The Complaint alleges that defendants violated Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, and Rule 10b-5 promulgated thereunder. The class period begins on September 27, 2004 after Defendants announced the interim results of the CART 2 study of the AGI-1067 drug. The Complaint alleges, among other things, that the Company's statements regarding the CART 2 study of AGI-1067 in the September 27, 2004 press release and conference call and in the September 28, 2004 interview that defendant Medford gave were false and misleading because the interim results were incomplete, misleading and resulted from manipulation of the study. Plaintiffs claim that defendants were motivated to manipulate the study to produce results that would induce a major pharmaceutical company to partner with it to complete the development and commercialization of AGI-1067. In response to defendants' hyping of the misleading interim results, Plaintiff charges, Atherogenics' stock price skyrocketed, rising 71% in unusually heavy after hours trading on September 27, 2004.

On November 22, 2004, defendants were forced to admit that the percentage of regression of plaque in patients using AGI-1067 was only slightly more than half as much as had been reported in the interim results defendants had announced two months earlier. In addition, defendants revealed that the Phase IIb results, though based on twice the patient population, showed that the relative difference between treatment with AGI-1067 and Standard of Care regime was not statistically significant. The market was stunned, and the stock price dropped precipitously. Then, on January 3, 2005, the Company announced that it had decided to increase the number of patients in the Phase III study for the drug from 4000 to 6000 patients, that the study would be longer in duration, and that the Company needed to raise more cash to fund the study. On this news, the Company's stock fell again, this time 20% to close at $18.72 on unusually heaving trading. On January 5, 2005, the Company disclosed in a SEC filing that the SEC and NASD had commenced informal inquiries into the Company's September 27, 2004 announcement of interim results of the study.
