Mustang Bio Reports Second Quarter 2021 Financial Results and Recent Corporate Highlights

August 16, 2021 GMT

WORCESTER, Mass., Aug. 16, 2021 (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 financial results and recent corporate highlights for the second quarter ended June 30, 2021.

Manuel Litchman, M.D., President and Chief Executive Officer of Mustang, said, “In the first half of 2021, Mustang continued to progress the development of our CAR T therapies across multiple cancers, as well as our lentiviral gene therapies for the treatment of X-linked severe combined immunodeficiency (“XSCID”), also known as bubble boy disease. We are encouraged by the updated interim MB-106 CD20-targeted, autologous CAR T data presented at the European Hematology Association 2021 Virtual Congress (“EHA2021”) in June. The data presented showed a favorable safety profile and compelling clinical activity, with a 93% overall response rate and 67% complete response rate in patients with high-risk B-cell non-Hodgkin lymphomas (“B-NHL”) and chronic lymphocytic leukemia (“CLL”) who were treated with our modified cell manufacturing process. Additionally, the U.S. Food and Drug Administration (“FDA”) accepted Mustang’s Investigational New Drug (“IND”) application to initiate a multicenter Phase 1/2 clinical trial investigating the safety, tolerability and efficacy of MB-106 for relapsed or refractory B-NHL and CLL. We look forward to enrolling the first patient in the trial later this quarter and to further advancing MB-106 for patients with B-NHL and CLL.”

Dr. Litchman continued, “Last week, we announced an exclusive license agreement for a novel in situ CAR T technology that may be able to transform the administration of CAR T therapies, facilitating how the treatments are delivered to patients, with the potential to be used broadly as an off-the-shelf therapy. With this collaboration with the Mayo Clinic, we gain access to an innovative platform technology that we hope will become the discovery engine for a whole new generation of CAR T products at Mustang. We also announced that the first patient was dosed at City of Hope in a clinical trial to establish the safety and feasibility of administering MB-101 (autologous IL13Rα2-targeted CAR T cells) to patients with leptomeningeal brain tumors. On the regulatory front, we are delighted that the European Medicines Agency (“EMA”) recently granted Priority Medicines (“PRIME”) designation to MB-107, our lentiviral gene therapy for the treatment of XSCID in newly diagnosed infants. We anticipate enrolling the first patient in the pivotal Mustang-IND MB-107 trial for newborns with XSCID shortly and also expect to file an IND for a pivotal MB-207 trial in previously transplanted XSCID patients later this quarter. We look forward to continuing to provide updates on our CAR T and gene therapy clinical programs in the second half of the year.”

Recent Corporate Highlights:

  • In May 2021, Mustang announced that the FDA approved its IND application to initiate a multicenter Phase 1/2 clinical trial investigating the safety and efficacy of MB-106, a CD20-targeted CAR T for relapsed or refractory B-NHL and CLL.
  • Also in May 2021, Mustang announced that the first patient was dosed at City of Hope in a clinical trial to establish the safety and feasibility of administering MB-101 (autologous IL13Rα2-directed CAR T cells) to patients with leptomeningeal brain tumors (e.g., glioblastoma, ependymoma or medulloblastoma).
  • In June 2021, Mustang announced MB-106 CD20-targeted CAR T data were presented at EHA2021. Dr. Mazyar Shadman of Fred Hutchinson Cancer Research Center presented updated interim data from the ongoing Phase 1/2 clinical trial for B-NHL and CLL, which showed a favorable safety profile and compelling clinical activity with a 93% overall response rate and 67% complete response rate in patients treated with the modified cell manufacturing process.
  • Also in June 2021, Mustang hosted a key opinion leader webinar featuring a presentation from Dr. Shadman, who discussed interim results from the ongoing Phase 1/2 clinical trial investigating the safety and efficacy of MB-106 CD20-targeted CAR T for B-NHL and CLL. A replay of the webinar can be found here.
  • Additionally in June 2021, Mustang announced that it has been awarded a $300,000 Massachusetts Life Sciences Center tax incentive based on a hiring commitment of 20 net new full-time equivalent employees for calendar year 2021 and retaining that headcount level through 2025.
  • Earlier this month, Mustang announced that the EMA granted PRIME designation to MB-107, its lentiviral gene therapy for the treatment of XSCID in newly diagnosed infants.
  • Last week, Mustang announced an exclusive license agreement with Mayo Clinic for a novel technology that may be able to transform the administration of CAR T therapies and has the potential to be used as an off-the-shelf therapy.
