According to the law firm press release, Esperion is a pharmaceutical company that focuses on developing and commercializing oral low-density lipoprotein cholesterol ("LDL-cholesterol") lowering therapies for patients with hypercholesterolemia. Esperion's lead product candidate is ETC-1002, a once-daily small molecule designed to lower LDL-cholesterol levels. According to Esperion, ETC-1002 is designed to lower LDL-cholesterol while avoiding the side effects associated with other LDL-cholesterol lowering therapies on the market.

The complaint alleges that during the Class Period, defendants issued false and misleading statements and/or failed to disclose adverse information regarding Esperion's business and prospects, including that there was no clear path to approval for ETC-1002, and that the FDA had encouraged the Company to initiate a cardiovascular outcomes trial ("CVOT") and that completion of a CVOT could be necessary prior to approval of ETC-1002. As a result of these false statements and/or omissions, Esperion common stock traded at artificially inflated prices during the Class Period, reaching as high as $82 per share in intra-day trading.
