• KRAS-specific Autologous TCR-T cell injection · EXPERIMENTAL · KRAS-specific Autologous TCR-T cell injection (5×10⁹, 1×10¹°, or 2×10¹° TCR-T cells per dose) with preconditioning lymphodepletion using Fludarabine and Cyclophosphamide, followed by IL-2 support

This is a single-center, open-label, single-arm, dose-escalation study aimed at evaluating the safety and preliminary efficacy of KRAS-specific autologous TCR-T cells in patients with advanced solid tumors harboring KRAS G12V mutation.
