Brief summary

This will be a randomized, single dose, double-blind, placebo-controlled, Latin-square design with 5-period (full) crossover study with participants randomized to treatment sequences. Participants will complete all 5 Periods. During each Period, participants will come to the clinical research unit (CRU) and remain overnight before being dosed with a single dose of either lasmiditan, alprazolam, or placebo in the morning. Cognitive testing and driving simulation will be conducted post dosing. Participants will have a washout of at least 5 days between each Period. This study is designed to test non-inferiority of lasmiditan doses relative to placebo, with an alprazolam test versus placebo to confirm the sensitivity of the simulator to detect treatment effects.

Simulated Driving Performance in Healthy Participants as Measured by Standard Deviation of Lateral Position (SDLP) Using the Cognitive Research Corporation Driving Simulator-MiniSim (CRCDS-MiniSim)Approximately 90 minutes post dose, on Day 1, 7, 14, 21, or 28 depending upon the assigned treatment sequenceThe standard deviation of lateral position (SDLP) is the primary parameter used as stable measure of driving performance with high test-retest reliability. It measures the driver's ability to stay in a constant position within the driving lane. Variations in the lateral position are recorded and analyzed. SDLP, was analyzed using a mixed model with fixed effects for sequence, period, and treatment, and a random effect for participant within sequence. A variance component covariance structure and Kenward-Roger degrees of freedom was used.

Secondary

MeasureTime frameDescription
Karolinska Sleepiness Scale (KSS) ScoreApproximately 85 minutes post dose, on Day 1, 7, 14, 21, or 28 depending upon the assigned treatment sequenceThe KSS is used to assess subjective level of sleepiness. This is a participant self-report measure of situational sleepiness and provides an assessment of alertness/sleepiness at a particular point in time. It is a 9-point categorical Likert scale on which the participant rates sleepiness from 1 (very alert) to 9 (very sleepy/fighting sleep), with higher scores indicating more sleepiness and lower scores indicating more alertness.
Percentage of Participants With Self-Reported Readiness to DriveApproximately 85 minutes post dose, on Day 1, 7, 14, 21, or 28 depending upon the assigned treatment sequenceOn each dosing day participants were asked Right now do you feel safe to drive?. Pair-wise comparisons for readiness to drive were analyzed using McNemar test.
Motivational and Self-Appraisal Visual Analog Scale (VAS)Approximately 2.5 hours post dose, on Day 1, 7, 14, 21, or 28 depending upon the assigned treatment sequenceAfter completing the driving simulation, participants assessed their own performance and their level of motivation to perform at their best during the driving simulation. Participants responded to 2 questions: 1. How well do you think you drove for the last 60 minutes? 2. How motivated did you feel to drive at your best during the last 60 minutes of driving?. Participants recorded their response to each question by writing a vertical line on a 100 millimeters (mm) horizontal, linear visual analog scale indicating their level of performance (Not Satisfactory to Satisfactory) and motivation (Not Motivated to Motivated). Scores on the 100 mm linear scale were measured to the nearest millimeter from the left. Scores ranged from 0-100 mm, with higher scores indicating motivated and satisfactory and lower scores indicating not motivated and not satisfactory.
Driving Performance Using the CRCDS-MiniSim - Lane ExceedanceApproximately 90 minutes post dose, on Day 1, 7, 14, 21, or 28 depending upon the assigned treatment sequenceThe CRCDS-MiniSim is a PC-based research driving simulator that provides a realistic automotive driving environment. The present study employs the Country Vigilance-Divided Attention (CVDA) driving scenario, a 62.1 mile (100 km), monotonous, two lane highway driving task that includes a secondary visual vigilance task (DA). The monotonous Country Vigilance scenario has been demonstrated to be sensitive to detect the effects of fatigue or sleepiness on driving performance. Lane exceedance is the number of lane exceedances, an indication of lane position control, (i.e., the driver's ability to stay within his/her lane), as measured by the number of times that the front left or right tire of the vehicle crosses over the right or left lane boundary.
Driving Performance Using the CRCDS-MiniSim - Speed DeviationApproximately 90 minutes post dose, on Day 1, 7, 14, 21, or 28 depending upon the assigned treatment sequenceThe CRCDS-MiniSim is a PC-based research driving simulator that provides a realistic automotive driving environment. The present study employs the Country Vigilance-Divided Attention (CVDA) driving scenario, a 62.1 mile (100 km), monotonous, two lane highway driving task that includes a secondary visual vigilance task (DA). The monotonous Country Vigilance scenario has been demonstrated to be sensitive to detect the effects of fatigue or sleepiness on driving performance. Speed deviation is a measure of intra-individual variability. Measures that assess an individual's failure to maintain consistent performance are more sensitive to sedation than are measures of absolute performance.
Number of Correct Responses in Driving Performance Using CogScreen Symbol Digit Coding (SDC) TestApproximately 85 minutes post dose, on Day 1, 7, 14, 21, or 28 depending upon the assigned treatment sequenceThe SDC Test, a digit symbol substitution test that is sensitive to changes in information processing speed, provides measures of response speed and accuracy. The test was administered prior to the simulated driving sessions. The principal test score measures the number of correct responses in 120 seconds. SDC was used in this study to measure attention, visual scanning, working memory, and speed of information processing. Scores range from 0 (No correct responses). A higher score indicates greater processing speed.

Participants recorded their response to each question by writing a vertical line on a 100 millimeters (mm) horizontal, linear visual analog scale indicating their level of performance (Not Satisfactory to Satisfactory) and motivation (Not Motivated to Motivated). Scores on the 100 mm linear scale were measured to the nearest millimeter from the left. Scores ranged from 0-100 mm, with higher scores indicating motivated and satisfactory and lower scores indicating not motivated and not satisfactory.

Time frame: Approximately 2.5 hours post dose, on Day 1, 7, 14, 21, or 28 depending upon the assigned treatment sequence

Population: All randomized participants who received study drug and have evaluable data for visual analog scale.

Number of Correct Responses in Driving Performance Using CogScreen Symbol Digit Coding (SDC) Test

The SDC Test, a digit symbol substitution test that is sensitive to changes in information processing speed, provides measures of response speed and accuracy. The test was administered prior to the simulated driving sessions. The principal test score measures the number of correct responses in 120 seconds. SDC was used in this study to measure attention, visual scanning, working memory, and speed of information processing. Scores range from 0 (No correct responses). A higher score indicates greater processing speed.

Time frame: Approximately 85 minutes post dose, on Day 1, 7, 14, 21, or 28 depending upon the assigned treatment sequence

Population: All randomized participants who received study drug and have evaluable data for driving performance.
