Cabiralizumab
Based on 1 Customer Validation
Cabiralizumab (FPA 008) is an anti-CSF1R monoclonal antibody (MAb). Cabiralizumab enhances T cell infiltration and antitumor T cell immune responses. Cabiralizumab inhibits the activation of osteoclasts and blocks bone destruction, and can be used in the research of rheumatoid arthritis (RA). Cabiralizumab can combine with Nivolumab (HY-P9903) for lung cancer research.

Biological Activity
Human IgG4 kappa
Human
CSF1R/M-CSFR/CD115
Cabiralizumab (7 days) disrupts circulating tumor cells (CTC) cluster formation and increases CTC apoptosis in pancreatic ductal adenocarcinoma (PDAC) patient portal blood mononuclear cells (PortalBMC) unsorted samples[4].
Cabiralizumab (7 days) can re-activate PDAC patient T cells (CD3+CD25+CTLA4-PD1L1-) and increases IFNγproduction in PortalBMC[4].

Animal Model:C57Bl6 male mice model (YUMMER1.7 (UV irradiated derivative of YUMM1.7 carrying a higher number of somatic mutations) or YUMM1.7 (BrafV600E /Pten−/−, Cdkn2a−/−) cells were subcutaneously injected into the left flank) (8-9 week old)[3]
-
Dosage:200, 400 μg
-
Administration:Intraperitoneal injection (i.p.); twice a week for 5 times
-
Result:In the group treated with higher dose αCSF1R, 55% of mice (11/20) reached endpoint, whereas mice treated with lower dose αCSF1R fared better with 25% (5/20) reaching the endpoint in YUMMER1.7 mice model.
Lower αCSF1R dose resulted in improved survival compared to the higher αCSF1R dose in YUMMER1.7 mice model.
Treatment with both lower and higher anti-CSF1R dose delayed the tumor growth, but all tumors eventually grew out to endpoint in YUMM1.7 mice model.

Flow cytometric analysis of 1.5X106 THP-1 cells labeling Cabiralizumab (HY-P99259, red). Cells were fixed with 4% paraformaldehyde. Then stained with the primary antibody at 1/200 dilution for an hour at 4℃. Goat Anti-Human IgG H&L (AF488) (HY-P83776) was used as the secondary antibody at 1/1,000 dilution for 30 minutes at 4℃. Human IgG4 kappa (HY-P99003, blue) was used as the isotype control.
