Further study details as provided by Biotie Therapies Inc.:

Primary Outcome Measures:
  • Determine the safety of treatment with SYN117 in cocaine-dependent volunteers by measuring hemodynamic and subjective effects of administration of ascending doses of cocaine(10mg, 20mg, 40mg)and placebo during treatment with ascending doses of SYN117. [ Time Frame: inpatient 14 days with 2 week outpatient follow-up ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Determine tolerability by measuring adverse events [ Time Frame: inpatient 14 days, 2 weeks post followup visit ] [ Designated as safety issue: No ]
  • Determine subjective effects produced by self administration of cocaine or placebo [ Time Frame: Days 4, 8, 12 and 13 ] [ Designated as safety issue: No ]
  • Determine the effect of SYN117 of the pharmacokinetics of IV cocaine [ Time Frame: Days 3 and 11 ] [ Designated as safety issue: No ]
  • Determine if any baseline measures of impulsivity or drug use severity predict efficacy of SYN117 in reducing subjective effects of cocaine [ Time Frame: Days 4, 8 and 12 ] [ Designated as safety issue: No ]

Enrollment: 20
