In Part III maintenance of efficacy through Week 104 was demonstrated for each of the
JIA responses rates and were similar between the continuous ACTEMRA-treated
subgroup and the placebo-treated patients in Part II who re-commenced ACTEMRA. For
the continuous ACTEMRA group the JIA ACR30/50/70/90 response rates at Week 104
were 95.1%, 90.2%, 86.6% and 70.7%, respectively. For placebo-treated patients in Part
II who re-commenced ACTEMRA JIA ACR30/50/70/90 response rates at Week 104
were 95.1%, 95.1%, 91.4%, and 66.7%, respectively. Improvement in JIA ACR core
components observed at Week 40 was maintained.
Systemic Juvenile Idiopathic Arthritis
The efficacy of ACTEMRA for the treatment of active sJIA was assessed in a 12-week
randomised, double blind, placebo-controlled, parallel group, 2-arm study. Patients
(treated with or without MTX) were randomised (ACTEMRA: placebo = 2:1) to one of
two treatment groups. 75 patients received ACTEMRA infusions every two weeks either
8 mg/kg for patients ≥ 30kg or 12 mg/kg for patients < 30 kg and 37 patients were
assigned to receiving placebo infusions every two weeks. Corticosteroid tapering could
occur from week 6 for patients who achieved a JIA ACR70 response. After 12 weeks or
at the time of escape, due to disease worsening, patients were treated in the open-label
extension phase at weight appropriate dosing.
The demographic characteristics at baseline were similar between the placebo and
ACTEMRA groups. Patients were evenly split between male and female, with a median
age of 9 and 10 for the placebo and ACTEMRA groups, respectively. 27 patients in the
study were aged between 2-5 years, 48 patients between 6-12 years and 37 patients
between 13-18 years. Baseline disease characteristics studied included fever and rash
status, previous use of DMARDs, previous use of biologics, CRP, and articular and extraarticular
damage. All were similar between the placebo and ACTEMRA groups except
for a higher proportion of patients with rash in the placebo group (48.6%) compared with
the ACTEMRA group (29.3%). In addition, baseline CRP was lower in the placebo group
in comparison with the ACTEMRA group.
The primary endpoint was the proportion of patients with at least 30% improvement in
JIA ACR core set (JIA ACR30 response) at Week 12 and absence of fever (no
