In a report issued to mark World AIDS Day on Sunday, UNAIDS said that the number of AIDS death last year — an estimated 630,000 — was at its lowest since peaking in 2004, suggesting the world is now at “a historic crossroads” and has a chance to end the epidemic.
The drug called lenacapavir is already sold under the brand name Sunlenca to treat HIV infections in the U.S., Canada, Europe and elsewhere. The company plans to seek authorization soon for Sunlenca to be used for HIV prevention.
