ClinConnect Summary
The ASCENT-05 clinical trial is studying a new treatment approach for patients with triple negative breast cancer (TNBC) who still have cancer remaining after surgery and previous therapy. This trial is comparing an experimental treatment that combines sacituzumab govitecan-hziy (SG) with pembrolizumab to the standard treatment options, which may include pembrolizumab alone or pembrolizumab with another medication called capecitabine. The goal is to find out if this new combination is more effective and safe for patients.
To participate in this trial, patients must be over 18 years old and have residual invasive TNBC in the breast or lymph nodes after receiving surgery and pre-surgical treatment. They should have had their cancer surgically removed, recovered from that surgery, and undergone appropriate radiotherapy. Importantly, patients with more advanced stages of cancer or certain health conditions may not be eligible. Participants can expect to receive close monitoring and support throughout the study, contributing valuable information to help improve future treatments for TNBC.
