Program of Angiotensin-Neprilysin Inhibition in Admitted Patients With Worsening Heart Failure (PREMIER)

Phase 4Active Not RecruitingNCT05164653

Saga University400 enrolled

Overview

The aim of this study is to assess the treatment effect of sacubitril valsartan versus conventional therapy for heart failure (HF) in admitted patients due to exacerbation of HF on the N-terminal fragment of pro-B-type natriuretic peptide (NT-proBNP) concentrations.

The high rate of rehospitalization and mortality of patients hospitalized for acute exacerbation of HF, especially at the early phase after discharge, has long been a serious clinical concern. However, few trials evaluating drug therapies on the post-acute phase of HF showed positive and/or satisfying results. Therefore, it is urgently required to establish an efficient treatment strategy at that phase. Sacubitril valsartan is an angiotensin receptor-neprilysin inhibitor that was approved in Japan in 2020 for patients who are taking standard care of HF. In this investigator-initiated, multicenter, 8-week, randomized controlled study (PREMIER), the investigators try to assess the effect of in-hospital initiation of sacubitril valsartan, compared to standard HF treatment, in patients who were admitted due to worsening heart failure, on the NT-proBNP concentrations.

Interventions

Sacubitril Valsartan Sodium HydrateDRUG

Switch from the ACE inhibitor or ARB that was taken before the allocation, and start oral administration twice daily with a starting dose of 50 mg of sacubitril valsartan. The duration of administration of the ACE inhibitor or ARB before allocation does not matter, but when switching from the ACE inhibitor, administration of sacubitril valsartan should be started at least 36 hours after the final administration of the drug. After the start of administration, the dose is gradually increased to 100 mg and 200 mg once at intervals of 2 to 4 weeks, referring to the latest package insert and safety and tolerability standards. At that time, if the doctor in charge determines that the dose is not tolerated after the dose is increased, the dose may be reduced to the previous dose or the drug may be suspended depending on the medical situation.
