In July 2024, we revealed a narrative with the headline: “One of many 7 folks cured of HIV tells his story. Can his remedy work for others.” This summer season, on the Worldwide AIDS Society convention, got here information of an thrilling new improvement within the the continuing effort to carry the epidemic to an finish. This story is the primary in our annual finish of August sequence, “No matter occurred to …”
KIGALI, Rwanda — In a landmark first for the continent hardest hit by HIV, a brand new medical trial in South Africa has delivered a uncommon however extraordinary final result: One younger lady could also be cured of the virus.
The story begins in Might 2016 when Anele bought a name from nurses at an area medical analysis middle in Umlazi township, which lies in South Africa’s southeastern province of KwaZulu-Natal. They informed her she wanted to come back in for an pressing appointment, earlier than breaking the information in individual that she had examined optimistic for HIV. She felt like her world had ended.
“I cried loads,” recalled Anele, now 32, chatting with a bunch of assembled scientists, medical doctors and well being officers on the primary day on the Worldwide AIDS Society (IAS) convention in Kigali, Rwanda in mid-July. “I used to be solely 23. That day, I used to be not OK in any respect.” Anele defined on the IAS convention that she didn’t need to be totally recognized as a result of ongoing stigma related to being HIV optimistic in Umlazi.
It might not have felt prefer it on the time, however in contrast with the estimated 5.2 million different girls dwelling with HIV in South Africa, Anele was lucky. Her early analysis and therapy plan had been solely potential due to a brand new social empowerment and medical program referred to as FRESH (Females Rising by way of Schooling, Assist and Well being) which had begun in Umlazi again in 2012. Six years after Anele’s analysis, this program would see her enrolled within the first-ever medical trial to try to remedy HIV sufferers in Africa.
A trial born in Umlazi
Based on a July 2025 article within the medical journal The Lancet, 10 folks worldwide are thought-about cured of HIV after receiving stem cell transplants to deal with aggressive blood most cancers, which occurred to destroy the virus. However that methodology will not be thought-about secure or scalable. Lately different “remedy trials” have explored newer approaches together with gene modifying and CAR T-cell remedy to reinforce immune response, however they’ve but to yield profitable outcomes.
However virtually all of those trials have taken place within the U.S. But 67% of the 40.8 million folks dwelling with HIV are in Africa the place genetic and demographic profiles are remarkably completely different, stated Thumbi Ndung’u, a professor on the College of KwaZulu-Natal, Durban, who led the lab work for the trial.
“Within the West, the epidemic is predominantly in white, gay males, whereas in Africa, nearly all of folks dwelling with HIV are typically youthful and feminine,” Ndung’u informed NPR.
This issues for a number of causes. Organic responses to HIV differ between women and men, influenced by intercourse hormones. But, stated Krista Dong, assistant professor at Harvard Medical Faculty and FRESH’s medical director, girls are vastly underrepresented in remedy trials. “Girls make up 53% of world HIV infections, however they’re grossly underrepresented,” Dong famous.

The biology of the virus additionally varies by area. Whereas the dominant HIV pressure in North America and Europe is clade B, sub-Saharan Africa sees largely clades A, C, and D. Clade C, the world’s most typical subtype, has distinct options in the way it interacts with the immune system, which probably impacts the success of healing therapies.
“To develop a remedy intervention that has an affect, now we have to ensure it’s one thing that works in Africa,” Ndung’u stated. “And the one means we will make sure that’s the case is by really doing the trials in these populations.”
A technique of kick and kill
FRESH has taken a special method from earlier HIV packages. In KwaZulu-Natal, researchers have lengthy famous that younger girls are significantly weak to an infection as a result of socioeconomic components, together with monetary dependence on male companions and restricted entry to training or employment.
Launched in 2012 in Umlazi, the place greater than 60% of younger girls contract HIV earlier than age 23, FRESH provided twice-weekly HIV testing together with an empowerment curriculum that included classes on vanity and gender-based violence in addition to profession mentoring. Initially funded by personal philanthropy and later the Gates Basis, this system helped members resume education or acquire employment, whereas permitting researchers to detect HIV infections inside days. (The Gates Basis is a sponsor of NPR and this weblog.)
