  • Four poster presentations provided detailed and new data on the achievement of primary and secondary endpoints, improvements in investigator-rated outcomes, and improvements in patient reported outcomes from the initial 16-week treatment period with rademikibart (formerly known as CBP-201) in patients with moderate-to-severe atopic dermatitis (AD) in the pivotal CN002 trial in China

SAN DIEGO and TAICANG, China, July 10, 2023 (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 it presented four posters at the 25th World Congress of Dermatology being held in Singapore from July 3-8, 2023.

“We were excited to share further data regarding rademikibart’s efficacy and safety, from what is the largest readout of an AD trial in China to date.” said Zheng Wei, Ph.D., Co-Founder and Chief Executive Officer of Connect Biopharma. “Rademikibart not only yielded highly significant efficacy responses and was well tolerated, but the improvements seen were consistent across both investigator- and patient-reported outcomes as well. We look forward to the readout at the end of the 36-week maintenance part of the trial by the end of 2023.”

Poster presentation Summaries

Poster presentation 3240#: “Rademikibart (CBP-201), a next-generation IL-4Rα antibody, achieved all primary and secondary endpoints in a randomized pivotal trial for moderate-to-severe atopic dermatitis (AD) in China (CBP-201-CN002)”

This poster presentation reported the Week 16 primary (IGA 0/1) and key secondary efficacy (EASI, PR-NRS, DLQI) outcomes and key safety data demonstrating that rademikibart achieved all endpoints in the primary analysis population of adults with moderate-to-severe AD.

Poster presentation #3242: “Eczema Area and Severity Index (EASI) scores improved, and encouraging safety and tolerability were observed, across 16 weeks of treatment with rademikibart (CBP-201) for moderate-to-severe atopic dermatitis (AD): A pivotal trial in China (CBP-201-CN002)”

This poster included new efficacy data showing highly significant improvement with rademikibart in total EASI score change and in EASI score per AD sign in the primary analysis population, as well as new safety data indicating that rademikibart was well tolerated.

Poster presentation #3247: “Improvements in investigator-rated outcomes across 16 weeks of treatment with rademikibart (CBP-201) for moderate-to-severe atopic dermatitis (AD): Results from a pivotal trial in China (CBP-201-CN002)”

This poster presentation showed the time course of the statistically significant improvements in investigator-assessed outcomes with rademikibart across the initial 16-week treatment period in the adult population. Treatment with rademikibart led to rapid improvements in IGA 0/1, EASI, BSA and SCORAD, all without plateauing by Week 16.

Poster presentation #3243: Improvements in patient-reported outcomes (PROs) across 16 weeks of treatment with rademikibart (CBP-201) for moderate-to-severe atopic dermatitis (AD): Results from a pivotal trial in China (CBP-201-CN002)”

The poster discussed the statistically significant improvements observed in PROs, as assessed by PP-NRS, DLQI and POEM questionnaires, with rademikibart treatment over the initial 16-week treatment period in adult population.

The four poster presentations were available online on the World Congress of Dermatology site starting July 3rd, and in-person at the congress venue during the meeting. Copy of the posters will be made available on Connect Biopharma’s website under the “Our Science” section.
