Mitoxantrone Hydrochloride (marketed as Novantrone and generics)
Audience: Neurological and Oncological healthcare professionals, risk managers
[Posted 07/29/2008] FDA reminded health care professionals who treat patients with mitoxantrone about recommendations that left ventricular ejection fraction (LVEF) be evaluated before initiating treatment and prior to administering each dose of mitoxantrone. FDA offered additional recommendations for cardiac monitoring to detect late-occurring cardiac toxicity, and provided information for patients with multiple sclerosis who receive the drug.
These recommendations were established in 2005 in response to post-marketing reports and case reports in the medical literature that described decreases in LVEF or frank congestive heart failure in patients with MS who had received cumulative doses of mitoxantrone that were lower than 100 mg/m2. Since that time, FDA has received information from a post-marketing safety study that demonstrated there is poor adherence to these recommendations in clinical practice. FDA is working with the manufacturers to educate healthcare providers to adhere to cardiac monitoring recommendations for patients with MS.
