SUBLOCADE Rapid Initiation Study
An Open-label, Rapid Initiation Study for Extended-Release Buprenorphine Subcutaneous Injection (SUBLOCADE)
Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
Currently patients who are appropriate candidates for SUBLOCADE™ injection for subcutaneous (SC) use must initiate treatment with TM buprenorphine for a minimum of 7 days before receiving their first injection. This study is to evaluate the safety and tolerability of starting SUBLOCADE treatment following a shorter period.
Adults with moderate to severe opioid use disorder (OUD) not currently receiving medication assisted treatment will be recruited to participate. Prior to receiving TM buprenorphine, subjects will report their last opioid use and be experiencing at least mild withdrawal. Subjects will receive at least one dose of TM buprenorphine to ensure tolerability and that they show no evidence of precipitated withdrawal. If no evidence of intolerability or no precipitated withdrawal occurs, subjects will receive a single injection of SUBLOCADE and remain in the clinic for approximately 48 hours after the injection to assess for safety and tolerability.

Intervention / Treatment |
---|---|
Experimental: TM buprenorphine followed by SUBLOCADE 300 mg
Participants with a diagnosis of OUD stopped use of their current opioid prior to coming to the clinic to be assessed for withdrawal symptoms.
If confirmed to be in withdrawal, participants were administered 4 mg transmucosal (TM) buprenorphine.
If tolerated without sensitivity, clinical signs of sedation, or precipitated withdrawal, 300 mg SUBLOCADE was administered.
Following SUBLOCADE administration, participants remained in the clinic for approximately 48 hours and were assessed for safety and tolerability, as well as for any signs of precipitated withdrawal.
Participants returned to the clinic weekly, until the end-of-treatment (EOT) visit (28 days after SUBLOCADE administration).

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Participants Who Experienced Any Precipitated Withdrawal Within One Hour After SUBLOCADE Administration
Time Frame: Day 1: Pre-SUBLOCADE evaluation taken after TM buprenorphine treatment and prior to injection: SUBLOCADE evaluation taken within one hour of SUBLOCADE injection
|
Clinical Opiate Withdrawal Scale (COWS) is an 11-item instrument used to assess signs and symptoms of opioid withdrawal. 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. Precipitated withdrawal was defined as in increase in Clinical Opioid Withdrawal Scale (COWS) score by ≥6 from the pre-SUBLOCADE value within 1 hour SUBLOCADE injection. |
Day 1: Pre-SUBLOCADE evaluation taken after TM buprenorphine treatment and prior to injection: SUBLOCADE evaluation taken within one hour of SUBLOCADE injection

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Participants With Treatment-Emergent Adverse Events (TEAE)
Time Frame: Day 1 to Day 28
|
A TEAE was an AE that started after the administration of TM buprenorphine for induction on Day 1. TEAE=any untoward medical occurrence that develops or worsens in severity after dispensation of the study drug and does not necessarily have a causal relationship to the study drug. Severity was rated by the investigator as mild, moderate and severe, with severe= a marked limitation in activity. Relation of AE to treatment was determined by the investigator. Serious AEs include death, a life-threatening AE, inpatient hospitalization or prolongation of existing hospitalization, persistent or significant disability or incapacity, a congenital anomaly or birth defect, OR an important medical event that jeopardized the patient and required medical or surgical intervention to prevent one of the outcomes listed in this definition. AEs of special interest include SUBOCADE depot removal, occurrences of alanine aminotransferase (ALT) >3*upper limit of normal (ULN) and bilirubin >2*ULN. |
Day 1 to Day 28

Participants With Treatment-Emergent Adverse Events (TEAE) Within 48 Hours Post-SUBLOCADE Injection
Time Frame: Day 1 SUBLOCADE injection up to 48 hours later

Cumulative number of participants in key timepoints who had a COWS total score increase of ≥6 points from the pre-SUBLOCADE value. |
Day 1: Pre-SUBLOCADE evaluation taken after TM buprenorphine treatment and prior to injection: SUBLOCADE evaluations taken 1, 6, 12, 24 and 48 hours after SUBLOCADE injection.

COWS Total Score Normalized Area Under the Curve (AUC) Through Key Timepoints Post SUBLOCADE Injection
Time Frame: SUBLOCADE injection on Day 1 through 1, 6, 12, 24 and 48 hours after SUBLOCADE injection
|
The area under the curve (AUC) for COWS total score from the pre-SUBLOCADE value to a later time point were calculated using the linear trapezoidal method. For each analysis time interval (AUC0-1hr, AUC0-6hrs, AUC0-12hrs, AUC0-24hrs, AUC0-48hrs) the AUC value was normalized across participants for the actual duration (in hours) of the time interval. The normalized AUC for COWS can be interpreted as the averaged AUC per hour or the averaged COWS over a time interval, as if the COWS was measured hourly during that time interval. Participants were included in a given interval if they had a pre-SUBLOCADE COWS assessment and a COWS assessment at the terminal timepoint for the interval. |

Clinical Opiate Withdrawal Scale (COWS) is an 11-item instrument used to assess signs and symptoms of opioid withdrawal.
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.
