University of Pennsylvania
  Purpose
This study is looking to see if giving ranolazine to subjects on stable pulmonary hypertension specific therapies but with right ventricular dysfunction (RVEF <45%) would improve their outcome. This study is accompanied by a baseline comparison of the metabolic profiling/microRNA/iPS cells of subjects with and without right ventricular dysfunction.

Condition Intervention
Pulmonary Hypertension Drug: Ranolazine Drug: Placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Randomized, Double-blind, Placebo Controlled, Multi-center Study to Assess the Effect of Ranolazine on Outcomes in Subjects With Pulmonary Hypertension and Right Ventricular Dysfunction Accompanied by a Comparative Study of Cellular Metabolism in Subjects With Pulmonary Hypertension With and Without Right Ventricular Dysfunction

Primary Outcome Measures:
  • Number and percentage of subjects with high risk profile at end of the study [ Time Frame: 6 months ]
    Number and percentage of subjects with high risk profile at Week 26. Patients with high risk profile are defined as patients with clinical worsening events or lack of clinical improvement at the end of the study.


Secondary Outcome Measures:
  • Glucose and lipid metabolites [ Time Frame: baseline ]
    Measure differences in glucose and lipid metabolism in subjects with and without RV dysfunction at baseline.

  • Changes from baseline in glucose and lipid metabolism [ Time Frame: 6 months ]
    Measure fold changes in glucose and lipid metabolism in subjects with persistent right ventricle dysfunction after treatment with and without ranolazine.


Estimated Enrollment: 40
Study Start Date: July 2013
Estimated Study Completion Date: December 2018
Estimated Primary Completion Date: December 2018 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Ranolazine
Ranolazine at 500mg by mouth twice per day and after two weeks will increase to 1000mg by mouth twice per day
Drug: Ranolazine
Ranolazine at 500mg by mouth twice per day and after two weeks will increase to 1000mg by mouth twice per day and continue for a total of 26 weeks.
Other Name: Ranexa
Placebo Comparator: Placebo
Placebo by mouth twice per day
Drug: Placebo
Placebo by mouth twice per day for a total of 26 weeks.
No Intervention: Observational
Patients with pulmonary hypertension who have normal RV function (RVEF >=45%) will undergo same procedures in the observational arm but will not receive an intervention.
