Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: 0.35 mg MK-5823 - Healthy Participants<br> | Drug: MK-5823<br>* MK-5823 administered subcutaneously (doses ranging from 0.35 mg to 2.8 mg) once daily for 3 weeks. Doses may be adjusted downward based on safety, tolerability, and/or pharmacokinetic data. The decision to dose escalate will be based on accrued safety/tolerability data at the prior dose level. In each arm, 6 participants will be randomized to receive study drug and 2 participants will be randomized to receive placebo.<br>Other: Placebo<br>* Matching placebo to MK-5823 administered subcutaneously once daily for 3 weeks.<br>|
| Experimental: 0.7 mg MK-5823 - Healthy Participants<br> | Drug: MK-5823<br>* MK-5823 administered subcutaneously (doses ranging from 0.35 mg to 2.8 mg) once daily for 3 weeks. Doses may be adjusted downward based on safety, tolerability, and/or pharmacokinetic data. The decision to dose escalate will be based on accrued safety/tolerability data at the prior dose level. In each arm, 6 participants will be randomized to receive study drug and 2 participants will be randomized to receive placebo.<br>Other: Placebo<br>* Matching placebo to MK-5823 administered subcutaneously once daily for 3 weeks.<br>|
| Experimental: 1.4 mg MK-5823 - Healthy Participants<br> | Drug: MK-5823<br>* MK-5823 administered subcutaneously (doses ranging from 0.35 mg to 2.8 mg) once daily for 3 weeks. Doses may be adjusted downward based on safety, tolerability, and/or pharmacokinetic data. The decision to dose escalate will be based on accrued safety/tolerability data at the prior dose level.
