Brief summary
Systemic lupus erythematosus (SLE) is a chronic multi-system autoimmune disease impacting the physical, social, psychological health and quality of life of patients. Fatigue and pain are aspects of SLE patients which affect their health related quality of life (HRQOL). The purpose of this study is to determine the effect of milnacipran on fatigue in SLE patients with widespread pain (WSP) or fibromyalgia syndrome (FMS). A secondary objective will be to determine the effect of milnacipran on pain and quality of life measurements. Fifty SLE male and female patients, 18 years and older, will be recruited for a 15-week study, in which patients will be receive 14 weeks of milnacipran 50-100 mg twice a day or placebo. Measurements of fatigue, pain, and HRQOL will be compared between the milnacipran and placebo groups at the screening visit, baseline visit, week number 6, and week number 14. Milnacipran has been shown to be an effective treatment for pain, fatigue and physical function in FMS patients. To date, no clinical trials have demonstrated efficacy for the treatment of fatigue in SLE patients with concomitant WSP or FMS. The investigators hypothesize, based on FMS studies, that the milnacipran treated patients will have less fatigue than those in the placebo group. In addition, compared to control arm, those treated with the study drug will have less pain and improved quality of life.
Interventions
DRUGMilnacipran
After dose escalations, patients will receive Milnacipran administered at 50 mg twice a day after for 12 weeks or milnacipran 50 mg twice day for 4 weeks and then 100 mg twice a day for an additional 6 weeks depending on tolerability and fatigue response.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Fatigue | Baseline and Week 14 | A change in fatigue from baseline will be assessed with values obtained at week 14 using the Fatigue Severity Scale (FSS) in both the treatment and control groups. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Fatigue | Baseline and Week 6 | A change in fatigue will be assessed with values obtained at baseline and week 6 using the FSS and Visual Analogue Score (VAS) Fatigue. |
| Pain | Baseline, week 6 and week 14 | A change in pain will be assessed with values obtained at baseline, week 6, and 14 using the VAS Pain, and the Short Form - McGill Pain Questionnaire (SF-MPQ). |
| Health related quality of life | Baseline, week 6 and week 14 | Health related quality of life will be assessed with values obtained at baseline, week 6, and 14 using the Short form-36 (SF-36). |
| Overall health status | Baseline, week 6 and week 14 | A change in overall health status will be assessed using the Patient Global Impression of Change (PGIC) at baseline, week 6, and 14. |
