Business Description
The company is a biopharmaceutical company engaged in research and development of proprietary immunoregulatory compounds for the treatment of autoimmune and cardiovascular diseases. The company is developing C5 complement inhibitors and Apogens, two classes of potential therapeutic compounds designed to selectively target specific disease causing segments of the immune system. The company believes that its C5 Inhibitors and Apogens, which are based upon immunoregulatory technologies, may have the advantage of achieving a higher level of efficacy with the potential for reduced side effects when compared to existing therapeutics approaches. The company anticipates it will file an Investigational New Drug Application for its first C5 Inhibitor product candidate, targeting the prevention of inflammation during cardiopulmonary bypass procedures, in the first quarter of 1996 and will thereafter commence clinical trials. The company anticipates that it will file an IND for its lead proprietary Apogen, MP4, for treatment of multiple sclerosis, in late 1996.

Use of Proceeds
The proceeds from the offering will be used to fund the company's research and development including preclinical and clinical studies and early stage manufacturing, to pay certain licensing fees and royalties, working capital and other general corporate purposes.
