INCB-086550 (INCB-086550) is a novel, investigational and selective small molecule PD-1/PD-L1 inhibitor based on the biphenyl scaffold core structure first disclosed by BMS company. It acts by blocking the activity of the programmed cell death protein 1 (PD-1) inhibitory receptor with therapeutic antibodies against either the ligand (PD-L1) or PD-1 itself has proven to be an effective treatment modality for multiple cancers. Contrasting with antibodies, small molecules could demonstrate increased tissue penetration, distinct pharmacology, and potentially enhanced antitumor activity.
| ln Vitro |
For pleural effusion cells, INCB086550 (0.1–10,000 nM, 20 hours) has no discernible toxicity [1]. PD-L1 on the cell surface dimerizes when exposed to NCB086550 (1 µmol/L) for 24 hours, which causes internalization [1].
|
|---|---|
| ln Vivo |
In the MDA-MB-231 mouse model, INCB086550 (15, 200 mg/kg, active region, once or twice) suppresses over 90% of occupied cell surface PD-L1 [1]. The MC38 huPD-L1 tumor model is inhibited in its growth by INCB086550 (2, 20, or 200 mg/kg, twice daily in mouse model) [1].

Cell viability assay [1]
Cell Types: pleural effusion cells Tested Concentrations: 0.1-10000 nM Incubation Duration: 20 hrs (hours) Experimental Results: No obvious toxicity to pleural effusion cells. Immunofluorescence[1] Cell Types: CHO PD-L1 Cell Tested Concentrations: 1 µmol/L Incubation Duration: 24 hrs (hours) Experimental Results: Overall PD-L1 reduction in CHO PD-L1 cells. Demonstrates rapid internalization of PD-L1, reaching maximum in approximately 4 hrs (hours). |
| Animal Protocol |
Animal/Disease Models: Mice bearing MDA-MB-231 xenografts [1]
Doses: 15, 200 mg/kg Route of Administration: po (oral gavage) Experimental Results: MDA-MB-231 unoccupied tumors after 24 hrs (hrs (hours)) Cell surface PD-L1 is diminished. Animal/Disease Models: C57BL/6 and NSG mice with established MC38-huPD-L1 tumors [1] Doses: 2, 20 or 200 mg/kg Route of Administration: po (oral gavage) Experimental Results: Induction of PD- L1 dose-dependent reduction was achieved using the antibody clone MIH1 that binds to PD-1. At the 200 mg/kg dose, cell surface occupied by PD-L1 was diminished by >90%. |

| Additional Infomation |
PD-L1 Inhibitor INCB086550 is an orally available, small molecule inhibitor of the immunosuppressive ligand, programmed cell death-1 ligand 1 (PD-L1; cluster of differentiation 274; CD274) with potential immune checkpoint inhibitory and antineoplastic activities. Upon administration, PD-L1 inhibitor INCB086550 specifically targets PD-L1 expressed on tumor cells preventing the binding and subsequent activation of its receptor, programmed cell death 1 (PD-1; PDCD1; CD279; programmed death-1). This reverses T-cell inactivation caused by PD-L1/PD-1 signaling, increases T-cell expansion and enhances the cytotoxic T-lymphocyte (CTL)-mediated anti-tumor immune response against PD-L1-expressing tumor cells. PD-L1, a transmembrane protein expressed on activated T-cells, is overexpressed in some cancer types and plays a significant role in immune evasion by tumor cells.
