Acura engages in the research, development, and manufacture of pharmaceutical product candidates utilizing Acura's proprietary "Aversion Technology" and other technologies that purportedly provide abuse deterrent features to orally-administered pharmaceutical drug products containing abusable active ingredients, such as tranquillizers, stimulants, sedatives, decongestants, and various other opioid analgesics.

The complaint alleges that, during the Class Period, Acura and certain of its officers and directors concealed material adverse facts about the Company's lead product candidate, Acurox, an orally administered immediate release tablet containing oxycodone as its active ingredient and niacin as an oral abuse-deterrent. After repeated glowing announcements by Acura to its investors touting the strength of the clinical trials of Acurox and the drug's potential for obtaining FDA approval, and thus commercial viability, the market was stunned when, on April 20, 2010, the FDA posted, on its website, briefing materials for the April 22, 2010 meeting to consider the New Drug Application of Acurox advising that: Acura's Aversion Technology was nowhere near effective enough to warrant approval, that the Company's clinical data was defective, that its clinical studies were not properly designed, that the Company had wholly ignored specific directives from FDA over the past four years as to specific clinical trials and evidence Acura had to demonstrate, and that that no evidence had ever been presented to the FDA that the niacin additive discouraged abusers from abusing oxycodone.

On this news, Acura's stock price declined 42.5% in one day, to close at $6.25 in afterhours trading. On April 22, 2010, the FDA Joint Panel voted 19-1 against approving Acurox. On the same day, it was reported that the FDA had been prodding Acura to demonstrate the deterrent efficacy of niacin since at least May 2009. As a result of these disclosures, Acura's stock price declined 39%, to $3.20 per share, in the pre-market trading on April 23, 2010.
