Tirzepatide for weight loss in MRD-positive early breast cancer
This study tests whether the weight-loss drug tirzepatide (Mounjaro) can help prevent breast cancer from coming back in people who are overweight and have a sign of leftover cancer cells in their blood (called MRD-positive). You must have already finished at least one year of hormone therapy for early-stage breast cancer.

Testing two antibody drugs for HER2-low breast cancer
This trial tests two antibody-drug conjugates (Enhertu and Datroway) for breast cancer that is HER2-low or HER2-0. It aims to find the best treatment sequence for people whose cancer has stopped responding to prior therapy.
Birmingham, AlabamaAges 18 years+ - NCT06545682RecruitingPhase 1
Study of alpelisib and pembrolizumab for advanced breast cancer or melanoma
This trial tests a combination of two drugs, alpelisib and pembrolizumab, for people with advanced triple-negative breast cancer or melanoma that has spread. The goal is to see if the combination can help shrink tumors, including those that have spread to the brain.
