CD19/CD22 bivalent CAR T cells in children, adolescents and young adults with B-ALL: final phase 1 trial results. (PubMed, J Immunother Cancer)
Following a protocol amendment to evaluate the efficacy of siltuximab as a first-line treatment of CRS, one patient received siltuximab with full resolution of CRS after two doses without needing additional anti-cytokine-directed therapies...This extended experience demonstrates that CD19.22.BBζ CAR T-cell therapy is safe and clinically active, particularly as a bridge to HSCT. Non-response was confined to patients with non-CNS EMD, highlighting the persistent challenge of effectively targeting EMD and informing the design of future CAR constructs.Trial registration numberNCT03448393.

Loss of cold shock domain-containing protein E1 (CSDE1) function enhances mRNA stability of interleukin-6 and promotes malignant transformation in endometrial cancer cells. (PubMed, Cell Commun Signal)
These findings establish CSDE1 as a novel tumor suppressor in EC and elucidate a previously unrecognized post-transcriptional CSDE1-IL-6 regulatory axis. By linking RBP-mediated mRNA stability to oncogenic inflammatory signaling, our study provides critical insights into the molecular drivers of EC progression. Furthermore, we identify the IL-6 signaling pathway as a significant therapeutic vulnerability that could be exploited to treat CSDE1-deficient EC.

Early intervention for high-risk smoldering multiple myeloma (SMM). (PubMed, Cochrane Database Syst Rev)
Early intervention with daratumumab may reduce the risk of disease progression and mortality in people with high-risk SMM. The evidence on the risk of adverse events with daratumumab is very uncertain. For immunomodulatory agents, the available evidence is of very low certainty, partly due to conflicting results, so we are unable to draw conclusions about their effects. There is insufficient evidence to support the use of older agents like alkylating agents or cytokine inhibitors. The decision to initiate early treatment in high-risk SMM requires a careful, individualized risk-benefit assessment and shared decision-making.

Case Report: Targeted interleukin-6 blockade by siltuximab for cytokine release syndrome control and infection limitation in thirteen patients treated with bi-specific T-cell engagers. (PubMed, Front Immunol)
This approach was associated with only three grade 1-2 infections, indicating a favorable safety profile. These preliminary results support the design of a prospective multicenter study to evaluate the feasibility of home-based BiTE administration, integrating point-of-care testing, a digital health platform, and 24/7 remote monitoring via a dedicated call center, within a comprehensive medico-economic framework.
