ViiV HEALTHCARE TO PRESENT PHASE IIIB DATA COMPARING DOVATO WITH BIKTARVY IN TREATMENT-NAÏVE ADULTS; ALONGSIDE INSTI-POWERED LONG-ACTING INJECTABLE INNOVATION AT AIDS 2026

  • VOGUE is the first head-to-head, randomised daily orals study comparing 2-drug regimen Dovato with 3-drug regimen Biktarvy in treatment-naïve adults living with HIV
  • Real-world OPERA data continues to strengthen the evidence base for Cabenuva, the only complete long-acting injectable HIV treatment regimen
  • Six-month results from the CLARITY study will report participant experience and acceptability of long-acting cabotegravir versus lenacapavir injections after a single dose in HIV-negative adults

London, 21 July 2026 ViiV Healthcare, the global specialist HIV company majority owned by GSK, with Shionogi as a shareholder, today announced new clinical and real-world data highlighting its integrase strand transfer inhibitor (INSTI)-focused portfolio, including long-acting (LA) medicines and pipeline momentum, to be presented at the 26th International AIDS Conference (AIDS 2026) in Rio de Janeiro, Brazil, from 26-31 July.

VOGUE daily orals phase IIIb data will compare ViiV Healthcare’s established 2-drug regimen dolutegravir/lamivudine (DTG/3TC) with 3-drug regimen bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) in treatment-naïve adults living with HIV1

  • Additional data from VOGUE will examine the study population demographics, including adults with high viral loads.2
  • A pooled analysis across clinical trials will examine on-study viraemic events and outcomes for DTG/3TC compared with 3-drug regimens.3

Data evaluating long-acting injectable HIV treatment, including late-breaking LATA results and OPERA real-world data, will add to the evidence base for cabotegravir + rilpivirine long acting (CAB+RPV LA)

  • Late-breaking week 96 results from the LATA study, led by University College London, will evaluate the efficacy, safety and acceptability of CAB+RPV LA versus daily oral tenofovir disoproxil fumarate/lamivudine/dolutegravir in virologically suppressed adolescents living with HIV across sub-Saharan Africa.4
  • New data from OPERA will be presented, including from the US-based cohort, comparing the virologic effectiveness of injectable CAB+RPV LA versus daily oral BIC/FTC/TAF in virologically suppressed adults living with HIV.5,6,7
  • Week 96 results from the IMPALA study, led by London School of Hygiene and Tropical Medicine, will provide new insights into the use of CAB+RPV LA in adults living with HIV with prior adherence challenges in sub-Saharan Africa, including treatment outcomes over time.8
  • Data from Ask Us Europe, a community co-produced survey, led by an academic team in London, will explore whether people living with HIV across Europe are having meaningful and equitable conversations with healthcare providers about long-acting HIV treatment options.9,10,11

CAB LA for pre-exposure prophylaxis (PrEP) data, including CLARITY results comparing CAB LA with lenacapavir, will inform how long-acting injectable prevention options are used in practice

  • Six-month results from the phase I CLARITY study will report participant experience and acceptability of CAB LA versus lenacapavir injections after a single dose, as well as late-breaking data on participant-reported outcomes, informing decision-making when initiating long-acting injectables for PrEP.12,13
  • CAPTIVATE results will describe real-world use, acceptability and delivery of CAB LA for PrEP in routine US clinical practice.14,15
  • Updated PrEPFACTS results will describe real-world use and adherence patterns for CAB LA for PrEP in the US, using healthcare administrative claims data.16

EXTEND 4M will evaluate a new long-acting dosing candidate for HIV prevention

  • Baseline data from the phase IIb registrational EXTEND 4M trial will describe the population being evaluated in the first study evaluating a new formulation of CAB LA dosed three times a year for HIV PrEP.17 This study builds on the established evidence for CAB LA for PrEP dosed six times a year and will assess the pharmacokinetics, safety and tolerability of the new CAB LA formulation.

APRETUDE (cabotegravir) extended-release injectable suspension
Professional Indication and Important Safety Information

INDICATION

APRETUDE is indicated for pre-exposure prophylaxis (PrEP) to reduce the risk of sexually acquired HIV-1 infection in adults and adolescents weighing at least 35 kg who are at risk for HIV-1 acquisition. Individuals must have a negative HIV-1 test prior to initiating APRETUDE (with or without an oral lead-in with oral cabotegravir) for HIV-1 PrEP.

