About the “Blossom” Study

The AstraZeneca Blossom study is investigating anifrolumab for safety and efficacity in managing Systemic Lupus Erythematosus in pediatric patients from 5-18 years old.

Anifrolumab has been approved in the United States, Japan, Canada, European Union (EU), United Kingdom, and other countries for the treatment of adults with moderate to severe active SLE in combination with standard therapy.

Some parts of this study are experimental which means they have not been tested yet in pediatric patients.

What Should I Expect?

Screening Phase

Before you can start the anifrolumab or placebo you will undergo a series of tests. This is called screening. You will have one screening visit (if you weigh more than20 kg) or 2 screening visits (if you weigh 15 to ≤ 20 kg). Based on the results of the screening assessments, the study doctor will decide if you qualify to enter this study

Treatment Period

If you meet the screening criteria, you will be randomly assigned a study drug
(anifrolumab or placebo). You have a 3 in 4 chance of being given anifrolumab for the first year of the study (double-blind period). The placebo is a dummy substance with physical appearance identical to that of anifrolumab, but with no active ingredients. “Randomly assigned” means that whatever treatment you get will be by chance, like flipping a coin or drawing names out of a hat.

Open Label Period

During the second year (open label period) all participants will receive anifrolumab.

Follow Up Visit

For participants who qualify, they will have their information entered into a confidential database and be invited to participate in future visits.
