BACKGROUND:

Co-formulated dolutegravir and lamivudine (DTG/3TC) is recommended as the first-line antiretroviral therapy (ART); however, the data on the viral decay in seminal plasma (SP) and blood plasma (BP), as well as changes in inflammatory biomarkers in BP, remain limited among antiretroviral-naïve people with HIV (PWH) receiving DTG/3TC. A prospective observational cohort study was conducted to compare the impact of DTG/3TC vs. bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) on viral decay kinetics and changes in inflammatory biomarkers in antiretroviral-naïve PWH.

METHODS:

Newly diagnosed PWH who initiated BIC/FTC/TAF (n=57) or DTG/3TC (n=43) were enrolled. BP and SP were collected at 0, 4, 12, 24, and 48 weeks after ART initiation. The primary endpoint was viral suppression of HIV-1 in BP and SP at week 48. Secondary endpoints included changes in HIV-1 DNA levels and inflammatory biomarkers over the 48-week follow-up.

RESULTS:

Overall, 96 (96.0%) PWH completed the 48-week follow-up (DTG/3TC, n=40; BIC/FTC/TAF, n=56). Viral suppression rates in BP and SP were comparable in the BIC/FTC/TAF and DTG/3TC groups in the per-protocol analyses at week 48 (BP, 96.4% vs. 100%, P=0.519; SP, 100% vs. 100%, P>0.999). Both regimens demonstrated similar effectiveness in reducing HIV-1 RNA levels in BP (3.0 vs. 3.1 log₁₀ copies/mL) and SP (0.9 vs. 1.2 log₁₀ copies/mL). There were no statistically significant differences in the reductions in HIV-1 DNA levels and changes in inflammatory biomarkers over the 48-week follow-up.

CONCLUSION:

These findings indicated comparable effectiveness of DTG/3TC vs. BIC/FTC/TAF in achieving viral suppression in BP and SP, and similar changes in inflammatory biomarkers in BP.

Impact of switching to injectables cabotegravir and rilpivirine on sleep disturbances in a cohort of people living with HIV

Article

Author: Sasset, Lolita ; Agostini, Elena ; Presa, Nicolò ; Gardin, Samuele ; Mazzitelli, Maria ; Leoni, Davide ; Scaglione, Vincenzo ; Cattelan, Annamaria ; Vania, Eleonora

BACKGROUND:

Recently, injectable cabotegravir/rilpivirine (ICAB/RPV) became available for HIV treatment. However, there are no real-life data on the impact of switching to ICAB/RPV on sleep disturbances (SD). Therefore, we aimed at assessing and investigating this aspect in our cohort.

METHODS:

A SD multidimensional assessment (Epworth Sleepiness scale, Insomnia severity Index, Berlin Questionnaire, and Pittsburg Sleep Quality Index, PSQI) was performed to all people who consented before starting ICAB/RPV and 12 wk after the switch. Demographics, life-style habits, laboratory, and clinical data were collected from medical health records.

RESULTS:

To June 2023, 46 people were included, 76.1% males, with a median age of 48.5 (IQR: 41-57), 50% had multimorbidity, 13% was on polypharmacy. Median age with HIV and CD4 + T cell count nadir were 10 (5-19.5) years and 360 (205-500) cell/mm³, respectively. The reason to start a long-acting strategy was person's choice in all cases. Baseline antiretroviral regimens were mostly: tenofovir alafenamide/emtricitabine/rilpivirine (39.1%) and dolutegravir/lamivudine (32.6%). No significant changes were observed in any of the scores for each questionnaire, but for a worsening PSQI. 37% people reported a subjectively improved sleep quality, even if statistically significant changes were not observed in almost all the sleep parameters.

CONCLUSIONS:

To the best of our knowledge, this is the first study exploring impact of switching to ICAB/RPV on SD. Despite integrase inhibitor have been associated with SD, we did not observed a negative impact on sleep quality after the switch to ICAB/RPV. More studies and with larger number of people are necessary to confirm our results.

