Brief summary

The purpose of this research study is to determine whether early administration of Dexrazoxane prevents Doxorubicin induced cardiotoxicity.

Detailed description

This is a study on volunteers to determine effective dose of dexrazoxane in degrading Topoisomerase 2 b in human blood samples. Each participant will receive one dose of dexrazoxane. Blood samples will be collected to determine the time course and degradation of Topoisomerase 2b and Topoisomerase 2a
