Brazil pushes HIV remission breakthroughs and new injectable PrEP
Scientists presented two additional cases of HIV remission at the 26th International AIDS Conference in Rio de Janeiro, raising the global total to 13. Both patients – a 21‑year‑old man from Kansas City, USA, and a patient from Essen, Germany – received hematopoietic stem‑cell transplants from donors carrying the CCR5‑delta32 mutation. After the transplants they stopped antiretroviral therapy and have remained with undetectable viral loads for 12 and 14 months respectively.
Brazil’s Ministry of Health, led by Alexandre Padilha, announced a series of agreements to expand HIV prevention. A memorandum with Fiocruz and the pharmaceutical company MSD will advance the development of Alimatravir (MK‑8527), an oral pre‑exposure prophylaxis (PrEP) still in phase‑3 trials and awaiting ANVISA approval. The Ministry also submitted a request to the Conitec committee to incorporate the injectable PrEP cabotegravir into the public SUS system by the end of the year, negotiating a price it described as “adequate” with GSK. Negotiations for the six‑month injectable lenacapavir failed because Gilead’s price was deemed unaffordable, even though Brazil said it was prepared to pay up to ten times the amount offered to comparable countries.
A Fiocruz‑led trial of lenacapavir involving 668 volunteers reported efficacy close to 100 % and high adherence, but the drug remains unavailable to SUS pending a resolution of the price dispute.
