ProEthic Pharmaceuticals Initiates Pivotal Phase III Trial for Fast-Acting Migraine Product Candidate

Trial to be conducted under Special Protocol Assessment

MONTGOMERY, Ala.--(HSMN NewsFeed)--May 22, 2006--ProEthic Pharmaceuticals, Inc., a privately funded specialty pharmaceutical company that acquires, develops and markets niche prescription products, announced today that it has initiated a Phase III clinical trial for PRO-513, the company's product candidate for the treatment of migraine headaches. The study is being conducted under the guidance of a Special Protocol Assessment (SPA) provided by the U.S. Food and Drug Administration (FDA). The SPA indicates that if the trial successfully meets its primary endpoints, the data will provide the basis for an efficacy claim in a marketing application to the FDA.

PRO-513 is a formulation of diclofenac potassium powder for oral solution, which utilizes a unique, patented Dynamic Buffering Technology (DBT) that has been demonstrated to enhance the pharmacokinetic profile of diclofenac. This new formulation is expected to offer migraine headache patients rapid pain relief combined with superior efficacy and tolerability. In a randomized, double-blind clinical trial, PRO-513 has been shown to provide systematic improvement of migraine symptoms within 15 minutes.

"PRO-513, and its unique formulation of diclofenac, represents a potentially new and improved treatment option for the 28 million Americans who experience debilitating migraine headaches," said Carl Whatley, Chairman and CEO of ProEthic Pharmaceuticals, Inc. "We are excited to be able to develop a product with strong potential advantages not only in safety and efficacy, but one that can offer the rapid relief that migraine sufferers so desperately seek."

About the IMPACT Trial

The Phase III trial for PRO-513, identified as the International Migraine Pain Assessment Clinical Trial (IMPACT), will enroll 650 patients in approximately 21 centers over the next eight months. The IMPACT trial is a multi-center, prospective, randomized, double-blind, parallel group, single dose, placebo-controlled study of the efficacy and safety of PRO-513 in adult subjects with migraine attacks. The primary endpoints for the trial are: pain relief, nausea, photophobia, and phonophobia. ProEthic anticipates filing a New Drug Application (NDA) for PRO-513 in early 2007 and expects to introduce the product in the U.S. in early 2008.

About PRO-513

In 2005, ProEthic obtained exclusive U.S. and Canadian marketing rights for PRO-513 from Applied Pharma Research, a Swiss drug development company. Additionally, ProEthic has obtained the rights to utilize PRO-513 clinical trial data from Novartis Pharmaceuticals. In the Phase III migraine study conducted by Novartis, PRO-513 was shown to be safe and effective in the treatment of migraine pain and symptoms associated with migraine, namely photophobia (sensitivity to light), phonophobia (sensitivity to sound), and nausea. Novartis recently obtained marketing approval for the product, under the trademark Voltfast®, in Switzerland and Portugal and is expecting approvals in over two dozen other European countries in 2006.
