Abstract: The present disclosure relates to compositions and methods for enhancing T cell response and/or CAR cell expansion and/or maintenance in vivo and/or in vitro. For example, a method of enhancing T cell-based therapy comprises administering genetically modified T cells comprising a first chimeric antigen receptor (CAR) and a second CAR, wherein a binding domain of the first CAR binds a first antigen, and a binding domain of the second CAR binds a second antigen. The first antigen is different from the second antigen. In embodiments, the first CAR binds a surface molecule or antigen of a white blood cell.
Abstract: The present invention is directed to bi-specific monovalent diabodies that comprise two polypeptide chains and which possess at least one binding site specific for an epitope of CD3 and one binding site specific for an epitope of gpA33 (i.e., a “gpA33×CD3 bi-specific monovalent diabody”). The present invention also is directed to bi-specific monovalent diabodies that comprise an immunoglobulin Fc Domain (“bi-specific monovalent Fc diabodies”) and are composed of three polypeptide chains and which possess at least one binding site specific for an epitope of gpA33 and one binding site specific for an epitope of CD3 (i.e., a “gpA33×CD3 bi-specific monovalent Fc diabody”). The bi-specific monovalent diabodies and bi-specific monovalent Fc diabodies of the present invention are capable of simultaneous binding to gpA33 and CD3. The invention is directed to pharmaceutical compositions that contain such bi-specific monovalent diabodies or such bi-specific monovalent Fc diabodies.

Abstract: 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.

Abstract: The present invention relates to methods of cancer therapy using subcutaneous administration of antibody-drug conjugates (ADCs). Preferably, the ADC comprises an antibody that binds to Trop-2, CEACAM5, CEACAM6, CD20, CD22, CD30, CD46, CD74, Her-2, folate receptor, or HLA-DR. More preferably, the drug is SN-38. Subcutaneous administration is at least as effective as intravenous administration of the same ADC. Surprisingly, subcutaneous administration can be used without inducing unmanageable adverse local toxicity at the injection site. Subcutaneous administration is advantageous in requiring less frequent administration, substantially reducing the amount of time required for intravenous administration, and reducing the levels of systemic toxicities observed with intravenous administration.
Abstract: Subject matter of the present invention is an anti-ADM antibody or anti-ADM antibody fragment or anti-ADM non-Ig scaffold binding to the C-terminal portion of ADM, the aa 43-52 of ADM (SEQ ID NO: 1): APRSKISPQGY-NH2 for use in a therapy of cancer. Subject matter of the present invention is anti-ADM antibody or anti-ADM antibody fragment or anti-ADM non-Ig scaffold for use in the treatment of cancer according to claim 1 wherein said anti-ADM antibody or anti-ADM antibody fragment or anti-ADM non-Ig scaffold requires the presence of a C-terminally amidated tyrosine residue within the C-terminal portion of ADM, the aa 43-52 of ADM (SEQ ID NO: 1): APRSKISPQGY-NH2, for binding.
