On May 31, 2020 Innovent Biologics, Inc. ("Innovent") (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high quality medicines for the treatment of oncology, autoimmune, metabolic and other major diseases, reported the two-year follow-up results of TYVYT (sintilimab injection) ORIENT-4 study in relapsed or refractory Extranodal NK/T-cell lymphoma (nasal type) at the 56th Annual Meeting of the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) (Abstract # 8050, Poster # 383, 8:00 AM – 11:00 AM, U.S. Central Time, Friday, May 29, 2020) (Press release, Innovent Biologics, MAY 31, 2020, View Source [SID1234558752]).
ORIENT-4 is a multicenter, single-arm, Phase 2 clinical study evaluating the efficacy and safety of sintilimab in relapsed or refractory extranodal NK/T-cell lymphoma (nasal type). A total of 28 subjects were enrolled in the study, all of whom received sintilimab injection (200 mg, IV, Q3W). The study’s primary endpoint was objective response rate (ORR) based on Lugano 2014 response evaluation criteria.
As of January 17, 2020, the ORR was 67.9% and the complete response (CR) rate was 14.3%. The disease control rate (DCR) was 85.7% and the median overall survival (OS) had not been reached, which was 78.6% at two years, with no new safety signals identified.
Professor Jianyong Li, Director of Hematology Department at Jiangsu Provincial People’s Hospital, said "For patients with extranodal NK/T-cell lymphoma (nasal type) that do not respond to a L-asparaginase-containing regimen, there is no internationally recommended treatment regimen, resulting in an urgent clinical need to find effective therapeutic drugs to treat this disease. The results of the ORIENT-4 study showed that the ORR based on Lugano 2014 efficacy evaluation criteria was as high as 67.9% and the two-year OS rate was 78.6%. Sintilimab was statistically demonstrated the significant clinical efficacy in the treatment of relapsed or refractory extranodal NK/T-cell lymphoma (nasal type), and could bring long-term benefits to patients."
