Summary

This is a double-blind, placebo-controlled, parallel group study to compare the effects of STP7 (mavoglurant) vs placebo control on i.v. cocaine's physiological and subjective effects in non-treatment seeking, cocaine-experienced males or females participants between 18 and 59 years of age. The primary objective of this study is to determine if there are clinically meaningful interactions between oral STP7 (mavoglurant) treatment concurrent with 20 and 40 mg i.v. cocaine infusions by measuring adverse events and cardiovascular responses including heart rate, blood pressure, and electrocardiogram (including corrected QT interval). The secondary objectives are: * To evaluate whether administration of STP7 (mavoglurant) alters the pharmacokinetics of cocaine and/or its major metabolite, benzoylecgonine. * To determine the pharmacokinetic of STP7 (mavoglurant) administered at a dose of 200 mg twice a day. * To evaluate whether STP7 (mavoglurant) treatment alters the subjective effects of cocaine measured by Visual Analog Scales (VAS) and Brief Substance Craving Scale (BSCS).
