Trial Outcomes & Findings for A Study of CLE-400 (Topical Gel) for the Treatment of Chronic Pruritus in Adult Subjects With Notalgia Paresthetica (NCT NCT06262607)

NCT ID: NCT06262607

Last Updated: 2025-11-18

Results Overview

The WI-NRS is a tool used to assess the intensity of the most severe (worst) pruritus (itch), as experienced by the subject, in the last 24 hours. WI-NRS scale score ranges from 0 to 10, with 0 indicating no itch and 10 indicating the worst itch imaginable.

PRIMARY outcome

Timeframe: Baseline, Week 4 (28 days).

Population: The FAS is a subset of the ITT analysis set and will include all randomized subjects who received at least 1 dose of study treatment and have both baseline and at least one post-baseline weekly mean WI-NRS evaluation. In this analysis set, treatment is assigned based on the treatment to which subjects were randomized, regardless of which treatment they actually received. The FAS serves as the principal analysis set for efficacy inference.

The WI-NRS is a tool used to assess the intensity of the most severe (worst) pruritus (itch), as experienced by the subject, in the last 24 hours. WI-NRS scale score ranges from 0 to 10, with 0 indicating no itch and 10 indicating the worst itch imaginable.
