  • Publication number: 20200231688
    Abstract: 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.

  • Patent number: 10615079
    Abstract: A buried n-type region is provided in a surface layer portion of an n-type body layer of a Pch MOSFET. This makes it possible to lower the threshold voltage Vt. In a portion of the n-type body layer other than the buried n-type region, since an n-type impurity concentration can be kept relatively high, the threshold voltage Vt can be lowered while securing an on-breakdown voltage. Furthermore, since an accumulation region is configured by an n-type active layer, a partial high concentration portion is not formed in a p-type drift layer. Therefore, as in the case where the partial high concentration portion is generated in the p-type drift layer, a reduction in a breakdown voltage caused by an electric field concentration can be restricted from occurring with a distribution in which equipotential lines are concentrated.
