Reslizumab (Sch 55700) is humanized monoclonal antibodies that target interleukin-5 (IL-5) for the treatment of eosinophilic asthma. Reslizumab is effective in neutralizing the function of IL-5. Reslizumab has high binding affinity for human IL-5, with KD values of 109 pM and 4.3 pM in the the Biacore surface plasmon resonance and Kinetic Exclusion Assay, respectively[1][2].
Reslizumab (Sch 55700) (0-10 nM, 48 h) inhibits IL-5-dependent cell proliferation, with an IC50 value of approximately 91.1pM[1].
Reslizumab (Sch 55700) (0-10 mg/kg; i.p. or i.m.) inhibits pulmonary eosinophilia in a dose-dependent manner in allergic mice[3].
Reslizumab (0.03-30 mg/kg; i.p.) inhibits both the pulmonary eosinophilia and airway hyperresponsiveness, and at 30 mg/kg, i.p. inhibits allergic, but not histamine-induced bronchoconstriction in allergic guinea pigs[3].
Reslizumab (0.1-1 mg/kg; i.p.) blocks the pulmonary eosinophilia and neutrophilia caused by tracheal injection of hIL-5 in guinea pigs[3].
Reslizumab (0.3 mg/kg; i.v.) blocks the pulmonary eosinophilia caused by antigen challenge for up to six months in allergic cynomolgus monkeys[3].
