Description of intervention(s) / exposure
Treatment: Other - MK-1200
Treatment: Drugs - Antiemetic

Experimental: Part 1: MK-1200 - In Part 1, participants will receive escalating doses of MK-1200 via intravenous (IV) infusion every 2 weeks (Q2W) until any discontinuation criteria are met.

Experimental: Part 2: MK-1200 Cohort A - In Part 2, participants in Cohort A will receive either Dose 1 or Dose 2 of MK-1200 via IV infusion Q2W until any discontinuation criteria are met.

Experimental: Part 2: MK-1200 Cohort B - In Part 2, participants in Cohort B will receive Dose 1 of MK-1200 via IV infusion Q2W until any discontinuation criteria are met.


Treatment: Other: MK-1200
IV Infusion

Treatment: Drugs: Antiemetic
One or more prophylactic antiemetic(s) (e.g. 5-HT3 receptor antagonists, dexamethasone, neurokinin-1 receptor antagonists, etc.) may be selected based on previous response of participants to antiemetic medications and individual factors, and will be administered per approved product label prior to MK-1200 infusion
