Must have

Be older than 18 years old

Timeline

Screening 3 weeks

Treatment Varies

Follow Up day 1: predose, 5 minutes, 15 minutes, 0.5, 1, 2, 3, 4 and 8 hours postdose, day 7: predose, 5 minutes, 15 minutes, 0.5, 1, 2, 3, 4, 8 and 24 hours postdose

Summary

This trial is testing a new drug, MK-3475, for safety and effectiveness in reducing pulmonary vascular resistance (PVR) in people with PH-COPD. The hypothesis is that MK-3475 will be better than placebo at reducing PVR.

Experimental Treatment

Placebo Group

Group I: Part 2: MK-5475Experimental Treatment1 Intervention

Participants receive MK-5475 32 µg, 100 µg, 195 µg or 380 μg QD via inhalation from Days 1-28.

Group II: Part 1: MK-5475Experimental Treatment1 Intervention

Participants receive MK-5475 360 μg once daily (QD) via inhalation from Days 1-7. Following review of pharmacokinetic (PK) and safety data, a second 7 days of dosing may be initiated. A dose of up to 360 μg up to twice a day may be administered based on PK data in these participants.

Group III: Part 1: PlaceboPlacebo Group1 Intervention

Participants receive placebo QD via inhalation from Days 1-7.

Group IV: Part 2: PlaceboPlacebo Group1 Intervention
