About
Multi-site, first-in-human study to assess safety and efficacy of an active implantable Vagus Nerve Stimulation (VNS) device in 15 adult patients with active moderate-to-severe rheumatoid arthritis who have had an incomplete response or intolerability to at least two different mechanisms of action.
Full description
This is a two-stage study where Stage 1 is open label, and Stage 2 is randomized and sham controlled where the sites and subjects are blinded to treatment. Three subjects will be enrolled in Stage 1 of the study. And 12 subjects will be enrolled in Stage 2. Subjects will be treated for a total of 12 weeks.
Subjects will be asked to visit the clinic at day 0, week 1-6, week 8 and week 12. During these visits, the following activities will be conducted: standard patient and physician assessments of RA activity, blood sample collection for RA biomarkers, and a hand MRI.
Subjects who complete the study will have the option to enroll in a long-term extension study. Subjects that do not participate in the extension study can opt to either have their device permanently inactivated and left in place or have the device surgically explanted.
