UNASSIGNED: We compared the efficacy and safety profiles of ainuovirine (ANV), a new-generation non-nucleoside reverse transcriptase inhibitor (NNRTI), with boosted elvitegravir (EVG), both coformulated with two nucleoside reverse transcriptase inhibitors (NRTIs), in people living with HIV-1 (PLWH) who had achieved virological suppression on previous NNRTI-based antiretroviral (ARV) regimen.
UNASSIGNED: This study was a multi-centre, randomised, double-blind, active-controlled, non-inferiority trial recruiting PLWH from 10 clinical centres across China. Main inclusion criteria included age of 18-65 years (inclusive), and stably staying on an ARV regimen combining an NNRTI with a two-drug NRTI backbone for at least 12 months. Eligible participants must have maintained plasma HIV-1 ribonucleic acid (RNA) titre below 50 copies per mL confirmed on two successive tests at an interval of at least one month prior to randomisation. Participants were randomly assigned to receive ANV 150 mg plus lamivudine (3TC) 300 mg, and tenofovir disoproxil fumarate (TDF) 300 mg (ANV/3TC/TDF), or cobicistat (Cobi) 150 mg boosted EVG plus emtricitabine (FTC) 200 mg, and tenofovir alafenamide (TAF) 10 mg. The primary efficacy endpoint was the proportion of participants with HIV-1 RNA titre at 50 copies per mL or above at week 48 using the US Food and Drug Administration snapshot algorithm, with a non-inferiority margin of 4 percentage points at a two-side 95% confidence level. This trial is active, but not recruiting, and is registered with Chinese Clinical Trial Registry (ChiCTR), number ChiCTR2100051605.
UNASSIGNED: Between October 2021 and February 2022, 923 patients were screened for eligibility, among whom 762 participants were randomized and had received at least one dose of ANV/3TC/TDF (n = 381) or EVG/Cobi/FTC/TAF (n = 381). At week 48, 7 (1.8%) participants on ANV/3TC/TDF and 6 (1.6%) participants on EVG/Cobi/FTC/TAF had plasma HIV-1 RNA titre at 50 copies per mL or above, including missing virological data within the time window (the Cochran-Mantel-Haenszel method, estimated treatment difference [ETD], 0.3%, 95% CI -1.6 to 2.1), establishing the non-inferiority of ANV/3TC/TDF to EVG/Cobi/FTC/TAF. The proportions of participants experiencing at least one treatment-emergent adverse events (AEs) were comparable between the two arms (97.6% versus 97.6%). A small proportion of participants discontinued study drug due to AEs (0.3% versus 0.3%). Serious AEs occurred in 11 (2.9%) participants on ANV/3TC/TDF and 9 (2.4%) participants on EVG/Cobi/FTC/TAF, respectively, none of which was considered related to study drug at the jurisdiction of the investigator. At week 48, participants on ANV/3TC/TDF showed a significantly less weight gain from baseline compared to those on EVG/Cobi/FTC/TAF (least square mean, 1.16 versus 2.05 kg, ETD -0.90 kg, 95% CI, -1.43 to -0.37). The changes in serum lipids from baseline also favoured ANV/3TC/TDF over EVG/Cobi/FTC/TAF.
UNASSIGNED: In virologically suppressed PLWH on previous NNRTI-based ARV regimen, switch to ANV/3TC/TDF resulted in less weight gain, and improved lipid metabolism while maintaining virological suppression non-inferior to that to EVG/Cobi/FTC/TAF.

In China, non-nucleoside reverse transcriptase inhibitors (NNRTIs) are integral to the antiretroviral therapy (ART) regimen for persons living with HIV (PWH), comprising over 80% of such treatments. To broaden treatment options and improve therapeutic effectiveness, Ainuovirine (ANV), a new NNRTI, was authorized for ART in 2021. Nevertheless, the clinical efficacy of ANV and its impact on blood biochemical markers remain somewhat underexplored. This study seeks to evaluate ANV\'s clinical performance in ART and its influence on relevant treatment parameters. A retrospective analysis was performed on 208 patients treated with an ANV-based regimen from July 2021 to July 2023, monitoring indicator changes from baseline to week 24. The primary endpoint was the proportion of participants achieving HIV-1 RNA levels of less than 50 copies/mL by week 24. Secondary endpoints involved assessing variations in CD4+ T cell counts and blood biochemical markers from baseline. These outcomes were also compared with data from 241 patients treated with an Efavirenz (EFV)-based regimen in the same time frame. The findings suggest that the ANV-based regimen is as effective as the EFV-based regimen in viral suppression (p > .05) and offers superior improvements in lipid profiles, liver function, and immune system indicators, alongside fewer adverse reactions. These results affirm ANV\'s efficacy and safety as an antiretroviral therapy option, offering Acquired Immune Deficiency Syndrome patients a wider array of treatment possibilities and the potential for better treatment outcomes.

