Reslizumab

Research use only, not for human use.

Reslizumab (Sch 55700) is a humanized immunoglobulin G (IgG)4 κ monoclonal antibody that binds to human interleukin 5, thereby decreasing eosinophil production and survival.

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.

Reslizumab (Sch 55700) (0-10 nM, 48 h) inhibits IL-5-dependent cell proliferation, with an IC50 value of approximately 91.1pM.Cell Proliferation Assay Cell Line:Human erythroleukemic TF-1 cell line Concentration:0-10 nM Incubation Time:48 h Result:Showed antiproliferative activity with an IC50 of 91.1 pM.

Reslizumab (Sch 55700) (0-10 mg/kg; i.p. or i.m.) inhibits pulmonary eosinophilia in a dose-dependent manner in allergic mice.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.Reslizumab (0.1-1 mg/kg; i.p.) blocks the pulmonary eosinophilia and neutrophilia caused by tracheal injection of hIL-5 in guinea pigs.Reslizumab (0.3 mg/kg; i.v.) blocks the pulmonary eosinophilia caused by antigen challenge for up to six months in allergic cynomolgus monkeys.Animal Model:Male B6D2F1/J mice weighing 20?25 g, sensitized by an intraperitoneal injection of 0.5 ml of alum-precipitated antigen (8 μg of ovalbumin (OVA) adsorbed to 2 mg of aluminum hydroxide gel in saline vehicle) Dosage:0?10 mg/kg Administration:Intraperitoneal or intramuscular injection (For studies involving i.p. dose-response and i.m. evaluation, the antibody was given 2 h before OVA challenge. For experiments involving duration of activity, the antibody was given at times of 2 h or 4, 6, 8 or 12 weeks before antigen challenge.)Result:Inhibited the influx of eosinophils into the lungs for a long time (up to 8 weeks after administration of 10 mg/kg and for up to 4 weeks after administration of 2 mg/kg. Demonstrated an anti-inflammatory activity that was additive to that of oral Prednisolone (HY-17463).
