About this study

Official title: A Double-Blind, Placebo-Controlled Study of Modafinil for Cocaine Dependence

Despite years of active research, there are still no approved medications for the treatment of cocaine dependence. The purpose of this study is to determine the effectiveness of modafinil in treating cocaine-dependent individuals.

Read the detailed description

Modafinil is a glutamate-enhancing agent that blunts cocaine euphoria under controlled conditions. Due to its stimulant-like properties, modafinil is also likely to relieve severe cocaine withdrawal symptoms. In turn, this may lead to better clinical outcomes. The purpose of this study is to determine whether modafinil improves abstinence during early recovery from cocaine dependence.

This 6-month, double-blind, placebo-controlled trial will enroll 210 participants with current DSM-IV diagnoses of cocaine dependence. Treatment will occur for 8 weeks. Participants will be randomly assigned to receive a single morning dose of low-dose modafinil (200 mg/day), high-dose modafinil (400 mg/day), or matching placebo tablets. In addition, each week participants will receive manual-guided cognitive behavioral therapy at the Treatment Research Center. At the end of the 8-week treatment period, modafinil or placebo will be abruptly discontinued. One week following, an end of medication evaluation will occur. In addition to this, two follow-up evaluations will take place 3 and 5 months after initial randomization. Efforts will be made to continue evaluation of subjects who decide to discontinue the modafinil treatment. Urine benzoylecgonine levels will be used to measure cocaine abstinence. Craving, withdrawal, retention, and adverse events will also be evaluated.

What is being measured

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

  1. Urine Toxicology for Cocaine

    Abstinent in the final 3 weeks of treatment

    Measured: 3 weeks

Secondary outcomes (2)
  1. Retention; Number of Evaluation Visits Attended

    Number of visits attended compared between the three conditions using anova

    Measured: 8 weeks

  2. Cocaine Selective Severity Assessment (CSSA) Total Score

    Cocaine Selective Severity assessment (CSSA) total score has a range 0-126. Higher scores indicating greater severity of cocaine withdrawal obtained weekly. Groups compared using GEE model over 8 weeks of treatment.

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Low Dose Modafinil and High Dose Modafinil in people with Cocaine-Related Disorders, run by University of Pennsylvania 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 5 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 8 May 2018. 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 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?

Yes. Results are posted in the registry (first posted 8 May 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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 (time frame: 3 weeks). 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 8 May 2018.