This study aimed to compare the efficacy and effect on lipid profiles of Ainuovirine (ANV)- and efavirenz (EFV) -based regimens in treatment-naïve people living with HIV-1 (PLWH) at week 24. The proportion of PLWH achieving HIV-1 RNA < the limit of quantification in the ANV group was significantly higher than that in the EFV group (89.18% vs. 76.04%, P = 0.002). The mean change of log10 HIV-1 RNA from baseline was greater (-4.34 vs. -4.18, P < 0.001), the median change from baseline in CD4+ T cell count increased more (106.00 cells/μL vs. 92.00 cells/μL, P = 0.007) in the ANV group, while the CD4+/CD8+ ratio was similar (0.15 vs. 0.20, P = 0.167) between the two groups. The mean changes from baseline in total cholesterol (-0.02 for ANV vs. 0.25 mmol/L for EFV, P < 0.001), triglyceride (-0.14 for ANV vs. 0.11 mmol/L for EFV, P = 0.024), and low-density lipoprotein cholesterol (-0.07 for ANV vs. 0.15 mmol/L for EFV, P < 0.001) was significantly different between the two groups. The percentage of patients with improved lipid profiles was significantly higher in the ANV group (37.44 %) than in the EFV group (29.55%, P = 0.0495). The incidence of any adverse events in the ANV group was significantly lower than that in the EFV group at week 12 (6.2% vs. 30.7%, P < 0.001) and was comparable at week 24 (3.6% vs. 5.5%, P = 0.28). The ANV-based regimen was well tolerated and lipid-friendly in treatment-naïve PLWH.

Ainuovirine (ANV), a novel non-nucleoside reverse-transcriptase inhibitor (NNRTI), was approved in China in 2021. In a previous randomized phase 3 trial, ANV demonstrated non-inferior efficacy relative to efavirenz (EFV) and was associated with lower rates of dyslipidemia. In this study, we aimed to explore lipid changes in treatment-experienced people with human immunodeficiency virus (HIV)-1 (PWH) switching to ANV from EFV in real world. At week 24, 96.65% of patients in the ANV group and 93.25% in the EFV group had HIV-1 RNA levels below the limit of quantification (LOQ). Median changes from baseline in CD4 +T cell counts (37.0 vs 36.0 cells/µL, P = 0.886) and CD4+/CD8 +ratio (0.03 vs 0.10, P = 0.360) were similar between the two groups. The ANV group was superior to the EFV group in mean changes in total cholesterol (TC, -0.06 vs 0.26 mmol/L, P = 0.006), triglyceride (TG, -0.6 vs 0.14 mmol/L, P < 0.001), high-density lipoprotein cholesterol (HDL-C, 0.09 vs 0.08 mmol/L, P = 0.006), and low-density lipoprotein cholesterol (LDL-C, -0.18 vs 0.29 mmol/L, P < 0.001) at week 24. We also observed that a higher proportion of patients demonstrated improved TC (13.55% vs 4.45%, P = 0.015) or LDL-C (12.93% vs 6.89%, P = 0.017), and a lower proportion of patients showed worsened LDL-C (5.57% vs 13.52%, P = 0.017) with ANV than with EFV at week 24. In conclusion, we observed good efficacy and favorable changes in lipids in switching to ANV from EFV in treatment-experienced PWH in real world, indicating a promising switching option for PWH who may be more prone to metabolic or cardiovascular diseases.

UNASSIGNED: The newly approved third-generation oral anti-HIV-1 drug, ainuovirine (ANV), was used in combination with nucleoside reverse transcriptase inhibitors (NRTIs) in our study, and its effects on the lipid profile of antiretroviral-experienced HIV/AIDS patients are unclear.
UNASSIGNED: This study aimed to examine the effects of antiretroviral agents on the lipid profile in patients with HIV/AIDS.
UNASSIGNED: We conducted a real-world prospective study involving treatment-naive and treatment-experienced adult participants living with HIV-1 infection provided with ANV- or efavirenz (EFV)-based regimens. The primary endpoint was the proportion of participants with an HIV-1 RNA level of <50 copies/mL at week 24 of treatment. Secondary endpoints included the change from baseline in CD4+ T-cell count and lipid profile.
UNASSIGNED: A total of 60 treatment-naive and 47 treatment-experienced participants received an ANV-based regimen, while 88 treatment-naive and 47 treatment-experienced participants receiving an EFV-based regimen were, respectively, matched as controls. At week 24 following treatment, the proportion of participants with an HIV-1 RNA level of <50 copies/mL and the mean changes of CD4+ T-cell counts from baseline were significantly higher in naive-ANV group than those in naive-EFV group (p < 0.01). Compared with the EFV group, both naive and experienced ANV groups exhibited a favorable lipid profile, including constant changes in total cholesterol and triglycerides, a significant decrease in LDL-cholesterol (p < 0.0001), and a dramatic increase in HDL-cholesterol (p < 0.001).
UNASSIGNED: The efficacy of ANV was non-inferior to EFV when combined with two NRTIs. Patients receiving ANV-based regimens had a decreased prevalence of dyslipidemia.

