生物活性:
Xentuzumab (Anti-Human IGF1 and IGF2 Recombinant Antibody; BI836845) is a recombinant a human monoclonal antibody that targets IGF ligands IGF1 and IGF2. Xentuzumab inhibits both of IGF1 and IGF2 growth-promoting signalling and suppresses AKT activation.

体内研究:
Xentuzumab (200 mg/kg i.p., once weekly for 10 weeks) in inhibits tumor growth in LuCaP 96CR patient-derived xenograft model in mice.Animal Model:Fox Chase CB17 severe combined immunodeficiency (SCID; CB17/lcr-Prkdc scid/lcrlcoCrl) male mice with LuCaP 96CR cell (s.c.)
Dosage:200 mg/kg
Administration:Intraperitoneal injection; once weekly for 10 weeks; sacrificed 6 hours after the last dose
Result:Resulted in significant reductions in tumor volume.

体外研究:
Xentuzumab (0.01-1 mM; 96 h) inhibits IGF type 1 receptor signaling and (0.1 μM; 48 h) AKT serine/threonine kinase (AKT) phosphorylation in VCaP, DuCaP, and MDA PCa 2b cell in a dose-dependent manner.Xentuzumab (0.01-1 mM; 5-10 d) losses of antiproliferative activity against PTEN-null LNCaP or PC-3 cells when PTEN knockdown.Xentuzumab (1 μM; 24-72 h) arrests cell cycle at sub-G1 phase and induces apoptosis in VCaP cells.
