(-)-Epicatechin and Pulmonary Arterial Hypertension

September 9, 2014 updated by: University of California, San Francisco

An Open Label Pilot Study of Purified (-)-Epicatechin to Improve Hemodynamics in Pulmonary Arterial Hypertension

Pulmonary arterial hypertension (PAH) is a progressive disease that results in severe activity limitation and death. There are few treatments for PAH and the available medications are expensive, difficult to administer and have significant toxicities.

(-)-Epicatechin is a non-toxic compound that naturally occurs in foods such as tea, wine and chocolate. Clinical intervention studies using dark chocolate in normal volunteers and subjects at risk for or with established cardiovascular disease have demonstrated improvements in peripheral and coronary vascular endothelial function, blood pressure, lipids, glucose tolerance and inflammatory markers.

Our study intends to examine the hemodynamics effects of purified (-)-epicatechin in subjects with pulmonary arterial hypertension. We hypothesize purified (-)-epicatechin will reduce pulmonary vascular resistance in patients with pulmonary arterial hypertension.

Design Details

  • Primary Purpose: Treatment
  • Allocation: N/A
  • Interventional Model: Single Group Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: (-)-Epicatechin
A single dose of 100mg or 200mg (-)-Epicatechin to be administered orally
Drug: (-)-Epicatechin
A single dose of purified (-)-epicatechin will be administered orally to subjects after a regularly scheduled right heart catheterization. The subjects will be monitored for 5 hours and released.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Pulmonary Vascular Resistance Index
Time Frame: up to 5 hours after right heart catheterization
This study will assess acute hemodynamic effects, specifically effects on pulmonary vascular resistance index (PVRI), of a single dose of purified (-)-epicatechin in patients with patients with PAH.
up to 5 hours after right heart catheterization

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Endothelial function and hemodynamics
Time Frame: up to 5 hours after right heart catheterization
Secondary objectives are to determine if endothelial function, right heart function, nitric oxide and mitochondrial function improve following consumption of purified (-)-epicatechin.
up to 5 hours after right heart catheterization
