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.

The present disclosure relates to, inter alia, antibodies, or antigen-binding fragments thereof, that bind to C5a and to use of the antibodies in methods for treating or preventing complement-associated disorders such as, but not limited to, atypical hemolytic uremic syndrome, age-related macular degeneration, rheumatoid arthritis, sepsis, severe burn, antiphospho lipid syndrome, asthma, lupus nephritis, Goodpasture's syndrome, and chronic obstructive pulmonary disease.

The present invention provides a method for manipulating the fucosylated glycan content on a recombinant protein.

An object of the present invention is to provide an antibody composition, which exhibits an effector function more specifically for a target cell coexpressing two types of antigens that are different from each other and damages the target cell, and also can maintain affinity for the individual target antigens sufficiently high. The present invention relates to an antibody composition against a first antigen and a second antigen that are different from each other, including a first IgG half-molecule and a second IgG half-molecule and relates to the first IgG half-molecule and the second IgG half-molecule constituting the antibody composition.

The present invention relates to antibodies that bind to human HLA-G, multispecific antibodies thereof, their preparation, formulations, and methods of using the same.

Materials and methods for using polypeptides containing fragments and variants of the antibody(ies) or portion(s) thereof that bind CD25 to treat cancer alone or in combination with other anti-neoplastic agents.

The present invention provides novel anti-HIV antibodies with improved therapeutic properties, related pharmaceutical compositions, and methods of use thereof.

The present invention relates to anti-CLL-1 antibodies including anti-CLL-1 antibodies comprising a CLL-1 binding domain and a CD3 binding domain (e.g., anti-CLL-1/CD3 T cell dependent bispecific (TDB) antibody) and methods of using the same.

Disclosed is an antibody that specifically binds CD70, or an antigen binding portion thereof. A nucleic acid molecule encoding the antibody or antigen binding portion thereof, an expression vector and a host cell comprising the nucleic acid molecule, a method for expressing the antibody or antigen binding portion thereof, and a method for treating a disease associated with CD70 signaling using the antibody or antigen binding portion thereof are also provided.

The invention provides methods of dosing for the treatment of cancers, such as B cell proliferative disorders, with anti-cluster of differentiation 20 (CD20)/anti-cluster of differentiation 3 (CD3) bispecific antibodies.