BACKGROUND: Ainuovirine/lamivudine/tenofovir is a novel antiretroviral therapy regimen used to treat human immunodeficiency virus-1 (HIV-1) infection. This study aimed to compare the pharmacokinetics of ainuovirine/lamivudine/tenofovir in HIV-1-infected patients aged ≥ 65 (elderly patients) and ≤ 40 years (young patients).
METHODS: This prospective, open-label, parallel controlled clinical study included 15 young and 15 elderly patients. Blood (1 mL) was collected 30 min before dosing and at 0.5, 1, 1.5, 2, 3, 4, 8, 12, 16, and 24 h after dosing, to measure the plasma concentrations of ainuovirine/lamivudine/tenofovir. Safety was assessed by monitoring the adverse events, physical examinations, and clinical laboratory tests.
RESULTS: Plasma concentrations of each ainuovirine/lamivudine/tenofovir component reached peak levels 1-4 h after dosing and gradually decreased during the remaining observation period. Compared with the young group, ainuovirine had significantly higher T1/2Ke, AUC0-24, and AUC0-inf (all P < 0.05) in the elderly group, whereas Ke (P = 0.002) was significantly lower. However, the Cmax and Tmax of ainuovirine did not differ significantly. Lamivudine and tenofovir also had a significantly higher Cmax (p = 0.004 and p = 0.008, respectively) and AUC0-inf (P = 0.014 and P = 0.006, respectively) in the elderly group, whereas there was no significant difference in Tmax, Ke, and T1/2Ke. Ainuovirine/lamivudine/tenofovir was well tolerated in both the young and elderly groups.
CONCLUSIONS: This study suggests that the ainuovirine/lamivudine/tenofovir regimen might be an effective and safe treatment regimen for HIV-1-infected patients aged ≥ 65 years and ≤ 40 years. Further studies are needed to confirm these results and develop optimal dosing regimens for elderly HIV-1-infected patients.

UNASSIGNED: Ainuovirine (ANV) is a new non-nucleoside reverse transcriptase inhibitor (NNRTI), which was initially synthesized in Korea and later further developed in both Korea and China.
UNASSIGNED: A randomized, double-blind, double-dummy, positive parallel group, non-inferiority, phase 3 trial was conducted in 7 sites across China. Eligible HIV-1-positive antiretroviral therapy (ART)-naïve adults aged 18-65 years were randomly assigned in a 1:1 ratio to receive tenofovir disoproxil fumarate and lamivudine (TDF+3TC) in combination with either ANV (ANV group) or efavirenz (EFV group) for up to 48 weeks. Subsequently, participants in both groups received one of the two drug combinations according to their choice until week 96 in an observational study under an open-label setting. The primary endpoint was the proportion of participants achieving HIV RNA <50 copies/mL at week 48, with non-inferiority pre-specified at a margin of 10%. The secondary efficacy endpoints were logarithmic changes in HIV RNA, percentage of participants with HIV RNA levels ≤400 copies/mL and changes in the CD4 T-cell count after 48 and 96 weeks of treatment, as well as the percentage of participants with HIV RNA levels <50 copies/mL at 96 weeks of treatment. Safety endpoints were the incidence of adverse events and laboratory abnormalities evaluated according to the Division of AIDS criteria. This study was registered with the Chinese Clinical Trial Registry (Registration number: ChiCTR1800019041).
UNASSIGNED: Between November 27, 2018 and March 11, 2021, a total of 826 participants were screened, and 630 were finally enrolled and randomly assigned (1:1) to either ANV (n = 315) or EFV (n = 315) groups. The mean age was 30.6 ± 9.4 years and most participants were male (94.6%). At week 48, 274 (87.0%) of 315 participants in the ANV group and 288 (91.7%) of 314 in the EFV group achieved HIV-1 RNA <50 copies/mL and non-inferiority was established (difference: -4.7%, 95% CI: -9.6 to 0.1%). In the period, 293 participants continued to take the ANV regimen and 287 switched from the EFV to the ANV regimen. During the open-label period, 92.5% (271/293) of participants in the continued ANV group and 95.1% (273/287) in the ANV to EFV transfer group remained virologically suppressed (HIV-1 RNA <50 copies/mL) at week 96 (p = 0.189). The incidence of NNRTI treatment-related adverse events (TEAEs) at week 48 was 67.6% in 315 participants in the ANV group, which was significantly lower than in 91.4% of 314 participants in the EFV group (p < 0.001). The most common TEAEs (weeks 0-48) were dizziness (10.5%) and dyslipidemia (22.2%) in the ANV group vs. 51.0% and 34.4% in the EFV group, respectively, followed by transaminase elevation (9.2% vs. 29.0%), γ-glutamyl transferase elevation (8.3% vs. 19.1%), and rash (7.9% vs. 18.8%) (all p < 0.001). After switching from EFV to ANV, TEAEs in the former EFV participants were significantly reduced in the following observational period of 48-96 weeks.
UNASSIGNED: The week 48 results indicated that the efficacy of ANV was non-inferior to EFV when combined with two NRTIs. The per-protocol risk difference at week 48 for the primary endpoint also supported non-inferiority. TEAEs in ANV treated participants were less frequent with regard to liver toxicity, dyslipidemia, neuropsychiatric symptoms and rash compared to the EFV group during the first 48 weeks of therapy. The effects were maintained during the 48-96 weeks of therapy.
