Abstract OBJECTIVES: Low HIV reservoirs may be associated with viral suppression under a lower number of antiretroviral drugs. We investigated tenofovir disoproxil fumarate/emtricitabine as a maintenance strategy in people living with HIV (PLHIV) with low HIV-DNA. METHODS: TRULIGHT (NCT02302547) was a multicentre, open-label, randomized trial comparing a simplification to tenofovir disoproxil fumarate/emtricitabine versus a triple regimen continuation (tenofovir disoproxil fumarate/emtricitabine with a third agent, control arm) in virologically suppressed adults with HIV-DNA <2.7 log10 copies/106 PBMCs and no prior virological failure (VF). The primary endpoint (non-inferiority margin 12%) was the percentage of participants with a plasma viral load (pVL) <50 copies/mL in ITT (Snapshot approach) and PP analyses at Week 48 (W48). RESULTS: Of the 326 participants screened, 223 (68%) were randomized to the tenofovir disoproxil fumarate/emtricitabine arm (n = 113) or control arm (n = 110). At W48, the tenofovir disoproxil fumarate/emtricitabine and control arms maintained a pVL < 50 copies/mL in 100/113 (88.5%) and 100/110 (90.9%) participants, respectively (ITT difference 2.4%, 95% CI -5.9 to 10.7; PP difference 3.4%, 95% CI -4.2 to 11.0). Six VFs occurred in the tenofovir disoproxil fumarate/emtricitabine arm (two with emerging mutations M184V and K65R) versus two in the control arm (ITT difference 3.5%, 95% CI -1.9 to 9.4). All VFs were resuppressed after treatment modification. CONCLUSIONS: Although non-inferiority was shown, simplification to tenofovir disoproxil fumarate/emtricitabine should not be used for most PLHIV because of a low risk of VF with resistance.

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.
