Tiziana Reports Data Indicating Significant Immunomodulation effects on Immune and Inflammatory Biomarkers with Nasally Administered Foralumab in Healthy Volunteers.

New York/London, 26 May 2021 – Tiziana Life Sciences plc (NASDAQ: TLSA, LSE: TILS) (“Tiziana” or the “Company”), a biotechnology company focused on innovative therapeutics for inflammatory diseases and cancers, today provided an update on further analysis of lymphocyte subsets from blood samples from a Phase 1 study with nasally administered Foralumab in healthy volunteers. Results exhibiting statistically significant immunomodulatory effects on CD8 cytotoxic T-lymphocytes and other inflammatory biomarkers were observed. This Phase 1 trial, conducted at the Brigham and Women’s Hospital, Harvard Medical School, Boston, MA, was a single-site, double-blind, placebo-controlled, dose-ranging study with nasally administered Foralumab at 10, 50 and 250 mcg per day, consecutively for 5 days in healthy volunteers. The treatment was well-tolerated at all doses and there were no apparent symptoms of severe toxicity. Importantly, the treatment showed significant positive effects at 50 mcg/day dose (compared to other dose and placebo groups) on T-cell subsets and inflammatory biomarkers. These data support other clinical and pre-clinical studies showing that this route of administration is capable of inducing site-targeted immunomodulation and anti-inflammatory effects. Furthermore these pharmacodynamic data point to a clinical dose range that Tiziana intends to test in further clinical development among MS patients.
Highlights of clinical and immunologic data
• Nasally administered Foralumab was well tolerated and there were no apparent symptoms of severe toxicity or cytokine release syndrome.
• Systemic levels of Foralumab were below the lower quantitation limit of 8 ng/mL suggesting that nasally administered Foralumab appears to exert its effects via nasal epithelium utilizing local and lymphatic immune systems directly.
• Most prominent effects among cytotoxic T-cell subsets were observed in the 50mcg group compared to 10mcg, 250mcg and placebo groups.
• The observed effects in the 50mcg dose group were the following:
a. Statistically significant reductions from baseline in CD8_Tem cytotoxic T-cell subset through 14 days and CD8_TEMRA, CD8_GranzymeB, CD8_Perforin subsets through 21 days
b. Statistically significant increase from baseline in CD8_naive subset through day 21
c. Statistically significant stimulation in production of anti-inflammatory cytokine IL-10 along with suppressed production of pro-inflammatory cytokine IFN-γ, suggested a positive trend for immunomodulation and anti-inflammatory effect.
These observed clinical responses on biomarkers, indicative of immunomodulation and anti-inflammatory, are consistent with the positive clinical data observed with nasally administered Foralumab in COVID-19 patients in Brazil. Results from this clinical study demonstrated that nasally administered Foralumab at 100 mcg/day for 10 consecutive days was not only well-tolerated but it also showed significant reduction of lung inflammation along with statistically reduced levels of interleukin-6 (IL-6) and C-reactive protein (CRP), in the blood samples taken from patients (https://www.tizianalifesciences.com/news-item?s=2021-02-02-tiziana-reports-positive-data-from-the-clinical-study-of-nasal-administration-with-foralumab-its-proprietary-fully-human-anti-cd3-monoclonal-antibody-in-covid-19-patients-in-brazil).

“Nasal administration of Foralumab is a unique approach to treat patients with neurodegenerative diseases such as progressive MS , amyotrophic lateral sclerosis (ALS) and Alzheimer’s Disease (AD). This study demonstrates for the first-time that nasally administered Foralumab, at the identified optimal dose of 50 mcg/day, induces immunomodulatory effects capable of providing clinical benefit to treated subjects. These data along with results from our recently completed trial in COVID-19 patients in Brazil suggest a dose-range of 50 mcg-150mcg could be used for future clinical development of nasally administered Foralumab. This is a major accomplishment providing the scientific rationale to move forward with further clinical development of nasally administered Foralumab in patients with neurodegenerative diseases,” commented Dr. Howard L. Weiner, Chair of the Scientific Advisory Board of Tiziana Life Sciences and Professor of Neurology at Harvard Medical School. He added that “both oral and nasal administration routes are physiologic approaches to stimulate the mucosal immune system to induce disease modifying immunomodulation. Our immediate focus is on developing Foralumab for treatment of progressive MS.”
“The demonstration of the positive immunomodulatory effects providing a recommended dose-range is important to move forward with further studies in the progressive MS population”, stated Dr. Tanuja Chitnis, the study PI at the Brigham and Women’s Hospital.

About Foralumab
Foralumab (formerly NI-0401), the only entirely human anti-CD3 mAb, shows reduced release of cytokines after IV administration in patients with Crohn's disease with decreases in the classic side effects of cytokine release syndrome (CRS) and improves the overall safety profile of Foralumab. In a humanized mouse model (NOD/SCID IL2γc-/-), it was shown that while targeting the T cell receptor, orally administered Foralumab modulates immune responses of the T cells, enhances Tregs and thus provides therapeutic benefit in treating inflammatory and autoimmune diseases without the occurrence of potential adverse events usually associated with parenteral mAb therapy (Ogura M. et al., 2017). Based on animal studies, the nasal and oral administration of Foralumab offers the potential for the immunotherapy of autoimmune and inflammatory diseases in a safe manner by the induction of Tregs.
Preclinical studies on nasal and oral administration with Anti-CD3 mAbs
Preclinical and clinical studies have shown that mucosal induction of Tregs by oral or nasal administration of anti-CD3 mAbs is an innovative approach to treat autoimmune and anti-inflammatory diseases (Kuhn and Weiner 2016). Nasally administered anti-CD3 mAbs were shown to ameliorate disease in an animal model of multiple sclerosis by inducing IL-10+LAP+ (latency-associated peptide) T cells, demonstrating nasal anti-CD3 mAbs as a new approach to treat progressive forms of multiple sclerosis and other types of chronic CNS inflammation. Additionally, nasally administered anti-CD3 mAbs suppressed lupus in lupus-prone mice (BWF1) by inducing IL-10 and TGF-β dependent mechanisms associated with a suppression of IL-17 and IL-21 pro-inflammatory cytokines.
