Alternative therapeutic options are needed for patients with systemic lupus erythematosus (SLE) not adequately controlled with or intolerant to traditional treatments. This study evaluated the efficacy of Acthar® Gel (ACTH_(1-39)) for reducing active SLE severity among patients receiving underlying conventional maintenance therapies.

Ten females (mean age = 49 yrs, disease duration = 7 yrs, Systemic Lupus Erythematosus Disease Activity Index-2000 [SLEDAI-2 K] = 10) currently on maintenance self-administered ACTH_(1–39) gel 1 mL (80 U/mL) for 7–15 days and were assessed weekly for 28 days. Outcome measures included Physician and Patient Global Assessments, SLEDAI-2 K, Lupus Quality of Life scale, Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-Fatigue) scale, erythrocyte sedimentation rate, and C-reactive protein. Student’s t-test compared data obtained at days 7, 14, and 28 with those from baseline.

The primary endpoint of SLEDAI-2 K improvement was reached at all observation times (p < 0.05) and statistically significant improvements were observed for most other parameters. No treatment-related serious or unexpected adverse events were observed.

The trial results reveal that among SLE patients in need of therapeutic alternatives, ACTH_(1-39) gel may provide significant disease activity reduction.
