Abstract
PURPOSE OF THE STUDY The use of chimeric antigen receptor (CAR)-T cells has demonstrated excellent results in B-lymphoid malignancies. The Advanced Therapy Medicinal Products (ATMP) status and good manufacturing practice (GMP) of CAR-T cells require particular conditions of production performed in a pharmaceutical establishment. Our team developed a new medical drug candidate for acute myeloid leukemia (AML), a CAR targeting interleukin-1 receptor accessory protein (IL-1RAP) expressed by leukemia stem cells, which will need to be evaluated in a phase I-IIa clinical trial. During the preclinical development phase, we produced IL-1RAP CAR-T cells in a semi-automated closed system (CliniMACSࣨ Prodigy) using research grade lentiviral particles. PATIENTS AND THE METHODS The purpose of this work was to validate our production process and to characterize our preclinical GMP-like medicinal product. IL-1RAP CAR-T cells were produced from healthy donors in 9 days, either in an semi-automated closed system (with GMP-like compliant conditions) or according to another research protocols, which was used as a reference. RESULTS Based on phenotypic, functional and metabolic analyses, we were able to show that the final product is ready for clinical use. Finally, in a xenograft AML murine model, we demonstrated that the IL-1RAP CAR-T cells generated in a GMP-like environment could eliminate tumor cells and increase overall survival. CONCLUSION We demonstrated that our IL-1RAP CAR-T cell preclinical GMP-like production process meets standard regulatory requirements in terms of CAR-T cell number, subpopulation phenotype and cytotoxic functionality. Our CAR-T cell production process was validated and can be used to produce medicinal IL-1RAP CAR-T cells for the first phase I clinical trial.

Abstract
Numerous preclinical and clinical studies have demonstrated the significant contribution of inflammation to the development and progression of various types of cancer. Inflammation in the tumor microenvironment mediates complex interactions between innate immunity, adaptive immunity, microbiomes and stroma, and ultimately alters the overall fitness of tumor cells at multiple stages of carcinogenesis. Malignancies are known to arise in areas of chronic inflammation and inflammation in the tumor microenvironment (often called tumor-promoting inflammation) is believed to allow cancer cells to evade immunosurveillance while promoting genetic instability, survival and progression. Among the strongest data suggesting a causal role for inflammation in cancer come from the recent CANTOS trial which demonstrated that interleukin-1β (IL-1β) inhibition with canakinumab leads to a significant, dose-dependent decrease in incident lung cancer. This observation has launched a series of additional clinical studies to understand the role of IL-1β and the inflammasome in cancer, and the clinical utility of IL-1β inhibition in different stages of lung cancer. In this article we will review recent data implicating IL-1β signaling and its upstream regulator NLRP3 in both solid tumor and hematologic malignancies. We will discuss the key preclinical observations and the current clinical landscape, and describe the pharmacologic tools which will be used to evaluate the effects of blocking tumor-promoting inflammation clinically.
