AI Summary
Xencor announced that XmAb819 Phase 1 results in ENPP3+ ccRCC were accepted for an ESMO 2026 proffered paper, with expansion cohorts guiding the Phase 3 dose. A pivotal monotherapy trial for advanced ccRCC is planned to start in 2027, while IV and subcutaneous dosing expansion and IO-combination sub-studies open in 2026, potentially expanding XmAb819’s addressable tumors and setting up a late-2020s catalyst.
