Emerging advances in CAR-T therapy for solid tumors: latest clinical trial updates from 2025 ASCO annual meeting

Chimeric antigen receptor T-cell (CAR-T) therapy has demonstrated a transformative impact in hematologic malignancies and offers a promising strategy to offer new hope for patients with solid tumors who have failed multiple lines of treatment. The clinical application of CAR-T therapy in solid tumors, however, still has challenges, including tumor heterogeneity, an immunosuppressive tumor microenvironment, and safety concerns. These hurdles have mean that CAR-T therapy has become both a focal point and a pivotal trend in contemporary clinical research. The American Society of Clinical Oncology (ASCO) Annual Meeting serves as a premier venue for unveiling groundbreaking clinical data. In this review, we highlight the main phase I clinical trial advances in CAR-T therapy for solid tumors presented at the 2025 ASCO Meeting.
