Mustang Bio Announces MB-106 CD20-Targeted CAR T Data Selected for Presentation at the 2022 Tandem Meetings I Transplantation & Cellular Therapy Meetings of ASTCT and CIBMTR

WORCESTER, Mass., Jan. 07, 2022 (GLOBE NEWSWIRE) -- Mustang Bio, Inc. (“Mustang”) (NASDAQ: MBIO), a clinical-stage biopharmaceutical company focused on translating today’s medical breakthroughs in cell and gene therapies into potential cures for hematologic cancers, solid tumors and rare genetic diseases, today announced that interim Phase 1/2 data on MB-106, a CD20-targeted, autologous CAR T cell therapy for patients with relapsed or refractory B-cell non-Hodgkin lymphomas (“NHL”) and chronic lymphocytic leukemia (“CLL”), have been selected for a poster presentation at the 2022 Tandem Meetings I Transplantation & Cellular Therapy Meetings of the American Society of Transplantation and Cellular Therapy (“ASTCT”) and Center for International Blood & Marrow Transplant Research (“CIBMTR”), taking place February 2 – 6, 2022 in Salt Lake City, Utah (“2022 Tandem Meetings”). MB-106 is being developed in a collaboration between Mustang and Fred Hutchinson Cancer Research Center (“Fred Hutch”).

Manuel Litchman, M.D., President and Chief Executive Officer of Mustang, said, “The compelling clinical activity and favorable safety profile that MB-106 continues to demonstrate in the ongoing Phase 1/2 trial at Fred Hutch highlight its potential as an outpatient therapy for patients with relapsed or refractory B-cell non-Hodgkin lymphomas and chronic lymphocytic leukemia. We look forward to the updated data that will be presented by Fred Hutch at the 2022 Tandem Meetings, in particular for patients with diffuse large B cell lymphoma and Waldenstrom’s macroglobulinemia. We also look forward to advancing our MB-106 CD20-targeted CAR T cell therapy program towards a multicenter trial under Mustang’s IND in the current quarter.”

Details of the presentation are as follows:

Title: High Efficacy and Low Toxicity of MB-106, a Third Generation CD20 Targeted CAR-T for Treatment of Relapsed/Refractory B-NHL and CLL
Poster Number: 225
Dates and Times: Thursday, February 3, 6:45 pm to 8:15 pm and Saturday, February 5, 6:15 pm to 7:45 pm
Presenter: Mazyar Shadman, M.D., M.P.H., Associate Professor, Clinical Research Division, Fred Hutch, Seattle, WA; Physician at Seattle Cancer Care Alliance; Associate Professor, Division of Medical Oncology, University of Washington School of Medicine

About MB-106 (CD20-targeted CAR T Cell Therapy)
CD20 is a membrane-embedded surface molecule which plays a role in the differentiation of B-cells into plasma cells. The CAR T was developed by Mustang’s research collaborator, Fred Hutch, in the laboratories of the late Oliver Press, M.D., Ph.D., and Brian Till, M.D., Associate Professor in the Clinical Research Division at Fred Hutch, and exclusively licensed to Mustang in 2017. The lentiviral vector drug substance used to transduce patients’ cells to create the MB-106 drug product produced at Fred Hutch has been optimized as a third-generation CAR derived from a fully human antibody, and MB-106 is currently in a Phase 1/2 open-label, dose-escalation trial at Fred Hutch in patients with B-NHLs and CLL. The same lentiviral vector drug substance produced at Fred Hutch will be used to transduce patients’ cells to create the MB-106 drug product produced at Mustang Bio’s Worcester, MA, cell processing facility for administration in the planned multicenter phase 1/2 clinical trial to be initiated shortly under Mustang Bio’s IND. It should be noted that Mustang Bio has introduced minor improvements to its cell processing to facilitate eventual commercial launch of the product. In addition, prior to commercial launch, Mustang Bio will replace the Fred Hutch lentiviral vector drug substance with vector produced at a commercial manufacturer. Additional information on the trial can be found at http://www.clinicaltrials.gov using the identifier NCT03277729.
