Trial Outcomes & Findings for Acute Dosing of MK-8892 in Participants With Pulmonary Arterial Hypertension (PAH) (MK-8892-003) (NCT NCT01934647)

NCT ID: NCT01934647

Last Updated: 2018-10-22

Results Overview

PVR assessments were performed throughout the right heart catheterization (RHC). Peak PVR reduction was determined to occur if 2 consecutive PVR measurements were at least 20% greater than the nadir PVR measurement.

PRIMARY outcome

Timeframe: Baseline and up to 5 hours post-dose

Population: Planned efficacy analysis could not be performed due to early study termination.

PVR assessments were performed throughout the right heart catheterization (RHC). Peak PVR reduction was determined to occur if 2 consecutive PVR measurements were at least 20% greater than the nadir PVR measurement.
