A Nature Materials study describes mRNA-loaded LNPs that reprogram tumor-associated macrophages into Claudin18.2-targeting CAR macrophages. The lipid formulation also promotes TREM2 internalization and degradation, reshaping immune responses. The original abstract reports tumor suppression and longer survival with PD-1 blockade in mice, plus ex vivo patient-sample findings. These findings do not demonstrate clinical efficacy in treated patients.
CSPC announced initiation of the first Chinese center for SYS6055-003, a Phase 1/2 trial in relapsed or refractory B-cell non-Hodgkin lymphoma. SYS6055 uses lentiviral vectors to generate CD19-targeting CAR-T cells in vivo. The company said recruitment and screening are underway following October clinical-trial authorization. Center initiation does not establish patient dosing, efficacy, or marketing approval.
Azalea reported SITC preclinical findings for its dual-vector in vivo CAR-T platform, combining targeted CRISPR-Cas9 delivery with AAV-mediated CAR insertion at the TRAC locus. The company described leukemia clearance and protection after tumor rechallenge in selected mouse groups, plus dual-antigen and armored designs. These are animal findings, not evidence of efficacy or safety in patients.
