Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18 and older with a durable CF-LVAD and NYHA classification II to IV.

Probably not a fit

Patients with symptomatic hypotension, severely reduced kidney function, or a history of adverse reactions to similar medications may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This pilot study aims to assess the safety and efficacy of sacubitril-valsartan, an angiotensin receptor-neprilysin inhibitor, in patients who have undergone implantation of a continuous flow left ventricular assist device (CF-LVAD). Participants will be monitored for short-term (3 months) and long-term (6 and 12 months) outcomes compared to standard oral vasodilator therapy. The study will include adults with stage D heart failure and will evaluate how well the new treatment is tolerated and its effectiveness in improving patient outcomes.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option that improves heart failure management in patients with LVADs.

How similar studies have gone: Other studies have shown promising results with similar approaches, but this specific application is relatively novel.
