本研究的目的是评估Guselkumab在对Ustekinumab治疗失应答的克罗恩病(CD,一种导致肠道严重炎症的长期疾病)研究参与者中的效果。 Objectives of Study:
The purpose of this study is to evaluate how well guselkumab works in participants with Crohn’s disease (CD; a long-term condition causing severe inflammation of the intestinal tract) who no longer respond to treatment with ustekinumab.药物成份或治疗方案详述:
Description for medicine or protocol of treatment in
detail:
纳入标准:
