T cells expressing Chimeric antigen receptors or CAR-T cells are used as a novel treatment against hematological and solid cancers. In this report, we designed CAR with glucocorticoid-induced TNFR-related protein (GITR) co-stimulatory domain to study its ability to co-activate CAR-T cells. EGFR-GITR-CD3 CAR-T cells were cytotoxic against EGFR-positive: pancreatic and ovarian cancer cells but not against EGFR-negative cancer cells. The cytotoxic activity of EGFR-GITR-CD3 CAR-T cells was comparable or better than EGFR-28-CD3 or EGFR-41BB-CD3 CAR-T cells...

BACKGROUND: Immunotherapy with chimeric antigen receptor (CAR)-modified T-cells targeting CD19 for pediatric acute lymphoblastic leukemia (ALL) has demonstrated significant efficacy. The principle toxicity is cytokine release syndrome with resultant hypotension. However, the spectrum of cardiovascular effects associated with CAR T-cell therapy has not been systematically evaluated. METHODS: We reviewed all patients who received CD19-directed CAR T-cells at the Children's Hospital of Philadelphia between April 2012 and September 2016...

B-cell non-Hodgkin's lymphomas are the most common hematological malignancies, which despite improvements in chemo-immunotherapy, carry a uniformly poor prognosis in the relapsed/refractory setting. CD19 is an antigen expressed on the surface of most malignancies arising from the B cells, and adoptive transfer of anti-CD19 chimeric antigen receptor (CAR)-expressing T cells has been shown to be effective in treating these B-cell malignancies. Axicabtagene ciloleucel (axi-cel, KTE-C19) is an autologous anti-CD19 CAR T-cell therapy which has shown high overall response rates and a manageable safety profile in patients with relapsed or refractory B-cell malignancies who lack effective and curative treatment options...

Tumor treatment is still complicated in the field of medicine. Tumor immunotherapy has been the most interesting research field in cancer therapy. Application of chimeric antigen receptor T (CAR-T) cell therapy has recently achieved excellent clinical outcome in patients, especially those with CD19-positive hematologic malignancies. This phenomenon has induced intense interest to develop CAR-T cell therapy for cancer, especially for solid tumors. However, the performance of CAR-T cell treatment in solid tumor is not as satisfactory as that in hematologic disease...

CD19 chimeric antigen receptor (CAR) T cell therapy has shown impressive results in treating acute lymphoblastic leukemia (B-ALL), chronic lymphoblastic leukemia (B-CLL), and B-cell non-Hodgkin lymphoma (B-NHL) over the past few years. Meanwhile, the cytokine release syndrome (CRS), which could be moderate or even life-threatening, has emerged as the most significant adverse effect in the clinical course of this novel targeting immunotherapy. In this systematic review, we analyzed the incidence of severe CRS in 19 clinical trials selected from studies published between 2010 and 2017...

Chimeric antigen receptor (CAR) T cell therapy is anticipated to be increasingly implemented in the context of cancer treatment after two current FDA approval of anti-CD19 CAR-T cells (Kymriah™ & Yescarta™). The success of CD19 is mainly attributable to the proper selection of the antigen, CD19, as the target of the disease, highlighting the importance of target selection for other CAR therapies. Therefore, here we performed a global analysis of targets that are the prime focus for various CAR T cell therapies in human clinical trials...

The use of chemotherapeutic agents prior to treatment with infusion of cluster of differentiation (CD)19-chimeric antigen receptor (CAR)‑T cells is important for the efficacy of clinical therapies against hematological malignancies. However, the effect of chemotherapeutic agents on CD19‑CAR‑T cells and the associated underlying mechanisms remain unknown. The first aim of the present study was to determine the effect of chemotherapeutic agents on CAR‑T cells using the in vitro Cell Counting kit 8 assay...

The clinical success of chimeric antigen receptor (CAR) T cell therapy for CD19+ B cell malignancies can be limited by acute toxicities and immunoglobulin replacement needs due to B cell aplasia from persistent CAR T cells. Life-threatening complications include cytokine release syndrome and neurologic adverse events, the exact etiologies of which are unclear. To elucidate the underlying toxicity mechanisms and test potentially safer CAR T cells, we developed a mouse model in which human CD19 (hCD19)-specific mouse CAR T cells were adoptively transferred into mice whose normal B cells express a hCD19 transgene at hemizygous levels...

The ability to harness a patient's immune system to target malignant cells is now transforming the treatment of many cancers, including hematologic malignancies. The adoptive transfer of T cells selected for tumor reactivity, or engineered with natural or synthetic receptors has emerged as an effective modality, even for patients with tumors that are refractory to conventional therapies. The most notable example of adoptive cell therapy is with T cells engineered to express synthetic chimeric antigen receptors (CARs) that reprogram their specificity to target CD19...

Tolerance to self-antigens prevents the elimination of cancer by the immune system1,2 . We used synthetic chimeric antigen receptors (CARs) to overcome immunological tolerance and mediate tumor rejection in patients with chronic lymphocytic leukemia (CLL). Remission was induced in a subset of subjects, but most did not respond. Comprehensive assessment of patient-derived CAR T cells to identify mechanisms of therapeutic success and failure has not been explored. We performed genomic, phenotypic and functional evaluations to identify determinants of response...

