Clinical Trials in the Spotlight Main Page

The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) supports a range of clinical trials studying new and existing interventions for prevention and treatment of arthritis, musculoskeletal, and skin diseases.  Investigators supported by the NIAMS need your help finding individuals to participate in clinical trials.  Participating in clinical trials allows you to play an active role as a volunteer in research and contribute to generating new knowledge about the disease/condition, and potentially future treatments.  The information below is designed to help you quickly learn about actively recruiting research studies for which you or someone you know may be eligible. 

Study Description

Trisomy 21 (T21) causes a different disease spectrum in people with Down syndrome (DS), protecting these individuals from some diseases, while strongly predisposing them to others. For example, >50% of adults with T21 are affected by one or more autoimmune conditions, including a wide range of immune skin conditions. Unfortunately, the mechanisms driving this different disease spectrum are poorly understood, which creates a challenge in the clinical management of DS. The study team recently discovered that T21 causes consistent activation of the interferon (IFN) response across diverse cell types, which is likely due to the fact that four of the six IFN receptors are encoded on chr21.  The study team hypothesizes that hyperactivation of IFN signaling drives immune dysregulation and various pathologies in DS, and that pharmacological inhibition of IFN signaling could have multidimensional therapeutic benefits in this population. Accordingly, this study proposes to complete a first-in-kind clinical trial for a JAK inhibitor in DS.

Specific Aims are: 1. To define the safety profile of JAK inhibition in people with Down syndrome.  2. To determine the impact of JAK inhibition on the immune dysregulation caused by trisomy 21. 3. To define the impact of JAK inhibition on immune skin conditions in Down syndrome.  4. To characterize the impact of JAK inhibition on cognition and quality of life in Down syndrome.
