Etanercept in Kawasaki Disease

Brief Summary
The purpose of this study is to determine whether Etanercept (Enbrel) when used in conjunction with IVIG and aspirin, improves treatment response to IVIG in patients with Kawasaki Disease. Funding Source- FDA/OOPD
Brief Title
A Randomized, Double Blind, Placebo Controlled Study of Etanercept in Children With Kawasaki Disease
Detailed Description
Kawasaki Disease (KD) is a potentially life threatening acute vasculitis in children with a predilection for involvement of the coronary arteries. Aspirin and Intravenous gamma globulin (IVIG) are principally used for the treatment of the symptoms of Kawasaki Disease. Aspirin reduces inflammation and platelet formation, but has no effect in attenuating the development of coronary abnormalities. Although IVIG reduces inflammation and the prevalence of coronary artery abnormalities, it has a relatively high failure rate of 23-30%, warranting new treatment methods for Kawasaki Disease. We propose a placebo controlled double blinded randomized study to determine if etanercept 0.8 mg/kg subcutaneously (max 25 mg) given three times at weekly intervals starting at initial diagnosis is safe in this patient population and if it is a successful adjunct therapy with IVIG in reducing the incidence of persistent or recurrent fever.

A Randomized, Double Blind, Placebo Controlled Study of the Effects of Etanercept in Children Presenting With Kawasaki Disease
Primary Outcomes
Outcome Description
The primary outcome is the proportion of subjects who become refractory to IVIG. Subjects requiring 1 dose of IVIG are classified as responders and subjects requiring more than 1 dose are classified as IVIG refractory.
Outcome Measure
IVIG Refractory
Outcome Time Frame
42 days after initial dose

Secondary Outcomes
Outcome Description
The primary echocardiographic outcome will be the proportion of subjects with improvement defined as (20% change in coronary artery) from the worst findings during the acute study period (scheduled visits from admission to visit 4, including any unscheduled visits) to the primary study outcome time-point at visit 5 (visit 5). This calculation will be based on changes in absolute values and not z-scores as initially planned. Groups will be compared using a logistic model including a binary term for age \< versus \> 1 year. Two aspects of the echo findings will be considered:

* Maximum aneurysm size and
* Maximum measurements for left main coronary artery (LMCA), left anterior descending artery (LAD) and right coronary artery (RCA).
* Change in diameter of each coronary artery will be determined at standard measurement location or aneurysm with the latter taking precedent.
Outcome Time Frame
42 days after initial dose
Outcome Measure
Determine if Etanercept Treatment Alters the Rate of Coronary Artery Dilation and Disease (CAD) at 2 and 6 Weeks After Treatment in Patients With Dilated Coro
