Mustang Bio Announces Dosing of First Participant in Phase 1 Clinical Trial of MB-108 (Oncolytic Virus C134) to Treat Glioblastoma
First dose occurred in trial currently underway at the University of Alabama at Birmingham
NEW YORK, Oct. 24, 2019 (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, announced today that the first participant has been 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.
The first dosing took place at the University of Alabama at Birmingham (“UAB”), where the trial is led by James Markert, M.D., Ph.D., Chairman of the Department of Neurosurgery at UAB. Kevin Cassady, M.D., Principal Investigator for the Center for Childhood Cancer and Blood Diseases in the Abigail Wexner Research Institute at Nationwide Children’s Hospital (“Nationwide Children’s”), developed C134 in collaboration with Dr. Markert and advanced it for therapeutic use. Nationwide Children’s has exclusively licensed oncolytic virus C134 to Mustang.
The trial will enroll up to 24 participants who will receive escalating doses of MB-108. Safety will be assessed at each dose level before proceeding to the next. Other study objectives include characterizing MB-108’s activity after inoculation into the tumor, as well as the local and systemic immune responses to MB-108. The trial will also follow participants with MRI scans to monitor for potential clinical response to MB-108.
“Dosing the first participant in this trial represents an important step in evaluating MB-108’s potential to treat patients with glioblastoma,” Dr. Markert said. “We are pleased to have achieved this milestone and look forward to sharing more information as the trial progresses.”
Mustang and Nationwide Children’s intend to conduct a subsequent clinical trial that will investigate the combination treatment of MB-101 (IL13Rα2-specific CAR T) and MB-108 to potentially enhance efficacy in treating glioblastoma. Preclinical studies have demonstrated the synergistic potential of an oncolytic virus’ ability to induce an anti-tumor immune response when it is combined with CAR T therapy to target solid tumors.
Manuel Litchman, M.D., President and Chief Executive Officer of Mustang, said, “We congratulate UAB and Nationwide Children’s on dosing the first participant in this trial evaluating MB-108 in recurrent glioblastoma multiforme, which is one of the most common forms of malignant brain cancer in adults and is often difficult to treat. We are optimistic that MB-108 will provide a strong treatment option, particularly when combined with MB-101.”
In May, the U.S. Food and Drug Administration (“FDA”) granted Orphan Drug Designation to MB-108 for the treatment of malignant glioma.
