Celltrion USA announced that it has signed an agreement with Cigna Healthcare and Express Scripts, that will help expand patient access to ZYMFENTRA® (infliximab-dyyb), the first and only U.S. Food and Drug Administration (FDA)-approved subcutaneous infliximab. The agreement, effective August 1, 2024, lists ZYMFENTRA as the preferred medication on the Cigna's medical formulary serving 16.1 million insured lives. ZYMFENTRA was approved by the FDA in October 2023 for maintenance therapy in adults with moderately to severely active ulcerative colitis (UC) and Crohn's disease (CD) following treatment with an infliximab product administered intravenously.

This follows Celltrion USA's announcement in April 2024 that Express Scripts provided ZYMFENTRA Preferred Brand Access on the Express Scripts National Preferred Formulary.
