Veraxa Biotech AG Announces Regulatory Progress with Its BiTAC -TCE Development Plan Veraxa Biotech AG announced that it has received Scientific Advice from the German regulatory authority, the Paul-Ehrlich-Institute (PEI), regarding the underlying biology and proposed non-clinical development plan for its most-advanced development program based on its proprietary BiTAC-TCE technology. In the PEI's Scientific Advice procedure, drug developers can consult with regulatory experts on how to best evaluate their new drug candidates with a key focus on safety and tolerability. The advice was given in a meeting in which Veraxa Biotech AG presented the scientific rationale for the BiTAC-TCE mechanism together with its proposed safety assessments and pharmacokinetics strategy. The supportive feedback indicates that the authorities understand the biological concept behind the dual-targeting, conditionally active BiTAC-TCE format, which provides an initial derisking of the development path and greater clarity as the company advances its BiTAC-TCE program. Initial data from Veraxa Biotech AG's most advanced BiTAC-TCE program were presented at the American Association for Cancer Research (AACR) Annual Meeting 2026, in April. In those studies, Veraxa Biotech AG's BiTAC-TCE candidate performed as intended in vitro and in vivo, attacking cancer cells displaying both target molecules while sparing cells expressing only one of the two targets. The data demonstrated a superior safety profile with matching efficacy compared with a more traditional TCE, pointing to the possibility of a meaningfully improved therapeutic index.
