Tiziana Life Sciences #TILS – Develops Novel Investigational Treatment For Patients Infected with COVID-19

New York/London — April 9,  2020 – Tiziana Life Sciences plc (Nasdaq: TLSA) (“Tiziana” or the “Company”), a biotechnology company focused on innovative therapeutics for inflammatory and autoimmune diseases, announced today that it has developed investigational new technology to  treat COVID-19 infections, which consists of direct delivery of anti-IL-6 receptor (anti-IL-6R) monoclonal antibodies (mAbs) into the lungs using a handheld inhaler or nebulizer. Development of this novel technology is a step forward toward expediting  development of  TZLS-501, a fully-human anti-interleukin-6 receptor (anti-IL6R) monoclonal antibody (mAb) for treatment of patients infected with COVID-19 (SARS-CoV-2) coronavirus.  The Company believes the technology could also be applicable for use with other FDA approved mAbs and drugs.  The Company has submitted a provisional patent application for the delivery technology.

“Direct delivery of anti-IL-6R mAb to the lungs using a portable handheld inhaler or nebulizer is a rapid and immediate therapy for children and adults infected with COVID-19.  Importantly, this treatment with our fully human anti-IL-6R mAb (TZLS-501) has the potential to be a long-term therapy to halt progression and reduce mortality in patients with COVID-19, as a portion of the population may not opt to utilize a vaccine,” said Gabriele Cerrone, Chairman of Tiziana Lifesciences.  

Patients infected with COVID-19 are known to develop an uncontrolled immune response (“cytokine storm”), which results in excessisive production of pro-inflammatory cytokines and other proteins such as interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-a) and Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF), which in turn causes severe damage to lung tissue resulting in respiratory failure and eventually  death. Among these cytokines, IL-6 seems to be one of the major culprits underlying coronavirus-mediated respiratory failure. Early clinical studies conducted by doctors in China suggest that anti-IL6R mAbs may be used in clinical practice for treatment of COVID-19.  Consequently, China’s National Health Commission has  recommended the use of Roche’s blockbuster drug, Actemra® and Sanofi’s Kevzera® for treatment of patients infected with COVID-19.  

Excessive production of IL-6 is regarded as a key driver of chronic inflammation and is believed to be associated with the severe lung damage commonly observed with COVID-19 infections and acute respiratory distress syndrome (ARDS).  Tiziana believes TZLS-501 (anti-IL6R) combined with this newly introduced inhalation technology may rapidly inhibit inflammation in lungs and in combination with intravenous administration may deplete circulating levels of IL-6 and potentially halt progression of COVID-19-mediated lung damage and death.

“The filing of this comprehensive provisional patent application covering treatment with our anti-IL-6R mAb, as well as prophylactic intervention with a vaccine candidate, designed from Spike (S) protein of COVID-19, is an important step in finding a solution to the current pandemic. We look forward to providing updates on the development of this product candidate and its introduction into clinical trials in a real-world setting,” said Dr. Kunwar Shailubhai, CEO & CSO of Tiziana Life Sciences.

About TZLS-501

TZLS-501, a fully human mAb, was acquired from Novimmune, a Swiss biotechnology company, in 2017. The cytokine, IL-6, a major determinant in the priming of pathogenic T cells to produce an inflammatory response, binds to its receptor subunit IL-6Rα on the cell membrane. The receptor IL-6Rα can be shed as a soluble sIL6Rα, which binds to circulating IL-6 cytokine in the blood. The downstream signaling from which sIL-6R is implicated mediates pro-inflammatory effect underlying the inflammatory diseases such as rheumatoid arthritis (RA) and acute respiratory distress syndrome (ARDS). The Company believes that the novel features of TZLS-501 consisting of its dual mechanism of action to inhibit signaling by the membrane-bound and soluble IL-6 receptor and the rapid depletion of circulating IL-6 cytokines, which is the major cause of lung damage, provides this mAb with distinct advantages for treatment of COVD-19.  The Company licensed TZLS-501 from Novimmune, a Swiss biotechnology company, in 2017.

The person who arranged for the release of this information was Dr Kunwar Shailubhai, the Chief Executive Officer of the Company.

About Tiziana Life Sciences

Tiziana Life Sciences plc 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, the Company is also developing Foralumab for liver diseases. Foralumab is the only 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.

Tiziana Life Sciences (Nasdaq: TLSA; AIM: TILS) – TZLS-501 Potential Treatment of Certain Patients Infected with Coronavirus COVID-19

New York/London, March 11,  2020 – Tiziana Life Sciences plc (Nasdaq: TLSA; AIM: TILS) (“Tiziana” or the “Company”), a biotechnology company focused on innovative therapeutics for inflammatory and autoimmune diseases, announced today that it is expediting  development of  TZLS-501, a novel, fully human anti-interleukin-6 receptor (anti-IL6R) monoclonal antibody (mAb) for treatment of patients infected with coronavirus COVID-19 (SARS-CoV-2). Tiziana plans to administer TZLS-501 using a proprietary formulation technology. The Company entered into a world-wide license for composition-of-matter of TZLS-501, a fully human mAb targeting IL-6R, with Novimmune, SA, a Swiss biotechnology company in 2017.

Certain patients infected with coronavirus COVID-19 may develop an uncontrolled immune response (“cytokine storm”) resulting in severe damage to lung tissue which could lead to respiratory failure (see Note 1, below). Early clinical studies conducted by doctors in China suggest that anti-IL6R mAbs may be used in clinical practice for treatment of COVID-19.  Consequently, China’s National Health Commission has recommended the use of Roche’s blockbuster drug, Actemra® for treatment of patients infected with COVID-19, with serious lung damage and elevated IL-6 levels. Actemra was first approved by the FDA in 2010 for rheumatoid arthritis. Besides Actemra®, Sanofi and Regeneron are currently exploring Kevzara®, an FDA-approved anti-IL-6 receptor therapy for rheumatoid arthritis, for treatment of severe COVID-19. 

Tiziana’s anti-IL-6R mAb  binds to both the membrane-bound and soluble forms of IL-6R and rapidly depletes circulating levels of IL-6 in the blood (see Note 2, below).  An excessive production of IL-6 is regarded as a key driver of chronic inflammation and is believed to be associated with severe lung damage observed with COVID-19 infections and acute respiratory illness. A recent Chinese study also reported that COVID-19 infection caused clusters of severe respiratory illness such as severe acute respiratory distress syndrome (ARDS) (see Note 3, below).

“We believe that the features of TZLS-501 consisting of its dual mechanism of action to inhibit signaling by the membrane-bound and soluble IL-6 receptors along with rapid depletion of circulating IL-6 cytokine, a major cause of lung damage, provides TZLS-501 with distinct advantages for treatment of COVID-19 over other anti-IL-6R mAbs such as Actemra® and Kevzara® for treatment of COVID-19.  The recent decision by researchers in China to add Actemra® to treatment guidelines for coronavirus patients with serious lung damage confirms the utility of anti-IL6R mAb.  We are excited to move forward with our clinical development plan to expedite evaluation in patients as soon as possible”, said Dr. Kunwar Shailubhai, CEO & CSO of Tiziana Life Sciences.
