Mont-Saint-Guibert, Belgium, 30th June 2021 – Promethera Therapeutics SA, a pioneer in cell therapies for severe liver diseases, today announces a financing agreement for an amount of € 20M. This fundraising will allow the progress of the clinical development of HepaStem®, aimed to serve as alternative to liver transplant thanks to stem cell therapy restoring liver health. Belgian, German and Chinese investors contribute to this new fundraising. Through its affiliate Shang Ying International Holdings Limited, the Chinese company Tata Health International Holding Co., Ltd., a company listed on the Hong Kong Stock Exchange will invest an amount of € 10M in the Walloon company. At the same time, a license agreement will allow the clinical development of Hepastem® in China.

This fundraising is intended to conduct Hepastem®'s Phase IIB clinical trial in the continuity of Phase IIA which has demonstrated safety and preliminary signs of efficacy in ACLF. It aims to demonstrate the effectiveness of Hepastem® in improving liver function and survival of ACLF patients.

Acute-on-chronic liver failure (ACLF) is an acute complication of chronic liver disease caused by toxic, viral or immune injuries of the liver. ACLF affects more than 50000 patients in the EU and USA every year and is associated to a very high short-term mortality of 40% to 70% depending on the stages of severity. In ACLF, the liver failure is complicated by that of one or more organs such as the heart, the lungs, the brain. ACLF reaches 30% of patients hospitalized for acute decompensation of liver cirrhosis. Strong systemic inflammation is one of the features in the pathophysiology of this syndrome and there is no treatment. At present, liver transplantation remains the only clearly identified option for ACLF, but the presence of uncontrolled comorbidities or infections, the shortage of organs to be transplanted, as well as other patient characteristics limit the eligibility of patients with ACLF for liver transplantation.

HepaStem® aims at bringing a therapeutic alternative. Liver stem cells are administered to the patient intravenously and are transported through the blood into the liver, in the intent to reduce the severe systemic and liver inflammation, and thereby, restoring liver health.

"We welcome our new investors and thank them for their trust. This new phase of our clinical development offers a great opportunity for growth for the company but also a therapeutic innovation for the hepatological community, that of participating in the development of a drug of a new kind, and which we hope will bring patients a real benefit in this lethal disease, without current therapeutic solution" declared Prof Etienne Sokal, historical Founder and Chairman of the Board of Promethera.

"Wallonia is once more demonstrating its solid biotechnology expertise and its attractiveness for investors in the field, as a recognition of the long-standing efforts to revamp the industrial landscape in high technology and life science sector" said Minister Willy Borsu, Vice President of Wallonia and Minister of Economy, Research & Innovation.

Mr. Yang Jun, Chairman of the Board of Directors of TATA Health International Holdings, said: "We are delighted and looking forward to the cooperation with Promethera® Therapeutics. We hope that with the technical expertise of Promethera® Therapeutics in liver cell therapy and the layout and resources of our group in domestic medical and big health industries, we can bring gospel to patients with liver diseases in China and Asia, and maximum value for shareholders."

"With this new fundraising, Promethera® accelerates its development after having recently recentered its activities on key and most promising indications. This roundtable is an important token of our investor’s trust in our renewed strategy, focusing on our key assets", says Etienne Sokal.

About HepaStem®

HepaStem® is an advanced therapy medicinal product intended to bring an alternative to transplantation. HepaStem® is a drug manufactured from healthy human liver tissue and produced on a large scale under GMP (Good Manufacturing Practice) conditions. HepaStem® is administered by simple peripheral intravenous infusion and is transported through the bloodstream to the inflamed liver. Preclinical and clinical results suggest that HepaStem® may reduce inflammation and fibrosis through its ability to perform paracrine regenerative and immunomodulatory functions on CD4+ T cells and liver cells. These combined effects are expected to play a favorable role in the restoration of liver homeostasis. HepaStem® is currently being tested in ACLF (clinical Phase IIB). Additional liver diseases’ treatments are also under development pre-clinical stage.
