Data from Ph 1 Trial of MB-101 IL13Rα2-targeted CAR T-Cells in High-Grade Glioma published

Manuel Litchman, M.D., President and Chief Executive Officer of Mustang, said, “MB-101 has demonstrated compelling therapeutic potential, including delivering unprecedented complete responses in two high-grade glioma patients; the first patient who achieved a complete response was published in The New England Journal of Medicine. These two patients treated solely with MB-101 both had high levels of intratumoral CD3+ T-cells pre-therapy (i.e., “hot” tumors) and achieved complete responses lasting 7.5 and 66+ months, respectively. This trial has led to several other studies using MB-101, including supporting our upcoming novel combination clinical trial of MB-109 [MB-101 (IL-13Rα2 targeted CAR T-cell therapy) + MB-108 (HSV-1 oncolytic virus)] to improve treatment of recurrent GBM and high-grade astrocytoma. The combination leverages initial treatment with MB-108 to reshape the tumor microenvironment and make immunologically “cold” tumors “hot,” thereby potentially enabling the MB-101 CAR T-cell therapy to achieve efficacy equivalent to that seen in intrinsically “hot” tumors in this City of Hope Phase 1 trial.”
