Ultimovacs ASA's Phase II FOCUS trial results, published on medRxiv, showed no clinical benefits in PFS or OS when adding UV1 to pembrolizumab in late-stage HNSCC patients, missing primary and secondary endpoints. UV1 maintained a positive safety profile. The trial, led by Prof. Mascha Binder and sponsored by the University of Halle-Wittenberg, aimed to assess UV1's efficacy and tolerability as an add-on to pembrolizumab. Patients were randomized 2:1 to receive UV1+pembrolizumab or pembrolizumab alone, with primary endpoint PFS at 6 months. UV1, a universal cancer vaccine targeting telomerase, is administered via intradermal injections with GM-CSF over three months.
