Study Summary
This trial is comparing the efficacy of two different treatments for triple negative breast cancer - olaparib plus pembrolizumab versus chemotherapy plus pembrolizumab. The primary hypotheses are that olaparib plus pembrolizumab will be superior to chemotherapy plus pembrolizumab in terms of progression-free survival and overall survival.
Who is the study for?
This trial is for adults with triple negative breast cancer (TNBC) that's either inoperable and not previously treated with chemotherapy, or metastatic without prior chemo. Participants should have a life expectancy of at least 27 weeks, be in good physical condition (ECOG status of 0 or 1), have adequate organ function, and agree to use contraception. Pregnant or breastfeeding women, those with certain other cancers or conditions like active CNS metastases, autoimmune diseases requiring recent treatment, severe infections including HIV/Hepatitis B/C, heart failure within the past six months, uncontrolled illnesses that could affect study participation are excluded.Check my eligibility
What is being tested?
The study compares two treatments after initial chemo plus pembrolizumab: one group will receive olaparib plus pembrolizumab while the other continues on standard chemotherapy plus pembrolizumab. The goal is to see which combination is better at stopping cancer progression (PFS) and improving survival rates (OS). Enrollment has stopped but ongoing participants can continue if benefiting.See study design
What are the potential side effects?
Possible side effects include allergic reactions to medication components; issues from immune system activation such as inflammation in organs; blood disorders; fatigue; digestive problems; increased risk of infection due to weakened immunity. Specifics depend on individual responses and may vary.

Experimental Treatment
Group I: Pembrolizumab + OlaparibExperimental Treatment2 Interventions
This arm includes participants who randomized following completion of the induction period. After the induction period, participants received pembrolizumab 200 mg intravenously on Day 1 of each 21-day cycle plus olaparib 300 mg orally twice daily during the post-induction period.
Group II: Pembrolizumab + Carboplatin + GemcitabineExperimental Treatment3 Interventions
This arm includes participants who randomized following completion of the induction period. Participants continued to receive both carboplatin AUC 2 with gemcitabine 1000 mg/m^2 intravenously on Days 1 and 8 of each 21-day cycle in addition to pembrolizumab 200 mg intravenously on Day 1 of each 21-day cycle in the post-induction period.
