The study involves two GMOs: (i) A replication-incompetent adenovirus (GAd20 with deletions of the viral E1, E3 and E4 coding regions) isolated from a gorilla and encoding the FSP neoantigens; (ii) an attenuated, replication-defective orthopoxvirus (Modified Vaccinia virus Ankara), encoding for the same neoantigens.

The nOPV2 candidate strains include different combinations of 5 distinct modified regions of the Sabin-2 genome, including changes to the RNA sequence in the 5’ untranslated region of polio genome (5’ UTR), the capsid protein coding region (P1), the non-structural protein 2C, and the polymerase 3D. Of these modifications, only the changes to polymerase 3D result in a change in the amino acid sequence. The rest of the modifications aim to stabilize the genetic sequence against reversion in either the 5’ UTR or capsid regions.
