Clinical Trial Summary

The main purpose of this study is to determine the outcome of a drug combination treatment on detoxified and stabilized methamphetamine (METH) and/or cocaine (COC) dependent users. The combination regimen consists of oral administration of a generic immediate-release methylphenidate (MPh-IR) formulation (e.g., Ritalin®) and a novel delayed, pulsatile-release formulation of the antiemetic ondansetron (Ond-PR002). Various psychological assessment tools and functional magnetic resonance imaging (fMRI) will be used to assess the treatment outcome. In addition to the treatment outcome measures, we will determine whether the 14-day, once-a-day treatment leads to significant changes in the pharmacokinetic/pharmacodynamic (PK/PD), safety and tolerability parameters of MPh-IR and/or Ond-PR002 formulations and drug-drug interactions between the two drugs.
