About CCX559
CCX559 is a highly potent orally administered small molecule PD-L1 checkpoint inhibitor. Preclinical characterization has demonstrated that CCX559 blocks binding to PD-1 and CD80, and prevents PD-L1 inhibition of T cell activation. CCX559, when orally administered in animal models, demonstrated anti-tumor efficacy, including the ability to induce complete responses.
The PD-L1/PD-1 interaction is one of the major immune checkpoints that limits the ability of effector T cells to destroy cancer cells. As a potential next generation therapy, an orally administered small molecule inhibitor of PD-L1 could have advantageous properties compared to approved monoclonal antibodies, such as better penetration into solid tumors, reduced immunogenicity, lack of Fc-mediated side effects and convenience of oral administration.
During 2021, ChemoCentryx initiated a first-in-human Phase I dose escalation study to evaluate the safety, tolerability, PK, and PD of CCX559 in patients with various types of advanced cancer. In early 2023, the Company plans to advance CCX559 into a Phase Ib/II clinical trial to measure anti-tumor effects of CCX559 more directly.

ChemoCentryx is also developing CCX559, a highly potent orally administered small molecule PD-L1 checkpoint inhibitor, for the treatment of patients with solid tumors. A Phase I dose escalation study for CCX559 is ongoing and ChemoCentryx plans to advance to a Phase Ib/II study in early 2023.
Additionally, ChemoCentryx has early-stage drug candidates that target chemoattractant receptors in other inflammatory and autoimmune diseases and in cancer. For more information about the Company visit www.ChemoCentryx.com.
