Study of Dapansutrile Capsules in Heart Failure
Study Details
Study Description
Brief Summary
This is a Phase 1b randomized, double-blinded, single-center safety and pharmacodynamics study of sequential cohort, dose-escalating, repeat-dosing of dapansutrile or placebo (4:1 ratio) in subjects with stable systolic heart failure (HF) with LVEF≤40% symptomatic for NYHA functional classification II-III who show signs of systemic inflammation (high sensitivity plasma C reactive protein [hsCRP] > 2 mg/L). A total of 30 subjects will be enrolled in 3 sequential cohorts by randomized allocation (8 active and 2 placebo within each cohort). Progression to cohort 2 with dose escalation will occur following the Day 28 visit of the last subject in the first cohort. Progression to cohort 3 with dose escalation will occur following the Day 8 visit of the last subject in the second cohort.
Subjects will be screened and evaluated twice for eligibility: 1) at the time of Screening (up to 28 days prior to enrollment); and 2) at the Baseline visit, prior to randomization. Following enrollment, Baseline assessments will be conducted and the first dose of investigational product (either dapansutrile capsules or placebo capsules) will be administered at the clinical site upon completion of all assessment and collection of baseline parameters. Subjects will then self-administer investigational product once, twice or four times daily, depending on cohort, for up to fourteen (14) consecutive days beginning at the Baseline visit and continuing through the planned Day 14 visit. Subjects will return to the study clinic on Days 4, 8, 14 and 28 for follow-up visits. Additionally, subjects will be contacted for telephone follow-up on Day 42.

Outcome Measures
Primary Outcome Measures
- Adverse events [Screening through Day 42 follow-up]
Adverse events experienced by the patient will be recorded.
Secondary Outcome Measures
- Cardiopulmonary exercise test [Day 14]
Physician-supervised maximal aerobic exercise test will be administered using a metabolic cart that is interfaced with a motorized treadmill. Change in peak oxygen consumption in each group will be assessed.
- Transthoracic Doppler ECG - Left Ventricle Ejection Fraction [Day 14]
Changes in left ventricular ejection fraction will be analyzed.
- Transthoracic Doppler ECG - Left Ventricular Filling Pressure [Day 14]
Changes in estimated left ventricular filling pressure, measured as ratio of early diastolic transmitral pulsed wave Doppler flow velocity (E) to tissue Doppler velocity of the mitral annulus (e') will be analyzed.
- Bioimpedance analysis [Day 14]
Bioimpedance is a non-invasive, quick and safe technique that allows to estimate body composition compartments (total body water, intracellular water, extracellular water, fat mass, fat-free mass, lean mass). Change in total body water will be assessed.
- Kansas City Cardiomyopathy Questionnaire - Clinical Summary Score [Day 14]
Change in KCCQ score, a 23-item, self-administered instrument that independently measures a patient's perception of their health status, which includes heart failure symptoms. This scale is quantified in six domains: physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. Each domain is scored on a 0-100 scale with 100 being better and 0 being worse. Two summary scores are calculated: the Clinical Summary Score (mean of symptom and physical function domain scores) and the Overall Summary Score (mean of the symptom, physical function, social limitations and quality of life scores).
- Kansas City Cardiomyopathy Questionnaire - Overall Summary Score [Day 14]
Change in KCCQ score, a 23-item, self-administered instrument that independently measures a patient's perception of their health status, which includes heart failure symptoms. This scale is quantified in six domains: physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. Each domain is scored on a 0-100 scale with 100 being better and 0 being worse. Two summary scores are calculated: the Clinical Summary Score (mean of symptom and physical function domain scores) and the Overall Summary Score (mean of the symptom, physical function, social limitations and quality of life scores).
- Duke Activity Status Index [Day 14]
Change in Duke Activity Status Index, a self-administered questionnaire that measures a patient's functional capacity. The index consists of 12 "yes or no" questions, which are summed and used to calculate VO2peak and METS.
- Vital signs - Pulse [Day 14]
Changes in pulse will be analyzed.
- Vital signs - Blood Pressure [Day 14]
Changes in systolic and diastolic blood pressure will be analyzed.
- Vital signs - Temperature [Day 14]
Changes in body temperature will be analyzed.
- Vital signs - Respiratory Rate [Day 14]
Changes in respiratory rate will be analyzed.
- Safety Laboratory Measurements - Chemistry [Day 14]
Changes in blood chemistry will be analyzed.
- Safety Laboratory Measurements - Hematology [Day 14]
Changes in complete blood count will be analyzed.
- Physical Examination [Day 14]
A full or targeted physical examination of the patient's major body systems
- 12-lead electrocardiogram [Day 8]
Electrodes will be placed on the patient to obtain a recording of the electrical activity of the heart.
Other Outcome Measures
- Pharmacokinetics [Baseline (pre and post dose), Day 4, Day 8, Day 14 and Day 28]
Blood sample for determination of dapansutrile blood concentrations.
- Pharmacodynamics / Biomarkers [Baseline (pre and post dose), Day 4, Day 8, Day 14 and Day 28]
Blood sample for determination of levels of inflammatory biomarkers
