August 10, 2020
WORCESTER, Mass., Aug. 10, 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 second quarter ended June 30, 2020.
Manuel Litchman, M.D., President and Chief Executive Officer of Mustang, said, “Mustang made progress on multiple fronts during the second quarter of 2020. In June, we raised gross proceeds of approximately $37.2 million in an underwritten public offering of common stock. On the clinical front, we continued to advance our robust pipeline of gene and CAR T cell therapy programs. Notably, we began enrolling patients in a Phase 1/2 clinical trial of MB-102 (CD123-targeted CAR T cell therapy) under our own Investigational New Drug (“IND”) application for relapsed or refractory blastic plasmacytoid dendritic cell neoplasm, acute myeloid leukemia and high-risk myelodysplastic syndrome. We look forward to continued progress throughout the second half of this year, as we expect to initiate our pivotal MB-107 and MB-207 lentiviral gene therapy programs for newly diagnosed infants and previously transplanted patients with X-linked severe combined immunodeficiency (“XSCID”) and to disclose additional data from our MB-106 CD20-targeted CAR T cell therapy program.”
Recent Corporate Highlights:
In June 2020, Mustang raised gross proceeds of approximately $37.2 million in an underwritten public offering of common stock, including the exercise of the underwriter’s option.
In May 2020, City of Hope presented two posters pertaining to MB-104, an innovative CS1 CAR T cell therapy, at the virtual 23rd Annual Meeting of the American Society of Gene & Cell Therapy (“ASGCT”).
Also in May 2020, Mustang submitted an IND application to the U.S. Food and Drug Administration (“FDA”) to initiate a multi-center Phase 2 clinical trial of MB-107 in newly diagnosed infants with XSCID who are under the age of two. The trial is expected to enroll 10 patients who, together with 15 patients enrolled in the current multi-center trial led by St. Jude Children’s Research Hospital, will be compared with 25 matched historical control patients who have undergone hematopoietic stem cell transplant (“HSCT”). The primary efficacy endpoint will be event-free survival. The initiation of this trial is currently on hold pending CMC clearance by the FDA, which is expected in early Q4 2020. Mustang is targeting topline data from this trial in the second half of 2022.
Mustang expects to file an IND in the fourth quarter of 2020 for a registrational multi-center Phase 2 clinical trial of its lentiviral gene therapy in previously transplanted XSCID patients. This product will be designated MB-207. Mustang anticipates enrolling 20 patients and comparing them to matched historical control patients who have undergone a second HSCT. The company is targeting topline data from this trial in the second half of 2022.
In the ongoing Phase 1 trial of MB-105, a PSCA-directed CAR T administered systemically to patients with PSCA-positive castration resistant prostate cancer, at City of Hope, the first patient to receive the therapy following a standard CAR T conditioning regimen experienced a significant reduction in his prostate-specific antigen (“PSA”) at day 28. This PSA response was associated with radiographic improvement of the patient’s metastatic disease.
In April 2020, Mustang announced that the European Medicines Agency (“EMA”) granted Advanced Therapy Medicinal Product (“ATMP”) classification to MB-107 for the treatment of XSCID.
