Zurich, 29th of December 2023: VERAXA Biotech AG, a pioneering company in the development of superior antibody-based cancer therapies and a portfolio company of Xlife Sciences AG (SIX: XLS), is proud to announce the acquisition of Synimmune GmbH and its innovative Phase I antibody (FLYSYN) for the treatment of Acute Myeloid Leukemia (AML). This marks a major milestone in the company's history and with the expansion of VERAXA’s cancer pipeline it is hope for patients battling AML - one of the most common types of acute leukemia in adults.

The FLYSYN antibody was acquired by VERAXA Biotech AG from Xlife Sciences AG portfolio company Synimmune GmbH via a share deal. The deal included an upfront payment as well as several milestones and will reach a total deal value of up to 32 million EUR. With this clinical asset, VERAXA strengthens its internal cancer pipeline of innovative antibodies and antibody-drug conjugates (ADCs).

AML, characterized by its prevalence in individuals over the age of 68 and accounting for approximately 1% of all cancer occurrences, has long presented a challenge in the medical community, particularly for those under 45 where it is less common. The successful First-in-Man multicenter clinical study of FLYSYN focused on patients with AML who had measurable residual disease (MRD). The introduction of FLYSYN, is a testament to VERAXA Biotech AG's commitment to advancing healthcare and providing innovative solutions for serious health conditions.

Oliver R. Baumann, CEO of Xlife Sciences AG comments: «Securing the innovative Phase I antibody, FLYSYN, for Acute Myeloid Leukemia (AML) treatment marks a significant step forward. This milestone reflects our commitment to advancing healthcare and sets the stage for a promising future in reshaping AML treatment. »

Dr. Christoph Antz, CEO of VERAXA Biotech AG, stated: «With FLYSYN, we are one step closer to offering better, more effective treatments for those affected by Acute Myeloid Leukemia. »
