Development program exploring the potential of CBP-174 in the treatment of chronic inflammatory pruritus
SAN DIEGO and TAICANG, SUZHOU, China, May 25, 2021 (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 the first subject has been dosed in a Phase I trial evaluating CBP-174 in healthy adult subjects.
This randomized, double-blind, placebo-controlled, single ascending dose trial in healthy subjects, aims to evaluate the safety, tolerability and pharmacokinetics of CBP-174 in different dose levels given orally, compared to placebo. Following the single dose, each subject will be followed for up to seven days (NCT04811469).
“The effective management of pruritus associated with atopic dermatitis and other inflammatory skin conditions remains a significant unmet medical need, and the advancement of this novel oral agent into Phase I trial is an important step forward in the development of potential therapies,” said Zheng Wei, PhD, Co-founder and CEO of Connect Biopharma. “We believe that CBP-174’s novel mechanism of action and rapid onset of action has the potential to complement the anti-pruritic effect of disease-modifying agents already approved for inflammatory skin diseases.”
About Chronic Inflammatory Pruritus
Chronic inflammatory pruritus is an unpleasant and often persistent itch that can last more than six weeks in duration and is often caused by inflamed skin lesions associated with diseases such as atopic dermatitis (AD). Due to the significant impact that pruritus has on quality of life, its severity is often measured by patients based on intensity of pruritus rather than skin lesions themselves. Common antihistamine drugs primarily target the histamine 1 receptor (H1R) and lead to alleviation of itch in part by blocking H1R on peripheral nerves. However, many types of chronic itch cannot be relieved by current antihistamine treatments that target H1R. Despite currently available treatments for AD, an estimated 40% to 50% of AD patients have inadequate relief of their pruritus and are in need of new, efficacious pruritus therapies.
CBP-174 is a highly potent, orally active, peripherally restricted antagonist of histamine receptor 3 (H3R), designed not to penetrate the blood brain barrier. In preclinical studies, CBP-174 was both well-tolerated and demonstrated significant reductions in scratching bouts within the first 30 minutes of oral or topical dosing, which could potentially translate to rapid relief of itch in the clinic.
About Connect Biopharma Holdings Limited
Connect Biopharma Holdings Limited is a global clinical-stage biopharmaceutical company dedicated to improving the lives of patients living with chronic inflammatory diseases through the development of therapies derived from our T cell-driven research.
Our lead product candidate, CBP-201, is an antibody designed to target interleukin-4 receptor alpha (IL-4Rα) and is currently being evaluated in clinical trials for the treatment of atopic dermatitis (AD) and asthma and in development for chronic rhinosinusitis with nasal polyps (CRSwNP). Our second lead product candidate is CBP-307, a modulator of a T cell receptor known as sphingosine 1-phosphate receptor 1 (S1P1) that is in development for the treatment of ulcerative colitis (UC) and Crohn’s disease (CD). Furthermore, we are developing CBP-174, a peripherally restricted antagonist of histamine receptor 3, for the treatment of pruritus associated with skin inflammation.
With headquarters in China, additional operations in the United States and Australia, and clinical development activities in those geographies as well as Europe, Connect Biopharma is building a rich global pipeline of internally designed, wholly owned small molecules and antibodies targeting several aspects of T cell biology.
