Phase 1 Study of GEN2 in Patients With Advanced Solid Tumors

Protocol GVO-1102 is a phase 1, open label, multi-center study in adult patients with locally advanced or metastatic solid tumors. This study includes two parts: dose escalation and dose expansion. In the dose escalation phase, GEN2 will be administered at increasing dose levels via intravenous infusion or intratumoral injection on Days 1, 3 and 8 every 4 weeks. Valganciclovir will start dosing on Day 12 and continue for 10 days (through Day 21). Once a recommended dose has been defined in approximately 35-45 patients, the dose expansion phase will initiate to further assess intravenous administration of GEN2 in specific tumor types. Approximately 15 patients per tumor type will be enrolled in the intravenous dose expansion phase.
