioactive dose was 
recovered in urine and feces, respectively. Excretion of unchanged 
talazoparib in urine was the major route of elimination accounting for 
54.6% of the administered dose, while unchanged talazoparib recovered 
in the feces accounted for 13.6%. No major circulating metabolites were 
identified in plasma, and talazoparib was the only circulating drug-derived

entity identified in plasma. No metabolites that individually represented 
more than 10% of the administered dose were recovered in the urine or 
feces. The identified metabolic pathways of talazoparib in humans 
include: 1) mono-oxidation; 2) dehydrogenation; 3) cysteine conjugation 
of mono-desfluoro-talazoparib; and 4) glucuronide conjugation. 
A population PK analysis for talazoparib was conducted to assess the 
impact of renal impairment on the CL/F using renal function as a 
categorical covariate defined by the baseline CLCR. The results of this 
analysis indicated that talazoparib CL/F was reduced by 14.4% and 37.1% 
in patients with mild renal impairment (CLCR, 60-89 mL/min) and 
moderate renal impairment (30 mL/min ч CLCR <60 mL/min), 
respectively, compared to that of patients with normal renal function 
(CLCR t90 mL/min). Due to limited number of severe renal impairment 
patients (CLCR <30 mL/min), the impact of severe renal impairment on 
talazoparib CL/F cannot be concluded. Therefore, based on this data, 
patients with moderate or severe renal impairment (CLCR < 60 mL/min) 
may be at risk of higher exposure to talazoparib. 
There is no study prospectively designed with the objective of assessing 
the potential effect of renal impairment on human PK of talazoparib, as 
most clinical studies exclude patients with renal impairment and 
especially those with severe dysfunction. 
The study will be carried out in patients with advanced solid tumors and 
with normal, mild, moderate or severe renal function as classified by 
estimated glomerular filtration rate (eGFR) according to the 2006 
Modification of Diet in Renal Disease (MDRD) study equation [available 
via www.mdrd.com].  
This study will contribute to understand the PK of talazoparib in patients 
with varying degrees of renal impairment and to better understand the 
exposure profiles in this patient population. Based on the results of this 
study, talazoparib dosing recommendations for patients with impaired 
renal function may be provided to future treating clinicians and potential 
exposure-dependent adverse events (e.g. myelosuppression) may be 
minimized. 
The dose selected in this study is 0.5 mg/day which is considered a safe 
dose as it is 50% lower than the Maximum Tolerated Dose (MTD) 
established in patients with solid tumors in phase 1 study at 1 mg/day. 
Talazoparib has also shown clinical activities at this dose level in a phase 1 
study; however efficacy is not being explored in this study. Additionally, 
the expected exposures increase in moderate and severe renal impaired 
patients should not exceed the exposure of maximum administered dose 
(MAD) of 2 mg/day experienced in the Phase 1 studies. Talazoparib will be

given daily for 22 calendar days in order to assess the safety and 
pharmacokinetics of talazoparib at the steady state. 
Objectives  
Primary objective:  
To investigate the effect of mild, moderate and severe renal impairment 
on the PK of talazoparib following daily oral dosing of talazoparib for 22 
calendar days in patients with advanced solid tumors. 
Secondary objectives: 
To evaluate the safety and tolerability of talazoparib in patients with 
advanced solid tumors and with normal, mild, moderate or severe renal 
impairment.  
Study Design 
This is an open-label, non-randomized, multi-center, phase 1 trial to 
investigate the PK and the safety of talazoparib in patients with advanced 
solid tumors and impaired renal function. 
Safety and PK data from patients with mild, moderate and severe renal 
impairment as classified using the MDRD study formula per FDA guidance, 
will be compared with a control group consisting of patients with normal 
renal function.  
The 4-variable 2006 MDRD equation, expressed as a single equation, is as 
follows:  
eGFR (mL/min/1.73 m
2
) = 175 x (Scr, std)
-1.154 
x (Age)
-0.203 
x (0.742 if female) x 
(1.212 if African American) 
 (where Scr, std = standardized serum Creatinine (mg/dL); age = years) 
Patients will be enrolled in parallel and will be assigned to one of four 
groups based on their renal function.  
Renal function defining each group according to the MDRD formula as 
follows: 
x Group 
A 
(control, 
normal 
renal 
function): 
eGFR 
ш 
90 
mL/min/1.73m2.  
x Group B (mild renal impairment): eGFR ш 60 and ч 89 
mL/min/1.73m2. 
x Group C (moderate renal impairment): eGFR ш30 and ч 59 
mL/min/1.73m2. 
x Group D (severe renal impairment): eGFR ш15 and ч 29 
mL/min/1.73m2, not on dialysis.  
In each group, 6 PK evaluable patients will be treated with daily oral doses 
of talazoparib 0.5 mg for 22 calendar days, regardless of any treatment 
hold. 
If enrollment in the group of patients with severe renal dysfunction

(Group D) is halted due to unacceptable toxicity, 2 additional evaluable 
patients will be enrolled in each of Groups A, B and C (total of 8 evaluable 
patients each). Therefore, a total of at least 24 patients will be enrolled in 
the study. 
Patients will be considered evaluable for PK analysis (PK evaluable) if they 
are eligible and have: 
x Completed 22 calendar days of treatment with talazoparib counted 
from Day 1, regardless of any treatment hold and missed 
ч 5 consecutive doses of  talazoparib, 
x Received at least 10 consecutive days of 0.5 mg talazoparib daily 
dose without dosing interruption prior to Day 22 PK sample 
collection, 
x Completed at least 85% of total plasma PK samples collection, 
x Not vomited talazoparib dose on Day 1 and Day 22 of the PK 
samples collection. 
Patients who discontinue the study prior to completion of Day 23 
assessments and/or who do not meet the above mentioned criteria may 
be replaced according to Sponsor´s judgment. 
On Day 1 and Day 22, serial PK plasma samples up to 24 hours post-dose 
will be collected for talazoparib concentration measurement.  
Note: 24h post-dose on Day 1 corresponds to the pre-dose of Day 2; 24h 
post-dose on Day 22 corresponds to Day 23. 
One PK blood sample will also be collected at the Safety Follow up Visit 
(End of Study Visit), if the study treatment discontinues earlier than 
planned.  
Additionally, trough (pre-dose) samples will be collected on Day 8 and Day 
15.  
Blood samples for plasma protein binding evaluation will be collected 2 h 
post-dose on Day 1 and Day 22.  
All voided urine will be collected after dosing on Day 1 and Day 22 
between the intervals of 0-12h and 12-24h. Pre-dose urine samples for PK 
analyses will be collected as a single void at pre-dose on Day 1.  
Patients with no clinically significant toxicities, no contraindications to 
continue treatment with talazoparib and no disease progression 
(underlying cancer progression) may be eligible to continue talazoparib 
treatment on a separate open-label extension study after discussion with 
the Principal Investigator and obtaining Sponsor permission. Sponsor 
decision to allow the patient to continue dosing with talazoparib in an 
open-label extension study will be based on potential overall benefit-risk, 
patient acceptance to be enrolled in the open-label extension study and 
other relevant criteria.

Study Treatment 
Talazoparib, 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 
(provided 
as 
the 
4-methylbenzenesulfonate 
[tosylate] salt).  
Talazoparib will be administered as 0.5 mg orally once daily for 22 days 
(Day 1 to Day 22).   
Efficacy Assessments 
Not applicable. Efficacy will not be evaluated in the study. 
Note: Screening tumor assessments will be obtained in the event that 
patients choose to continue talazoparib treatment on a separate open 
label extension protocol. 
Safety Assessments 
Safety assessments and tolerability of talazoparib will be monitored 
through the evaluation of adverse events (severity according to NCI-
CTCAE 
version 
4.03), 
clinical 
laboratory 
tests, 
vital 
signs, 
electrocardiograms (ECGs), ECOG and physical examinations at screening 
during the 22 days of duration of the study treatment until 30 days after 
the last study drug administration or before initiation of a new 
anticancer therapy (standard or investigational treatment) or the first 
day of the extension protocol whichever occurs first.   
All assessments will be scheduled as indicated in the Schedule of Visits 
and Assessments.  
PK Assessments 
Blood samples for PK: 
Plasma samples will be collected at predetermined time point. 
x Day 1 and Day 22: 
- Pre-dose:  
 
On Day 1: within 60 minutes prior to dose. 
 
On Day 22: 24h ±60 minutes from the previous dose (Day 21), 
but within 60 minutes prior to the next dose.  
- 0.5, 1, 2, 4, 6 h , between 8 and 12 h, and 24 h post-dose (i.e. total 
of 7 time points). 
Note: 24h post-dose on Day 1 corresponds to the pre-dose of Day 2; 24h 
post-dose on Day 22 corresponds to the sample on Day 23.  
Samples up to 60 minutes post-dose will be obtained with a window of ±3 
minutes. From after 60 minutes until 12 h post-dose, samples will be 
obtained with time margins of ±10 minutes. Thereafter, samples should 
be obtained within ±60 minutes of the scheduled time points.  
PK blood samples will be collected at the Safety Follow up Visit (End of

x Day 8 and Day 15: pre-dose samples only will be collected 24 h±60 
minutes from the previous dose, but within 60 minutes before the 
next dose on the day of sample collection. 
Blood samples for plasma protein binding evaluation: 
Blood samples for plasma protein binding evaluation will be collected at 
2h post-dose on Day 1 and Day 22. Samples will be obtained with a time 
margin of ±10 minutes. 
Urine Samples for PK:

and 12-24 h. A ±60 minute time window applies to the start and end 
times of urine collection intervals. 
Statistical Methods  
Population for Analysis:  
The safety population is defined as all patients who received any amount 
of talazoparib. 
The PK concentration population is defined as all eligible patients enrolled 
and treated who have at least 1 reportable plasma talazoparib 
concentration. 
The PK parameter analysis population is defined as all evaluable patients 
enrolled and treated who have at least 1 of the talazoparib PK parameters 
of primary endpoints interest. 
 
