gen2 directed cancer immunotherapy trial

Conditions: Hepatocellular Carcinoma; Metastatic Cancer

Summary: phase 1, non-randomized, open label dose escalation clinical trial evaluating the safety of gen2 in participants with primary \& metastatic liver tumors.

this clinical trial will be divided into two phases: phase ia in which the dose, route, and schedule of the gen2 administration is determined and phase ib which is designed to explore the activity of gen2 in patients of a defined or several defined tumor types and stages based on the phase ia data of gen2. phase ia is divided into three routes of administration: (a) phase 1a.1 which explores peripheral iv infusion; (b) phase ia.2 which investigates hepatic arterial infusion and (c) phase ia.3 which examines intratumoral delivery.
