ClinConnect Summary

This clinical trial is investigating how well a combination of three different treatments works for patients with stage IV or unresectable recurrent triple-negative breast cancer. The study focuses on using a drug called avelumab, which boosts the immune system, along with either liposomal doxorubicin (a chemotherapy drug in tiny fat particles that may cause fewer side effects) or sacituzumab govitecan (a targeted therapy that delivers a chemotherapy drug directly to cancer cells). The trial aims to see if these combinations can help improve treatment outcomes for patients whose cancer is hard to treat.

To be eligible for this trial, participants need to be at least 18 years old and have a specific type of breast cancer that is not hormone receptor positive or HER2 positive. They should also have measurable cancer that can be monitored during the study. Participants can expect to undergo a two-week period of treatment to prepare their immune systems, followed by the combination therapies. It’s important to note that participants will need to follow certain health guidelines, such as having a stable overall health status and not currently being on other cancer treatments. This trial is actively recruiting participants, and it offers a chance to contribute to important research that could help others facing similar challenges.

Post-menopausal status in females under 55 years of age should be confirmed with a serum follicle-stimulating hormone (FSH) level within laboratory reference range for postmenopausal women

Re-enrollment of a subject that has discontinued the study as a pre-randomization screen failure (i.e., a consented patient who was not randomized and did not receive any study treatment) is permitted. If re-enrolled, the subject must be re-consented. Only the screening procedures performed outside of protocol-specified timing must be repeated; if biopsies and correlative blood samples were already obtained, and patient has not received any systemic anti-cancer therapy since they were obtained, they do not need to be repeated.
