Breakthrough in HIV Prevention: Trial Shows That Twice-Yearly Injection 100% Effective in Women

A major clinical trial in South Africa has yielded promising results for a new HIV prevention medication. The study found that a twice-yearly injection of lenacapavir offered young women 100% protection from HIV infection.
In the Purpose 1 trial study, the researchers compared the effectiveness of three pre-exposure prophylaxis (PrEP) drug:
Lenacapavir, a new injectable medication administered every six months.
Truvada (F/TDF), a daily pill that has been the standard PrEP option for over a decade.
Descovy (F/TAF), a newer daily pill with improved properties.
The most striking finding was the 100% protection from HIV infection observed among the 2,134 women who received lenacapavir injections. In comparison, some women taking daily Truvada (1.5%) and Descovy (1.8%) contracted the virus.
These results highlight the potential benefits of injectable PrEP, particularly for young women in sub-Saharan Africa who often struggle with adherence to daily medications.
Physician-scientist Linda-Gail Bekker, principal investigator for the South African part of the study, writes : ”For a young woman who struggles to get to an appointment at a clinic in a town or who can’t keep pills without facing stigma or violence, an injection just twice a year is the option that could keep her free of HIV.’’
The Purpose 1 trial will continue in an “open label” phase, allowing participants to choose their preferred PrEP option. Additionally, a sister trial ( Purpose 2 ) is underway to assess lenacapavir’s effectiveness among men and transgender individuals.
Over 1.3 million people contracted HIV globally in 2022. This number, though lower than 2010’s 2 million, is still far too high to reach the UNAIDS target of less than 500,000 new infections by 2025.
”We also hope we may begin to see the drug being tested in more studies to understand better how to incorporate it into real world settings. Price is a critical factor to ensure access and distribution in the public sector where it is badly needed.’’ Said Linda-Gail Bekker .

YouTube released an updated eraser tool last week designed to help creators resolve music copyright claims on their videos. Initially reported by TechCrunch , this revamped tool allows creators to effortlessly remove copyright-claimed music without impacting other audio elements, such as dialogue and sound effects.
The announcement about the revamped Erase Song feature was made public last week through a YouTube video and a post by YouTube CEO Neal Mohan on X (formerly Twitter). The post read, “Good news, creators: our updated Erase Song tool helps you easily remove copyright-claimed music from your video (while leaving the rest of your audio intact).”

The company’s YouTube video revealed that the feature had been in beta for some time but was not publicly released earlier due to its inability to produce the desired results accurately. However, with the newly introduced AI-powered algorithm, creators can easily use the eraser tool to accurately detect and remove copyrighted content while keeping other audio in the segment intact.
YouTube also provides alternative options on its support page for cases where the algorithm fails to remove copyrighted content. “This edit might not work if the song is hard to remove. If this tool doesn’t successfully remove the claim on a video, you can try other editing options, such as muting all sound in the claimed segments or trimming out the claimed segments,” the article states.
The tool will be available on both the desktop and mobile versions of the app in the coming weeks.
