The study involves a replication-incompetent adeno-associated virus, AAV9, lacking all AAV viral genes and encoding for the human Progranulin (GRN) gene
The study involves two GMOs. ChAdOx1-HPV is a recombinant replication-incompetent chimpanzee-derived adenovirus (ChAdY25) viral vector. MVA-HPV is a modified vaccinia virus Ankara vector (MVA). Both vectors encode a fusion of sequences derived from HPV.
