Lenacapavir, sold under the brand name Sunlenca, is an antiretroviral medication used to treat HIV/AIDS.[10] It is taken by mouth or by subcutaneous injection.[10]

The most common side effects include reactions at the injection site and nausea.[10][11]

Lenacapavir was approved for medical use in the European Union in August 2022,[10][12] in Canada in November 2022,[5][6] and in the United States in December 2022.[11][13][14] It is the first of a class of drugs called capsid inhibitors to be FDA-approved for treating HIV/AIDS.[11][15]

Medical uses[edit]

Lenacapavir, in combination with other antiretrovirals, is indicated for the treatment of HIV/AIDS. It is used in heavily treatment-experienced adults with multiple drug resistance in whom current antiretroviral therapy is ineffective due to resistance, intolerance or safety considerations.[9][11]

Mechanism of action[edit]

Lenacapavir works by binding directly to the interface between HIV-1 viral capsid protein (p24) subunits in capsid hexamers, interfering with essential steps of viral replication, including capsid-mediated nuclear uptake of HIV-1 proviral DNA, virus assembly and release, production of capsid protein subunits, and capsid core formation.[11][16] The US Food and Drug Administration considers it to be a first-in-class medication.[15][17]

History[edit]

Lenacapavir was developed by Gilead Sciences.[18]

As of 2021, it is in phase II/III clinical trials.[19] It is being investigated as a treatment for HIV patients infected with multidrug-resistant virus and as a twice-yearly injectable for pre-exposure prophylaxis.[19][20]

The safety and efficacy of lenacapavir were established through a multicenter clinical trial with 72 participants whose HIV infections were resistant to multiple classes of HIV medications.[11] These participants had to have high levels of virus in their blood despite being on antiretroviral drugs.[11] Participants were enrolled into one of two study groups.[11] One group was randomized to receive either lenacapavir or placebo in a double-blind fashion, and the other group received open-label lenacapavir.[11] The primary measure of efficacy was the proportion of participants in the randomized study group who achieved a certain level of reduction in virus during the initial 14 days compared to baseline.[11]

As of 2023, lenacapavir was approved by the FDA and EMA for people with limited treatment options.[9] Studies have also been conducted for its use in treatment-naive individuals.[21] For virally suppressed individuals switching treatment, early studies have tested lenacapavir injections in combination with infusions of the broadly neutralising antibodies teropavimab and zinlirvimab (a twice yearly regimen)[22] as well as lenacapavir with islatravir (a weekly oral regimen).[23]

The U.S. Food and Drug Administration granted the application for lenacapavir priority review, fast track, and breakthrough therapy designations.[11]

Society and culture[edit]

Legal status[edit]

On 23 June 2022, the Committee for Medicinal Products for Human Use of the European Medicines Agency adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Sunlenca, intended for the treatment of adults with multidrug‑resistant human immunodeficiency virus type 1 (HIV‑1) infection.[24] The applicant for this medicinal product is Gilead Sciences Ireland UC.[24]

Lenacapavir was approved for medical use in the European Union in August 2022,[10][25] in Canada in November 2022,[5][6] and in the United States in December 2022.[11]