IMPORTANT SAFETY INFORMATION
BOXED WARNING: RISK OF DRUG RESISTANCE WITH USE OF APRETUDE FOR HIV-1 PRE-EXPOSURE PROPHYLAXIS (PrEP) IN UNDIAGNOSED HIV-1 INFECTION

Individuals must be tested for HIV-1 infection prior to initiating APRETUDE or oral cabotegravir, and with each subsequent injection of APRETUDE, using a test approved or cleared by the FDA for the diagnosis of acute or primary HIV-1 infection. Drug-resistant HIV-1 variants have been identified with use of APRETUDE by individuals with undiagnosed HIV-1 infection. Do not initiate APRETUDE for HIV-1 PrEP unless negative infection status is confirmed. Individuals who acquire HIV-1 while receiving APRETUDE for PrEP must transition to a complete HIV-1 treatment regimen.

CONTRAINDICATIONS

  • Do not use APRETUDE in individuals:
    • with unknown or positive HIV-1 status
    • with previous hypersensitivity reaction to cabotegravir
    • receiving carbamazepine, oxcarbazepine, phenobarbital, phenytoin, rifampin, and rifapentine

WARNINGS AND PRECAUTIONS
Comprehensive Management to Reduce the Risk of HIV-1 Infection:

  • Use APRETUDE as part of a comprehensive prevention strategy, including adherence to the administration schedule and safer sex practices, including condoms, to reduce the risk of sexually transmitted infections (STIs). APRETUDE is not always effective in preventing HIV-1 acquisition. Risk for HIV-1 acquisition includes, but is not limited to, condomless sex, past or current STIs, self-identified HIV risk, having sexual partners of unknown HIV-1 viremic status, or sexual activity in a high prevalence area or network. Inform, counsel, and support individuals on the use of other prevention measures (e.g., consistent and correct condom use; knowledge of partner[s] HIV-1 status, including viral suppression status; regular testing for STIs)
  • Use APRETUDE only in individuals confirmed to be HIV-1 negative. HIV-1 resistance substitutions may emerge in individuals with undiagnosed HIV-1 infection who are taking only APRETUDE, because APRETUDE alone does not constitute a complete regimen for HIV-1 treatment. Prior to initiating APRETUDE, ask seronegative individuals about recent (in past month) potential exposure events and evaluate for current or recent signs or symptoms consistent with acute HIV-1 infection (e.g., fever, fatigue, myalgia, skin rash). If recent (<1 month) exposures to HIV-1 are suspected or clinical symptoms consistent with acute HIV-1 infection are present, use a test approved or cleared by the FDA as an aid in the diagnosis of acute HIV-1 infection
  • When using APRETUDE, HIV-1 testing should be repeated prior to each injection and upon diagnosis of any other STIs
  • Additional HIV testing to determine HIV status is needed if an HIV-1 test indicates possible HIV-1 infection or if symptoms consistent with acute HIV-1 infection develop following an exposure event. If HIV-1 infection is confirmed, then transition the individual to a complete HIV-1 treatment
  • Counsel individuals without HIV-1 to strictly adhere to the recommended dosing and testing schedule for APRETUDE 

Potential Risk of Resistance with APRETUDE:

  • There is a potential risk of developing resistance to APRETUDE if an individual acquires HIV-1 either before, while taking, or following discontinuation of APRETUDE. To minimize this risk, it is essential to clinically reassess individuals for risk of HIV-1 acquisition and to test before each injection to confirm HIV-1–negative status. Individuals who are confirmed to have HIV-1 infection must transition to a complete HIV-1 treatment. If individuals at continuing risk of HIV-1 acquisition discontinue APRETUDE, alternative forms of PrEP should be considered and initiated within 2 months of the final injection of APRETUDE

Long-Acting Properties and Potential Associated Risks with APRETUDE:

  • Residual concentrations of cabotegravir may remain in the systemic circulation of individuals for prolonged periods (up to 12 months or longer). Take the prolonged-release characteristics of cabotegravir into consideration and carefully select individuals who agree to the required every-2-month injection dosing schedule because non-adherence or missed doses could lead to HIV-1 acquisition and development of resistance 

Hypersensitivity Reactions:

  • Serious or severe hypersensitivity reactions have been reported in association with other integrase inhibitors and could occur with APRETUDE
  • Discontinue APRETUDE immediately if signs or symptoms of hypersensitivity reactions develop. Clinical status, including liver transaminases, should be monitored and appropriate therapy initiated 

Hepatotoxicity:

