A Study to Learn About the Study Medication, Zavegepant, in Healthy Volunteers

This is a Phase 1, single centre, open-label, single dose, 4-period, crossover study designed to compare the pharmacokinetics (PK) of zavegepant from three Test products and a Reference product (treatment D). 52 male and female healthy volunteers will be randomly assigned to one of 4 treatment sequences: ACBD, CDAB, BADC, and DBCA. In each period, subjects will receive one of the following: Treatment A, B, C, or D on Day 1, followed by 24 hours of PK and safety assessments. On Day 2 subjects will be discharged from the clinical site and instructed to return after at least a 7 day washout time has passed for subsequent periods of treatment. The study will include a screening visit from Day -28 to Day -2. Eligible subjects will be admitted to the clinical site on Day -1 and will be confined until completion of the assessments on Day 2. There will be a washout period of at least 7 days between doses. Study Exit procedures will be performed after the last assessment on the morning of Day 2 of Period 4. Study Exit procedures will be performed as soon as possible in case of Early Termination. The total duration of study participation for each subject from Screening through Study Exit is anticipated to be approximately 6.5 weeks.
