Abstract
Background and Aim: In the phase 3 CONCUR trial (NCT01584830), regorafenib improved overall survival (OS) versus placebo in Asian patients with treatment-refractory metastatic colorectal cancer (mCRC). We conducted a post hoc subgroup analysis of Chinese patients in CONCUR. Methods: Adults with mCRC progressing despite at least two prior treatment regimens and Eastern Cooperative Oncology Group performance status 0–1 were randomized 2:1 to regorafenib 160?mg once daily or placebo for the first 3?weeks of each 4-week cycle. Dose modifications were permitted. The primary endpoint was OS. Secondary endpoints included progression-free survival, objective overall response, disease control rate, and safety. Results: A total of 172 Chinese patients were randomized and treated (regorafenib n?=?112, placebo n?=?60). OS was significantly improved with regorafenib versus placebo (8.4 vs 6.2?months, respectively; hazard ratio [HR] 0.56, 95% CI 0.39–0.80; one-sided P?=?0.000632), as was progression-free survival (HR 0.32, 95% CI 0.22–0.47; one-sided P?