Sample size:  
6 PK evaluable patients will be enrolled per group. If enrollment in the 
group of patients with severe renal impairment (group D) is halted due to 
unacceptable toxicity, 2 additional evaluable patients will be enrolled in 
each Groups A, B and C (total of 8 evaluable patients each). Therefore, a 
total of at least 24 patients will be enrolled in the study. Patients who 
discontinue the study prior to completion of Day 23 assessment and/or 
who do not meet the PK evaluability criteria may be replaced if needed 
upon agreement of the Sponsor.   
 
Statistical Methods: 
x Safety Analysis: All safety analyses will be performed using the safety 
population. 
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 
(i.e., leading to permanent treatment discontinuation).   
Treatment-emergent safety data will be collected from Day 1 (the first 
dose of study drug) through 30 days after the last dose of study drug or 
before initiation of new anticancer therapy (standard or investigational

first.   
Laboratory values will be classified by severity using the NCI CTCAE.  
Laboratory shift tables of baseline results to each subsequent visit will 
be produced as appropriate. Change from baseline in laboratory values 
will be tabulated and summarized graphically. 
x Efficacy Analysis: No efficacy analysis is planned in this study, although 
baseline tumor assessments will be obtained in the event that patients 
choose to continue talazoparib treatment in a separate open-label 
extension study. 
 
PK Analysis: The PK parameters will be determined from the talazoparib 
concentration-time data.  PK parameters (AUC0-24, Cmax, AUC0-24,u, Cmax,u, 
Ctrough, Tmax, Fu, Rac, Ae%, and CLr ) will be calculated by non-
compartmental analysis using WinNonlin or another appropriate 
software. Additional PK parameters will be estimateded/calculated as 
applicable. PK parameters AUC0-24, Cmax, Cmax,u, and AUC0-24,u on Days 1 and 
22 will be natural log-transformed and analyzed using an analysis of 
variance (ANOVA) model with group as a fixed effect to compare each 
renal impairment group (mild, moderate or severe; Test) with the normal 
renal function group (Reference). Additionally, weight and age will be 
considered as covariates (at the significance level of 0.05). Estimates of 
the adjusted mean differences (Test - Reference) and corresponding 90% 
confidence intervals (CIs) for each comparison will be obtained from the 
model. The adjusted mean differences and 90% CIs for the differences will 
be exponentiated to provide estimates of the ratio of adjusted geometric 
means (Test/Reference) and 90% CIs for the ratios on the untransformed 
scale.  
Relationship between renal functional measures (e.g. eGFR) and selected 
PK parameters may be explored graphically, as appropriate. A regression 
line and 90% confidence region for the PK parameters and renal function 
will be included if appropriate. Vertical lines for the renal function group 
cut-off values will also be presented on the plots. Different symbols will 
be used to identify subjects from different renal function groups.  
Linear regression will be used to analyze the potential relationship 
between selected PK parameters and renal function. Estimates of the 
slope and, intercept, together with their precision (90% CI), and the 
coefficient of determination will be obtained from the model.

1. BACKGROUND AND RATIONALE 
1.1. 
Investigational Medicinal Product Overview 
1.1.1. 
Background 
Talazoparib (PF-06944076; formerly known as MDV3800 or BMN 673) is a potent, orally bioavailable, 
small molecule poly(adenosine diphosphate [ADP]-ribose) polymerase (PARP) inhibitor in development 
for the treatment of a variety of human cancers both as single agent and in combination with other 
agents. PARP represents a family of at least 17 enzymes that transfer ADP-ribose groups to target 
proteins to regulate various cellular processes including deoxyribonucleic acid (DNA) repair.  Among 
them, PARP1 and PARP2 play important roles in DNA repair.1 
PARP Inhibitors exert cytotoxic effects by 2 mechanisms: (1) inhibition of PARP1 and PARP2 catalytic 
activity, and (2) PARP trapping, whereby PARP protein bound to a PARP inhibitor does not readily 
dissociate from DNA, preventing DNA repair, replication, and transcription.2  
DNA instability is an important characteristic of many tumor types; often times a consequence of 
defects in DNA repair.3 Although a single DNA repair pathway defect may not be lethal to the cell, the 
combination of 2 pathway defects may be lethal. This process is termed synthetic lethality.4 PARP 
inhibitors induce synthetic lethality in tumor cells bearing mutations and/or deletions in genes involved 
in homologous recombination or other DNA repair pathways, including BRCA1, BRCA2, FANCA, PTEN, 
RAD51, MLH1, MSH2, ATM, MRE11, and PALB2.5–12  
Inhibition of PARP catalytic activity contributes to the process of synthetic lethality, as it results in 
persistent single-strand breaks that require homologous recombination DNA repair for survival. When 
trapped, PARP-DNA complexes inhibit DNA repair, replication, and transcription, and are more cytotoxic 
than unrepaired single-strand breaks because they do not readily dissociate. 
The antitumor properties of talazoparib have been demonstrated in nonclinical studies.7, 13 Talazoparib 
is more potent at inducing single-agent synthetic lethality of BRCA1- and BRCA2-deficient tumor cells in 
vitro than any other PARP inhibitors reported to date. Talazoparib inhibited growth of MX-1 human 
breast cancer cells (BRCA1-deficient) and Capan-1 human pancreatic cancer cells (BRCA2-deficient), with 
half- maximal inhibitory concentration (IC50) values of 0.3 nM and 5.0 nM, respectively.7 
Consistent with its antitumor effects in vitro, talazoparib demonstrated antitumor activity in xenograft 
tumor models in mice. Clinical development of talazoparib is ongoing in various solid tumors as 
monotherapy at the recommended dose of 1mg/day and in combination with other agents. 
1.1.2. 
Clinical Study Findings with Talazoparib 
As of 31 Juanuary 2018, approximately 659 patients and 18 healthy volunteers have received 
talazoparib at doses up to 2 mg/day in company-sponsored studies in hematologic malignancies and 
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. Data from this study demonstrated objective responses and/or 
clinical benefit in patients with breast, ovarian/peritoneal, and pancreatic cancer; small-cell lung cancer 
(SCLC); and Ewing sarcoma. A phase 2 and a phase 3 study evaluating single-agent talazoparib in

patients with locally advanced or metastatic breast cancer with deleterious germline BRCA mutations 
are ongoing.  
The adverse events (AEs) associated with talazoparib are generally identifiable through routine 
laboratory and clinical monitoring and may be managed by dose reduction or interruption. The most 
common AEs reported in patients treated with talazoparib as a single agent or in combination are 
myelosuppression (anemia, neutropenia, thrombocytopenia), gastrointestinal (GI) toxicity (nausea, 
vomiting, diarrhea), and fatigue. The most common AEs with a severity grade ш 3 as per the National 
Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) 
were 
myelosuppression.  
1.1.3. 
Pharmacokinetics of Talazoparib 
The single dose pharmacokinetic (PK) of talazoparib have been evaluated in a total of 5 clinical studies, 
of which 4 were conducted in cancer patients (Studies PRP-001, PRP-002, MDV3800-03, and MDV3800-
14) and 1 in healthy subjects (Study 673-103). 
After administration of a single 1 mg dose of talazoparib capsules to cancer patients, the median time to 
reach maximum plasma concentration (Tmax) was ranging from 1.0 to 2.0 hours (h) across studies. The 
geometric mean Cmax ranged from 4.35 to 8.79 ng/mL and the geometric mean area under 
concentration-time curve from time 0 to infinity (AUCinf) ranged from 116 to 196 ng•h/mL. Talazoparib 
was eliminated slowly with a mean t½ of 89.8 h. The talazoparib geometric mean apparent volume of 
distribution (Vz/F) values estimated ranged from 447 to 847 L, which is significantly greater than total 
body water (42 L), indicating that talazoparib extensively distributes to peripheral tissues. The geometric 
mean apparent oral clearance (CL/F) values estimated for talazoparib ranged from 5.12 to 7.71 L/h. The 
geometric mean renal clearance (CLr) ranged from 2.76 to 3.44 L/h indicating that urinary excretion was 
a major route of elimination for talazoparib. The PK of talazoparib was comparable between patients 
with cancer and healthy subjects. 
The PK of talazoparib following multiple oral daily doses was evaluated in a total of 5 studies in patients 
with cancer (Studies PRP-001, PRP-002, 673-201, 673-301, and MDV3800-14) (Studies 673-201 and 673-
301 only included sparse sampling). Following repeated 1 mg QD dosing to steady state, talazoparib was 
rapidly absorbed with a median Tmax ranging from approximately 1.0 to 2.0 h across studies. 
Talazoparib was eliminated slowly, with a geometric mean CL/F ranging from 4.80 to 5.53 L/h. The 
geometric mean CLr was 3.34 L/h and 3.32 L/h in Studies PRP-001 and PRP-002, respectively. The 
talazoparib geometric mean Cmax values ranged from 11.4 to 19.1 ng/mL and the geometric mean area 
under the concentration-time curve for a dosing interval (AUCW) values ranged from 126 to 208 
ng•h/mL. The talazoparib geometric mean steady-state pre dose plasma concentration (Ctrough) values 
ranged from 2.99 to 4.95 ng/mL. 
Following repeated oral dosing, there was a dose proportional increase in the exposure of talazoparib 
(both Cmax and AUC0-24) across the dose range of 0.025 to 2 mg and the median talazoparib 
accumulation ratio (Rac) ranged from 2.23 to 12.3. Based on the multiple dosing data and consistent 
with its observed t½ of 89.8 h, talazoparib plasma concentrations reached steady state around 3 weeks 
after repeated daily dosing.

