Effects of Dexrazoxane Hydrochloride on Biomarkers Associated With Cardiomyopathy and Heart Failure After Cancer Treatment (HEART)
- Study HIC#:1401013303
- Last Updated:09/15/2023
We will determine echocardiographic and serum biomarkers of cardiac injury in a study of long-term pediatric T-cell leukemia and Hodgkin lymphoma survivors enrolled on 3 front-line Children's Oncology Group (COG) clinical trials (POG 9404, 9425, 9426) between 1996-2001 with certain features. Our primary aim will be to determine whether patients randomized to the experimental dexrazoxane (DRZ) arms have decreased markers of myocardial injury compared with patients treated without dexrazoxane (DRZ). This will include a one-time measurement of an echocardiographic index of pathologic left ventricular (LV) remodeling (wall thickness-dimension ratio), complemented by serum biomarkers and a physical examination for signs and symptoms of cardiomyopathy/heart failure (CHF). We will also evaluate whether DRZ's cardioprotective effect is modified by anthracycline dose, chest radiation, and selected demographic factors (age at cancer diagnosis, current age, sex).

Trial Purpose and Description
This clinical trial studies the effects of dexrazoxane hydrochloride on biomarkers associated with cardiomyopathy and heart failure after cancer treatment. Studying samples of blood in the laboratory from patients receiving dexrazoxane hydrochloride may help doctors learn more about the effects of dexrazoxane hydrochloride on cells. It may also help doctors understand how well patients respond to treatment.
- Previously enrolled and randomized on POG 9404, 9425, or 9426
- Alive and in continuous first complete remission from their original cancer (T-cell leukemia/lymphoma [POG 9404] or Hodgkin lymphoma [POG 9425/9426])
- Not have been diagnosed with any subsequent malignancy, with the exception of non-melanomatous skin cancer(s). Patients with history of only subsequent non-melanomatous skin cancers remain eligible.
- All patients and/or their parents or legal guardians must sign a written informed consent (see Stratum 1 sample consent).
- Among patients who have relapsed or have experienced a subsequent malignancy other than non-melanomatous skin cancer since their original diagnosis, the study committee will review the available data (both from COG's Statistics and Data Center (SDC) and the participating institution) to determine if individual patients are to be selected for secondary aim arm only. The study will petition the IRB specifically for a waiver of consent to include any relapse and subsequent cancer data obtained from existing records for analysis of the secondary aims. Patients selected for Stratum 2 will be those for whom late relapse or subsequent cancer is reported but who lack clear confirmation in existing records (either at SDC or at the local institution).
