Epstein-Barr virus (EBV) reactivation in immunocompromised patients and post-transplantation is associated with morbidity, mortality and with the onset of a variety of malignant diseases. Adoptive T-cell therapies have emerged as promising therapeutic options, but post-transplant immunosuppression jeopardizes the protective anti-EBV immune surveillance by adoptively transferred T cells.Using an all-in-one CRISPR/Cas-mediated approach, we inserted an anti-EBV (gp350) CAR into the T-cell receptor (TRAC) locus and simultaneously knocked-out the glucocorticoid receptor (GR) on a good manufacturing practice (GMP)-compatible platform.CAR knock-in (CARKI) was confirmed in primary human T cells on genetic and on protein level with a mean efficiency of 41%.

The KIT/c-KIT proto-oncogene is frequently over-expressed in Merkel cell carcinoma (MCC), an aggressive skin cancer commonly caused by Merkel cell polyomavirus (MCPyV). Here, we demonstrated that truncated MCPyV-encoded large T-antigen (LT) suppressed macroautophagy/autophagy by stabilizing and sequestering KIT in the paranuclear compartment via binding VPS39. [...]

Adoptive cellular therapy (ACT) is a promising treatment approach aiming at enhancing T-cell antitumor immune response. ACT includes tumor-infiltrating lymphocytes, chimeric antigen receptor (CAR) and T-cell receptor gene-modified T cells. [...]

FOLR1 is heterogeneously overexpressed in epithelial ovarian cancer. We examined the combined effects of the anti-FOLR1 antibody-drug conjugate (IMGN853) with other drugs, including topotecan, anti-VEGF-A antibody, and olaparib. [...]

Effective cancer therapy involves initiation of a tumor-specific immune response. Consequently, the interest in oncolytic viruses (OV) capable of triggering immunogenic cell death has sparked in recent years. [...]

Background/Objectives: The oncofetal membrane protein Claudin 6 (CLDN6) is an attractive target for T cell-based therapies. There is a lack of detailed analyses on the age-dependent expression of CLDN6 in normal tissues is lacking, which limits the expansion of CLDN6 CAR-T cell clinical trials to pediatric populations. [...]

Non-invasive motor mapping with navigated transcranial magnetic stimulation (nTMS) is an established diagnostic tool to identify spatial relationships between functional and tumor areas and to characterize motor excitability. Recently, nTMS has been used to analyze the impact of different brain tumor entities on motor excitability. [...]

To examine separate and joint associations between pre-existing cardiometabolic comorbidities and all cause and cause specific mortality in adults with cancer.Multinational cohort study.Seven European countries from the European Prospective Investigation into Cancer and Nutrition (EPIC) study, 1 January 1992 to 31 December 2013.26 987 participants (54% women) who developed a first primary cancer. 2113 had a history of type 2 diabetes, 1529 had a history of cardiovascular disease, and 531 had a history of both, at the time of diagnosis of cancer.Hazard ratios (95% confidence intervals, CIs) for associations between pre-existing cardiometabolic comorbidities and all cause and cause specific mortality in adults with cancer, estimated with multivariable Cox regression models. [...]

We investigated SAR441000 (mixture of four mRNAs encoding interleukin [IL]-12, single chain interferon [IF]-α-2b, granulocyte-macrophage colony-stimulating factor, and IL-15 sushi domain) alone or in combination with cemiplimab in patients with advanced solid tumors.SAR441000 was intratumorally administered weekly in a 4-week cycle in monotherapy and in a 3-week cycle at a pre-defined dose level (DL) with 350 mg cemiplimab (intravenously) every 3 weeks in combination therapy. The primary objective was to determine maximum tolerated or maximum administered dose (MAD), overall safety, tolerability, and objective response rate of SAR441000.We enrolled 77 patients previously treated with anti-cancer therapies (escalation monotherapy: N=21; escalation combination: N=15; and expansion combination [PD-1 refractory melanoma]: N=41).
