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 that a review article titled “Immune mechanisms and shared immune targets in neurodegenerative diseases” was published in Nature Reviews Neurology, highlighting the therapeutic potential of intranasal foralumab in various neurodegenerative diseases including Multiple Sclerosis (MS), Alzheimer’s disease, ALS, and Parkinsons disease.

The immune system plays a significant role in neurodegenerative diseases. In some, such as multiple sclerosis, it is the primary driver of the disease. In others, such as Alzheimer’s disease, amyotrophic lateral sclerosis, and Parkinson disease, it has an amplifying role. Immunotherapeutic approaches that target the adaptive and innate immune systems are being explored for the treatment of almost all neurological diseases, and the targets and approaches are often common across diseases. Therapeutic approaches target components of the peripheral immune system, such as regulatory T cells and monocytes, which in turn act within the CNS. Microglia are the primary immune cells in the brain that contribute to disease pathogenesis and are consequently a common immune target for therapy. The article highlights the dampening of microglia activation in MS by intranasal Foralumab.

The Review considers in detail how microglia, monocytes and T cells contribute to the pathogenesis of multiple sclerosis, Alzheimer disease, amyotrophic lateral sclerosis and Parkinson disease, and their potential as shared therapeutic targets across these diseases. The microbiome is also highlighted as an emerging therapeutic target that indirectly modulates the immune system. Therapeutic approaches being developed to target immune function in neurodegenerative diseases are discussed, highlighting how immune-based approaches developed to treat one disease could be applicable to multiple other neurological diseases.

Article Author, 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, commented, "The intranasal delivery of Foralumab represents one of the most promising approaches for the treatment of several of the most important neurodegenerative diseases including MS, Alzheimer’s disease, ALS and Parkinson’s disease. This novel approach acts by dampening microglial activation, a key driver of disease in all these neurologic conditions. Furthermore, intranasal Foralumab acts without apparent side effects and is easily administered. It is a promising therapeutic avenue for patients with neurologic diseases that have limited treatment options."

Tiziana’s CEO, Ivor Elrifi, added, "We are encouraged by the insights presented in this article, which underscore the potential of Foralumab as a groundbreaking therapy for neurodegenerative diseases. At Tiziana, we are committed to advancing innovative treatments that address significant unmet medical needs, and this publication reinforces our dedication to improving patient outcomes in progressive MS and other neurological diseases."

About Foralumab

Foralumab, a fully human anti-CD3 monoclonal antibody, is a biological drug candidate that has been shown to stimulate T regulatory cells when dosed intranasally. At present, 10 patients with Non-Active Secondary Progressive Multiple Sclerosis (na-SPMS) have been dosed in an open-label intermediate sized Expanded Access (EA) Program with either an improvement or stability of disease seen within 6 months in all patients. The FDA has recently allowed an additional 20 patients to be enrolled in this EA program. In addition, 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. The non-active SPMS intranasal foralumab Phase 2 trial (NCT06292923) began screening patients in November of 2023. Immunomodulation by nasal anti-CD3 mAb represents a novel avenue for treatment of neuroinflammatory and neurodegenerative human diseases.[1],[2]
