Experimental: FusionVAC-XS15 and Atecolizumab treatment |
Drug: Fusion-VAC-XS15
FusionVAC-22 peptide will be administered subcutaneously (s.c.) adjuvanted with the Toll-like receptor 1/2 ligand XS15 (50 μg) emulsified in Montanide ISA 51 VG (1:1). Vaccination will take place every 4 weeks at the beginning of Cycle 1 and 2. A total of two vaccinations are planned. After 11 months a booster vaccination can be applied depending on T-cell responses. Immune checkpoint inhibition (ICI): Atezolizumab (TecentriqTM, Roche Pharma AG) is a humanized immunoglobulin (Ig) G1 monoclonal antibody that targets PD-L1 and will be applied intravenously (i.v.). The anti-PD-L1 antibody Atezolizumab (TecentriqTM) 1680 mg will be applied every 4 weeks as a 30-minute infusion (60-minute first dose) starting on day 15 after the first vaccination. Anti-PD-L1 treatment will be continued after the end of vaccination phase throughout the complete study period until End of Treatment (EOT) or until disease progression or other reasons for study termination. |
- To assess immunogenicity in terms of induction of peptide specific T-cell responses [ Time Frame: through study completion, an average of 1 year ]The percentage of patients with an induction of T-cell response until 28 days after second vaccination will be the primary endpoint for efficacy. Peptide stimulated Peripheral Blood Mononuclear Cells (PBMCs) are analyzed by enzyme-linked immunospot (ELISPOT).
- Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability] of the peptide vaccine in combination with anti-PD-L1 immune checkpoint inhibition [ Time Frame: through study completion, an average of 1 year ]The safety and toxicity of the personalized multi-peptide vaccine in combination with the toll-like receptor1/2 ligand XS15 with anti-PD-L1 immune checkpoint inhibition (ICI) will be determined based on the Common Terminology Criteria for Adverse Events (CTCAE version 5.0) and assessed in a descriptive manner.
