Clinical Trials

About Clinical Trials
Clinical trial participation is an individual, and important, decision. There are many advantages to participating in a trial, including care from medical teams experienced with the disease and the opportunity to try a new medication long before it is approved by the Food and Drug Administration to treat an indicated condition. If you choose to participate in a clinical trial, you have the right to understand fully what is expected of you, what the trial will involve and the potential risks to your health. You also have the right to withdraw your consent to participate at any time. For more resources about trial participation and informed consent, please see the resources available from the U.S. Department of Health and Human Services.

Please note: Trials that are recruiting patients with eosinophil-associated disease and a search engine that can help match you to an enrolling trial appear below.  Neither the list nor search engine results are considered exhaustive. The clinical trials listed here were verified as open and enrolling at the time the post was made, and are monitored periodically to ensure that the trial is still accepting participants. If a trial is no longer accepting patients, APFED may not be notified. If you find registration has closed for a trial that is still listed on this page, please notify mail@apfed.org.
