The US Meals and Drug Administration has simply accredited lenacapavir, an injectable type of HIV prevention that’s virtually one hundred pc efficient and requires solely two doses per 12 months. Science journal described the medication the most necessary scientific advance of 2024.
In scientific trials, lenacapavir proved to be 99.9 % efficient in stopping HIV an infection by means of sexual transmission in folks weighing greater than 35 kilograms. The drug, an antiretroviral, works not by stimulating an immune response, however by blocking HIV from reproducing throughout its early phases—particularly, by disrupting the perform of the virus’s capsid protein.

Winnie Byanyima, govt director of of the Joint United Nations Program on HIV/AIDS (UNAIDS), has additionally flagged up to now that the drug is unaffordable for many individuals in Africa, the place the medication has the potential to have the most important influence. Roughly two-thirds of the folks dwelling with HIV worldwide stay in sub-Saharan Africa.
Gilead mentioned in a assertion final 12 months that it had been “creating a technique to allow broad, sustainable entry globally” to lenacapavir, though the corporate has not but supplied detailed info on the way it will do that. One possibility might be “voluntary licensing,” the place different firms are granted permission to provide and promote generic variations of a patented product solely to folks in sure (usually low-income) nations. Researchers on the College of Liverpool within the UK have calculated {that a} 12 months’s value of lenacapavir might be made out there for as little as $25.
