Fostemsavir Compassionate Use Named Patient Program for the Treatment of Human Immunodeficiency Virus 1 (HIV-1)

Fostemsavir (FTR) is the prodrug of temsavir (TMR), which is a novel, first-in-class attachment inhibitor being developed as a potential treatment of HIV-1 infection. Investigational FTR is being made available on a compassionate use named patient basis for the treatment of HIV infection in individuals with multidrug resistant HIV-1 infection who are experiencing virologic failure (confirmed HIV-1 RNA ≥1000 c/mL) and are unable to comprise a suppressive regimen with currently available antiretrovirals. Such patients, who are often heavily treatment experienced (HTE), represent a small and highly vulnerable subgroup within the overall HIV patient population. The care of HTE patients is difficult and often complicated by the presence of complex comorbidities, extensive concomitant medication profiles, and advanced HIV disease.
