This phase II trial studies how well talazoparib works in treating patients with homologous recombination repair deficiency (HRRD) positive stage IV squamous cell lung cancer that has come back after previous treatment. Talazoparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
PRIMARY OBJECTIVES: I. To evaluate the overall response rate (ORR) (confirmed and unconfirmed, complete and partial) with talazoparib (BMN 673) in HRRD Medivation (MDVN)-positive patients. SECONDARY OBJECTIVES: I. To evaluate investigator assessed progression-free survival (IA-PFS) and overall survival (OS) associated with therapy in HRRD MDVN-positive patients. II. To evaluate ORR, IA-PFS, and OS in HRRD Foundation Medicine, Inc. (FMI)-positive patients. III. To evaluate ORR in HRRD MDVN-negative/HRRD FMI-positive patients. IV. To evaluate the frequency and severity of toxicities associated with talazoparib (BMN 673) in HRRD FMI-positive patients. TERTIARY OBJECTIVES: I. To assess if the homologous recombination deficiency (HRD) score is associated with clinical outcomes (response, PFS, OS) in HRRD FMI-positive patients treated with talazoparib (BMN 673). II. To assess if the level of PARP protein expression determined by immunohistochemistry is associated with clinical outcomes (response, PFS, OS) in HRRD FMI-positive patients treated with talazoparib (BMN 673). III. To characterize pharmacokinetic properties of talazoparib (BMN 673). OUTLINE: Patients receive talazoparib orally (PO) once daily (QD) on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 1 year, every 6 months for 2 years, and at the end of year 3.

Overall Response Rate Assessed by Response Evaluation Criteria in Solid Tumors 1.1 in HRRD-positive (MDVN) Participants
The percentage of participants with confirmed and unconfirmed, partial response and complete response to treatment with talazoparib per Response Evaluation Criteria in Solid Tumors Criteria (RECIST 1.1). Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by MRI or CT: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR Analysis was performed using a more restricted definition of homologous recombination repair deficiency (HRRD)-positivity (Medivation \[MDVN\] criteria; defined by alterations in ATM/ATR/BRCA1/BRCA2/PALB2 genes). With 40 HRRD subset positive patients, overall response rate can be estimated within 13% with 95% confidence.
Time frame: Up to 3 years post sub-study registration
Investigator-assessed Progression-free Survival (IA-PFS) in HRRD-positive (MDVN) Participants
From date of sub-study registration to date of first documentation of progression assessed by local review or symptomatic deterioration or death due to any cause. Participants last known to be alive without report of progression were censored at date of last disease assessment. Analysis was performed using a more restricted definition of homologous recombination repair deficiency (HRRD)-positivity (Medivation \[MDVN\] criteria; defined by alterations in ATM/ATR/BRCA1/BRCA2/PALB2 genes).
Time frame: Up to 3 years post sub-study registration
Overall Survival (OS) in HRRD-positive (MDVN) Participants
From date of sub-study registration to date of death due to any cause. Participants last known to be alive were censored at date of last contact. Analysis was performed using a more restricted definition of homologous recombination repair deficiency (HRRD)-positivity (Medivation \[MDVN\] criteria; defined by alterations in ATM/ATR/BRCA1/BRCA2/PALB2 genes).
Time frame: Up to 3 years post sub-study registration
Overall Response Rate Assessed by Response Evaluation Criteria in Solid Tumors 1.1 in HRRD-positive (FMI) Participants
The percentage of participants with confirmed and unconfirmed, partial response and complete response to treatment with talazoparib per Response Evaluation Criteria in Solid Tumors Criteria (RECIST 1.1). Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by MRI or CT: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR Analysis was performed using a broader definition of homologous recombination repair deficiency (HRRD)-positivity (Foundation Medicine Inc. \[FMI\] criteria; defined by alterations in ATM/ATR/BARD1/BRCA1/BRCA2/BRIP1/CHEK1/CHEK2/FANCA/FANCC/FANCD2/FANCF/FANCM/NBN(NBS1)/PALB2/RAD51/RAD51B(RAD51L1)/RAD54L/RPA1 genes).

Investigator-assessed Progression Free Survival (IA-PFS) FEP in HRRD-positive (FMI) Participants
From date of sub-study registration to date of first documentation of progression assessed by local review or symptomatic deterioration or death due to any cause. Participants last known to be alive without report of progression were censored at date of last disease assessment. Analysis was performed using a broader definition of homologous recombination repair deficiency (HRRD)-positivity (Foundation Medicine Inc. \[FMI\] criteria; defined by alterations in ATM/ATR/BARD1/BRCA1/BRCA2/BRIP1/CHEK1/CHEK2/FANCA/FANCC/FANCD2/FANCF/FANCM/NBN(NBS1)/PALB2/RAD51/RAD51B(RAD51L1)/RAD54L/RPA1 genes).
