Trial Outcomes & Findings for The Effects of Sacubitril/Valsartan on Cardiac Oxygen Consumption and Efficiency of Cardiac Work in Heart Failure Patients (NCT NCT03300427)

NCT ID: NCT03300427

Last Updated: 2024-01-05

Results Overview

Positron emission tomography (PET) imaging and echocardiography were performed before randomization (after a minimum of 4 weeks on stable dose of 80 mg BID or 160 mg BID of valsartan) and repeated after 6 weeks on a stable dose of either 80 mg BID or 160 mg BID of valsartan or 100 mg BID or 200 mg BID of sacubitril/valsartan. Cardiac efficiency was calculated based on the following formula: Myocardial efficiency = ((SBP x SV x HR)/LV mass)/Kmono Where * SBP : Systolic blood pressure during PET * SV : Stroke volume (Echocardiography) * HR : Heart rate * Kmono: Mono-exponential clearance rate (11C-acetate PET- scan) * LV mass: Left ventricular mass Visit 3 was performed after the study treatment was on a stable dose for a minimum of 6 weeks. It could be performed before or after 8 weeks, based on when the last dose modification was performed. No imputation of missing data was performed.

Participant Flow

The patients who signed the ICF entered the screening/run-in period of the study. After the screening evaluations and confirmation of eligibility, the patients were allocated randomization numbers and randomized to receive the treatment assigned to each number in a blinded manner.

PRIMARY outcome

Timeframe: Baseline, Visit 3 (approximately Week 8)

Population: Full analysis set (FAS): consisted of all randomized patients who had received at least one dose of study medication in the treatment period and had at least one post-baseline assessment of any efficacy endpoints.

Positron emission tomography (PET) imaging and echocardiography were performed before randomization (after a minimum of 4 weeks on stable dose of 80 mg BID or 160 mg BID of valsartan) and repeated after 6 weeks on a stable dose of either 80 mg BID or 160 mg BID of valsartan or 100 mg BID or 200 mg BID of sacubitril/valsartan. Cardiac efficiency was calculated based on the following formula: Myocardial efficiency = ((SBP x SV x HR)/LV mass)/Kmono Where * SBP : Systolic blood pressure during PET * SV : Stroke volume (Echocardiography) * HR : Heart rate * Kmono: Mono-exponential clearance rate (11C-acetate PET- scan) * LV mass: Left ventricular mass Visit 3 was performed after the study treatment was on a stable dose for a minimum of 6 weeks.

Timeframe: Baseline, Visit 3 (approximately Week 8)

Population: Full analysis set (FAS): consisted of all randomized patients who had received at least one dose of study medication in the treatment period and had at least one post-baseline assessment of any efficacy endpoints.

In addition to the derivation of the primary endpoint, an alternative formula was used, where the viable myocardial energetic efficiency was derived as: Viable myocardial energetic efficiency = ((SBP x SV x HR)/LV mass) / vKmono Where vKmono is the viable myocardium clearance rate. This alternative parameter was included as a sensitivity analysis to exclude possible bias related to scar tissue in patients with ischemic myopathy.
