IntroductionLenacapavir, also known as Ibalizumab-uiyk, is a humanized monoclonal antibody that is used as an antiviral agent in the treatment of HIV-1 infection. It is designed to target the CD4 receptor on human T cells and prevent the attachment of the virus to the host cell. Lenacapavir | CAS#2189684-58-8has recently been approved by the US Food and Drug Administration (FDA) for treating HIV-1 in adults who have failed multiple antiretroviral therapies. This article will review the properties, mechanism of action, clinical trials, and future prospects of Lenacapavir.PropertiesLenacapavir is a subcutaneously administered drug with a half-life of approximately 17 days. The dose is 2000 mg every four weeks and is intended for use in combination with other antiretroviral agents. It has a molecular weight of approximately 147 kDa and is formulated as a sterile, preservative-free, and clear to slightly opalescent solution. Lenacapavir is classified as an IgG4 kappa monoclonal antibody and is produced by recombinant DNA technology.Mechanism of ActionLenacapavir binds to the CD4 receptor of host T cells, thereby blocking the entry of HIV-1 into the cell and preventing viral replication. Unlike existing antiretroviral agents, Lenacapavir works by a non-competitive mechanism and does not induce drug resistance. It has been shown to have a unique resistance profile that is distinct from other antiretroviral agents. Lenacapavir does not interact with the cytochrome P450 enzyme system and has no significant drug-drug interactions.Clinical TrialsThe safety and efficacy of Lenacapavir were assessed in a Phase 3 randomized, double-blind, placebo-controlled trial (TMB-301) involving 335 HIV-positive adults who had previously failed multiple antiretroviral therapies. The primary endpoint was the proportion of patients achieving viral suppression (<50 copies/mL) at week 26. The trial demonstrated that Lenacapavir, when used in combination with optimized background therapy, achieved a statistically significant higher rate of viral suppression compared to placebo. The most common adverse events were injection site reactions, diarrhea, and headache.Future ProspectsLenacapavir represents a promising addition to the arsenal of antiretroviral agents for the treatment of HIV-1 infection. It offers a new mechanism of action, a unique resistance profile, and a long-acting dosing regimen. The approval of Lenacapavir by the FDA is a significant milestone in the development of HIV therapeutics. Further clinical studies are underway to assess the use of Lenacapavir in novel regimens, including in combination with other long-acting agents. Lenacapavir has the potential to transform the treatment of HIV-1 infection and improve the quality of life for people living with HIV.ConclusionLenacapavir is a new antiretroviral agent that has recently been approved by the FDA for the treatment of HIV-1 in adults who have failed multiple antiretroviral therapies. It works by blocking the attachment of the virus to the CD4 receptor of host T cells, thereby preventing viral replication. The drug has a long half-life, a unique resistance profile, and a favorable safety profile. Lenacapavir has the potential to become a mainstay in the treatment of HIV-1 and improve the health outcomes of people living with HIV.Lenacapavir | CAS#2189684-58-8, antiretroviral therapy, TMB-301, FDA, viral suppressionLenacapavir: A New Antiretroviral Agent for HIV-1 TreatmentLenacapavir, recently approved by the FDA, is a new antiretroviral agent used in treating HIV-1 infection.

CAS NO.2189684-44-2 Lenacapavir API: An OverviewCAS NO.2189684-44-2 Lenacapavir API is a novel antiviral agent that targets HIV-1. It is a long-acting HIV-1 capsid inhibitor that interferes with the viral capsid core assembly, preventing the virus from replicating. Lenacapavir is currently in clinical development and shows promising results in HIV-1-infected individuals, including those who are resistant to existing therapies.Lenacapavir Mechanism of ActionLenacapavir API primarily targets the HIV-1 capsid protein, specifically binding to the NTD pocket. This leads to the formation of aberrant capsid complexes, rendering the virions incapable of completing reverse transcription and ultimately resulting in HIV-1 replication inhibition.PharmacokineticsLenacapavir exhibits a long half-life, allowing for weekly dosing with sustained plasma concentrations and HIV-1 replication inhibition. With an oral bioavailability of 66-77%, lenacapavir is absorbed rapidly and distributes throughout the body, including to HIV-1 reservoir sites.Clinical TrialsVarious phase 1 and 2 studies have been conducted to assess the safety and efficacy of lenacapavir in different HIV-1-infected populations, including treatment-experienced individuals, those with multi-drug-resistant HIV-1, and those living with HIV-1 who have never received antiretroviral therapy. These trials have demonstrated that lenacapavir is well-tolerated, with minimal side effects, and effective in reducing HIV-1 viral load.Potential Combination TherapiesLenacapavir therapy can be notably potentiated when used in combination with other antiretroviral drugs that target diverse stages of the HIV-1 lifecycle, including reverse transcriptase inhibitors and integrase inhibitors. The synergistic effect of such combination therapies could prove highly effective in suppressing viral replication and enhancing treatment efficacy.Resistance ProfileDifferent resistance pathways have been identified in vitro that lead to the emergence of lenacapavir-resistant viral strains. However, clinical trials have demonstrated that lenacapavir retains antiviral activity against strains resistant to other antiretroviral agents, such as protease inhibitors and nucleoside reverse transcriptase inhibitors.Safety ConcernsIn clinical trials, lenacapavir has shown a benign adverse reaction profile, with mostly mild or moderate side effects, including transient injection site reactions, gluteal pain, and headache. Lenacapavir efficacy and safety in pregnant and breastfeeding women remain unclear and require more research.Current StatusLenacapavir API is currently in phase 2/3 clinical trials examining its safety and efficacy in combination with other HIV-1 therapies in both HIV-1-infected and HIV-1-uninfected individuals. The trials are ongoing, with results expected in the near future.Future OutlookLenacapavir shows great potential as a long-acting, weekly dosing antiviral agent that can enhance the treatment options for those living with HIV-1, especially individuals who are resistant to existing therapies. Further clinical trials and research are needed to establish the optimal combination therapies and dosing regimens that can maximize lenacapavir's therapeutic potential.
