ViiV HEALTHCARE SHOWCASES BREADTH OF CLINICAL AND REAL-WORLD EVIDENCE AT EACS AND IDWEEK 2025

London, 9 October 2025 – ViiV Healthcare, the global specialist HIV company majority owned by GSK, with Pfizer and Shionogi as shareholders, today announced the presentation of more than 60 abstracts, including data from its industry-leading long-acting HIV treatment and prevention portfolio, at the 20^th European AIDS Conference (EACS) in Paris, France from 15-18 October, and at IDWeek 2025 in Atlanta, Georgia, US from 19-22 October.

Highlights include initial data from the phase I CLARITY crossover study, the first comparing the acceptability and tolerability of cabotegravir long-acting (CAB LA) and lenacapavir (LEN) injections after a single dose.¹ New effectiveness and tolerability data for Cabenuva (cabotegravir + rilpivirine LA), Apretude (CAB LA for PrEP), and pipeline data on innovative combination approaches in HIV treatment, reinforce ViiV Healthcare’s leadership in HIV long-acting innovation.

New clinical data assessing acceptability and tolerability of single-dose CAB LA and LEN injections: At EACS, initial data from a primary analysis of the phase I CLARITY study – a randomised crossover study of long-acting injectable antiretrovirals in 63 HIV-negative adults – will highlight acceptability and tolerability of CAB LA vs LEN following a single dose.¹ The study will show clinically relevant differences in injection site reactions (ISRs) experienced by participants following administration.

New real-world evidence for CAB LA for PrEP: At IDWeek, a range of studies will provide insights into the real-world data of CAB LA in HIV prevention including: the PrEPFACTS study, which will reveal US testing patterns and evidence of HIV; US data on HIV testing from the OPERA cohort, which will report on how CAB LA or oral PrEP is administered in the real world to help support optimal HIV care; interim findings from the phase IV EBONI study on Black women’s experiences of CAB LA, providing insights from a group that accounts for approximately half of new HIV diagnoses among women in the US.^2,3,4,5

Reinforcing the established data for HIV treatment with cabotegravir + rilpivirine (CAB+RPV LA) in a broad range of populations: At EACS, a meta-analysis of 26 studies involving more than 7,000 virologically suppressed people living with HIV will provide real-world effectiveness, adherence and tolerability data for CAB+RPV LA.⁶ At IDWeek, a four-year analysis from the OPERA cohort of length of time people stay on CAB+RPV LA and their virologic outcomes across age groups provides insights into its use and effectiveness over time.⁷

Key ViiV Healthcare sponsored or supported studies to be presented at IDWeek 2025:

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

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)
