Carvedilol in Preventing Heart Failure in Childhood Cancer Survivors


  • Study type

  • Study phase

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

This randomized phase IIb trial studies how well low-dose carvedilol works in preventing heart failure in cancer survivors exposed to high dose anthracyclines for management of childhood cancer. Patients who received high-dose anthracycline chemotherapy are at a much greater risk for developing heart failure compared to survivors who didn't get any anthracycline chemotherapy. Heart failure happens when the heart muscle has been weakened and can't pump blood as well as it should. Carvedilol may help lower the risk of cardiovascular complications.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
