Recombinant replication-defective simian (chimpanzee-derived) group C adenovirus serotype 155 viral vector and a Modified Vaccinia Ankara virus (MVA) construct, both encoding a fusion of sequences derived from two hepatitis B virus (HBV) protein antigens
Replicative oncolytic vaccinia virus derived from the Copenhagen strain, genetically modified by inactivation of its thymidine kinase (TK) and ribonucleotide reductase (RR) genes and by addition of genes encoding for the human granulocyte-macrophage colony-stimulating factor (hGM-CSF) cytokine and for a monoclonal antibody targeting the Cytotoxic T-Lymphocyte-Antigen 4 (CTLA-4).
Recombinant replication-defective simian (chimpanzee-derived) group C adenovirus viral vector construct engineered to express three proteins from the Respiratory Syncytial Virus (RSV)
The study involves two GMOs. The GMO ChAd155-hIi-HBV is a viral suspension of a recombinant replication-defective simian (chimpanzee-derived) group C adenovirus serotype 155 (ChAd155) viral vector encoding a fusion of sequences derived from two hepatitis B virus (HBV) protein antigens. The GMO MVA-HBV is a modified vaccinia virus Ankara vector (MVA) encoding a fusion of sequences derived from two hepatitis B virus (HBV) protein antigens.
Engineered replicative oncolytic vaccinia virus (VV) derived from the Copenhagen strain. It contains three genetic modifications: 1) deletion of the viral thymidine kinase (TK) gene, 2) deletion of the viral ribonucleotide reductase (RR) gene and 3) insertion of the chimeric yeast FCU1 suicide gene in the TK locus.
