This study consists of two periods and will enroll approximately 14 healthy participants. In period 1, half of the enrolled participants (n=7) will use Tasso-Plus, and the other 50% (n=7) will use Tasso-M20. For each participant, PK samples will be collected after zavegepant administration in period 1 using the assigned Tasso device simultaneously with collecting venous blood samples. In addition, taste assessments will be performed at time intervals of 1 (immediately after dosing), 5, 10 and 20 minutes after zavegepant IN administration. Also, if feasible, 4 Japanese participants will be enrolled among those 14 participants to evaluate the PK and safety of zavegepant IN in Japanese vs. non Japanese participants. In period 2, a butterscotch candy will be given 5 minutes before administering the zavegepant IN study intervention. Taste assessment will also be performed after zavegepant IN administration with a butterscotch candy in period 2. For taste assessment, each participant will record the sensory attributes at timed intervals of 1 (immediately after dosing), 5, 10 and 20 minutes after zavegepant administration in each period. The expected duration of participation from screening until follow-up telephone contact is approximately 9 weeks.
