KIDCARE (Kawasaki Disease Comparative Effectiveness Trial)

Study Purpose

Kawasaki disease (KD) is a self-limited illness that affects the heart blood vessels (coronary arteries) of infants and children and is now the most common cause of acquired heart disease in children. A mixture of proteins from human blood (Intravenous immunoglobulin, IVIG) is a treatment that reduces the rate of the major complication of the disease: a bulging of the wall of the coronary arteries called an aneurysm. However, 10-20% of children are resistant to this treatment and the fever returns. These children have the highest rates of aneurysm formation and thus should be treated aggressively. Unfortunately, there are no guidelines for the best secondary treatment for these resistant patients because the problem has never been adequately studied. Most physicians choose either a second infusion of IVIG or an engineered antibody called infliximab that inactivates a molecule that promotes inflammation. This trial will randomize (assign by chance like the flip of a coin) IVIG-resistant patients to receive either a second IVIG infusion or infliximab and the response to treatment will be compared to learn which treatment stops the fever the fastest. In addition, parents and caregivers will provide observations about their child's response to the different treatments.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	N/A - 17 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Eligible subjects will be as follows: 1.

4 weeks to 17 years of age, 2. fulfill the American Heart Association case definition for complete or incomplete KD, 3. have had fever (T ≥38°C) for 3 to 10 days prior to initial IVIG treatment, 4. have fever (T ≥38°C orally or rectally) between 36 hours and 7 days after end of the first IVIG infusion without other likely cause.

Exclusion Criteria:

1. Patient treated with infliximab or steroids for present illness (pts who received oral steroids as outpatients prior to KD diagnosis but who otherwise qualify for the study will not be excluded) 2. Known prior infection with tuberculosis, coccidiomycosis, or histoplasmosis.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT03065244
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 3

Additional Details

This is a 3-year (2.75-years of enrollment), Phase III, two-arm, randomized, multi-center, superiority treatment study to compare infliximab to a second intravenous immunoglobulin (IVIG) infusion for treatment of persistent or recrudescent fever in children with KD who fail to become afebrile after the first IVIG infusion. 1. Specific aim 1 will test the hypothesis that infliximab will be superior to a second intravenous immunoglobulin (IVIG) infusion for treatment of persistent or recrudescent fever in children with KD who fail to become afebrile after the first IVIG infusion (resistant KD). Cessation of fever (<38°C rectally or orally) within 24h of initiation of study treatment infusion will be the primary outcome measure. 2. Specific aim 2 will test the hypothesis that infliximab treatment will result in more rapid resolution of inflammation compared to second IVIG as measured by the change in white blood cell count (WBC), absolute neutrophil count (ANC), and high-sensitivity C-reactive protein (hsCRP) concentration between baseline and 24 hours and 2 weeks following study treatment. 3. Specific aim 3 will test the hypothesis that infliximab treatment will result in a reduction from baseline in coronary artery Zworst score of ≥ 0.05 standard deviation units as compared to second IVIG at 2 weeks following study treatment measured by echocardiography.
