We investigated the mutation profiles of severe acute respiratory syndrome coronavirus 2 in samples collected from a molnupiravir and nirmatrelvir/ritonavir combination therapy in macaques. We found that molnupiravir induced several nirmatrelvir resistance mutations at low abundance that were not further selected in combination therapy. Coadministration of nirmatrelvir/ritonavir lowered the magnitude of the mutagenetic effect of molnupiravir.
Keywords: SARS-CoV-2; combination therapy; lethal mutagenesis; molnupiravir; nirmatrelvir.
