- Late-Breaking Full Results from
- Progress and Person-Centered Approaches Across HIV Treatment,
- Key Initiatives Demonstrate Commitment to Collaboration to Help End the HIV Epidemic Worldwide -
"The AIDS 2024 conference convenes the global HIV community – scientists, advocates, and partners from the public and private sectors," said
Gilead’s AIDS 2024 program highlights include:
Late-breaking: Full data from pivotal PURPOSE 1 trial: Data evaluating lenacapavir, an investigational, twice-yearly medicine for HIV prevention, will be presented at the Co-Chairs’ Choice session on
Oral presentation: Week 48 outcomes from ARTISTRY-1: The latest data from an ongoing Phase 2/3 study (NCT05502341) designed to evaluate an investigational once-daily single-tablet regimen of bictegravir and lenacapavir in virologically suppressed people with HIV who are on a complex regimen.
Two-year outcomes from BICSTaR: The latest findings from an ongoing global, observational study evaluating the effectiveness, safety and tolerability of Biktarvy® (bictegravir 50 mg/emtricitabine 200 mg/tenofovir alafenamide 25 mg tablets, B/F/TAF) in treatment-naïve and treatment-experienced people with HIV who have a high burden of co-morbidities.
Additional research studies evaluating Biktarvy include five-year outcomes from the pivotal trials evaluating Biktarvy as a long-term treatment option in older adults with a high burden of comorbidities and the Hispanic/Latine community, respectively.
HIV treatment research pipeline findings will also include new data on GS-1720 and GS-4182. Both investigational agents are being clinically evaluated as part of potential future once-weekly oral HIV treatment options. Additionally, resistance analyses from a study evaluating the investigational combination of lenacapavir + teropavimab (GS-5423, TAB) + zinlirvimab (GS-2872, ZAB) will be presented to support previously presented data demonstrating the potential of this combination as a novel, long-acting, twice-yearly treatment option.
Symposia focused on addressing barriers to HIV care and prevention: Two symposia to discuss the latest progress in policies and practical solutions from around the world to help achieve more equitable access to HIV care and services.

There is currently no cure for HIV or AIDS.
About Biktarvy
Biktarvy is a complete HIV treatment that combines three powerful medicines to form the smallest 3-drug, integrase strand transfer inhibitor (INSTI)-based single-tablet regimen (STR) available, offering simple once-daily dosing with or without food, with a limited drug interaction potential and a high barrier to resistance. Biktarvy combines the novel, unboosted INSTI bictegravir, with the Descovy® (emtricitabine 200 mg/tenofovir alafenamide 25 mg tablets, F/TAF) backbone. Biktarvy is a complete STR and should not be taken with other HIV medicines.
About Sunlenca
Sunlenca (300 mg tablet and 463.5 mg/1.5 mL injection) [(lenacapavir)] is a first-in-class, long-acting HIV capsid inhibitor approved in
The multi-stage mechanism of action of Sunlenca’s active pharmaceutical agent, lenacapavir, is distinguishable from other currently approved classes of antiviral agents. While most antivirals act on just one stage of viral replication, Sunlenca is designed to inhibit HIV at multiple stages of its lifecycle and has no known cross resistance exhibited in vitro to other existing drug classes.
Lenacapavir is being evaluated as a long-acting option in multiple ongoing and planned early and late-stage clinical studies in Gilead's HIV prevention and treatment research program. Lenacapavir for HIV prevention is investigational, and its safety and efficacy for this use have not been established. Lenacapavir is being developed as a foundation for potential future HIV therapies with the goal of offering both long-acting oral and injectable options with several dosing frequencies, in combination or as a mono agent, that help address individual needs and preferences of people and communities affected by HIV.
Biktarvy (bictegravir 50 mg/emtricitabine 200 mg/tenofovir alafenamide 25 mg) is indicated as a complete regimen for the treatment of HIV-1 infection in adults and pediatric patients weighing at least 14 kg who have no antiretroviral (ARV) treatment history or to replace the current ARV regimen in those who are virologically-suppressed (HIV-1 RNA <50 copies per mL) on a stable ARV regimen with no known or suspected substitutions associated with resistance to bictegravir or tenofovir.