Weight change with antiretroviral switch from integrase inhibitor or tenofovir alafenamide-based to Doravirine-Based regimens in people with HIV

Author: Wilson, Melissa P. ; Bandali, Mohamed Mehdi ; Kousari, Arianna E. ; Erlandson, Kristine M. ; Henao-Martínez, Andrés F. ; Hawkins, Kellie L. ; Gardner, Edward M.

BackgroundWeight gain has been well-described with integrase strand transfer inhibitors (INSTIs) and tenofovir alafenamide (TAF).Doravirine (DOR) has been identified as a relatively "weight-neutral" drug; however, there is little data describing its effect on weight change in routine clin. practice.MethodsWe conducted a retrospective chart review of weight change among people with HIV changing from an INSTI- to a non-INSTI regimen with DOR.ResultsAt the time of ART switch, among 49 people with HIV, the mean age was 47 years, 24% were female, and 75% had HIV-1 viral load <200 copies/mL.Most (55%) people with HIV were taking bictegravir/TAF/emtricitabine prior to the switch.Although 84% switched due to concerns about weight gain, only 16% had a weight gain of ≥10% in the year preceding, and 49% had no substantial change in weight 86% switched to DOR/lamivudine/tenofovir disoproxil fumarate.A weight decrease (-2.6% [95% CI: -5.1, -0.1%, p = .041] was seen over the year following the ART switch.Weight change prior to switch was greatest in the year 2021 compared to 2019, 2020, and 2022.ConclusionsOverall, modest changes in weight were seen following ART switch from INSTI-based regimen to a DOR-based, non-INSTI regimen.Further investigations with larger people with HIV cohorts will be helpful to guide clin. practice, while the impact of the COVID-19 pandemic on weight change should also be considered.

Merck Announces Topline Results from Pivotal Phase 3 Trials Evaluating Investigational, Once-Daily, Oral, Two-Drug, Single-Tablet Regimen of Doravirine/Islatravir (DOR/ISL) for the Treatment of Adults with Virologically Suppressed HIV-1 Infection

