SAN DIEGO, CA and TAICANG, China, Jan. 24, 2022 (GLOBE NEWSWIRE) -- Connect Biopharma Holdings Limited (Nasdaq: CNTB) ("Connect Biopharma" or the “Company”), a global clinical-stage biopharmaceutical company dedicated to improving the lives of patients with chronic inflammatory diseases through the development of therapies derived from T cell-driven research, today announced that data from the global Phase 2b clinical trial of CBP-201 administered subcutaneously (SC) to adult patients with moderate-to-severe atopic dermatitis (AD) (WW001) (NCT04444752), will be presented in two abstracts and posters at the Maui Derm Conference that begins today, January 24^th, and ends January 28^th, in Maui, Hawaii.

The abstracts and posters will expand on the topline results reported by the Company on January 5, 2022, which demonstrated that CBP-201 met the primary and key secondary efficacy endpoints of the trial, with favorable safety data reporting low incidences of injection site reactions, conjunctivitis and herpes infections.

The abstracts and posters will also provide detail of the analyses performed by the Company of patients within the trial with higher baseline disease severity that more closely approaches the disease severity in Phase 3 trials of the approved IL-4R agent. These analyses consistently demonstrate increased efficacy as baseline disease severity increases, indicating that CBP-201 has the potential for a highly competitive efficacy and safety profile that includes a differentiated Q4W dosing schedule.

About Atopic Dermatitis
Atopic dermatitis (AD), which has an estimated lifetime prevalence of up to 20% and is increasing globally, is the most commonly diagnosed chronic inflammatory skin disorder. It is characterized by skin barrier disruption and immune dysregulation. Estimates of prevalence of AD in China show an increase over time and recent longitudinal studies have reported a dermatologist-diagnosed prevalence of 7.8% in Chinese outpatients visiting tertiary hospitals. In the United States, it is estimated that 26.1 million people have AD, of which 6.6 million have moderate-to-severe disease. Further, over 58% of adults with moderate-to-severe AD have disease that physicians consider to be inadequately controlled by approved therapeutic modalities, including topical anti-inflammatory agents and systemic agents.

About CBP-201
CBP-201, discovered internally using Connect Biopharma's proprietary Immune Modulation Technology Platform, is an antibody designed to target interleukin-4 receptor alpha (IL-4Rα), which is a validated target for the treatment of several inflammatory diseases, including atopic dermatitis (AD). CBP-201 was well tolerated and showed evidence of clinical activity in a Phase 2b clinical trial (NCT04444752) in adult patients with moderate-to-severe atopic dermatitis, suggesting a potential for a differentiated efficacy profile compared with data from clinical trials of the current biologic standard of care therapy. CBP-201 is also being evaluated in a China specific pivotal trial in adults with moderate-to-severe atopic dermatitis (NCT05017480); in a Phase 2b trial in adult patients with moderate-to-severe persistent asthma (NCT04773678); and in a Phase 2b trial in adult patients with chronic rhinosinusitis with nasal polyps (CRSwNP) (NCT04783389).
