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.^{[citation needed]}

Forodesine is being developed by BioCryst Pharmaceuticals. As of 2008^[update], it is currently in phase II clinical trials.^{[2][needs update]}.

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.^[3]

In April 2017, forodesine was approved in Japan for the treatment of relapsed/refractory peripheral T-cell lymphoma.^[4][5]
