SAN DIEGO, CA and TAICANG, SUZHOU, China, March 31, 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 inflammatory diseases through the development of therapies derived from T cell-driven research, today announced financial results for the full year ended December 31, 2021 and recent corporate highlights.

“During the past year, we advanced the clinical development of our lead assets CBP-201 and CBP-307, each having potentially differentiated product profiles for atopic dermatitis, asthma, chronic rhinosinusitis with nasal polyps, and ulcerative colitis, diseases with large patient populations with significant unmet need,” said Zheng Wei, PhD, Co-founder and CEO of Connect Biopharma. “Our data from the global Phase 2b trial of CBP-201 in patients with atopic dermatitis gives us confidence in the potential that CBP-201 could have a highly competitive efficacy and safety profile with low incidence of conjunctivitis, and the convenience of dosing every four weeks. In the coming 12 months, we have a number of key milestones anticipated for CBP-201, including initiating our global Phase 3 program in atopic dermatitis and completing enrollment in both our pivotal trial in atopic dermatitis in China, and in our Phase 2 trial in asthma. We also look forward to reporting topline results from our Phase 2 trial of CBP-307 in patients with moderate-to-severe ulcerative colitis in the first half of 2022.”

Second H a l f 2 0 2 1 and Rec e nt Operati n g H i g hlig h t s

• Reported positive data from global Phase 2b trial of CBP-201 in moderate-to-severe atopic dermatitis (AD) : In January 2022, the Company reported detailed positive data from the global Phase 2b clinical trial of CBP-201 administered subcutaneously to adult patients with moderate-to-severe AD. CBP-201 met all primary and key secondary efficacy endpoints, with favorable safety data reporting low incidences of injection site reactions, conjunctivitis and herpes infections. In the coming months, the Company intends to discuss these data with the U.S. Food & Drug Administration (FDA) and other regulatory authorities to seek feedback on its planned global Phase 3 program. The Company plans to commence enrollment of the global Phase 3 program in the second half of 2022.
  
  
• Co m pleted enrollment of P hase 2 t r i al o f C B P -307 i n mode r at e - t o -severe ulcerative colitis (UC) : In November 2021, the Company completed full enrollment of the Phase 2 clinical trial evaluating CBP-307 in moderate-to-severe UC. The global, randomized, double-blind, placebo-controlled trial is being conducted at multiple sites, including in China and the U.S., to evaluate the efficacy and safety of CBP-307 in 144 patients, where CBP-307 or placebo were administered to eligible adult patients for 12 weeks (induction phase). Following this 12-week induction phase, treatment responders (as defined by change in the adapted Mayo score from baseline) are expected to be treated for an additional 36 weeks in a double-blind manner, and non-responders are expected to enter an open-label arm and be treated for an additional 36 weeks (maintenance phase).
  
  
• Dos e d first patient in China-specific pivotal trial of C B P- 201 in moderate-to-severe AD : In September 2021, the first patient in a China-specific pivotal trial evaluating CBP-201 with moderate-to-severe AD was dosed. The multi-center, randomized, double-blind, parallel group, placebo-controlled trial was designed to assess the efficacy and safety of up to two doses of CBP-201 administered subcutaneously. The trial has completed its original enrollment of 255 patients across 55 clinical sites in China, which was divided into an initial treatment period of 16 weeks, a maintenance period of 36 weeks and a follow-up period of eight weeks. The Company plans to increase the trial size to approximately 500 patients in order to meet anticipated regulatory requirements around trial size and safety exposures and expects to finalize its trial design with China regulatory authorities by the second half of 2022.
  
  
• Dos e d first patient in P h a se 2 t rial o f CB P - 20 1 in chronic rhinosinusitis with nasal polyps (CRSwNP) : In September 2021, the first patient in a Phase 2 trial evaluating CBP-201 in CRSwNP was dosed. The multi-center, randomized, double-blind, placebo-controlled trial is designed to evaluate the effect of CBP-201 administered subcutaneously on a background of mometasone furoate nasal spray in reducing endoscopic nasal polyp score and nasal congestion/obstruction score severity in eligible patients whose disease remains inadequately controlled despite daily treatment with intranasal corticosteroid therapy in comparison to placebo. The trial is divided into a treatment period of 24 weeks and a follow-up period of eight weeks and is expected to enroll approximately 140 patients with CRSwNP across approximately 60 clinical sites in the United States, China, Europe, and other regions.
  
  
• Expanded executive leade r ship t e a m : Autoimmune and immunology expert, Chin Lee, MD, MPH, and Steven Chan joined Connect Biopharma as Chief Medical Officer and Chief Financial Officer, respectively.
  

Antici p a t e d 2022 Milestones

• On track to report top-line results from the global Phase 1 trial evaluating safety and pharmacokinetics of CBP-174 in healthy volunteers in the first half of 2022.
  
  
• Plan to complete enrollment for the global Phase 2 trial of CBP-201 in asthma patients in the first half of 2022.
  
  
• Plan to initiate a global Phase 3 trial for CBP-201 in moderate-to-severe AD patients in the second half of 2022.
  
  
• Plan to complete enrollment for the China-specific pivotal trial for CBP-201 in AD patients in the second half of 2022.
  

Full Year 2 0 2 1 Fin a nc i a l Results

• Cash and cash equivalents were RMB 1,706.9 million (USD 267.7 million) as of December 31, 2021, compared to RMB 1,010.1 million as of December 31, 2020. The increase in cash and cash equivalents was mainly due to proceeds received from the Company’s IPO in March 2021.
  
  
• Research and development expenses increased to RMB 518.0 million (USD 81.2 million) for the year ended December 31, 2021, from RMB 150.9 million in the year ended December 31, 2020. This increase was driven primarily by higher clinical trial related expenses for advancing CBP-201 in adult patients with moderate-to-severe AD into later clinical trial phases and additional drug supply and clinical expenses related to the initiation of global Phase 2 clinical trials of CBP-201 for asthma and CRSwNP indications and the initiation of a global Phase 2 trial for CBP-307 in UC and Crohn’s Disease (CD) indications.
  
  
• Administrative expenses increased to RMB 122.4 million (USD 19.2 million) for the year ended December 31, 2021, from RMB 47.7 million in the year ended December 31, 2020. The increase was primarily due to higher personnel costs, including stock-based compensation expenses, higher professional services and other costs associated with building out a public company infrastructure and supporting clinical trials.
  
  
• Net loss was RMB 1,306.8 million (USD 205.0 million) for the year ended December 31, 2021, compared to RMB 779.2 million in the year ended December 31, 2020.
