CHICAGO – The addition of pembrolizumab to standard chemotherapy improved the pathologic complete response rate among women with HER-2–negative breast cancer, according to results of the I-SPY 2 trial presented at the ASCO Annual Meeting.
Douglas Yee, MD, director of the Masonic Cancer Center, professor of medicine and pharmacology at University of Minnesota, and HemOnc Today Editorial Board member, describes the trial design and the impact of the results.
“All the HER-2–negative subgroups benefited from the addition of pembrolizumab,” including patients with hormone-receptor–positive and hormone-receptor–negative disease, Yee told HemOnc Today. “To the best of our knowledge, this is the first demonstration that you can add an agent to conventional cytotoxic chemotherapy in the hormone-receptor–positive subgroup and improve responses. That was very exciting.”
