Celltrion's CT-P13 SC Phase 3 Part 1 Approval Expires in Pediatric UC Due to Strategic Shift, Signaling Potential Pipeline Delay


  • Celltrion disclosed that the Part 1 approval for its global Phase 3 trial of CT-P13 SC subcutaneous formulation in pediatric patients with moderately to severely active ulcerative colitis, granted by the European Medicines Agency EMA, expired on June 18, 2026.
  • The expiration is due to the company's decision not to submit the Part 2 trial plan following a change in clinical development strategy; under EU Clinical Trial Regulation, Part 1 approval automatically expires if Part 2 is not applied within two years.
  • While this decision may cause short-term delays in expanding the pediatric indication, the company plans to finalize a new schedule after discussing trial design with regulators, limiting the long-term impact on pipeline value.
  • [AI Summary]Celltrion's change in clinical strategy for CT-P13 SC in pediatric ulcerative colitis led to the expiration of Part 1 approval. This creates a short-term pipeline delay but does not affect existing adult indications or product revenue; future trial design discussions will determine the impact on shareholder value.