BOXED WARNING: POST TREATMENT ACUTE EXACERBATION OF HEPATITIS B
- Severe acute exacerbations of hepatitis B have been reported in patients who are coinfected with HIV-1 and HBV and have discontinued products containing emtricitabine (FTC) and/or tenofovir disoproxil fumarate (TDF), and may occur with discontinuation of BIKTARVY. Closely monitor hepatic function with both clinical and laboratory follow-up for at least several months in patients who are coinfected with HIV-1 and HBV and discontinue BIKTARVY. If appropriate, anti-hepatitis B therapy may be warranted.
Contraindications
- Coadministration: Do not use BIKTARVY with dofetilide or rifampin.
Warnings and precautions
- Drug interactions: See Contraindications and Drug Interactions sections. Consider the potential for drug interactions prior to and during BIKTARVY therapy and monitor for adverse reactions.
- Immune reconstitution syndrome, including the occurrence of autoimmune disorders with variable time to onset, has been reported.
-
New onset or worsening renal impairment: Postmarketing cases of renal impairment, including acute renal failure, proximal renal tubulopathy (PRT), and Fanconi syndrome have been reported with tenofovir alafenamide (TAF)–containing products. Do not initiate BIKTARVY in patients with estimated creatinine clearance (
CrCl ) <30 mL/min except in virologically suppressed adults <15 mL/min who are receiving chronic hemodialysis. Patients with impaired renal function and/or taking nephrotoxic agents (including NSAIDs) are at increased risk of renal-related adverse reactions. Discontinue BIKTARVY in patients who develop clinically significant decreases in renal function or evidence of Fanconi syndrome.
Renal monitoring: Prior to or when initiating BIKTARVY and during therapy, assess serum creatinine,CrCl , urine glucose, and urine protein in all patients as clinically appropriate. In patients with chronic kidney disease, assess serum phosphorus. -
Lactic acidosis and severe hepatomegaly with steatosis: Fatal cases have been reported with the use of nucleoside analogs, including
FTC and TDF. Discontinue BIKTARVY 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
- Most common adverse reactions (incidence ≥5%; all grades) in clinical studies through week 144 were diarrhea (6%), nausea (6%), and headache (5%).
Drug interactions
- Prescribing information: Consult the full prescribing information for BIKTARVY for more information on Contraindications, Warnings, and potentially significant drug interactions, including clinical comments.
- Enzymes/transporters: Drugs that induce P-gp or induce both CYP3A and UGT1A1 can substantially decrease the concentration of components of BIKTARVY. Drugs that inhibit P-gp, BCRP, or inhibit both CYP3A and UGT1A1 may significantly increase the concentrations of components of BIKTARVY. BIKTARVY can increase the concentration of drugs that are substrates of OCT2 or MATE1.
-
Drugs affecting renal function: Coadministration of BIKTARVY with drugs that reduce renal function or compete for active tubular secretion may increase concentrations of
FTC and tenofovir and the risk of adverse reactions.
Dosage and administration
-
Dosage: Adult and pediatric patients weighing ≥25 kg: 1 tablet containing 50 mg bictegravir (BIC), 200 mg emtricitabine (FTC), and 25 mg tenofovir alafenamide (TAF) taken once daily with or without food. Pediatric patients weighing ≥14 kg to <25 kg: 1 tablet containing 30 mg BIC, 120 mg
FTC , and 15 mg TAF taken once daily with or without food. For children unable to swallow a whole tablet, the tablet can be split and each part taken separately as long as all parts are ingested within approximately 10 minutes. -
Renal impairment: For patients weighing ≥25 kg, not recommended in patients with
CrCl 15 to <30 mL/min, or <15 mL/min who are not receiving chronic hemodialysis, or <15 mL/min who are receiving chronic hemodialysis and have no antiretroviral treatment history. For patients weighing ≥14 kg to <25 kg, not recommended in patients withCrCl <30 mL/min. - Hepatic impairment: Not recommended in patients with severe hepatic impairment.
