Mustang Bio Reports Full-Year 2019 Financial Results and Recent Corporate Highlights
NEW YORK, March 16, 2020 (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 full year ended December 31, 2019.
Manuel Litchman, M.D., President and Chief Executive Officer of Mustang, said, “We are delighted by Mustang’s numerous accomplishments in 2019. We started off the year by executing a worldwide license agreement with Nationwide Children’s Hospital to develop MB-108, oncolytic virus C134, for the treatment of glioblastoma multiforme. In April, we announced the exciting New England Journal of Medicine publication of positive Phase 1/2 data from our partner, St. Jude Children’s Research Hospital (“St. Jude”), which demonstrated the curative potential of MB-107, a lentiviral gene therapy for X-linked severe combined immunodeficiency (“XSCID”), also known as bubble boy disease. We plan to transfer the MB-107 Investigational New Drug (“IND”) application from St. Jude to Mustang shortly. In August, the FDA accepted our first IND application to initiate a multi-center Phase 1/2 clinical trial of MB-102 (CD123-targeted CAR T cell therapy) in acute myeloid leukemia (“AML”), blastic plasmacytoid dendritic cell neoplasm (“BPDCN”) and high-risk myelodysplastic syndrome. We look forward to dosing our first patient soon, using MB-102 processed at our own cell processing facility.”
Dr. Litchman continued, “In 2019, we were also pleased that the FDA granted prestigious designations to our drug candidates, including the Regenerative Medicine Advanced Therapy (“RMAT”) designation to MB-107 and Orphan Drug Designations to MB-108 for the treatment of malignant glioma and to MB-102 for the treatment of AML. In addition, several Phase 1 trials were initiated with our collaborators during the year, including the MB-104 (CS1-targeted CAR T cell therapy) trial at City of Hope for multiple myeloma, the MB-105 (PSCA‐targeted CAR T cell therapy) trial at City of Hope for the treatment of prostate cancer, the MB-103 (HER2-targeted CAR T cell therapy) trial at City of Hope for the treatment of glioblastoma multiforme and of HER2-positive breast cancer with brain metastases, the MB-101 (IL13Rα2-targeted CAR T cell therapy) trial at City of Hope in combination with checkpoint inhibitors for the treatment of recurrent malignant glioma, and the MB-108, oncolytic virus C134, trial for the treatment of glioblastoma multiforme at the University of Alabama at Birmingham.”
Dr. Litchman concluded, “Mustang raised a total of $69 million throughout 2019, which enables us to continue to advance our gene and CAR T cell therapy programs. We look forward to maintaining this positive momentum through 2020, including several important data readouts anticipated in the second half of the year.”

- Net loss attributable to common stockholders was $46.4 million, or $1.29 per share, for the year ended December 31, 2019, compared to a net loss attributable to common stockholders of $30.7 million, or $1.14 per share, for 2018.
2019 and Recent Corporate Highlights:
- In February 2019, Mustang announced that it entered into an exclusive worldwide license agreement with Nationwide Children’s Hospital to develop oncolytic virus C134 (MB-108) for the treatment of glioblastoma multiforme. Mustang intends to combine the oncolytic virus with MB-101 (IL13Rα2-specific CAR T cell therapy) to potentially enhance efficacy in treating glioblastoma multiforme.
- In April 2019, Mustang announced that it had entered into a $20 million debt financing agreement with Horizon Technology Finance Corporation. Fifteen million of the $20 million loan was funded upon closing. The remaining $5 million may be funded upon Mustang’s achievement of certain predetermined milestones. In connection with the debt financing, Mustang issued Horizon warrants to purchase up to 288,184 shares of its common stock at an exercise price of $3.47 per share.
- Also in April 2019, the New England Journal of Medicine published St. Jude data from a Phase 1/2 clinical trial of MB-107, a lentiviral gene therapy, for the treatment of newly diagnosed infants under two years old with XSCID. Data demonstrated that the lentiviral gene therapy achieved normalization of T-cell numbers in all eight newly diagnosed infants to date and that disseminated infections resolved completely in all affected infants. Seven of the eight infants treated have developed normal IgM levels to date. Four of those seven infants have discontinued monthly infusions of intravenous immunoglobulin (IVIG) therapy to date. Three of those four infants who discontinued monthly IVIG infusions have responded to vaccines to date.
