Acthar Gel was studied in patients with advanced pulmonary sarcoidosis who were on a stable dose of ≥5 mg of prednisone for ≥3 months1
A prospective, single-blind, 24-week study of 18 patients with advanced pulmonary sarcoidosis who were receiving prednisone and experiencing deterioration of pulmonary disease1
- All patients met American Thoracic Society criteria for diagnosis of chronic pulmonary sarcoidosis
- All patients were on a stable dose of ≥5 mg prednisone for ≥3 months
- All patients experienced deterioration of pulmonary disease defined as decrease of 5% forced vital capacity (FVC) in the previous year
- Patients were excluded if they had received anti-TNF antibody (eg, infliximab, adalimumab) within 6 months or were receiving treatment for sarcoidosis-associated pulmonary hypertension
- Patients received a loading dose of Acthar Gel 80 U once daily for 10 days
- Patients experiencing adverse events were instructed to reduce the Acthar Gel dose by half
- At Week 2, patients were randomized 1:1 to receive either Acthar Gel 40 or 80 U twice weekly for 22 more weeks
Study Assessments1
Primary endpoint
- Reduction in prednisone dose evaluated at Weeks 7 and 24
Secondary endpoints
- History and physical exam, including spirometry and 6-minute walk testing (6MWT)
- Patient-reported questionnaires:
- Kings Sarcoidosis Questionnaire (KSQ)
- Saint George Respiratory Questionnaire (SGRQ)
- Fatigue Assessment Scale (FAS)
- Diffusion of lung carbon monoxide (DLCO)
- High-resolution computed tomography (HRCT) paired scans
- F-fluorodeoxyglucose positron emission tomography (FDG PET): highest standardized uptake value (SUV) for the thorax and for any other region

Study Limitations
The efficacy and safety results discussed may not be representative of the overall symptomatic sarcoidosis patient population. Patients may have been on multiple medications. The clinical outcomes for the patients discussed may not be solely attributable to Acthar Gel.
Patients saw a significant reduction in prednisone dose with Acthar Gel1
Treatment with Acthar Gel provided a reduction in prednisone dose within 7 weeks—and persisted for 24 weeks (n=16)
- When the effect of Acthar Gel at any dose was analyzed, there was a significant reduction in the prednisone dosage at 7 weeks (P=.0156) and 24 weeks (P=.0078) compared to the initial dosage of prednisone
- At Week 7, there was no significant difference in reduction of prednisone dosage for those receiving Acthar Gel 80 U (median 0 mg, range 0 to -20 mg) vs those receiving Acthar Gel 40 U (median -2.75 mg, range 0 to -12.5 mg, P>.05)
- There was no significant difference between the prednisone dose at 7 weeks vs 24 weeks, or between the 40- and 80-unit treatment groups
94% of patients (16 of 17) remained on Acthar Gel for the full 24 weeks of the study period
Safety Findings
- 1 withdrew during the initial loading period
- 8 patients complained of one or more of the following: jitteriness (n=6), headache (n=3), edema (n=2), and nausea (n=1)
- 5 stopped loading dose between days 7 and 9 due to toxicity but began the randomized phase
- 1 stopped treatment within 2 weeks because of toxicity in the randomized phase in the 40-U arm
- 7 reduced their dose by half (2 in the 40-U arm and 5 in the 80-U arm, P>.05)
- 8 complained of anxiety and fluid retention on the day of drug administration; many of these occurred during the daily loading doses
- Adverse events associated with Acthar Gel use were collected prospectively for all patients
- No significant differences in reported toxicity, including changes in moodiness, appetite, or bruising
- No significant change in weight during the 24-week study period
- Of the 6 patients who had elevated hemoglobin A1C levels at baseline, none of the values fell into the normal range by the end of 24 weeks
- There were no changes in the patients’ diabetic or hypertensive medications during the course of the study
