CHOICE-01 Phase III Study of Toripalimab at the Interim Analysis Met Pre-Specified Primary Endpoint of Progression-Free Survival at the First-Line Treatment of Advanced NSCLC

SHANGHAI, China, Dec. 14, 2020 (GLOBE NEWSWIRE) -- Junshi Biosciences (HKEX: 1877; SSE: 688180), an innovation-driven biopharmaceutical company dedicated to the discovery, development and commercialization of novel therapies, is pleased to announce that the Independent Data Monitoring Committee (IDMC) has determined that Toripalimab (product code: JS001) in combination with standard chemotherapy as the first-line treatment of patients with advanced non-small cell lung cancer (NSCLC) has reached its pre-specified primary endpoint of Progression Free Survival (PFS) at the interim analysis of a randomized, double-blind, multi-center, phase III clinical study “CHOICE-01” (Clinicaltrial.gov identifier: NCT03856411). The Company will initiate the process to submit a supplemental New Drug Application (NDA) to the National Medical Products Administration (NMPA) in the near future.

About CHOICE-01 STUDY
The CHOICE-01 Study is a randomized, double-blind, multi-center, phase III clinical study to evaluate the efficacy and safety of Toripalimab versus placebo in combination with standard first-line chemotherapy in patients with previously untreated advanced NSCLC, including both squamous and non-squamous subtypes. Professor Jie Wang from Cancer Hospital Chinese Academy of Medical Sciences is the leading principal investigator for the study.

CHOICE-01 is the first domestic anti-PD-1 chemotherapy combo phase III clinical study that recruits both major histological subtypes of advanced NSCL, the squamous and non-squamous subtypes. The Study enrolled a total of 465 NSCLC patients, including 220 squamous and 245 non-squamous NSCLC patients. The primary endpoint of the study is progression-free survival (PFS), and secondary endpoints include overall survival (OS), objective response rate (ORR), duration of response (DOR), disease control rate (DCR) and safety.

Based on the interim analysis of the Study, the Independent Data Monitoring Committee (IDMC) determined that the primary endpoint of PFS has crossed the pre-defined efficacy boundary. The safety profile of Toripalimab in the study was consistent with the known risks. No new safety signals were identified.
