WORCESTER, Mass., May 11, 2023 (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 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”), will be presented at the European Hematology Association (“EHA2023”) Hybrid Congress taking place June 8-11, 2023, in Frankfurt, Germany and at the International Conference on Malignant Lymphoma (“ICML”) taking place June 13-17, 2023, in Lugano, Switzerland.

Both presentations will be given by Mazyar Shadman, M.D., M.P.H., Associate Professor and physician at Fred Hutchinson Cancer Center (“Fred Hutch”) and University of Washington. MB-106 is being developed in a collaboration between Mustang and Fred Hutch.

“As we continue to progress our CD20-targeted CAR T cell therapy program, we look forward to the upcoming presentations highlighting data from the Phase 1/2 study of MB-106 taking place at Fred Hutch. MB-106 has been demonstrating compelling clinical activity and a favorable safety profile in the ongoing Phase 1/2 trial at Fred Hutch for patients with follicular lymphoma and Waldenstrom macroglobulinemia, a rare type of indolent B-NHL,” said Manuel Litchman, M.D., President and Chief Executive Officer of Mustang. “Looking ahead, Mustang plans to provide a data update in the near future from our Phase 1/2 clinical trial evaluating the safety and efficacy of MB-106 in a multicenter setting.”
