CTI BioPharma or the Company) (NASDAQ and MTA: CTIC) today announced that the United Kingdom's National Cancer Research Institute (NCRI) Haematological Oncology Clinical Studies Group has chosen to advance tosedostat, the Company's investigative oral
aminopeptidase inhibitor, to the second stage of a randomized clinical trial of low-dose cytarabine plus or minus tosedostat in older patients with Acute Myeloid Leukemia (AML) or high risk Myelodysplastic Syndrome (MDS).
This modification protects it against
aminopeptidase degradation, and improves receptor activation and signal transduction in vitro (11).

Tosedostat is a first-in-class selective inhibitor of
aminopeptidases, which are required by tumor cells to provide amino acids necessary for growth and tumor cell survival.
