CSPG4-CAR.CIK significantly delayed or reversed tumor growth in three STS xenograft models (leiomyosarcoma, undifferentiated pleomorphic sarcoma, and fibrosarcoma). Tumor growth inhibition persisted for up to 2 weeks following the last administration of CSPG4-CAR.CIK. This study has shown that CSPG4-CAR.CIK effectively targets multiple STS histotypes and in immunodeficient mice. These results provide a strong rationale to translate the novel strategy we have developed into a clinical setting.

In early clinical trials, inhibitors targeting G12C-mutant KRAS have achieved responses in some patients with NSCLC. Possible intrinsic and acquired resistance mechanisms to KRAS G12C inhibitors are not fully elucidated and will likely become important to identify. To identify potential resistance mechanisms, we defined the sensitivity of a panel of KRAS G12C-mutant lung cancer cell lines to a KRAS G12C inhibitor, AMG510. Gene set enrichment analyses were performed to identify pathways related to the sensitivity, which was further confirmed biochemically. In addition, we created two cell lines that acquired resistance to AMG510 and the underlying resistance mechanisms were analyzed. KRAS expression and activation were associated with sensitivity to KRAS G12C inhibitor. Induction of epithelial-to-mesenchymal transition (EMT) led to both intrinsic and acquired resistance to KRAS G12C inhibition. In these EMT-induced cells, PI3
