Tiziana Life Sciences Announces Positive Results in Treating Spinal Cord Injury With Nasal Anti-CD3

NEW YORK, Jan. 23, 2025 (GLOBE NEWSWIRE) -- Tiziana Life Sciences, Ltd. (Nasdaq: TLSA) (“Tiziana” or the “Company”), a biotechnology company developing breakthrough immunomodulation therapies with its lead development candidate, intranasal foralumab, a fully human, anti-CD3 monoclonal antibody, today announced results from studies using a nasal anti-CD3 monoclonal antibody in traumatic spinal cord injury (SCI). Spinal cord injury is a devastating global health issue with profound implications for both mortality and morbidity. The inflammatory response mediated by microglia is a critical component in the pathogenesis of SCI. In these studies, the preclinical model was subjected to a spinal cord injury and then was treated with nasal anti-CD3, resulting in notable advancements in motor functions. Furthermore, spinal cord injuries (SCIs) are complex neurotraumatic wounds affecting military Service members, their families, Veterans, and the general population. These are serious injuries with long-term consequences requiring lifelong care. It is estimated that about 300,000 individuals are living with an SCI, and this number continues to grow as over 17,000 new cases occur in the U.S. each year (https://cdmrp.health.mil/scirp/default). “Our pre-clinical findings underscore the pivotal role of nasal anti-CD3 in modulating microglial inflammation associated with spinal cord injury,” Dr. Howard Weiner, Chairman of Tiziana’s Scientific Advisory Board and co-director of the Ann Romney Center for Neurologic Diseases at Brigham and Women’s Hospital, a founding member of Mass General Brigham healthcare system. Dr. Saef Izzy, Associate Professor of Neurology at Harvard Medical School, commented, “Treatment with nasal anti-CD3 not only dampened microglial activation but also led to marked improvements in motor function among the injured models. These results hold promise for a transformative therapeutic approach in SCI.” CEO of Tiziana Life Sciences, Ivor Elrifi, highlighted the strategic implications, stating, "We are swiftly advancing towards expanding our nasal foralumab technology from successful applications in neurologic diseases like secondary progressive multiple sclerosis to now encompass spinal cord injury. This underscores our commitment to pioneering treatments that address significant unmet medical needs." About Foralumab Foralumab is a fully human anti-CD3 monoclonal antibody that has been shown to stimulate T regulatory cells when dosed intranasally. Intranasal foralumab is currently being studied in a Phase 2a, randomized, double-blind, placebo-controlled, multicenter, dose-ranging trial in patients with non-active secondary progressive multiple sclerosis (NCT06292923). Activated T cells play an important role in the inflammatory process. Foralumab, the only fully human anti-CD3 monoclonal antibody (mAb) currently in clinical development, binds to the T cell receptor and dampens inflammation by modulating T cell function, thereby suppressing effector features in multiple immune cell subsets. This effect has been observed in patients with COVID and with multiple sclerosis, as well as in healthy normal subjects. Immunomodulation by nasal anti-CD3 mAb represents a novel avenue for treatment of neuroinflammatory and neurodegenerative human diseases.[1],[2] About Tiziana Life Sciences Tiziana Life Sciences is a clinical-stage biopharmaceutical company developing breakthrough therapies using transformational drug delivery technologies to enable alternative routes of immunotherapy. Tiziana’s innovative nasal approach has the potential to provide an improvement in efficacy as well as safety and tolerability compared to intravenous (IV) delivery.
