Interventions: intervention 1: MK-1602 intervention 2: Placebo intervention 3: Rescue medication
Intervention descriptions: intervention 1: Three administrations of the same dose of MK-1602 on separate days. All 3 doses are either 1, 10, 25, 50 or 100 mg of MK-1602. Dose 1: Taken at onset of migraine of moderate or severe intensity. Dose 2: Taken the evening before Visit 2. Dose 3: Taken at Visit 2, which is Day 4 post migraine treatment (Dose 1).

Dosage form is film coated tablet for oral administration. intervention 2: Three administrations of placebo for MK-1602 on separate days. Dose 1: Taken at onset of migraine of moderate or severe intensity. Dose 2: Taken the evening before Visit 2. Dose 3: Taken at Visit 2, which is Day 4 post migraine treatment (Dose 1).

Dosage form is film coated tablet for oral administration. intervention 3: If moderate or severe migraine headache pain continues 2 hours after dose of study medication or if migraine headache comes back within 48 hours,

Participants will be allowed to take their own rescue migraine medication, which may include analgesics (e.g., nonsteroidal anti-inflammatory drugs \[NSAIDs\]), anti-emetics, triptans, opiates or other medication not explicitly excluded.
