Session Title: RA – Treatments IV: New Therapies & Strategies (2008–2012)
Session Type: Abstract Session
Session Time: 5:00PM-5:50PM
Background/Purpose: We previously reported positive efficacy and safety results of olokizumab (OKZ), an interleukin-6-inhibitor, in patients with RA inadequately controlled by MTX (NCT02760368; CREDO-1) [Nasonov E.et al. Arthritis Rheumatol. 2019; 71 (suppl 10); E. Nasonov,et al. 2020; EULAR Abstracts THU0176]. Here we present the patient reported outcomes (PRO) of CREDO-1 study and assess the effect of OKZ treatment comparing to placebo (PBO) on quality of life, work productivity and fatigue in patients with moderate to severe RA who have previously failed MTX therapy.
Methods: We compared PRO between three groups 1) subcutaneous injections of OKZ 64 mg every 2 weeks (q2w), 2) OKZ 64 mg every 4 weeks (q4w) and 3) PBO every q2w.
PRO included change from baseline in: Health Assessment Questionnaire-Disability Index (HAQ-DI); Patient’s Global Assessment of Disease Activity (PtGA), Patient’s Assessment of Arthritis Pain (Pain), Short Form-36 (SF-36) Physical (PCS) and Mental (MCS) components; European Quality of Life- Five-Dimension Questionnaire (EQ-5D), Functional Assessment of Chronic Illness Therapy-Fatigue Scale (FACIT-F) and Work Productivity Survey-Rheumatoid Arthritis (WPS-RA).
Results: 428 patients were enrolled and 396 completed the study. All PRO baseline characteristics were comparable across treatment arms: mean (SD) PtGA was 69.5 (15.5); Pain was 68.6 (17.5); HAQ-DI was 1.7 (0.5); SF-36 PCS was 32.1 (6.5); SF-36 MCS was 42.3 (10.0); EQ-5D was 40.3 (20.0) and FACIT-F was 26.8 (8.7).
Treatment with OKZ 64 mg q2w and 64 mg q4w resulted in significant improvement in PRO measures (Table 1). Improvements in all PRO measures observed at week 12 were sustained over week 24.
Mean improvements in both OKZ groups for PtGA, Pain, HAQ-DI, SF-36 PCS and MCS, and FACIT-F surpassed defined MCIDs for these measures. There were clear differences between both OKZ treatment groups and placebo in all PRO measures, with the exception of some WPS measures where differences between groups were variable. There were statistically significant changes between OKZ treatment groups and placebo for change from baseline in HAQ; however, no formal statistical testing was done for other PRO measures. No notable differences in PRO measures were observed between the two dose regimens of OKZ.
- Treatment with OKZ over a 24-week period was associated with significant improvements in PRO in patients with moderate to severe RA.
- There were no discernible differences between the two regimens of OKZ from patient’s perspective.
