NPX887
Clinical-stage oncology biologicA tri-functional B7-H7-directed checkpoint inhibitor in Phase 1 clinical trials that blocks the B7-H7/KIR3DL3 interaction, enhances TMIGD2 co-stimulation, and drives antibody-dependent cellular cytotoxicity.
- Three mechanisms in one antibody: checkpoint blockade, co-stimulation, and ADCC
- Targets the B7-H7 (HHLA2) axis rather than PD-1/PD-L1
- Biomarker-guided patient selection for B7-H7-positive tumors
- Currently in Phase 1 clinical development
