About this study

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 purpose of this study is to assess the safety and tolerability of ALKS33-BUP when administered to opioid-experienced cocaine abusers.

Read the detailed description

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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The primary outcome measures are safety and pharmacokinetics (PK)/ pharmacodynamics (PD)

    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.

    Measured: Study drug will be administered once daily for 10 consecutive days.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing ALKS 33-BUP and ALKS 33 in people with Cocaine Abuse, run by Alkermes, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 9 inclusion and 12 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 9 Mar 2012. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The primary outcome measures are safety and pharmacokinetics (PK)/ pharmacodynamics (PD) (time frame: Study drug will be administered once daily for 10 consecutive days.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 9 Mar 2012.
