Trial Outcomes & Findings for Study to Evaluate the Effect of AFQ056 in Obsessive Compulsive Disorder (OCD) Patients Resistant to Selective Serotonin Reuptake Inhibitor (SSRI) Therapy (NCT NCT01813019)

NCT ID: NCT01813019

Last Updated: 2017-01-02

Results Overview

The Y-BOCS is a 10 item clinician-rated scale used to both determine the severity of OCD and to monitor symptom improvement throughout the course of the study. The Y-BOCS, specifically measures the severity of symptoms of OCD without being biased towards the type of obsessions or compulsions present. The scale includes questions about the amount of time spent on, how much impairment or distress experienced from, and how much resistance and control over these obsessive thoughts and compulsions. Each item is rated from 0 ("no symptoms") to 4 ("extreme symptoms") and yields a total possible score range from 0 to 40, with the following ranges indicating degree of severity: 0-7 = sub-clinical 8-15 = mild 16-23 = moderate 24-31 = severe 32-40 = extreme Baseline was compared to week 17 (end of week 16 dosing) to produce an absolute change.

PRIMARY outcome

Timeframe: baseline, week 17

Population: Pharmacodynamics (PD) analysis set only participants that were analyzed at baseline and Week 17. Positive change from baseline indicates a decrease in symptom severity

SECONDARY outcome

Timeframe: 16 weeks

Population: The study was terminated due to an interim analysis of the primary efficacy outcome. Study was prematurely terminated at the time of the first Interim Analysis (IA) as the study did not meet its primary efficacy objective therefore secondary objective was not measured.

If a subject demonstrates at least 25% reduction in total Y-BOCS from Baseline then they will be classed as a responder whereas if a subject has a reduction in Y-BOCS of less than 25% then they will be categorized as a nonresponder.
