Fusion-VAC-XS15

Two doses of the DNAJB1-PRKACA fusion-based neoepitope vaccine Fusion-VAC-XS15 will be applied subcutaneously (s.c.) with a 4-week interval in combination with the anti-programmed cell death-ligand 1 (PD-L1) antibody atezolizumab starting at day 15 after the first vaccination. Clinical trial results will be published in peer-reviewed journals. EU CT Number: 2022-502869-17-01 and ClinicalTrials.gov Registry (NCT05937295).

Based on these encouraging results, we established a Phase I open-label, multicentric clinical trial to evaluate the immunogenicity along with safety and toxicity, as well as first signs of efficacy of the FusionVAC-22 based peptide vaccine, combined with the immune checkpoint inhibitor (ICI) atezolizumab, in 20 patients with locally advanced or metastatic FL-HCC or other malignant diseases that carry the DNAJB1-PRKACA fusion transcript. Furthermore, disease control rate, quality of life as well as overall and progression free survival will be assessed. Clinical trial information: NCT05937295.

Most importantly, until now the second patient showed stable disease for 8 months after vaccination. Based on these promising data, we established a Phase I open label, multicentric clinical trial (EU-CT Number 2022-502869-17-00) evaluating the immunogenicity along with safety and toxicity, as well as first signs of efficacy of the FusionVAC-22 based peptide vaccine, combined with an ICI (anti-PD-L1), in 20 patients with locally advanced or metastatic FL-HCC or other malignant disease with proven presence of the DNAJB1-PRKACA fusion transcript.
