NCT ID: NCT01927055

Last Updated: 2016-01-08

Results Overview

OHSA item 1 scale range: 0 (none) -10 (worst), likert scale. Change: score at end of study minus score at randomization. A positive score indicates worsening during the double-blind randomized phase relative to value at randomization, while a negative score indicates an improvement in symptom severity.

PRIMARY outcome

Timeframe: Change from Randomization to Week 1

Population: Patients entering the double-blind, randomized phase and having a visit at week 1 of the double-blind phase were analyzed. Study was stopped when only 5% of planned participants had completed the study to prevent competition with FDA mandated post-marketing requirement study.

OHSA item 1 scale range: 0 (none) -10 (worst), likert scale. Change: score at end of study minus score at randomization. A positive score indicates worsening during the double-blind randomized phase relative to value at randomization, while a negative score indicates an improvement in symptom severity.
