If you/your child join this study, you will come to 18 study visits at Children's Hospital Colorado over the course of 15 months. All participants in this study will receive benralizumab, which is given as an injection once every 4 weeks. At these study visits we will do a brief physical exam and ask you questions about your health. We will use a needle in your arm to take a blood sample. We will also ask you to give a urine sample. We will do an ECG to see how your heart is beating. If needed, you may be paid back for costs like parking, travel, hotel, or meals while taking part in the study.

Who can Participate

You/your child may be able to join this study if you are between the ages of 6 and 17 years old and you weigh 33 pounds or more. You must also have been diagnosed with EGPA by a doctor. If you are interested in joining our study, we will do other tests to make sure you meet other requirements and that it is safe for you to join.
