Item 8.01 Other Events.

CTI BioPharma Corp (the “Company”) will hold its annual meeting of shareholders (the “2016 Annual Meeting”) on April 29, 2016, at 10:00 a.m., Pacific time, at the Company’s headquarters, located at 3101 Western Avenue, Suite 600, Seattle, Washington 98121. The record date for the Annual Meeting has been set as the close of business on February 26, 2016.

Because the date of the 2016 Annual Meeting has been changed by more than 30 days from the anniversary of the Company’s 2015 annual meeting of shareholders, the deadline for the submission of proposals by shareholders for inclusion in the Company’s proxy materials relating to the 2016 Annual Meeting in accordance with Rule 14a-8 under the Securities Exchange Act of 1934, as amended, will be the close of business on January 28, 2016, which the Company believes is a reasonable time before it expects to begin to print and send its proxy materials. Any proposal received after such date will be considered untimely.

In accordance with the Company’s Amended and Restated Bylaws (the “Bylaws”), shareholders who intend to nominate a person for election as a director or submit a proposal regarding any other matter of business at the 2016 Annual Meeting must deliver written notice of any proposed business or nomination to the Company’s Secretary, at the address specified above, no later than the close of business on January 18, 2016 (which is the tenth day following the date of filing of this Current Report on Form 8-K, which provides the first public announcement of the date of the 2016 Annual Meeting). Any notice of proposed business or nomination must comply with the specific requirements set forth in the Company’s Bylaws in order to be considered at the 2016 Annual Meeting.
