The invention relates to array-based methods for identification of neoepitope reactive T cells and to compositions produced using such methods. Aspects of the invention relate to rapid and reliable methods to identify neoepitope reactive T cells.

Disclosed herein relates to immunotherapeutic compositions comprising immunotherapeutic peptides comprising neoepitopes, polynucleotides encoding the immunotherapeutic peptides, antigen presenting cells comprising the immunotherapeutic peptides or polynucleotides, or T cell receptors specific for the neoepitopes. Also disclosed herein is use of the immunotherapeutic compositions.

The present invention relates to chimeric receptors capable of facilitating cross-presentation (XP) of antigens, and methods of doing the same.

The present disclosure provides novel artificial antigen presenting cells (aAPCs). The aAPCs disclosed herein comprise a liposome comprising a phospholipid and a stimulatory ligand displayed on the outer surface of the liposome. The aAPCs of the present disclosure can be used as an off the shelf tool to activate and expand a T cell of interest. Also, the present disclosure provides methods of activating a T cell and manufacturing a T cell therapy product using the aAPCs disclosed herein.

Disclosed are compositions neoantigens and T cell receptors (TCRs) specific for one or more neoantigens as well as methods of their use for treating cancer.

The present disclosure relates to a method for selecting a tumor neoantigenic peptide wherein said method comprises: a step of identifying, among mRNA sequences from cancer cells of a subject, a fusion transcript sequence comprising a transposable element (TE) sequence and an exonic sequence, and including an open reading frame (ORF), and a step of selecting a tumor neoantigenic peptide of at least 8 amino acids, encoded by a part of said ORF of the fusion transcript sequence, wherein said ORF overlaps the junction between the TE and the exonic sequence, is pure TE and/or is non-canonical, and wherein said tumor neoantigenic peptide binds to at least one Major Histocompatibility Complex (MHC) molecule of said subject. The present disclosure also relates to tumor neoantigenic peptide obtained according to the present method, vaccine or immunogenic composition, antibodies and immune cells derived thereof and their use in therapy of cancer.

Compositions comprising and methods for the treatment of cancer using a NeoTCR based cell therapy with a modified TGF?RII expression.

The present invention describes a method for treating cancer comprising adoptive transfer of tumor antigen specific CD8+ T cells and an oncolytic virus vaccine targeting the same antigen.

Methods described herein relate to constructing therapeutic fusion-specific vaccine libraries, selecting a therapeutic fusion-specific vaccine for a cancer patient, and/or constructing a de novo therapeutic fusion-specific vaccine for patients having a gene fusion that is absent from a fusion-specific vaccine library.
