Effectiveness of Extended Treatments for Drug Dependence
NCT00685659 · View on ClinicalTrials.gov ↗
Study Summary
This study tests the effectiveness of two 24 month, telephone-based adaptive continuing care interventions for patients with cocaine dependence. The two interventions are predicted to produce better drug use outcomes than standard care. Furthermore, the intervention that also includes monetary incentives for continued participation is hypothesized to produce better retention and drug use outcomes than the intervention without incentives. Economic analyses will determine the cost-effectiveness and benefit-cost of the interventions relative to standard care, and to each other.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00685659
The ClinicalTrials.gov registry entry for NCT00685659 describes a study currently listed as completed. It is categorized as NA, 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 332 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of Pennsylvania, which has 1,457 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Cocaine Dependence appearing as the primary indexed condition, and to 3 interventions — of which Intensive Outpatient Treatment 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: NCT00685659 reports 2 study locations spanning 1 distinct geographic area — top geographies include Pennsylvania. 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.
