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. Such TILs find use in therapeutic treatment regimens.
Claims15
A method for treating a subject with cancer, the method comprising administering to the subject an expanded population of tumor infiltrating lymphocytes (TILs) that exhibit IFN-γ secretion of at least five-fold in vitro as compared to a non-expanded population of TILs.
