Discovery of the Novel Entecavir‐Resistant Hepatitis B Virus Reverse Transcriptase A181C Substitution From an Integrated Genotypic Analysis
Ronald E. Rose, Dennis Hernandez, Paul J. Falk, Karen Ericson, Nannan Zhou, Alexandra Thiry, Fiona McPhee – 21 August 2018 – Entecavir (ETV) is a first‐line therapy for chronic hepatitis B virus (HBV), demonstrating potent suppression of HBV DNA and a high barrier to viral resistance. Previous studies revealed that ETV‐resistant (ETVr) HBV DNA resulted from substitutions in the HBV reverse transcriptase (RT) at positions rtT184, rtS202, or rtM250 in combination with lamivudine resistance (LVDr) substitutions rtM204I/V±rtL180M.
