Innovent Announces First Patient Dosed in a Phase 3 Clinical Trial (CLEAR) of Picankibart (Anti-IL23p19 Monoclonal Antibody) in Patients with Moderate-to-Severe Plaque Psoriasis

ROCKVILLE,Md. and SUZHOU,China,Feb. 16,2023 -- Innovent Biologics,Group. ("Innovent") (HKEX: 01801),a world-class biopharmaceutical company that develops,manufactures and commercializes high quality medicines for the treatment of oncology,metabolic,autoimmune,ophthalmology and other major diseases,announced that the first patient with moderate-to-severe plaque psoriasis has been successfully dosed in a Phase 3 clinical trial (CLEAR) of picankibart (R&D code: IBI112),a recombinant anti-interleukin 23p19 subunit (IL23p19) antibody injection.

The CLEAR study (clinicaltrials.gov,NCT05645627) is a multicenter,randomized,double-blind,placebo-controlled phase 3 clinical study to evaluate the efficacy and safety of picankibart in patients with moderate to severe plaque psoriasis. This study plans to enrollapproximately 500 subjects withmoderate to severe plaque psoriasis. After 4 weeks of screening,subjects who met the eligibility criteria of the study will be randomized in a 2:2:1 ratio to picankibart group 1 (initial dose of 200mg and subsequently 200mg every 12 weeks thereafter),picankibart group 2 (initial dose of 200mg and subsequently 100mg every 12 weeks thereafter),or placebo group. The research period is expected to be 68 weeks.

The CLEAR study is the first phase 3 clinical study of IL-23 class innovative drugs in China. Innovent will continue to leverage its leading position in clinical development and guarantee the high quality of innovative drugs,and strive to provide better treatment options for psoriasis patients as soon as possible.

Professor Yuling Shi of Shanghai Skin Disease Hospital,the Principal Investigator of the Study,stated,"Psoriasis is not only a skin disease,but also a systemic disease,withmillions ofpatients in China. Due to the slow progression of the disease,the vast majority of patients require long-term treatment or even lifelong medication. The disease itself and its co-morbidities have a significant impact on the patient's quality of life,and even physical and psychological health. However,currently,for Chinese patients,the treatment needs are far from being met. Picankibart is a biological independently developed in China. Data from phase 2 clinical study have shown significant clinical benefit and improvement in quality of life for patients treated with picankibart. We look forward to the efficacy of picankibart in phase 3 clinical study,and also look forward to the launch of more domestic innovative drugs,benefiting more patients in China."

Dr. Qian Lei,Vice President of Clinical Development of Innovent,stated:"The new generation of drugs targeting IL-23 has shown excellent efficacy and good safety,especially compared with anti-IL-17 monoclonal antibody drugs. The long-term efficacy of IL-23p19 antibody drugs has made it a new choice for the treatment of psoriasis. Picankibart,independently developed by Innovent,is the first anti-IL23p19 antibody drug which has completed phase 2 clinical study in Chinese patients with moderate-to-severe plaque psoriasis,and has obtained good efficacy and safety results. It also showed the obvious advantages of long-dose interval and long-term efficacy. At week52,66.7%~86.0% of the subjects who received picankibart achieving PASI90; 81.6%~88.0% of the subjects achieved PASI 75,and in one of the groups received picankibart,about 48.0 % of subjects achieved complete skin lesions clearance (PASI 100). Compared with current drugs on the market，picankibart shows a great potential for both efficacy and safety,and could be offered as a more optimal treatment option. Based on this,we are fully confident and will make all the efforts to advance the development of the CLEAR study,and plan to synchronize the use of the auto-injector in this study. We are striving to provide more convenient,user-friendly and effective treatment options for patients with moderate and severe plaque psoriasis as soon as possible".

About Picankibart (Anti-IL23p19 Monoclonal Antibody)

Picankibart (R&D code: IBI112) is a monoclonal antibody independently developed by Innovent,with independent intellectual property rights. This product specifically binds to IL-23p19 subunit,thereby preventing IL-23 from binding to cell surface receptors,resulting in the inhibition of the IL-23 receptor-mediated signaling pathway. Preclinical data demonstrated that picankibart has a clear target and well-elucidated mechanism of action and significant anti-inflammatory effect. Further,good safety and tolerability have been demonstrated in the phase 1 clinical study，and confirmed in the completed phase 2 clinical study,showing long-dose interval and long-term efficacy advantages. Picankibart is expected to provide more effective treatment options for patients with autoimmune diseases,including psoriasis.

About Psoriasis

Psoriasis is a chronic,recurrent,inflammatory and systemic disease mediated by both genetic and environmental factors,which can occur in all age groups with no gender preference. The typical clinical presentation includes scaly erythema or plaque with non-infections,localized or widespread distribution. It is a life-long noninfectious condition,which is very difficult to treat. Psoriasis can be classified into psoriasis vulgaris (including guttate psoriasis and plaque psoriasis),pustular psoriasis,erythrodermic psoriasis and arthropathic psoriasis. Approximately,80~90% of patients have plaque psoriasis,and nearly 30% of the cases are moderate and severe. There are significant differences in the prevalence of psoriasis around the world,with more than 6 million patients in China. At present,in China,the main systemic treatments include methotrexate (MTX),cyclosporine A,retinoic acids and biological agents. Since 2019,first-line treatment of psoriasis in China has gradually entered the era of biological agents.
