4.5   Interaction with other medicinal products and other forms of interaction

No interaction studies have been performed. However, there are no known clinically significant interactions with other medicinal products or laboratory tests.

Clofarabine is not detectably metabolised by the cytochrome P450 (CYP) enzyme system. Therefore, it is unlikely to interact with active substances which inhibit or induce cytochrome P450 enzymes. In addition, clofarabine is unlikely to inhibit any of the major 5 human CYP isoforms (1A2, 2C9, 2C19, 2D6 and 3A4) or to induce 2 of these isoforms (1A2 and 3A4) at the plasma concentrations achieved following intravenous infusion of 52 mg/m2/day. As a result, it is not expected to affect the metabolism of active substances which are known substrates for these enzymes.

Clofarabine is predominately excreted via kidneys. Thus, the concomitant use of medicinal products that have been associated with renal toxicity and those eliminated by tubular secretion such as NSAIDs, amphotericin B, methotrexate, aminosides, organoplatines, foscarnet, pentamidine, cyclosporin, tacrolimus, acyclovir and valganciclovir, should be avoided particularly during the five days of clofarabine administration period (see sections 4.4, 4.8 and 5.2).


The liver is a potential target organ for toxicity. Thus, the concomitant use of medicinal products that have been associated with hepatic toxicity should be avoided wherever possible (see sections 4.4 and 4.8).

Patients taking medicinal products known to affect blood pressure or cardiac function should be closely monitored during treatment with clofarabine (see sections 4.4 and 4.8).
