Lengthening Adalimumab Dosing Interval in Quiescent Crohn's Disease Patients

Oct 14th, 2022 - Rationale Adalimumab is both an effective induction and maintenance therapy for Crohn's disease (CD). Due to the risk of side effects (infections, injection reaction) and high costs, an extension of the injection interval is an attractive option. However, this strategy has not been evaluated yet in a randomized controlled trial in CD patients. Objective To assess non-inferiority and cost-effect...

Natural History Study of GATA2 Deficiency and Related Disorders

Oct 14th, 2022 - Mutations in GATA2, a critical hematopoietic transcription factor, underlie a complex congenital disorder characterized by immunodeficiency, bone marrow failure, and lymphatic/vascular dysfunction.
