Core Tip

Core Tip: Infliximab maintenance therapy significantly reduced disease severity, improved quality of life, and reduced outpatient clinic visits and hospitalization related to active disease in Chinese patients with moderate to severe Crohn’s disease. Even though the drug acquisition costs of infliximab could not be fully offset by the saved medical costs, the cost-effectiveness of infliximab maintenance therapy was highly attractive from the perspective of Chinese health care payers.
