The present invention relates to methods of modulating the mannose content of recombinant proteins.

The present invention provides an antibody or an antigen-binding fragment thereof with binding specificity for human interleukin-1 receptor accessory protein (IL1RAP) wherein the antibody or antigen-binding fragment is capable of inhibiting the binding of antibody ‘CAN04’ to human IL1RAP. The invention further provides the use of such antibodies or an antigen-binding fragments in the treatment and/or diagnosis of IL-1 associated diseases and conditions, including cancers such as acute myeloid leukemia and melanoma.

The present invention relates to anti-transferrin receptor antibodies and methods of their use.

Described herein are antibody formulations including a therapeutic antibody at a concentration of at least 20 mg/ml, methods for optimizing and producing such antibody formulations, and methods of using such antibody formulations. Antibody formulations including a therapeutic antibody at a concentration of at least about 20 mg/mL are described herein. For example, described are high concentration solutions and formulations of aglycosylated antibod(ies), methods of making such formulations, and methods for using such formulations. The described formulations, when solutions, exhibit reduced viscosity and good stability.

An aglycosylated humanized anti-Bb (AAfBb) antibody or antigen binding fragment thereof includes a modification at a conserved N-linked site in the CH2 domains of an Fc portion of the antibody or antigen binding fragment thereof.

The present invention describes antibodies that target CD19, wherein the antibodies comprise at least one modification relative to a parent antibody, wherein the modification alters affinity to an FcγR or alters effector function as compared to the parent antibody. Also disclosed are methods of using the antibodies of the invention.

The disclosure provides antibodies that are useful for, among other things, inhibiting terminal complement (e.g., the assembly and/or activity of the C5b-9 TCC) and C5a anaphylatoxin-mediated inflammation and, thus, treating complement-associated disorders. The antibodies have a number of improved properties relative to eculizumab, including, e.g., increased serum half-life in a human.

Provided herein are, inter alia, anti-CD73 antibodies and methods of using the same. The antibodies provided include amino acid substitution embodiments affecting the antibody glycosylation state. The antibodies provided herein are, inter alia, useful for the treatment of cancer and effective for inhibition of CD73 activity.

Provided are antibodies and antigen-binding fragments thereof that bind specifically to human complement factor C2 and are capable of inhibiting activation of the classical and lectin pathways of the complement system. The antibodies and antigen-binding fragment exhibit improved manufacturability, pharmacokinetics, and antigen sweeping. Also provided are pharmaceutical compositions comprising the antibodies and antigen-binding fragments, nucleic acids and vectors encoding the antibodies and antigen-binding fragments, host cells comprising the nucleic acids or vectors, and methods of making and using the antibodies and antigen-binding fragments. The antibodies and antigen-binding fragments can be used to inhibit the classical pathway of complement activation in a subject, e.g., a human. The antibodies and antigen-binding fragments can also be used to inhibit the lectin pathway of complement activation in a subject, e.g., a human.

The present invention relates to variant Fc-containing molecules, such as antibodies and Fc-fusion molecules, having glycosylation characteristics favorable to large-scale production of therapeutic molecules containing such variant Fc.
