Trial Outcomes & Findings for Safety and Tolerability of Buprenorphine/Naloxone Film Strips (NCT NCT00640835)

NCT ID: NCT00640835

Last Updated: 2012-11-12

Results Overview

Safety and tolerability were evaluated during the 12-week Treatment Phase by oral cavity examination and assessment. Oral mucosa was graded as follows: Grade 0: Normal mucosa Grade 1: Localized mucosal erythema and/or irritation without ulceration Grade 2: Erythema and/or irritation and induration without ulceration Grade 3: Ulceration, with or without any other combination of signs

PRIMARY outcome

Timeframe: 12 weeks

Population: The population was defined as all subjects who received at least a single dose of study drug and was the only population considered in the analysis plan. Missing data values were not imputed.

Safety and tolerability were evaluated during the 12-week Treatment Phase by oral cavity examination and assessment. Oral mucosa was graded as follows: Grade 0: Normal mucosa Grade 1: Localized mucosal erythema and/or irritation without ulceration Grade 2: Erythema and/or irritation and induration without ulceration Grade 3: Ulceration, with or without any other combination of signs
