The FDA has delayed the decision to approve tislelizumab monotherapy for patients with advanced or metastatic esophageal squamous cell carcinoma following prior systemic therapy, due to COVID-19 travel restrictions.

Howard A. Burris, MD, highlighted previous findings of the phase 3 TOPAZ-1 trial assessing durvalumab plus gemcitabine and cisplatin vs placebo plus gemcitabine and cisplatin in advanced biliary tract cancer and patient-reported outcomes data that were presented at 2022 ASCO.