- In May 2019, Mustang completed an underwritten public offering, including the full exercise of the over-allotment option by the underwriters, that raised gross proceeds of $31.6 million, excluding underwriting discounts, commissions and other offering-related expenses.
- In May 2019, Mustang announced that City of Hope began enrolling patients with relapsed or treatment-resistant multiple myeloma in an innovative CS1-targeted CAR T cell therapy (MB-104) trial.
- Also in May 2019, the FDA granted Orphan Drug Designation to MB-108 (oncolytic virus C134) for the treatment of malignant glioma, a type of brain cancer with a median survival of less than 18 months.
- In July 2019, the FDA granted Orphan Drug Designation to MB-102 (CD123-targeted CAR T cell therapy) for the treatment of AML.
- In August 2019, Mustang announced that the FDA approved its IND application to initiate a multi-center Phase 1/2 clinical trial of MB-102 in AML, BPDCN and high-risk myelodysplastic syndrome.
- In August 2019, MB-107 was granted the RMAT designation by the FDA.
- Also in August 2019, Mustang entered into a license agreement with CSL Behring for the Cytegrity™ stable producer cell line, which will be used to produce the viral vector for the MB-107 lentiviral gene therapy program.
- Additionally in August 2019, the California Institute for Regenerative Medicine (CIRM) granted City of Hope $9.28 million to fund an ongoing Phase 1 clinical trial of MB-103 (HER2‐targeted CAR T cell therapy) for the treatment of HER2-positive breast cancer with brain metastases.
- In September 2019, Mustang announced that City of Hope opened and initiated patient treatments in a Phase 1 clinical trial of MB-105 (PSCA‐targeted CAR T cell therapy) for the treatment of prostate cancer.
- In October 2019, Mustang announced that City of Hope received $4.1 million in grant awards to initiate a clinical trial of MB-101 (IL13Rα2-targeted CAR T cell therapy) in combination with nivolumab (commercial name: Opdivo®) and ipilimumab (commercial name: Yervoy®) in patients with recurrent malignant glioma. The trial, which is now enrolling patients, is the first human study to combine IL13Rα2-targeted CAR T cell therapy with checkpoint inhibitors, as well as the first to locally deliver CAR T cells with combination treatment with systemic nivolumab treatment.
- Also in October 2019, Mustang announced that the first patient was dosed in a Phase 1 clinical trial to determine the safety and efficacy of MB-108 (oncolytic virus C134), an attenuated herpes simplex virus type 1, in recurrent glioblastoma multiforme.
- Updated Phase 1/2 clinical data for MB-107 were selected for oral and poster presentations at the 61st American Society of Hematology (“ASH”) Annual Meeting, which was held in December 2019. Data demonstrated that MB-107 preceded by low-dose busulfan conditioning continued to be well tolerated and resulted in the development of a functional immune system both in newly diagnosed infants with XSCID, as well as in older patients with XSCID who had received prior hematopoietic stem cell transplantation (HSCT). Also, the enhanced transduction procedure demonstrated more rapid recovery of NK cells and more rapid improvement in chronic norovirus infections vis-à-vis the original transduction procedure in older patients with XSCID who had received prior HSCT.
- Also at the 61st ASH Annual Meeting, Mustang’s collaborator Fred Hutchinson Cancer Research Center (“Fred Hutch”) presented a poster about the design of the ongoing Phase 1/2 clinical trial investigating the safety and efficacy of MB-106 (CD20-targeted CAR T cell therapy) for high-risk B-cell non-Hodgkin lymphomas.
- In February 2020, Mustang announced that the first subject treated with the optimized MB-106 (CD20-targeted, autologous CAR T cell therapy) manufacturing process, developed in collaboration between Mustang Bio and Fred Hutch, achieved a complete response at the lowest starting dose in an ongoing Phase 1/2 clinical trial. The trial is evaluating the safety and efficacy of MB-106 in subjects with relapsed or refractory B-cell non-Hodgkin lymphomas.
