E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy of ixekizumab in children with JIA subtypes of ERA (including JoAS) and
JPsA based on the JIA American College of Rheumatology (ACR) 30 response |
|
E.2.2 | Secondary objectives of the trial |
1. To evaluate the efficacy of ixekizumab in children with JIA subtypes of ERA (including JoAS) and
JPsA based on the other clinical responses, disease activity and physical function measures
2. To evaluate the efficacy of adalimumab (reference arm) in children with JIA subtypes of ERA (including JoAS) and JPsA based on JIA ACR 30 and the other clinical responses, disease activity and
physical function measures
3. To characterize ixekizumab pharmacokinetics (PK) in children with JIA subtypes of ERA (including
JoAS) and JPsA
4. To evaluate the potential development of antiixekizumab antibodies and their impact on the
efficacy and safety of ixekizumab in children with JIA subtypes of ERA (including JoAS) and JPsA
5. Describe the safety of ixekizumab in patients with JIA subtypes of ERA (including JoAS) and JPsA |
