Infinity and MedImmune Announce Approval for Generic Name for Novel Hsp90 Inhibitor

CAMBRIDGE, Mass. and GAITHERSBURG, Md., Feb. 4, 2008 (Healthcare Sales & Marketing Network) -- Infinity Pharmaceuticals, Inc. (NasdaqGM:INFI ) and MedImmune today announced that the United States Adopted Names (USAN) Council, in consultation with the World Health Organization (WHO) International Nonproprietary Names Expert Committee, has approved the use of the nonproprietary or generic name ``retaspimycin'' for the companies' lead heat shock protein 90 (Hsp90) inhibitor, IPI-504. Retaspimycin hydrochloride is currently being evaluated in clinical trials for the potential treatment of a variety of solid tumor cancers, including gastrointestinal stromal tumors, non-small cell lung cancer, and hormone resistant prostate cancer.

About USAN

The USAN Council serves health professionals in the United States by selecting simple, informative, and unique nonproprietary names for drugs by establishing logical nomenclature classifications based on pharmacological and/or chemical relationships to ensure that drug information is communicated accurately and unambiguously. The USAN Council aims for global standardization and unification of drug nomenclature by working closely with the International Nonproprietary Name Programme of WHO and various national nomenclature groups.

About Retaspimycin

Retaspimycin, also known as IPI-504, is a small molecule drug candidate being developed jointly by Infinity and MedImmune. The drug product, retaspimycin hydrochloride for injection, has been generally well-tolerated and has shown promising biological activity in Phase 1 clinical trials in patients with metastatic and/or unresectable gastrointestinal stromal tumors (GIST) and patients with advanced non-small cell lung cancer (NSCLC). The companies are currently conducting the expansion stage of the Phase 1 trial in patients with refractory GIST and other soft tissue sarcomas and the Phase 2 portion of the Phase 1/2 trial in advanced NSCLC. Retaspimycin hydrochloride is also being evaluated in a Phase 2 study in patients with hormone-refractory prostate cancer and a Phase 1b study of retaspimycin in combination with Taxotere(r) in patients with advanced solid tumors. In preclinical studies, retaspimycin has been shown to inhibit Hsp90 potently and selectively, thereby killing cancer cells.
