A Randomized Controlled Study of the Safety and Efficacy of Neurostimulation Using a Vagus Nerve Stimulation Device in Patients With Rheumatoid Arthritis

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.

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.

Inclusion Criteria:

1. Male or female and 22-75 years of age, inclusive

2. Have provided informed consent

3. Have a diagnosis of adult-onset rheumatoid arthritis as defined by the 2010 ACR/EULAR
classification criteria (Aletaha, 2010)

4. Have moderately to severely active RA defined by at least 4/28 tender and 4/28 swollen
joints and CDAI score >10

5. Have been treated at approved doses with at least 2 biologic DMARDs and/or new
targeted synthetic DMARDs (e.g. JAK inhibition) for at least 3 months and either:

1. experienced insufficient efficacy or loss of efficacy

2. experienced intolerance of such treatment

6. Have had regular use of at least 1 conventional DMARDs for at least the 12 weeks prior
to study entry with a continuous, non-changing dose for at least 8 weeks prior to
screening visit

7. Women of childbearing potential must not be pregnant at the time of screening and must
agree to use a double barrier method of contraception throughout the study

Exclusion Criteria:

1. Have taken the following within the defined time period prior to screening visit:

i. Rituximab: 6 months ii. Infliximab, golimumab, adalimumab, certolizumab pegol,
tocilizumab: 60 days iii. Abatacept, etanercept, anakinra: 30 days iv. Tofacitinib: 30
days v. Investigational biologic agents: 6 months for depleting agents, 60 days for
others vi. Investigational small molecules: 5 times the pharmacokinetic half-life or
30 days, whichever is longer vii. Intra-articular corticosteroid injection: 30 days

2. Are currently receiving corticosteroids at doses greater than 10 mg per day of
prednisone (or equivalent) or have been receiving an unstable dosing regimen of
corticosteroids within 2 weeks of screening visit

3. Have started treatment with non-steroidal anti-inflammatory drugs (NSAIDs) or have
been receiving an unstable dosing regimen of NSAIDs within 2 weeks of screening visit

4. Documented significant psychiatric illness or substance abuse

5. Active infection requiring treatment with antibiotics

6. Uncontrolled hypertension

7. Uncontrolled diabetes

8. History of stroke

9. Known cardiac disease, including cardiomyopathy with ejection fraction <40%, recent
myocardial infarction or unstable angina, or heart failure with New York Heart
Association class III or IV symptoms

10. Known neurological syndromes

11. Known atherosclerotic disease including contralateral carotid artery

12. BMI <18.5 or >35

13. Any condition per the investigator's clinical judgment that precludes participation in
the study
