📝 Editor’s Comment (Key Follow-up Checkpoint)

📌 Verification of Patient Dosing and Phase 3 Clinical Progress in Europe

This disclosure confirms that Celltrion has secured final Part 2 approval for its Phase 3 clinical trial plan for CT-P44 in Europe following its earlier Part 1 clearance. With full Part 2 regulatory approval in place, it is key to monitor the initiation of patient recruitment and first-patient dosing at European clinical sites. Tracking subject enrollment and execution of the planned 2-year R&D timeline confirms operational development progress. Clinical progress, patient enrollment milestones, and top-line data updates can be verified through future regulatory filings or upcoming periodic reports (Quarterly, Half-Yearly, or Annual Business Reports).
