ICP-332 for adults with moderate to severe chronic spontaneous urticaria not controlled by antihistamines

A Phase II/III Randomized, Double-blind, Placebo-controlled, Multi-center Study to Evaluate the Efficacy and Safety of ICP-332 in Moderate to Severe Chronic Spontaneous Urticaria Subjects Inadequately Controlled by Second Generation H1-antihistamines

Phase2; Phase3 Interventional Beijing InnoCare Pharma Tech Co., Ltd. · NCT07378527

This study tests whether ICP-332 tablets can reduce hives and itching in adults (18–75) with moderate to severe chronic spontaneous urticaria that is not controlled by second-generation H1-antihistamines.

What this trial studies

This phase 2/3 interventional study compares ICP-332 tablets with matching placebo in adults whose CSU is inadequately controlled by second-generation H1-antihistamines. Participants must have had CSU for at least six months and meet the trial's inclusion and exclusion criteria before enrollment. Enrolled subjects are assigned to receive ICP-332 or placebo and will be followed for symptom changes and safety outcomes during the treatment period. The study is conducted at several hospital sites in China, including Peking University People's Hospital.

Who should consider this trial

Good fit: Adults aged 18 to 75 with chronic spontaneous urticaria lasting at least six months whose symptoms remain inadequately controlled by second-generation H1-antihistamines are the intended participants.

Not a fit: Pregnant or breastfeeding people, patients with other skin diseases or medical conditions listed in the exclusions, and those whose CSU is well controlled by antihistamines are unlikely to benefit from this study.

Why it matters

Potential benefit: If effective, ICP-332 could reduce hives and itching and improve quality of life for people with CSU who do not respond to standard antihistamines.

How similar studies have performed: Established biologic treatments such as anti-IgE therapy have helped many CSU patients, but ICP-332 is an investigational drug with limited prior human data.
