- Received an antineoplastic therapy or investigational agent after treatment with talazoparib in the originating protocol.
- Has a clinically significant cardiovascular, dermatologic, endocrine, gastrointestinal, hematologic, infectious, metabolic, neurologic, psychologic, or pulmonary disorder or any other condition, including excessive alcohol or drug abuse, or secondary malignancy, that may interfere with study participation in the opinion of the investigator.
- Diagnosis of myelodysplastic syndrome (MDS).

- Primary Outcome Measures
Name Time Method Number of Participants With NCI-CTCAE Grade 3/4 Postbaseline Laboratory Toxicities: Hematology Parameters From start of study treatment up to 30 days after last dose of study treatment or before initiation of a new antineoplastic therapy, whichever occurred first (approximately maximum for 4.6 years) The following hematology parameters were analyzed: hemoglobin, leukocytes, lymphocytes, neutrophils and platelets. Laboratory toxicities were graded using NCI-CTCAE version 4 where, grade 1 (mild), grade 2 (moderate), grade 3 (severe), grade 4 (potentially life threatening) and grade 5 (death) for each parameter. Number of participants with Grade 3 and 4 toxicities were reported. Low indicates values lower than the normal range.
Number of Participants With Treatment-Emergent Adverse Events (TEAEs), Treatment Emergent Serious Adverse Events (SAEs), Treatment Emergent Treatment Related AEs and Treatment Emergent Treatment Related SAEs From start of study treatment up to 30 days after last dose of study treatment or before initiation of a new antineoplastic therapy, whichever occurred first (approximately maximum for 4.6 years) An adverse event (AE) was any untoward medical occurrence in a participant administered a study drug without regard to possibility of a causal relationship. SAE was any untoward medical occurrence that at any dose resulted in death; inpatient hospitalization or prolongation of existing hospitalization; was life-threatening (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly/birth defect or was considered as an important medical event. TEAEs were AEs that occurred on or after the administration of first dose of study drug through approximately 30 days after the last dose. AE included both SAEs and all non-SAEs. Treatment-related TEAEs were defined as any TEAE with at least a possible relationship to the study drug as assessed by the investigator or that was missing the assessment of causal relationship whose relationship to the study drug could not be ruled out.
Number of Participants With Grade 3 or 4 TEAEs Based on National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) Version 4 From start of study treatment up to 30 days after last dose of study treatment or before initiation of a new antineoplastic therapy, whichever occurred first (approximately maximum for 4.6 years) An AE was any untoward medical occurrence in a participant administered a study drug without regard to possibility of a causal relationship. TEAEs were AEs that occurred on or after the administration of first dose of study drug through approximately 30 days after the last dose. Severity was graded using NCI-CTCAE version 4 where, Grade 1: mild AE; Grade 2: moderate AE; Grade 3: severe AE; Grade 4: life-threatening consequences, urgent intervention indicated; Grade 5: death related to AE. Number of participants with Grade 3 or 4 TEAEs were reported.
Number of Participants With Clinically Significant Laboratory Abnormalities: Liver Function Tests From start of study treatment up to 30 days after last dose of study treatment or before initiation of a new antineoplastic therapy, whichever occurred first (approximately maximum for 4.6 years) The following liver parameters were analyzed: aspartate transaminase (AST), alanine aminotransferase (ALT), total bilirubin (TBL) and alkaline phosphatase (ALP). The criteria for clinically significant abnormalities for liver parameters included AST or ALT greater than or equal to (\>=) 3 times upper limit of normal (ULN); ALT or AST greater than (\>) 5 times ULN; ALT or AST \> 10 times ULN; ALT or AST \> 20 times ULN; total TBL \>2 times ULN; ALT or AST \>= 3 times ULN and TBL \> 2 times ULN and ALT or AST \>= 3 times ULN and TBL \> 2 times ULN and ALP \< 2 times ULN.
Number of Participants With TEAEs Leading to Dose Reduction, Permanent Study Drug Discontinuation and Death From start of study treatment up to 30 days after last dose of study treatment or before initiation of a new antineoplastic therapy, whichever occurred first (approximately maximum for 4.6 years) An AE was any untoward medical occurrence in a participant administered a study drug without regard to possibility of a causal relationship. TEAEs were AEs that occurred on or after the administration of first dose of study drug through approximately 30 days after the last dose. Number of participants with TEAEs leading to dose reduction, permanent study drug discontinuation and death were reported.
Number of Participants With NCI-CTCAE Grade 3/4 Postbaseline Laboratory Toxicities: Chemistry Parameters From start of study treatment up to 30 days after last dose of study treatment or before initiation of a new antineoplastic therapy, whichever occurred first (approximately maximum for 4.6 years) The following chemistry parameters were analyzed: alkaline phosphatase, bilirubin and creatinine. Laboratory toxicities were graded using NCI-CTCAE version 4 where, grade 1 (mild), grade 2 (moderate), grade 3 (severe), grade 4 (potentially life threatening) and grade 5 (death) for each parameter. Number of participants with Grade 3 or 4 toxicities were reported. High indicates values higher than the normal range.
Number of Participants With Clinically Significant Changes in Vital Signs and Weight From start of study treatment up to 30 days after last dose of study treatment or before initiation of a new antineoplastic therapy, whichever occurred first (approximately maximum for 4.6 years) Criteria for clinically significant changes in vital signs included a) Systolic blood pressure (SBP): 1) absolute results \>180 millimeter of mercury (mmHg) and increase from baseline \>=40 mmHg, 2) absolute results \<90 mmHg and decrease from baseline \>30 mmHg; b) Diastolic blood pressure (DBP): 1) absolute results \>110 mmHg and increase from baseline \>=30 mmHg , 2) absolute results \<50 mmHg and decrease from baseline \>20 mmHg , 3) increase from baseline \>=20 mmHg; c) Heart rate: 1) absolute results \>120 beats per minute (bpm) and increase from baseline \>30 bpm, 2) absolute results \<50 bpm and \>20 bpm decrease from baseline; d) Temperature: \<=34.5 or \>=38 degree Celsius. Criteria for clinically significant changes in weight: \>10 percent (%) decrease from baseline.
