The mixture of Merck’s islatravir as well as Gilead’s lenacapavir, which the biopharma sells as Sunlenca, always kept HIV-1 RNA below fifty copies/mL in 98% of people after 24 weeks of once-weekly dosing.
The number for Gilead’s once-daily Biktarvy, the command procedure, was actually 100%.Gilead and Merck continued to track clients through Full week 48 and discussed the follow-up information throughout a dental session at IDWeek 2024.

No individuals ceased due to a decrease in CD4+ T-cell or even lymphocyte matters.The mixture is now entering period 3.
Gilead is launching two essential tests that will each randomize 600 virologically decreased grownups to obtain its once-weekly mixture or even the once-daily Biktarvy. The major endpoints of the tests are checking out the proportion of attendees with HIV-1 RNA of 50 copies/mL or fewer at Full week 48..
