Non-human animals, and methods and compositions for making and using the same, are provided, wherein the non-human animals comprise a humanization of a Lymphocyte activation gene 3 (Lag3). The non-human animals may be described, in some embodiments, as having a genetic modification to an endogenous Lag3 locus so that the non-human animals express a Lag3 polypeptide that includes a human portion and an endogenous portion (e.g., a non-human portion).

Non-human animals having a humanized lymphocyte-activation gene 3

Non-human animals, methods and compositions for making and using the same, are provided, wherein said non-human animals comprise a humanization of a Cluster of Differentiation 274 (CD274) gene. Such non-human animals may be described, in some embodiments, as having a genetic modification to an endogenous CD274 gene so that said non-human animals express a Programmed cell death ligand 1 (PD-L) polypeptide that includes a human portion and an endogenous portion (e.g., a non-human portion).

Genetically modified mouse that expresses humanized PD1 and PD-L1 proteins

The present invention provides antibodies that bind to cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), and methods of use. In various embodiments of the invention, the antibodies are fully human antibodies that specifically bind to CTLA-4. In some embodiments, the antibodies of the invention are useful for inhibiting or neutralizing CTLA-4 activity, thus providing a means of activating T-cells and/or for treating a disease or disorder such as cancer or viral infection.

Anti-CTLA-4 antibodies and uses thereof

The present invention provides antibodies that bind to the T cell co-inhibitor lymphocyte activation gene 3 (LAG3) protein, and methods of use. In various embodiments of the invention, the antibodies are fully human antibodies that specifically bind to LAG3. In some embodiments, the antibodies of the invention are useful for inhibiting or neutralizing LAG3 activity, thus providing a means of treating a disease or disorder such as cancer or viral infection.

Anti-LAG3 antibodies and uses thereof

Non-human animals, and methods and compositions for making and using the same, are provided, wherein the non-human animals comprise a humanization of a Programmed cell death 1 (Pdcd1) gene. The non-human animals, in some embodiments, comprise a genetic modification to an endogenous Pdcd1 gene so that the non-human animals express a PD-1 polypeptide that includes a human portion and an endogenous portion (e.g., a non-human portion).

Non-human animals having a humanized programmed cell death 1 gene

The present invention provides antibodies that bind to the T-cell co-inhibitor ligand programmed death-ligand1 (PD-L1) protein, and methods of use. In various embodiments of the invention, the antibodies are fully human antibodies that bind to PD-L1. In certain embodiments, the present invention provides multi-specific antigen-binding molecules comprising a first binding specificity that binds to PD-L1 and a second binding specificity that binds to a tumor cell antigen, an infected cell-specific antigen, or a T-cell co-inhibitor. In some embodiments, the antibodies of the invention are useful for inhibiting or neutralizing PD-L1 activity, thus providing a means of treating a disease or disorder such as cancer or viral infection.

Human antibodies to PD-L1

Non-human animals, methods and compositions for making and using the same, are provided, wherein said non-human animals comprise a humanization of a Cluster of Differentiation 274 (CD274) gene. Such non-human animals may be described, in some embodiments, as having a genetic modification to an endogenous CD274 gene so that said non-human animals express a Programmed cell death ligand 1 (PD-L1) polypeptide that includes a human portion and an endogenous portion (e.g., a non-human portion).

Genetically modified mouse whose genome comprises a humanized CD274 gene

The present invention provides antibodies that bind to the T-cell co-inhibitor programmed death-1 (PD-1) protein, and methods of use. In various embodiments of the invention, the antibodies are fully human antibodies that bind to PD-1. In certain embodiments, the present invention provides multi-specific antigen-binding molecules comprising a first binding specificity that binds to PD-1 and a second binding specificity that binds to an autoimmune tissue antigen, another T-cell co-inhibitor, an Fc receptor, or a T-cell receptor. In some embodiments, the antibodies of the invention are useful for inhibiting or neutralizing PD-1 activity, thus providing a means of treating a disease or disorder such as cancer or a chronic viral infection. In other embodiments, the antibodies are useful for enhancing or stimulating PD-1 activity, thus providing a means of treating, for example, an autoimmune disease or disorder.

Human antibodies to PD-1

The present invention provides pharmaceutical compositions comprising a VEGF antagonist and an anti-CTLA-4 antibody, and methods of use thereof. The compositions and methods of the present invention are useful for the treatment of cancers and other diseases and disorders in which anti-angiogenic therapies and/or targeted immune responses may be beneficial.

Methods and compositions comprising a combination of a VEGF antagonist and an anti-CTLA-4 antibody

Non-human animals, and methods and compositions for making and using the same, are provided, wherein the non-human animals comprise a humanization of a Programmed cell death 1 (Pdcd1) gene. The non-human animals may be described, in some embodiments, as having a genetic modification to an endogenous Pdcd1 gene so that the non-human animals express a PD-1 polypeptide that includes a human portion and an endogenous portion (e.g., a non-human portion).