RAHWAY, N.J.--( BUSINESS WIRE )--Merck (NYSE: MRK), known as MSD outside of the United States and Canada, today announced topline results from two pivotal Phase 3 trials of the investigational, once-daily, oral, two-drug, single-tablet regimen of doravirine/islatravir [DOR/ISL (100 mg/0.25 mg)] in adults with HIV-1 infection that is virologically suppressed on different antiretroviral therapy regimens [baseline antiretroviral therapy (bART)]; MK-8591A-051 or bictegravir/emtricitabine/tenofovir alafenamide i [BIC/FTC/TAF (50 mg/200 mg/25 mg)]; MK-8591A-052 . The success criterion for the primary efficacy hypothesis, as measured by the percentage of participants with HIV-1 RNA levels ≥50 copies/mL at Week 48, was met in both trials. DOR/ISL was demonstrated to be non-inferior to bART in open-label trial MK-8591A-051 and non-inferior to BIC/FTC/TAF in double-blind trial MK-8591A-052. The superiority criteria were not met in trial MK-8591A-052. Primary safety objectives of both trials were also met. The company is planning to present detailed findings from these trials at a future scientific congress and will also plan to file these data with regulatory authorities. In the U.S., doravirine is approved for the treatment of adults with HIV-1 in combination with other antiretrovirals, as a single agent (PIFELTRO) and a component of a single-tablet regimen [DELSTRIGO; doravirine, lamivudine, and tenofovir disoproxil fumarate (DOR/3TC/TDF)]. “ We are encouraged by the results from these Phase 3 trials evaluating a once-daily, oral, two-drug, single-tablet regimen of doravirine and islatravir,” said Dr. Eliav Barr, senior vice president, head of global clinical development and chief medical officer, Merck Research Laboratories. “ We are committed to advancing our clinical programs for islatravir in combination with other antiretrovirals as potential options to help address the needs of people living with HIV.” Islatravir (MK-8591), Merck’s investigational nucleoside reverse transcriptase translocation inhibitor (NRTTI), exhibits both transcriptase and translocation inhibition (which prevents nucleotide binding and incorporation to the DNA chain, resulting in immediate chain termination) and delayed chain termination (which prevents nucleotide incorporation even in the event of translocation). Islatravir is being evaluated in multiple early and late-stage clinical trials in combination with other antiretroviral therapies for the treatment of HIV-1. In addition to the MK-8591A-051 and MK-8591A-052 trials, ongoing Phase 3 trials of DOR/ISL include MK-8591A-053 in people with HIV who had not previously received treatment (treatment-naïve), and MK-8591A-054 evaluating open-label DOR/ISL (100 mg/0.25 mg) in individuals who participated in earlier Phase 3 trials of DOR/ISL (100 mg/0.75 mg). About MK-8591A-051 ( NCT05631093 ) MK-8591A-051 is a Phase 3, randomized, active-controlled, open-label clinical trial evaluating a switch to investigational, oral, once-daily DOR/ISL (100 mg/0.25 mg) in adults with HIV-1 infection that has been virologically suppressed using ART. Participants (n=551) were randomized 2:1 to either switch to investigational DOR/ISL or continue with their current bART regimen through Week 48. After Week 48, all participants receive DOR/ISL through Week 144 of the trial. After Week 144, eligible participants may continue on DOR/ISL and continue trial treatment until Week 240 or when DOR/ISL becomes commercially accessible (whichever comes first). The primary efficacy (percentage of participants with HIV-1 RNA levels ≥50 copies/mL) and safety (number of participants experiencing adverse events (AEs) and discontinuing trial intervention due to AEs) endpoints were assessed at Week 48. About MK-8591A-052 ( NCT05630755 ) MK-8591A-052 is a Phase 3, randomized, active-controlled, double-blind clinical trial evaluating a switch to investigational, oral, once-daily DOR/ISL (100mg /0.25mg) in adults with HIV-1 infection that has been virologically suppressed using BIC/FTC/TAF (50 mg/200 mg/25 mg). Participants (n=513) were randomized 2:1 to either switch to DOR/ISL or continue on BIC/FTC/TAF through Week 144. After Week 144, eligible participants may continue on DOR/ISL and continue trial treatment until Week 240 or when DOR/ISL becomes commercially accessible (whichever comes first). The primary efficacy (percentage of participants with HIV-1 RNA levels ≥50 copies/mL) and safety (number of participants experiencing AEs and discontinuing trial intervention due to AEs) endpoints were assessed at Week 48. Indications and usage for PIFELTRO and DELSTRIGO in the