CD73 is an enzyme in the tumor microenvironment that produces adenosine, a powerful inhibitor of immune function in tumors. CD73 is expressed across a wide range of tumor types and tumor infiltrating leukocytes. Expression of CD73 often correlates with poor prognosis in patients with cancer. Blockade of adenosine production by CD73 inhibition is expected to reverse immunosuppression in the tumor microenvironment and enhance the immune system’s ability to fight the cancer. CB-708 is an orally bioavailable small molecule inhibitor of CD73.
