In vivo CAR-T coverage and verification boundaries

67 public entity records, including 53 disclosed in vivo CAR-T developers or acquired platforms, plus 4 enabling partners, 5 adjacent platforms, 1 historical platform, and 4 other editing companies.

Entity counts are not independent program counts or a claim of 53 independently operating biotechs. Shared lineages and partnerships, including GRIT/Vivacta and Orna/Simnova, are identified. ReNAgade and Myeloid are not counted again.

Broad English and Chinese discovery searches followed by company pipelines, company-issued announcements, regulatory filings, and original research/meeting abstracts. Company claims are attributed; no inference of efficacy from registration, IND clearance, orphan status, or ex vivo programs. Publicly disclosed companies only; not a guarantee of exhaustive worldwide coverage.

An inherent T cell-activating mRNA delivery carrier for in vivo CAR T generation

The authors report a polymer–lipid carrier that combines mRNA delivery with T-cell activation without an antibody targeting ligand. The study links the carrier to metabolic signaling and evaluates CAR expression and activity in preclinical cancer and fibrosis models. These findings do not establish safety or benefit in patients.
