About the CheckMate -577 study (ONO-4538-43)
The CheckMate -577 study is a global, multicenter, randomized, double-blind, phase 3 clinical study evaluating Opdivo as monotherapy as adjuvant therapy in patients with resected esophageal cancer (ESC) or cancer of the gastroesophageal junction (CJGE) who received neoadjuvant radiochemotherapy (CRT) and did not obtain a complete pathological response. After neoadjuvant CRT and complete surgical resection of the tumor (also known as trimodal therapy), patients were randomized to receive Opdivo or placebo. In patients receiving Opdivo, it was given 240 mg every two weeks for 16 weeks, followed by Opdivo 480 mg every four weeks until disease recurrence, unacceptable toxicity or withdrawal of consent, with maximum total treatment time of one year. The primary endpoint of the study is disease-free survival (SSM) and the secondary endpoint is overall survival (OS).
