Brief summary

The purpose of the study is to evaluate how well tolerated and effective an angiotensin receptor-neprilysin inhibitor (sacubitril-valsartan) is in patients with contemporary durable continuous flow left ventricular assist device (CF-LVAD) implantation compared to usual care oral vasodilator therapy.

Detailed description

The aim of this pilot study is to prospectively determine the short-term (at 3 months) and long-term (at 6 and 12 months) safety and efficacy of an angiotensin receptor-neprilysin inhibitor (sacubitril-valsartan) in patients with contemporary durable continuous flow left ventricular assist device (CF-LVAD) implantation compared to standard-of-care (usual care) oral vasodilator therapy.

Interventions

DRUGSacubitril-Valsartan

Sacubitril-valsartan at low or equivalent dose to be initiated or added to patients randomized to this arm, and titrated up every 2-4 weeks, per standard practice guidelines and label recommendations per physician's discretion.

DRUGUsual care (standard-of-care) arm

Other oral vasodilator therapy to be continued or initiated to patients randomized to this arm, and titrated up every 2-4 weeks, per standard practice guidelines and label recommendations per physician's discretion.

Design outcomes

Primary

MeasureTime frameDescription
Incidence of drug discontinuation from drug-related adverse events due to sacubitril-valsartan versus standard-of-care oral vasodilator therapy at 3 months3 monthsIncidence of drug discontinuation from drug-related adverse events due to sacubitril-valsartan versus standard-of-care oral vasodilator therapy evaluated at 3 months. Incidence of drug discontinuation is defined as the number of patients exposed to the drug with an adverse event over the total number of patients exposed to the drug. An adverse event is defined as any one of the following: acute kidney injury with eGFR decline \> 25% from baseline, hyperkalemia with potassium \> 5.5 mM, hypotension with mean arterial pressure (MAP) \< 60 mm Hg, angioedema, dizziness, and/or cough.
