This is a 3-month double blinded randomized controlled study of transcutaneous electrical vagus nerve stimulation (tVNS) compared to a sham stimulation for the treatment of patients with active systemic lupus erythematosus (SLE).
Patients with SLE and active, non-organ-threatening disease are eligible to participate in this prospective randomized double blind trial of active or sham transcutaneous electrical vagus nerve stimulation (tVNS). Active tNVS is performed by the use of a transcutaneous electrical nerve stimulation (TENS) device with electrodes attached to an area of the external ear innervated by the auricular branch of the vagus nerve. The same protocol is followed in the sham tVNS arm, but the pads are placed on an area of the external ear that is devoid of vagus innervation.TENS is applied for 60 to 120 minutes daily as tolerated and participants keep a detailed log of their daily TENS sessions. Patients return to clinic at weeks 4, 8 and 12 for study related assessments.

Percentage of Participants on Active vs Sham tVNS With Improvement in SLE Disease Activity by the BILAG-based Combined Lupus Assessment (BICLA)
Achieving a BICLA response requires to meet all of the following parameters: 1. All British Isles Lupus Assessment Group (BILAG) A scores improving to B/C/D and all BILAG level B scores improving to C/D 2. No single new BILAG A \& not \>1 new BILAG B scores, no worsening of the baseline Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) total score AND no worsening in the Physician Global Assessment (PGA) (\<10% worsening from baseline) 3. No initiation of non-protocol treatments or premature study discontinuation The range of values for the above instruments are listed below, with higher scores indicating more active disease: BILAG: 0 to 96 SLEDAI: 0 to 105 PGA: 0-3
Time frame: 12 weeks
Percentage of Participants on Active vs Sham tVNS With Improvement in SLE Disease Activity by the Systemic Lupus Erythematosus Responder Index (SRI-4)
SRI requires meeting all of the following parameters: 1. ≥4-point reduction from baseline in the Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score 2. No single new British Isles Lupus Assessment Group (BILAG) A score \& not \>1 new BILAG B scores AND no worsening in the Physician Global Assessment (PGA) (\<10% worsening from baseline) 3. No initiation of non-protocol treatments or premature study discontinuation The range of values for the above instruments are listed below, with higher scores indicating more active disease: BILAG: 0 to 96 SLEDAI: 0 to 108 PGA: 0-3
Time frame: 12 weeks
Percentage of Participants on Active vs Sham tVNS With Improvement in Heart Rate Variability (HRV)
HRV is measured by time domain (RMSSD and pNN50) and frequency domain \[high frequency (HF), low to high frequency (LF/HF) ratio\] parameters.
Time frame: 12 weeks
