Treating Relapsed / Refractory (RR) AML with Biodegradable Anti-CD123 CAR Modified T Cells
(ASH 2017)
- P; "...Patients in cohort 1 were to receive up to three doses of CART123 cells (each dose being 4x106 cells/kg), and Cohort 2 patients were to receive up to six doses, with optional lymphodepleting chemotherapy (single dose of cyclophosphamide, 1g/m2) given 4 days prior to the first CART123 cell infusion...Severe CRS was treated with tocilizumab on 3 occasions in 2 patients, and all CRS episodes resolved within 1 day...In this pilot study, RNA CART123 cells had a biological effect as manifested by fever or CRS of varying severity in all patients. There was no clinically apparent vascular, neurological or hematological toxicity. However, no anti-tumor effect could be demonstrated."

Pre-Clinical Studies of Allogeneic Anti-CD123 CAR T-Cells for the Therapy of Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN)
(ASH 2017)
- P1; "...UCART123 product candidate is based on genetically modified allogeneic T-cells (derived from healthy donors, so-called “off the shelf”) containing an anti-CD123 CAR (CD123 scFv-41BB-CD3z) and a RQR8 depletion ligand that confers susceptibility to rituximab...These results demonstrate pre-clinical proof-of principle of high anti-BPDCN activity of allogeneic UCART123 cells. A phase I trial of UCART123 in BPDCN is opened for enrollment (NCT03203369)."

Preclinical efficacy of allogeneic anti-CD123 CAR T-cells for the therapy of blastic plasmacytoid dendritic cell neoplasm (BPDCN)
(AACR 2018)
- P1; "Nearly 100% of patients with BPDCN overexpress CD123, and targeting CD123 emerged as an attractive therapeutic target given its differential expression on BPDCN cell surface.UCART123 product (Cellectis) uses genetically modified allogeneic T-cells (derived from healthy donors, so-called off the shelf) containing an anti-CD123 CAR and a RQR8 depletion ligand that confers susceptibility to rituximab. However, loss of CD123 through diverse genetic mechanisms could lead to escape from UCART123 therapy and cause relapses. A phase I trial of UCART123 in BPDCN is opened for enrollment."

Prediction of immunotherapy outcome by multimodal assessment of minimal residual disease and persistence of allogeneic anti-CD123 CAR T-cells (UCART123) in pre-clinical models of acute myeloid leukemia
(AACR 2018)
- "Importantly, when mutated NPM1 levels became elevated with simultaneous loss of UCART123, relapse was evident by MFC in PB in subsequent time-points (2 out 20 mice, all at 1x106 dose, ~180 days) re-infusion of UCART123 cells resulted in effective elimination of AML.Taken together, we have demonstrated that simultaneous monitoring of disease and UCART123 cells provides valuable insight into the kinetics and effectiveness of UCART123 cells. Currently, we have implemented the ddPCR assay in the phase I clinical trial of UCART123 in AML allowing to simultaneously detect UCART123 cells and blasts in peripheral blood of NPM1 mutant AML patients."

Ruxolitinib Prevents Cytokine Release Syndrome after CART Cell Therapy without Impairing the Anti-Tumor Effect in a Xenograft Model
(ASH 2016)
- "NSG-S mice bearing primary AML were treated with CART123 and randomized to receive different doses of ruxolitinib (30, 60, or 90 mg/kg) or vehicle by oral gavage twice a day. While the use of the anti-IL6 receptor antibody tocilizumab with or without steroids can usually reverse this syndrome, there is concern that the early introduction of immunosuppressive medications could impair the anti-tumor activity and therefore most investigators currently reserve tocilizumab as therapy for severe (grade 3-4) CRS. These findings provide a useful platform for the future study of CRS prevention and treatment modalities. These experiments indicate that ruxolitinib could also be combined with CART cell therapy for the prevention of CRS in patients identified to be at high risk for the development of CRS."

Efficacy Proof of Concept for Allogeneic CD123 Targeting CAR T-Cells Against Primary Blastic Plasmacytoid Dendritic Cell Neoplasm (BPDCN): Efficient Control of Tumor Progression in PDX Model and Potential Loss of CD123 Expression in Relapsed Disease
(ASH 2019)
- "UCART123v1 is an allogeneic “off the shelf” product composed of genetically modified T-cells expressing an anti-CD123 CAR and a RQR8 depletion ligand, which confers susceptibility to rituximab. However, CD123 loss was observed in one PDX model harboring a TP53 deletion. These results provide preclinical proof-of-principle that UCART123v1 cells have potent anti-BPDCN activity, and indicate potential mechanisms leading to antigen loss and disease relapse."

IFN-γ and TNF-α aggravate endothelial damage caused by CD123-targeted CAR T cell.

- " In summary, this study identified that the expression of CD123 on endothelial cells could be upregulated when co-cultured with CART123. Furthermore, IFN-γ and TNF-α could aggravate endothelial damage caused by CART123 in vitro."