The effect of food on the talazoparib plasma PK following administration of a single 0.5 mg dose of 
talazoparib oral capsule formulation in 18 healthy subjects (Study 673-103). Food intake (a high-fat, 
high-calorie meal) had no impact on the AUC while reduced the Cmax by 46%. Consistent with findings 
from the food effect study, population PK analysis using data from Studies 673-301, 673-201, PRP-001, 
and PRP-002 showed food intake decreased absorption rate but had no impact on the extent of the 
absorption.  The reduction in the rate of absorption with food is not expected to be clinically relevant as 
efficacy is generally driven by total exposure.  Therefore, talazoparib can be taken without regard of 
food. 
Following oral administration of a single 1 mg dose of 14C-talazoparib to female patients with advanced 
solid tumors (Study MDV3800-03), a mean of 68.7% and 19.7% of the total administered radioactive 
dose was recovered in urine and feces, respectively.  Excretion of unchanged talazoparib in urine was 
the major route of elimination accounting for 54.6% of the administered dose, while unchanged 
talazoparib recovered in the feces accounted for 13.6%. No major circulating metabolites were 
identified in plasma, and talazoparib was the only circulating drug-derived entity identified in plasma.  
No metabolites that individually represented more than 10% of the administered dose were recovered 
in the urine or feces. The identified metabolic pathways of talazoparib in humans include: 1) mono-
oxidation; 2) dehydrogenation; 3) cysteine conjugation of mono-desfluoro-talazoparib; and 4) 
glucuronide conjugation. 
At therapeutic exposures, talazoparib did not markedly induce or inhibit cytochrome P450 (CYP450) 
enzymes or transporters and is therefore unlikely to demonstrate clinically significant CYP450 inhibition- 
or induction-based drug-drug interactions or drug transporter inhibition-based drug-drug interactions 
when coadministered with corresponding substrates. However, talazoparib is a substrate for P-
glycoprotein (P-gp) and 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. 
Additional information on the chemistry, pharmacology, toxicology, preclinical findings, and clinical 
experience to date may be found in the talazoparib Investigator’s Brochure (IB). 
1.2. 
Study Rationale 
1.2.1. 
Rationale for Conducting the Study 
Based on the available data, talazoparib appears to predominantly be excreted via the renal route. A 
population PK analysis for talazoparib was conducted to assess the impact of renal impairment on the 
CL/F using renal function as a categorical covariate defined by the baseline CLCR. The results of this 
analysis indicated that talazoparib CL/F was reduced by 14.4% and 37.1% in patients with mild renal 
impairment (CLCR, 60-89 mL/min) and moderate renal impairment (30 mL/min ч CLCR <60 mL/min), 
respectively, compared to that of patients with normal renal function (CLCR t90 mL/min). Due to limited 
number of severe renal impairment patients (CLCR <30 mL/min), the impact of severe renal impairment 
on talazoparib CL/F cannot be concluded. Therefore, based on this data, patients with moderate or 
severe renal impairment (CLCR < 60 mL/min) may be at risk of higher exposure to talazoparib. 
There is no study prospectively designed with the objective of assessing the potential effect of renal 
impairment on human PK of talazoparib as most clinical studies exclude patients with renal impairment, 
and especially those with severe dysfunction. This study is designed to provide PK data following daily

administration of talazoparib in cancer patients with varying degrees of renal impairment. The study will 
be carried out in patients with advanced solid tumors with normal renal function and with mild, 
moderate and severe renal impairment classified by eGFR according to the 2006 Modification of Diet in 
Renal Disease (MDRD) study equation [available via www.mdrd.com] 14.  
This study will contribute to understand the PK of talazoparib in patients with varying degrees of renal 
impairment and to better understand the exposure profiles in this patient population. Based on the 
results of this study, talazoparib dosing recommendations for patients with impaired renal function may 
be provided to future treating clinicians and potential exposure-dependent adverse events (e.g. 
myelosuppression) may be minimized. 
1.2.2. 
Rationale for Regimen and Dose Selection 
In previous clinical trials, talazoparib was given as a single dose or as daily multiple doses in patients 
with various solid tumors and hematological malignancies in doses ranging from 0.025 to 2 mg/day 
given orally. The established recommended dose is 1 mg/day p.o. and at this dose, the mean t½ was 89.8 
hours. With daily administrations at this dose, it took approximately 3 weeks to reach the steady state. 
Based on this, a single dose study in cancer patients is not appropriate as at least a 2 to 3 week washout 
period would be required to be able to evaluate key PK parameters. In this study, talazoparib will be 
given daily for 22 calendar days to assess the pharmacokinetics and safety of talazoparib at steady state.  
The dose selected in this study is 0.5 mg daily, which is considered safe as it is 50% lower than the MTD 
established in patients with solid tumors in phase 1 study at 1 mg/day. Talazoparib has also shown 
clinical activity at the dose to be used in the study in a Phase 1 trial; however efficacy is not being 
explored in this study; only pharmacokinetics is being evaluated. Additionally, the expected exposures 
increase in moderate and severe renal impaired patients should not exceed the exposure of Maximum 
Administered Dose (MAD) of 2 mg/day experienced in the Phase I studies. 
2. OBJECTIVES 
2.1. 
Primary Objective 
To investigate the effect of mild, moderate and severe renal impairment on the PK of talazoparib 
following daily oral dosing of talazoparib for 22 calendar days in patient with advanced solid tumors.    
2.2. 
Secondary Objective 
To evaluate the safety and tolerability of talazoparib in patients with advanced tumors and with normal, 
mild, moderate or severe renal impairment. 
3. STUDY DESIGN 
This is an open-label, non-randomized, multi-center, phase 1 trial to investigate the PK and the safety of 
talazoparib in patients with various advanced solid tumors and impaired renal function. 
Safety and PK data from patients with mild, moderate and severe renal impairment as classified using 
the MDRD study formula per FDA guidance will be compared with a control group consisting of patients 
with normal renal function.  
The 4 variable 2006 MDRD formula, expressed as a single equation, is as follows:

-0.203 
x (0.742 if female) x (1.212 if African American) 
(where Scr, std = standardized serum Creatinine (mg/dL); age = years) 
Patients will be enrolled in parallel and assigned to one of four groups based on their renal function. 
Renal function defining each group according to the MDRD formula is as follows: 
x Group A (control, normal renal function): eGFR ш 90 mL/min/1.73m2.  
x Group B (mild renal impairment): eGFR ш 60 and ч 89 mL/min/1.73m2. 
x Group C (moderate renal impairment): eGFR ш30 and ч 59 mL/min/1.73m2. 
x Group D (severe renal impairment): eGFR ш15 and ч29 mL/min/1.73m2, not on dialysis.  
In each group, 6 PK evaluable patients will be enrolled. If enrollment in the group of patients with 
severe renal dysfunction (Group D) is halted due to unacceptable toxicity, 2 additional PK evaluable 
patients will be enrolled in each of Groups A, B and C (total of 8 PK evaluable patients each). 
Therefore, a total of at least 24 patients will be enrolled in the study from 9 sites.  
All patients will be treated with oral talazoparib given on a daily basis at a dose of 0.5 mg over 22 
calendar days (from Day 1 to Day 22 defined as 1 cycle of treatment) regardless of any study treatment 
hold. Talazoparib administration within this study will be discontinued after 22 days of starting study 
treatment. 
Note: At the End of Study, patients with no clinically significant toxicities, no contraindications to 
continue treatment with talazoparib, and no disease progression (underlying cancer progression) may be 
eligible to continue talazoparib treatment in a separate open-label extension study after discussion with 
the Principal Investigator and obtaining Sponsor permission. Sponsor decision to allow the patient to 
continue dosing with talazoparib in an open-label extension study will be based on potential overall 
benefit-risk, patient acceptance and other relevant criteria. 
Study periods include: 
x Screening 
x Enrollment (D-1) 
x A 22 calendar day treatment period 
x A Safety follow up visit (also considered as the End of Study visit) 
Serial PK plasma samples will be collected at predetermined times on Day 1 and Day 22 up to 24 h post-
dose (Day 23) for talazoparib concentration measurement. Additionally though (pre-dose) samples will 
be collected on Day 8 and Day 15.  
One PK blood sample will also be collected at the Safety Follow up Visit if the study treatment 
discontinues earlier than planned. Blood samples for plasma protein binding evaluation will be collected 
on Day 1 and Day 22 (2h post dose). Urine samples for PK analyses will be collected as a single void at 
pre-dose on Day 1 and all urine voided after talazoparib dosing on Days 1 and 22 between the intervals 
of 0-12 h and 12-24 h. 
Patients will be considered evaluable for PK analysis (PK evaluable) if they are eligible and have:

5. STUDY TREATMENT 
5.1. 
Study Treatment Identification 
Talazoparib is the only study treatment in the study and is considered an Investigational Medicinal 
Product (IMP). Talazoparib has the chemical name 
 
 
 
 
 The drug substance is a
 
 The drug product consists of the drug substance 
formulated with a pharmaceutically suitable excipient filled into hydroxymethylpropylcellulose capsules. 
For the purpose of this trial, the Single Reference Document to be used for talazoparib is the IB.  
5.2. 
Investigational Product Information and Management 
5.2.1. 
Packaging and Labelling 
The drug product will be provided as powder-filled, hard gelatin opaque white capsules containing 
talazoparib at the strength of 0.25 mg calculated as the free-base equivalent. Capsules will be provided 
free of charge by the Sponsor.  
The capsules will be supplied in 30-count induction-sealed high density polyethylene (HDPE) bottles with 
child-resistant caps. 
At minimum, each label typically provides the study protocol number, contents, and directions for use, 
storage directions, clinical trial statement, Sponsor name, batch/lot number, and product retest or 
expiration date. 
5.2.2. 
Storage and Dispensation 
At the site, talazoparib must be kept in the original container and stored safely and properly in 
accordance with the study drug label.    
Clinical supplies may not be used for any purpose other than that stated in the protocol. 
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. Patients should be advised that oral anticancer agents are toxic 
substances and that caregivers (other than the patient) should always use gloves when handling the 
capsules.  
Receipt and dispensing of trial medication must be recorded by an authorized person at the site. 
5.2.3. 
Accountability, Return and Destruction 
The Investigator is responsible for keeping accurate records of the clinical supplies received from the 
Sponsor or designee, the amount administered or dispensed to and returned by the patients, and the 
amount remaining at the conclusion of the trial. 
Patients must return all unused medication and empty containers to the Investigator.

