ALK33BUP-101: Safety and Pharmacodynamic Effects of ALKS 33-BUP Administered Alone and When Co-administered With Cocaine
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
|Official Title:||A Phase 1, Multiple-dose, Parallel Group Study to Evaluate the Safety and Pharmacodynamic Effects of RDC-0313-buprenorphine (ALKS 33-BUP) Administered Alone and Co-administered With Cocaine to Opioid-experienced Cocaine Abusers|
- The primary outcome measures are safety and pharmacokinetics (PK)/ pharmacodynamics (PD) [ Time Frame: Study drug will be administered once daily for 10 consecutive days. ]For safety, the primary outcome measures are AEs and cardiovascular responses (Heart Rate, Blood Pressure, Electrocardiogram) collected during cocaine infusions at baseline and during treatment with ALKS 33-BUP, ALKS 33 and placebo.

There are no currently available pharmacologic treatments for cocaine abuse and/or dependence and the unmet medical need is growing. In collaboration with the National Institute on Drug Abuse (NIDA), Alkermes, Inc. is investigating a fixed-dose combination product consisting of ALKS 33 (also referred to as RDC-0313) and buprenorphine (ALKS 33-BUP) for the treatment of cocaine abuse and/or dependence (Grant Number R01DA031000).
This is a randomized, double-blind, placebo-controlled, parallel design inpatient study. Eligibility will be established which includes responses to cocaine infusions at baseline, prior to study drug administration. Approximately 30 opioid-experienced cocaine abusers will be randomized 1:1:1 to receive study drug. Study drug will be administered once daily for 10 consecutive days. Pharmacodynamic assessments and drug-drug interactions will be closely monitored during the study. Following study drug administration, subjects will receive cocaine infusions to evaluate the effect of treatment on the subjective effects and the PK/PD of cocaine. Subjects will be discharged from the clinical research unit 2 days after the last infusion of cocaine. Subjects will return for follow-up between 7 and 14 days after discharge. The full study will take subjects approximately 28 days, with 17 days of inpatient stay.
