VERAXA Biotech Provides Business Update and Further Details on Partnering Strategy and Development Timelines

ZURICH, SWITZERLAND – July 6, 2026 — VERAXA Biotech AG (NASDAQ: VRXA; “VERAXA”), an emerging leader in designing novel cancer therapies, today provided a company and pipeline update.

“In the first six months of 2026, we have made substantial progress in honing our pipeline and partnering strategy. We continue to record tangible interest in our novel BiTAC® technology and its applications in building a range of BiTAC-T cell engagers and BiTAC-antibody-drug conjugates,” stated Dr. Christoph Antz, Ph.D., Chief Executive Officer of VERAXA. “BiTAC molecules are expected to dominate our pipeline development efforts in the years to come and mature to be the main value drivers of the company. Therefore, we intend to channel the lion’s share of our investments into our BiTAC portfolio and aim to monetize selected non-BiTAC pipeline assets early to finance its growth. It is our firm goal to have a first BiTAC-TCE candidate VXA-102 IND/CTA-ready by the beginning of 2028.”

The company’s pipeline currently consists of four BiTAC-based therapeutic programs aimed at treating various solid tumor indications. Mirroring the more advanced state of development of the BiTAC-TCE platform, all of these programs are T cell engagers. Complementing our BiTAC portfolio are currently two bispecific ADCs (bs ADCs) with more traditional molecular design. This includes the bsADC program pursued within a strategic partnership with OmniAb, Inc. The formally most advanced program in VERAXA’s portfolio, the Fc-enhanced FLT3-targeting monoclonal antibody VXA-901 for the treatment of acute myeloid leukemia (AML), and the company’s HER2-targeting ADC program are available for partnering.

“Interest in novel technologies and drug development programs in the T cell engager and ADC space continues to be at a record high in the pharmaceutical industry. To benefit from this positive partnering environment, it is crucial to have a clearly differentiated technology, which we have with our BiTAC platform,“ added Heinz Schwer, Ph.D., MBA, Chief Business Officer. “The recent BIO International Partnering Conference turned out to be a well-timed opportunity for us to meet with potential new partners and also to intensify our ongoing discussions. The feedback received at this and other recent industry and scientific events gives as a great level of confidence that, with continued validation of our platform and products, we will be well positioned to secure initial partnerships.”
