Glancy Prongay & Murray LLP (“GPM”) is investigating potential claims on behalf of investors of CTI BioPharma Corp.("CTI" or the "Company") (NASDAQ: CTIC) concerning the Company and its officers’ possible violations of federal securities laws.

On February 8, 2016, pre-market, CTI disclosed that it had been alerted by the U.S. Food and Drug Administration (FDA) that the FDA had placed a partial hold on clinical studies of CTI's primary product, pacritinib. The FDA has recommended that CTI amend its procedures for randomized studies to disallow crossover to pacritinib, provide specific notifications, adjust certain statements in both the investigator's brochure and informed consent documents and other actions.

Upon this news, CTI stock fell $0.62, or nearly 55%, to just $0.50 per share during intraday trading on February 8, 2016, thereby injuring investors.

If you purchased CTI securities, have information or would like to learn more about these claims, or have any questions concerning this announcement or your rights or interests with respect to these matters, please contact Lesley Portnoy, Esquire, of GPM, 1925 Century Park East, Suite 2100, Los Angeles, California 90067 at 310-201-9150, Toll-Free at 888-773-9224, by email to shareholders@glancylaw.com, or visit our website at http://www.glancylaw.com.
