SAN FRANCISCO and SUZHOU, ChinaSept. 23, 2021 /PRNewswire/ -- Innovent Biologics Group. ("Innovent") (HKEX: 01801), a world-class biopharmaceutical company that develops, manufactures and commercializes high quality medicines for the treatment of cancer, metabolic, autoimmune and other major diseases, today announced that the first patient with moderate-to-severe plaque psoriasis has been successfully dosed in a Phase 2 clinical trial (clinicaltrials.gov, NCT05003531) of recombinant anti-interleukin 23p19 subunit antibody injection (R & D code: IBI112) in China.

Study CIBI112A201 is a multicenter, randomized, double-blind, parallel, placebo-controlled Phase 2 clinical trial, evaluating the efficacy and safety of IBI112 at different doses administered subcutaneously in the treatment of moderate-to-severe plaque psoriasis. The primary objective of the study is to evaluate the efficacy of subcutaneous injection of IBI112 at different doses in Chinese subjects with moderate-to-severe plaque psoriasis. The safety of drugs and the difference of administration interval between different therapeutic regimens will also be investigated, so as to provide dose information for Phase 3 clinical studies. This is also the first Phase 2 clinical study of domestic innovative drugs targeting IL-23p19, which is a significant milestone.

Professor Jianzhong Zhang from Peking University People's Hospital, principal investigator of the study, stated, "The pathogenesis of psoriasis is complex. Psoriasis is difficult to treat, and the patients often suffer for a lifetime. Currently about 2% to 3% of the world's population suffers from psoriasis; about 80% to 90% of patients have plaque psoriasis, and nearly one third of the cases are moderate to severe. There are about 6 million patients with psoriasis in China. According to the literature, IL-23 monoclonal antibody has gained increasing attention in recent years due to its favorable efficacy and safety profiles. IBI112 is a novel IL-23p19 monoclonal antibody independently investigated and developed by Chinese enterprises. The results of Phase 1 clinical trial showed favorable safety and tolerability as well as potential advantages in the route of administration. We hope that IBI112 will be successful in the Phase 2 clinical trial, and provide an alternative treatment option for Chinese patients with psoriasis."

Dr. Qian Lei, Executive Director of Medical Sciences and Strategies of Special Diseases of Innovent, stated: "With the introduction of biologics drugs such as adalimumab and IL-17 into the clinic, compared with traditional systemic treatments, they undoubtedly offer alternative treatment options for patients with psoriasis, but there is still room for further improvement in terms of efficacy, safety, as well as maintaining a durable effect. Recently, a new generation of drugs targeting IL-23 has attracted special interests due to its excellent efficacy and favorable safety profile. IL-23 plays a key role in T cell-mediated response and is regarded as a pivotal initiator of immune-mediated diseases. In contrast to IL-17 monoclonal antibody, antibodies against IL23p19 have significant advantages in terms of generating a durable effect. IBI112 plays an anti-inflammatory role by blocking IL-23-mediated signaling pathway and has the potential to treat autoimmune diseases such as psoriasis and inflammatory Bowel disease (IBD). Currently, there is no self-developed IL-23p19 inhibitors on the market in China. Results from the first-in-human Phase 1 clinical study of IBI112 has confirmed its favorable safety and tolerability profiles, and has preliminarily demonstrated its potential to serve a more patient-friendly treatment regimen. We are greatly encouraged that it can provide strong foundation for the subsequent clinical development. Based on this, in collaboration with our study sites, we are confident to advance the clinical development of IBI112 in moderate to severe plaque psoriasis as well as other indications to fulfill our mission of providing high-quality innovative biopharmaceuticals that are accessible to the vast majority of patients
