Study Summary
This trial will assess if pembrolizumab, when combined with chemotherapy, is more effective in treating hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer than chemotherapy alone. The primary hypotheses are that the combination of pembrolizumab and chemotherapy is superior to placebo and chemotherapy in regards to Progression-Free Survival (PFS) or overall survival (OS) in participants with programmed cell death-ligand 1 (PD-L1) combined positive score (CPS) ≥1 and ≥10.
Who is the study for?
This trial is for adults with HR+/HER2- breast cancer that's locally recurrent and inoperable or has spread (metastatic), who haven't had chemotherapy for this condition before, but have progressed after endocrine therapy. They should be candidates for chemotherapy, have a certain level of PD-L1 protein on their tumor cells, good organ function, measurable disease per RECIST 1.1 criteria, and an ECOG performance status of 0 or 1.Check my eligibility
What is being tested?
The study tests if pembrolizumab combined with the investigator's choice of chemotherapy improves survival without cancer progression compared to placebo plus chemotherapy in patients whose tumors express PD-L1. The effectiveness will be measured by how long patients live without their disease getting worse (PFS) and overall survival (OS).See study design
What are the potential side effects?
Possible side effects include reactions related to immune system activation such as inflammation in various organs including lungs (pneumonitis), infusion-related reactions from the drug entering the body, fatigue, skin issues like rash or itching, digestive problems like diarrhea or nausea, liver function changes and potential risk of infections.
