the apollo device in systemic sclerosis for the management of fatigue, raynaud phenomenon and quality of life

Conditions: Systemic Sclerosis (SSc)

Summary: the purpose of this study it to test the efficacy of a wearable device to improve symptom management and maximize qualify of life in systemic sclerosis (ssc) patients in a randomized trial. specifically, we will evaluate if the apollo neuro device may improve the two specific symptoms highest ranked by patients as affecting qualify of life (fatigue, raynaud phenomenon) as co-primary outcomes.

systemic sclerosis (ssc) is a multisystem autoimmune disease that is characterized by progressive vasculopathy, excessive fibrosis, and immune system activation. fatigue in ssc is common and greatly impacts quality of life: the prevalence of fatigue in ssc patients is significantly higher than the general population. raynaud phenomenon (rp) in ssc is not only the most common ssc manifestation, affecting nearly all but is often the earliest ssc symptom. ssc-rp is the highest ranked ssc-related symptom affecting quality of life, and is a major cause of ssc-related morbidity. there are currently no approved medications to treat rp, ssc-associated rp phenomenon or fatigue in ssc. thus, a non-pharmacologic intervention has the potential to provide ssc patients with a new treatment modality without common limiting side effects, and access. the apollo wearable provides transcutaneous vibratory stimulation, and can be worn on the wrist or ankle. goal: to recruit 160 ssc patient participants into this randomized, sham-device controlled clinical trial. patients will be randomized 1:1 to receive the apollo vs. sham wearable, which they will wear daily for 6 weeks. outcome measures focus on quality-of-life. .
