This disclosure provides a multimeric binding molecule, e.g., an IgM, IgM-like, IgA, or IgA-like binding molecule, e.g., an antibody with enhanced selectivity for cells expressing a target antigen at high density, e.g., tumor cells. Enhanced selectivity can be achieved, e.g., through modulation of binding affinity for the target antigen and/or through adjusting avidity via multimeric antigen binding.

The present invention relates to methods of treating a B-cell proliferative disorder by administering an anti-CD20/anti-CD3 bispecific antibody, and methods for reduction of adverse effects in response to the administration of the anti-CD20/anti-CD3 bispecific antibody. The present invention further relates to combination treatment methods of treating a B-cell proliferative disorder.

The present invention is directed to a combination therapy involving a type II anti-CD20 antibody and a selective Bcl-2 inhibitor for the treatment of a patient suffering from cancer, particularly, a CD20-expressing cancer.

Compounds having cytotoxic and/or anti-mitotic activity are disclosed. Methods associated with preparation and use of such compounds, as well as pharmaceutical compositions comprising such compounds, are also disclosed. Also disclosed are compositions having the structure: (T)-(L)-(D), wherein (T) is a targeting moiety, (L) is an optional linker, and (D) is a compound having cytotoxic and/or anti-mitotic activity.

The present invention provides a basal cell culture medium and a feed medium with novel amino acid ratios and/or iron choline citrate as iron carrier that result in improved performance of mammalian cell culture processes, such as CHO cultivation and protein production processes, in particular in increased product titer (e.g. of monoclonal antibodies). Also provided are methods for culturing mammalian cells and producing a protein of interest using said basal cell culture medium and optionally feed medium. The invention also provides for a medium platform that comprises (i) the basal cell culture medium and (ii) the feed medium.

Described herein are methods, formulations and kits for treating a patient with triple-negative breast cancer with nanoparticle complexes comprising a carrier protein (e.g., albumin), paclitaxel and a binding agent specific for a target antigen expressed by the cells (e.g., an anti-VEGF antibody).

The present invention, in the field of bioengineering and biotechnology, relates to a method for preparing a recombinant antibody with a unique glycan profile produced by a genome-edited CHO host cell. Specifically, according to a method of the present invention, the TALEN technology is used to edit the FUT8 gene in CHO cells that have been adapted for serum-free suspension growth. The edited CHO host cells can produce recombinant antibodies with a unique glycan profile. The unique glycan profile can be characterized by non-fucosylated N-linked oligosaccharide chains of the antibodies, extremely low N-glycosylation heterogeneity and uniform carbohydrate chains. The antibody prepared by the method of the invention exhibit significantly increased ADCC and greater stability.

Administration regimens for therapeutic proteins (e.g., T cell-activating bispecific antibodies) that mitigate cytokine release syndrome and infusion-related reaction are disclosed. The methods employ initial fractional dosing with optional administration of additional agents such as steroids or cytokine antagonists that are discontinued with maximal weekly dosing over the course of the dosing regimen.

Provided herein are compositions, methods and uses involving antibodies that specifically bind to signal regulatory protein-α (SIRPα) and modulate the activity of SIRPα.

The present invention relates to human IgG Fc domain variants with improved effector function and uses thereof.
