Abstract OBJECTIVES: Doravirine, a novel NNRTI, selects for specific mutations in vitro, including mutations at reverse transcriptase (RT) positions 106, 108, 188, 227, 230 and 234. The aim of this study was to examine the prevalence of doravirine-associated resistance mutations in HIV-1-infected antiretroviral-experienced patients. METHODS: Doravirine-associated resistance mutations identified in vitro or in vivo were studied in a set of 9199 HIV-1 RT sequences from HIV-1 antiretroviral-experienced patients, including 381 NNRTI-failing patients in France and Italy between 2012 and 2017. The following mutations were considered as resistance mutations: V106A/M, V108I, Y188L, G190S, F227C/L/V, M230I/L, L234I, P236L, K103N + Y181C, K103N + P225H and K103N + L100I. RESULTS: The frequencies of doravirine-associated resistance mutations (total dataset versus NNRTI-failing patients) were: V106A/M, 0.8% versus 2.6%; V108I, 3.3% versus 9.2%; Y188L, 1.2% versus 2.6%; G190S, 0.3% versus 2.1%; F227C/L/V, 0.5% versus 1.8%; M230I/L, 2.8% versus 0%; L234I, 0.1% versus 0.5%; K103N + Y181C, 3.9% versus 3.9%; K103N + P225H, 2.9% versus 4.7%; and K103N + L100I, 1.7% versus 3.9%, with a significantly higher proportion of these mutations in the NNRTI-failing group (P < 0.05), except for M230I/L and K103N + Y181C. The overall prevalence of sequences with at least one doravirine-associated resistance mutation was 12.2% and 34.9% in the total dataset and NNRTI-failing patients (P < 0.001), respectively. In comparison, the prevalence of the common NNRTI mutations V90I, K101E/P, K103N/S, E138A/G/K/Q/R/S, Y181C/I/V and G190A/E/S/Q were higher (8.9%, 7.9%, 28.6%, 12.6%, 14.2% and 8.9%, respectively). CONCLUSIONS: These results suggest that doravirine resistance in antiretroviral-experienced patients generally and specifically among NNRTI-failing patients is lower than resistance to other NNRTIs currently used, confirming its distinguishing resistance pattern.

Note
Basic Characteristics of Mutations
  • Mutation Site: The specific location in a gene or protein sequence where a change occurs.
  • Mutation Level: The level at which a mutation occurs, including the nucleotide or amino acid level.
  • Mutation Type: The nature of the mutation, such as missense mutation, nonsense mutation, synonymous mutation, etc.
  • Gene/Protein/Region: Refers to the specific region of the virus where the mutation occurs. Including viral genes, viral proteins, or a specific viral genome region. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main
  • Gene/Protein/Region studied in the article is marked.
  • Genotype/Subtype: Refers to the viral genotype or subtype where the mutation occurs. If the article does not specifically indicate the relationship between the mutation and its correspondence, the main Genotype/Subtype studied in the article is marked.
  • Viral Reference: Refers to the standard virus strain used to compare and analyze viral sequences.
Functional Impact and Mechanisms
  • Disease: An abnormal physiological state with specific symptoms and signs caused by viral infection.
  • Immune: The article focuses on the study of mutations and immune.
