EXTH-62. STEM CELL DELIVERY OF ONCOLYTIC ADENOVIRUS DNX-2401 FOLLOWING SURGICAL RESECTION FOR THE TREATMENT OF GLIOBLASTOMA

BACKGROUND The oncolytic virus DNX-2401 (Delta-24-RGD) is a novel treatment of GBM. While prior studies have examined intratumoral injection of DNX-2401 into recurrent GBM, the potential of delivering DNX-2401 into the surgical resection cavity using tumor-tropic human mesenchymal stem cells (MSCs) has not been evaluated. We hypothesize that exploiting a fibrin-based scaffold for transplanting MSCs loaded with DNX-2401 (MSCs-DNX-2401) into the...
