Rationale and design of TRANSITION: a randomized trial of pre‐discharge vs. post‐discharge initiation of sacubitril/valsartan

Abstract

Aims

The prognosis after hospitalization for acute decompensated heart failure (ADHF) remains poor, especially <30 days post‐discharge. Evidence‐based medications with prognostic impact administered at discharge improve survival and hospital readmission, but robust studies comparing pre‐discharge with post‐discharge initiation are rare. The PARADIGM‐HF trial established sacubitril/valsartan as a new evidence‐based therapy in patients with heart failure (HF) and reduced left ventricular ejection fraction (<40%) (rEF). In common with other landmark studies, it enrolled patients who were ambulatory at the time of inclusion. In addition, there is also still limited knowledge of initiation and up‐titration of sacubitril/valsartan in ACEi/ARB‐ naïve patients and in de novo HF with rEF patients.

Methods and results

TRANSITION is a multicentre, open‐label study in which ~1000 adults hospitalized for ADHF with rEF are randomized to start sacubitril/valsartan in a pre‐discharge arm (initiated ≥24 h after haemodynamic stabilization) or a post‐discharge arm (initiated within Days 1–14 after discharge). The protocol allows investigators to select the appropriate starting dose and dose adjustments according to clinical circumstances. Over a 10 week treatment period, the primary and secondary objectives assess the feasibility and safety of starting sacubitril/valsartan in‐hospital, early after haemodynamic stabilization. Exploratory objectives also include assessment of HF signs and symptoms, readmissions, N‐terminal pro‐B‐type natriuretic peptide and high‐sensitivity troponin T levels, and health resource utilization parameters.

Conclusions

TRANSITION will provide new evidence about initiating sacubitril/valsartan following hospitalization for ADHF, occurring either as de novo ADHF or as deterioration of chronic HF, and in patients with or without prior ACEI/ARB therapy. The results of TRANSITION will thus be highly relevant to the management of patients hospitalized for ADHF with rEF.
