How RAPIVAB Works

Peramivir is an antiviral that acts as an inhibitor of influenza virus neuraminidase. By binding to and inhibiting this enzyme, the drug prevents the cleavage of sialic acid residues, which is necessary for the release of newly formed virions from infected cells. This action limits the spread of the virus within the respiratory tract.

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
