Trodelvy® Significantly Improves Overall Survival in Pre-Treated HR+/HER2- Metastatic Breast Cancer Patients in the TROPiCS-02 Study
–Trodelvy is the First TROP-2 Directed ADC to Show a Significant Improvement in Overall Survival in HR+/HER2- Breast Cancer –
– Planned SecondInterim Analysis Demonstrated a Statistically Significant and Clinically Meaningful Benefit for Overall Survival –
FOSTER CITY, Calif.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) today announced statistically significant and clinically meaningful results from the second interim analysis of the key secondary endpoint of overall survival (OS) in the Phase 3 TROPiCS-02 study evaluating Trodelvy® (sacituzumab govitecan-hziy) in patients with HR+/HER2- metastatic breast cancer who received prior endocrine therapy, CDK4/6 inhibitors and two to four lines of chemotherapy. Detailed OS results will be presented at an upcoming medical conference. The safety profile for Trodelvy was consistent with prior studies, and no new safety signals emerged in this patient population.
“These survival results from the TROPiCS-02 study are important for the breast cancer community and we are encouraged by the potential this may have in helping patients who otherwise have limited alternatives,” said Merdad Parsey, MD, PhD, Chief Medical Officer, Gilead Sciences. “We look forward to discussing these results with global health authorities, as pre-treated HR+/HER2- metastatic disease patients currently have limited treatment options and poor quality of life.”
Gilead has submitted a supplemental Biologics License Application (sBLA) to the U.S. Food & Drug Administration (FDA). These data will also be shared with health authorities outside the U.S.
In June 2022, based on the positive primary results from the TROPiCS-02 study presented at the 2022 American Society of Clinical Oncology (ASCO) Annual Meeting, the National Comprehensive Cancer Network® (NCCN®) Clinical Practice Guidelines in Oncology (NCCN Guidelines®)i included a category 2A preferred recommendation for sacituzumab govitecan-hziy for the investigational use in patients with HR+/HER2- advanced breast cancer after prior treatment including endocrine therapy, a CDK4/6 inhibitor and at least two lines of chemotherapy. The TROPiCS-02 study enrolled HR+/HER2- metastatic breast cancer patients, which included patients with HER2-low and IHC 0 status.
TROPiCS-02 is an event driven study with planned analyses based on a pre-specified number of events. This interim analysis was executed based on the pre-specified criteria.
Trodelvy has not been approved by any regulatory agency for the treatment of HR+/HER2- metastatic breast cancer. Its safety and efficacy have not been established for this indication. Trodelvy has a Boxed Warning for severe or life-threatening neutropenia and severe diarrhea; please see below for additional Important Safety Information.
