Gilead 's experimental twice-yearly medicine to prevent HIV was 100% effective in a late-stage trial, the company said Thursday. The results bring Gilead one step closer to introducing a new form of pre-exposure prophylaxis, or PrEP, and broadening its HIV business. If those results are positive, the company could bring lenacapavir for PrEP to market as soon as late 2025. RBC Capital Markets analyst Brian Abrahams expects Gilead's shot will significantly increase the number of people interested in preventive HIV medicine. In its statement disclosing the lenacapavir trial results Thursday, Gilead said it plans to share an update on how it plans to address access in such countries where people suffer high incidence rates of HIV.