- Prior to or when initiating: Test patients for HBV infection.
-
Prior to or when initiating, and during treatment: As clinically appropriate, assess serum creatinine,
CrCl , urine glucose, and urine protein in all patients. In patients with chronic kidney disease, assess serum phosphorus.
Pregnancy and lactation
- Pregnancy: BIKTARVY is recommended in pregnant individuals who are virologically suppressed on a stable ARV regimen with no known substitutions associated with resistance to any of the individual components of BIKTARVY. Lower plasma exposures of BIKTARVY were observed during pregnancy; therefore, viral load should be monitored closely during pregnancy.
- Lactation: Individuals infected with HIV-1 should be informed of the potential risks of breastfeeding.
Sunlenca, a human immunodeficiency virus type 1 (HIV-1) capsid inhibitor, in combination with other antiretroviral(s), is indicated for the treatment of HIV-1 infection in heavily treatment-experienced adults with multidrug resistant HIV-1 infection failing their current antiretroviral regimen due to resistance, intolerance, or safety considerations.
Contraindications
- Coadministration: Concomitant administration of Sunlenca is contraindicated with strong CYP3A inducers.
Warnings and precautions
- Immune reconstitution syndrome, including the occurrence of autoimmune disorders with variable time to onset, has been reported in patients treated with combination antiretroviral (ARV) therapy.
- Long-acting properties and potential associated risks with Sunlenca: Residual concentrations of Sunlenca may remain in the systemic circulation of patients for up to 12 months or longer. Sunlenca may increase exposure, and potential risk of adverse reactions, to drugs primarily metabolized by CYP3A initiated within 9 months after last injection. Counsel patients regarding the dosing schedule because nonadherence could lead to loss of virologic response and development of resistance. If virologic failure occurs, switch to an alternative regimen if possible. If discontinuing Sunlenca, begin alternate suppressive ARV regimen within 28 weeks from last injection.
- Injection site reactions may occur, and nodules and indurations may be persistent.
Adverse reactions
- Most common adverse reactions (incidence ≥3%, all grades) are injection site reactions (65%) and nausea (4%).
Drug interactions
- Prescribing information: Consult the full prescribing information for Sunlenca for more information on Contraindications, Warnings, and potentially significant drug interactions, including clinical comments.
- Enzymes/transporters: Drugs that are strong or moderate inducers of CYP3A may significantly decrease the concentration of Sunlenca. Drugs that strongly inhibit CYP3A, P-gp, and UGT1A1 together may significantly increase the concentration of Sunlenca. Sunlenca may increase the exposure of drugs primarily metabolized by CYP3A, when initiated within 9 months after the last injection of Sunlenca, which may increase the potential risk of adverse reactions.
Dosage and administration
-
Dosage: Initiation with 1 of 2 options, followed by maintenance dosing once every 6 months. Tablets may be taken with or without food.
- Initiation Option 1: Day 1: 927 mg by subcutaneous injection and 600 mg orally (2 x 300-mg tablets). Day 2: 600 mg orally (2 x 300-mg tablets).
- Initiation Option 2: Day 1: 600 mg orally (2 x 300-mg tablets). Day 2: 600 mg orally (2 x 300-mg tablets). Day 8: 300 mg orally (1 x 300-mg tablet). Day 15: 927 mg by subcutaneous injection.
- Maintenance: 927 mg by subcutaneous injection every 26 weeks +/- 2 weeks from date of last injection.
- Missed Dose: During the maintenance period, if more than 28 weeks have elapsed since the last injection and if clinically appropriate to continue Sunlenca treatment, restart the initiation dosage regimen from Day 1, Option 1 or Option 2.
Pregnancy and lactation
- Pregnancy: There is insufficient human data on the use of Sunlenca during pregnancy. An Antiretroviral Pregnancy Registry (APR) has been established.
- Lactation: Individuals infected with HIV-1 should be instructed not to breastfeed, due to the potential for HIV-1 transmission.
