The invention provides compositions and methods for treating diseases associated with expression of CD20 or CD22. The invention also relates to chimeric antigen receptor (CAR) specific to CD20 or CD22, vectors encoding the same, and recombinant T or natural killer (NK) cells comprising the CD20 CAR or CD22 CAR. The invention also includes methods of administering a genetically modified T cell or NK cell expressing a CAR that comprises a CD20 or CD22 binding domain.

Provided is an effective amount of a desialylation agent and an effective amount of an anti CD38 antibody for use in the treatment of multiple myeloma. This results in potentiated primary NK cell activity against the multiple myeloma cell. Also envisaged is a method of treating multiple myeloma in a subject in need thereof.

Aspects of the present disclosure relate to compositions comprising a population of genetically engineered T cells that expresses a chimeric antigen receptor (CAR) that binds CD70, and methods of using such for the treatment of T cell and B cell malignancies.

Disclosed herein are diagnostic and therapeutic methods for the treatment of hematologic cancers, including multiple myeloma (MM), as well as related compositions. In particular, the invention relates to diagnostic and therapeutic methods for treatments involving a PD-L1 axis binding antagonist (e.g., an anti-PD-L1 antibody, e.g., atezolizumab) and an anti-CD38 antibody (e.g., an anti-CD38 antagonist antibody, e.g., daratumumab) for use in treating hematologic cancer (e.g., a multiple myeloma (MM), e.g., a relapsed or refractory MM).

Provided herein are methods for preparing, producing, processing, culturing, isolating, or making cells suitable for immune or cell therapy, and for their use in cell therapy.

Aspects of the present disclosure relate to compositions comprising a population of genetically engineered T cells that expresses a chimeric antigen receptor (CAR) that binds CD70, and methods of using such for the treatment of T cell and B cell malignancies.

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.

The present invention relates to peptides, proteins, nucleic acids and cells for use in immunotherapeutic methods. In particular, the present invention relates to the immunotherapy of cancer. The present invention furthermore relates to tumor-associated T-cell peptide epitopes, alone or in combination with other tumor-associated peptides that can for example serve as active pharmaceutical ingredients of vaccine compositions that stimulate anti-tumor immune responses, or to stimulate T cells ex vivo and transfer into patients. Peptides bound to molecules of the major histocompatibility complex (MHC), or peptides as such, can also be targets of antibodies, soluble T-cell receptors, and other binding molecules.

The invention is directed to methods for determining antigen-specific T cells generally and to T cell receptors which bind an epitope of the Wilms' tumor antigen-1 (WT1) protein specifically. The disclosure also provides polynucleotides encoding the TCRs, engineered cells exogenously expressing the TCRs, and methods of making and using the TCRs and/or cells expressing the TCRs.

The presently disclosed subject matter provides methods for treating neoplasia using cells comprising an antigen-recognizing receptor (e.g., a chimeric antigen receptor (CAR)) that specifically targets CD127.