Page 38 
The Investigator or designee must retain all unused or expired study supplies in a secure location 
(separately from medication that needs to be dispensed) for accountability and reconciliation by the 
Clinical Research Associate (CRA). 
Unused study drug will be destroyed on site, per the site’s standard operating procedures, ideally after 
the Sponsor or designee has granted approval for drug destruction and the CRA has accounted for all 
study drugs in a formal reconciliation process.  
If a site is unable to destroy study drug, the site can return unused study drug to a central location for 
drug destruction upon agreement with the Sponsor or designee.  
To ensure adequate records, dispensations, accountability, return / destruction of talazoparib capsules 
will be documented in a timely manner. Appropriate documents (Drug accountability/destruction log or 
similar) for this purpose will be provided. 
5.3. 
Study Treatment Administration 
5.3.1. 
Dosage and Administration 
The patient should start the study treatment within 3 calendar days after being enrolled in the study. As 
much as possible, study treatment should start on a weekday that allows D8, D15 and D22-23 visits to 
fall on a weekday. 
All patients enrolled will receive oral talazoparib given on a daily basis at a dose of 0.5 mg (2 capsules of 
0.25 mg) over 22 calendar days (from Day 1 to Day 22). 
At Day 1, all patients should be given with one bottle containing 30 capsules of talazoparib 0.25 mg. A 
resupply with a 2nd bottle containing 30 capsules of talazoparib 0.25 mg will occur at D15 for the 
remaining dosing period (D15-D22).   
Talazoparib should be taken at approximately the same time each day in the morning. The patients can 
self-administer talazoparib at home except on Days 1, 2, 8, 15 and 22. Patients should not take the study 
drug at home on Days 1, 2, 8, 15 and 22. On those days patients should be instructed to come into the 
clinic before taking his or her dose of talazoparib and these doses will be administered in the clinic by 
study staff after completing pre-dose visit assessments. If patient takes the study treatment at home on 
Day 22 before arriving at the clinic, the patient should be asked to visit the site again on Day 23 to take 
the study treatment at the clinic. All the study assessments (including PK sampling) initially planned on 
Day 22 should be collected on Day 23 instead. 
On Days 1 and 22 PK sampling days, talazoparib will be swallowed whole, under fasting conditions. 
Fasting is defined as after an overnight fast of at least 6 hours with no food allowed for at least 4 hours 
post-dose. Water is allowed as desired. On the other days, talazoparib can be given with or without 
food.  
If a patient vomits a dose, the patient should not take a second dose that calendar day. The patient 
should resume daily dosing the following day. If a patient misses a dose, he/she should take the dose as 
soon as possible, but not when more than 12 hours after the missed scheduled dose. If the dose is 
missed greater than 12 hours, the missed dose should be skipped and the patient should take the next 
dose when scheduled.

Page 39 
If a capsule is broken or damaged, the capsule should not be used, and brought back to the site for 
accountability and disposal. 
5.3.2. 
Treatment Compliance 
Patients will be instructed to bring all used and unused study drug containers and their completed study 
drug diary to all clinic visits (Day 8, Day 15 and Day 22) in order to assess the treatment compliance. Site 
staff will perform accountability of the returned drug and will assess compliance of the patient. Site staff 
must ensure that the patient clearly understands the directions for self-medication and follows the 
schedule adequately. 
5.3.3. 
Treatment Duration 
The patients will be treated only during 1 cycle, defined as a 22 calendar days counted from Day 1, 
regardless of any treatment hold.  
If Day 22 coincides with a non-working day (e.g. weekend, holiday) it is acceptable to administer study 
treatment for more than 22 calendar days up until the closest upcoming weekday, up to a maximum of 
25 days of treatment. 
Patients with no clinically significant toxicities, no contraindications to continue treatment with 
talazoparib and no disease progression (underlying cancer progression) may be eligible to continue 
talazoparib treatment on a separate open-label extension study after discussion with the Principal 
Investigator and obtaining Sponsor permission. Sponsor decision to allow the patient to continue dosing 
with talazoparib in an open-label extension study will be based on potential overall benefit-risk, patient 
acceptance to be enrolled in the open-label extension study and other relevant criteria. 
5.4. 
Treatment Schedule Adjustment and Adverse Event Management 
5.4.1. 
General Rules 
Regular assessment and monitoring of AEs is required throughout study treatment period and until the 
Safety Follow up visit, i.e. 30 days after the last dose of study drug or before initiation of a new 
anticancer therapy (standard or investigational treatment) or the first day of the extension protocol 
whichever occurs first. 
Toxicity will be assessed utilizing the National Cancer Institute Common Terminology Criteria for Adverse 
Events (NCI CTCAE) v4.03. For adverse event terms not specifically listed in the NCI CTCAE, the 
investigator should report the adverse event using the criteria in Table 1 to assess severity. 
Table 1: AE grading for toxicities when the AE term is not listed in NCI CTCAE 
Grade 
Description

Death related to AE. 
 
Patients will be instructed to notify their study Investigator immediately for any and all toxicities. 
Assessment of causality (chronology, confounding factors, concomitant medications, diagnostic tests, 
and previous experience with the study treatment) should be conducted by the Investigator prior to 
dose modification and/or delay whenever possible. As a general approach, it is suggested that all AEs be 
managed with supportive care at the earliest signs of toxicity and before delaying/reducing study drug, 
when possible and if clinically appropriate.

x Serum total immunoglobulin IgG, antinuclear antibody (ANA), antismooth muscle antibody, liver kidney 
microsomal antibody 1 (LKM1), and liver cytosol type 1 antibodies (L-C-1) to assess for autoimmune 
hepatitis  
x Serum acetaminophen (paracetamol) concentration 
Obtain a more detailed history: 
x Prior and concurrent diseases or illness  
x Exposure to environmental and/or industrial chemical agents  
x Symptoms (if applicable) including right upper quadrant pain, hypersensitivity-type reactions, fatigue, 
nausea, vomiting, and fever  
x Prior and concurrent use of alcohol, recreational drugs, and special diets  
x Concomitant use of medications (including nonprescription medicines and herbal and dietary 
supplements), plants, and mushrooms  
x Obtain viral serologies for hepatitis A, B, C, and E (D if positive for hepatitis B), cytomegalovirus,

x Serology for celiac disease  
x Serum alpha-1 antitrypsin  
x Creatine phosphokinase (CPK), haptoglobin, lactate dehydrogenase (LDH), and peripheral blood smear  
x Appropriate liver imaging  
x Hepatology consult (liver biopsy may be considered in consultation with a hepatologist) 
 
The investigator and the Sponsor should discuss and agree with any decision to re-challenge. Following 
re-challenge, patients should be closely monitored for signs and symptoms of hepatitis and/or abnormal 
liver test results. If signs or symptoms recur with re-challenge, study drug should be permanently 
discontinued. Re-challenge should never occur if the criteria for permanent discontinuation are clearly 
met.

4. 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 (e.g. 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 talazoparib should be withheld or permanently discontinued as 
appropriate for the safety of the patient. When talazoparib 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 5 
should be performed.

Study Treatment Discontinuation 
By default, patients are treated for 22 calendar days counted from day 1, regardless of any treatment 
hold. The Investigator will discontinue study treatment before Day 22 if any of the following conditions 
are met: 
x Patient’s decision to withdraw study treatment 
x Intercurrent illness or a change in patient´s condition or unacceptable toxicity that warrants study 
treatment discontinuation according to Investigator judgment 
x Any event, condition, criterion which would warrant treatment discontinuation according to 
section 5.4 
x Need for additional local and/or systemic non-protocol anticancer therapy or patient receives 
non-protocol anticancer therapy at any time during the study treatment.  
x Progressive Disease 
x Lost to follow up 
x Death 
x Pregnancy 
x Investigator’s decision 
x Medical Monitor’s decision 
x Sponsor’s discontinuation of the study 
Permanent treatment discontinuation is defined as permanent cessation of study drug administration.  
After permanent treatment discontinuation, a Safety Follow up Visit (End of Study visit) will be 
performed. The Safety Follow up Visit corresponds to the end of study participation.  
6. CONCOMITANT TREATMENT AND PROCEDURES 
Concomitant therapy includes any medication (e.g. prescription drugs, over-the-counter drugs, 
herbal/homeopathic remedies, nutritional supplements, etc.) used by a patient from 28 days prior to 
enrollment until 30 days after the last dose of study drug or the first day of extension study whichever 
occurs first. Any concomitant medication during the study will be recorded on the eCRF. 
In the event of an emergency, any needed medications (even if prohibited per section 6.3) may be 
prescribed as required, but the 
 Medical Monitor or designee must be notified of the use of any 
prohibited medication immediately thereafter.  
The following sections and Table 6 provide a list of allowed and prohibited medications and instructions 
on their use. 
6.1. 
Allowed Concomitant Treatments 
The Investigator may prescribe concomitant medications during the study as clinically indicated; as long 
as the prescribed medication is not prohibited by the protocol (refer to section 6.3). Allowed 
medications include (but are not limited to): 
x Anti-emetics, such as dexamethasone, metoclopramide, ondansetron, aprepitant, etc.; anti-
diarrheals, such as loperamide hydrochloride; appetite stimulants such as megestrol acetate.

