Summary

This trial is testing whether a drug called Entresto, which is given to people with heart failure, is more effective when taken with or without another drug called Aprepitant.

Who is the study for?

This trial is for black and white men and women, aged 18 or older, with heart failure (NYHA Class I-III) and an ejection fraction (EF) ≤55%. Participants must have stable symptoms, no recent hospitalizations for heart failure, not be on LCZ696 currently, and if female and of childbearing potential, use reliable contraception. Excluded are those with allergies to study drugs or related chemicals, history of angioedema or certain cardiovascular events within the last six months.

What is being tested?

The trial tests how blood pressure responds to a combination of Aprepitant vs Placebo during initiation and steady-state doses of Entresto (LCZ696). It's a double-blind study where participants randomly receive either the drug or placebo in two phases: starting dose (50 mg) and maintenance dose (200 mg bid or highest tolerated).

What are the potential side effects?

Potential side effects may include allergic reactions to medication components; changes in kidney function as measured by substances like Para-aminohippurate; contrast-related reactions due to Iohexol; gastrointestinal issues affecting drug absorption; hormonal imbalances impacting diabetes control.

Experimental Treatment

Group I: placebo, aprepitant, placebo, aprepitantExperimental Treatment5 Interventions

After a 48-hr washout, participants in this arm will be given LCZ696 50 mg and placebo (vehicle). After a 96-hr washout period, subjects will be given LCZ696 50 mg and aprepitant. Participants will then undergo uptitration of LCZ696 over seven weeks. On the 7th and 10th days of the 200 mg bid or highest tolerated dose of LCZ696, participants in this arm will receive placebo and aprepitant, respectively.