BACKGROUND: Standard-of-care therapies for treating pediatric medulloblastoma have long-term side effects, even in children who are cured. One emerging modality of cancer therapy that could be equally effective without such side effects would be chimeric antigen receptor (CAR) T cells. Knowing that human epidermal growth factor receptor 2 (HER2) is overexpressed in many medulloblastomas and has been used as a CAR T target before, we sought to evaluate the efficacy of more sophisticated anti-HER2 CAR T cells, as well as the feasibility and efficacy of different routes of delivering these cells, for the treatment of pediatric medulloblastoma...

Adoptive T cell therapy using chimeric antigen receptor (CAR)-modified T cells is a promising cancer immunotherapy. We previously developed a non-viral method of gene transfer into T cells using a piggyBac transposon system to improve the cost-effectiveness of CAR-T cell therapy. Here, we have further improved our technology by a novel culture strategy to increase the transfection efficiency and to reduce the time of T cell manufacturing. Using a CH2CH3-free CD19-specific CAR transposon vector and combining irradiated activated T cells (ATCs) as feeder cells and virus-specific T cell receptor (TCR) stimulation, we achieved 51...

BACKGROUND: Indoleamine 2,3-dioxygenase 1 (IDO1) catalyzes the first and rate-limiting step in converting tryptophan to kynurenine. Chimeric antigen receptor (CAR) T cells are T cells with recombinant receptors targeting tumor-associated antigens. The Food and Drug Administration has approved CAR T cells that target CD19 for treatment of advanced B cell leukemia and lymphoma. However, CAR T cell therapy in solid tumors has been hampered by multiple obstacles. Preclinical and clinical studies suggest that combinatorial immune checkpoint blockade and IDO1 inhibition provide durable therapeutic efficacy against cancer...

B cell maturation antigen (BCMA) has recently been identified as an important multiple myeloma (MM)-specific target for chimeric antigen receptor (CAR) T cell therapy. In CAR T cell therapy targeting CD19 for lymphoma, host immune anti-murine CAR responses limited the efficacy of repeat dosing and possibly long-term persistence. This clinically relevant concern can be addressed by generating a CAR incorporating a human single-chain variable fragment (scFv). We screened a human B cell-derived scFv phage display library and identified a panel of BCMA-specific clones from which human CARs were engineered...

Cancer immunotherapy, a new weapon against cancers by harnessing the patient's own immune system, potentiates an extended remission and possibly a cure for cancer. T cells genetically engineered with chimeric antigen receptor (CAR) vectors can specifically target the surface antigen of cancer cells and kill them in an MHC-independent manner. CD19 is extensively expressed on cancerous cells in B cell malignancies. To target this antigen, CAR T cells have gained great success in treating patients with B cell leukemia and lymphoma...

BACKGROUND: Multiple myeloma is usually fatal due to serial relapses that become progressively refractory to therapy. CD19 is typically absent on the dominant multiple myeloma cell population but may be present on minor subsets with unique myeloma-propagating properties. To target myeloma-propagating cells, we clinically evaluated autologous T cells transduced with a chimeric antigen receptor (CAR) against CD19 (CTL019). METHODS: Subjects received CTL019 following salvage high-dose melphalan and autologous stem cell transplantation (ASCT)...

Background: CD19-chimericantigen receptor (CAR) modified T cells (CD19-CAR T cells) have been well documented to possess potent anti-tumor properties against CD19-expressingleukemia cells. As a traditional medicine, metformin has been widely used to treat type II diabetes mellitus and more recently has become a candidate for the treatment of cancer. However, no report has revealed the direct effect of metformin on CD19-CAR T cell biological function and its underling mechanisms. Purpose: The purpose of this research was to explore the effect of metformin on CD19-CAR T cell biological function and the mechanisms involved...

Engineered T cell therapies show considerable promise in the treatment of refractory malignancies. Given the ability of engineered T cells to engraft and persist for prolonged periods along with unpredicted toxicities, incorporation of a suicide gene to allow selective depletion after administration is desirable. Rapamycin is a safe and widely available immunosuppressive pharmaceutical that acts by heterodimerization of FKBP12 with the FRB fragment of mTOR. The apical caspase caspase 9 is activated by homodimerization through its CARD domain...

Non-Hodgkin lymphoma (NHL) is the most common hematologic malignancy. More than 20,000 people in United States, more than 37,000 people in Europe and more than 199,000 people worldwide die of NHL every year. Recent advances in immunotherapeutic approaches for cancer have resulted in development of new classes of very effective immunotherapeutic approaches including chimeric antigen receptor T (CAR-T) cell therapy that are designed to bypass cancer immune evasion. Here, we review recent advances in CAR-T cell therapy for NHL...

Jordan Gauthier, Cameron J Turtle
T-cells engineered to express CD19-specific chimeric antigen receptors (CD19 CAR-T cells) can achieve high response rates in patients with refractory/relapsed (R/R) CD19+ hematologic malignancies. Nonetheless, the efficacy of CD19-specific CAR-T cell therapy can be offset by significant toxicities, such as cytokine release syndrome (CRS) and neurotoxicity. In this report of our presentation at the 2018 Second French International Symposium on CAR-T cells (CAR-T day), we describe the clinical presentations of CRS and neurotoxicity in a cohort of 133 adults treated with CD19 CAR-T cells at the Fred Hutchinson Cancer Research Center, and provide insights into the mechanisms contributing to these toxicities...
