SAN DIEGO, CA and TAICANG, SUZHOU, China, Aug. 31, 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 financial results for the six months ended June30, 2021 and recent corporate highlights.

The first half of 2021 marked the achievement of a number of key milestones for Connect, including the transition to a public company with our oversubscribed Nasdaq Initial Public Offering in March 2021, strong execution and progress on our development programs with our three lead assets now in the clinic targeting multiple chronic inflammatory diseases, and advancing our operational capabilities as we continue to attract key talent in both China and the U.S., said Zheng Wei, PhD, Co-founder and CEO of Connect Biopharma. For the remainder of 2021, despite the uncertainties related to the COVID-19 pandemic, we remain confident in executing against our corporate strategy and we look forward to important clinical trial data readouts toward the end of this year that we believe will validate our approach in developing potential first-in-class or best-in-class therapies for T cell-driven inflammatory diseases.

First Half 2021 and Recent Operating Highlights

-- Completed successful listing on Nasdaq: In March 2021, Connect Biopharma completed an IPO of American Depositary Shares on the Nasdaq Global Select Market and commenced trading under the ticker symbol CNTB. The Company raised net proceeds of approximately USD 204.5million. -- Completed enrollment of Phase 2 trial of CBP-201 in moderate-to-severe atopic dermatitis (AD): In April 2021, Connect Biopharma completed full enrollment of the Phase 2 clinical trial evaluating CBP-201 in adult patients with moderate-to-severe AD. The global, randomized, double-blind, placebo-controlled, dose-ranging clinical trial is intended to assess the efficacy, safety, and pharmacokinetics (PK) profile of CBP-201 in 220 subjects and is being conducted at 60 sites across the U.S., China, Australia, and New Zealand. CBP-201 or placebo was administered to eligible adult subjects with moderate-to-severe AD for 16 weeks with eight weeks of follow up. -- Dosed first patient in Phase 2 trial of CBP-201 in moderate-to-severe persistent asthma: In May 2021, dosed the first patient in a global Phase 2 clinical trial evaluating CBP-201 in adults with moderate-to-severe persistent asthma. This multicenter, randomized, double-blind, parallel group, placebo-controlled trial was designed to assess the efficacy and safety of two doses of CBP-201 administered subcutaneously (SC) to eligible patients with moderate to severe persistent asthma with Type 2 inflammation. The trial is expected to enroll approximately 300 patients across 80 clinical sites in the United States, China, the European Union, the United Kingdom, Ukraine and South Korea and is divided into a treatment period of 24 weeks and a follow-up period of eight weeks. -- Dosed first subject in Phase 1 trial of CBP-174: In May 2021, Connect Biopharma dosed the first subject in a Phase 1 clinical trial evaluating CBP-174 in the treatment of chronic inflammatory pruritus. This randomized, double-blind, placebo-controlled, single ascending dose trial in healthy subjects, aims to evaluate the safety, tolerability and PK 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. -- Expanded senior leadership team: Announced that Mr.Yau Wing Yiu (Felix) joined Connect Biopharma as Vice President, Finance and Mr.Jiang Bian as General Counsel and Chief Compliance Officer. -- Appointed Jean Liu, J.D., as Independent Director to the Board: Ms.Liu is an Executive Vice President, Legal Affairs, General Counsel and Secretary of Seagen Inc., a targeted cancer therapeutic company.

Anticipated Upcoming Milestones
