Brief Summary
The objective is this study is to test whether use of Acthar gel in the context of sarcoidosis will lead to improved symptoms and lung function and correlate with decreased levels of predictive blood biomarkers, like chemokine ligand 9 (CXCL9).

Outcome Measures
Primary Outcomes (1)
Number of Participants That Show a Decrease in Blood CXCL9 Levels by 50%
Quantitative polymerase chain reaction assay was used to measure the gene expression for the gene CXCL9 using whole blood samples. The change in cycle threshold from before starting medication to the end of treatment was calculated. From this calculation, the number of participants that met the criteria of a 50% or greater drop in CXCL9 levels is reported.
within 6 months
Secondary Outcomes (2)
Participants With Improvement in Forced Vital Capacity (FVC) Liters by 5 Percent or More
within six months
Participants With Improvement in Dyspnea Score
within 6 months
Study Arms (1)
Acthar gel
EXPERIMENTALAfter a 4-week period of baseline monitoring, Acthar gel will be administered by intramuscular or subcutaneous injection. Initial dosing will be 40 U every 72 hours (or twice per week) for 4 weeks. Dosage will then be increased to 80 U with similar frequency for 8 weeks and up to 16 weeks.