U.S. PIFELTRO is indicated in combination with other antiretroviral (ARV) agents for the treatment of HIV-1 infection in adult patients with no prior ARV treatment history or to replace the current ARV regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies per mL) on a stable ARV regimen with no history of treatment failure and no known substitutions associated with resistance to doravirine. DELSTRIGO is indicated as a complete regimen for the treatment of HIV-1 infection in adult patients with no prior ARV treatment history or to replace the current ARV regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies per mL) on a stable ARV regimen with no history of treatment failure and no known substitutions associated with resistance to the individual components of DELSTRIGO. Selected Safety Information Warning: Posttreatment Acute Exacerbation of Hepatitis B (HBV) All patients with HIV-1 should be tested for the presence of HBV before initiating ARV therapy. Severe acute exacerbations of HBV have been reported in people with concomitant HIV-1 and HBV who have discontinued products containing lamivudine or tenofovir disoproxil fumarate (TDF), which are components of DELSTRIGO. Patients coinfected with HIV-1 and HBV who discontinue DELSTRIGO should be monitored with both clinical and laboratory follow-up for at least several months after stopping DELSTRIGO. If appropriate, initiation of anti-HBV therapy may be warranted. Contraindications PIFELTRO and DELSTRIGO are contraindicated when coadministered with drugs that are strong cytochrome P450 (CYP)3A enzyme inducers (including the anticonvulsants carbamazepine, oxcarbazepine, phenobarbital, and phenytoin; the androgen receptor inhibitor enzalutamide; the antimycobacterials rifampin and rifapentine; the cytotoxic agent mitotane; and the herbal product St. John’s wort (Hypericum perforatum)), as significant decreases in doravirine plasma concentrations may occur, which may decrease the effectiveness of DELSTRIGO and PIFELTRO. DELSTRIGO is contraindicated in patients with a previous hypersensitivity reaction to lamivudine. Warnings and Precautions Severe Skin Reactions Severe skin reactions, including Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN), have been reported during the postmarketing experience with doravirine-containing regimens. Discontinue PIFELTRO or DELSTRIGO, and other medications known to be associated with severe skin reactions, immediately if a painful rash with mucosal involvement or a progressive severe rash develops. Clinical status should be closely monitored, and appropriate therapy should be initiated. New or Worsening Renal Impairment Renal impairment, including cases of acute renal failure and Fanconi syndrome, have been reported with the use of TDF. DELSTRIGO should be avoided with concurrent or recent use of a nephrotoxic agent (eg, high-dose or multiple NSAIDs). Cases of acute renal failure after initiation of high-dose or multiple NSAIDs have been reported in people living with HIV with risk factors for renal dysfunction who appeared stable on TDF. Prior to or when initiating DELSTRIGO, and during treatment, assess serum creatinine, estimated creatinine clearance, urine glucose, and urine protein in all patients. In patients with chronic kidney disease, also assess serum phosphorus. Discontinue DELSTRIGO in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome. Discontinue DELSTRIGO if estimated creatinine clearance declines below 50 mL/min. Bone Loss and Mineralization Defects In clinical trials in adults living with HIV, TDF was associated with slightly greater decreases in bone mineral density (BMD) and increases in biochemical markers of bone metabolism. Serum parathyroid hormone levels and 1,25 Vitamin D levels were also higher. Cases of osteomalacia associated with proximal renal tubulopathy have been reported with the use of TDF. Immune Reconstitution Syndrome Immune reconstitution syndrome can occur, including the occurrence of autoimmune disorders with variable time to onset, which may necessitate further evaluation and treatment. Drug Interactions Because DELSTRIGO is a complete regimen, coadministration with other antiretroviral medications for the treatment of HIV-1 infection is not recommended. Coadministration of PIFELTRO with efavirenz, etravirine, or nevirapine is not recommended. If DELSTRIGO is coadministered with rifabutin, take one tablet of DELSTRIGO once daily, followed by one tablet of doravirine (PIFELTRO) approximately 12 hours after the dose of DELSTRIGO. If PIFELTRO is coadministered with rifabutin, increase PIFELTRO dosage to one