Trial overview
The available trial data describe one interventional study of 3-[(3AS,6AR)-5-{5-CHLORO-2-[(1-METHYL-1H-PYRAZOL-4-YL)AMINO]PYRIMIDIN-4-YL}-3A-METHYLHEXAHYDROPYRROLO[3,4-C]PYRROL-2(1H)-YL]-3-OXOPROPANENITRILE in prurigo nodularis, a condition with severe itching and skin nodules.[1]
The study brief says the goal is to evaluate treatment efficacy of ICP-332 versus placebo in adult participants with PN.[1]
Who can participate
The trial is for adult participants with prurigo nodularis.[1]
No other eligibility details are provided in the trial record, so the available data do not list extra requirements such as prior treatments, severity limits, or other health conditions.[1]
Study design and phase
This is a Phase 2 study, which usually means the research is checking whether the treatment may help and continuing to watch safety.[1]
The trial is described as randomized, double-blind, placebo-controlled, and dose-ranging.[1]
Randomized means participants are assigned by chance to treatment groups, double-blind means neither participants nor the study team know who gets which treatment, placebo-controlled means the study compares the active treatment with an inactive look-alike, and dose-ranging means more than one dose is being explored.[1]
The intervention list shows placebo and 3-[(3AS,6AR)-5-{5-CHLORO-2-[(1-METHYL-1H-PYRAZOL-4-YL)AMINO]PYRIMIDIN-4-YL}-3A-METHYLHEXAHYDROPYRROLO[3,4-C]PYRROL-2(1H)-YL]-3-OXOPROPANENITRILE given orally at 120 mg.[1]
What is being measured
The main endpoint is the percent change from baseline in the weekly average of the Peak pruritus-numeric rate scale (PP NRS) at Week 16.[1]
In simple words, the study is measuring how much itching changes after treatment compared with the starting point, using a score designed to track itch severity.[1]
Trial status and size
The trial status is Authorised, and the planned enrollment is 135 participants.[1]
This gives a clear picture of a mid-stage study in a defined adult population with prurigo nodularis, focused on whether the treatment can reduce itching better than placebo.[1]
