Tiziana Life Sci PLC - Submission of Patent Application
("Tiziana" or the "Company")
Tiziana Announces Submission of Patent Application on Use of Foralumab, the Only Fully Human Anti-CD3 Monoclonal Antibody, to Enhance Success of CAR-T Therapy
· Foralumab treatment could potentially enhance expansion and survival of chimeric antigen receptor T cells (CAR-T) therapy for cancers and other human diseases
· Foralumab may be co-administered either alone or in combination with other drugs to improve success of CAR-T therapy
"The CAR-T is one of the most promising therapies utilizing T cells from your own immune system, which are genetically engineered and supercharged to hunt down and destroy cancer cells. In this context, we are developing oral and nasal administrations of Foralumab for the treatment of Crohn's Disease and progressive multiple sclerosis, respectively. The common underlying approaches in these programs are to strengthen your own body defenses to fight against these diseases. Being a fully human anti-CD3 mAb, Foralumab is most suitable for CAR-T therapy as it does not produce an immune response unlike other humanized anti-CD3 mAbs" commented
Typically, CAR-T cell therapies are created using a patients' own T cells that have been engineered to express a chimeric antigen receptor (CAR) to reprogram the T cells to kill cancer cells. The CAR combines the specificity of a mAb with the cytotoxic and memory functions of T cells. CAR-T cell therapy has shown tremendous promise in the treatment of a variety of hematological and solid cancers, and potentially for patients with autoimmune diseases. Despite encouraging clinical success, relapse rates following CAR-T therapy are high, limiting the utility of this promising cancer therapy. An improved CAR-T therapy can be achieved through more efficient production processes by optimizing the ex vivo expansion conditions and/or providing concomitant therapies utilizing anti-CD3 mAbs, either alone or in combination with other co-stimulatory molecules such as an anti-IL-6 receptor mAbs, an anti-CD28 mAbs or specific inhibitors of signaling pathways of phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT), or mammalian target of rapamycin (mTOR).
This announcement contains inside information for the purposes of Article 7 of the Market Abuse Regulation (EU) 596/2014 ("MAR"), encompassing information relating to the Placing as described above, and is disclosed in accordance with the Company's obligations under Article 17 of MAR.

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.
