"BiTAC-TCE and BiTAC-ADC development programs."
An antibody-drug conjugate (ADC) with the investigational name BITAC-ADC is a targeted cancer therapy that combines a cancer-seeking antibody with a potent drug, so the treatment behaves like a guided missile that delivers chemotherapy directly to tumor cells while sparing healthy tissue. Investors watch ADC candidates closely because their clinical trial results, safety profile and regulatory approvals can drastically affect a developer’s future revenue and stock value, but they also carry high clinical and regulatory risk.

Greater than 60% increase in laboratory space will strengthen R&D capabilities, facilitate acceleration toward clinical development, and increase ability to tap into Heidelberg’s world-class medical oncology environment

ZURICH, SWITZERLAND – June 24, 2026 -- VERAXA Biotech AG (NASDAQ: VRXA; “VERAXA”), an emerging leader in designing novel cancer therapies, today announced that the Company has moved into additional laboratory space at its existing R&D site in Heidelberg, Germany, based on a previously signed long-term lease agreement. The expansion enables the company to accommodate for currently planned team additions in its R&D department, the installation of laboratory equipment and the build-up of the final R&D infrastructure needed for planned development activities.

VERAXA is pursuing a growing portfolio of proprietary and partnered drug development programs from early, discovery stage toward early clinical development. At the heart of VERAXA’s R&D activities is the Company’s novel BiTAC strategy and its application to drive a portfolio of BiTAC-TCE and BiTAC-ADC development programs. The BiTAC therapeutic strategy is designed to unlock a new level of precision in cancer treatment by using two complementary precursors and enabling a tumor-restricted activation of the desired therapeutic effect.

“Securing the necessary space for our growing R&D organization was vital as we expand both internal drug development activities and plan ahead for an increased level of research activities within therapeutic alliances,” said Torsten Bürgermeister, Chief Financial Officer of VERAXA. “We were able to avoid any disruption of our R&D operations at our existing site in the Heidelberg biopharmaceutical cluster, which continues to provide us with a rich academic research environment and offers multiple touchpoints with some of the world’s leading research organizations in medical oncology.”
