How SIVEXTRO Works

Tedizolid phosphate is a prodrug converted by phosphatases to tedizolid, the active moiety. Tedizolid exerts its antibacterial activity by binding to the 23S ribosomal RNA of the 50S subunit of the bacterial ribosome. This action inhibits bacterial protein synthesis by preventing the formation of the 70S initiation complex, which is essential for the translation process.

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
