Tiziana Life Sciences Overview | June 2022 18 LifeSci Venture Partners Provides active guidance and differentiated support to enhance portfolio companies’ probability of success Other Potential CNS - related Indications (Alzheimer’s and ALS) Intranasal anti - CD3 provides a unique approach for treating progressive neurologic diseases by modulating microglial cells. The intranasal route of immunotherapy has minimal toxicity and induces regulatory T cells locally, that then migrate to the brain to dampen brain inflammation.
Tiziana Life Sciences Overview | June 2022 19 Study Presented at the Alzheimer’s Association International Conference® (AAIC®) Proof - of - Concept Demonstrated in Alzheimer’s Disease In this study animal models of Alzheimer’s disease (AD) demonstrated that microglia activity was restored and cognition was improved following the dosing of intranasal anti - CD3 monoclonal antibody. • Clinical measures were assessed in the mouse models using the Y - maze and Morris water maze tests which showed improvements in cognition. Biological improvements were also observed based on restoration of genetic phenotypes as measured by the presence of homeostatic microglia genes detected by Nanostring . In addition, it was found that intranasal anti - CD3 induced the migration of regulatory T cells (Tregs) to the brain which then interacted with microglia. • Alzheimer’s is another potentially valuable application of anti - CD3 based on its ability to stimulate the immune system to promote homeostatic microglial cells while decreasing degenerative microglial cells in the brain. “Treatment of Alzheimer’s disease by modulation of microglial neuroinflammation by nasal anti - CD3 mAb ” (presented by Weiner, M.D., Co - Director of the Ann Romney Center for Neurologic Disease at the Brigham and Women’s Hospital (BWH) and Chairman of Tiziana's Scientific Advisory Board)

Tiziana Life Sciences Overview | June 2022 21 Intranasal Foralumab in Amyotrophic Lateral Sclerosis (ALS) • In September, a Lawrence & Isabel Barnett Drug Development Program Grant was awarded to the Ann Romney Center for Neurologic Diseases at Brigham and Women’s Hospital (BWH) by the ALS Association • This prestigious research grant supports the study of an intranasal anti - CD3 monoclonal antibody ( mAb ) in an animal model of Amyotrophic Lateral Sclerosis (ALS). • The grant will allow further study the role of intranasal anti - CD3 mAb in dampening the microglial activation which amplifies ALS disease progression. ALS patients have limited therapeutic options and high unmet need “We have now seen the potential of intranasal foralumab to dampen microglial activation in three major neuroinflammatory - related diseases, which creates significant optionality for exploring its benefits in some of the most important and burdensome medical conditions of our time.”
