Trial Activity: Mature 5 active trials
CNS Approved 2020-07-02

Byfavo is used to help adult patients achieve and maintain sedation during short medical procedures. It is specifically intended for clinical interventions that last 30 minutes or less. This injectable medication helps clinicians manage a patient's level of consciousness during these brief sessions.

How BYFAVO Works

This drug works by binding to benzodiazepine sites on GABA A receptors in the brain to produce a sedative effect. It does not show a preference for any specific subtype of these receptors. While the medication eventually breaks down into a metabolite, that byproduct has a significantly lower ability to bind to the receptors than the drug itself.

How We Calculate These Metrics

Trial Activity Stage

Measures the current development activity pattern based on trial phases, status, and trends. Important: This measures R&D activity, not commercial lifecycle.

Trial statuses: "Active" means recruiting or ongoing. "Completed" means reached planned endpoint. "Terminated" means stopped early—often due to safety, efficacy, or business reasons.

  • Growth: High proportion of early-phase trials (Phase 1/2), active development
  • Expansion: Significant Phase 3 activity, approaching or pursuing approvals
  • Mature: Substantial Phase 4 post-marketing studies
  • Stable: Mixed phase distribution, steady development
  • Declining: Low active trial ratio, reduced R&D investment
