Official Title
A Phase III, Randomized, Double-Blind, Placebo-Controlled Study of Atezolizumab Plus Tiragolumab in Combination With Paclitaxel and Cisplatin Compared With Paclitaxel and Cisplatin as First-Line Treatment in Patients With Unresectable Locally Advanced, Unresectable Recurrent, or Metastatic Esophageal Squamous Cell Carcinoma
Study Summary
The purpose of this study is to evaluate the efficacy and safety of atezolizumab plus tiragolumab in combination with paclitaxel and cisplatin (PC) compared with atezolizumab matching placebo plus tiragolumab matching placebo plus PC as first-line treatment in participants with unresectable locally advanced, unresectable recurrent, or metastatic esophageal carcinoma (EC). Participants will be randomized in a 1:1 ratio to receive one of the following treatment regimens during induction phase: Arm A: Atezolizumab plus Tiragolumab and PC Arm B: Atezolizumab placebo plus Tiragolumab placebo and PC Following the induction phase, participants will continue maintenance therapy with either atezolizumab plus tiragolumab (Arm A) or atezolizumab matching placebo plus tiragolumab matching placebo (Arm B).
