The information provided to this Item 2.02 shall not be deemed
filed for purposes of Section 18 of the Securities Exchange Act
of 1934 (the Exchange Act) or otherwise subject to the
liabilities of that section, and shall not be incorporated by
reference into any filing or other document filed by the Company
to the Exchange Act or the Securities Act of 1933, as amended

provided to this Item 2.02 shall instead be deemed furnished.

to a request from CONSOB, the Italian securities regulatory
authority, CTI BioPharma Corp. (the Company) issued a press
release in Italy on May 26, 2017 providing certain requested
financial information for the month ended April 30, 2017 and
other information (the Monthly Italian Press Release). An English
translation of the Monthly Italian Press Release is attached as
Exhibit 99.1 and incorporated by reference herein. The financial
information contained in the Monthly Italian Press Release was
prepared at the instruction of CONSOB to Section 114, paragraph
5, of the Italian Legislative Decree no. 58/98. In communications
with CONSOB about its request that certain estimated and
unaudited financial information be disclosed by the Company, the
Company advised CONSOB that the information is not otherwise
required to be disclosed in the United States by public companies
under the U.S. securities laws. The Company further advised
CONSOB that any such financial information has not been reviewed
or audited by the Companys independent auditors as such reviews
only occur on a quarterly basis in connection with the
requirements of quarterly reports on Form 10-Q filed with the
U.S. Securities and Exchange Commission (the SEC), which reports
are prepared for the first three quarters of the year, and in
connection with the annual audit of the Companys year-end
financial statements, which is included in the Companys annual
reports on Form 10-K filed with the SEC. The Company further
advised CONSOB that any such financial information could not be
prepared in accordance with U.S. Generally Accepted Accounting
Principles (U.S. GAAP), as promulgated by the Financial
Accounting Standards Board.

In addition, the financial information contained in the Monthly
Italian Press Release does not conform to U.S. GAAP because the
Company has not concluded its consideration of authoritative
literature and guidelines. Accordingly, the data presented in the
information should not be relied on for investment purposes.
Moreover, the information may deviate from values as reported in
accordance with U.S. GAAP in the Companys reviewed quarterly
financial statements and audited year-end financial statements.

Further, the information contained in the Monthly Italian Press
Release may not be consistent with quarterly or annual financial
information presented in accordance with U.S. GAAP. This
information is being provided solely at the instruction of
CONSOB, is not used by management to evaluate the Companys
operating performance and is not presented as or intended to be
an alternative to U.S. GAAP financial information. The Company is
unable to reconcile this information to the most directly
comparable U.S. GAAP financial measures, because no such
comparable U.S. GAAP financial measures exist or are available at
the time as the Companys year-end review and audit process has
not yet been completed.

Investors are urged to refer to the Companys financial statements
prepared in accordance with U.S. GAAP and the risk factors listed
or described from time to time in the Companys filings with the
SEC including, without limitation, the Companys filings on Forms
10-K, 10-Q, and 8-K.
