Abstract: This invention relates to cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4) protein compositions and their use in the mitigation of autoimmune adverse events associated with cancer immunotherapy. Specifically, the disclosure provides a CTLA-4 protein comprising a mutant extracellular domain of CTLA-4, wherein the CTLA-4 protein exhibits reduced binding to an anti-CTLA-4 antibody as compared to a wild-type extracellular domain of CTLA-4, wherein the anti-CTLA-4 antibody has anti-cancer immunotherapeutic activity.
