FDA Approves Enhertu for Some Additional Breast Cancers

Share

FDA has approved Daiichi Sankyo’s Enhertu (fam-tastuzumab deruxtecan-nxki) for adult patients with unresectable or metastatic HER2-positive breast cancer who have received a prior anti-HER2-based regimen either in the metastatic setting or in the neoadjuvant setting and have developed disease recurrence during or within six months of completing therapy. An agency announcement says Enhertu received 12/2019 accelerated approval for adult patients with unresectable or metastatic HER2-positive breast cancer who have received two or more prior anti-HER2-based regimens in the metastatic setting. The following study was the confirmatory trial for the accelerated approval.

Efficacy for the new indication was based on DESTINY-Breast03, FDA says. The main efficacy outcome was progression-free survival, while overall survival and confirmed objective response rate were the key secondary outcome measures.

The labeling includes a Boxed Warning on the risk of interstitial lung disease and embryo-fetal toxicity.

FDA’s review was conducted under Project Orbis, an initiative of the FDA Oncology Center of Excellence. For this review the agency collaborated with the Australian Health Goods Administration, Health Canada, Israel’s Ministry of Health Pharmaceutical Administration, and Switzerland’s Swissmedic.

The review used the Real-Time Oncology Review pilot program to streamline data submission before filing the entire clinical application, and the Assessment Aid voluntary submission. The application was granted FDA priority review, breakthrough designation, and orphan drug designation.
