Lengthy-acting injectable cabotegravir (CAB-LA) was secure and effectively tolerated as HIV pre-exposure prophylaxis (PrEP) earlier than and through being pregnant within the follow-up section of a world research amongst cisgender ladies. The evaluation of outcomes from greater than 300 pregnancies and infants might be introduced on the 2024 Worldwide AIDS Convention (AIDS 2024) in Munich, Germany.
Cisgender ladies expertise organic adjustments and social dynamics that may improve their chance of buying HIV throughout being pregnant and the postnatal interval, and we have to supply them evidence-based choices when they might want them most. These knowledge present reassurance about long-acting injectable cabotegravir for HIV prevention throughout being pregnant.”

CAB-LA is a extremely efficient HIV prevention technique, administered by intramuscular injection each two months. Nevertheless, knowledge relating to the security of CAB-LA throughout being pregnant are restricted. An open-label extension research of the CAB-LA efficacy trial in cisgender ladies included ladies in a number of nations throughout East and Southern Africa who had the potential to develop into pregnant throughout the longitudinal research and who didn’t have HIV. Members selected between CAB-LA or oral PrEP with tenofovir disoproxil fumarate and emtricitabine and had the choice to make use of contraception in the event that they wished. They had been monitored carefully for security. Members who turned pregnant additionally had been monitored for pregnancy-related antagonistic occasions together with gestational hypertension, pre-eclampsia, and weight achieve, in addition to toddler outcomes, akin to miscarriage, intrauterine fetal dying or stillbirth, untimely beginning, or low birthweight.
There have been 367 pregnancies on this section of the research. Being pregnant-related maternal antagonistic occasion incidence was 45.7, 47.1, and 37.5 per 100 particular person years amongst folks utilizing CAB-LA throughout being pregnant, previous to being pregnant, or with no CAB-LA use, respectively. Hostile toddler outcomes had been comparable throughout teams, with unfavourable outcomes reported in 33%, 38%, and 27% of pregnancies with CAB-LA use, prior CAB-LA use, or no CAB-LA use, respectively. One main congenital anomaly was reported in a participant receiving CAB-LA. No maternal deaths occurred. Being pregnant and toddler outcomes within the research had been much like estimated basic inhabitants outcomes.
Total, CAB-LA was secure and effectively tolerated. These findings display the security of utilizing CAB-LA previous to and through being pregnant.
“The overlap between excessive HIV incidence and the particular dangers that cisgender pregnant ladies face in buying HIV in lots of nations requires various and extremely efficient PrEP choices as a part of sexual and reproductive well being approaches,” mentioned research chair Sinead Delany-Moretlwe, M.B.B.Ch., Ph.D., director of Analysis at Wits RHI and professor of International Well being and Infectious Illnesses on the College of the Witwatersrand, Johannesburg. “We hope that these findings can fill an vital information hole that may assist improve entry to this extremely efficient HIV PrEP choice amongst cisgender ladies earlier than, throughout, and after being pregnant.”
