Ziihera received accelerated approval based on results including a 52% objective response rate and median duration of response of 14.9 months as determined by independent central review (ICR) from the HERIZON-BTC-01 clinical trial.
Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial. The Phase 3 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 biliary tract cancer (BTC).
Jazz cautioned that exposure to Ziihera during pregnancy may cause embryo-fetal harm. Patients should be advised of this risk and the necessity of using effective contraception.
According to the company, Zanidatamab is also being investigated in a number of additional tumor types, including Phase 3 trials in gastroesophageal adenocarcinomas (GEAs) and metastatic breast cancer (mBC).
