FOSTER CITY, Calif.--(BUSINESS WIRE)--Gilead Sciences, Inc. (Nasdaq: GILD) today announced that the company’s Marketing Authorization Application (MAA) for lenacapavir, an investigational, long-acting HIV-1 capsid inhibitor, has been fully validated and is now under evaluation with the European Medicines Agency (EMA). The proposed indication is for the treatment of HIV-1 infection, in combination with other antiretroviral(s), in adults with multidrug resistant HIV-1 infection who are currently on a failing antiretroviral treatment regimen due to resistance, intolerance or safety considerations.
The application will be reviewed by the EMA’s Committee for Medicinal Products for Human Use (CHMP) under the centralized licensing procedure for all 27 Member States of the European Union, as well as Norway, Iceland and Liechtenstein.
“Lenacapavir is a breakthrough innovation that has the potential to be transformative for people with multi-drug resistant HIV, who have very limited treatment options,” said Merdad Parsey, MD, PhD, Chief Medical Officer, Gilead Sciences. “The MAA validation is a step forward in our commitment to a patient-centered approach to helping all individuals living with HIV achieve and sustain viral load suppression, irrespective of their prior treatment history.”
The MAA is supported by data from the ongoing CAPELLA study, which achieved its primary endpoint by demonstrating that a significantly higher proportion of participants randomly allocated to receive oral lenacapavir in combination with an optimized background regimen (n=24) achieved a clinically meaningful viral load reduction of at least 0.5 log10 copies/mL from baseline compared with those randomly allocated to receive placebo (n=12) during the 14-day functional monotherapy period (88% vs. 17%, p<0.0001). Lenacapavir was generally well-tolerated, with no serious adverse events related to study drug and no study drug discontinuations through the 14-day period, including no discontinuations due to adverse events. The most common adverse events observed were injection site reactions. These data were previously presented at the virtual 28th Conference on Retroviruses and Opportunistic Infections (virtual CROI 2021). 26-week data from the CAPELLA study were presented at the 11th International AIDS Society (IAS) Conference on HIV Science. Additional data from the CAPELLA study will be presented at a future scientific conference.
In June 2021, Gilead submitted a New Drug Application (NDA) for lenacapavir seeking U.S. Food & Drug Administration (FDA) approval for the treatment of HIV-1 infection in heavily treatment-experienced people with multi-drug resistant HIV-1 infection in combination with other antiretrovirals. In May 2019, the FDA granted Breakthrough Therapy Designation for the development of lenacapavir for the treatment of HIV-1 infection in heavily treatment-experienced patients with multi-drug resistance in combination with other antiretroviral drugs.
Lenacapavir is an investigational compound and is not approved by any regulatory authority for any use; its safety and efficacy are not established. There is no cure for HIV or AIDS.
About CAPELLA (NCT04150068)
CAPELLA is a Phase 2/3, double-blinded, placebo-controlled global multi-center study designed to evaluate the antiviral activity of Gilead’s investigational, long-acting HIV-1 capsid inhibitor 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 living with HIV-1 and is being conducted at research centers in North America, Europe and Asia.
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, starting oral lenacapavir on Day 1. 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. Following 14 days of lenacapavir oral therapy, all participants started open-label lenacapavir, administered as a subcutaneous injection every six months, in combination with an optimized background regimen. This ongoing maintenance period of the study is evaluating the additional trial endpoints of safety and efficacy of subcutaneous lenacapavir administered every six months in combination with an optimized background regimen.

About Lenacapavir
Lenacapavir is a potential first-in-class, long-acting HIV-1 capsid inhibitor in development for the treatment of HIV-1 infection. The safety and efficacy of lenacapavir are being evaluated in multiple ongoing clinical studies. Lenacapavir's multi-stage mechanism of action is distinguishable from currently approved classes of antiviral agents and is designed to provide a new avenue for the development of long-acting therapy options for people living with HIV-1. While most antivirals act on just one stage of viral replication, lenacapavir is designed to inhibit HIV-1 at multiple stages of its lifecycle and has no known cross resistance to other existing drug classes.
