简要总结
The purpose of this pilot study is to investigate the safety and efficacy of etanercept (Enbrel™; Amgen) for the treatment of an acute gout attack will be non-inferior to triamcinolone acetonide an FDA approved drug to treat acute gout attacks.
详细描述
The study was designed as a 14-day, two center- pilot randomized, active-controlled, double-blind, study. The study was approved by the Institutional Review Board (IRB) Pro2018000562. Patients were screened for eligibility at the time of an acute flare. Patients aged 28-55 years with an acute gout flare meeting the validated definition of flare were enrolled (12). Onset of current acute gout flare was within 3 days prior to randomization and baseline pain intensity ≥50 mm on a 0-100 mm visual analogue scale (VAS), Gout patients were defined by a confirmed diagnosis of crystal proven gout and or a score of ≥ 8 on the 2015 American College of Rheumatology (ACR)/ European League Against Rheumatism (EULAR) Gout Classification Criteria (13).
Patients recorded pain intensity in the most affected joint prior to treatment. Efficacy, including pain on a 0-100 mm VAS, and safety assessments were conducted at 24 and 72 hours, 7 and 14 days after baseline.
