Panobacumab

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.

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[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^[1].
Panobacumab (KBPA101) (0.1-10 ng/mL) shows direct complement-dependent killing of P. aeruginosa serotype O11 cells in a dose-dependent manner^[1].

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^[1].
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^[1].
