NCT ID NCT02362503

Ongoing Disease control Sponsor: ViiV Healthcare Source: ClinicalTrials.gov ↗

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study tests a new HIV medicine, fostemsavir, in people whose HIV has become resistant to many other drugs. About 371 adults with multi-drug resistant HIV took part. The goal was to see if fostemsavir could lower the amount of virus in their blood. This is a disease control study, meaning the treatment helps manage HIV but does not cure it.
