Interventions
The Vigil vaccine is made up of irradiated autologous tumor cells which have been electroporated ex vivo with the Vigil plasmid designed to suppress expression of both the TGFβ1 and TGFβ2 proteins while simultaneously expressing rhGMCSF protein.
Atezolizumab was prepared and administered at the FDA approved dose and schedule as described in the U.S. Package Insert (USPI). The initial dose was administered over one hour and if well tolerated, subsequent infusions may have been administered over 30 minutes. Atezolizumab in formulation F03 (1200 mg per vial) was administered in 250 mL 0.9% NaCl IV infusion bags and infusion lines equipped with 0.2 μm in-line filters.
