Abstract BACKGROUND: Multi-tablet regimens (MTRs) are associated with increased adverse events and non-adherence. Single tablet regimens (STRs) plus boosted protease inhibitors (PIs) are a simplification option for MTR-treated patients; however, data is needed to validate this therapeutic strategy. METHODS: This retrospective analysis included all HIV-1 infected patients seen at a single center from March 2016 to December 2017 who were switched from twice-daily (BID) regimens or regimens containing >/= 3 pills daily to elvitegravir/cobicistat/emtricitabine/tenofovir-alafenamide (E/C/F/TAF) plus darunavir (DRV) or rilpivirine/emtricitabine/tenofovir-alafenamide (RPV/F/TAF) plus DRV boosted with ritonavir or cobicistat (DRV/r-c). Eligible patients had baseline HIV-1 RNA<200 copies/mL and were followed for 48 weeks. The primary endpoint was HIV-1 RNA>/=50 copies/mL at Week 48. Adherence and safety data were recorded throughout the study. RESULTS: Of 61 patients included, median age was 53 years, the median number of pills taken daily (range) was 5 (3-9), 80% were taking BID regimens, 97% had baseline HIV-1 RNA<50 copies/mL, 56 (92%) were switched to E/C/F/TAF plus DRV and 5 (8%) to RPV/F/TAF plus DRV/r-c. At Week 48, 2 patients (3%) had HIV-1 RNA>/= 50 copies/mL, both were treated with E/C/F/TAF plus DRV and neither had evidence of treatment-emergent resistance. Fifty-nine (97%) had an HIV-1 RNA<50 copies/mL. Adverse drug reactions (ADRs) occurred in 3/61 (5%) (all Grade 2) leading to 3/61 (5%) ADR-related discontinuations. CONCLUSION: In this real-world cohort of MTR-treated patients, switching to a TAF-based STR plus boosted PI maintained virologic control in 97% and was well-tolerated, supporting potential use of this strategy for regimen simplification.

Mutation Information
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.
  • Target Gene: Host genes that viral mutations may affect.
Clinical and Epidemiological Correlations
  • Clinical Information: The study is a clinical or epidemiological study and provides basic information about the population.
  • Treatment: The study mentioned a certain treatment method, such as drug resistance caused by mutations. If the study does not specifically indicate the relationship between mutations and their correspondence treatment, the main treatment studied in the article is marked.
  • Location: The source of the research data.
