PAION LAUNCHES XERAVA^(R) (ERAVACYCLINE) FOR THE TREATMENT OF COMPLICATED INTRA-ABDOMINAL INFECTIONS IN ADULTS IN THE NETHERLANDS

- Providing broad-spectrum coverage against bacterial pathogens

- XERAVA^(R) is the third product launched by PAION in Europe

Aachen (Germany), 01 September 2021 - The Specialty Pharma Company PAION AG (PA8; ISIN DE000A0B65S3; Frankfurt Stock Exchange Prime Standard) today announces that XERAVA^(R) (eravacycline) has been launched and is now commercially available in the Netherlands for order and delivery to customers through direct sales.

XERAVA^(R) is approved by the European Commission and the UK Medicines Agency for the treatment of complicated intra-abdominal infections (cIAI) in adults. Consideration should be given to official guidance on the appropriate use of antibacterial agents. XERAVA^(R) is a fluorocycline antibiotic within the tetracycline class of antibacterial drugs and provides broad-spectrum coverage against different bacterial pathogens responsible for complicated intra-abdominal infections (cIAI).

cIAI are the second most common source of severe sepsis in the ICU^[1]. Three million patients with cIAI receive a broad-spectrum antibiotic in the U.S. and EU5 (France, Germany, Italy, Spain and the UK)^[2] annually. Due to a growing concern of multi-drug resistant organisms (MDRO), especially against betalactams, including carbapenem antibiotics, PAION decided to make XERAVA^(R) available to patients as soon as possible, starting in the Netherlands, with other European markets to follow in the coming months. The initial focus of the commercial teams across Europe over the first year after launch will be to ensure that XERAVA^(R) is appropriately integrated into relevant stewardship programs and listed on hospital formularies, based on the unmet needs it can address and the health economic benefits it can deliver.

Dr. Jim Phillips, Chief Executive Officer of PAION AG, stated: "XERAVA is an important new treatment option for patients suffering from serious intra-abdominal infections. With its broad-spectrum antibacterial activity, we believe XERAVA offers an urgently needed alternative to treat life-threatening infections caused by multidrug-resistant pathogens. We are excited about our third product launch in two months to bring new treatment options to the medical community."

PAION is currently launching all of its products - Byfavo^(R), GIAPREZA^(R) and XERAVA^(R) - in a staggered manner by country so that by the end of 2022, launches are planned to have been conducted in most key European markets.

About complicated intra-abdominal infections (cIAI)
Intra-abdominal infections are common in clinical practice and comprise a wide variety of clinical presentations and differing sources of infection. According to the Infectious Diseases Society of America (IDSA), a complicated intra-abdominal infection is defined as an infection that extends beyond the wall of a hollow viscus of origin into the abdominal cavity while being associated with an abscess or peritonitis.

About XERAVA^(R) (eravacycline)
XERAVA^(R) (eravacycline) for injection is a novel fluorocycline of the tetracycline class. XERAVA^(R) is an antibiotic used to treat complicated intra-abdominal infections (cIAI) in adults.

The mechanism of action of eravacycline is to interfere with bacterial protein synthesis by binding to the ribosomal subunit 30S, thereby preventing the incorporation of amino acid residues into extended peptide chains.

XERAVA^(R) has been shown to be as effective as alternative antibiotics in two main trials in adults with cIAI. The main indicator of efficacy in both trials was the cure rate of infections. In the first trial, involving 538 patients, XERAVA^(R) was compared with the antibiotic ertapenem. After about one month, 87% of patients treated with XERAVA^(R) were cured of their infection, compared with 89% of patients treated with ertapenem. In the second trial, involving 499 patients, XERAVA^(R) was compared with meropenem (a carbapenem antibiotic commonly used in Europe in this indication). After about one month, 92% of patients treated with XERAVA^(R) and 92% of patients treated with meropenem were cured of their infection.
