Trial Outcomes & Findings for A 10-week Efficacy Study of NOE-105 in Childhood Onset Fluency Disorder (Orpheus) (NCT NCT05583955)

NCT ID: NCT05583955

Last Updated: 2026-02-20

Results Overview

MLGSSS refers to Maguire-Leal-Garibaldi Self-rated Stuttering Scale. The scale includes ten questions that are assessed on a 0 to 10 scale with 0 being no impact and 10 being highest impact. The total score ranges from 0 to 100 with the higher the score the worse the stuttering.

PRIMARY outcome

Timeframe: 43 days

Population: The full analysis set was used to assess the outcome. The full analysis set includes patients randomized who had at least one dose of study treatment and post randomization MLGSSS assessed.

MLGSSS refers to Maguire-Leal-Garibaldi Self-rated Stuttering Scale. The scale includes ten questions that are assessed on a 0 to 10 scale with 0 being no impact and 10 being highest impact. The total score ranges from 0 to 100 with the higher the score the worse the stuttering.

The Sheehan Disability Scale (SDS) is a brief, self-report tool that assesses disability or functional impairment in the domains of (1) Work/School life, (2) Social life, and (3) Family life/home responsibilities. Each is assessed on a 10 point scale with 0 being no impact, and 10 being highest impact. Each item is rated from 0 (not at all) to 10 (extremely) impairment. Each domain score is added to provide a total score from 0-30 total score with 0 (no impairment) and 30 is severe impairment. The change from the Baseline assessment have been provided.

MLGSSS refers to Maguire-Leal-Garibaldi Self-rated Stuttering Scale. The scale includes ten questions that are assessed on a 0 to 10 scale with 0 being no impact and 10 being highest impact. The total score ranges from 0 to 100 with the higher the score the worse the stuttering. Analysis of a subset of participant with a Baseline MLGSSS of \> 24, in other words this analysis excludes those with mild stuttering as measured by MLGSSS. See the description for the first outcome measure for a description of the scale. The results show the change from baseline.
