Fibrozumab: A bispecific antibody with triple mechanism of action

Targeting:

Drug-Resistant Cancer Cells

Activated Fibroblasts

Angiogenic Endothelial Cells



Same mechanism, additional therapeutic opportunities

ONCOLOGY

Pancreatic cancer stroma

Disassembles CAF-built fibrotic matrix in vitro and in vivo; reduces stromal stiffness and reverses fibrosis hallmarks.

✓ Selective for disease matrix
LUNG FIBROSIS

Lung fibrosis

Blocks fibronectin and collagen assembly by fibroblasts from IPF patients while sparing physiological matrix in healthy fibroblasts.

✓ Spares normal fibroblast matrix
LIVER FIBROSIS

Liver fibrosis

Reduces fibrotic gene expression in human liver spheroids stimulated with a fibrotic cocktail; consistent with hepatic stellate cell biology.

✓ Validated in human liver model

How can Fibrozumab target cancer and fibrosis?

Blocking the same targets on multiple cell types involved in drug resistance, cancer progression, and fibrosis:

Targeting functional complex of cancer cells:

Adjuvant PDAC after curative-intent resection.

An essential combination partner for resistance-prone targeted therapy.

Targeting fibrotic cells:

To disrupt tumor fibrosis by targeting cancer-associated fibroblast production of fibronectin.

Targeting angiogenic endothelial cells:

To suppress tumor-associated angiogenesis.
