We look forward to transferring the MB-107 IND from St. Jude to Mustang in the fourth quarter of this year. Additionally, we are delighted that the U.S. Food and Drug Administration (FDA) accepted our first Investigational New Drug (IND) application to initiate a multi-center Phase 1/2 clinical trial of MB-102 (CD123 CAR T) in acute myeloid leukemia (AML), blastic plasmacytoid dendritic cell neoplasm (BPDCN) and high-risk myelodysplastic syndrome (MDS).”

Dr. Litchman continued, “Having raised a total of $69 million in the first half of 2019, we look forward to continuing to advance the development of our gene and CAR T cell therapy product candidates in the second half of 2019 and potentially reporting additional CAR T data in the fourth quarter.”
