- Adult
Who may be able to join
- One hundred forty male and female cocaine-abusing, opioid-dependent individuals between the ages 21-55, with at least 40% women and 40% Afro-Americans, who not be currently enrolled in treatment, will be entered into the study. Subjects must have current opioid dependence as evidenced by documentation of prior treatment for opioid dependence or signs of withdrawal upon administration of naloxone (0.8 mg, i.m.), and opioid-positive urine screen. Subjects also must be current users of cocaine with self-reported use of > 12 gms during the preceding 12 months, self-reported use of > 1 gm/week in the month preceding study entry, and cocaine-positive urine screen. Subjects must fulfill DSM-III-R criteria for opioid and cocaine dependence. These criteria will be ascertained using the substance abuse section of the SCID interview developed for use with DSM-III-R

About this study
Official title: LAAM With Behavioral Treatment for Opioid/Cocaine Abuse
Although LAAM, a derivative of methadone, has been successfully used as an alternative to methadone maintenance in opioid addicts, its effect on concurrent opioid and cocaine abuse has not been ascertained. Thus, this study proposes to examine the clinical efficacy of low- and high-dose LAAM maintenance on opioid and cocaine use in opioid-dependent cocaine abusers. In addition, since contingency management procedures have demonstrated some success in decreasing cocaine use in cocaine-abusing individuals, this study also proposes to examine the clinical efficacy of the presence or absence of contingency management procedures targeting illicit drug use.
Read the detailed description
One hundred forty male and female opioid-dependent cocaine abusers will be stratified by sex and randomly assigned to one of four treatment groups according to a 2 x 2 experimental design: low-dose LAAM (99 mg/wk) with adjunct contingency management procedures; low-dose LAAM (99 mg/wk) without adjunct contingency management procedures; high-dose LAAM (330 mg/wk) with adjunct contingency management procedures; and high-dose LAAM (330 mg/wk) without adjunct contingency management procedures. The duration of the study will be 24 weeks, with LAAM being administered on a thrice-weekly (MWF) basis.
Subjects are inducted onto LAAM during weeks 1-3 and then maintained on their assigned maintenance dose (99 mg/wk or 330 mg/wk) through week 24. During maintenance, the Friday dose will be 1.3 times greater than the Monday and Wednesday dose. At the conclusion of the study, subjects undergo detoxification from LAAM over a 4-week period. For those in the contingency management procedure group, each drug-free urine submitted will result in a voucher worth a certain monetary value that increases for consecutively drug-free urines (weeks 1-12) or a monetary voucher with a fixed value (weeks 13-24). Subjects not assigned to the contingency management procedure will receive monetary vouchers (weeks 1-24) according to a yoked-control schedule (that is, not contingent upon illicit drug abstinence). Vouchers can be exchanged for mutually agreed upon goods and services at any time during the study. Outcome measures will include: 1) treatment retention, 2) illicit drug use, 3) self-reported adverse and opioid withdrawal symptoms, and 4) psychosocial functioning. Follow-up interviews at nine months and/or one year post-study entry will be conducted to determine status post-treatment. Prognostic factors (i.e., sex, post-traumatic stress disorder, and depression), will also be examined in relation to treatment outcome and post-treatment status.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Although LAAM, a derivative of methadone, has been successfully used as an alternative to methadone maintenance in opioid addicts, its effect on concurrent opioid and cocaine abuse has not been ascertained. Thus, this study proposes to examine the clinical efficacy of low- and high-dose LAAM maintenance on opioid and cocaine use in opioid-dependent cocaine abusers. In addition, since contingency management procedures have demonstrated some success in decreasing cocaine use in cocaine-abusing individuals, this study also proposes to examine the clinical efficacy of the presence or absence of contingency management procedures targeting illicit drug use.

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 1 inclusion and 1 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 12 Jan 2017. 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. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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?
Urine toxicology for cocaine. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00158288, which also lists 1 linked publication.
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 12 Jan 2017.
