  • Publication number: 20190359728
    Abstract: The present inventors produced a variety of bispecific antibodies that specifically bind to both F. IX/F. IXa and F. X, and functionally substitute for F. VIIIa, i.e., have a cofactor function to promote F. X activation via F. IXa. Among these antibodies, the antibody A44/B26 reduced coagulation time by 50 seconds or more as compared to that observed when the antibody was not added. The present inventors produced a commonly shared L chain antibody from this antibody using L chains of A44, and showed that A44L can be used as commonly shared L chains, although the activity of the resulting antibody is reduced compared to the original antibody (A44HL-B26HL). Further, with appropriate CDR shuffling, the present inventors successfully produced highly active multispecific antibodies that functionally substitute for coagulation factor VIII.

  • Patent number: 10389279
    Abstract: To provide a controller of a rotary electric machine which can prevent the vibration torque component to be outputted by the rotary electric machine from being upper-limited by the maximum output torque of the rotary electric machine. A controller of a rotary electric machine decreases an amplitude of the vibration torque command value so that a vibration maximum value obtained by adding an amplitude of a vibration torque command value to a basic torque command value becomes less than or equal to an upper limit command value; and calculates a value obtained by upper-limiting an addition torque command value, which is obtained by adding the vibration torque command value to the basic torque command value, by the upper limit command value, as a final torque command value.
