Trial Outcomes & Findings for Treatment Seeking Participants With Opioid Use Disorders Assessing Tolerability of Depot Injections of Buprenorphine (NCT NCT02357901)

NCT ID: NCT02357901

Last Updated: 2018-02-20

Results Overview

Data represent the count of participants at various percentage abstinence levels. Abstinence was defined as urine samples being negative for opioids AND negative self-reports (obtained from Timeline Followback (TLFB) interviews) for illicit opioid use. The primary endpoint was based on visits in which paired urine samples and self-reports were expected for each subject as specified in the schedule of events. Missing urine drug screen(s) (UDS) samples and/or self-reports were considered as non-negative.

Run-In Period
During the Run-In Period, participants were inducted onto SUBOXONE sublingual film followed by a 4- to 11-day SUBOXONE sublingual film open-label run-in dose-adjustment period to achieve buprenorphine dosages ranging from 8 to 24 mg according to the SUBOXONE sublingual film prescribing information.
RBP-6000 300mg/100mg
Participants were given RBP-6000 300 mg injections on Days 1 and 29. Injections 3-6 were separated by 28 days (Day 57-Day 141) and contained RBP-6000 100 mg. As of protocol Amendment 2 (21 August 2015) SUBOXONE sublingual film use was tapered from 6 mg to 2 mg from Days 1-5 and then discontinued. In addition, participants received individual drug counseling (IDC) at least once a week.
RBP-6000 300mg/300mg
Participants were given six RBP-6000 300 mg injections on Days 1 to 141 with injections separated by 28 days. As of protocol Amendment 2 (21 August 2015) SUBOXONE sublingual film use was tapered from 6 mg to 2 mg from Days 1-5 and then discontinued. In addition, participants received individual drug counseling (IDC) at least once a week.
Combined Placebo
Participants randomized to either of the two placebo treatment arms were combined into this one treatment arm for reporting purposes. Analyses of 13-0001 were planned, conducted, and reported with pooled placebo groups. These participants were given six volume-matched placebo injections on Days 1 to 141 with injections separated by 28 days. As of protocol Amendment 2 (21 August 2015) SUBOXONE sublingual film use was tapered from 6 mg to 2 mg from Days 1-5 and then discontinued. In addition, participants received individual drug counseling (IDC) at least once a week.

PRIMARY outcome

Timeframe: Weekly from Weeks 5-24

Population: Full analysis set

Data represent the count of participants at various percentage abstinence levels. Abstinence was defined as urine samples being negative for opioids AND negative self-reports (obtained from Timeline Followback (TLFB) interviews) for illicit opioid use. The primary endpoint was based on visits in which paired urine samples and self-reports were expected for each subject as specified in the schedule of events. Missing urine drug screen(s) (UDS) samples and/or self-reports were considered as non-negative.

Population: Full analysis set of participants who had available data on baseline score and change from baseline in any visit through week 24.

The opioid craving scale was a 100 mm scale with 0= 'no craving' on the left end and 100= 'strongest craving ever' on the right end of the scale. Participants marked where along the scale reflected their craving for opioids. The full range of the change from baseline scale was therefore 100 (no craving at baseline, strongest craving during study) to -100 (strongest craving at baseline, no craving during study). Baseline was defined as the last non-missing value prior to subcutaneous injection on Day 1. The opioid craving VAS was completed each week; measurements were taken prior to dosing on weeks 5, 9, 13, 17 and 21. Negative change from baseline values indicate a lessening of craving symptoms. Change from baseline was analyzed using a mixed model for repeated measures (MMRM) with terms for treatment, visit, and treatment-by-visit interaction as factors and baseline value as a covariate. Center was included in the model as a random effect.

Population: Full analysis set of participants who had available data on baseline score and change from baseline in any visit through week 24.

The CGI-I was used to rate the change in clinical status since the start of the treatment on an ordinal scale ranging from 1 (very much improved; nearly all better; good level of functioning; minimal symptoms; represents a very substantial change) to 7 (very much worse; severe exacerbation of symptoms and loss of functioning). Baseline was defined as the last non-missing value prior to subcutaneous injection on Day 1. Measurements taken during the treatment period were taken at the end of each 28 day treatment and prior to dosing of the next treatment. Negative change from baseline values indicate an improved clinical global impression. Change from baseline was analyzed using a mixed model for repeated measures (MMRM) with terms for treatment, visit, and treatment-by-visit interaction as factors and baseline value as a covariate.

The CGI-S was an assessment completed by the clinician to rate the severity of symptoms on an ordinal scale ranging from 1 (normal, not at all ill) to 7 (among the most extremely ill subjects; pathology drastically interferes in many life functions). Baseline was defined as the last non-missing value prior to subcutaneous injection on Day 1. Measurements taken during the treatment period were taken at the end of each 28 day treatment and prior to dosing of the next treatment. Negative change from baseline values indicate an improvement in the severity of symptoms.

COWS is an 11-item instrument used to assess signs and symptoms of opioid withdrawal (Wesson et al., 1999). The score is the sum of the responses for a total range of 0-48. The COWS is commonly used by clinicians treating patients with buprenorphine to monitor the severity of withdrawal. COWS scores below 5 are considered not indicative of withdrawal. Scores from 5 to 12 are considered mild withdrawal; from 13 to 24 moderate withdrawal; 25 to 36 moderately severe withdrawal, and 37-48 severe withdrawal. Negative change from baseline values indicate a lessening of withdrawal symptoms. Baseline was defined as the last non-missing value prior to subcutaneous injection on Day 1. The COWS was completed each week; measurements were taken prior to dosing on weeks 5, 9, 13, 17 and 21. Change from baseline was analyzed using a mixed model for repeated measures (MMRM) with terms for treatment, visit, and treatment-by-visit interaction as factors and baseline value as a covariate.

Injection site pain as measured by participant-reported VAS The participant-reported VAS for injection site pain was measured on a 100 mm scale with 'no pain' on the left end and 'strongest pain ever' on the right end of the scale (total scale of 0-100). Participants marked where along the scale reflected their localized injection pain. The injection site pain VAS scores were obtained (after the completion of the injection) within 1 minute and at 5, 10, 15, 30, 60 and 120 minutes (+- 5 minutes). The timing of the injection site pain VAS should have been measured from the end of the injection. Data represents the worst pain recorded for each participant across all 6 injections and all VAS records. The mean value is presented.

These participants were given six volume-matched placebo injections on Days 1 to 141 with injections separated by 28 days. As of protocol Amendment 2 (21 August 2015) SUBOXONE sublingual film use was tapered from 6 mg to 2 mg from Days 1-5 and then discontinued. In addition, participants received individual drug counseling (IDC) at least once a week.
