Innovent Biologics and Lilly Jointly Announced the Long-Term Follow-Up Results of TYVYT® (Sintilimab Injection) in the Treatment of Patients with Relapsed/Refractory Classic Hodgkin's Lymphoma

SUZHOU,China,May 31,2020 --Innovent Biologics,Inc. (Innovent) (HKEX: 01801),a world-class biopharmaceutical company that develops,manufactures and commercializes high quality medicines,jointly announced with Eli Lilly and Company (Lilly) (NYSE: LLY) the research results of TYVYT® (sintilimab injection) ORIENT-1 study for the treatment of relapsed or refractory classic Hodgkin's lymphoma (r/r cHL),at the 56th Annual Meeting of the American Society of Clinical Oncology (ASCO) (Abstract # 8034,Poster # 367,8:00 AM – 11:00 AM,U.S. Central Time,Friday,May 29,2020).

The ORIENT-1 study is a multicenter,single-arm,Phase 2 clinical trial,assessing the efficacy and safety of sintilimab in r/r cHL. Subjects received 200 mg of sintilimab every three weeks in this study until disease progression. A total of 96 subjects with r/r cHL were enrolled,and the study's primary endpoint was objective response rate (ORR) assessed by an independent imaging assessment committee (IRRC). In addition,the complete response (CR) rate was a secondary endpoint in the ORIENT-1 study.

As of the data cutoff on September 30,2019,the ORR was 85.4% (82/96) based on IRRC review,of which 41 patients (42.7%) achieved complete response (CR). Professor Yuan-kai Shi,Associate Dean from the Cancer Hospital of the Chinese Academy of Medical Sciences and Director of the Department of Oncology,said: "Treatment options for patients with r/r cHL remain limited,and new drugs with long-lasting efficacy and good safety are urgently needed. The results of long-term follow-up of the ORIENT-1 study showed that sintilimab can bring relatively more long-term benefits to r/r cHL patients."
