Amino Acid Therapy for Acute Kidney Injury
(BRAVE-HEART Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests whether an amino acid infusion can prevent acute kidney injury in children undergoing heart surgery. It seeks to determine if this treatment not only reduces kidney problems but also decreases the time spent on ventilators post-surgery. Participants will receive either an amino acid infusion or a placebo (a look-alike substance with no active drug) during and after their surgery for up to 72 hours. Children expected to be at high risk for kidney problems after heart surgery are a good fit for this trial. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of participants.
Do I have to stop taking my current medications for the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that this treatment is likely to be safe for humans?
Earlier studies have shown that administering amino acids through an IV is safe. Research suggests these infusions protect the kidneys, particularly in patients undergoing heart surgery. This indicates the treatment might be well-tolerated, as it has been tested in similar contexts.
Although these studies involved adults, they provide a strong basis to expect similar safety in children. The research consistently shows that amino acids can reduce the risk of kidney problems without causing major issues. So far, no strong evidence of serious side effects has emerged. This suggests that the amino acid treatment is likely safe for prospective participants in this clinical trial.12345Why do researchers think this study treatment might be promising for acute kidney injury?
Most treatments for acute kidney injury (AKI) focus on managing symptoms and supporting kidney function, like dialysis or medication to control blood pressure and fluid levels. But Amino Acid Infusion is unique because it targets the root cause of kidney damage by potentially enhancing the repair and regeneration of kidney cells. Researchers are excited about this treatment because amino acids are the building blocks of proteins, and they believe infusing them directly could help the kidneys heal faster and more effectively. This approach could offer a new way to address AKI beyond just managing symptoms.
What evidence suggests that an amino acid infusion might be an effective treatment for acute kidney injury?
Research has shown that administering amino acids directly into the bloodstream can protect the kidneys. In earlier studies, patients who received these amino acid infusions during heart surgery experienced fewer sudden kidney problems compared to those who received a placebo, a harmless substance. One study found that amino acids reduced the duration of kidney issues and improved kidney function in the days following surgery. Additionally, these infusions have increased a measure of kidney health called eGFR. Although some past results have varied, the overall evidence suggests that amino acid infusions could benefit kidney protection. Participants in this trial will receive either an Amino Acid Infusion or a Placebo Infusion for up to 72 hours to evaluate their effectiveness in treating acute kidney injury.12346

Are You a Good Fit for This Trial?
The BRAVE-HEART trial is for children undergoing cardiac surgery who are at risk of acute kidney injury. They must be receiving mechanical ventilation post-surgery. There's no specific information on exclusion criteria provided, but typically participants with conditions that could interfere with the study or pose additional risks would not be eligible.Inclusion Criteria
Exclusion Criteria
Timeline for a Trial Participant
Screening
Participants are screened for eligibility to participate in the trial
