Tiziana Announces Strategic Initiative with Takanawa Japan K.K., Pharma Team, to Identify a Partner in Japan and Other Asian Countries for Further Clinical Development of Milciclib in Patients with Ad

• Objective of this partnership with Takanawa Japan K.K., Pharma Team, is to identify a strategic partner in Japan for further development of Milciclib either alone or in combination with a tyrosine kinase inhibitor (TKI) for treatment of advanced HCC patients in Asian countries where prevalence of HCC is high, and the available therapeutic options are not entirely satisfactory.
• Milciclib, a broad-spectrum cyclin dependent kinase (pan-CDK) inhibitor, has successfully completed eight phase 1 and phase 2 trials in thymic carcinoma, thymoma and hepatocellular carcinoma (HCC), showing tolerability and positive clinical responses.
• Clinical data from Phase 2a trial, presented at the American Society of Clinical Oncology 2020, indicated that orally administered Milciclib in Sorafenib-resistant patients was well-tolerated, and it produced positive clinical responses.
• Tiziana was recently awarded a patent to use Milciclib in combination with a TKI or other drugs for treatment of HCC and other cancers.

NEW YORK and LONDON, May 05, 2021 (GLOBE NEWSWIRE) -- Tiziana Life Sciences plc (Nasdaq: TLSA / LSE: TILS) ("Tiziana” or the "Company”), a biotechnology company focused on innovative therapeutics for oncology, inflammation, and infectious diseases, announces that it has executed an agreement with Takanawa Japan K.K, Pharma Team, (Takanawa) for a strategic business development plan to Identify a clinical partner in Japan and other Asian countries for further clinical development of Milciclib for treatment in advanced hepatocellular carcinoma (HCC) patients. HCC is the most common type of liver cancer and affects approximately 200,000 people per year.

Previously, Tiziana successfully completed a Phase 2 clinical trial with orally administered Milciclib in sorafenib-resistant or intolerant HCC patients. The clinical data, presented at the American Society of Clinical Oncology (ASCO)¹, demonstrated that the treatment was well-tolerated and produced clinical activity. Recently, a patent covering the use of Milciclib in combination with a tyrosine kinase inhibitor (TKI) or other drugs was granted². The granted claims provide complete freedom to further develop a combination of Milciclib with an approved TKI for treatment of patients with advanced HCC or other cancers. Because the prevalence of HCC in Asian countries is large and there are no satisfactory therapeutic options for treatment of advanced HCC in Asian countries, the strategic initiative with Takanawa is particularly important to further develop Milciclib for the treatment of advanced HCC patients.

"We are pleased and excited to work with Takanawa, a firm with a distinguished history of business development activities in the Japanese pharmaceutical industry, to identify an appropriate partner in Japan for further clinical development of Milciclib. We believe the positive clinical activity in advanced HCC and other cancers warrant immediate further development in Japan and other Asian countries where the prevalence of this cancer is relatively high, and the current available therapies are not entirely satisfactory” said Dr. Kunwar Shailubhai, CEO and CSO of Tiziana Life Sciences.

"We are honored to get the opportunity to identify a strategic partner for Milciclib for the treatment of advanced hepatocellular carcinoma (HCC) patients. Tiziana has managed to develop a product that will really have an impact and save lives since HCC affects about 200,000 people in the world and 40,000 people in Japan every year. Therefore, we hope to receive a lot of interest from leading pharmaceutical companies ” said Dr. Kaoru Nozu, Executive Representative of the Takanawa Pharma Team.
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 Milciclib

Milciclib (PHA-848125AC) is a small molecule inhibitor of several cyclin dependent kinases such as CDK1, CDK2, CDK4, CDK5 and CDK7. CDKs are serine threonine kinases that play crucial roles in progression of the cell cycle from G₁ to S phase. Overexpression of CDKs and other downstream signalling pathways that regulate cell cycles have been frequently found to be associated with development of resistance towards chemotherapies.  In a phase I study, oral treatment with Milciclib was found to be well-tolerated and the drug showed promising clinical responses in patients with advanced solid malignancies such as in NSCLC, pancreatic and colon cancer, thymic carcinoma and thymoma.

About Tiziana Life Sciences

Tiziana Life Sciences plc is a dual listed (NASDAQ: TLSA & UK LSE: TILS) biotechnology company that focuses on the discovery and development of novel molecules to treat human diseases in oncology, inflammation, and infectious diseases. In addition to Milciclib, the Company will be shortly initiating Phase 2 studies with orally administered Foralumab for Crohn’s Disease and nasally administered Foralumab for progressive multiple sclerosis. Foralumab is the only fully human anti-CD3 monoclonal antibody ("mAb”) in clinical development in the world. This Phase 2 compound has potential application in a wide range of autoimmune and inflammatory diseases, such as Crohn’s Disease, multiple sclerosis, type-1 diabetes ("T1D”), inflammatory bowel disease ("IBD”), 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 inflammation, especially for treatment of COVID-19 patients.
