Heart Failure With Reduced Ejection Fraction (HF-rEF) Clinical Trial
Official title:
A Multicenter, Randomized, Double-blind, Parallel Group, Active-controlled Study to Evaluate the Efficacy and Safety of LCZ696 Compared to Enalapril on Morbidity and Mortality in Japanese Patients With Chronic Heart Failure and Reduced Ejection Fraction.
The purpose of this study was to assess the effect of LCZ696 at a target dose of 200 mg b.i.d. compared to enalapril 10 mg b.i.d., in addition to the background heart failure (HF) treatment, on delaying time to first occurrence of either cardiovascular (CV) death or HF hospitalization events in Japanese patients with stable chronic heart failure (CHF), New York Heart Association (NYHA) classes II-IV and reduced ejection fraction (left ventricular ejection fraction (LVEF) ≤ 35%).
The study consisted of two parts: the core part and the Open label extension (OLE) epoch. The core part of this study was a multicenter, randomized, double-blind, double-dummy, parallel-group, active-controlled study to assess the effect of LCZ696 at a target dose of 200 mg b.i.d. and enalapril 10 mg b.i.d. on CV mortality and morbidity reduction in Japanese HF patients with reduced ejection fraction. Patients who met the eligibility criteria at screening entered a 2 week, single-blind, active treatment run-in epoch in which they received LCZ696 50 mg b.i.d. Patients who tolerated LCZ696 50 mg b.i.d. for 2 weeks were randomized in a 1:1 ratio to receive LCZ696 100 mg b.i.d. or enalapril 5 mg b.i.d. for 4 weeks during the double-blind treatment epoch. The patient randomization was stratified by using NT-proBNP measured at the screening visit as a stratification factor. The patients were then titrated up to the target dose of LCZ696 200 mg b.i.d. or enalapril 10 mg b.i.d. if they tolerated 4 weeks treatment of LCZ696 100 mg b.i.d. or enalapril 5 mg b.i.d. Dose adjustment (LCZ696 50-100 mg b.i.d. & enalapril 2.5-5 mg b.i.d.) was permitted if not tolerated at the target dose of study drugs during the double-blind treatment epoch. This was an event-driven study in which subjects remained on the study (regardless of whether receiving investigational medications) until the projected number of patients with primary events (approximately 57 events) had been reached. The Open label extension (OLE) epoch was conducted following the completion of the core part, with the aim to provide access to LCZ696 for eligible subjects until the marketed product was available in Japan or 2 years from the date of the first subject enrolled in the OLE epoch, whichever occurred first, and also to obtain the safety and tolerability data of long-term treatment with LCZ696. Upon completion of the core part, the eligibility of the subjects to enter the OLE epoch was assessed by the investigator at OLE baseline (Visit 301), which occurred on the same day as the end of study (EOS) visit of the core part (Visit 299). At this visit, subjects were switched to open-label LCZ696. At Visit 302 (2 to 4 weeks after Visit 301), subjects who tolerated the open-label LCZ696 and met the safety monitoring criteria were up-titrated to the next higher level of daily dose. Thereafter, subject visits occurred at 8 weeks, and then every 4 months until EOS visit for OLE epoch. ;
