Purpose

Ref: Protocol v7.0, dated 23Mar2022. NOUS-209-01 is a multicenter, open-label, multiple cohorts, clinical study, designed to evaluate safety, tolerability, and immunogenicity, and to detect any preliminary evidence of anti-tumor activity of Nous-209 genetic polyvalent vaccine plus pembrolizumab combination therapy in adult subjects with unresectable or metastatic deficient mismatch repair (dMMR) or MSI-H CRC, gastric, or gastro-esophageal junction (G-E junction) tumors. Nous-209 is based on a heterologous prime/boost regimen composed of the Great Ape Adenovirus GAd20-209-FSP used for priming and Modified Vaccinia virus Ankara MVA-209-FSP used for boosting. The Phase I portion of the study is a first-in-human (FIH) clinical study with a primary objective to elucidate the safety and tolerability of Nous-209 in addition to establishing the recommended Phase 2 dose (RP2D), whereas the Phase II was introduced to assess efficacy as the primary objective.
