Read the Complaint

The complaint charges Axonyx, Marvin Hausman and Gosse Bruinsma with violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 promulgated thereunder. More specifically, the Complaint alleges that the Company failed to disclose and misrepresented the following material adverse facts which were known to defendants or recklessly disregarded by them: (1) that the Company’s only viable drug candidate, Phenserine, a acetylcholinesterase (“AChE”) inhibitor, failed to curb symptoms of Alzheimer’s disease; (2) that the Company knew or recklessly disregarded the fact that Phenserine failed to partially block the effects of AChE, an enzyme that breaks down a neurotransmitter in the brain important for memory and cognition; (3) that as a consequence of the foregoing, the Company would not be able to commercialize Phenserine, currently its only potential source of revenue; and (4) that as a result the Company's positive statements about the development and potential approval of Phenserine were lacking in all reasonable basis when made.

On February 7, 2005, Axonyx announced that Phenserine did not achieve significant efficacy in Phase III Alzheimer’s Disease trial. The news shocked the market. Shares of Axonyx fell $3.04 per share, or 62.68 percent, on February 7, 2005, to close at $1.81 per share.
