Nous-PEV: a Novel Immunotherapy for Lung Cancer and Melanoma

Melanoma (Skin) Clinical Trial

Official title: An Open-Label, Multicenter, Non-Randomized, Dose-Confirmation and Cohort-Expansion Phase 1b Study to Evaluate the Safety, Tolerability, and Anti-Tumor Activity of Nous-PEV, With Pembrolizumab, in Patients With Unresectable Stage III / IV Cutaneous Melanoma and With Stage IV NSCLC (PDL1≥ 50%)

Status Active, not recruiting

Clinical Trial Summary

From Protocol v3.0 dated 16Jun2022. This is an international, multicenter, open-label, multiple cohort, First in Human, phase 1b clinical study, designed to evaluate safety, tolerability, and immunogenicity, and to detect any preliminary evidence of anti-tumor activity of a personalized vaccine (PEV) based on GAd-PEV priming and MVA-PEV boosting, combined with SoC first-line immunotherapy using an anti-PD-1 checkpoint inhibitor in patients with unresectable stage III/IV cutaneous melanoma or with stage IV NSCLC (PDL1 ≥ 50%). The PEV vaccines will be prepared on an individual basis, following a tumor biopsy performed at the time of screening and subsequent NGS analysis, to identify patient-specific tumor mutations. Both neoantigen-encoding genetic vaccines are administered intramuscularly using 1 prime with GAd-PEV and 3 boosts with MVA-PEV in combination with the licensed programmed death receptor-1 (PD-1)-blocking antibody pembrolizumab in adult patients in patients with unresectable stage III/IV cutaneous melanoma (Cohort a) or with stage IV NSCLC (PDL1 ≥ 50%) (Cohort b).
