The purpose of RHYME is to evaluate the safety and efficacy of ranolazine in Hypertrophic Cardiomypathy patients with chest pain or dyspnea despite treatment with standard medical therapy. This is a small, pilot, open-label (non-randomized) study of an approved drug for the treatment of angina in a novel patient population (adult patient population with hypertrophic cardiomyopathy).

Condition Intervention Phase
Hypertrophic Cardiomyopathy Drug: Ranolazine Phase 4

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Supportive Care
Official Title: Ranolazine for the Treatment of Angina in Hypertrophic Cardiomyopathy Investigation

Further study details as provided by Duke University:

Primary Outcome Measures:
  • QT Interval [ Time Frame: 60 Days ]
  • Number of Adverse Events Considered Probably or Possibly Related to Study Drug [ Time Frame: 60 Days ]
    Number of events that are considered probably or possibly related to study drug.

  • Drug Tolerability [ Time Frame: 60 days ]
    Total number of patients that tolerated 1,000mg BID dose and 500 mg BID dose

Secondary Outcome Measures:
  • Improvement in Number of Episodes of Angina Per Week [ Time Frame: Baseline and 60 Days post treatment ]
    Efficacy of ranolazine in HCM patients with respect to improvements in angina frequency (number of episodes of angina per week).

  • Seattle Angina Questionnaire (SAQ) [ Time Frame: 60 Days post treatment ]
    The Seattle Angina Questionnaire (SAQ) is a self-administered, 19-item questionnaire, a cardiac disease-related quality-of-life measure. The SAQ is well validated and sensitive to clinical changes. It has five subscales: physical limitation, angina stability, angina frequency, treatment satisfaction, and disease perception. The possible range of scores for each of the five subscales is 0 to 100, with higher scores indicating better quality of life.

  • Kansas City Cardiomyopathy Questionnaire (KCCQ) [ Time Frame: 60 days post treatement ]
    Kansas City Cardiomyopathy Questionnaire (KCCQ) (scores range from 0 to 100 with higher scores representative of a higher quality of life; clinically important changes are considered > 10 points and >5 points, respectively, as previously established
