Is this trial a fit for you?

Likely a good fit

Adults 18–75 with confirmed prurigo nodularis for ≥3 months, bilateral disease with ≥20 lesions, severe itch (PP NRS ≥7), and prior inadequate response to topical corticosteroids are the intended participants.

Probably not a fit

People with mild PN, fewer than 20 lesions, active moderate-to-severe atopic dermatitis, or those unable to attend the listed clinic locations are unlikely to receive benefit from this trial.

What this trial studies

This Phase 2 interventional trial compares ICP-332 to placebo in adults with prurigo nodularis who have widespread bilateral lesions and severe itch. Eligible participants are 18–75 years old, have a clinical diagnosis of PN for at least three months, at least 20 pruriginous lesions with bilateral distribution, a PP NRS score ≥7, and an IGA-CPG-S score ≥3, and a history of inadequate response to medium-or-higher potency topical corticosteroids. Participants will be assigned to receive ICP-332 or placebo and followed for efficacy and safety outcomes, including changes in itch scores and lesion counts. Study sites include clinics in the United States (Ohio) and hospitals in Anhui and Beijing, China, with Beijing InnoCare Pharma Tech as the sponsor.

Why it matters

Potential benefit: If effective, ICP-332 could reduce severe itch and the number of nodules and improve quality of life for people with prurigo nodularis.

How similar studies have gone: Some targeted biologic therapies have shown benefit in prurigo nodularis, but ICP-332 appears to be a novel agent with limited published phase 2 data so far.
