Purified Cortrophin® Gel Efficacy and Safety Study of 2 Dose Levels in Patients With Acute Gout Flares

Recruiting now · Phase 4

Conditions studied: Gout Arthritis, Gout Flare, Gout

In brief

This is a randomized, multicenter, double-blind, single administration study to investigate the efficacy and safety of 2 dosing regimens of Purified Cortrophin® Gel in the treatment of an acute gouty arthritis flare. The study consists of three periods: an optional pre-screening period, a double-blind treatment period, and a 7-day follow-up period. The treatment period is double-blind, and the patients will be randomized to treatment with 40 U Purified Cortrophin® Gel or 80 U Purified Cortrophin® Gel in a 1:1 ratio. Purified Cortrophin® Gel will be administered once (either subcutaneously or intramuscularly) on the first visit (Day 0; Visit 1) and surveyed after 24 hours (Day 1), 48 hours (Day 2), and 72 hours (Day 3; Visit 2) as well as on Day 7.

• History of ≥ 1 gout flares within the 12 months prior to study entry
• The patient meets at least one of the following criteria for both NSAIDs and colchicine treatment options:
• Minimum of one episode of being intolerant, or unresponsive to the treatment, see Appendices 2-4.
• The investigator deems the patient is either contraindicated or inappropriate for the treatment. Inappropriateness could be due to anticipated changes in patient status (i.e., such as worsening of comorbidities or use of concomitant medication), see Appendices 2-4.
• Patients must be willing and capable of using an electronic device (e.g., cellphone) and must have access to a cellphone to be able to complete surveys.

You may not qualify if…

• Patients with scleroderma, osteoporosis, active or recurrent bacterial, fungal or viral infections, ocular herpes simplex, recent surgery (within 2 weeks prior to randomization or have an unhealed operation wound(s)), history of or the presence of a peptic ulcer, uncontrolled congestive heart failure, uncontrolled hypertension, uncontrolled diabetes type 1 or 2, or sensitivity to proteins derived from porcine sources.

• Previous inclusion in this study.
• Presence of severe renal function impairment: estimated creatinine clearance <30 mL/min/1.73m2 (CKD stages 4 and 5).
• Uncontrolled clinically significant hematologic, CNS, hepatic, pulmonary, gastrointestinal, metabolic, or endocrine disease as deemed by the investigator.
• Presence of any medical or psychological condition or laboratory result that might create risk to the patients (or interfere with the patient's ability to comply with the protocol requirements, or to complete the study) in the opinion of the investigator.
• Prior or current treatment with any ACTH product.
