PFS is defined as the time from randomization to death or the first documented progression, whichever occurs first, confirmed by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria, as determined based on blinded independent central review (BICR)
Type, incidence, severity (as graded by National Cancer Institute \[NCI\] Common Terminology Criteria for Adverse Events \[CTCAE\] v5.0), seriousness, and relationship to study medications of adverse events (AEs) and any laboratory abnormalities
Incidence of dose-limiting toxicities (DLTs) and AEs graded according to NCI CTCAE v5.0
Radiographic progression-free survival rate at 6 months as measured by the Kaplan-Meier (K-M) method and assessed based on Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 with modifications as specified in Prostate Cancer Working Group 3 (PCWG3) criteria
Determine the recommended Phase 2 dose (RP2D) of talazoparib in combination with gedatolisib in patients with advanced human epidermal growth factor receptor 2 (HER2) negative (triple negative or BRCA1/2 deficient) breast cancer.
Calculate ORR, which will include confirmed complete response (CR) + confirmed partial response (PR) determined as per RECIST1.1 on treatment with talazoparib in combination with gedatolisib in patients with BRCA1/2 deficient advanced HER2 negative breast cancer.
Number of patients for each response category, objective response rate (number of patients with a complete response (CR)) relative to the number of response evaluable patients