  • Hepatotoxicity has been reported in a limited number of individuals receiving cabotegravir with or without known pre-existing hepatic disease or identifiable risk factors
  • Clinical and laboratory monitoring should be considered and APRETUDE should be discontinued if hepatotoxicity is suspected and individuals managed as clinically indicated

Depressive Disorders:

  • Depressive disorders (including depression, depressed mood, major depression, persistent depressive disorder, suicidal ideation or attempt) have been reported with APRETUDE
  • Promptly evaluate patients with depressive symptoms

Risk of Reduced Drug Concentration of APRETUDE Due to Drug Interactions:

  • The concomitant use of APRETUDE and other drugs may result in reduced drug concentration of APRETUDE
  • Refer to the full Prescribing Information for steps to prevent or manage these possible and known significant drug interactions, including dosing recommendations. Consider the potential for drug interactions prior to and during use of, and after discontinuation of APRETUDE; review concomitant medications during use of APRETUDE

ADVERSE REACTIONS

The most common adverse reactions (incidence ≥1%, all grades) with APRETUDE were injection site reactions, diarrhea, headache, pyrexia, fatigue, sleep disorders, nausea, dizziness, flatulence, abdominal pain, vomiting, myalgia, rash, decreased appetite, somnolence, back pain, and upper respiratory tract infection.

DRUG INTERACTIONS

  • Refer to the full Prescribing Information for important drug interactions with APRETUDE
  • Drugs that induce UGT1A1 may significantly decrease the plasma concentrations of cabotegravir

USE IN SPECIFIC POPULATIONS

  • Lactation: Assess the benefit-risk of using APRETUDE to the infant while breastfeeding due to the potential for adverse reactions and residual concentrations in the systemic circulation for up to 12 months or longer after discontinuation
  • Pediatrics: Not recommended in individuals weighing less than 35 kg

CABENUVA (cabotegravir; rilpivirine) extended-release injectable suspensions
Professional Indication and Important Safety Information

INDICATION

CABENUVA is indicated as a complete regimen for the treatment of HIV-1 infection in adults and adolescents 12 years of age and older and weighing at least 35 kg to replace the current antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA <50 copies/mL) on a stable antiretroviral regimen with no history of treatment failure and with no known or suspected resistance to either cabotegravir or rilpivirine.

IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS

  • Do not use CABENUVA in patients with previous hypersensitivity reaction to cabotegravir or rilpivirine
  • Do not use CABENUVA in patients receiving carbamazepine, oxcarbazepine, phenobarbital, phenytoin, rifabutin, rifampin, rifapentine, systemic dexamethasone (>1 dose), and St John’s wort

WARNINGS AND PRECAUTIONS
Hypersensitivity Reactions:

  • Serious or severe hypersensitivity reactions have been reported in association with other integrase inhibitors and could occur with CABENUVA
  • Hypersensitivity reactions, including cases of drug reaction with eosinophilia and systemic symptoms (DRESS), have been reported during postmarketing experience with rilpivirine-containing regimens. While some skin reactions were accompanied by constitutional symptoms such as fever, other skin reactions were associated with organ dysfunctions, including elevations in hepatic serum biochemistries
  • Discontinue CABENUVA immediately if signs or symptoms of hypersensitivity reactions develop. Clinical status, including liver transaminases, should be monitored and appropriate therapy initiated. Cabotegravir and rilpivirine oral lead-in may be used to help identify patients who may be at risk of a hypersensitivity reaction

Post-Injection Reactions:

  • Serious post-injection reactions (reported in less than 1% of subjects) were reported within minutes after the injection of rilpivirine, including dyspnea, bronchospasm, agitation, abdominal cramping, rash/urticaria, dizziness, flushing, sweating, oral numbness, changes in blood pressure, and pain (e.g., back and chest). These events may have been associated with accidental intravenous administration and began to resolve within a few minutes after the injection
  • Carefully follow the Instructions for Use when preparing and administering CABENUVA. The suspensions should be injected slowly via intramuscular injection and avoid accidental intravenous administration. Observe patients briefly (approximately 10 minutes) after the injection. If a post-injection reaction occurs, monitor and treat as clinically indicated

Hepatotoxicity:

  • Hepatotoxicity has been reported in patients receiving cabotegravir or rilpivirine with or without known pre-existing hepatic disease or identifiable risk factors
  • Patients with underlying liver disease or marked elevations in transaminases prior to treatment may be at increased risk for worsening or development of transaminase elevations
  • Monitoring of liver chemistries is recommended and treatment with CABENUVA should be discontinued if hepatotoxicity is suspected

