Durvalumab (MEDI 4736) is an humanized anti-PD-L1 monoclonal antibody, it completely blocks the binding of PD-L1 to both PD-1 and CD80, with IC50s of 0.1 and 0.04 nM, respectively. Durvalumab inhibits tumor growth in mouse xenograft models of human melanoma (A375) and pancreatic (HPAC) tumour cell lines, via a T-cell-mediated mechanism. Durvalumab (5-0.01 mg/kg for NOD/SCID mice with HPAC tumor; 5-0.1 mg/kg for NOD/SCID mice with A375 tumor; administration i.p.; twice per week; for 3 weeks) significantly inhibits the tumor growth of both HPAC and A375 xenografts compared with an isotype-matched control antibody.
Durvalumab was inactive against the mPD-L1.

| PD-1/PD-L1-IN-9
PD-1/PD-L1-IN-9 is a potent and orally active inhibitor of PD-1/PD-L1 interaction, with an IC50 of 3.8 nM. PD-1/PD-L1-IN-9 can enhance the killing activity of tumor cells by immune cells. PD-1/PD-L1-IN-9 also exhibits significant in vivo antitumor activity in a CT26 mouse model. |

| SL-279252
SL-279252 (PD1-Fc-OX40L) is a hexameric, bi-functional fusion protein with an ECD of PD-1 (70 pM affinity to PD-L1) linked to the ECD of OX40L (324 pM affinity for OX40) through an Fc linker. SL-279252 exhibited linear PK at doses up to 3.0 mg/kg, and a greater than proportional increase in AUC was observed at 6.0 mg/kg suggesting potential receptor saturation. The preliminary half-life is approximately 23 hours. |
| Rosnilimab
Rosnilimab is a novel PD-1 checkpoint agonist antibody that reduces overactive T cell inflammation. Rosnilimab optimizes PD-1+ T cell inhibitory signaling by enabling tight immune synapse formation. Rosnilimab restores immune balance bringing T cell composition to a less activated state. |
