Status Recruiting

Clinical Trial Summary

The goal of this clinical trial is to learn if administering a high dose stimulant with Contingency Management reduces days of use in adults who use methamphetamine better than the usual treatment provided by the clinic. The main questions the trial aims to answer are: Is a high dose stimulant better than a placebo and usual treatment at helping reduce the number of days they use methamphetamine? Is a high dose stimulant with contingency management better than placebo and usual treatment at helping people reduce the number of days they use methamphetamine? Participants will be placed randomly into one of four groups: 1. Usual treatment and placebo 2. Usual treatment, placebo and contingency management 3. Usual treatment and high dose stimulant 4. Usual treatment, high dose stimulant and contingency management Participation includes the following: 1. Participants will receive medication or placebo weekly for 15 weeks. 2. Participants will attend the clinic for weekly treatment 3. Participants will attend the clinic once every 2 weeks for study visits. Each visit will take about an hour to complete. At these visits, participants will be asked to provide a urine sample and complete questionnaires.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
