Vienna, Austria, 18 May 2020: APEIRON Biologics AG will complete a capital increase to finance the further development of APN01 for the treatment of severely ill COVID-19 patients as well as the development of immuno-oncology projects. The Vienna Insurance Group (VIG) will lead the financing round and secures the private placement as an anchor investor, investment commitments from existing shareholders and new institutional and private international investors have been provided. In addition, the Austrian Research Promotion Agency (FFG), the Vienna Business Agency (WAW), the Austrian promotional bank (AWS) and the Erste Bank have committed grant funding and guarantees.

Peter Llewellyn-Davies, CEO of APEIRON Biologics, is pleased: "With the completion of these capital measures the financing of our clinical COVID-19 development and our immuno-oncological cell therapy projects is secured and we welcome the Vienna Insurance Group as a new investor. We also thank the FFG, the WAW, the AWS and Erste Bank for their comprehensive non-dilutive funding and guarantee commitments for our promising COVID-19 drug APN01. The joint efforts of private, industrial and governmental support help seriously ill patients who urgently need effective treatment. "

APN01 is one of the most advanced drug candidates for the treatment of COVID-19 and one of the few therapy approaches specifically targeting the coronavirus, because it imitates the receptor ACE2 and thus offers a unique dual approach to treatment. Experts believe that accelerated market approval could be completed if the study shows positive results.

Elisabeth Stadler, CEO of the Vienna Insurance Group explains: "In addition to the main objective of covering financial risks, we see ourselves as a sustainability-oriented company with a social responsibility to contribute to the well-being of society. Our investment in APEIRON Biologics not only reflects our desire to support the fight against COVID-19 and, as a consequence, other diseases as quickly as possible, but also the strategic focus to further intensify our engagement in the health care sector."

Henrietta EGERTH, Managing Director of the Austrian Research Promotion Agency (FFG), comments: "Research has a great tradition in Austria and is our most effective investment in the future. As FFG, we provide rapid funding to help accelerate ambitious, innovative projects such as the development of new treatments, so that drugs can help patients more quickly."

As part of the planned non-public capital increase, the new shares in APEIRON Biologics AG can be acquired by existing shareholders. At the end of May 2020, unsubscribed shares will be offered as a private placement to selected new private and institutional investors who have already made their investment commitments.

About APN01 and the ongoing Phase II trial:

The drug candidate APN01 (rhACE2) is a recombinant enzyme with the potential to block the infection of cells with the novel virus SARS-CoV-2 and to counteract inflammatory reactions in the lungs. With its unique dual mode of action, APN01 could become the first drug for the treatment of COVID-19, which is specifically directed against the new coronavirus SARS-CoV-2.

In the ongoing Phase II clinical trial, 200 patients severely affected by COVID-19 are to be treated. The placebo-controlled, double-blind, randomized trial was started in clinical sites in Austria, Germany, Denmark and the UK and is expected to be expanded to other countries. The primary objective of the study is to evaluate the clinical efficacy of APN01 and the safety and tolerability of APN01 in COVID-19 patients.

In previous Phase I and Phase II clinical trials, APN01 has been shown to be safe and well tolerated. The product candidate was developed by APEIRON in particular for the treatment of acute lung damage (ALI) and acute respiratory distress syndrome (ARDS). ALI / ARDS is the leading cause of death in COVID-19, the disease caused by the new coronavirus SARS-CoV-2.
