Abstract: The present invention provides compositions comprising chimeric receptors, including chimeric costimulatory receptors (CCRs), and/or chemokine receptors, methods for preparing CCRs and/or chemokine receptors, and therapeutic populations of tumor infiltrating lymphocytes, marrow infiltrating lymphocytes, and peripheral blood lymphocytes expressing CCRs and/or chemokine receptors with increased therapeutic performance and other advantages for the treatment of cancers, including solid tumor cancers.

Abstract: Provided herein are TILs that are (i) CD39LO/CD69LO and/or CD39/CD69 double negative, (ii) CD39/CD69 double knock-out, or (iii) the combination of (i) and (ii). In some embodiments, the subject TILs are produced by genetically manipulating a population of TILs that have been selected for (i) CD39LO/CD69LO and/or CD39/CD69 double negative, (ii) CD39/CD69 double knock-out, or (iii) the combination of (i) and (ii) expression (e.g, a (i) CD39LO/CD69LO and/or CD39/CD69 double negative, (ii) CD39/CD69 double knock-out, or (iii) the combination of (i) and (ii) enriched TIL population). Also provided herein are expansion methods for producing such genetically modified TILs and methods of treatment using such TILs.

Abstract: Provided herein are methods of producing TILs via (i) pre-REP stimulation with a combination of interferon gamma (IFN?) and an anti-PD-1 antibody, with or without a CD40 agonist, and with or without an anti-CTLA-4 antibody (ii) various concentrations of IL-15 and IL-21, with or without low-concentration IL-2, with or without an AKT inhibitor (AKTi) during REP expansion and/or pre-REP expansion, (iii) low-concentration IL-2 and an AKTi during REP expansion and/or pre-REP expansion, (iv) the combination of (i) and (ii), or (v) the combination of (i) and (iii).

Abstract: The invention provides methods for identifying an individuals with a disease or disorder who is less likely to respond to immunotherapy alone, the method comprising determining the presence of a stromal gene signature in a sample from the individual, said signature comprising one or more of FAP, FN1, MMP2, PDGFRB, or THY, wherein an increase in the level of expression of the one or more genes in the stroma gene signature relative to a median level identifies an individual for treatment with an immunotherapy and with a suppressive stromal antagonist. In some aspects, the invention provides methods for treating an individual displaying the stromal gene signature. In other aspects, the invention provides kits for determining the presence of a stroma gene signature in a sample from an individual.
