Par Pharmaceutical Announces Product Collaboration with Spectrum Pharmaceuticals, Inc.

Par Gains Access to Several Generic Injectable and Ophthalmic Products Currently Awaiting FDA Approval, Including Potential First-to-File Sumatriptan Injection

SPRING VALLEY, N.Y., Feb. 23 (HSMN NewsFeed) -- Par Pharmaceutical Companies, Inc. (NYSE: PRX ) today announced that it has entered into a collaborative agreement with Spectrum Pharmaceuticals, Inc. to develop and market generic drugs, including generic versions of injectable and ophthalmic pharmaceuticals. Spectrum, located in Irvine, California, is a specialty pharmaceutical company that develops both proprietary and generic drugs.

"Our collaboration with Spectrum will expand the therapeutic scope, as well as the size of Par's generic product pipeline," said Scott Tarriff, president and chief executive officer. "This agreement provides Par access to generic injectable and ophthalmic drugs, and adds a highly-valued, first-to-file opportunity to our portfolio of potential new products. We look forward to working closely with our colleagues at Spectrum to make this a very successful alliance."

While Abbreviated New Drug Applications (ANDAs) have been filed on several of the products subject to the agreement, other product candidates are currently in development or will be subject to future development. Among the products included in the agreement is sumatriptan succinate injection 6 mg/0.5 mL, the generic version of GlaxoSmithKline's (GSK) Imitrex® Injection. Imitrex® Injection is used for the acute treatment of migraine attacks with or without aura, and the acute treatment of cluster headache episodes. Annual U.S. sales of Imitrex® Injection are approximately $220 million, according to IMS Health.

In 2004, Spectrum filed an ANDA containing a paragraph IV certification with the U.S. Food and Drug Administration seeking marketing clearance for its generic version of the drug. Spectrum and Par believe that Spectrum was the first to file and is entitled up to 180 days of marketing exclusivity for the product. Spectrum is currently in litigation with GSK, who has alleged that Spectrum's product infringes U.S. Patent No. 5,037,845. Spectrum has alleged that its product does not infringe this patent and that the patent is invalid and unenforceable.

Terms of the Agreement

Under the terms of the agreement, Spectrum will be responsible for the development of all products. Par will have exclusive rights to market, promote, sell and distribute the products in the U.S. Par will be responsible for all future sumatriptan litigation expenses. Spectrum will receive milestone payments in connection with each successfully developed product. Par and Spectrum will share the net profits generated by all marketed products. At Spectrum's request, Par will make an equity investment in the company during the next 24 months.
