EMA validates marketing authorization application for Trodelvy for Pre-treated HR+/HER2- Metastatic Breast Cancer: Gilead Sciences

“At Gilead Oncology our ambition is to transform care for people with cancer,” said Bill Grossman, MD, PhD, Senior Vice President, Therapeutic Area Head, Gilead Oncology. “Trodelvy is already moving us towards this ambition and changing the standard of care in second-line metastatic triple-negative breast cancer across the EU. The validation of our Marketing Authorization Application in pre-treated HR+/HER2- metastatic breast cancer marks an important step forward to potentially making Trodelvy available to even more patients with severely limited treatment options.”

Trodelvy (sacituzumab govitecan-hziy) is a first-in-class Trop-2 directed antibody-drug conjugate. Trop-2 is a cell surface antigen highly expressed in multiple tumor types, including in more than 90% of breast and bladder cancers. 

This Marketing Authorization Application is based on data from the registrational Phase 3 TROPiCS-02 study, which met its primary endpoint of progression-free survival (PFS) and key secondary endpoint of overall survival (OS) versus comparator chemotherapies (treatment of physician’s choice (TPC) of chemotherapy). PFS data were published in the Journal of Clinical Oncology, and OS data were recently presented at ESMO Congress 2022.

The safety profile for Trodelvy in TROPiCS-02 was consistent with prior studies, and no new safety signals were identified in this population.

In October 2022, the U.S. Food and Drug Administration (USFDA) accepted for priority review the supplemental Biologics License Application (sBLA) for Trodelvy for the treatment of adult patients with unresectable locally advanced or metastatic HR+/HER2-negative (IHC 0, IHC 1+ or IHC 2+/ISH–) breast cancer who have received endocrine-based therapy and at least two additional systemic therapies in the metastatic setting. The Prescription Drug User Fee Act (PDUFA) target action date is currently set for February 2023.
