- Tiziana is Developing the First Oral Form of Foralumab in a Convenient Capsule to be Evaluated in Phase 1b Clinical Study

NEW YORK, Feb. 04, 2022 (GLOBE NEWSWIRE) -- Tiziana Life Sciences Ltd (Nasdaq: TLSA) (“Tiziana” or the “Company”), a biotechnology company enabling breakthrough immunotherapies via novel routes of drug delivery, today announced submission of an amendment to an Investigational New Drug (IND) application for evaluation of orally administered capsules of foralumab, which it believes would be the first “take home” immunotherapy, in patients with mild-to-moderately active Crohn’s Disease. If accepted by the U.S. Food and Drug Administration (FDA), the amendment is expected to expedite patient enrollment and completion of the foralumab Phase 1b study by the fourth quarter of 2022.

The currently planned Phase 1b study with an amended protocol is designed as a placebo-controlled, randomized and dose-escalating trial, in mild-to-moderate patients with Crohn’s Disease. The patients will be dosed up to 5 mg once daily for five consecutive days and safety of patients will be monitored throughout the treatment period in the hospital or clinical research unit (CRU). The primary objective of this study is to determine safety and tolerability. The study will also evaluate the pharmacodynamic (PD) effects on modulation of immunobiomarkers, including calprotectin, a widely used biomarker for gut inflammation, in stools, as a secondary endpoint. Data from an earlier Phase 1a, single-ascending dose (SAD) study with orally administered foralumab in healthy volunteers determined that the treatment was well-tolerated up to 5 mg, which was the highest dose tested.

This amendment would allow for the investigation of a broader patient population as well as a shorter dosing period. Previously, Tiziana had submitted an IND to conduct a Phase 1b study in moderate-to-severe active Crohn’s Disease patients to evaluate safety of enteric-coated foralumab capsules administered orally once daily for 14 days as an inpatient study in the hospital or CRU with safety monitoring, for which the FDA issued a ‘Study May Proceed letter’. However, initial feasibility findings indicated that enrollment of patients in this initial safety study, requiring 14-day hospitalization, was highly challenging due to the COVID-19 pandemic. Thus, the clinical protocol has been amended to expedite patient enrollment and study completion.

The clinical findings from this Phase 1b study could support moving foralumab into a Phase 2 clinical trial in patients with mild-to-moderate Crohn’s Disease. Tiziana is awaiting FDA’s comments on the amended TILS-014 protocol and, with clearance of the amendment, anticipates completing the Phase 1b study by the fourth quarter of 2022.

Dr. Kunwar Shailubhai, Chief Executive Officer of Tiziana noted, “Current immunotherapies for treatment of Crohn’s disease, including ulcerative colitis, are administered either intravenously or subcutaneously. In this clinical study, foralumab would be formulated as a novel, convenient, ‘take home’ immunotherapy in an oral capsule form. Thus, submission of this IND amendment marks an important step towards advancing our novel approach as well as validating the local mode of action of foralumab to potentially treat Crohn’s Disease and other inflammatory bowel diseases”.

About Foralumab
Foralumab (formerly NI-0401), the only entirely human anti-CD3 mAb, shows reduced release of cytokines after IV administration in healthy volunteers and in patients with Crohn's disease. 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 and 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. Clin Immunol.183:240-246). Once a day treatment for 10 consecutive days with intranasal foralumab was not only well tolerated but it also produced strong clinical responses in COVID-19 patients (Moreira et al., 2021. Front Immunol. 2021; 12: 709861). Based on these studies, the intranasal and oral administration of Foralumab offers the potential to become a well-tolerated immunotherapy for autoimmune and inflammatory diseases by the induction of Tregs.

About Tiziana Life Sciences Ltd
Tiziana Life Sciences is a clinical-stage biopharmaceutical company developing breakthrough therapies using transformational drug delivery technologies to enable alternative routes of immunotherapy. Tiziana’s innovative nasal, oral and inhalation approaches in development have the potential to provide an improvement in efficacy as well as safety and tolerability compared to intravenous (IV) delivery. Tiziana’s two lead candidates, intranasal foralumab, the only fully human anti-CD3 mAb, and milciclib, a pan-CDK inhibitor, have both demonstrated a favorable safety profile and clinical response in patients in studies to date. Tiziana’s technology for alternative routes of immunotherapy has been patented with several applications pending and is expected to allow for broad pipeline applications.
