Trial Outcomes & Findings for Buprenorphine (CAM2038) in Subjects With a Recent History of Moderate to Severe Chronic Low Back Pain (NCT NCT02946073)

NCT ID: NCT02946073

Last Updated: 2021-10-15

Results Overview

Change from baseline in Weekly Average of (Daily) Average Pain Intensity (WAAPI) and the primary timepoint will be Week 12 of the Double-Blind Phase based on the 11-Point numerical rating scale with 0 being no pain and 10 being the worst pain.

Participant Flow

965 of those subjects entered the Double Blind phase of the study. 108 subjects signed consent as De Novo subjects, but 20 of those subjects were part of the Double Blind phase. The total number of subjects that signed consent was 1053 (965 + 88).Two sites had quality issues with the data, so those subjects were eliminated from the analysis. This made the total number of subjects who were analyzed 222 in the double blind randomized phase and 132 subjects for the open label phase.

Subjects are screened prior to entry into a titration phase where they are titrated to an appropriate dose. Once they are titrated, they were randomized and entered the double blind period or open label period for de novo subjects.

PRIMARY outcome

Timeframe: 12 weeks- from randomization baseline to 12 weeks after randomization

Population: Modified Intent-to-Treat (mITT) Population: The mITT Population consisted of all randomized subjects, with the exception of the subjects from Sites 068 and 077 due to persistent site non-compliance

Change from baseline in Weekly Average of (Daily) Average Pain Intensity (WAAPI) and the primary timepoint will be Week 12 of the Double-Blind Phase based on the 11-Point numerical rating scale with 0 being no pain and 10 being the worst pain.

Change from Open Label Titration baseline to Week 12 of the Double-Blind Phase in EuroQol Group 5-dimension 5-level self-report questionnaire score. The EuroQoL Group 5-Dimension 5-Level Self-Report Questionnaire (EQ-5D-5L) descriptive system is a generic, multidimensional, health-related, quality-of-life instrument. The profile allows subjects to rate their health state in 5 health domains: mobility, self-care, usual activities, pain/discomfort, and mood, using a 5-level scale. These combinations of attributes were converted into a weighted health-state index score, according to the US population-based algorithm, with higher scores indicating better quality of life. The score ranges from 0-100 with 0 as the worst health and 100 as the best health.

Change from baseline to Week 12 of the Double-Blind Phase in Work Productivity and Activity Impairment score. The Work Productivity and Activity Impairment (WPAI) is a self-administered instrument used to measure the effect of general health and symptom severity on work productivity and regular activities, and yields 4 types of scores (higher scores indicate greater impairment): Absenteeism (work time missed),Presenteeism (impairment at work/reduced on-the-job effectiveness), Work Productivity Loss (overall work impairment/absenteeism plus presenteeism),and Activity Impairment. Scores range from 0-100 for each of the four types with higher scores indicating greater impairment.

Summary of Change from Baseline in Clinical Global Impression of Improvement (CGI-I) scale. The Clinician Global Impression of Improvement (CGI-I) Scale is a 7-point scale that required the clinician to assess how much the subject's Pain had improved or worsened relative to the start of the study. Assessments were rated as: 1, very much improved; 2, much improved; 3, minimally improved; 4, no change; 5, minimally worse; 6, much worse; or 7, very much worse

Change from baseline in the Open Label Phase in Work Productivity and Activity Impairment score with a range of 0-100 for 4 types of scores with higher scores indicating greater impairment. The Work Productivity and Activity Impairment (WPAI) is a self-administered instrument used to measure the effect of general health and symptom severity on work productivity and regular activities, and yields 4 types of scores (higher scores indicate greater impairment): Absenteeism (work time missed),Presenteeism (impairment at work/reduced on-the-job effectiveness), Work Productivity Loss (overall work impairment/absenteeism plus presenteeism),and Activity Impairment. Scores range from 0-100 for each of the four types with higher scores indicating greater impairment.
