Provided herein are novel αPD-L1 antibodies and methods of using such antibodies for the treatment of cancers. In some embodiments, the antibodies are αPD-L1×αCD28 bispecific antibodies. Such antibodies enhance anti-tumor activity by providing a costimulatory signal for T-cell activation against tumor cells while advantageously also blocking inhibitory PD-L1:PD-1 pathway interactions.

The present application relates to CTLA4-Ig immunoadhesins that target CD80 and CD86, and their use, particularly for therapeutic purposes.

The present disclosure relates to immunoglobulins that bind FcγRIIb+ B cells and coengage CD19 on the cell's surface and an FcγRIIb on the cell's surface, methods for their generation, and methods for using the immunoglobulins for the treatment of an IgG4-related disease.

The present invention is directed to novel targeted heterodimeric fusion proteins comprising an IL-15/IL-15Rα Fc-fusion protein and a LAG-3 antibody fragment-Fc fusion protein.

The present invention is directed to heterodimeric anti-LAG-3 x anti-CTLA-4. Also provided are nucleic acid compositions that encode the antibodies, expression vector compositions that include the nucleic acids, and host cells that include the expression vector compositions.

Provided herein are novel anti-CD28× anti-PSMA antibodies and methods of using such antibodies for the treatment of PSMA-associated cancers. Subject anti-CD28× anti-PSMA antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and PSMA 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 in combination with other anti-cancer therapies (e.g., anti-CD3× anti-PSMA antibodies) for the treatment of prostate cancers.

The present invention provides methods of treating and improving the symptoms of multiple sclerosis using an antibody or antigen-binding fragment thereof that specifically binds human CD19 (e.g., obexclimab).

Provided herein are novel anti-CD20 x anti-CD28 antibodies and methods of using such antibodies for the treatment of B-cell malignancies. Subject anti-CD20 x anti-CD28 antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and CD20 on tumor cells. Thus, such antibodies enhance anti-tumor activity at tumor sites. The subject antibodies provided herein are particularly useful in combination with other anti-cancer therapies (e.g., anti-CD3 x anti-CD20 x anti-CD79b antibodies) for the treatment of B-cell malignancies.

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

Provided herein are novel anti-CD28×anti-ENPP3 antibodies and methods of using such antibodies for the treatment of ENPP3-associated cancers. Subject anti-CD28×anti-ENPP3 antibodies are capable of agonistically binding to CD28 costimulatory molecules on T cells and ENPP3 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 in combination with other anti-cancer therapies, including, for example, bispecific antibodies for the treatment of ENPP3-associated cancers.