x Supportive medications may be provided prophylactically or therapeutically at the Investigator’s 
discretion, with the exception of that colony stimulating factor (G-CSF or GM-CSF) and 
erythropoiesis-stimulating agents that are only allowed in the rescue setting (not for primary or 
secondary prophylaxis). Erythropoietin is allowed if the patient is chronically receiving this drug. 
x Bisphosphonates and the monoclonal antibody denosumab are also permitted for treatment, or 
prophylaxis, of bone metastases as per local standards of care.  
6.2. 
Concomitant Medication for Treatment of Renal Impairment 
If the patient is taking concurrent medications for treatment of renal impairment, to be eligible he/she 
must meet inclusion criterion 10. Also, concurrent medication used for the management of renal 
impairment will not be taken for at least 4 hours before and 2 hours after talazoparib dosing. During 
that period, the patient should not take these medications. 
6.3. 
Prohibited Treatments 
Patients are prohibited from receiving the following therapies from the time of patient informed 
consent form (PICF) until the Safety Follow up Visit (End of Study visit): 
x Investigational agents other than talazoparib; 
x Any additional investigational or commercial anticancer agents, such as chemotherapy,

7. STUDY VISITS AND ASSESSMENTS 
7.1. 
Patient Inclusion  
7.1.1. 
Informed Consent 
In compliance with the Declaration of Helsinki, ICH E6 (Section 4.8), US 21 CFR §50 and other applicable 
local regulations, a properly written and executed (PICF will be obtained for each patient prior to 
entering the patient into the study. 
Prior to any study-specific screening evaluation, the patient or legally acceptable representative (if 
applicable per local regulation) will be informed of the nature of the study and will be given pertinent 
information as to the intended purpose, possible benefits, and possible adverse experiences. A legally 
acceptable representative is an individual or other body authorized under applicable law to consent, on 
behalf of a prospective patient, to the patient’s participation in the study. 
An approved PICF will then be read and signed by the patient (or legally acceptable representative if 
applicable) and, when required, a witness, and the Investigator or a person designated by the 
Investigator, as per local regulations. The patient will be provided with a copy of the signed PICF. 
The patient may withdraw from the study at any time without prejudicing future medical treatment. In 
any case, the withdrawal should be clearly documented in the medical charts of the patient.   
If a potential patient or legally acceptable representative is illiterate or visually impaired, the 
Investigator must provide an impartial witness to read the PICF to the patient and must allow for 
questions. Thereafter, both the patient or legally acceptable representative and the witness must sign 
the PICF to attest that informed consent was freely given and understood. The PICF will include a 
statement by which the patient allows the Sponsor’s duly authorized personnel, the Ethics Committee 
(IRB), and the regulatory authorities to have direct access to its data that will be processed according to 
the confidentiality regulations.  
If important new information becomes available that may be relevant to the patient’s consent and 
willingness to continue participation in the study, the PICF will be revised and submitted to IRB for 
approval/favorable opinion. The new information will be then discussed with the patient in a timely 
manner and if he/she agrees to continue participation in the study, the revised PICF will be signed and 
dated and the patient will receive a copy. 
In line with each country’s applicable regulations, the source should also support the documentation of 
the consent process, for each patient. 
Note: If the patient continues the treatment in the context of the extension study (separate protocol), a 
new PICF will be obtained.

Patient Enrollment  
Details on the process to be followed to enroll the patient in the study can be found in the Registration 
Eligibility Review and Enrollment Instruction Manual provided to each site. 
Patients will be enrolled in one of the four groups based on their renal function, according to section 
4.1.  
Study treatment should be started within 3 calendar days after enrollment. 
7.2. 
Schedule of Visits and Assessments 
Prior to undergoing any study specific procedures not considered standard practice by the institution, 
patients must read and sign the PICF. Adherence to the schedule of visits and assessments is required 
and visits should be planned accordingly.  
All study visits and procedures are detailed in the Schedule of Visits and Assessments table presented in 
this section. All study procedures and assessment should be performed irrespective of any treatment 
hold.

Blood PK samples  
Blood samples for PK analyses will be drawn at the following selected time-points: 
x Day 1 and Day 22: 
o Pre-dose: 
 On Day 1: within 60 minutes prior to dose 
 On Day 22: 24h ± 60 minutes from the previous dose (Day 21) but within 60 minutes 
prior to the next dose 
o Post dose: 0.5, 1, 2, 4, 6 h, between 8 and 12 h, and 24 h after taking talazoparib. Post-
dose samples up to 60 minutes post-dose will be obtained with a window of ± 3 minutes. 
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 ± 60 minutes of 
the scheduled time points. 
Note: the 24h post -dose sample on Day 1 corresponds to the pre-dose sample on Day 2 and the 
24h post-dose sample on Day 22 corresponds to the sample on Day 23. 
x Day 8 and Day 15: Pre-dose samples will be collected 24h ± 60 minutes from the previous dose 
but within 60 minutes before the next dose on the day of sample collection. 
Note: One PK Blood sample will also be collected at the safety follow up if the study treatment 
discontinues earlier than planned. 
7.4.7.2. 
Urine PK samples 
Urine samples for PK analyses will be collected as follows: 
x As a single void at pre-dose on Day 1 
x All urine voided after talazoparib dosing on Day 1 and Day 22 will be collected between the 
intervals of 0-12 h and 12-24 h. A ± 60 minute time window applies to the start and end times of 
urine collection intervals. 
7.4.7.3. 
Blood samples for plasma protein binding evaluation 
Blood samples for plasma protein binding evaluation will be collected at 2h post-dose on Day 1 and Day 
22. A ± 10 minute window will apply.

7.5. 
Permanent Patient Discontinuation 
The Investigator has the right to withdraw a patient from the study at any time. In addition, patients 
have the right to withdraw from the study at any time for any reason. 
Permanent treatment discontinuation is defined as permanent cessation of study drug administration. 
After permanent discontinuation, a Safety Follow Up Visit (End of Study Visit) will be performed.   
The Safety Follow Up Visit corresponds to the End of Study participation.  
Should a patient decide to withdraw consent, all efforts will be made to complete and report the 
observations as thoroughly as possible. The Investigator should contact the patient by telephone or 
through a visit to establish as completely as possible the reason for the withdrawal. A complete final 
evaluation at the time of the patient’s withdrawal should be made with an explanation of why the 
patient is withdrawing from the study. Withdrawal should be documented on the initial PICF, and must 
be dated and signed by the patient and by the Investigator 
In the case a patient does not show up for study visits, site staff should make reasonable contact 
attempts before declaring the patient as lost to follow-up. These attempts need to be documented in 
the medical records.  
8. ADVERSE EVENT REPORTING 
8.1. 
Requirements 
Table 9 below summarizes the requirements for recording safety events on the CRF and for reporting 
safety events on the Serious Adverse Event (SAE) Report Form to Pfizer Safety. These requirements are 
delineated for 3 types of events: (1) SAEs; (2) non-serious adverse events (AEs); and (3) exposure to the 
investigational product under study during pregnancy or breastfeeding, and occupational exposure.

All observed or volunteered events regardless of treatment or suspected causal relationship to the 
investigational product(s) will be reported as described in the following paragraphs. 
Events listed in Table 9 above that require reporting to Pfizer Safety on the SAE Report Form within 24 
hours of awareness of the event by the investigator are to be reported regardless of whether the event 
is determined by the investigator to be related to an investigational product under study. In particular, 
if the SAE is fatal or life-threatening, notification to Pfizer Safety must be made immediately, 
irrespective of the extent of available event information. This time frame also applies to additional new 
(follow-up) information on previously forwarded reports. In the rare situation that the investigator does 
not become immediately aware of the occurrence of an SAE event, the investigator must report the 
event within 24 hours after learning of it and document the time of his/her first awareness of the event. 
For each event, the investigator must pursue and obtain adequate information both to determine the 
outcome and to assess whether it meets the criteria for classification as an SAE (see section 8.2.4 
below).  
In addition, the investigator may be requested by Pfizer Safety to obtain specific follow-up information 
in an expedited fashion. This information is more detailed than that recorded on the CRF. In general, this 
will include a description of the event in sufficient detail to allow for a complete medical assessment of 
the case and independent determination of possible causality. Any information relevant to the event, 
such as concomitant medications and illnesses, must be provided. In the case of a patient death, a 
summary of available autopsy findings must be submitted as soon as possible to Pfizer Safety. Any 
pertinent additional information must be reported on the SAE Report Form; additional source 
documents (eg, medical records, CRF, laboratory data) are to be sent to Pfizer Safety ONLY upon 
request.

Page 62 
As part of ongoing safety reviews conducted by the sponsor, any non-serious AE that is determined by 
the sponsor to be serious will be reported by the sponsor as an SAE. To assist in the determination of 
case seriousness, further information may be requested from the investigator to provide clarity and 
understanding of the event in the context of the clinical study. 
8.1.1. 
Additional Details On Recording Adverse Events on the CRF 
All events detailed in the table above will be recorded on the AE page(s) of the CRF.  It should be noted 
that the SAE Report Form for reporting of SAE information is not the same as the AE page of the CRF.  
When the same data are collected, the forms must be completed in a consistent manner. AEs should be 
recorded using concise medical terminology and the same AE term should be used on both the CRF and 
the SAE Report Form for reporting of SAE information. 
8.1.2. 
Eliciting Adverse Event Information 
The investigator is to record on the CRF all directly observed AEs and all AEs spontaneously reported by 
the study patient.  
In addition, each study patient will be questioned about the occurrence of AEs in a non-leading manner. 
8.1.3. 
Withdrawal From the Study Due to Adverse Events (see sections 5.5 and 7.5) 
Withdrawal due to AEs should be distinguished from withdrawal due to other causes, according to the 
definition of AE noted below, and recorded on the CRF.  
When a patient withdraws from the study because of an SAE, the SAE must be recorded on the CRF and 
reported, as appropriate, on the SAE Report Form, in accordance with section 8.1 above. 
8.1.4. 
Time Period for Collecting AE/ Information 
The time period for actively eliciting and collecting AEs and SAEs (“active collection period”) for each 
patient will be as per the Table below:

8.1.4.1. 
Reporting SAEs to Pfizer Safety 
All SAEs occurring in a patient during the active collection period are reported to Pfizer Safety on the 
SAE Report Form.  
SAEs occurring in a patient after the active collection period has ended are reported to Pfizer Safety if 
the investigator becomes aware of them; at a minimum, all SAEs that the investigator believes have at 
least a reasonable possibility of being related to investigational product must be reported to Pfizer 
Safety. 
Follow up by the investigator continues throughout and after the active collection period and until the 
event or its sequelae resolve or stabilize at a level acceptable to the investigator, and Pfizer concurs with 
that assessment. 
If a patient begins a new anticancer therapy, SAEs occurring during the above-indicated active collection 
period must still be reported to Pfizer Safety irrespective of any intervening treatment. 
8.1.4.2. 
Recording Non-serious AEs and SAEs on the CRF 
During the active collection period, both non-serious AEs and SAEs are recorded on the CRF. 
Follow-up by the investigator may be required until the event or its sequelae resolve or stabilize at a 
level acceptable to the investigator, and Pfizer concurs with that assessment. 
If a patient begins a new anticancer therapy, the recording period for non-serious AEs ends at the time 
the new treatment is started; however, SAEs must continue to be recorded on the CRF during the 
above-indicated active collection period.

