FDA Accepts Biologics License Application for New Metastatic HER2+ Breast Cancer Treatment


The FDA accepted the supplemental Biologics License Application of trastuzumab deruxtecan for the treatment of unresectable or metastatic HER2-positive breast cancer in patients who have received a prior anti-HER2-based regimen.  

Trastuzumab deruxtecan is a HER2-directed antibody drug conjugate in development by AstraZeneca and Daiichi Sankyo. 

The application is under review via the Real-Time Oncology Review program, which allows the FDA to review components of the application before the complete submission. It is also under review via Project Orbis, which allows for concurrent submission and review of oncology medicines among participating international partners. 

In the DESTINY-Breast03 trial presented during the European Society for Medical Oncology (ESMO) Congress 2021, patients previously treated with trastuzumab and a taxane, trastuzumab deruxtecan demonstrated a 72% reduction in the risk of disease progression or death compared to T-DM1 (HR 0.28; 95% CI: 0.22-0.37; P =7.8x10-22).  

Approximately 94.1% of patients treated with trastuzumab deruxtecan were alive at one year, compared to 85.9% of patients treated with T-DM1. The confirmed objective response rate (ORR) was more than doubled compared to T-DM1 (79.7% vs. 34.2%).  

“This regulatory review of [trastuzumab deruxtecan] in the US marks the first time this medicine is participating in both the Real-Time Oncology Review and Project Orbis programs. The FDA’s prioritization of our application underscores the potential of this medicine and the continued need to expedite the availability of new treatment options, while making it possible to potentially receive approvals in several countries concurrently,” Ken Takeshita, Global Head, R&D, Daiichi Sankyo, said in the press release.
