(“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 the U.S. Food and Drug Administration (“FDA”) has granted Orphan Drug Designation to MB-106, Mustang’s CD20-targeted, autologous CAR T cell therapy for the treatment of Waldenstrom macroglobulinemia (“WM” or “Waldenstrom”), a rare type of B-cell non-Hodgkin lymphoma (“B-NHL”). MB-106 is being developed in a collaboration between Mustang and Fred Hutchinson Cancer Center (“Fred Hutch”) to treat patients with relapsed or refractory B-NHLs and chronic lymphocytic leukemia (“CLL”). The FDA grants Orphan Drug Designation to drugs and biologics that are intended for the safe and effective treatment, diagnosis or prevention of rare diseases or disorders that affect fewer than 200,000 people in the U.S. Orphan Drug Designation provides certain incentives, such as tax credits toward the cost of clinical trials upon approval and prescription drug user fee waivers. If a product receives Orphan Drug Status from the FDA, that product is entitled to seven years of market exclusivity for the disease in which it has Orphan Drug designation, which is independent from intellectual property protection. Manuel Litchman, M.D., President and Chief Executive Officer of Mustang, said, “We are very pleased to receive Orphan Drug Designation from the FDA, as it is an important regulatory milestone for Mustang’s MB-106 program for the treatment of Waldenstrom macroglobulinemia, a rare B-NHL with a significant unmet medical need. We look forward to dosing the first patient in our multicenter Phase 1/2 clinical trial evaluating the safety and efficacy of MB-106 for relapsed or refractory B-NHL and CLL under Mustang’s IND shortly. In the Phase 1 portion of this trial, MB-106 dose escalation will proceed in three separate arms, and Waldenstrom patients will be included in the indolent lymphoma arm in parallel with accrual of patients to the aggressive lymphoma and CLL arms....
