  • Publication number: 20210101956
    Abstract: Disclosed are T-cell receptors (TCRs) binding to tumor-associated antigens (TAAs) for targeting cancer cells, T-cells expressing same, methods for producing same, and methods for treating cancers using same. Disclosed are TCRs and their variants that bind to HLA class I or II molecules with a peptide, such as MAG-003 have the amino acid sequence of KVLEHVVRV (SEQ ID NO:1). The description further relates to peptides, proteins, nucleic acids, cells for use in immunotherapeutic methods, the immunotherapy of cancer, and 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.

  • Publication number: 20210032361
    Abstract: The present invention concerns antigen binding proteins specifically binding melanoma associated antigen A (MAGE-A) protein-derived antigens. The invention in particular provides antigen binding proteins which specifically bind to the MAGE-A antigenic peptide comprising or consisting of SEQ ID NO: 1 in a complex with a major histocombatibility (MHC) protein. The antigen binding proteins of the invention contain, in particular, the complementary determining regions (CDRs) of novel engineered T cell receptors (TCRs) that specifically bind to said MAGE-A peptide/MHC complex. The antigen binding proteins of the invention are of use for the diagnosis, treatment and prevention of MAGE-A expressing cancerous diseases. Further provided are nucleic acids encoding the antigen binding proteins of the invention, vectors comprising these nucleic acids, recombinant cells expressing the antigen binding proteins and pharmaceutical compositions comprising the antigen binding proteins of the invention.

  • Publication number: 20210032370
    Abstract: The present invention concerns bispecific antigen binding proteins directed against MHC presented target antigens (TA). The invention in particular provides bispecific antigen binding proteins comprising at least two antigen binding sites (A and B), wherein the antigen binding site A binds to CD3 and the antigen binding site B binds to a target antigenic (TA) peptide/MHC complex. The bispecific antigen binding proteins of the invention comprise, in particular, the CDRs of the VL and VH domains of novel engineered anti-CD3 antibodies having a reduced affinity. The bispecific antigen binding proteins of the invention are of use for the diagnosis, treatment and prevention of TA associated diseases, such as tumor-associated antigen (TAA) expressing cancerous diseases.

  • Publication number: 20200216518
    Abstract: The present invention is based on the discovery of polyclonal IgG's ability to promote Schwann cell maturation, differentiation, and myelin production. Methods for treating non-idiopathic, demyelinating peripheral neuropathies in mammals, where the neuropathy is not immune-mediated or infection-mediated, through the administration of polyclonal IgG are provided. Types of demyelinating peripheral neuropathies treatable with the present invention include peripheral nerve trauma and toxin-induced peripheral neuropathies. Alternatively, a composition of polyclonal IgGs can be applied directly to a peripheral nerve cell to induce maturation, differentiation into a myelinating state, and myelin expression or promote cell survival.
