Lancet Oncology. In the DESTINY-Breast01 trial, trastuzumab deruxtecan demonstrated clinically meaningful and durable activity in patients who had received two or more prior anti-HER2 therapies. The safety and tolerability profile of trastuzumab deruxtecan seen in DESTINY-Breast01 was consistent with that observed in the phase 1 trial.
An updated analysis from DESTINY-Breast01, reinforcing the durable efficacy and long-term safety and tolerability profile of trastuzumab deruxtecan, was presented earlier this week at the 2020 San Antonio Breast Cancer Symposium (SABCS).
“We are encouraged by the CHMP positive opinion given the significant unmet need for patients with HER2 positive metastatic breast cancer,” said Gilles Gallant, BPharm, PhD, FOPQ, Senior Vice President, Global Head, Oncology Development, Oncology R&D, Daiichi Sankyo. “Trastuzumab deruxtecan is already available for patients with HER2 positive metastatic breast cancer in the U.S. and Japan, and we are now one step closer to bringing this important new medicine to patients in Europe.”
