BI 1831169 is a recombinant live-attenuated Vesicular Stomatitis Virus (rVSV), modified to replace the VSV-G glycoprotein with the Lymphocytic Choriomeningitis Virus glycoprotein in order to minimize the potential of neurotoxicity for humans and skin disease in animals.
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.
