Adeona Executes Manufacturing and Supply Agreement with TG United for reaZin™

ANN ARBOR, Mich., April 20, 2011 /PRNewswire/ -- Adeona Pharmaceuticals, Inc. (NYSE Amex: AEN), a developer of innovative medicines for serious central nervous system diseases, announced today that it has executed an agreement with TG United, Inc. of Brooksville, Florida, to provide commercial-scale manufacturing capabilities for reaZin. Adeona is developing reaZin, its product candidate for the dietary management of Alzheimer's disease and mild cognitive impairment, as a prescription medical food.

Top-line results from Adeona's clinical study evaluating reaZin for the dietary management of Alzheimer's disease and mild cognitive impairment were presented last week at the 63rd Annual Meeting of the American Academy of Neurology. In the patients administered reaZin, the primary outcome of increasing serum zinc and decreasing serum free copper was effectively demonstrated. In addition, the average cognitive function of the placebo group declined over 6 months in comparison to patients managed with reaZin. The cognitive function trends favoring the patients administered reaZin were observed in all three standardized cognitive tests and suggest that reaZin may provide an important dietary benefit to Alzheimer's disease patients.

"Executing this agreement for the manufacturing of our product candidate, reaZin, is an important step for commercialization," stated James S. Kuo, M.D., M.B.A., Adeona's Chief Executive Officer. "With the recent news that revised guidelines for diagnosing Alzheimer's disease could double the population size, we are excited that reaZin may be of benefit to this growing population, particularly in the earlier stages."

These statements are based upon current beliefs, expectations and assumptions and are subject to a number of risks and uncertainties, many of which are difficult to predict and include statements regarding the use of zinc as a potential dietary management for cognitive deficits in Alzheimer's patients, the size of the Alzheimer's population  and our intent to further commercialize development of reaZin as a prescription  medical food. The forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those set forth or implied by any forward-looking statements. Important factors that could cause actual results to differ materially from those reflected in Adeona's forward-looking statements include, among others, our failure to successfully commercialize reaZin for the management of Alzheimer's disease, the failure of reaZin to be accepted for dietary management of Alzheimer's disease,  failure of future clinical trials studying  reaZin to have favorable results, and other factors described in Adeona's report on Form 10-K for the year ended December 31, 2010 and any other filings with the SEC.
