NEW YORK and LONDON, June 23, 2021 (GLOBE NEWSWIRE) -- Tiziana Life Sciences plc (NASDAQ: TLSA, LSE: TILS), ("Tiziana" or the "Company"), a biotechnology company focused on innovative therapeutics for oncology, neurology, inflammation and infectious diseases, announces that it has signed an agreement with FHI Clinical, a global clinical contract research organization (CRO), to conduct a Phase 2 Proof-of-concept study in Brazil to evaluate the safety, tolerability and efficacy of intranasal Foralumab in hospitalized patients with severe coronavirus disease 2019 (COVID-19) and pulmonary inflammation.

A subsidiary of FHI 360, FHI Clinical specializes in the clinical development of drugs for infectious diseases (https://www.fhiclinical.com). The company’s involvement with COVID-19 includes Phase 1 to Phase 3 clinical trials for vaccines and therapeutics, as well as observational studies to collect data about the characteristics and course of infection. With experience conducting related studies across 16 countries and 43 states in the United States, FHI Clinical has a large network of clinical sites throughout the world to expedite COVID-19 trials.

In this clinical trial, Foralumab will be delivered intranasally through a metered-dose nasal atomization device. Nasal administration of Foralumab is a highly innovative approach to treat patients with autoimmune diseases where the immune system may be dysregulated. Several studies have suggested that there is dysregulation in the immune system of patients with COVID-19.

This randomized, placebo-controlled, double-blind, proof-of-concept study is designed to expand on the preliminary findings of safety, tolerability and efficacy of intranasal administration of Foralumab observed in mild to moderate non-hospitalized COVID-19 patients (https://ir.tizianalifesciences.com/news-releases/news-release-details/tiziana-life-sci-plc-positive-data-nasal-administration). Thus, this study will examine attenuation of pulmonary pathology in hospitalized patients with severe COVID-19. Up to seven sites in Brazil will be engaged to conduct this study. Eighty hospitalized patients with severe COVID-19 and evidence of pulmonary involvement on a computed tomography (CT) scan at screening will be enrolled. Patients will be randomized 1:1 to receive intranasal Foralumab 100 µg. Additionally, the study will also evaluate the effect of Foralumab on resolution of symptoms by chest CT, inflammatory biomarkers, T-cell subpopulations, safety and mucosal inflammatory response following 14 days of intranasal administration.

“Our experience is uniquely suited to the needs of this Phase 2 study as we are able to pull from past outbreak experience, including rapid study start-up in research-naïve areas to leveraging existing global research networks and contributing to local health systems,” said Ted FitzGerald, FHI Clinical President and CEO. “We excel at addressing the complex aspects of infectious disease trials that require thorough planning and contingency planning.”

“We are pleased to move forward with FHI Clinical on our next COVID-19 trial. After a successful proof-of-mechanism trial in mild to moderate COVID-19 outpatients with intranasal Foralumab earlier this year, the next step is to test it in more severe hospitalized patients with pulmonary inflammation,” said Dr. Neil Graham, Chief Medical Officer at 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 and improves the overall safety profile of Foralumab. In a humanized mouse model (NOD/SCID IL2γc-/-), it was shown that whilst 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 (NASDAQ: TLSA, LSE: TILS) is a UK biotechnology company that focuses on the discovery and development of novel molecules to treat human disease in oncology and immunology. In addition to Milciclib (a CDK inhibitor being developed in oncology), the Company is also developing Foralumab in COVID-19, multiple sclerosis, and Crohns Disease. Foralumab is the only second generation fully human anti-CD3 monoclonal antibody in clinical development in the world. This Phase 2 compound has potential application in a wide range of autoimmune and inflammatory diseases, such as nonalcoholic steatohepatitis (NASH), ulcerative colitis, multiple sclerosis, type-1 diabetes (T1D), Crohn's disease, 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 inflammatory pulmonary diseases.
