Adverse events — posted to ClinicalTrials.gov
Time frame: Up To 24 Days.
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
This study will assess the safety, tolerability and blood concentrations of lasmiditan and topiramate together compared to lasmiditan and topiramate separately. Information about any side effects that may occur will be collected.
Participants will be admitted to the Clinical Research Unit (CRU) one day prior to the start of the study and will remain through Day 14.
This study is expected to last approximately 25 days, not including screening. Screening is required within 28 days prior to the start of the study.
