Approval of Accord’s Trastuzumab Biosimilar: On September 18, 2024, Accord announced that the Food and Drug Administration (FDA) approved a 420 mg dosage of HERCESSI (trastuzumab-strf), a biosimilar to Genentech’s HERCEPTIN (trastuzumab), to treat HER2-overexpressing breast and gastric or gastroesophageal junction adenocarcinoma. As we previously reported, HERCESSI was approved earlier this year by the FDA at a dosage of 150 mg. According to Binish Chudgar, vice chairman and managing director of Intas Pharmaceuticals (of which Accord is a specialty subdivision), “[t]he FDA’s approval of both strengths of HERCESSI marks the beginning of Accord BioPharma’s journey to bring a portfolio of biosimilars to the U.S. that can help achieve significant savings.”
