Targeting GPC2 on intraocular and CNS metastatic retinoblastomas with local and systemic delivery of CAR T-cells

Retinoblastoma is the most common intraocular malignancy in children. Although new chemotherapeutic approaches have improved ocular salvage rates, novel therapies are required for patients with refractory intraocular and metastatic disease. Chimeric antigen receptor (CAR) T-cells targeting glypican-2 (GPC2) are a potential new therapeutic strategy.
