Brief summary
Systemic Lupus Erythematosus (SLE) is a chronic autoimmune, inflammatory disease and musculoskeletal pain is one of the most common symptoms. This study will investigate whether transcutaneous stimulation of the vagus nerve will decrease lupus musculoskeletal pain. This study will additionally investigate the biologic effects of vagus nerve stimulation on inflammation. It will be the first clinical study using one of the body's own pathways of modulating the immune system and inflammatory response, the cholinergic anti-inflammatory pathway, in SLE.
Interventions
Patients will receive transcutaneous stimulation of the auricular branch of the left vagus nerve for 5 minutes daily for 4 consecutive days. The device is a handheld electrical pulse generator and a pair of electrodes to be placed at the ear for stimulation. The specific target at the ear will be the auricular branch of the vagus nerve which innervates the skin of the ear canal. Electrodes will be placed near/at the entrance to the canal of the ear to provide stimulation to the auricular branch.
Patients will receive sham transcutaneous stimulation of the auricular branch of the left vagus nerve for 5 minutes daily for 4 consecutive days. Sham stimulation will be performed in the identical manner as true transcutaneous stimulation except that the patient will not receive electrical stimulation of the vagus nerve.

Active infection including hepatitis B or hepatitis C at baseline, 15. Any condition which, in the opinion of the investigator, would jeopardize the subject's safety following exposure to a study intervention, 16. Pregnancy or lactation, 17.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change in Musculoskeletal Pain From Baseline. | 5 days | Patients rate their musculoskeletal pain by making a mark on a 10cm anchored Visual Analog Scale where 0=no musculoskeletal pain and 10 =worst possible musculoskeletal pain. |
| Percentage of Subjects With Treatment Emergent Adverse Events. | 12 days | The percentage of participants with grade 2 or higher treatment emergent adverse events will be assessed using the NCI-CTAEversion4. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change in Musculoskeletal Pain From Baseline | 12 days | Patients rate their musculoskeletal pain by making a mark on a 10cm anchored Visual Analog Scale where 0=no musculoskeletal pain and 10 =worst possible musculoskeletal pain. |
| Fatigue | 5 days | Change from baseline fatigue will be measured using the FACIT F (Functional Assessment of Chronic Illness Therapy) questionnaire. The score ranges from 0 to 52, a higher score indicates less fatigue. |
| Tender Joint Reduction | 5 days | The percentage of tender joints reduced from baseline assessed by an investigator upon examining 68 potential tender joints. |
| Swollen Joint Count Reduction | 5 days | The percentage of swollen joints reduced from baseline assessed by an investigator upon examining 66 potential swollen joints. Data shown for seven taVNS and five SS subjects with swollen joints at baseline. |
| Physician Global Assessment of Disease Activity (PGA) | 5 days | Change in PGA from baseline, an anchored visual analog scale.ranging from 0 to 3 with higher scores signifying higher disease activity. |
| Patient Global Assessment of Disease (PtGA) | 5 days | Change in Patient Global Assessment of disease (PtGA) from baseline. This measure is a 10 cm visual analog scale (0-10); higher scores indicate a higher patient assessment of their disease activity. |
