Treatment of Heroin and Cocaine With Methadone Maintenance and Contingency Management
NCT00292110 · View on ClinicalTrials.gov ↗
Study Summary
Background: \- The treatment of addiction often hinges on preventing relapse into drug-using behaviors, which occurs at high rates even after prolonged abstinence. Some methadone patients continue to abuse cocaine and heroin during treatment, even with extensive psychosocial services. More research is needed to look at the results from earlier studies of continued drug use during methadone treatment, focusing on the results of fixed vs. flexible doses of methadone to reduce the likelihood of continued drug use and the role of monetary vouchers as an incentive to continue abstinence from illicit substances. Objectives: \- To determine if the combination of flexible methadone dosing and voucher-based contingency management can improve rates of abstinence from heroin and cocaine. Eligibility: \- Individuals between 18 and 65 years of age or older who are dependent on opioids (cocaine and/or heroin). Design: * The study will last 40 weeks. After the initial screening, participants will receive daily methadone and weekly drug counseling sessions that will continue throughout the study. * After 6 weeks of methadone treatment, participants who continue to use heroin and cocaine will be randomized to one of four groups for 16 weeks of study. Each group will receive a flexible or fixed dose of methadone, and one of two contingency management conditions. * Flexible-dose participants will receive individualized dose increases, based on drug use and withdrawal. Fixed-dose participants will be set at a specific dose of methadone that will not be changed. * The two contingency management conditions will be monetary vouchers given for regular cocaine-negative urine samples, or vouchers independent of urine cocaine screen results. * After the study phase, participants will have 10 weeks of standard individual counseling and stable doses of methadone. Urine samples will continue to be collected, but no vouchers will be given. * At the end of the study, participants will have

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00292110
The ClinicalTrials.gov registry entry for NCT00292110 describes a study currently listed as completed. It is categorized as Phase 1, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 140 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute on Drug Abuse (NIDA), which has 108 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 2 conditions, with Cocaine-Related Disorders appearing as the primary indexed condition, and to 4 interventions — of which Methadone is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00292110 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