tablet twice daily (approximately 12 hours apart). Consult the full Prescribing Information prior to and during treatment for more information on potential drug-drug interactions. Dosage and Administration/Specific Populations Renal Impairment Because DELSTRIGO is a fixed-dose combination tablet and the dosage of lamivudine and TDF cannot be adjusted, DELSTRIGO is not recommended in patients with estimated creatinine clearance less than 50 mL/min. Adverse Reactions The most common adverse reactions with DELSTRIGO (incidence ≥5%, all intensities) were dizziness (7%), nausea (5%), and abnormal dreams (5%). The most common adverse reactions with PIFELTRO (incidence ≥5%, all intensities) were nausea (7%), dizziness (7%), headache (6%), fatigue (6%), diarrhea (6%), abdominal pain (5%), and abnormal dreams (5%). By week 96 in DRIVE-FORWARD, 2% of adult participants in the PIFELTRO group and 3% in the darunavir+ritonavir (DRV+r) group had adverse events leading to discontinuation of study medication. By week 96 in DRIVE-AHEAD, 3% of adult participants in the DELSTRIGO group and 7% in the efavirenz (EFV)/emtricitabine (FTC)/TDF group had adverse events leading to discontinuation of study medication. In DRIVE-FORWARD, mean changes from baseline at week 48 in LDL-cholesterol (LDL-C) and non-HDL-cholesterol (non-HDL-C) were pre-specified. LDL-C: -4.6 mg/dL in the PIFELTRO group vs 9.5 mg/dL in the DRV+r group. Non-HDL-C: -5.4 mg/dL in the PIFELTRO group vs 13.7 mg/dL in the DRV+r group. The clinical benefits of these findings have not been demonstrated. In DRIVE-AHEAD, mean changes from baseline at week 48 in LDL-C and non-HDL-C were pre-specified. LDL-C: -2.1 mg/dL in the DELSTRIGO group vs 8.3 mg/dL in the EFV/FTC/TDF group. Non-HDL-C: -4.1 mg/dL in the DELSTRIGO group vs 12.7 mg/dL in the EFV/FTC/TDF group. The clinical benefits of these findings have not been demonstrated. In DRIVE-SHIFT, mean changes from baseline at week 24 in LDL-C and non-HDL-C were pre-specified. LDL-C: -16.3 mg/dL in the DELSTRIGO group vs -2.6 mg/dL in the PI + ritonavir group. Non-HDL-C: -24.8 mg/dL in the DELSTRIGO group vs -2.1 mg/dL in the PI + ritonavir group. The clinical benefits of these findings have not been demonstrated. In DRIVE-AHEAD, neuropsychiatric adverse events were reported in the three pre-specified categories of sleep disorders and disturbances, dizziness, and altered sensorium. Twelve percent of adult participants in the DELSTRIGO group and 26% in the EFV/FTC/TDF group reported neuropsychiatric adverse events of sleep disorders and disturbances; 9% in the DELSTRIGO group and 37% in the EFV/FTC/TDF group reported dizziness; and 4% in the DELSTRIGO group and 8% in the EFV/FTC/TDF group reported altered sensorium. The safety of DELSTRIGO in virologically-suppressed adults was based on week 48 data from participants in the DRIVE-SHIFT trial. Overall, the safety profile in virologically-suppressed adult participants was similar to that in participants with no ARV treatment history. Serum ALT and AST Elevations: In the DRIVE-SHIFT trial, 22% and 16% of participants in the immediate switch group experienced ALT and AST elevations greater than 1.25 X ULN, respectively, through 48 weeks on DELSTRIGO. For these ALT and AST elevations, no apparent patterns with regard to time to onset relative to switch were observed. One percent of participants had ALT or AST elevations greater than 5 X ULN through 48 weeks on DELSTRIGO. The ALT and AST elevations were generally asymptomatic, and not associated with bilirubin elevations. In comparison, 4% and 4% of participants in the delayed switch group experienced ALT and AST elevations of greater than 1.25 X ULN through 24 weeks on their baseline regimen. Pregnancy/Breastfeeding There is a pregnancy exposure registry that monitors pregnancy outcomes in individuals exposed to PIFELTRO or DELSTRIGO during pregnancy. Healthcare providers are encouraged to register patients by calling the Antiretroviral Pregnancy Registry (APR) at 1-800-258-4263. Inform individuals with HIV-1 infection of the potential risks of breastfeeding, including: (1) HIV-1 transmission (in HIV-1–negative infants), (2) developing viral resistance (in HIV-1–positive infants), and (3) serious adverse reactions in a breastfed infant similar to those seen in adults. About Islatravir (MK-8591) and Merck’s HIV Research Islatravir (MK-8591) is Merck’s investigational nucleoside reverse transcriptase translocation inhibitor (NRTTI) under evaluation in multiple ongoing early and late-stage clinical studies in combination with other antiretrovirals for the treatment of HIV-1.

