CTI Biopharma Accused of Misleading Investors About the Effectiveness of its Drug

According to the complaint, CTI Biopharma failed to disclose that: (i) pacritinib was attributed as a potential cause in the death and injuries of several patients; (ii) its clinical trials showed the dangers of pacritinib usage; (iii) the company's new drug application would likely be withdrawn; and (iv) this would affect the company's future revenues. During 2014 through 2015, the company filed several Form 10-Q's and Form 10-K's with the U.S. Securities and Exchange Commission ("SEC") touting the effectiveness of pacritinib. On September 24, 2015, CTI Biopharma filed with the SEC its Prospectus Supplement to complete the offering of 10 million shares of common stock offered with a previously filed Registration Statement, which was required to disclose known trends or uncertainties likely to have an impact on the company's operations.

Then, on February 8, 2016, the company issued a press release announcing that a partial clinical hold had been placed on pacritinib by the U.S. Food and Drug Administration ("FDA"). The company further disclosed that the FDA had identified several fatal and life-threatening safety issues in pacritinib-treated patients, including: heart failure; hemorrhage, including intracranial hemorrhage; and arrhythmias, including sudden death. On this news, CTI Biopharma stock fell $0.68 per share, or over 60%, to close at $0.44 per share on February 8, 2016. On February 9, 2016, the company announced that the FDA had placed a full clinical hold on pacritinib. Under the full clinical hold, all patients must discontinue pacritinib immediately, and the company may not enroll any new patients or start pacritinib as initial or crossover treatment. The clinical hold led the company to withdraw its previously submitted new drug application for pacritinib. On this news, CTI Biopharma stock fell over 40% during intraday trading, to close at $0.30 per share on February 10, 2016.
