Effects of Gabapentin Versus Placebo on Buprenorphine Detoxification of Opioid-dependent Individuals (Detox)

June 19, 2013 updated by: University of Arkansas
This study involves inducting treatment seeking opioid dependent participants onto buprenorphine. Once the participant reaches a stable dose they will receive either placebo or gabapentin to determine if gabapentin helps ease withdrawal symptoms while the participant undergoes a 10-day buprenorphine detoxification.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Availability to attend clinic 6 days a week for approximately 30-60 minutes.
  • Participants must fulfill DSM-IV criteria for opioid dependence. These criteria will be ascertained in the following manner: the physician will determine whether the individual is appropriate based on several clinical assessments that are routinely employed by methadone program physicians, including history and severity of opioid use, presence of track marks, prior treatment history, self-reported and/or observed signs and symptoms of opioid withdrawal. If any individual's degree of opioid dependence is questionable, that person will be excluded from further consideration as a participant.
  • Participants must submit a urine negative for drugs of abuse other than opioids prior to starting the study.

Exclusion Criteria:

  • Unstable medical condition or stable medical condition that would interact with study medications or participation.
  • History of major psychiatric disorder (psychosis, schizophrenia, bipolar, depression)
  • Pregnancy or plans to become pregnant or inadequate birth control (adequate birth control includes abstinence, condoms, birth control pills, etc).
  • Present or recent use of over-the-counter psychoactive drug, prescription psychoactive drug or drug (including Maalox) that would have major interaction with drugs to be tested.
  • Liver function tests greater than 3 times normal, BUN and Creatinine outside normal range, or thyroid function tests outside normal range.
  • EKG abnormalities including but not limited to: bradycardia (<60 bpm); prolonged QTc interval (>450 msec); Wolff-Parkinson White syndrome; wide complex tachycardia; 2nd degree, Mobitz type II heart block; 3rd degree heart block; left or right bundle branch block.
  • Physical dependence on alcohol or drugs other than opioids or tobacco (as determined by physician assessment).

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available.

ACTIVE_COMPARATOR: Gabapentin
Buprenorphine will be given along with 2 capsules of gabapentin in the morning and 2 take-home capsules of gabapentin for night.
Drug: Buprenorphine
Induction onto buprenorphine to a stable dose of 12mg/day. Then induction onto either 0 or 1600mg of gabapentin. Once the maintenance dose of gabapentin is reached a 10-day buprenorphine detoxification will begin.
