Tiziana Announces Submission of a Patent Application for Nasal Administration of Foralumab, A Fully Human Anti-CD3 Monoclonal Antibody, for Treatment of COVID-19 Patients

New York/London, July 31, 2020 - Tiziana Life Sciences plc (Nasdaq: TLSA / AIM: TILS) ("Tiziana" or the "Company"), a biotechnology company focused on innovative therapeutics for oncology, inflammation and infectious diseases, is pleased to announce that it has submitted a patent application for the potential use of nasally administered Foralumab, a fully human anti-CD3 monoclonal antibody (mAb), for the treatment of COVID-19 either alone or in combination with other anti-viral drugs. Recent clinical studies imply that a combination of anti-inflammatory and anti-viral drugs may be more effective to treat patients at different stages of COVID-19 disease.

·      Nasal administration with Foralumab could potentially modulate or stimulate immune system to suppress cytokine storm and reduce respiratory failure in
COVID-19 patients

·      Nasal administration of Foralumab may be combined with other anti-viral drugs to improve treatment efficacy

Tiziana has a worldwide exclusive license for nasal administration of Foralumab and other anti-CD3 mAbs for the treatment of neurodegenerative and other diseases. The Company previously announced development of a robust formulation and delivery of Foralumab using a nasal spray device and the successful completion of a Phase 1 trial demonstrating that the treatment was well-tolerated and showed positive immunomodulatory effects as measured by biomarker analysis (https://www.tizianalifesciences.com/news-item?s=2018-11-28-tiziana-announces-initiation-of-phase-1-clinical-trial-with-nasal-administration-of-foralumab-a-fully-human-anti-cluster-definition-3-monoclonal-antibody-anti-cd3-mab-in-healthy-volunteers).

Additionally, Tiziana also reported the successful completion of a Phase 1 trial with oral administration of Foralumab, demonstrating that the treatment was well-tolerated up to a 5 mg dose (https://www.tizianalifesciences.com/news-item?s=2020-01-09-tiziana-reports-phase-1-clinical-data-demonstrating-oral-treatment-with-foralumab-a-fully-human-anti-cd3-monoclonal-antibody-is-well-tolerated-in-healthy-volunteers). Importantly, both clinical studies conducted at the Brigham and Women's Hospital and Harvard Medical School, Boston, MA., indicated that the severe toxicities that are commonly associated with intravenous administration of anti-CD3 mAbs were not observed with either oral or nasal administration of Foralumab.

"Nasal administration of Foralumab is a potentially transformative immunomodulatory approach for treating patients with a variety of human diseases. Results from animal studies, conducted in our laboratory have established that nasal administration of anti-CD3 induces regulatory T cells that suppress inflammation and ameliorate diseases in animal models. This scientific advancement provides the basis to move forward with clinical development of nasally administered Foralumab in COVID-19 disease," commented Dr. Weiner, who is the Robert L. Kroc Professor of Neurology at the Harvard Medical School, Director and Founder of the Partners Multiple Sclerosis Center and Co-Director of the Ann Romney Center for Neurologic Diseases at the Brigham & Women's Hospital. He continued, "modulating the immune system with nasal anti-CD3 is a first-in-class immunotherapeutic approach to treat COVID-19 disease."

"Our proprietary immunotherapeutic approach using nasal, inhalation and oral administration of mAbs are novel and promising therapies that stimulate or modulate the immune system so that T regulatory cells (Tregs) are supercharged to inhibit inflammation. The common underlying concept in these alternative delivery approaches is to strengthen one's own body defense to fight against inflammation in these diseases. Being a fully human anti-CD3 mAb, we believe Foralumab is most suitable for immunotherapies, as it does not produce an immune response unlike other humanized anti-CD3 mAbs" commented Dr. Shailubhai, CEO and CSO of Tiziana Life Sciences.

The person who arranged for the release of this announcement on behalf of the Company was Dr Kunwar Shailubhai, Chief Executive Officer and Chief Scientific Officer of the Company.

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 regulatory T-cells (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.

 

About Tiziana Life Sciences

Tiziana Life Sciences plc is a dual listed (NASDAQ: TLSA & UK AIMS: TILS) biotechnology company that focuses on the discovery and development of novel molecules to treat human diseases in oncology, inflammation and infectious diseases. In addition to milciclib, the Company will be shortly initiating phase 2 studies with orally administered Foralumab for Crohn's Disease and nasally administered Foralumab for progressive multiple sclerosis. Foralumab is the only fully human anti-CD3 monoclonal antibody (mAb) in clinical development in the world. This phase II compound has potential application in a wide range of autoimmune and inflammatory diseases, such as Crohn's Disease, multiple sclerosis, type-1 diabetes (T1D), inflammatory bowel disease (IBD), psoriasis and rheumatoid arthritis, where modulation of a T-cell response is desirable. The company is accelerating development of anti-Interleukin 6 receptor (IL6R) mAb, a fully human monoclonal antibody for treatment of IL6-induced inflammation, especially for treatment of COVID-19 patients.
