VOYDEYA (danicopan)

Complement Factor D Inhibitors Trial Activity: Declining 2 active trials
First-in-Class Orphan Drug Breakthrough Therapy
Immunology Approved 2024-03-29

VOYDEYA (danicopan) is a complement factor D inhibitor indicated as an add-on therapy to ravulizumab or eculizumab for the treatment of extravascular hemolysis (EVH) in adults with paroxysmal nocturnal hemoglobinuria (PNH). It is specifically intended for patients who require additional control over EVH while maintaining their existing treatment for intravascular hemolysis. The medication has not demonstrated effectiveness as a monotherapy and must be prescribed in combination with the specified terminal complement inhibitors.

How VOYDEYA Works

Danicopan functions by reversibly binding to complement Factor D to selectively inhibit the alternative complement pathway. This inhibition prevents the cleavage of complement Factor B, which is a necessary step in forming the C3 convertase enzyme and generating downstream effectors. By blocking this proximal part of the complement cascade, the drug controls the C3 fragment opsonization that facilitates extravascular hemolysis in patients with paroxysmal nocturnal hemoglobinuria. This mechanism allows for the targeted management of extravascular hemolysis while co-administered treatments maintain control over terminal pathway-mediated intravascular hemolysis.

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