ViiV Healthcare Announces Data Demonstrating Dovato (DTG/3TC) Is Highly Effective in Treatment-Naïve People With Advanced HIV

LONDON--( BUSINESS WIRE )--ViiV Healthcare, the global specialist HIV company majority owned by GSK, with Pfizer and Shionogi as shareholders, today announced 48-week findings from the DOLCE study, sponsored by Fundación Huésped and the Bahiana Foundation of Infectiology, showing the 2-drug regimen Dovato (dolutegravir/lamivudine [DTG/3TC]) achieved similar results to 3-drug therapy in viral suppression in a population of adults with advanced HIV. A post-hoc analysis of the study showed DTG/3TC was non-inferior to 3-drug therapy regardless of the participant’s baseline viral load. These data were presented at HIV Glasgow 2024 , being held in Glasgow, Scotland from 10 – 13 November. Harmony P. Garges, M.D., Chief Medical Officer, at ViiV Healthcare, said: “We know taking fewer medicines is an important consideration for many in the HIV community, and these new data continue to reinforce the efficacy and safety of Dovato, a 2-drug regimen. The findings from the DOLCE study build on the robust body of evidence supporting its use in treatment-naïve adults living with HIV and shows comparable efficacy to a 3-drug regimen, even in people with low CD4 counts and high viral loads.” DOLCE is a randomised, open-label, multicentre study assessing the efficacy and safety of DTG/3TC in 230 antiretroviral treatment (ART)-naïve people with advanced HIV (low CD4 counts [≤200 cells/mL]). 1 In the clinical trial, participants were randomised in a 2:1 ratio to receive DTG/3TC (n=152) or DTG+TDF/XTC (n=77). The baseline characteristics of the participants were similar between the two treatment groups and represented a population of people with severe immunosuppression – 43% of participants having baseline CD4 counts less than 100 cells/mL, 69% having baseline viral load (VL) greater than 100,000 copies (c)/mL, and 23% having a very high baseline VL, greater than 500,000 copies (c)/mL. The primary endpoint of the study was the proportion of subjects with VL <50 copies/ml at week 48. At week 48 comparable efficacy was observed, with 82% of individuals in the DTG/3TC group and 80% in the 3-drug regimen group achieving a VL<50. Furthermore, a post-hoc analysis showed that Dovato was non-inferior to the 3-drug regimen in achieving a VL<50. Prof. Pedro Cahn, Scientific Director of Fundación Huésped study investigator of the DOLCE study, said : “It’s encouraging to see additional new data that continue to support the efficacy and safety of 2-drug regimens compared to traditional 3-drug regimens. The results from DOLCE provide healthcare providers with further confidence in prescribing DTG/3TC and are important findings for people living with HIV taking medicines to suppress their virus.” A post-hoc analysis reported that DTG/3TC was non-inferior to 3-drug therapy (adjusted risk difference of 2.0%, 95% CI -8.6; 12.8%). 1 The study also showed that secondary efficacy measures of viral load decline, time to viral suppression, and CD4 recovery were similar between arms. Efficacy by baseline viral load categories was similar across both arms, including those with baseline viral load greater than 500,000 copies with 74% in the DTG/3TC arm, and 67% in the DTG+TDF/XTC arm achieving virologic success. The change in median CD4 count from baseline to Week 48 showed an increase of 200 cells/mL in the DTG/3TC arm and an increase of 177 cells/mL in the triple therapy arm. Safety through Week 48 was comparable across both arms and consistent with known safety profiles and showed similar rates of serious adverse events (SAEs) and immune reconstitution inflammatory syndrome across arms. The rate of discontinuation in both arms was also similar (DTG/3TC = 12.8%; DTG+TDF/XTC = 6.8%). About DOLCE The DOLCE (NCT04880395) randomised clinical trial is a phase IV, open-label, multicentre clinical trial assessing the efficacy of DTG/3TC for the treatment of HIV-1 in treatment-naïve adults 18 years or older with CD4+ T-cell count ≤200 c/mm3 and HIV-1 RNA >1,000 copies/mL with no known ART-resistance or HBV co-infection, conducted in 11 sites across Argentina and Brazil. The primary endpoint was the proportion of participants with plasma HIV-1 RNA <50 c/mL at Week 48 (FDA snapshot for ITT-E population) and secondary outcomes included, among others, efficacy, resistance, safety, and tolerability.

