Harnessing Myeloid Plasticity in CAR Macrophages for Solid Tumor Immunotherapy. (PubMed, Crit Rev Oncol Hematol)
Early clinical studies, including HER2-targeted CT-0508, demonstrate feasible manufacturing, acceptable safety, tumor infiltration, and immune remodeling, though objective efficacy remains limited. Major challenges include maintaining antitumor polarization, persistence, scalable manufacturing, target selection, and safety control. Continued optimization of CAR-M design and exploitation of myeloid plasticity will be critical to realizing their potential as solid tumor immunotherapy platforms.
