The present invention is directed to regimens for administering one or more Antibody-Based Molecules that bind PD-1 or PD-L1, and LAG-3 (e.g, a PD-1×LAG-3 bispecific molecule) alone, or in combination with an Antibody-Based Molecule that binds a Tumor Antigen (TA) for the treatment of cancer. The invention particularly concerns the use of such regimens in conjunction with PD-1×LAG-3 bispecific molecules. The invention is directed to the use of such molecules, and to the use of pharmaceutical compositions and pharmaceutical kits that contain such molecules and that facilitate the use of such dosing regimens in the treatment of cancer.

Provided are multi-specific antigen binding molecules, including bispecific antibodies, that bind to CD3 and an HIV antigen, including HIV envelope protein gp120. Also provided are methods of using such antigen binding molecules to treat or prevent HIV infection.

The present invention provides isolated monoclonal antibodies, particularly human antibodies, that bind to human Cluster of Differentiation 73 (CD73) with high affinity, and inhibit the activity of CD73, and optionally mediate antibody dependent CD73 internalization. Nucleic acid molecules encoding the antibodies of the invention, expression vectors, host cells and methods for expressing the antibodies of the invention are also provided. Immunoconjugates, bispecific molecules and pharmaceutical compositions comprising the antibodies of the invention are also provided. The invention also provides methods for inhibiting the growth of a tumor cell expressing CD73 using the antibodies of the invention, including methods for treating various cancers.

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

The present invention relates to a polypeptide including an Fc variant produced by substituting a portion of the amino acid sequence of the Fc domain of a human antibody with a different amino acid sequence. The present invention also relates to an antibody including the polypeptide. The Fc variant can find application in a wide range of antibodies and Fc-fusion constructs. In one aspect, the antibody or Fc fusion construct of the present invention is a therapeutic, diagnostic or laboratory reagent, preferably a therapeutic reagent. The Fc variant is suitable for use in the treatment of cancer because its in vivo half-life can be maximized by optimization of the portion of the amino acid sequence. The antibody or Fc fusion construct of the present invention is used to kill target cells that bear a target antigen, for example cancer cells. Alternatively, the antibody or Fc fusion construct of the present invention is used to block, antagonize or agonize a target antigen. For example, the antibody or Fc fusion construct of the present invention may be used to antagonize a cytokine or a cytokine receptor.

The invention provides humanized antibodies binding to CLDN18.2 with a high affinity. Further, the antibodies do not exhibit cross-reactivity to CLDN18.1. The invention also provides nucleic acids, vectors, host cells and medical uses.

The present disclosure includes a fusion protein, called a “Seldeg”, including a targeting component that specifically binds to a cell surface receptor or other cell surface molecule at near-neutral pH, and an antigen component fused directly or indirectly to the targeting component. The antigen component is configured to specifically bind a target antigen-specific antibody. The present disclosure also includes a method of depleting a target antigen-specific antibody from a patient by administering to the patient a Seldeg having an antigen component configured to specifically bind the target antigen-specific antibody.

Fc regions comprising modification to increase the affinity of association between the Fc region and TRIM21 are disclosed. Also disclosed are constituent polypeptides of such Fc regions, antigen-binding molecules and immunogens comprising such Fc regions, and nucleic acids encoding and methods using such Fc regions, antigen-binding molecules and immunogens.

This invention concerns anti-inflammatory agents, compositions, and methods for treating inflammatory disorders.