8.1.5. 
Causality Assessment 
The investigator’s assessment of causality must be provided for all AEs (serious and non-serious); the 
investigator must record the causal relationship on the CRF, and report such an assessment in 
accordance with the SAE reporting requirements, if applicable. An investigator’s causality assessment is 
the determination of whether there exists a reasonable possibility that the investigational product 
caused or contributed to an AE; generally the facts (evidence) or arguments to suggest a causal 
relationship should be provided.  If the investigator does not know whether or not the investigational 
product caused the event, then the event will be handled as “related to investigational product” for 
reporting purposes, as defined by the sponsor.  If the investigator's causality assessment is “unknown 
but not related” to investigational product, this should be clearly documented on study records.  
In addition, if the investigator determines that an SAE is associated with study procedures, the 
investigator must record this causal relationship in the source documents and CRF, and report such an 
assessment in the dedicated section of the SAE Report Form and in accordance with the SAE reporting 
requirements. 
8.1.6. 
Sponsor’s Reporting Requirements to Regulatory Authorities 
AE reporting, including suspected unexpected serious adverse reactions, will be carried out in 
accordance with applicable local regulations. 
8.2. 
Definitions 
8.2.1. 
Adverse Events 
An AE is any untoward medical occurrence in a study patient administered a product or medical device; 
the event need not necessarily have a causal relationship with the treatment or usage.  Examples of AEs 
include, but are not limited to:  
x Abnormal test findings; 
x Clinically significant signs and symptoms; 
x Changes in physical examination findings; 
x Hypersensitivity; 
x Drug abuse; 
x Drug dependency. 
Additionally, AEs may include signs and symptoms resulting from: 
x Drug overdose; 
x Drug withdrawal; 
x Drug misuse;  
x Drug interactions; 
x Extravasation;

x Exposure during pregnancy (EDP); 
x Exposure via breastfeeding; 
x Medication error; 
x Occupational exposure. 
Worsening of signs and symptoms of the malignancy under study should be recorded as an AE in the 
appropriate section of the CRF. Disease progression assessed by measurement of malignant lesions on 
radiographs or other methods should not be reported as AEs. 
8.2.2. 
Adverse Event of Special Interest (AESI) 
AESIs include a diagnosis of MDS or AML (consistent with events observed with talazoparib) and 
abnormal liver test results.   
Liver test abnormalities that require reporting are the following: 
x 
AST or ALT ш 3 times ULN (> 5 × ULN if baseline ALT/AST is > 3 × ULN) and total bilirubin > 
2 times ULN or INR > 1.5 
x 
AST or ALT ш 3 times ULN with signs and symptoms consistent with hepatitis and/or 
eosinophilia (ш 500 eosinophils/ђL) 
Tissue samples and any other supporting data used to enable the diagnosis of MDS or AML should be 
submitted for central review if requested. 
AESIs must be transmitted to Pfizer Safety Unit by completing a SAE form. 
8.2.3. 
Abnormal Test Findings 
Abnormal objective test findings should be recorded as AEs when any of the following conditions are 
met:  
x 
Test result is associated with accompanying symptoms; 
x 
Test result requires additional diagnostic testing or medical/surgical intervention;  
x 
Test result leads to a change in study dosing (outside of any protocol-specified dose 
adjustments) or discontinuation from the study, significant additional concomitant drug 
treatment, or other therapy; and/or, 
x 
Test result is considered to be an AE by the investigator or sponsor. 
Merely repeating an abnormal test, in the absence of any of the above conditions, does not constitute 
an AE. Any abnormal test result that is determined to be an error does not require recording as an AE. 
8.2.4. 
Serious Adverse Events 
A serious adverse event is any untoward medical occurrence at any dose that:

x 
Results in death; 
x 
Is life-threatening (immediate risk of death); 
x 
Requires inpatient hospitalization or prolongation of existing hospitalization; 
x 
Results in persistent or significant disability/incapacity (substantial disruption of the 
ability to conduct normal life functions); and, 
x 
Results in congenital anomaly/birth defect. 
Or that is considered to be: 
x 
An important medical event 
Medical and scientific judgment is exercised in determining whether an event is an important medical 
event. An important medical event may not be immediately life-threatening and/or result in death or 
hospitalization.  However, if it is determined that the event may jeopardize the patient or may require 
intervention to prevent one of the other AE outcomes, the important medical event should be reported 
as 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; development of 
drug dependency or drug abuse; or the diagnosis o fa second primary malignancy. 
x 
Progression of the malignancy under study (including signs and symptoms of progression) 
should not be reported as an SAE unless the outcome is fatal within the active collection 
period.  
x 
Hospitalization due to signs and symptoms of disease progression should not be reported as an 
SAE.  
x 
If the malignancy has a fatal outcome during the study or within the active collection period, 
then the event leading to death must be recorded as an AE on the CRF, and as an SAE with 
Common Terminology Criteria for Adverse Events (CTCAE) Grade 5 (see section 8.3). 
8.2.5. 
Hospitalization 
Hospitalization is defined as any initial admission (even less than 24 hours) in a hospital or equivalent 
healthcare facility, or any prolongation of an existing admission.  Admission also includes transfer within 
the hospital to an acute/intensive care unit (e.g. from the psychiatric wing to a medical floor, medical 
floor to a coronary care unit, or neurological floor to a tuberculosis unit).  An emergency room visit does 
not necessarily constitute a hospitalization; however, the event leading to the emergency room visit is 
assessed for medical importance. 
Hospitalization does not include the following: 
x 
Rehabilitation facilities; 
x 
Hospice facilities;

x 
Respite care (eg, caregiver relief); 
x 
Skilled nursing facilities; 
x 
Nursing homes; 
x 
Same-day surgeries (as outpatient/same-day/ambulatory procedures). 
Hospitalization or prolongation of hospitalization in the absence of a precipitating clinical AE is not in 
itself an SAE. Examples include:  
x 
Admission for treatment of a preexisting condition not associated with the development of a 
new AE or with a worsening of the preexisting condition (eg, for workup of a persistent 
pretreatment laboratory abnormality); 
x 
Social admission (eg, patient has no place to sleep); 
x 
Administrative admission (eg, for yearly physical examination); 
x 
Protocol-specified admission during a study (eg, for a procedure required by the study 
protocol); 
x 
Optional admission not associated with a precipitating clinical AE (eg, for elective cosmetic 
surgery); 
x 
Hospitalization for observation without a medical AE; 
x 
Preplanned treatments or surgical procedures.  These should be noted in the baseline 
documentation for the entire protocol and/or for the individual patient; and, 
x 
Admission exclusively for the administration of blood products. 
Diagnostic and therapeutic noninvasive and invasive procedures, such as surgery, should not be 
reported as SAEs. However, the medical condition for which the procedure was performed should be 
reported if it meets the definition of an SAE. For example, an acute appendicitis that begins during the 
reporting period should be reported if the SAE requirements are met, and the resulting appendectomy 
should be recorded as treatment of the AE. 
8.3. 
Severity Assessment 
The intensity of AEs will be classified and recorded according to the NCI CTCAE (v4.03) in the CRF or 
according to the grading defined in section 5.4.1 if the AE is not specifically listed in NCI CTCAE. 
Note the distinction between the severity and the seriousness of an AE.  A severe event is not 
necessarily an SAE.  For example, a headache may be severe (interferes significantly with the patient’s 
usual function) but would not be classified as serious unless it met one of the criteria for SAEs, listed 
above. 
8.4. 
Special Situations 
8.4.1. 
Potential Cases of Drug-Induced Liver Injury 
Humans exposed to a drug who show no sign of liver injury (as determined by elevations in 
transaminases) are termed “tolerators,” while those who show transient liver injury, but adapt are 
CCI
090177e192741e05\Approved\Approved On: 16-Dec-2019 07:25 (GMT)

MDV3800-01/
 Protocol Version 2.0 Final 31-Aug-2018 
 
 
 
