Antibody Substituting for Function of Blood Coagulation Factor VIII

Номер: US20120237517A1
Принадлежит: Chugai Pharmaceutical Co Ltd

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.

COMPOSITIONS AND METHODS FEATURING IL-6 AND IL-21 ANTAGONISTS

Номер: US20130224109A1

The present invention features compositions for inhibiting both the IL-6 and the IL-21 pathways and methods of making and using such compositions. Our work to date indicates the importance of the redundancy of IL-6 and IL-21 to perform certain crucial functions. The pathways can be inhibited by inhibiting the ligands (i.e., IL-6 and IL-21) and/or their respective receptors (i.e., the IL-6 receptor and IL-21 receptor). Alternatively, or in addition, upstream and downstream effectors in the IL-6 and IL-21 pathways can be blocked. The agents used can be antibody or antibody-based proteins or peptides including circulating receptors, optionally coupled to an immunoglobulin or a portion thereof (e.g., the Fc region). Also provided are methods for using the compositions, for example, in organ transplantation, tissue grafting, or autoimmune disorders. 1.

Номер: US20190000989A1
Принадлежит:

The present invention is directed to a platform for new bispecific targeting agents using liposomes or nanoparticles as linkers. The bispecific targeting agent can bind two different cell types, each via a separate targeting moiety. Said targeting agents can be used to induce specific biological effects in the cells such as cell proliferation or cell activation which can be used in some instances to destroy the other bound cells. Any cell that can be targeted can be subject to targeting. For example, the cell types that may be recruited by the bispecific targeting agent may be both human or one of the cells may be human and the other an infected cell or it can be an infectious agent. The platform is based on an empty nanoparticle or liposome conjugated to two or more targeting moieties, bound to the nanoparticle/liposome at defined ratios that may be other than 1:1. Such, compositions provide for specific binding to each cell type. This bispecific targeting agent can further be linked to growth factors or cytokines to further potentiate the effect of the bispecific targeting agent as a therapeutic or to exert a specific biologic effect on one or both cells being targeted. 138-.

ANTIBODY SUBSTITUTING FOR FUNCTION OF BLOOD COAGULATION FACTOR VIII

Номер: US20180002443A1

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. 228.-.
