NCT02713126 | COMPLETED | Heart Failure

Inorganic Nitrite to Amplify the Benefits and Tolerability of Exercise Training in Heart Failure With Preserved Ejection Fraction (HFpEF) (INABLE-Training)
Sponsor:

Barry Borlaug

Information provided by (Responsible Party):

Barry Borlaug

Brief Summary:

Participants with heart failure with preserved ejection fraction will undergo 12 weeks of cardiac rehabilitation for exercise training (ET) and be randomized to either sodium nitrite or placebo through the training period. Study drug is administered 3 times daily with one of these doses being 30 minutes prior to onset of ET sessions throughout the12 week trial. The objective is to determine if the sodium nitrite improves the clinical responses and tolerability of ET.

Criteria
Inclusion Criteria

    • * Catheterization documented elevated filling pressures at rest (Pulmonary Capillary Wedge Pressure (PCWP)= ≥15 or Left Ventricular End-Diastolic Pressure (LVEDP) ≥18) or with exercise (PCWP ≥25) or
    • * Elevated Natruretic Peptide-proBNP (\>400 pg/ml) or B-Type Natriuretic Peptide (BNP)(\>200 pg/ml) or
    • * Echo evidence of diastolic dysfunction/elevated filling pressures manifest by medial E/e' ratio≥15 and/or left atrial enlargement and chronic treatment with a diuretic for signs or symptoms of heart failure
    • * Heart failure is primary factor limiting activity as indicated by answering # 2 to the following question
      • My ability to be active is most limited by
        • 1. Joint, foot, leg, hip or back pain
        • 2. Shortness of breath and/or fatigue and/or chest pain
        • 3. Unsteadiness or dizziness
        • 4. Lifestyle, weather, or I just don't like to be active
        • * No chronic nitrate therapy or not using intermittent sublingual nitroglycerin (requirement for \>1 sublingual nitroglycerin per week).
        • * No daily use of phosphodiesterase 5 (PDE5) inhibitors or soluble guanylyl cyclase activators and willing to withhold as needed use of PDE5 inhibitors for duration of study
        • * Ambulatory (not wheelchair / scooter dependent)
        • * Body size allows wearing of the accelerometer belt as confirmed by ability to comfortably fasten the test belt provided for the screening process.
        • * Willingness to wear the accelerometer belt for the duration of the trial
        Exclusion Criteria
        • * Recent (\< 1 month) hospitalization for heart failure
        • * Ongoing requirement for PDE5 inhibitor, organic nitrate or soluble guanylyl cyclase activators
        • * Hemoglobin (Hgb) \< 8.0 g/dl within 30 days prior to randomization

        • * Resting Heart Rate \> 110
        • * Previous adverse reaction to the study drug which necessitated withdrawal of therapy
        • * Significant chronic obstructive pulmonary disease that is a primary contributor to symptoms, in the opinion of the Investigator.
        • * Ischemia thought to contribute to dyspnea, in the opinion of the Investigator.
        • * Documentation of previous Ejection Fraction \< 40%
        • * Acute coronary syndrome within 3 months defined by electrocardiographic (ECG) changes and biomarkers of myocardial necrosis (e.g., troponin) in an appropriate clinical setting (chest discomfort or anginal equivalent)
