FDA accelerated approval of Ziihera (zanidatamab-hrii) 50mg/mL for injection for intravenous use for the treatment of adults with previously treated, unresectable or metastatic HER2-positive biliary tract cancer, as detected by an FDA-approved test. Ziihera was approved under accelerated approval based on a 52% objective response rate and a median duration of response of 14.9 months as determined by independent central review. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. The phase III HERIZON-BTC-302 confirmatory trial is ongoing to evaluate zanidatamab in combination with standard-of-care therapy versus standard-of-care therapy alone in the first-line setting for patients with HER2-positive BTC.
Rick Pazdur, MD, the newly appointed director for the Center for Drug Evaluation and Research at the FDA, has been described as “greyhound thin” as a result of his dedication to cycling and lifting weights in the gym each day and, for a long time, a vegetarian diet. I first met him when he was the director of the Office of Oncology Drug Products (ODP) within CDER, in 2009.
