Tiziana Submits IND Application for Oral Formulation of Foralumab for Treatment of NASH

Tiziana Life Sciences plc (NASDAQ: TLSA; AIM: TILS), a US and UK biotechnology company that focuses on the discovery and development of novel molecules to treat human diseases in oncology and immunology, today announced that it has submitted* an Investigational New Drug application ("IND") to the U.S. Food and Drug Administration (FDA) to initiate a Phase 1 clinical trial of enteric-coated capsules of Foralumab in healthy volunteers. Foralumab, a fully human anti-CD3 monoclonal antibody (mAb), is being developed for the treatment of autoimmune and inflammatory diseases such as nonalcoholic steatohepatitis (NASH) and nonalcoholic fatty liver disease (NAFLD).

This single-site clinical study is expected to enroll 36 subjects and it will be conducted at the Brigham and Women's Hospital (BWH), Harvard Medical School. The primary objective of this study is to evaluate safety, tolerability and immunomodulatory effects of orally administered Foralumab in healthy volunteers with a dose-escalating regimen comprising of placebo, 1.25, 2.50 and 5.0 mg/day for 5 consecutive days. The trial will also investigate the established biomarkers with anti-inflammatory effects and stimulation of T regulatory cells (Tregs). Following successful completion of this study, the Company plans to launch additional clinical trials to study the potential of the oral administration of Foralumab in NASH, NAFLD and Crohn's Disease.

"Data from multiple preclinical studies1-3 has demonstrated that oral treatment with anti-CD3 mAb induces an anti-inflammatory response through induction of Tregs", commented Prof. Howard Weiner, MD. "Separately, proof-of-concept data from a Phase 2 study of OKT3, a murine anti-CD3 mAb, in NASH patients4 has established potential for orally administered therapeutics. Therefore, we believe oral immunotherapy with foralumab, a first-in-class fully human anti-CD3 mAb, has the potential to be a groundbreaking approach for targeted immunomodulation without eliciting immunosuppression throughout the body."

"Our approach, administering Foralumab orally for site-targeted clinical responses while improving efficacy and minimizing toxicity, can be a game changing treatment option for NASH and other autoimmune diseases. We are excited about the successful development of a proprietary oral formulation and submission of this IND application, which represent major milestones for advancing this groundbreaking approach forward," said Kunwar Shailubhai, Chief Executive Officer & Chief Scientific Officer of Tiziana.
