6. DITPA Acquisition

On October 16, 2003, we announced the acquisition of a novel product in clinical testing for the treatment of congestive heart failure ("CHF"). The product in development, 3,5-diiodothyropropionic acid ("DITPA"), is an orally active analogue of thyroid hormone that has demonstrated in preclinical and clinical studies to date the ability to improve cardiac function, with no significant adverse effects. We acquired DITPA through the acquisition of Developmental Therapeutics, Inc. ("DTI"), a private company established to develop DITPA, and the exclusive licensee of recently issued U.S. patent and pending U.S. and international patent applications covering DITPA. We acquired DTI in a stock transaction for 1,187,500 shares of our common stock valued at approximately $3.6 million using the average market price of our common stock over the five-day trading period, including and prior to the date of the merger in accordance with generally accepted accounting principles. We also made a cash payment of $171,250 to the licensor of the technology. In the fourth quarter of 2003, the total acquisition cost of $3.9 million was reported as acquired research and development in our consolidated statements of operations. An additional payment of 712,500 shares of our common stock was to be made only upon the achievement of positive pivotal study results or certain other substantial milestones within five years. In addition, a cash payment of $102,750 or, alternatively, an additional payment of 37,500 shares of our common stock, was to be made to the licensor of the technology upon achievement of such study results or such other substantial milestones within five years. In October 2006, we discontinued further enrollment in our Phase 2 study of DITPA in CHF. In addition to the discontinuation of our Phase 2 clinical study in CHF, the Department of Veteran's Affairs has indicated that it will discontinue its Cooperative Studies Program Phase 2 study of DITPA in CHF patients. In March 2009, we terminated our license to the DITPA technology. No specific milestones have been achieved related to this acquisition as of December 31, 2011 and no future payments of cash or shares of our stock are anticipated related to this acquisition.
