Abstract: The invention provides antibody heavy chain constant regions with a hinge region modified to reduce binding to Fc? receptors. The modification occurs within positions 233-236 by replacement of natural residues by glycine(s) and/or deletion(s). Such modifications can reduce binding of an antibody bearing such a constant region to Fc? receptors to background levels. The constant regions can be incorporated into any format of antibody or Fc fusion protein. Such antibodies or fusion proteins can be used in methods of treatment, particularly those in which the mechanisms of action of the antibody or Fc fusion protein is not primarily or at all dependent on effector functions, as is the case when an antibody inhibits a receptor-ligand interaction or agonizes a receptor.

Abstract: The present invention provides compositions and methods for immunotherapy, which include shelf-stable pharmaceutical compositions for inducing antigen-specific T cells. Such compositions are employed as components of an artificial antigen presenting cell (aAPC), to provide a patient with complexes for presentation of an antigen (e.g., a tumor antigen) and/or a T cell co-stimulatory molecule.
Abstract: The present invention provides methods for treating, reducing the severity, or inhibiting the growth of cancer (e.g., skin cancer). The methods of the present invention comprise administering to a subject in need thereof a therapeutically effective amount of a programmed death 1 (PD-1) antagonist (e.g., an anti-PD-1 antibody). In certain embodiments, the skin cancer is cutaneous squamous cell carcinoma or basal cell carcinoma.
Abstract: Disclosed herein are methods for identifying a subject as having NSCLC that is predicted or is likely to respond to treatment with an ALK inhibitor, for example crizotinib. The methods include identifying a sample including NSCLC tumor cells as ALK-positive or ALK-negative using immunohistochemistry (IHC) and scoring methods disclosed herein. A subject is identified as having NSCLC likely to respond to treatment with an ALK inhibitor if the sample is identified as ALK-positive and is identified as having NSCLC not likely to respond to treatment with an ALK inhibitor if the sample is identified as ALK-negative. According to certain embodiments of the methods, subjects predicted to respond to an ALK inhibitor may then be treated with an ALK inhibitor such as crizotinib.
