Are Oral SERDs About to Transform Breast Cancer Care?

The development of oral selective estrogen receptor degraders (SERDs) represents substantial progress for patients with metastatic breast cancer who have ESR1 mutations. “I’m extremely excited because they’re the most effective form of endocrine therapy today,” says Wassim Mchayleh, MD, MBA, the clinical program director of the breast cancer program at AdventHealth Cancer Institute and associate professor of medicine at the University of Central Florida in Orlando. He spoke with Robert A. Figlin, MD, the interim director of Cedars-Sinai Cancer in Los Angeles and Steven Spielberg Family Chair in Hematology-Oncology about SERDs that are currently available and those in development. When it comes to weighing toxicity, “across the board, they are very well-tolerated endocrine therapies with a very low discontinuation rate,” Dr. Mchayleh noted. In addition to recent key clinical trial results, he also looked ahead to what data may help establish the drug class as a replacement for the current standard of care.
