Official title:
A Randomized, Subject- and Investigator-Blind, Placebo and Active-Controlled Study to Assess the Abuse Potential of Lasmiditan

Study type | Interventional |
The purpose of this study is to assess the abuse potential of study drug lasmiditan.
Lasmiditan will be compared to a marketed benzodiazepine, alprazolam (positive control), as
well as to placebo (dummy substance that looks like lasmiditan or alprazolam without any
active drug) to determine the potential for drug abuse. The dosages will be in tablet form
and will be taken orally (by mouth).
This study will last about 55 days, including screening. Screening will occur within 28 days
prior to qualification phase.

Primary | Pharmacodynamics (PD): Maximal Effect Score (Emax) of Bipolar Drug Liking Visual Analog Scale (VAS) Scores | The Emax of Bipolar Drug Liking VAS Scores were derived as the maximum at-the-moment Drug Liking VAS score where the time to Emax was the corresponding time point at which the maximum score occurred. The bipolar Drug Liking VAS is consistent with FDA Guidance (January 2017) such that placebo should produce a score between 40 and 60 representing neutral drug-liking (ie, neither like nor dislike); a score ranging from 0 to 100 and a score of 0 indicates strong disliking, and a score of 100 indicates strong liking. Least squares mean (LS mean) was calculated using a linear mixed-effects model, including period, sequence, and treatment as fixed effects, and subject as a random effect, was used to evaluate the hypothesis tests of primary interest (at-the-moment Drug Liking) at the Emax. | Each Phase: 24 Hours | |
Secondary | Pharmacokinetics (PK): Maximum Observed Drug Concentration (Cmax) of Lasmiditan | Pharmacokinetics (PK) defined as the maximum observed drug concentration (Cmax) of lasmiditan | Predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24 hours Post Dose | |
Secondary | PK: Area Under the Curve of Lasmiditan From Zero to Infinity (AUC[0-8]) | PK defined as the area under the curve of lasmiditan from zero to infinity (AUC[0-8]) | Predose, 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 8, 12, 24 hours Post Dose | |
Secondary | PD: Maximal Drug Effects (Emax) Visual Analog Scale (VAS) | Drug Effects VAS Battery lists a series of measures that evaluate different effects of the abuse potential of the study drug. Scales include: Overall drug liking (overall, my liking for this drug is) and ranges from 0 definitely not to 100 definitely so. Take Drug Again (I would take this drug again) and ranges from 0 definitely not to 100 definitely so. Good effects (I can feel good drug effects) and ranges from 0 definitely not to 100 definitely so. Bad effects (I can feel bad drug effects) and ranges from 0 definitely not to 100 definitely so. High (I am feeling) and ranges from 0 not at all high to 100 extremely high. Emax is derived as the maximum score across all postdose time points for each participant. Least Square (LS) Mean is calculated using the linear mixed-effects model with period, sequence and treatment as fixed effects and participant as a random effect. | Each Phase: Predose, 0.25, 0.5, 1, 1.5, 2, 2.5,3, 3.5, 4, 4.5, 5, 6, 8, 12, 24 Hours Post Dose | |
Secondary | PD: Maximal Drug Effects (Emax) VAS (Hallucinations) | Drug Effects VAS Battery lists a series of measures that evaluate different effects of the abuse potential of the study drug. The hallucinations scale is presented meaning (I am hallucinating) and ranges from 0 not at all to 100 extremely. Emax is derived as the maximum score across all postdose time points for each participant. Median and interquartile range are reported for each treatment group. | Each Phase: Predose, 0.25, 0.5, 1, 1.5, 2, 2.5,3, 3.5, 4, 4.5, 5, 6, 8, 12, 24 Hours Post Dose | |
Secondary | PD: Minimum Drug Effects (Emin) Visual Analog Scale (VAS) | Drug Effects VAS Battery lists a series of measures that evaluate different effects of the abuse potential of the study drug. The scales included: Alertness/Drowsiness (I am feeling) ranges from 0 very drowsy to 100 very alert. Agitation/Relaxation (my mood is) and ranges from 0 very relaxed to 100 very agitated. Emin is derived across all postdose time points for each participant. LS Mean was calculated using the linear mixed-effects model with period, sequence and treatment as fixed effects and participant as a random effect. | Each Phase:Predose, 0.25, 0.5, 1, 1.5, 2, 2.5,3, 3.5, 4, 4.5, 5, 6, 8, 12, 24 Hours Post Dose | |
Secondary | PD: Mean Scores on Drug Similarity VAS Measures | Participants marked a point on a 100-mm horizontal line that best represented their response to the given question. The endpoints of each electronic scale were marked with descriptive anchors on a scale from 0 to 100 (Fraser et al. 1961; Bond and Lader 1974; Bigelow 1991; Shram et al. 2010). In the "How similar" questions, ranges from 0 to 100 and a score of 0 indicates definitely not similar, and a score of 100 indicates definitely similar. | Each Phase: 24 Hours Post Dose |