Page 68 
termed “adaptors.”  In some patients, transaminase elevations are a harbinger of a more serious 
potential outcome.  These patients fail to adapt and therefore are "susceptible" to progressive and 
serious liver injury, commonly referred to as drug-induced liver injury (DILI).  Patients who experience a 
transaminase elevation above 3 times the upper limit of normal (× ULN) should be monitored more 
frequently to determine if they are an “adaptor” or are “susceptible.” 
In the majority of DILI cases, elevations in aspartate aminotransferase (AST) and/or alanine 
aminotransferase (ALT) precede total bilirubin (TB) elevations (> 2 × ULN) by several days or weeks. The 
increase in TB typically occurs while AST/ALT is/are still elevated above 3 × ULN (ie, AST/ALT and TB 
values will be elevated within the same lab sample). In rare instances, by the time TB elevations are 
detected, AST/ALT values might have decreased. This occurrence is still regarded as a potential DILI. 
Therefore, abnormal elevations in either AST or ALT in addition to TB that meet the criteria outlined 
below are considered potential DILI (assessed per Hy’s law criteria) cases and should always be 
considered important medical events, even before all other possible causes of liver injury have been 
excluded. 
The threshold of laboratory abnormalities for a potential DILI case depends on the patient’s individual 
baseline values and underlying conditions. Patients who present with the following laboratory 
abnormalities should be evaluated further as potential DILI (Hy’s law) cases to definitively determine the 
etiology of the abnormal laboratory values: 
x 
Patients with AST/ALT and TB baseline values within the normal range who subsequently 
present with AST or ALT values > 3 × ULN and a TB value > 2 × ULN with no evidence of 
hemolysis and an alkaline phosphatase value < 2 × ULN or not available; 
x 
For patients with baseline AST or ALT or TB values above the ULN, the following threshold 
values are used in the definition mentioned above, as needed, depending on which values are 
above the ULN at baseline: 
o Pre-existing AST or ALT baseline values above the normal range: AST or ALT values > 
2 times the baseline values and > 3 × ULN; or > 8 × ULN (whichever is smaller). 
o Pre-existing values of TB above the normal range: TB level increased from baseline value 
by an amount of at least 1 × ULN or if the value reaches > 3 × ULN (whichever is smaller). 
Rises in AST/ALT and TB separated by more than a few weeks should be assessed individually based on 
clinical judgment; any case where uncertainty remains as to whether it represents a potential Hy’s law 
case should be reviewed with the sponsor.   
The patient should return to the investigator site and be evaluated as soon as possible, preferably within 
48 hfrom awareness of the abnormal results.  This evaluation should include laboratory tests, detailed 
history, and physical assessment.   
In addition to repeating measurements of AST, ALT and TB, laboratory tests should include albumin, 
creatine kinase (CK), direct and indirect bilirubin, gamma-glutamyl transferase (GGT), prothrombin time 
(PT)/international normalized ratio (INR), total bile acids, alkaline phosphatase and acetaminophen drug 
and/or protein adduct levels. Consideration should also be given to drawing a separate tube of clotted 
blood and an anticoagulated tube of blood for further testing, as needed, for further contemporaneous

analyses at the time of the recognized initial abnormalities to determine etiology. A detailed history, 
including relevant information, such as review of ethanol, acetaminophen (either by itself or as a 
coformulated product in prescription or over-the-counter medications), recreational drug, supplement 
(herbal) use and consumption, family history, sexual history, travel history, history of contact with a 
jaundiced person, surgery, blood transfusion, history of liver or allergic disease, and potential 
occupational exposure to chemicals, should be collected.  Further testing for acute hepatitis A, B, C, D, 
and E infection and liver imaging (e.g., biliary tract) may be warranted.  
All cases demonstrated on repeat testing as meeting the laboratory criteria of AST/ALT and TB elevation 
defined above should be considered potential DILI (Hy’s law) cases if no other reason for the LFT 
abnormalities has yet been found. Such potential DILI (Hy’s law) cases are to be reported as SAEs, 
irrespective of availability of all the results of the investigations performed to determine etiology of 
the LFT abnormalities.  
A potential DILI (Hy’s law) case becomes a confirmed case only after all results of reasonable 
investigations have been received and have excluded an alternative etiology. 
8.4.2. 
Exposure to the Investigational Product During Pregnancy or Breastfeeding, and 
Occupational Exposure 
Exposure to the investigational product under study during pregnancy or breastfeeding and 
occupational exposure are reportable to Pfizer Safety within 24 h of investigator awareness. 
8.4.2.1. 
Exposure During Pregnancy 
For both unapproved/unlicensed products and for marketed products, an exposure during pregnancy 
(EDP) occurs if: 
x 
A female becomes, or is found to be, pregnant either while receiving or having been exposed 
(eg, because of treatment or environmental exposure) to the investigational product; or the 
female becomes or is found to be pregnant after discontinuing and/or being exposed to the 
investigational product; 
x 
An example of environmental exposure would be a case involving direct contact with a Pfizer 
product in a pregnant woman (e.g., a nurse reports that she is pregnant and has been exposed 
to chemotherapeutic products). 
x 
A male has been exposed (e.g., because of treatment or environmental exposure) to the 
investigational product prior to or around the time of conception and/or is exposed during his 
partner’s pregnancy. 
If a patient or patient’s partner becomes or is found to be pregnant during the patient’s treatment with 
the investigational product, the investigator must report this information to Pfizer Safety on the SAE 
Report Form and an EDP supplemental form, regardless of whether an SAE has occurred. In addition, the 
investigator must submit information regarding environmental exposure to a Pfizer product in a 
pregnant woman (e.g., a patient reports that she is pregnant and has been exposed to a cytotoxic 
product by inhalation or spillage) to Pfizer Safety using the EDP supplemental form. This must be done 
irrespective of whether an AE has occurred and within 24 hof awareness of the exposure.  The

information submitted should include the anticipated date of delivery (see below for information 
related to termination of pregnancy). 
Follow-up is conducted to obtain general information on the pregnancy and its outcome for all EDP 
reports with an unknown outcome.  The investigator will follow the pregnancy until completion (or until 
pregnancy termination) and notify Pfizer Safety of the outcome as a follow-up to the initial EDP 
supplemental form.  In the case of a live birth, the structural integrity of the neonate can be assessed at 
the time of birth. In the event of a termination, the reason(s) for termination should be specified and, if 
clinically possible, the structural integrity of the terminated fetus should be assessed by gross visual 
inspection (unless pre-procedure test findings are conclusive for a congenital anomaly and the findings 
are reported). 
If the outcome of the pregnancy meets the criteria for an SAE (ie, ectopic pregnancy, spontaneous 
abortion, intrauterine fetal demise, neonatal death, or congenital anomaly [in a live-born baby, a 
terminated fetus, an intrauterine fetal demise, or a neonatal death]), the investigator should follow the 
procedures for reporting SAEs. 
Additional information about pregnancy outcomes that are reported to Pfizer Safety as SAEs follows:  
x 
Spontaneous abortion includes miscarriage and missed abortion; 
x 
Neonatal deaths that occur within 1 month of birth should be reported, without regard to 
causality, as SAEs. In addition, infant deaths after 1 month should be reported as SAEs when 
the investigator assesses the infant death as related or possibly related to exposure to the 
investigational product.  
Additional information regarding the EDP may be requested by the sponsor. Further follow-up of birth 
outcomes will be handled on a case-by-case basis (eg, follow-up on preterm infants to identify 
developmental delays). In the case of paternal exposure, the investigator will provide the patient with 
the Pregnant Partner Release of Information Form to deliver to his partner.  The investigator must 
document in the source documents that the patient was given the Pregnant Partner Release of 
Information Form to provide to his partner. 
8.4.2.2. 
Exposure During Breastfeeding 
Scenarios of exposure during breastfeeding must be reported, irrespective of the presence of an 
associated SAE, to Pfizer Safety within 24 h of the investigator’s awareness, using the SAE Report Form. 
An exposure during breastfeeding report is not created when a Pfizer drug specifically approved for use 
in breastfeeding women (e.g., vitamins) is administered in accord with authorized use. However, if the 
infant experiences an SAE associated with such a drug’s administration, the SAE is reported together 
with the exposure during breastfeeding. 
8.4.2.3. 
Occupational Exposure 
An occupational exposure occurs when, during the performance of job duties, a person (whether a 
healthcare professional or otherwise) gets in unplanned direct contact with the product, which may or 
may not lead to the occurrence of an AE.

An occupational exposure is reported to Pfizer Safety within 24 hours of the investigator’s awareness, 
using the SAE Report Form, regardless of whether there is an associated SAE. Since the information does 
not pertain to a patient enrolled in the study, the information is not recorded on a CRF; however, a copy 
of the completed SAE Report Form is maintained in the investigator site file. 
8.4.3. 
Medication Errors  
Other exposures to the investigational product under study may occur in clinical trial settings, such as 
medication errors.

Medication error 
All (regardless of whether associated 
with an AE) 
Only if associated with an 
SAE 
 
Medication errors may result from the administration or consumption of the investigational product by 
the wrong patient, or at the wrong time, or at the wrong dosage strength. 
Medication errors include: 
x 
Medication errors involving patient exposure to the investigational product; 
x 
Potential medication errors or uses outside of what is foreseen in the protocol that do or do 
not involve the participating patient. 
Such medication errors occurring to a study participant are to be captured on the medication error page 
of the CRF, which is a specific version of the AE page. 
In the event of medication dosing error, the sponsor should be notified immediately. 
Whether or not the medication error is accompanied by an AE, as determined by the investigator, the 
medication error is recorded on the medication error page of the CRF and, if applicable, any associated 
AE(s), serious and non-serious, are recorded on an AE page of the CRF.   
Medication errors should be reported to Pfizer Safety within 24 hours on a SAE Report Form only 
when associated with an SAE. 
There is no specific treatment in the event of talazoparib overdose, and symptoms of overdose are not 
established. In the event of overdose, treatment with talazoparib should be stopped, and physicians 
should consider gastric decontamination, follow general supportive measures and treat 
symptomatically.

