Efficacy, Radiographic and Laboratory Changes in Refractory Rheumatoid Arthritis Patients Treated With H.P. Acthar Gel

Phase 4
Conditions
Rheumatoid Arthritis
Interventions
Registration Number
NCT03082573
Lead Sponsor
Iraj Sabahi Research Inc.
Brief Summary

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.

Detailed Description

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.

Arm && Interventions
GroupInterventionDescription
Group AH.P. Acthar gelWill be receiving the same background medications and H.P. Acthar gel 40 units twice weekly for 12 weeks. Patients in group A, can be cross over to group B on week 13 if disease is uncontrolled for continuation until week 24. If their disease is under control then they will continue with the same dosage until week 24. If the disease is under control, then tapering the steroid dosage can be attempted at the principal investigation's discretion.
Group BH.P. Acthar gelWill be receiving the same background medications and H.P. Acthar gel 80 units twice weekly for 12 weeks. if the disease is not under control, will continue with same dosage until week 24. If the disease is under control, will be given the option to reduce the dosage to 40 units twice weekly only if patient is suffering from H.P. Acthar gel related adverse effects. If the disease is under control, then tapering the steroid dosage can be attempted at the principal investigation's discretion.
