  • Patent number: 11896665
    Abstract: An isolated protein comprises respective amino acid sequences of each of a plurality of CTL epitopes from two or more different herpesvirus antigens and further comprises an intervening amino acid or amino acid sequence between at least two of said CTL epitopes comprising proteasome liberation amino acids or amino acid sequences and, optionally, Transporter Associated with Antigen Processing recognition motifs. The isolated protein is capable of rapidly expanding human cytotoxic T lymphocytes (CTL) in vitro and eliciting a CTL immune response in vivo upon administration to an animal as an exogenous protein. Typically, the isolated protein comprises no more than twenty (20) CTL epitopes derived from cytomegalovirus and/or Epstein-Barr virus antigens.

  • Publication number: 20230348558
    Abstract: Disclosed are compositions and methods for targeted treatment of cancer, such as HPV-associated cancer. In particular, modified T cell receptor (TCR) T cells are disclosed that can be used with adoptive cell transfer to target and kill cancer cells with reduced antigen escape. Therefore, also disclosed are methods of providing an anti-tumor immunity in a subject with HPV-associated cancer that involves adoptive transfer of the disclosed TCR-T cells.

  • Publication number: 20230210984
    Abstract: Disclosed herein is the use of a first population of allogeneic T-cells recognizing a first EBV epitope, and a second allogeneic population recognizing a second EBV epitope in the treatment of EBV-associated disorders. Also disclosed is the use of a population of allogeneic T-cells recognizing an EBV antigen in combination with a further therapeutic agent such as an immunotherapeutic agent, a MAPK, BET or MEK. pathway inhibitor for treating EBV-associated disease.

  • Publication number: 20230181642
    Abstract: Disclosed are T-cells that are positive for CD49f and which have an enhanced function compared to CD49f? cells. Methods of isolation of CD49f+ T-cells, as well as compositions and kits thereof are also disclosed. Additionally, enriched CD49f+T-cell populations have an increased proliferative potential, long-term survival and significantly improved efficacy in an adoptive therapeutic setting. The CD49f+ T-cells and CD49f+ T-cell enriched T-cell populations are useful in a range of applications, including for use in treating or inhibiting the development of diseases with immune dysfunction and methods of assessing risk of disease and potential responsiveness in immunotherapy. CD 19 CAR-T cells derived from CD49f+ T-cells and their use in a method of treatment of cancer is also disclosed.