9.1. 
Populations for Analyses 
All safety analyses will be performed using the safety population defined as all patients who received 
any amount of talazoparib. 
The PK concentration population is defined as all eligible patients enrolled and treated who have at least 
1 plasma talazoparib concentration. 
The PK parameter analysis population is defined as all evaluable patients enrolled and treated who have 
at least 1 of the talazoparib PK parameters of primary interest. 
9.2. 
Demographics and Screening Characteristics 
Demographics and screening characteristics data will be listed and summarized by each group. 
9.3. 
Protocol Treatment 
Duration of treatment, duration of exposure, cumulative dose and relative dose intensity will be 
summarized by renal impairment group using the safety population.  
9.4. 
Safety Endpoints 
The assessment of safety will be made on the safety population and will be based on summaries of AEs, 
physical examinations (including weight), vital signs, electrocardiograms (ECGs), laboratory evaluations 
and ECOG performance status.  
The latest version of the Medical Dictionary for Regulatory Activities (MedDRA) will be used to code all 
AEs to a preferred term and system organ class. 
The number and percentage of patients with adverse events will be presented by MedDRA’s System 
Organ Class (SOC) and Preferred Term (PT), relationship to study treatment, severity, seriousness and 
action taken (e.g., leading to permanent treatment discontinuation).  
Detailed listings for all AEs will also be provided. 
Laboratory parameters, graded according to the NCI CTCAE v4.03, will be summarized at screening, 
along visits and at the safety follow up visit. Tables of shifts in toxicity will also be provided. 
9.5. 
Pharmacokinetics Endpoints 
Actual PK sampling times and doses will be used for PK parameters calculations. 
The following PK parameters will be calculated by non-compartmental analysis using WinNonlin or 
another appropriate software.

Ae%: Percentage of dose excreted in urine as unchanged drug  
x 
CLr: renal clearance  
Additional PK parameters will be calculated as applicable.  
The concentration-times data of talazoparib 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 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 time will only be reported if the mean ш LLOQ; for mean < 
LLOQ, “missing” is reported in the tables.  
The PK characteristics of Tmax and Rac will be described utilizing minimum, maximum and median. All PK 
parameters except Tmax  and Rac will be expressed as individual data as well as arithmetic mean, standard 
deviation and coefficient of variation (CV), geometric mean, geometric CV, minimum, median, maximum 
value and the number of measurements. 
PK parameters AUC0-24, Cmax, Cmax,u, and AUC0-24,u on Days 1 and 22 will be natural log-transformed and 
analyzed using an analysis of variance (ANOVA) model with group as a fixed effect to compare each 
renal impairment group (mild, moderate or severe; Test) with the normal renal function group 
(Reference). Additionally, weight and age will be considered as covaraites (at the significance level of 
0.05). Estimates of the adjusted mean differences (Test - Reference) and corresponding 90% CIs for each 
comparison will be obtained from the model. The adjusted mean differences and the 90% CIs for the 
differences will be exponentiated to provide estimates of the ratio of adjusted geometric means 
(Test/Reference) and 90% CIs for the ratios on the untransformed scale.  
Relationship between renal functional measures (e.g. eGFR) and selected PK parameters may be 
explored graphically as appropriate. A regression line and 90% confidence region for the PK parameters 
and renal function will be included if appropriate. Vertical lines for the renal function group cut-off 
values will also be presented on the plots. Different symbols will be used to identify subjects from 
different renal function groups. 
Linear regression will be used to analyze the potential relationship between selected PK parameters and 
renal function.  Estimates of the slope and, intercept, together with their precision (90% CI), and the 
coefficient of determination will be obtained from the model. 
The PK parameters of talazoparib will be summarized descriptively by renal function group and Day.  
Boxplots of mean, median and individual subject parameters will be made across all the groups for 
AUC0-24, and Cmax by Day.  Concentrations will be listed and summarized descriptively by PK sampling 
time and group.  Summary profiles (means and medians) of the concentration- time data will be 
presented with all renal function groups plotted across different groups by Day. Individual subject 
concentration time profiles will be also presented.  For summary statistics and summary plots by 
sampling time, the nominal PK sampling time will be used, for individual subject plots by time, the actual 
PK sampling time will be used.

Sample Size  
Patients are assigned to one of four groups, based on renal function.  
The study will enroll at least 6 PK evaluable patients with advanced solid tumors per group so at least 24 
patients will be enrolled.  
If enrollment for severe renal impairment group is halted due to unacceptable toxicity profile, 2 
additional evaluable patients will be enrolled in each of Groups A, B and C (total of 8 PK evaluable 
patients each).  
Patients will be considered PK evaluable if they are eligible and have: 
x Completed 22 calendar days of treatment with talazoparib counted from day 1, regardless of any 
treatment hold and miss ч 5 consecutive doses of talazoparib, 
x Received at least 10 consecutive days of 0.5 mg talazoparib daily dose without dosing interruption 
prior to Day 22 PK sample collection, 
x Completed at least 85% of total plasma PK samples collection, 
x Not vomited talazoparib dose on Day 1 and Day 22 of the PK samples collection. 
 
Patients who discontinue the study before the completion of the Day 23 (i.e., 24 h of Day 22) 
assessment and/or who do not meet the above mentioned criteria may be replaced according to 
Sponsor´s judgment.

10. ADMINISTRATIVE, ETHICAL AND REGULATORY STANDARDS 
10.1. Study Committee 
No study committees are planned for this study.   
10.2. Ethical Conduct of the Study 
This clinical study was designed and shall be implemented and reported in accordance with the protocol, 
the ICH Harmonized Tripartite Guidelines for Good Clinical Practice, with applicable local regulations 
(including European Directives 2001/20/EC and 2005/28/EC and the US Code of Federal Regulations Title 
21), and with the ethical principles laid down in the Declaration of Helsinki. This study will be conducted 
under ethical, scientific and medical standards that protect the rights of participants which include 
informed consent, independent review, and post-study medical care.  
10.3. Institutional Review Board (IRB)  
Each participating institution must provide the review and approval of this protocol, the associated 
informed consent documents and any recruitment material to an appropriate Institutional Review Board 
(IRB). The IRB decision concerning the conduct of the study will be made in writing and kept with the 
Investigator study file. A copy of this decision will also be provided to 
 
Particular attention is drawn to the FDA's requirements for IRBs. By signing the "Statement of 
Investigator" form (Form FDA 1572), the Investigator provides 
 with the necessary assurance that 
an IRB is responsible for the initial/continuing review and subsequent approval of the proposed clinical 
study in accordance with these regulations when applicable. 
In compliance with the applicable country regulations, the Investigator is responsible for keeping the IRB 
informed of the progress with study renewal at least once a year, or more frequently, as required by the 
IRB. The Investigator must also report any SAE, life-threatening problems or deaths to the IRB as per 
institutional guidelines and inform the Sponsor according to GCP and applicable local regulations. The 
IRB must be informed by the Investigator of the termination of the study. 
10.4. Compliance with the Protocol and Protocol Amendments 
Investigators ascertain they will apply due diligence to avoid protocol deviations. Under no 
circumstances should the Investigator contact 
 or its agents, to request approval of a protocol 
deviation, as no such authorized deviations are permitted.  
When a deviation occurs in an emergency situation, such as when a departure from the protocol is 
required to protect the life or physical well-being of a participant, 
 and the reviewing IRB must be 
notified as soon as possible after the emergency situation occurred (ICH E6 GCP 4.5.2 and 21 CFR part 
312.66 ).  
A planned deviation from the protocol that is non-emergent and represents a major change in the 
protocol as approved by the IRB must be considered an amendment and treated as such. Even if the 
Investigator feels a protocol deviation would improve the conduct of the study this must be considered 
a protocol amendment, and unless such an amendment is agreed upon by 
/the Sponsor and 
subsequently approved by the Health Authorities and IRB, it cannot be implemented. All significant

protocol deviations will be recorded and reported in the Clinical Study Report (CSR). Any modifications 
to the protocol which may impact the conduct of the study, potential benefit of the patient or may 
affect patient safety, including changes of study objectives, study design, patient population, sample 
sizes, study procedures, or significant administrative aspects will require a formal amendment to the 
protocol.  As previously stated, only amendments that are required to eliminate an immediate hazard to 
patients for patient safety can be implemented prior to the IRB approval. Notwithstanding the need for 
approval of formal protocol amendments, the Investigator is expected to take any immediate action 
required for the safety of any patient included in this study, even if this action represents a deviation 
from the protocol. 
10.5. Monitoring, Auditing and Inspecting 
To ensure compliance with current local regulations and the ICH guidelines, data generated by this study 
must be available for monitoring, audit or inspection upon request by representatives of the national 
and local health authorities, 
/the Sponsor and duly authorized representatives of any entity 
providing support for this study. On site, they will notably review for AEs and study records and directly 
compare them with source documents, review regulatory documents, discuss the conduct of the study 
with the Investigator, verify study drug accountability and confirm that the facilities remain acceptable. 
10.6. Recording, Processing and Retention of Data 
The investigator is responsible for the preparation and maintenance of adequate case histories designed 
to record all observations and other relevant data. All patient data reported in the eCRF must be derived 
from source documents and as such be consistent with the source documents, or the discrepancies must 
be explained. 
Data will be entered and collected via an electronic data capture system (EDC) using eCRFs. EDC is a 
validated system designed for entry of data in compliance with U.S. Food and Drug Administration (FDA) 
regulations for electronic records (21 CFR Part 11). Study site staff will receive training and have access 
to a manual for appropriate eCRF completion. All eCRFs should be completed by designated, trained site 
staff. eCRFs should be reviewed and electronically signed and dated by the Investigator or authorized 
designee. Only identified and trained users may view the data as their actions will become part of the 
audit trail. 
While study sites will be responsible for data entry, 
 will be responsible for data management of 
this study, including quality checks. 
The eCRF must be completed shortly after the patient’s visit. All requested information must be entered 
on the eCRF. If an item is not available or is not applicable, it must be documented as such. The 
completed eCRF must be promptly reviewed and approved by the Investigator or authorized designee. 
In the event of discrepant data, 
 will request data clarification from the sites. The sites will resolve 
the discrepancy electronically in the EDC system. eCRF and data clarification documentation will be 
maintained in the EDC system’s audit trail. 
At the end of the study, the investigator will receive patient data, for their site, in a readable format on 
CD, DVD, or other similar storage format that must be kept with the study records. Acknowledgement of 
receipt of the storage disc or similar storage format is required.
