A Multiple Dose Titration Study of MK-8892 in Participants With Pulmonary Hypertension and Left Heart Disease (MK-8892-007)
A Multiple Dose Titration Trial to Study the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of MK-8892 in Patients With Pulmonary Hypertension and Left Heart Disease
This study will assess multiple doses of MK-8892 administered to participants with pulmonary hypertension "out of proportion" (PHOOP) and heart failure with reduced left ventricular ejection fraction (rEF). It is hypothesized that generally safe and well tolerated multiple doses of MK-8892 will achieve a true reduction from baseline in pulmonary vascular resistance (PVR) greater than 12%.
Sixteen participants with PHOOP/rEF were to receive multiple doses of MK-8892 titrated to the highest tolerated dose for each participant (up to 4 mg daily), and to undergo evaluation for safety and systemic hemodynamics and cardiac function. Only 4 participants were enrolled and completed the study due to a strategic business decision by the sponsor to terminate the clinical conduct of all MK-8892 ongoing trials including this trial.

Exclusion Criteria:
- Primary pulmonary arterial hypertension or veno-occlusive disease (WHO Group 1), or pulmonary hypertension secondary to other causes (WHO Groups 3 -5) including but not limited to autoimmune disease, connective tissue disease, and Eisenmenger syndrome
- Currently treatment with or anticipates use of nitrate, phosphodiesterase type 5 (PDE5) inhibitor, or medications known to induce or inhibit cytochrome P450 3A4 (CYP3A4) metabolism, and cannot be transitioned off of this therapy for >=7 days prior to dosing and through completion of this study

EXPERIMENTAL: MK-8892
Starting dose of 1 mg daily (oral); the dose may be titrated up on the 8th, 15th, and 22nd day of treatment to 2 mg, 3 mg, or 4 mg, respectively, for the duration of the study (28 days) as tolerated.
For participants who reach one or more of the down-dosing criteria, there is an opportunity to decrease the dose back to a previously well-tolerated dose level, or to ½ of the starting dose.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Percentage Change From Baseline in Pulmonary Vascular Resistance (PVR)
Time Frame: Baseline and Day 28
|
Pulmonary vascular resistance (PVR) is the general pressure which the right ventricle must counteract to pump blood through the lungs.
PVR was measured by right heart catheterization performed prior to dosing at baseline (Day 1) and 4 hours postdose on Day 28.
Percentage change in PVR from baseline at Day 28 was calculated as [(Baseline-Day 28)/Baseline].
Standard deviation is reported as a percentage.

Baseline and Day 28

Number of Participants Who Experienced an Adverse Event
Time Frame: Up to 42 days
|
An adverse event was defined as any untoward medical occurrence in the form of signs, symptoms, abnormal laboratory findings, or disease temporally associated with the use of the study drug or a study procedure, whether or not considered related to the study drug or study procedure.
Any worsening of a preexisting condition which is temporally associated with the use of the study drug is also an adverse event.
|
Up to 42 days
|
Number of Participants Who Discontinued Study Drug Due to an Adverse Event
Time Frame: Up to 28 days
|
An adverse event was defined as any untoward medical occurrence in the form of signs, symptoms, abnormal laboratory findings, or disease temporally associated with the use of the study drug or a study procedure, whether or not considered related to the study drug or study procedure.
Any worsening of a preexisting condition which is temporally associated with the use of the study drug is also an adverse event.
