Ezabenlimab Usage And Synthesis

Description

Ezabenlimab is a monoclonal antibody directed against the negative immunoregulatory human cell surface receptor programmed cell death protein 1 (PD-1; PDCD1), with immune checkpoint inhibitory and antineoplastic activities. Upon administration, ezabenlimab selectively binds to and blocks the activation of PD-1, an immunoglobulin (Ig) superfamily transmembrane protein, by its ligands programmed cell death ligand 1 (PD-L1), which is overexpressed on certain cancer cells, and programmed cell death ligand 2 (PD-L2), which is primarily expressed on antigen-presenting cells (APCs). This results in the activation of T-cells and T-cell-mediated immune responses against tumor cells. Activated PD-1 negatively regulates T-cell activation and plays a key role in in tumor evasion from host immunity.

Uses

Ezabenlimab (BI-754091) is an anti-PD-1 mAb with binding constant Kd value of 6 nM (CHO cells). Ezabenlimab blocks the interaction of PD-1 with PD-L1 and PD-L2. Ezabenlimab increases interferon-γ secretion in T cells, and inhibits tumor growth in vivo[1].

in vivo

Ezabenlimab (0.3-30 mg/kg; i.p.; single dose or twice per week or every 3 weeks) inhibits tumor progress and shows comparable anti-tumor activity in hPD-1 knock-in mouse model[1].

Animal Model:hPD-1 knock-in mouse model[1]
Dosage:0.3 mg/kg, 1 mg/kg, 3 mg/kg, 10 mg/kg, 30 mg/kg
Administration:Intraperitoneal injection; single dose or twice per week or every 3 weeks
Result:Showed tumor growth inhibition (TGI) at day 25 dose-dependently of 99%, 101%, 91%, 48%, and 44%, respectively.
