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 Advanced Hepatocellular Carcinoma.

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/London, 5 May 2021 - 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.

ANNOUNCEMENT CONTAINS INSIDE INFORMATION FOR THE PURPOSES OF ARTICLE 7 OF REGULATION 2014/596/EU (WHICH FORMS PART OF DOMESTIC UK LAW

PURSUANT TO THE EUROPEAN UNION (WITHDRAWAL) ACT 2018 (THE "EUWA")) ("UK MAR"). UPON THE PUBLICATION

OF THIS ANNOUNCEMENT, THIS INSIDE INFORMATION (AS DEFINED IN UK MAR) IS NOW CONSIDERED TO BE IN THE PUBLIC DOMAIN.

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.
