What is the purpose of this trial?

This trial explores the effects of lysine chloride, a sodium-free chloride supplement, on patients with stable heart failure. Researchers aim to understand its impact on electrolyte balance and overall fluid levels in the body. Participants will receive either lysine chloride or a placebo three times a day for five days. The trial seeks individuals with heart failure who have not been hospitalized in the past 90 days, are on stable medication, and have a low serum chloride level. As an Early Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants a chance to be among the first to receive this new treatment.

Will I have to stop taking my current medications?

The trial requires that you stay on your current heart failure medications, but you may need to stop taking metformin during certain parts of the study. If you are using a thiazide diuretic or certain chloride-containing medications, you may need to stop those as well.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that lysine chloride is generally safe for humans. Studies have found that ʟ-lysine hydrochloride, similar to lysine chloride, is well-tolerated by people. It has been used in dietary supplements at doses up to 3.75 grams per day without causing major side effects. Additionally, taking lysine supplements usually does not lead to many negative effects. This suggests that lysine chloride might be safe to use. However, since this trial is in an early stage, researchers are closely monitoring it to ensure safety. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for heart failure?

Lysine chloride is unique because it offers a new approach to treating heart failure by potentially impacting blood volume management. Unlike the standard treatments, which often focus on improving heart function or reducing symptoms through medications like beta-blockers and ACE inhibitors, lysine chloride might work by directly influencing the body's fluid balance. Researchers are excited about this treatment because it could provide a quicker, more effective way to relieve symptoms of heart failure, with patients possibly seeing benefits within just days of starting therapy. If successful, this could represent a significant advancement in managing heart failure, offering hope to patients who need faster relief.

What evidence suggests that lysine chloride might be an effective treatment for heart failure?

This trial will compare Lysine Chloride with a placebo to evaluate its effects on heart failure. Research has shown that lysine supplements may benefit heart health. One study found that lysine improved the heart and blood vessels' ability to handle stress, suggesting it could support heart health by managing stress. Lysine is also safe for consumption, even in larger amounts. While this trial continues to investigate Lysine Chloride for heart failure, these early findings are promising and suggest it might help improve heart function. ^{1 2 6 7 8}

Are You a Good Fit for This Trial?

This trial is for stable heart failure patients with an ejection fraction below 40%, on chronic loop diuretic therapy, and a serum chloride level under 102 mmol/L. They must have no hospitalizations in the past 90 days, be on evidence-based treatments, and have a history of following medical advice. Exclusions include those unable to follow the study protocol, using certain medications like metformin or thiazide diuretics recently, with severe kidney issues or significant blood sugar problems.

Inclusion Criteria

My heart failure is stable, with no hospital visits in 3 months, and I'm on a strict medication regimen.

Meticulous history of medical compliance and attendance of appointments

Exclusion Criteria

I have taken a water pill in the last month.

My hemoglobin level is below 8.0 g/dL.

I am not taking medications like metformin that could cause acidosis, or I can stop metformin safely for the study.

What Are the Treatments Tested in This Trial?

Interventions

• Lysine Chloride
• Placebo

Trial Overview

The trial is testing how sodium-free chloride supplementation (Lysine Chloride) affects electrolyte balance and fluid status compared to a placebo in heart failure patients. The goal is to understand if manipulating chloride levels can improve heart function by studying changes in volume status and sodium retention.

How Is the Trial Designed?

Group I: Lysine Chloride Experimental Treatment 1 Intervention

Patients will be randomized to receive either lysine chloride or placebo. Patients will receive the study drug thrice daily for 5 days of randomized therapy, starting after the completion of a blood volume assessment.

Group II: Placebo Placebo Group 1 Intervention

Patients will be randomized to receive either lysine chloride or placebo. Patients will receive the study drug thrice daily for 5 days of randomized therapy, starting after the completion of a blood volume assessment.

l-Lysine monohydrochloride and l-lysine sulfate produced by Corynebacterium glutamicum CGMCC 7.266 are considered safe for animals, consumers, and the environment, with no safety concerns related to the genetic modification of the production strain.

Both forms of l-lysine are effective nutritional additives for all animal species, but they need protection against degradation in the rumen to be as effective in ruminants as they are in non-ruminants.

L-lysine monohydrochloride (LMH) is primarily used as a nonprescription supplement to help suppress recurrent herpes simplex infections, indicating its efficacy in managing this viral condition.

Recent studies suggest that LMH may have potential therapeutic uses beyond herpes, including applications in cardiovascular disease and osteoporosis, warranting further research into its broader health benefits.

Concentrated liquid l-lysine and l-lysine HCl produced from the genetically modified strain Corynebacterium casei KCCM 80190 are safe for use in animal feed, as they do not pose risks to animals, consumers, or the environment, and no harmful genetic modifications were detected in the final products.

While both forms of l-lysine are effective for non-ruminant animals, additional protection would be needed for ruminants to ensure the l-lysine remains effective in their digestive systems.

The use of l-lysine monohydrochloride and l-lysine sulfate produced by the genetically modified strain C. glutamicum CGMCC 17927 is safe for all animal species and does not pose safety concerns regarding the production strain, as no viable cells or recombinant DNA were found in the final products.

Both forms of l-lysine are effective nutritional additives for non-ruminant animals, but for ruminants, additional protection against degradation in the rumen is necessary to ensure efficacy.
