Infinity and MedImmune Announce Issuance of U.S. Patent for Proprietary Heat Shock Protein 90 Inhibitors

Companies Also Granted European Orphan Drug Designation for IPI-504 for the Potential Treatment of Gastrointestinal Stromal Tumors

October 23, 2007: 09:17 AM EST

CAMBRIDGE, Mass. and GAITHERSBURG, Md., Oct. 23, 2007 (PRIME NEWSWIRE) -- Infinity Pharmaceuticals, Inc. (Nasdaq:INFI) and MedImmune, Inc. today announced that the United States Patent and Trademark Office issued a patent on October 16, 2007 for the companies' heat shock protein 90 (Hsp90) inhibitors, including investigational drug candidate IPI-504. U.S. Patent No. 7,282,493 includes composition of matter, pharmaceutical composition, method of treatment, and synthetic method claims directed to IPI-504 and other hydroquinone-containing ansamycin analogues. IPI-504, the companies' lead Hsp90 inhibitor, is currently being evaluated in two separate multi-center clinical trials in patients with gastrointestinal stromal tumors (GIST) and other soft tissue sarcomas, and in patients with non-small cell lung cancer. The patent is owned by Infinity and is co-exclusively licensed to MedImmune pursuant to the terms of the parties' collaboration agreement.

Infinity and MedImmune also announced today that the European Medicines Agency's (EMEA) Committee for Orphan Medicinal Products has granted IPI-504 orphan drug designation for the treatment of GIST. Orphan drug designation is granted by the EMEA to promote the development of products that may offer therapeutic benefits for diseases affecting fewer than five in 10,000 people in the European Union. Orphan drug designation provides opportunities for free protocol assistance, fee reductions for access to centralized community procedures before and after marketing authorization, and 10 years of market exclusivity following drug approval. On September 17, 2007, the companies announced that the U.S. Food and Drug Administration's Office of Orphan Products Development granted IPI-504 orphan drug designation for the treatment of GIST.

About IPI-504

IPI-504 is a small molecule drug candidate being developed jointly by Infinity and MedImmune. IPI-504 has been well-tolerated in its ongoing Phase 1 studies and has shown promising biological activity in a Phase 1 clinical trial in patients with relapsed, refractory GleevecĀ®-resistant GIST. IPI-504 is also being evaluated in a Phase 1/2 clinical trial in patients with advanced non-small cell lung cancer. In preclinical studies, IPI-504 has been shown to inhibit Hsp90 potently and selectively, thereby affecting cancer cells. IPI-504 has also demonstrated, in preclinical studies, broad potential to treat certain cancers as both a single agent as well as in combination with existing anti-cancer drugs. The water-based formulation of IPI-504 is delivered as an intravenous infusion. Infinity and MedImmune are currently developing and evaluating two oral Hsp90 inhibitors, which have both demonstrated potent and selective inhibition of Hsp90 in preclinical models.

About Gastrointestinal Stromal Tumors (GIST) and Hsp90

The American Cancer Society (ACS) reports that GIST is the most frequent form of gastrointestinal sarcoma, a life-threatening disease highly resistant to traditional cytotoxic chemotherapy or radiation treatment. The ACS estimates that between 4,500 and 6,000 Americans develop GIST each year. In the majority of GIST cases, specific mutations in cellular signaling enzymes ("kinases") called KIT or PDGFRA cause the growth and survival signal of the cell to become permanently active, leading to cancer. Both KIT and PDGFRA are client proteins of Hsp90, suggesting that inhibition of Hsp90 in GIST is an attractive area for clinical study.
