Renal failure, cytopenia reportedwith deferasirox
Novartis has issued a ‘Dear Health Care Professional’1
letter and a public communication,2 both endorsed byHealth Canada, advising of a possible associationbetween the use of Exjade [deferasirox] and renal failureand cytopenia.
According to Novartis, reports of renal failure havebeen received following the postmarketing use ofExjade;1,2 some of these reports had a fatal outcome. Thefatalities could have been because of the underlyingdiseases; however, the company says that it isimpossible to rule out a contributory role of Exjade.Discontinuation of Exjade in most of the nonfatal caseswas associated with improvement in patients’ condition,which is suggestive of a contributory role of Exjade. Thecompany says that serum creatinine levels should bemonitored twice before initiating Exjade, followed byweekly monitoring in the first month of treatment, andmonthly thereafter; proteinuria should be monitoredevery month and patients should be adequatelyhydrated. Also, Novartis has received reports ofcytopenia in patients receiving Exjade, most of whomhad pre-existing haematological disorders. Clinical trialshave revealed dose-dependent increases in serumcreatinine levels in patients receiving Exjade.1 Increasesin creatinine levels occurred at a greater frequency inExjade recipients, compared with deferoxaminerecipients.1.
