Dual-Target CSPG4/GD2 CAR-NK Cells for Advanced Melanoma
brief summary
This is a first-in-human, open-label, multicenter phase 1/2 study evaluating the safety, feasibility, recommended phase 2 dose (RP2D), and preliminary antitumor activity of allogeneic dual-target CSPG4/GD2 CAR-NK cells (EBDTKN-401) after lymphodepleting chemotherapy in adults with unresectable or metastatic cutaneous melanoma or metastatic uveal melanoma whose disease has progressed after standard therapy
detailed description
The target-selection review favored CSPG4/GD2 because it gives the strongest melanoma-centered rationale across both cutaneous and uveal disease. EBDTKN-401 is an allogeneic donor-derived NK-cell product engineered with an OR-gate/tandem CAR recognizing CSPG4 or GD2 and an inducible caspase-9 safety switch. Part A uses 3+3 dose escalation to identify the RP2D. Part B evaluates the RP2D in expansion cohorts for cutaneous melanoma and uveal melanoma. Key secondary objectives are objective response, disease control, durability, progression-free survival, overall survival, CAR-NK persistence, and baseline biomarker-response relationships.
