“An effective antiretroviral regimen can be devised for most people living with the virus; however, some people living with HIV no longer have durable viral suppression due to resistance to multiple classes of antiretroviral therapies,” said
Despite the significant advances in ARV therapy, there remain numerous critical and pressing unmet needs for people living with HIV. This is particularly true for individuals who are heavily treatment experienced – which account for an estimated 2% of adults living with HIV who are on treatment globally –- and are unable to maintain virologic suppression due to resistance, intolerance or safety considerations. This type of complexity further increases the chance of treatment failure, underscoring the need for new treatment options that are active against resistant variants of the virus with a novel mechanism of action.
Lenacapavir is a breakthrough innovation with the potential to be a preferred and versatile foundational long-acting agent due to its therapeutic potency and a range of dosing frequencies and routes of administration. Lenacapavir is being developed as a foundation for Gilead’s future HIV therapies with the goal of offering several long-acting options that help address individual needs and preferences that may help optimize outcomes and reduce burden of care. Lenacapavir is being studied in multiple ongoing early and late-stage development programs and has the potential to offer a diverse set of person-centric options for treatment and prevention that could uniquely fit into the lives of people living with HIV and people who would benefit from pre-exposure prophylaxis (PrEP). The use of lenacapavir for HIV prevention is investigational and the safety and efficacy of lenacapavir for this use have not been established.
“This news is an important milestone in the work to help end the HIV epidemic as Sunlenca is now the only FDA-approved twice-yearly treatment for people with multi-drug resistant HIV,” said Daniel O’Day, Chairman and Chief Executive Officer,
The FDA approval for Sunlenca is supported by data from the Phase 2/3 CAPELLA trial, which evaluated lenacapavir in combination with an optimized background regimen in people with multi-drug resistant HIV-1 who are heavily treatment experienced. CAPELLA participants had undergone previous treatment with a median of nine antiretroviral medications. In this patient population with significant unmet medical need, 83% (n=30/36) of participants randomly allocated to receive lenacapavir in addition to an optimized background regimen achieved an undetectable viral load (<50 copies/mL) at Week 52. Additionally, these participants achieved a mean increase in CD4 count of 82 cells/µL. These data were presented at the 29th Conference on Retroviruses and Opportunistic Infections (virtual CROI 2022).
Sunlenca was reviewed and approved as a medication with FDA Breakthrough Therapy Designation, which is intended to expedite the development and review of new drugs which may demonstrate substantial improvement over available therapy. In

About CAPELLA (NCT04150068)
CAPELLA is a Phase 2/3, double-blinded, placebo-controlled global multicenter study designed to evaluate the antiviral activity of lenacapavir administered every six months as a subcutaneous injection in heavily treatment-experienced people with multi-drug resistant HIV-1 infection. CAPELLA includes men and women with HIV-1 and is being conducted at research centers in
In CAPELLA, 36 participants with multi-class HIV-1 drug resistance and a detectable viral load while on a failing regimen were randomly allocated to receive oral lenacapavir or placebo in a 2:1 ratio for 14 days, in addition to continuing their failing regimen (functional monotherapy). An additional 36 participants were enrolled in a separate treatment cohort. Both cohorts are part of the ongoing maintenance period of the study evaluating the safety and efficacy of subcutaneous lenacapavir administered every six months in combination with an optimized background regimen. The primary endpoint was the proportion of participants randomly allocated to receive lenacapavir or placebo for 14 days, in addition to continuing their failing regimen, achieving ≥0.5 log10 copies/mL reduction from baseline in HIV-1 RNA at the end of the functional monotherapy period. The study found that 88% of participants receiving lenacapavir (n=21/24) experienced at least a 0.5 log10 reduction in HIV-1 viral load by the end of 14 days of functional monotherapy as compared with 17% of those receiving placebo (n=2/12).
Following the 14-day functional monotherapy period, participants randomly allocated to receive lenacapavir or placebo, in addition to continuing their failing regimen, started open-label lenacapavir and an optimized background regimen, while those enrolled in a separate treatment cohort received open-label lenacapavir and an optimized background regimen on Day 1. This ongoing maintenance period is evaluating the additional study endpoints of safety and efficacy of subcutaneous lenacapavir administered every six months in combination with an optimized background regimen.

Sunlenca (300 mg tablet and 463.5 mg/1.5 mL injection) is a first-in-class, long-acting HIV capsid inhibitor approved in
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.
- 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.
- Most common adverse reactions (incidence ≥3%, all grades) are injection site reactions (65%) and nausea (4%).
- 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.
