Abstract: Provided herein are compositions and methods for the treatment of cancers using modified TILs, wherein the modified TILs include one or more immunomodulatory agents (e.g., cytokines) associated with their cell surface. The immunomodulatory agents associated with the TILs provide a localized immunostimulatory effect that can advantageously enhance TIL survival, proliferation and/or anti-tumor activity in a patient recipient. As such, the compositions and methods disclosed herein provide effective cancer therapies.

Abstract: The present invention provides improved and/or shortened processes and methods for reprogramming TILs in order to prepare therapeutic populations of TILs with increased therapeutic efficacy. Such reprogrammed TILs find use in therapeutic treatment regimens.

Abstract: The present invention provides methods for expanding TILs and producing therapeutic populations of TILs. According to exemplary embodiments, at least a portion of the therapeutic population of TILs are gene-edited to enhance their therapeutic effect. According to further embodiments, methods for gene-editing TILs include intratumoral delivery of expression vectors for immune checkpoint inhibitors using an electroporation system prior to harvesting the tumor for TIL production. According to yet further embodiments, an adjuvant therapy for cancer includes delivery of expression vectors for immune checkpoint inhibitors before, after or before and after infusion of TILs for treating cancer.

Abstract: The present invention provides improved and/or shortened methods for expanding TILs and producing therapeutic populations of TILs, including novel methods for expanding TIL populations in a closed system that lead to improved efficacy, improved phenotype, and increased metabolic health of the TILs in a shorter time period, while allowing for reduced microbial contamination as well as decreased costs. The methods may comprise gene-editing at least a portion of the TILs to enhance their therapeutic efficacy. Such TILs find use in therapeutic treatment regimens.

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: The present invention relates to methods for expanding TILs from tumor tissue using a long first expansion process and a shorter second expansion process. A method for expanding TIL includes obtaining a first population of TILs from a tumor resected from a subject, performing a first expansion for a period of about 21 day to about 35 days by culturing the first population of TILs in a cell culture medium comprising 4-1BB agonist, IL-2, and OKT-3 to produce a second population of TILs, and performing a second expansion for a period of about 7 days to about 10 days by supplementing the cell culture medium of the second population of TILs with antigen presenting cells (APCs) and additional 4-1BB agonist, IL-2, and OKT-3, and culturing to produce a third population of TILs, wherein the third population of TILs is a therapeutic population of TILs.
