ACR response rates were higher with ACTEMRA/RoACTEMRA versus placebo, regardless of the background DMARDs selected
- Compared with controls treated with placebo plus DMARDs, patients in the ACTEMRA/RoACTEMRA 8 mg/kg plus DMARDs arm had superior ACR20, 50 and 70 responses (p<0.0001 for each), and more patients achieved DAS28 remission at 24 weeks (p<0.0001).
- As early as Week 2, 64% of patients in the ACTEMRA/RoACTEMRA group had achieved a good or moderate EULAR response, compared with 18% of the control group (p<0.0001).

- Notably, ACTEMRA/RoACTEMRA in combination with any of the study DMARDs resulted in a higher proportion of ACR20 responders than did placebo plus DMARDs.
- Differences in response rates were apparent even when two background DMARDs were used (a subgroup of 234 patients), with 66% of patients in the ACTEMRA/RoACTEMRA group achieving an ACR20 response at Week 24, compared with 29% in the placebo group.

- ACTEMRA plus MTX reduced systemic inflammation and reversed chronic anaemia in patients with RA.
- CRP levels were normalised in patients in the ACTEMRA/RoACTEMRA 8 mg/kg plus DMARDs arm within 2 weeks of the first infusion and remained low throughout the study.
- By Week 24, there was a significant increase from baseline in mean haemoglobin levels in those treated with ACTEMRA/RoACTEMRA; in contrast, there was essentially no change in haemoglobin levels in those who received placebo.
- Patients in the ACTEMRA/RoACTEMRA 8 mg/kg arm also showed significant improvements in physical function (measured by HAQ-DI score) and fatigue (measured by FACIT-Fatigue score).
- In addition, mean improvements from baseline in SF-36 scores were higher in the ACTEMRA/RoACTEMRA group than in the control group at Week 24 for both physical and mental components (p<0.0001 for both).
