New Reference: Toripalimab with Chemotherapy for Advanced Esophageal SCC

In the JUPITER-06 trial, toripalimab combined with chemotherapy significantly improved overall and progression-free survival in patients with advanced esophageal squamous cell carcinoma. The treatment was well tolerated, with similar safety profiles between the groups.

  • Study

    Randomized, double-blind, placebo-controlled, phase 3 study [JUPITER-06]
