— Anaveon will present progress in EXPAND-1, a Phase I/II study of ANV600, a PD-1 targeted IL-2Rβγ agonist, in monotherapy and in combination with pembrolizumab, in advanced solid tumors  —

Basel, October 19, 2025 – Anaveon, a global clinical stage, immuno-oncology company, will present a poster on its ANV600 program at the European Society of Medical Oncology (ESMO) annual meeting being held from Friday October 17, 2025, to Tuesday, October 21, 2025, in Berlin, Germany.

ANV600 has been developed to deliver IL-2Rβγ agonism specifically to PD-1+ cells while preserving the binding site for PD-1 checkpoint inhibitors. Results of the EXPAND-1 study showed that treatment with ANV600 resulted in a dose-dependent preferential stimulation of PD1⁺ cells with higher absolute counts of CD8⁺ T cells and NK cells over regulatory T cells with good tolerability.

The abstract will be available on the ESMO website, and the accompanying poster will be on display on the ESMO 2025 meeting platform as well as on Anaveon’s website  (download poster here).
