Abstract: Provided herein are methods to overcome drug resistance by re-sensitizing cancer cells to treatment with a prior therapy via treatment with a T cell therapy.

Abstract: Provided herein are uses of anti-B cell maturation antigen (BCMA) chimeric antigen receptors (CARs) for treating B-cell related conditions, such as BCMA-expressing cancers.

Abstract: Provided are methods for determining the risk of toxicity (e.g., neurotoxicity) and/or the likelihood of response to a cell therapy. In some aspects, the methods generally involve assessing parameters or biomarkers (e.g., blood analytes) that are associated with toxicity and/or response. In some aspects, the methods relate to adoptive cell therapy involving the administration of doses of cells for treating subjects with certain B cell malignancies, such as chronic lymphocytic leukemia (CLL), such as relapsed or refractory CLL, or small lymphocytic lymphoma (SLL). The cells for the adoptive cell therapy generally express recombinant receptors such as chimeric antigen receptors (CARs). In some aspects, the methods can be used to identify or select subjects for treatment, for example, with a cell therapy.
