简要总结
People with Down syndrome (DS) display widespread immune dysregulation, including several immune skin conditions. This study hypothesizes that pharmacological inhibition of the increased interferon (IFN) signaling seen in DS is safe and could improve associated skin conditions.
The study evaluates the safety and efficacy treatment with Tofacitinib, an FDA-approved drug known to block IFN signaling, in adolescents and adults with DS and an autoimmune and/or autoinflammatory skin condition. Investigators will also measure the impact of interferon inhibition on a variety of molecular markers, as well as the cognitive abilities and quality of life of participants.
详细描述
Trisomy 21 (T21) is the most common human chromosomal disorder, occurring in ~1/700 live births, leading to the condition known as Down syndrome (DS). Importantly, people with DS display widespread immune dysregulation and over half of adults with T21 are affected by one or more autoimmune conditions, including several immune skin conditions. The driving hypothesis for this study is that hyperactivation of interferon (IFN) signaling leads to myriad immune-driven diseases and immunological phenotypes in people with DS, and that pharmacological inhibition of IFN signaling could have multidimensional therapeutic benefits in this population.
This study utilizes Tofacitinib, an FDA-approved drug known to block IFN signaling and several accompanying inflammatory pathways, to reduce IFN signaling in DS and to measure its effects via multidimensional endpoints. Previous studies and current clinical trials indicate that Janus kinase (JAK) inhibitors, such as Tofacitinib, can block inflammatory pathways and may have beneficial effects on immune skin conditions. Further, inhibition of chronically active IFN signaling in DS with Tofacitinib may attenuate other core drivers of immune dysregulation, leading to improvements in other immune diseases and conditions common to DS that are potentially driven by inflammation, such as cognitive deficits. Investigators will test these hypotheses using a battery of immune and molecular assessments, as well as cognitive testing and quality of life measures. This clinical trial evaluates adolescent and adult participants with DS during eight study visits over an approximate five month period.
Specific Aims:
- To define the safety profile of JAK inhibition in people with DS,
- To determine the impact of JAK inhibition on the immune dysregulation caused by trisomy 21,
- To define the impact of JAK inhibition on immune skin conditions in DS, and
- To characterize the impact of JAK inhibition on cognition and quality of life in DS.

Tofacitinib 5mg oral tablets twice daily for 16 weeks
干预措施: Tofacitinib (Drug)
结局指标
主要结局
Number of Serious Adverse Events (SAE) Definitely Related to Tofacitinib Treatment.
时间窗: Baseline to 16 weeks
Safety as measured by the number of serious adverse events definitely related to tofacitinib treatment.
Change in Whole Blood Transcriptome Interferon (IFN) Score
时间窗: Baseline and 16 weeks
The Interferon Score is a composite molecular measure used to quantify activation of the interferon signaling pathway. Interferon Scores are calculated by summing standardized expression (i.e. (expression value - mean) / standard deviation) of a predefined panel of 16 interferon-stimulated genes, measured by RNA-sequencing of whole blood samples. The resulting composite value provides an integrated measure of interferon pathway activity, with higher scores indicating greater pathway activation. No clinical relevance threshold has been established.
