Study of VB10.NEO in Combination With Atezolizumab in Solid Tumors

A Phase 1B, Open-Label, Dose-Escalation Study of the Safety of and Antigen-specific Immune Responses Elicited by VB10.NEO in Combination With Atezolizumab in Patients With Locally Advanced and Metastatic Tumors

A phase 1b, open-label, multicenter, dose-escalation study designed to evaluate the safety, tolerability, antigen-specific immune response and preliminary antitumor activity associated with VB10.NEO administered in combination with atezolizumab, and to identify a RP2D for VB10.NEO in combination with atezolizumab, in patients with locally advanced and metastatic tumors that have progressed after at least 1 available standard therapy; or for whom standard therapy has proven to be ineffective or intolerable, or is considered inappropriate; or for whom a clinical trial of an investigational agent is a recognized standard of care (SOC).
