Statin Therapy in Young Adult Survivors of Childhood Cancer

• Status: Completed
• Trial end date: 2016-03-01
• Target enrollment: 0
• Participant gender: All

Summary

Adult survivors of childhood cancer are at high risk of developing cardiovascular disease. Therapies used to treat many cancers, such as chemotherapy and radiation, likely cause damage to the surface of the artery wall called the endothelial layer, leading to the induction of atherosclerosis and eventual cardiovascular disease. HMG coenzyme A reductase inhibitors, or statins, improve endothelial function independent of cholesterol-lowering. In addition, statins have been shown to reduce arterial stiffness and slow arterial thickening. Despite strong evidence supporting the vascular benefits of statins in many different patient populations, these medications have never been studied in cancer survivors. Therefore, the overall objective of this study is to evaluate the effects of statin therapy on vascular health in young adult survivors of childhood cancer.

Twenty-four young adult (age 18-39 years old) survivors of childhood acute lymphoblastic leukemia (ALL) or non-Hodgkin's lymphoma (NHL) will be enrolled in a six-month randomized, double-blind (participants and investigators), placebo-controlled pilot clinical trial comparing the effects of atorvastatin versus placebo on endothelial function and other measures of vascular health.

Our primary objective is to evaluate the effects of 6-months of statin therapy on conduit artery endothelial function in young adult survivors of childhood cancer. The investigators hypothesize that, compared to placebo, atorvastatin will significantly increase brachial artery flow-mediated dilation in survivors of childhood acute lymphoblastic leukemia and non-Hodgkin's lymphoma.
