Forward-Looking Statements This press release includes forward-looking statements within the meaning of the Safe Harbor provisions of the Private Securities Litigation Reform Act of 1995. Such statements are subject to a number of risks and uncertainties, the outcome of which could materially and/or adversely affect actual future results and the trading price of CTI's securities. Such statements include, but are not limited to, statements regarding expectations with respect to the development of the Company and its product and product candidate portfolio, NICE's processes, the expected timing thereof and whether NICE will consider an 'enhanced' patient access scheme to demonstrate the cost effectiveness of pixantrone for use by the NHS in the UK, pricing arrangements and the cost-effectiveness and availability of PIXUVRI to patients in the UK. Risks that contribute to the uncertain nature of the forward-looking statements include, among others, risks that NICE does not consider PIXUVRI to be cost-effective or clinically effective over and above current alternative treatments as a result of uncertainties relating to failure to recruit the planned number of patients, use of a primary endpoint of complete or unconfirmed response to treatment rather than a primary end point of overall survival or progression-free survival, differences between the PIX301 trial population and UK clinical practice and the absence of statistically significant differences in overall survival between treatment arms in the PIX301 trial or other reasons, risks associated with the biopharmaceutical industry in general and with CTI and its product and product candidate portfolio in particular including, among others, risks associated with the following: that CTI cannot predict or guarantee the pace or geography of enrollment of its clinical trials, that CTI cannot predict or guarantee the outcome of preclinical and clinical studies, that CTI may not obtain reimbursement for PIXUVRI in certain markets in the European Union as planned, that the conditional marketing authorization for PIXUVRI may not be renewed, that the second Phase 3 clinical trial of pacritinib will not occur as planned, that CTI may not obtain favorable determinations by other regulatory, patent and administrative governmental authorities, that CTI may experience delays in the commencement of preclinical and clinical studies, risks related to the costs of developing, producing and selling PIXUVRI, pacritinib, and CTI's other product candidates, and other risks, including, without limitation, competitive factors, technological developments, that CTI's operating expenses continue to exceed its net revenues, that CTI may not be able to sustain its current cost controls or further reduce its operating expenses, that CTI may not achieve previously announced goals and objectives as or when projected, that CTI's average net operating burn rate may increase, that CTI will continue to need to raise capital to fund its operating expenses, but may not be able to raise sufficient amounts to fund its continued operation as well as other risks listed or described from time to time in CTI's most recent filings with the Securities and Exchange Commission on Forms 10-K, 10-Q and 8-K.
