You by no means hear “100%” in medication. The trial was probably the most profitable we’ve ever seen for HIV prevention. The drug was secure, too (it’s already authorized to deal with HIV infections). And it solely wanted to be injected twice a 12 months to supply full safety.
This week, the outcomes of a small part I trial for as soon as-yearly lenacapavir injections had been introduced at a convention in San Francisco. These early “first in human” trials are designed to check the security of a drug in wholesome volunteers. Nonetheless, the outcomes are extremely promising: All of the volunteers nonetheless had the drug of their blood plasma a 12 months after their injections, and at ranges that earlier research recommend will defend them from HIV infections.
I don’t usually get too enthusiastic about part I trials, which often contain only a handful of volunteers and usually don’t inform us a lot about whether or not a drug is more likely to work. However this trial appears to be totally different. Collectively, the lenacapavir trials may convey us a big step nearer to ending the HIV epidemic.
First, a fast recap. We’ve had efficient pre-exposure prophylactic (PrEP) medicine for HIV since 2012, however these should be taken both day by day or simply earlier than an individual is uncovered to the virus. In 2021, the US Meals and Drug Administration authorized the primary long-acting injectable drug for HIV prevention. That drug, cabotegravir, must be injected each two months.
However researchers have been engaged on medicine that provide even longer-lasting safety. It may be troublesome for folks to recollect to take day by day tablets once they’re sick, not to mention once they’re wholesome. And these medicines have a stigma hooked up to them. “Individuals are involved about folks listening to the tablets shake of their purse on the bus … or seeing them on a medication cupboard or bedside desk,” says Moupali Das, vice chairman of HIV prevention and virology, pediatrics, and HIV medical improvement at Gilead Sciences.
