Study Details

Brief summary:

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.

  • 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.

Exclusion Criteria:

  • 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.
  • Patients with primary adrenocortical insufficiency or adrenocortical hyperfunction.
  • Rheumatoid arthritis, evidence or suspicion of infectious/septic arthritis, or other acute inflammatory arthritis.
  • Polyarticular gouty arthritis involving more than 4 joints.
  • Participation in another concurrent investigational study within 30 days of randomization or has taken an investigational drug within five times the half-life of that investigational drug has passed.
  • 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.
  • Pregnant or nursing (lactating) women. Women of childbearing age are required to be using an acceptable method of contraception.
  • Patients taking urate-lowering therapy had to be on a stable dose and regimen for ≥2 weeks before entering the study and remain on a stable dosage and regimen for at least 1 week after Purified Cortrophin® Gel.
  • Use of specified pain relief medications or biologics (including glucocorticoids, narcotics, paracetamol/acetaminophen, NSAIDs, colchicine, IL-blockers and tumor necrosis factor \[TNF\] inhibitors) within specified periods (see Appendix 5) prior to randomization.

  • Vaccination within 30 days prior to study enrollment and during the study period.
