- Proportion of Cocaine Use Days [ Time Frame: Day 1 up to day 98 ]The cocaine consumption was recorded once daily (Yes/No) by the subject using the Timeline Follow-Back (TLFB) cocaine assessment tool during the treatment period. For each patient, the proportion of cocaine use days was calculated by dividing the number of days of cocaine use during the treatment period, i.e. 98 days for completers and number of days between Day 1 and day of last dose in case of premature discontinuation of study treatment.
- Proportion of Positive Urine Measurements of Benzoylecgonine (BE) [ Time Frame: Day 1 up to day 98 ]Urine samples were analyzed for the presence of cocaine's metabolite benzoylecgonine (BE) which is the main metabolite of cocaine present in urine. Two urine samples were provided per week to provide a quantitative measure.
- Proportion of Days of Alcohol Consumption [ Time Frame: Day 1 up to day 98 ]Alcohol consumption was recorded by the subjects using the Timeline Follow-Back (TLFB) alcohol self report. The number of standard drinks were recorded daily. The proportion of days of alcohol consumption during the study treatment period was was compared using an ANCOVA model with treatment as factor and past alcohol consumption as covariate. The past consumption of alcohol was the proportion of alcohol over the 28 days preceding the screening visit, which was assessed retrospectively using the TLFB.
- AFQ056 Plasma Concentrations [ Time Frame: Day 15 (0h, 2h), Day 29 (0, 2h), Day 57 (0h, 2h), Day 98 (0h,2h) ]Plasma samples were collected to assess pharmacokinetics (PK)
