The present disclosure relates to compositions comprising isolated T cells, with activity against a fungal antigen, a viral antigen or a tumour antigen, wherein the composition comprises a defined number or defined ratio of T cells. Described herein are compositions comprising at least two populations of T cells, the compositions being suitable for treating various diseases and disorders.

The present invention relates to a nucleic acid sequence, comprising or coding for a coding region, encoding at least one peptide or protein comprising a tumour antigen or a fragment, variant or derivative thereof, at least one histone stem-loop and a poly(A) sequence or a polyadenylation signal. Furthermore the present invention provides the use of the nucleic acid for increasing the expression of said encoded peptide or protein. It also discloses its use for the preparation of a pharmaceutical composition, especially a vaccine, e.g. for use in the treatment of cancer or tumour diseases. The present invention further describes a method for increasing the expression of a peptide or protein comprising a tumour antigen or a fragment, variant or derivative thereof, using the nucleic acid comprising or coding for a histone stem-loop and a poly(A) sequence or a polyadenylation signal.

The present disclosure provides methods and compositions related to the modification of immune effector cells to increase therapeutic efficacy. In some embodiments, immune effector cells modified to reduce expression of one or more endogenous target genes, or to reduce one or more functions of an endogenous protein to enhance effector functions of the immune cells are provided. In some embodiments, immune effector cells further modified by introduction of transgenes conferring antigen specificity, such as exogenous T cell receptors (TCRs) or chimeric antigen receptors (CARs) are provided. Methods of treating a cell proliferative disorder, such as a cancer, using the modified immune effector cells described herein are also provided.

Hematopoeitic stem/progenitor cells (HSPC) and/or non-T effector cells are modified to express an extracellular component including a tag cassette. The tag cassette can be used to activate, promote proliferation of, detect, enrich, isolate, track, deplete and/or eliminate modified cells. The cells can also be modified to express a binding domain.

The present invention provides a pharmaceutical composition containing a cancer antigen peptide for treatment and prevention of angiogenic diseases.

The present invention relates to a pharmaceutical composition comprising a modified mRNA that is stabilised by sequence modifications and optimised for translation. The pharmaceutical composition according to the invention is particularly well suited for use as an inoculating agent, as well as a therapeutic agent for tissue regeneration. In addition, a process is described for determining sequence modifications that promote stabilisation and translational efficiency of modified mRNA of the invention.

The present invention provides an immune enhancer comprising at least an interferon and a granulocyte-macrophage colony-stimulating factor, and an immunotherapeutic pharmaceutical composition comprising at least an antigen and the above-mentioned immune enhancers. The present invention further discloses a preparation method of the immunotherapeutic pharmaceutical composition, the use of the immune enhancer and the immunotherapeutic pharmaceutical composition. The immune enhancer can be applied to disease and tumor treatments caused by viruses, bacteria, and other microorganisms.

This invention provides methods of treating, reducing the incidence of, and inducing immune responses to a WT1-expressing cancer, by administering a combination of WT1 peptides including each of: YMFPNAPYL, RSDELVRHHNMHQRNMTKL, PGCNKRYFKLSHLQMHSRKHTG, SGQAYMFPNAPYLPSCLES, NLMNLGATL, WNLMNLGATLKGVAA, and WNYMNLGATLKGVAA, or cytotoxic T cells induced by the combination of WT1 peptides. The combination of WT1 peptides may be administered to the subject via a WT1 delivery agent, i.e., in peptide form, or in the form of nucleic acids encoding the WT1 peptides, or in the form of immune cells comprising nucleic acids encoding the WT1 peptides, and/or comprising or presenting the WT1 peptides. The WT1 delivery agents or CTLs can be administered to the subject in a single composition (as a heptavalent immunotherapy composition), or multiple compositions, resulting in delivery of all seven WT1 peptides and induction of an immune response against the WT1-expressing cancer.
