Definition

An orally bioavailable inhibitor of the T-cell specific tyrosine-protein phosphatase non-receptor type 2 (PTPN2), with potential immunomodulating and antineoplastic activities. Upon oral administration, PTPN2 inhibitor ABBV-CLS-484 specifically targets and binds to PTPN2. This prevents PTPN2-mediated signal transduction pathways and may activate anti-tumor T-cell immune responses. It may also sensitize tumor cells to immunotherapeutics. PTPN2 negatively regulates TCR and cytokine signaling needed for T-cell function, homeostasis and differentiation.
