Reformulation of HIV prevention drug lenacapavir makes it last for a year

A team of pharmaceutical researchers at biopharma company Gilead Sciences has announced that a reformulation of its HIV prevention drug lenacapavir allows it to persist in the body for up to a year. In their paper published in The Lancet journal, the group describes how they injected the new formulation into several HIV-free volunteers and tested them for up to a year, and what they found in doing so.
