Summary

This trial is testing whether sacituzumab govitecan or pembrolizumab are safe and effective for treating triple negative breast cancer that has spread to other parts of the body and is PD-L1-negative.

Who is the study for?
This trial is for adults with PD-L1-negative metastatic triple-negative breast cancer (TNBC). Participants must have not received treatment for metastasis, be in good physical condition, and have normal organ/marrow function. They should agree to a research biopsy if possible. Pregnant women or those breastfeeding are excluded, as well as anyone with certain medical conditions or recent treatments that could interfere with the study.
What is being tested?
The trial tests Sacituzumab Govitecan (Trodelvy) alone or combined with Pembrolizumab (Keytruda) in patients whose TNBC has spread and doesn't respond to PD-L1 targeting therapies. It aims to determine the safety and effectiveness of these drugs in managing advanced TNBC.
What are the potential side effects?
Possible side effects include allergic reactions to medication components, immune system complications like inflammation of organs, fatigue, digestive issues such as diarrhea from irinotecan-related risks especially in individuals with UGT1A1*28 allele homozygosity, blood disorders including neutropenia which is a low white blood cell count.

Trial Design

3Treatment groups
Experimental Treatment
Group I: Sacituzumab Govitecan + PembrolizumabExperimental Treatment2 Interventions
Participants will receive Sacituzumab Govitecan + Pembrolizumab at a pre-determined dose during a 21 day cycle. Sacituzumab Govitecan will be given on days 1 and 8 of the 21 day cycle Pembrolizumab will be given on day 1 of the 21 day cycle.
Group II: Sacituzumab GovitecanExperimental Treatment1 Intervention
Participants will receive Sacituzumab Govitecan at a pre-determined dose during a 21 day cycle. Sacituzumab Govitecan will be given on days 1 and 8 of a 21-day cycle
Group III: RetreatmentExperimental Treatment2 Interventions
Participants randomized to the combination arm (Sacituzumab Govitecan + Pembrolizumab) who stop with CR after at least 24 weeks of treatment may be eligible for additional pembrolizumab and/or sacituzumab govitecan therapy if they progress after stopping study treatment. This is termed the Second Course Phase and is only available if the study remains open and the subject meets conditions. .
