Provided are antibodies that target the cellular efflux pump ABCC1. Also provided are pharmaceutical compositions, nucleic acids, recombinant expression vectors, cells, and kits that include or encode such antibodies. Methods of using the antibodies for detecting presence or absence of ABCC1 expression in cells, e.g., tumor cells, Level of ABCC1 expression, and/or inhibiting ABCC1 function are also disclosed. Also provided are methods for treating a subject for a cancer that include administering to the subject an anti-ABCC1 antibody disclosed herein. The subject antibody may be a bispecific antibody. The bispecific antibody may bind to ABCC1 and a tumor associated antigen (TAA).

The present invention in general relates to a combination of mRNA molecules encoding functional immunostimulatory proteins and a CTLA4 pathway inhibitor. In particular, it relates to a combination of one or more mRNA molecules encoding at least one functional immunostimulatory protein selected from the list comprising: CD40L, CD70 and caTLR4; and a CTLA4 pathway inhibitor, optionally also in the form of an mRNA molecule. The present invention further relates to vaccines comprising such combination, as well as uses of the combinations and vaccine of the present invention in human or veterinary medicine, in particular in the prevention and/or treatment of cell proliferative disorders.

The present disclosure provides an allogeneic whole cell cancer vaccine platform that includes compositions and methods for treating and preventing breast cancer. Provided herein are compositions containing a therapeutically effective amount of cells from one or more cancer cell lines, some or all of which are modified to (i) inhibit or reduce expression of one or more immunosuppressive factors by the cells, and/or (ii) express or increase expression of one or more immunostimulatory factors by the cells, and/or (iii) express or increase expression of one or more tumor-associated antigens (TAAs), including TAAs that have been mutated, and which comprise cancer cell lines that natively express a heterogeneity of tumor associated antigens and/or neoantigens, and/or (iv) express one or more tumor fitness advantage mutations, including but not limited to driver mutations. Also provided herein are methods of making and preparing the breast cancer vaccine compositions and methods of use thereof.

The present application is related to a method of treating a cancer by administering to a human subject multiple doses of a mRNA cancer vaccine formulated as a lipid nanoparticle wherein the cancer vaccine comprises one or more mRNAs each having one or more open reading frames encoding 3-50 peptide epitopes, and wherein each of the peptide epitopes are portions of personalized cancer antigens or portions of cancer hotspot antigens. The present application further relates to a method of treating cancer by combining anti-cancer immunotherapy with the administration of the aforementioned mRNA cancer vaccine.

The present invention relates to T cell receptors (TCRs) that bind the HLA-A*02 restricted peptide SLLQHLIGL (SEQ ID NO: 1) derived from the germline cancer antigen PRAME. Said TCRs may comprise non-natural mutations within the alpha and/or beta variable domains relative to a native PRAME TCR. The TCRs of the invention are particularly suitable for use as novel immunotherapeutic reagents for the treatment of malignant disease.

T cells, notably CD8 T cells, are known to be essential players in tumor eradication as the presence of tumor-infiltrating lymphocytes (TILs) in several cancers positively correlates with a good prognosis. To eliminate tumor cells, CD8 T cells recognize tumor antigens, which are MHC I-associated peptides present at the surface of tumor cells, with no or very low expression on normal cells. Described herein a proteogenomic approach using RNA-sequencing data from cancer and normal-matched mTEC.sup.hi samples in order to identify non-tolerogenic tumor-specific antigens derived from (i) coding and non-coding regions of the genome, (ii) non-synonymous single-base mutations or short insertion/deletions and more complex rearrangements as well as (iii) endogenous retroelements, which works regardless of the sample's mutational load or complexity.

Disclosed is the use of a combination of an anti-PD-1 antibody and a VEGFR inhibitor in the preparation of a drug for treating cancers.

The disclosure provides a chimeric antigen receptor (CAR) polypeptide having an antigen binding domain comprising an extracellular lectin which specifically binds to glycoproteins expressed on the surface of target cells. Also provided herein are engineered lymphocytes expressing the CAR polypeptide, a nucleic acid molecule encoding the CAR polypeptide, and methods of treating cancer.

Use of an IL-Iβ binding antibody or a functional fragment thereof, especially canakinumab or a functional fragment thereof, or gevokizumab or a functional fragment thereof, and biomarkers for the treatment of cancer with at least partial inflammatory basis, e.g., CML.

The disclosure teaches antibodies that are useful, inter alia, in methods for detecting and treating human cancer. In a particular aspect, the disclosure teaches novel antibodies that are useful for detecting and treating human breast cancer. In some embodiments, the disclosure teaches novel antibodies that bind to filamin A. In some embodiments, the antibodies are intrabodies.
