A Randomized, Open-label, Phase 3 Study of Adjuvant Sacituzumab Govitecan and Pembrolizumab Versus Treatment of Physician s Choice in Patients With Triple Negative Breast Cancer Who Have Residual Invasive Disease After Surgery and Neoadjuvant Therapy (ASCENT-05)
The purpose of this study is to see if sacituzumab govitecan in combination with pembrolizumab can improve outcomes and delay the return of disease in participants with high-risk early Triple Negative Breast Cancer (TNBC) when compared to pembrolizumab alone or pembrolizumab in combination with capecitabine. Participants with low tumor expression of the estrogen and/or progesterone receptors (1 to 10%) will also be included in this study. The study treatment will be chosen by chance—like flipping a coin. There is a 1 out of 2 chances to receive Sacituzumab govitecan in combination with Pembrolizumab and 1 out of 2 chances to receive a study treatment of study doctor’s choice of either pembrolizumab alone or pembrolizumab in combination with capecitabine. Participants and their study doctor will know what study drug is being taken.
• invasive triple negative breast cancer (TNBC) still remains in the breast or lymph nodes after therapy and surgery
• unable to do physically strenuous activity but able to walk and carry out work of a light or sedentary nature, e.g., light house work, office work
• see link to clinicaltrials.gov for complete inclusion and exclusion criteria
• Stage IV (metastatic) breast cancer or previous cancer in the same or other breast
• evidence that the cancer has reoccurred after preoperative therapy and surgery
• presence of germline breast cancer gene (BRCA) mutations
