Remdesivir-induced emergence of SARS-CoV2 variants in patients with prolonged infection.

ABSTRACT: We here investigate the impact of antiviral treatments such as remdesivir on intra-host genomic diversity and emergence of SARS-CoV2 variants in patients with a prolonged course of infection. Sequencing and variant analysis performed in 112 longitudinal respiratory samples from 14 SARS-CoV2-infected patients with severe disease progression show that major frequency variants do not generally arise during prolonged infection. However, remdesivir treatment can increase intra-host genomic diversity and result in the emergence of novel major variant species harboring fixed mutations. This is particularly evident in a patient with B cell depletion who rapidly developed mutations in the RNA-dependent RNA polymerase gene following remdesivir treatment. Remdesivir treatment-associated emergence of