ViiV Healthcare expands on real-world data supporting use of long-acting therapies in diverse patient populations at HIV Glasgow

LONDON--( BUSINESS WIRE )--ViiV Healthcare, the global specialist HIV company majority owned by GSK, with Pfizer and Shionogi as shareholders, will share new data from its industry-leading HIV treatment and prevention portfolio and pipeline at HIV Glasgow 2024, being held in Glasgow, Scotland from 10 – 13 November 2024. Spanning 42 abstracts, the data showcases long-acting and two-drug regimens as care options for diverse populations in the face of a continuing HIV epidemic. Harmony P. Garges, MD, Senior Vice President and Chief Medical Officer at ViiV Healthcare, said: “ViiV Healthcare is the first company to develop and launch long-acting options and two-drug regimens, and these therapies are transforming how physicians and providers treat and prevent HIV today. We continue evaluating how diverse populations living with or impacted by HIV respond to our therapies in the real world. Data from these studies include more than 10,000 people using Vocabria + Rekambys , more than 50,000 people using Dovato and more than 1,300 people using Apretude 1 . At HIV Glasgow, ViiV Healthcare is showcasing new, compelling data from our portfolio that reinforces how our medicines impact health outcomes and contribute to ending the HIV epidemic. ” Key data to be presented at HIV Glasgow 2024 by ViiV Healthcare and its study partners will include: Analysis of cabotegravir + rilpivirine long-acting (CAB+RPV LA) in the real-world and across phase 3/3b studies : Findings from a large-scale post hoc analysis of the complete long-acting HIV treatment regimen CAB+RPV LA will be presented. The analysis, which pooled data from over 2,500 participants across four major phase 3/3b clinical trials (FLAIR, ATLAS, ATLAS-2M, and SOLAR), will compare virologic outcomes and isolated viraemic events between daily oral HIV treatment and CAB+RPV LA. 2 Furthermore, the real-world utilisation of CAB+RPV LA will be explored in an analysis of adherence and persistence in a Canadian patient support program. These analyses will add to the growing body of clinical and real-world evidence for CAB+RPV LA and offer additional insights to healthcare providers on outcomes for CAB+RPV LA in diverse populations. Data exploring the use of dolutegravir/lamivudine (DTG/3TC) in antiretroviral-naïve people living with HIV: Findings will be presented from the Fundación Huésped-sponsored DOLCE study. This is the first study to fully focus on evaluating the efficacy and safety of the 2-drug regimen DTG/3TC in people living with HIV with CD4 ≤ 200 cells/mm³. 3 Additionally, data will be shared from the phase IV D2ARLING study, which compared the efficacy and safety of DTG/3TC against a 3-drug regimen in an antiretroviral-naïve population that did not have baseline drug-resistance testing results available. 4 Many guidelines recommend baseline drug resistance testing prior to antiretroviral therapy (ART) initiation, that may not always be readily accessible, reinforcing the need and impact of these data in an antiretroviral-naïve population. Cost-effectiveness and usage patterns for long-acting HIV prevention: Findings from a cost-effectiveness study examining the economic and public-health impact of cabotegravir long-acting (CAB LA) for HIV pre-exposure prophylaxis (PrEP) in Canada will be presented. Researchers will compare the impact of the introduction of CAB LA for PrEP against daily oral PrEP (TDF/FTC) and no PrEP usage on cost savings and quality-adjusted life years. 5 New findings from the PROTECT survey will be shared, exploring differences in interest and intention to use long-acting PrEP among men who have sex with men and heterosexual men and women in 20 European countries. 6,7 Advancing novel mechanisms of action in HIV research: New findings from the BANNER study of VH3810109 (N6LS), an investigational, broadly neutralising antibody (bNAb), will be presented. Previously presented phase IIa proof-of-concept findings from the BANNER study suggested VH109 was well-tolerated and efficacious in people living with HIV. 8 Researchers will share new findings exploring the correlation between baseline phenotypic sensitivity to N6LS and virologic response after treatment with N6LS. 9 Additional research evaluating N6LS will focus on administration and dose responsiveness, adding to the growing body of evidence supporting the bNAb as a potential new approach to treating HIV. 10 ViiV Healthcare-sponsored or supported studies to be presented at HIV Glasgow 2024: Title First Author Presentation Cabotegravir + rilpivirine long-acting Similar virologic outcomes and frequency of isolated viraemic events (blips, low-level viraemia and suspected virologic failure) between oral and long-acting antiretroviral therapy: a pooled analysis of phase 3/3b cabotegravir + rilpivirine long-acting studies J.
