In Brief

A Phase 1 clinical trial evaluating Beta-hydroxy-butyrate for Heart Failure and Type 2 Diabetes Mellitus. Completed, enrolled 41 participants across 2 sites.

Detailed Summary

To examine the effect of an increase in plasma beta-hydroxy-butyrate (B-OH-B) levels, spanning the physiologic and pharmacologic range (+0.5, +2.0, and +5.0 mmol/L), on: (i) parameters of left ventricular (LV) systolic and diastolic function utilizing cardiac magnetic resonance imaging (MRI) and (ii) myocardial glucose uptake using positron emission tomography (PET) with 18F-fluoro-2-deoxy-D-glucose in type 2 diabetic patients with Class II-III New York Heart Association (NYHA).

Interventions

Beta-hydroxy-butyratedrug

Following completion of the baseline MRI and blood samples, subjects will be divided into three groups (26 subjects per group). Each group will receive a 6-hour (3-hour in group III) prime-continuous infusion of racemic B-OH-B (100 mg/mL solution; pH adjusted to 7.4) to increase the plasma B-OH-B concentration by 0.5, 2.0, and 5.0 mmol/L. GROUP I: Prime = 0.4 mg/kg.min for 20 minutes and constant rate = 0.2 mg/kg.min until study end GROUP II: Prime = 1.5 mg/kg.min for 20 minutes and constant rate = 0.75 mg/kg.min until study end GROUP III: Prime = 4.0 mg/kg.min for 20 minutes and constant rate = 2.0 mg/kg.min until study end
