Vfend - voriconazole

Pfizer · Phase 3 active Small molecule Under review Quality 0/100

Vfend - voriconazole is a Azole antifungal Small molecule drug developed by Pfizer. It is currently in Phase 3 development for Treatment of invasive aspergillosis, candidemia, and other serious fungal infections. Also known as: Vfend.

Voriconazole is an antifungal medication that works by inhibiting the synthesis of ergosterol, an essential component of fungal cell membranes.

Voriconazole, also known as Vfend, is a small molecule inhibitor that targets the cytochrome P450 51 enzyme, specifically inhibiting lanosterol 14-alpha demethylase. It is used to treat various conditions, including coronavirus infection (COVID-19), according to ClinicalTrials.gov.

Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Anti-infectives pathway favourability +2.0pp
    Microbiological endpoints + non-inferiority designs raise approval rates above baseline.
  • Big-pharma sponsor +3.0pp
    Pfizer is a top-20 pharma sponsor — historical approval rates run ~3pp above average due to scale, regulatory experience, and trial-design quality.
Predicted approval windows by jurisdiction (conditional on FDA approval)

Mechanism of action

It achieves this by targeting the enzyme lanosterol 14α-demethylase, which is necessary for the conversion of lanosterol to ergosterol. This disruption of ergosterol synthesis ultimately leads to the death of fungal cells. Voriconazole has a broad spectrum of activity, making it effective against a wide range of fungal pathogens.
