摘要:
The present inventors isolated clone BM095 from a human antibody phage library, which had a strong growth inhibitory activity in the IL-31-dependent Ba/F3 cell growth assay system. When administered to pruritus model mice, the anti-mouse NR10 neutralizing antibody exhibited a marked symptom-suppressing effect. Thus, it was revealed that anti-NR10 neutralizing antibodies are useful as therapeutic agents for pruritus.
摘要:
The present invention provides pharmaceutical compositions comprising second-generation molecules that are superior than TOCILIZUMAB, by altering the amino acid sequences of the variable and constant regions of TOCILIZUMAB, which is a humanized anti-IL-6 receptor IgG1 antibody, to enhance the antigen-neutralizing ability and increase the pharmacokinetics, so that the therapeutic effect is exerted with a less frequency of administration, and the immunogenicity, safety and physicochemical properties (stability and homogeneity) are improved. The present invention also provides methods for producing these pharmaceutical compositions. The present inventors have successfully generated second-generation molecules that are superior to TOCILIZUMAB by appropriately combining amino acid sequence alterations in the CDR domains, variable regions, and constant regions.
摘要:
In a non-limiting embodiment, there is provided a pharmaceutical composition for prevention and/or treatment of atopic dermatitis comprising an IL-31 antagonist as an active ingredient, wherein the IL-31 antagonist is repeatedly administered in equal amounts at the same dosing interval to a subject with or potentially with atopic dermatitis, at 0.1 to 1000 mg/body/1 day to 12 weeks, preferably at 0.1 to 1000 mg/body/2 weeks, 0.1 to 1000 mg/body/4 weeks, or 0.1 to 1000 mg/body/8 weeks.
