Orphan Drug Designation Granted by FDA for MB-101 to Treat GBM and Astrocytomas 

Manuel Litchman, M.D., President and Chief Executive Officer of Mustang, said, “We are thrilled that MB-101 received Orphan Drug Designation on time and with a designation that is broader than the indication proposed. The Orphan Drug Designation for MB-101, coupled with the Orphan Drug Designation granted previously for MB-108, is strong validation for our science, as we hope to advance MB-101, in combination with MB-108, as a potential treatment option for patients living with malignant glioma, including patients with recurrent glioblastoma (“GBM”) and high-grade astrocytomas. Our novel therapeutic strategy, combining our MB-101 CAR-T cell therapy with our MB-108 oncolytic virus, leverages MB-108 to reshape the tumor microenvironment (“TME”) to make cold tumors “hot,” thereby potentially improving the efficacy of MB-101 CAR-T cell therapy. This progress demonstrates our dedication to exploring new possibilities for improving outcomes in patients with challenging-to-treat cancers.”
