SAN DIEGO, March 10, 2026 (GLOBE NEWSWIRE) — Connect Biopharma Holdings Limited (Nasdaq: CNTB) (Connect Biopharma, Connect, or the Company), a clinical-stage biopharmaceutical company focused on transforming care for the treatment of inflammatory diseases, today announced that the results of a Phase 3 study of rademikibart in moderate-to-severe atopic dermatitis (AD) conducted by the Company’s partner in China, Simcere Pharmaceutical Co., Ltd. (Simcere), will be presented in the Late-Breaking Research session at the 2026 AAD Annual Meeting, which takes place March 27-31, 2026, in Denver, Colorado.
“We are very encouraged by the acceptance of our partner’s Phase 3 atopic dermatitis study for an oral presentation in the coveted Late-Breaking Research session at AAD this month,” said Barry Quart, Pharm.D., CEO and Director of Connect Biopharma. “We believe the results obtained in this Phase 3 study provide a strong basis for the ultimate approval of Simcere’s pending New Drug Application (NDA) for rademikibart in China. While Connect’s near‑term priorities remain focused on asthma and chronic obstructive pulmonary disease (COPD), the results Simcere has generated in AD underscore rademikibart’s potentially differentiated safety and efficacy and support the opportunity for Connect to target AD as a future indication outside of China. We look forward to the presentation of these findings at AAD later this month.”
Presentation details are as follows:
Title: 79594 – Rademikibart monotherapy in adult and adolescent patients with moderate-to-severe atopic dermatitis (AD): A 1-year, phase III, randomized, double-blinded, placebo-controlled trial (RADIANT-AD)
Date / Time: Saturday, March 28, 2026, from 9:48 – 10:00 a.m. MDT
Location: Bellco Theatre 3
About
Rademikibart
Rademikibart is a fully human monoclonal antibody targeting interleukin-4 receptor alpha (IL-4Rα), a common subunit of interleukin-4 receptor (IL-4) and interleukin-13 receptor (IL-13). We believe that by binding with IL-4Rα, rademikibart can block the functions of IL-4 and IL-13 effectively, thereby blocking the T helper 2 (Th2) inflammatory pathway to achieving the goal of treating Th2-related inflammatory diseases such as atopic dermatitis, asthma and COPD.
