NEW YORK, April 13, 2023 -- Tiziana Life
Sciences Ltd. (Nasdaq: TLSA) ("Tiziana" or the "Company"), a biotechnology company developing breakthrough
immunomodulation therapies via novel routes of drug delivery, today announced it plans to investigate intranasal foralumab for the treatment
of Long COVID. The work is supported by foralumab's well-established role in de-activating microglia cells, a key component in
the pathogenesis of this disease.
anticipate entering into a Phase 2a placebo-controlled clinical trial upon successful feedback from the FDA", commented Matthew
W. Davis, M.D., RPh, Chief Medical Officer of Tiziana. "I am excited to test intranasal foralumab in this medically important condition.
The use of PET Scans will allow us to determine if intranasal foralumab will decrease activated microglia in patients with Long COVID
after 3 months of administration. After refining our clinical protocols, we need to discuss this approach with the FDA and plan to file
COVID constitutes an unmet need in society. The estimated over 9 million people in the U.S. with Long COVID will cost the healthcare
system a projected $2.6 trillion dollars.1 I believe there is substantial evidence
to support further study of intranasal foralumab in this debilitating and economically disruptive condition," commented Gabriele
Cerrone, Executive Chairman and interim Chief Executive Officer of Tiziana. "The ability to modulate pathogenic activated microglia
may have many applications in inflammatory disease states."
L. Weiner, M.D., 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, stated, "The role of activated
microglia is well-established in the pathogenesis of Long COVID.2,3,4,5,6,7,8
Our research using intranasal foralumab in patients with non-active Secondary Progressive Multiple Sclerosis (SPMS), patients
with COVID-19 and in healthy volunteers showed induction of a tolerogenic immune response by stimulating T regulatory cells while dampening
CD3+ T effector function. In essence, intranasal foralumab modulates activated microglia while returning effector T cells to a na ve
state.9 If this finding is replicated in patients with Long COVID, I believe that foralumab
could represent a novel treatment for this devasting condition."
T cells play an important role in the inflammatory process. Foralumab, the only fully human anti-CD3 monoclonal antibody (mAb), 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 demonstrated in patients with COVID and with multiple sclerosis, as well as in healthy normal subjects.
Intranasal foralumab Phase 2 trials are expected to start in the third quarter of 2023 in patients with non-active SPMS. Immunomodulation
by nasal anti-CD3 mAb represents a novel avenue for treatment of inflammatory human diseases.9
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.
Tiziana's lead candidate, intranasal foralumab, which is the only fully human anti-CD3 mAb, has demonstrated a favorable safety
profile and clinical response in patients in studies to date. Tiziana's technology for alternative routes of immunotherapy has
been patented with several applications pending and is expected to allow for broad pipeline applications.
