  • Locally advanced, unresectable (stage III) EGFR exon 19 deletions or exon 21 L858R mutation-positive NSCLC that has not progressed during or following platinum-based chemoradiation therapy
  • First-line treatment of adult patients with metastatic EGFR exon 19 deletions or exon 21 L858R mutation-positive NSCLC
  • First-line treatment of adult patients with locally advanced or metastatic EGFR exon 19 deletions or exon 21 L858R mutation-positive NSCLC, in combination with pemetrexed and platinum-based chemotherapy
  • Metastatic EGFR T790M mutation-positive NSCLC in patients whose disease has progressed on or after EGFR tyrosine kinase inhibitor therapy

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
