Primary Outcome(s)

Main Objective: 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

Secondary Objective: 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

Timepoint(s) of evaluation of this end point: Week 16

Primary end point(s): Percentage of patients meeting the JIA ACR 30 response criteria at Week 16

Secondary Outcome(s)

Timepoint(s) of evaluation of this end point: Secondary outcomes will be assessed at each regular study visit (every 3 months)

Secondary end point(s): - Percentage of patients meeting the JIA ACR 30/50/70/90/100 response criteria
- Changes from baseline in each of the 6 individual components of the JIA ACR core set variables
- Change from baseline in Psoriasis Area and Severity Index (PASI) for JPsA patients with at least 3% Body Surface Area (BSA) at baseline
- Change from baseline in Leeds Enthesitis Index (LEI) for patients with enthesitis at baseline
- Proportion of patients with disease flare (flare defined as worsening of =30% from baseline in at
least 3 of the 6 JIA ACR core set criteria and an improvement of =30% in no more than 1 of the
criteria)
- Trough concentrations of ixekizumab in patients with JIA subtypes of ERA (including JoAS) and JPsA at Week 16
- Percentage of patients with anti-ixekizumab antibodies
- Adverse events (AEs) including serious adverse
events (SAEs)
- Safety parameters including but not limited to infections, injection site reactions, and laboratory
data including B-, T-cell, and natural killer (NK)- cell levels, white blood cell (WBC) count, red
blood cell (RBC) count, alanine aminotransferase (ALT), aspartate aminotransferase (AST)
