This study will examine the clinical response, cytokine expression and joint imaging after addition of Acthar Gel. The hypothesis is that H.P. Acthar Gel is both safe and effective for treatment of patients with refractory rheumatoid arthritis (RA) and has different mechanism of action than steroids and other DMARDs.

Rheumatoid arthritis (RA) is a systemic inflammatory disease which causes premature mortality, disability and compromised quality of life in the industrialized and developing world. The prevalence of RA is believed to range from 0.5-1.0% in the general population. Over the past half century, many studies have found mortality to be increased in patients with established RA in comparison with the general population. Despite available treatment options for RA, some patients still have disease that is refractory to treatment and cannot achieve remission.

H.P. Acthar gel (adrenocorticotropic hormone gel) received FDA approval for treatment of a variety of diseases, including RA in 1952. The proposed efficacy of H.P. Acthar gel has been attributed to its ability to induce production of endogenous steroids and to bind melanocortin receptors on lymphocytes and other cells to modulate immunologic responses. The present study will examine the clinical response, cytokine production and joint imaging after addition of H.P. Acthar gel to confirm the efficacy, confirm different mechanism of action in comparison to steroids and other DMARDs by looking for post treatment changes in cytokine expression.

Inclusion Criteria:

1. Patients with diagnosis of RA with incomplete or failure to treatment described as either A or B A: Failure to achieve remission or low disease activity within 3 to 6 months of treatment with combination of methotrexate or other DMARDs therapy with a biologic DMARD in maximally tolerated doses within the usual therapeutic range.

   B- A requirement, in addition to DMARDs and biologic DMARDs, for chronic glucocorticoid therapy in a dose of greater than about 5 to 7.5 mg/day of prednisone or equivalent to achieve or maintain remission or low disease activity after 3 to 6 months of treatment.

2. Fluent in reading and writing in English language.

3. ≥ 21 years of age at the time of participation.

Acthar gel including but not limited to any known history of scleroderma, osteoporosis, systemic fungal infections, ocular Herpes Simplex, recent administration of live or live attenuated vaccine (prior 6 months), recent surgery (prior 6 months), history of or the presence of a peptic ulcer, primary adrenocortical insufficiency, adrenal cortical hyperfunction; congestive heart failure (defined as New York Hear Association Functional Class I to IV, uncontrolled hypertension.
3. Previous use of ACTH preparations for treatment of nephrotic syndrome (including but not limited to H.P. Acthar gel and Synacthen®).