Depressive Disorders:

  • Depressive disorders (including depressed mood, depression, major depression, mood altered, mood swings, dysphoria, negative thoughts, suicidal ideation, suicide attempt) have been reported with CABENUVA or the individual products
  • Promptly evaluate patients with depressive symptoms
  • Risk of Adverse Reactions or Loss of Virologic Response Due to Drug Interactions:
    • The concomitant use of CABENUVA and other drugs may result in known or potentially significant drug interactions (see Contraindications and Drug Interactions)
    • Rilpivirine doses 3 and 12 times higher than the recommended oral dosage can prolong the QTc interval
    • CABENUVA should be used with caution in combination with drugs with a known risk of Torsade de Pointes

Long-Acting Properties and Potential Associated Risks with CABENUVA:

  • Residual concentrations of cabotegravir and rilpivirine may remain in the systemic circulation of patients for prolonged periods (up to 12 months or longer). Select appropriate patients who agree to the required monthly or every-2-month injection dosing schedule because non-adherence could lead to loss of virologic response and development of resistance
  • To minimize the potential risk of developing viral resistance, it is essential to initiate an alternative, fully suppressive antiretroviral regimen no later than 1 month after the final injection doses of CABENUVA when dosed monthly and no later than 2 months after the final injections of CABENUVA when dosed every 2 months. If virologic failure is suspected, switch the patient to an alternative regimen as soon as possible

ADVERSE REACTIONS

  • The most common adverse reactions in adults (incidence ≥2%, all grades) treated with CABENUVA were injection site reactions, pyrexia, fatigue, headache, musculoskeletal pain, nausea, sleep disorders, dizziness, and rash
  • The safety of CABENUVA in adolescents is expected to be similar to adults

DRUG INTERACTIONS

  • Refer to the applicable full Prescribing Information for important drug interactions with CABENUVA, VOCABRIA (cabotegravir), or EDURANT (rilpivirine)
  • Because CABENUVA is a complete regimen, coadministration with other antiretroviral medications for the treatment of HIV-1 infection is not recommended
  • Drugs that are strong inducers of UGT1A1 or UGT1A9 are expected to decrease the plasma concentrations of cabotegravir. Drugs that induce or inhibit CYP3A may affect the plasma concentrations of rilpivirine
  • CABENUVA should be used with caution in combination with drugs with a known risk of Torsade de Pointes

USE IN SPECIFIC POPULATIONS

  • Pregnancy: There are insufficient human data on the use of CABENUVA during pregnancy to adequately assess a drug-associated risk for birth defects and miscarriage. Discuss the benefit-risk of using CABENUVA during pregnancy and conception and consider that cabotegravir and rilpivirine are detected in systemic circulation for up to 12 months or longer after discontinuing injections of CABENUVA. An Antiretroviral Pregnancy Registry has been established
  • Lactation: Potential risks of breastfeeding include HIV-1 transmission, developing viral resistance in HIV-positive infants, and adverse reactions in a breastfed infant

For more information, please see full US Prescribing Information for CABENUVAhttps://gskpro.com/content/dam/global/hcpportal/en_US/Prescribing_Information/Cabenuva/pdf/CABENUVA-PI-PIL-IFU2-IFU3.PDF

DOVATO (dolutegravir and lamivudine) tablets
Professional Indication and Important Safety Information

INDICATION

DOVATO is indicated as a complete regimen for the treatment of HIV-1 infection in adults and adolescents 12 years of age and older and weighing at least 25 kg with no antiretroviral treatment history or to replace the current antiretroviral regimen in those who are virologically suppressed (HIV-1 RNA less than 50 copies/mL) on a stable antiretroviral regimen with no history of treatment failure and no known substitutions associated with resistance to the individual components of DOVATO.

IMPORTANT SAFETY INFORMATION

BOXED WARNING: PATIENTS CO-INFECTED WITH HEPATITIS B VIRUS (HBV) AND HIV-1:

EMERGENCE OF LAMIVUDINE-RESISTANT HBV AND EXACERBATIONS OF HBV

All patients with HIV-1 should be tested for the presence of HBV prior to or when initiating DOVATO. Emergence of lamivudine-resistant HBV variants associated with lamivudine-containing antiretroviral regimens has been reported. If DOVATO is used in patients co-infected with HIV-1 and HBV, additional treatment should be considered for appropriate treatment of chronic HBV; otherwise, consider an alternative regimen. Severe acute exacerbations of HBV have been reported in patients who are co-infected with HIV-1 and HBV and have discontinued lamivudine, a component of DOVATO. Closely monitor hepatic function in these patients and, if appropriate, initiate anti-HBV treatment.

