Celltrion BLA for Herceptin Biosimilar
FDA has approved a Celltrion BLA for Herzuma (trastuzumab-pkrb) as a biosimilar to Genentech’s Herceptin (trastuzumab) for patients with HER2-overexpressing breast cancer. Common adverse events include headache, diarrhea, nausea, chills, fever, infection, congestive heart failure, insomnia, cough, and rash. Serious expected side effects of Herzuma include worsening of chemotherapy-induced neutropenia, an FDA release says. Like Herceptin, Herzuma’s labeling contains a Boxed Warning to alert health care professionals and patients about increased risks of cardiomyopathy, infusion reactions, pulmonary toxicity, and embryo-fetal toxicity.
