The purpose of this clinical trial is to learn about the pharmacokinetics and safety of a drug called zavegepant from samples collected using a patient-centric device called Tasso-Plus (for liquid blood sample collection) and Tasso-M20 (for dried blood sample collection) compared to standard venous sample collection. 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.
