What is the purpose of this trial?

This trial tests whether low-dose carvedilol, a medication for heart conditions, can prevent heart failure in childhood cancer survivors who received high doses of anthracycline chemotherapy. Anthracyclines can harm the heart, raising the risk of heart failure, which occurs when the heart cannot pump blood effectively. Participants will be randomly assigned to take either carvedilol or a placebo (a pill with no active drug) for 24 months. The trial seeks individuals diagnosed with cancer before age 22, who completed treatment at least two years ago, and received high doses of anthracyclines without protective medication. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

You may need to stop taking certain medications before joining the trial. Specifically, you cannot use beta blockers or certain blood pressure medications within 30 days of enrollment. It's best to discuss your current medications with the trial team to see if any changes are needed.

Is there any evidence suggesting that carvedilol is likely to be safe for humans?

Research has shown that carvedilol is generally safe for individuals who survived cancer as children. Studies have found it to be well-tolerated, even with long-term use. For example, research involving childhood cancer survivors who took carvedilol found it safe, although it did not significantly improve heart muscle thickness. Another study suggested that carvedilol might help lower the risk of heart failure in these patients without causing major side effects.

Overall, carvedilol is considered safe and may help reduce the risk of heart problems in childhood cancer survivors. ^{1 2 3 4 5}

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

Carvedilol is unique because it targets the prevention of heart failure in childhood cancer survivors, a group that often faces heart issues due to previous cancer treatments. Unlike standard heart failure medications, which are typically used to treat symptoms after they appear, carvedilol is being explored for its preventive potential. Researchers are excited about this treatment because it could offer a proactive approach, potentially safeguarding heart health before problems develop. This could be a game-changer for improving the long-term quality of life for childhood cancer survivors.

What evidence suggests that carvedilol might be an effective treatment for preventing heart failure in childhood cancer survivors?

Research has shown that carvedilol, which participants in this trial may receive, might help prevent heart failure in children who survived cancer and received high doses of anthracyclines, a type of chemotherapy. Studies found that carvedilol improved an important marker related to heart health, suggesting it could protect the heart. Although carvedilol appeared safe for long-term use, it did not significantly improve some heart function measures. Overall, carvedilol is considered promising because it may reduce the risk of heart failure. ^{6 7 8 9 10}

Trial Overview

The study tests if low-dose Carvedilol can prevent heart failure in those exposed to high doses of anthracyclines during childhood cancer treatment. It includes lab biomarker analysis, pharmacogenomic and pharmacological studies, placebo comparison, quality-of-life assessment, and questionnaires.

How Is the Trial Designed?

Group I: Arm I (carvedilol) Experimental Treatment 6 Interventions

Patients receive low-dose carvedilol PO QD or BID for 24 months.

Group II: Arm II (placebo) Placebo Group 6 Interventions

Patients receive placebo PO QD or BID for 24 months.
