Forodesine (INN; also known as Immucillin H; trade names Mundesine and Fodosine) is a transition-state analog inhibitor of purine nucleoside phosphorylase studied for the treatment of patients with T-cell acute lymphoblastic leukemia (T-ALL) and for treatment of B-cell acute lymphocytic leukemia (B-ALL).

Forodesine was originally discovered by Vern Schramm's laboratory at the Albert Einstein College of Medicine in New York and Industrial Research Limited in New Zealand.

Forodesine is being developed by BioCryst Pharmaceuticals. As of 2008, it is currently in phase II clinical trials..

In 2006, BioCryst entered into a licensing agreement with Mundipharma International Holdings Limited to develop and commercialize forodesine in markets across Europe, Asia, and Australasia for use in oncology.

In April 2017, forodesine was approved in Japan for the treatment of relapsed/refractory peripheral T-cell lymphoma.

• The European Commission granted a marketing authorisation valid throughout the European Union for Atriance on 22 August 2007 for acute lymphoblastic leukaemia. What benefit has Atriance shown during the studies? Atriance was shown to be effective in a proportion of the patients in both studies. In the first study, among the 39 children and young adults who se cancer had not responded to two or more previous treatments, five (13%) had a complete response to treatment after a month, with no evidence of disease and normal blood counts. In the second study, among the 28 adults and adolescents with cancer that had not responded to two or more previous tre atments, five (18%) had a complete response to treatment. In both studies, more patients had a partial response to Atriance treatment, with blood counts returning towards normal levels.
