Abstract: The present inventors newly discovered that even if an antigen-binding molecule inhibits in vitro some of the physiological activities of an antigen having two or more physiological activities without inhibiting the remaining physiological activities, the molecule can promote elimination of the antigen from blood (from serum or plasma) and as a result reduce the physiological activities in vivo, when the antigen-binding molecule is conferred with the properties: (i) of binding to human FcRn under an acidic pH range condition; (ii) of binding under a neutral pH range condition to human Fc receptor stronger than native human IgG, and (iii) that its antigen-binding activity alters according to the ion concentration.

Abstract: The present inventors discovered that by forming a large immune complex comprising antigens containing two or more antigenic binding units (epitopes) and two or more antigen-binding molecules (for example, antibodies), elimination from the plasma of the antigens containing two or more antigenic binding units can be accelerated. Moreover, they found that by using this characteristic and by further using antigen-binding molecules having an ion-dependent antigen-binding activity, elimination of the antigens can further be accelerated and the above problem can be solved.

Abstract: An objective of the present invention is to provide methods of producing a cyclic organic compound using a continuous stirred tank reactor(s) (CSTR), the methods being capable of achieving excellent impurity-suppressing effects (quality improvement), reduction in reaction-tank size, continuous production, and such. The present inventors conducted studies on cyclization reactions using a CSTR(s), which had not been conventionally used for cyclization reactions for cyclic compounds. As a result, the inventors have found that the present methods can achieve excellent impurity-suppressing effects (quality improvement), reduction in reaction-tank size, continuous production, and such, as compared with conventional cyclization methods.

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.
