A new biological therapy (KER-012) with exercise for exercise capacity and thinking in heart failure

You may qualify if

• Adult ≥ 40 years of age;
• Body mass index ≥ 27 kg/m2;
• Left ventricular ejection fraction (LVEF) ≥ 0.50 with NYHA II-III;
• Established diagnosis of HFpEF based on medical history supported by at least one of the following 5 criteria (i through v, below) i. Documented hospitalization with HFpEF as a primary cause or other urgent outpatient visit for acute HFpEF (as primary cause) at which IV loop diuretic was provided as treatment (≥ 1 month prior to screening); ii. Increased left atrial (LA) size: AP dimension: ≥ 4.0 in men, > 3.8 in women; or LA length ≥ 5.0 cm or LA volume ≥ 55 mL or LA volume index≥ 29 mL/m2; iii. PCWP at rest > 15 mmHg (or LVEDP ≥ 18 mmHg) or ≥ 25 mmHg with exercise (or PCWP/CO ≥ 2.0 mmHg/L/min with exercise); iv. Either of the following at rest by Doppler and Tissue Dopper: a) for patients in sinus rhythm: E/e' ratio ≥ 15 at septal annulus, or E/e' ratio ≥ 13 at lateral annulus, or average E/e' ratio ≥ 14; for patients in atrial fibrillation E/e' ≥ 11 at the septal annulus; v. Elevated NT-proBNP ≥ 125 pg/mL (≥ 250 with chronic atrial fibrillation).
• Achievement of a respiratory exchange ratio (RER) at baseline CPET of ≥ 1.05 to ensure maximum volitional effort was provided;
• Ambulatory (not wheelchair/scooter-dependent) and able to perform CPET/6MWT/Chair stand evaluations;
• Stable dose of medications (defined as no new medication or change in existing dose of medication ≥ 50%) for at least 30 days prior to screening.

You can't join if

• Conditions anticipated to independently impact exercise capacity or clinical stability during the trial period; Current or recent (within 30 days) acute decompensated HF requiring intravenous diuretics or hospitalization;; Initiation of treatment with GLP-1 receptor agonist or SGLT2 inhibitor within 60 days of screening;; Planned cardiac surgery or catheter intervention during the period of trial participation;; Entry within 30 days of screening or plans to enter a weight loss program and/or cardiac rehabilitation or initiate any new exercise program during the study.
• Primary cardiomyopathy (e.g., constrictive, restrictive, infiltrative, toxic, hypertrophic, congenital), LVEF < 40% within the last 3 years, or active myocarditis;
• Lactating, pregnant, or planning to become pregnant;
• Non-cardiac organ system dysfunction or sufficient severity to predominate as the source of exercise intolerance in addition to the following specific criteria: pulmonary disease with chronic home daytime supplemental O2 dependence, severe anemia with hemoglobin < 9 g/dL or chronic kidney disease (CKD) with estimated GFR < 30 mL/min/1.73m2 based on the CKD-EPI equation.
