生物活性:
Panobacumab (KBPA101) is a fully human IgM/κ monoclonal antibody generated by immortalizing human B lymphocytes against the LPS O polysaccharide of serotype O11 of P. aeruginosa.

体内研究:
Panobacumab (KBPA101) (1-4 mg/kg; i.v.; once) protects mice from systemic infection with P. aeruginosa serotype O11 in a murine burn wound model.Panobacumab (KBPA101) (0.005-0.4 mg/kg; i.v.; once) protects mice from local lung infection with P. aeruginosa serotype O11 in an acute lung infection model.Animal Model:Female NMRI mice, murine burn wound model
Dosage:1, 2, or 4 mg/kg
Administration:Intravenous injection, single dose
Result:Significantly reduced mortality compared to untreated control animals administered either immediately or 4 h postchallenge.
Animal Model:BALB/c mice, acute lung infection model
Dosage:0.005 to 0.4 mg/kg
Administration:Intravenous injection, single dose
Result:Led to rapid clearance of P. aeruginosa from the lung, completely cleared systemic P. aeruginosa from the spleen, whereas live bacteria were still present in untreated mice at 48 h postchallenge, showed milder macroscopic lung pathology at 6 and 24 h after infection.

体外研究:
Panobacumab (KBPA101) strongly binds to 18 of 20 clinical O11 isolates, functional avidity of KBPA101 to O11 LPS determined by inhibition ELISA is 5.81×107 M-1± 2.8×107 M-1.Panobacumab (KBPA101) (0.0001-100 ng/mL; 2 h) specifically mediates complement-dependent opsonophagocytosis of P. aeruginosa serotype O11 with an IC50 of 0.16 ng/mL.Panobacumab (KBPA101) (0.1-10 ng/mL) shows direct complement-dependent killing of P. aeruginosa serotype O11 cells in a dose-dependent manner.
