What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a treatment called LCZ696 (also known as Entresto, a medication for heart failure) for individuals with stable heart failure and a reduced ejection fraction. Researchers aim to determine if adding icatibant can help manage blood pressure effects when starting LCZ696. Participants will alternate between receiving LCZ696 with either icatibant or a placebo (a substance with no therapeutic effect) to compare results. The trial seeks individuals with heart failure symptoms who have not been hospitalized in the last six months and are not currently taking LCZ696. As a Phase 4 trial, this research aims to understand how the already FDA-approved and effective treatment benefits more patients.

Will I have to stop taking my current medications?

Yes, you will need to stop taking your regular angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) before starting the trial. There is a 48-hour period without these medications before you begin the study.

Will I have to stop taking my current medications?

Yes, you will need to stop taking your regular angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) before starting the trial. There is a 48-hour period without these medications before you begin the study.

What is the safety track record for these treatments?

Research has shown that LCZ696, also known as Entresto, is as safe as other heart medications like ACE inhibitors and ARBs. Studies have found it to be generally well-tolerated in people with heart failure. Some individuals might experience low blood pressure, especially when starting the treatment, but overall, the benefits outweigh the risks.

For icatibant, safety data from many patients over several years suggest it is generally well-tolerated as well. It has been used safely in various dosing situations. However, individuals with certain heart conditions, such as unstable angina (chest pain), should exercise caution.

Both treatments have undergone extensive study, providing a good understanding of their safety. Those considering joining a trial involving these treatments can find reassurance in this information. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

LCZ696, also known as sacubitril/valsartan, is unique because it combines two active ingredients that work together to treat heart failure in an innovative way. Unlike traditional treatments like ACE inhibitors or beta-blockers, LCZ696 not only blocks harmful hormones but also boosts beneficial ones, helping the heart work more efficiently. Researchers are excited about LCZ696 because it has been shown to reduce the risk of hospitalization and improve survival rates for heart failure patients more effectively than some existing treatments. This dual-action approach offers a new hope for those struggling with heart failure, potentially leading to better outcomes and improved quality of life.

What is the effectiveness track record for LCZ696 in treating heart failure?

Studies have shown that LCZ696, a combination of sacubitril and valsartan, effectively treats heart failure with reduced ejection fraction (HFrEF). In a major study, LCZ696 reduced the risk of death from heart issues or the need for hospital visits by 20% compared to enalapril, a common heart failure medication. Another study confirmed that it also lowers the chance of readmission for heart failure. The drug blocks certain enzymes, helping to keep blood vessels relaxed and improving heart function. This treatment has proven effective in clinical settings and is already approved for heart failure. In this trial, participants will receive LCZ696 combined with either icatibant or a placebo, depending on their assigned treatment arm. ^{6 7 8 9 10}

LCZ696 (sacubitril/valsartan) was found to be safe and well tolerated in a study involving 50 healthy Japanese male subjects, with single oral doses of up to 600 mg showing no significant safety concerns.

The pharmacokinetics of LCZ696 demonstrated a dose-linear increase in exposure to its active components, with food intake affecting the absorption of the drug, particularly reducing the maximum concentration (C max) of sacubitril by 72%.

Sacubitril, a component of the heart failure treatment sacubitril/valsartan, was found to inhibit the transporters OATP1B1 and OATP1B3 in vitro, but this inhibition did not lead to significant changes in the pharmacokinetics of simvastatin in healthy subjects.

In a clinical study with 26 participants, co-administration of simvastatin with LCZ696 showed only minor decreases in the maximum concentration (Cmax) of simvastatin and its active metabolite, indicating that the combination is generally safe and well tolerated without clinically relevant interactions.

In the PARADIGM-HF trial, sacubitril/valsartan significantly reduced the risk of death from cardiovascular causes or hospitalization for worsening heart failure compared to the ACE inhibitor enalapril, demonstrating its efficacy in treating chronic heart failure with reduced ejection fraction (HFrEF).

Sacubitril/valsartan was generally well tolerated, with no increase in life-threatening adverse events, although it did have a higher incidence of symptomatic hypotension compared to enalapril, indicating it is a safer and more effective alternative for managing HFrEF.

Sacubitril/valsartan (Entresto) is a novel dual-acting angiotensin receptor-neprilysin inhibitor (ARNi) that has shown efficacy in treating heart failure in patients with both preserved (HFpEF) and reduced ejection fraction (HFrEF).

Recent studies have further supported the effectiveness of this combination drug in managing heart failure, highlighting its potential as a significant treatment option for patients with varying types of heart failure.

LCZ696 (sacubitril/valsartan) significantly reduces both systolic and diastolic blood pressure in patients with hypertension, with a total of 6,064 participants analyzed across 12 randomized controlled trials.

The antihypertensive effect of LCZ696 is dose-dependent, with higher doses (200 mg and 400 mg) leading to greater reductions in blood pressure compared to lower doses and angiotensin receptor blockers.

Effects of LCZ696 (Sacubitril/Valsartan) on Blood Pressure in Patients with Hypertension: A Meta-Analysis of Randomized Controlled Trials. Geng, Q., Yan, R., Wang, Z., et al.[2021]

Sacubitril/valsartan (LCZ696) has been shown to be an effective and safe treatment for hypertension, outperforming angiotensin receptor blockers (ARBs) in reducing both systolic and diastolic blood pressure across various dosages in a meta-analysis of 11 randomized controlled trials involving 6028 participants.

The study found that LCZ696 significantly reduced systolic blood pressure by up to 5.50 mm Hg and diastolic blood pressure by up to 2.51 mm Hg compared to ARBs, with no significant increase in adverse effects, indicating its potential as a superior option for managing high blood pressure.