Having such frequent testing meant that the FRESH group might determine new HIV infections inside a matter of days, enabling girls to right away begin antiretroviral treatment to suppress the virus, limiting the scale and variety of the viral reservoir. In principle, they’d be simpler to remedy.
In 2022, the medical trial started. Twenty girls enrolled, together with Anele. All of them had been on antiretroviral remedy for a mean of seven years. Sponsored by California-based drugmaker Gilead Sciences, the trial used a brand new technique: It aimed to flush HIV out of hiding, then neutralize it.
The method used a novel drug referred to as vesatolimod to kick HIV out of its hiding locations within the physique, adopted by a one-time infusion of broadly neutralizing antibodies (bNAbs) on day seven. These antibodies, tailor-made to focus on clade C, would bind to the virus and summon immune cells to get rid of it.
“HIV does not dwell in our blood, it lives in reservoirs whether or not within the lymph nodes or the liver or the mind, so it’s worthwhile to kick it out, in order that the bNAbs can attain it,” Dong stated. “So what we had been going for was this technique of kick and kill.”
Over 20 weeks, members acquired vesatolimod biweekly. Then, on day 35, they had been requested to cease their antiretrovirals.
They’d entry to counselors and a neighborhood advisory board from the College of KwaZulu-Natal and FRESH workers, assuring that they’d be monitored extraordinarily carefully. However after they had been first recognized, nurses had emphasised that they would wish to take antiretrovirals for the remainder of their lives. Stopping this therapy got here as a shock.
The antiretroviral pause additionally carried actual dangers. When HIV rebounds, it may well trigger irritation and lift the chance of transmission, however as Ndung’u defined, stopping this therapy is at present the one option to assess whether or not a affected person is really in remission. “We needed to be sure that the members totally understood the dangers,” he stated.
Inside a yr, 16 members noticed their virus rebound and resumed therapy — however 4 remained in remission, with undetectable viral masses.
Doubtlessly cured
Within the coming years, understanding what set the 4 girls who stayed in remission aside might yield very important clues about who may profit most from this therapy method.
Whereas Ndung’u and Dong do not but have agency solutions, they’ve hypotheses. Ndung’u suspects genetic components might have helped the 4 girls mount a simpler immune response. Dong is investigating why the remedy failed within the different 16 – whether or not their viral reservoirs had been bigger or their immune programs reacted negatively to one of many medicine. Unraveling these variations might be key to enhancing future methods.
The pair are wanting to proceed. Ndung’u hopes to launch a trial involving girls contaminated at an unknown time — representing a extra typical HIV inhabitants and probably giving the antibodies extra viral materials to behave on.
There’s additionally rising curiosity in how future remedy trials may embody members with co-infections frequent in sub-Saharan Africa, equivalent to tuberculosis or hepatitis B. “That is a novel however necessary problem,” Helena Lamptey, an immunology researcher on the College of Ghana, informed NPR. “Many individuals with HIV have co-infections that are impacting the immune system and probably serving to HIV to persist.” Treatment methods might want to mirror that actuality.
For now, FRESH stands as a milestone. Of the 4 girls who remained in remission on the trials’ finish, one later skilled a viral rebound. Two others selected to renew antiretrovirals – one for comfort after beginning a brand new job that made weekly monitoring tough, and the opposite to make sure a secure being pregnant.
That leaves Anele. Greater than two years after stopping treatment, she stays HIV-free and off therapy. Whereas she stays cautious about declaring herself cured, Dong believes that it’s a very actual risk.
Her case is fueling curiosity throughout the area. Researchers in nations equivalent to Botswana have expressed the will to run their very own trials. With different new therapy potentialities rising equivalent to therapeutic vaccines and extra superior, long-lasting antibody infusions which Dong calls “tremendous bNAbs,” there’s real optimism {that a} nook has lastly been turned for folks with HIV in Africa.
“Though the FRESH trial was not a house run, reaching long-term viral management in 20% of the members is thrilling,” Dong stated. “It has introduced hope to the neighborhood that progress is being made.”
