“In the third quarter of 2023, BioInvent achieved a significant landmark with the recruitment of the first patient to the BI-1808 single agent Phase 2a study. BI-1808 can potentially become a novel checkpoint inhibitor and thus play an important role in the context of immune oncology. BioInvent is leading the field of companies aiming to unlock the value of TNFR2 in cancer therapy.” - Martin Welschof, CEO of BioInvent.
