Abstract: The present invention is directed to methods for treating a solid cancerous cancer through administering a bispecific anti-PD1 x anti-CTLA4 antibody.

Abstract: The present invention is directed to novel IL-15/IL-15R? heterodimeric Fc fusion proteins and uses thereof. The IL-15/IL-15R? heterodimeric Fc fusion proteins can be administered to a patient to treat cancer. In some cases, the IL-15/IL-15R? heterodimeric Fc fusion protein is administered in combination with a checkpoint blockage antibody such as a PD-1 antibody.

Abstract: The present invention provides novel IL-12 Fc fusion proteins, methods of making and using the same. The IL-12 Fc fusion proteins are useful for treatment of cancer and can be used in combination with checkpoint blockade.

Abstract: The present application relates to optimized IgG immunoglobulin variants, engineering methods for their generation, and their application, particularly for therapeutic purposes.

Abstract: The present invention relates to novel antigen binding domains and heterodimeric antibodies that bind Fibroblast Activation Protein (FAP).

Abstract: The present invention is directed to bispecific, heterodimeric checkpoint antibodies.

Abstract: The present invention is directed to a novel targeted heterodimeric Fc fusion proteins comprising an IL-15/IL-15R? Fc fusion protein and an antigen binding domain Fc fusion proteins. In some instances, the antigen binding domain binds to CD8, NKG2A, or NKG2D.

Abstract: The present invention is directed to heterodimeric antibodies that bind CD3 and CD38.

Abstract: The disclosure relates to methods of detecting one or more biomarkers. and/or treating autoimmune diseases such as systemic lupus erythematous (SLE) with an anti-CD19 antibody based on the presence of such biomarkers. The biomarkers can be separate or in combination, and their detection can be used in multiple different methods.

Abstract: The present invention is directed to antibodies, including novel antigen binding domains and heterodimeric antibodies, that bind somatostatin receptor 2 (SSTR2).

Abstract: The present invention provides untargeted and targeted IL-10-Fc fusion proteins, compositions and methods of use thereof. The targeted IL-10-Fc fusion proteins includes those that bind PD-1, TIGIT, CD8 and NKG2D.

Abstract: Provided herein, in certain aspects, are methods for the treatment of a CD20-expressing cancer in a human subject, comprising administration of a bispecific anti-CD20×anti-CD3 antibody (e.g., XmAb® 13676) to the human subject in a flat escalation dosing regimen including at least four phases (e.g., five phases or more than five phases).

Abstract: The present invention provides IL-2-Fc fusion proteins comprising IL-2 variants.

Abstract: The present invention is directed to novel heterodimeric antibodies.

Abstract: The present invention relates to fusion proteins comprising variant IL-15 proteins, fusion proteins comprising variant anti-PD-1 antigen binding domains, and fusion proteins comprising variant IL-15 proteins and variant anti-PD-1 antigen binding domains. The present invention also relates to nucleic acid molecules, expression vectors, host cells and methods for making such fusion proteins and the use of such fusion proteins in the treatment of cancer.

Abstract: The present application relates to a variant Fc region comprising at least one modification relative to a wild-type human Fc region, where the modification selected from the group consisting of 434S, 252Y/428L, 252Y/434S, and 428L/434S, and the numbering is according to the EU index.

Abstract: Provided herein are novel antigen binding domains and antibodies (e.g., heterodimeric antibodies) that bind Prostate Specific Membrane Antigen (PSMA). In exemplary embodiments, the anti-PSMA antibodies also bind CD3. Such antibodies that bind PSMA and CD3 are useful, for example in the treatment of PSMA-related cancer.

Abstract: Provided herein are novel anti-CD28×anti-B7H3 (also referred to as “?CD28×?B7H3”) heterodimeric bispecific antibodies and methods of using such antibodies for the treatment of cancers. Subject ?CD28×?B7H3 antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and targeting to B7H3 on tumor cells. Thus, such antibodies selectively enhance anti-tumor activity at tumor sites while minimizing peripheral toxicity. The subject antibodies provided herein are particularly useful for enhancing anti-tumor activity when used in combination with other anti-cancer therapies.

Abstract: The present invention is directed to novel heterodimeric antibodies.

Abstract: Provided herein are novel GPC3 binding domains, and antibodies that include such GPC3 binding domains (e.g., anti-GPC3×anti-CD3). Also provided herein are methods of using such antibodies for the treatment of GPC3-associated cancers.