CONTRAINDICATIONS

  • Do not use DOVATO in patients with previous hypersensitivity reaction to dolutegravir or lamivudine
  • Do not use DOVATO in patients receiving dofetilide

WARNINGS AND PRECAUTIONS 

Hypersensitivity Reactions:

  • Hypersensitivity reactions have been reported with dolutegravir and were characterized by rash, constitutional findings, and sometimes organ dysfunction, including liver injury
  • Discontinue DOVATO immediately if signs or symptoms of severe skin or hypersensitivity reactions develop, as a delay in stopping treatment may result in a life-threatening reaction. Clinical status, including liver aminotransferases, should be monitored and appropriate therapy initiated

Hepatotoxicity:

  • Hepatic adverse events have been reported, including cases of hepatic toxicity (elevated serum liver biochemistries, hepatitis, and acute liver failure), in patients receiving a dolutegravir-containing regimen without pre-existing hepatic disease or other identifiable risk factors
  • Patients with underlying hepatitis B or C or marked elevations in transaminases prior to treatment may be at increased risk for worsening or development of transaminase elevations with use of DOVATO. In some cases, the elevations in transaminases were consistent with immune reconstitution syndrome or hepatitis B reactivation, particularly in the setting where anti-hepatitis therapy was withdrawn
  • Monitoring for hepatotoxicity is recommended

Embryo Fetal Toxicity:

  • Assess the risks and benefits of DOVATO and discuss with the patient to determine if an alternative treatment should be considered at the time of conception through the first trimester of pregnancy due to the risk of neural tube defects
  • Pregnancy testing is recommended before initiation of DOVATO. Individuals of childbearing potential should be counseled on the consistent use of effective contraception

Lactic Acidosis and Severe Hepatomegaly With Steatosis:

  • Fatal cases have been reported with the use of nucleoside analogs, including lamivudine.
  • Discontinue DOVATO if clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity develop, including hepatomegaly and steatosis in the absence of marked transaminase elevations.

Adverse Reactions or Loss of Virologic Response Due to Drug Interactions with concomitant use of DOVATO and other drugs may occur (see Contraindications and Drug interactions).

Immune Reconstitution Syndrome, including the occurrence of autoimmune disorders with variable time to onset, has been reported with the use of DOVATO.

ADVERSE REACTIONS

The most common adverse reactions (incidence ≥2%, all grades) with DOVATO were headache (3%), nausea (2%), diarrhea (2%), insomnia (2%), fatigue (2%), and anxiety (2%).

DRUG INTERACTIONS

  • Consult full Prescribing Information for DOVATO for more information on potentially significant drug interactions
  • DOVATO is a complete regimen. Coadministration with other antiretroviral medications for the treatment of HIV-1 infection is not recommended
  • Drugs that induce or inhibit CYP3A or UGT1A1 may affect the plasma concentrations of dolutegravir
  • Administer DOVATO 2 hours before or 6 hours after taking polyvalent cation-containing antacids or laxatives, sucralfate, oral supplements containing iron or calcium, or buffered medications. Alternatively, DOVATO and supplements containing calcium or iron can be taken with food

Use in specific populations

  • Pregnancy: There are insufficient human data on the use of DOVATO during pregnancy to definitively assess a drug-associated risk for birth defects and miscarriage. An Antiretroviral Pregnancy Registry has been established. Advise individuals of childbearing potential of the potential risk of neural tube defects. Assess the risks and benefits of DOVATO and discuss with the patient to determine if an alternative treatment should be considered at the time of conception through the first trimester of pregnancy or if pregnancy is confirmed in the first trimester
  • Lactation: Breastfeeding is not recommended due to the potential for HIV-1 transmission, developing viral resistance in HIV-positive infants, and adverse reactions in a breastfed infant
  • Females and Males of Reproductive Potential: Pregnancy testing is recommended before initiation of DOVATO. Counsel individuals of childbearing potential taking DOVATO on the consistent use of effective contraception
  • Renal Impairment: DOVATO is not recommended for patients with creatinine clearance <30 mL/min. Patients with a sustained creatinine clearance between 30 and 49 mL/min should be monitored for hematologic toxicities, which may require a dosage adjustment of lamivudine as an individual component
  • Hepatic Impairment: DOVATO is not recommended in patients with severe hepatic impairment (Child-Pugh Score C)
