First seen Feb 28, 2026 · Last updated May 13, 2026 · Updated 6 times
Summary
This study tested whether adding an immunotherapy drug (pembrolizumab) to standard hormone therapy (letrozole) and a targeted drug (palbociclib) could shrink tumors in postmenopausal women with newly diagnosed stage IV estrogen receptor-positive breast cancer. The 47 participants received the combination to see how many had a partial or complete response. The goal is to improve treatment options for advanced breast cancer that has spread.
