Ivuxolimab
Based on 1 Customer Validation
Ivuxolimab is a fully human IgG2 agonist targeting OX40 (CD134), which selectively binds to the OX40 receptor on the surface of activated CD4+ and CD8+ T cells without inducing antibody-dependent cytotoxicity. Ivuxolimab can promote T cell proliferation, survival and cytokine (such as IFN-γ, IL-2) secretion, inhibit regulatory T cell function, and enhance anti-tumor immune response. Ivuxolimab can be used in the study of melanoma, hepatocellular carcinoma, head and neck squamous cell carcinoma, etc.

IL-2 |
Ivuxolimab (0.02-2 μg/mL; 6 days) can significantly promote the proliferation of T cells stimulated by anti-CD3/CD28 in the primary CD4+ T cell proliferation experiment, and the dual-epitope antibody (such as 11D4-OX.F2) is more active than the single-epitope antibody[2].

Cell Line:Primary human CD4+ T cells
-
Concentration:0.02, 0.2, 2 μg/mL

-
Animal Model:Female Balb/c mice (6-8 weeks old, 18-20 g) with subcutaneous CT26 tumor xenografts[2]
-
Dosage:10 mg/kg Ivuxolimab-derived biepitopic antibody (11D4-OX.F2)
-
Administration:Intravenous injection twice weekly for 3 weeks, starting 24 hours after tumor cell inoculation
-
Result:Significantly reduced tumor growth compared to isotype control-treated mice, with no significant change in body weight.
Histological analysis showed increased infiltration of CD8+ T cells and reduced regulatory T cell (FoxP3+) density in tumor tissues, indicating enhanced antitumor immune responses.

Immobilized OX40/TNFRSF4 Protein, Human (HEK293, His, HY-P7394) can bind Ivuxolimab. The EC50 for this effect is 20.45 ng/mL. -
Flow cytometric analysis of 1X106 500 ng/mL anti-CD3 and 500 ng/mL ant-CD28 co-stimulated Jurkat cells(24h) with Ivuxolimab (HY-P99159, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Alexa Fluor 488-conjugated AffiniPure Goat Anti-Human IgG H&L (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG2 kappa (HY-P99002, blue) was used as the isotype control, cells without incubation with primary antibody were used as the unlabeled control (black).
