Study of Oral Lasmiditan in Participants With Normal and Impaired Renal Function

Study Overview
=================
Brief Summary
-----------------
This is a multi-center, open-label, non-randomized, parallel-group, adaptive, single dose study. This study will enroll up to 32 participants using an adaptive design that can include up to 3 groups of 8 participants with different degree of renal impairment and one group of 8 control participants with normal renal function. Screening data will be reviewed to determine participant eligibility. Participants who meet all inclusion criteria and none of the exclusion criteria will be entered in the study. First, approximately 16 participants will be enrolled with severe renal impairment and matched participants with normal renal function. There will be 8 participants in each of the following groups based on renal function at screening: Group 1: Healthy participants with normal renal function (estimated glomerular filtration rate [eGFR] ≥ 90 milliliters per minute per 1.73 meters squared [mL/min/1.73m²]) Group 2: Severe renal impairment participants (eGFR < 30 mL/min/1.73m²) Based on safety and pharmacokinetic (PK) results from participants with severe renal impairment (Group 2), Group 3 (Moderate Renal Impairment) and Group 4 (Mild Renal Impairment) will be enrolled if substantial change in the exposure of lasmiditan is observed in participants with severe renal impairment.

If the investigator concludes that there is no safety risk for participants with isolated laboratory abnormalities (eg, those that do not reflect end-organ dysfunction; for example, elevated bilirubin in Gilbert's participants) to participate in the study, such cases need to be discussed and approved by the sponsor's medical monitor prior to study enrollment Presence of clinically significant physical, laboratory, or ECG finding that, in the opinion of the Investigator and/or sponsor, may interfere with any aspect of study conduct or interpretation of results Participants with acute, unstable, or untreated significant medical conditions. Participants requiring treatment for renal impairment or other chronic disease (eg, well-controlled diabetes, hypertension) must be on a stable treatment plan (medicines, doses, and regimens) for at least 2 weeks (except insulin) prior to Day 1 and during the entire study. Small adjustments in the dosages of some concomitant medications may be permitted during the study, and will be discussed on a case-by-case basis. In all cases, the participants' treatment history must be reviewed and their enrollment must be agreed to by both the investigator and the sponsor's medical monitor Positive screening of alcohol and/or drugs of abuse unless results can be explained by a prescription medication Concurrent use of medications known to affect the elimination of serum creatinine (eg, trimethoprim/sulfamethoxazole [Bactrim®] or cimetidine [Tagamet®]) and competitors of renal tubular secretion (eg, probenecid) within 30 days prior to the first dose of study drug or anticipated need for these therapies through the last pharmacokinetic (PK) sample
