Background: Olokizumab (OKZ) is an interleukin-6-inhibitor for treatment of Rheumatoid Arthritis (RA). In these analyses, we present patient reported outcomes (PROs) reported by MTX-IR patients with moderate to severely active RA treated with OKZ vs adalimumab (ADA) or placebo in a phase 3 randomized controlled trial (RCT) (ClinicalTrials.gov number, NCT02760407).


Objectives: To assess the effect of OKZ treatment compared with placebo and ADA in patient global assessment of disease activity (PtGA), pain, physical function (HAQ-DI), fatigue (FACIT-F) and health related quality of life (SF-36 physical (PCS) and mental (MCS) component summary and domain scores) and work participation (WPS-RA) at week 12.


Methods: 1648 patients receiving MTX were randomized to receive SQ injections: 1) OKZ 64 mg every 2 weeks (q2w, n=464), 2) OKZ 64 mg q4w (n=479), 3) ADA 40 mg q2w (n=462) and 4) placebo q2w (n=243). At week 14, non-responders: subjects without ≥ 20% improvements in both swollen and tender joint counts, added rescue medication (sulfasalazine and/or hydroxychloroquine) to study treatment. Between groups differences in least-squares mean (LSM) changes from baseline were analyzed.


Results: At week 12, treatment with both OKZ doses and ADA resulted in statistically greater LSM changes from baseline than placebo across all PROs, including 7 of 8 domains of SF-36 with exception of role emotional ( Table 1 and Figure 1 ). Reported work and household work impairments, days productivities were reduced by half and missed household work days because of arthritis were all improved (p<0.01) with OKZ and ADA treatment. PROs further improved to week 24 in the active treatment arms. Post hoc analyses demonstrated that a higher proportion of patients receiving both doses of OKZ as well as ADA reported improvements ≥ minimum clinically important differences vs placebo (p<0.01) across all PROs, indicating clinically meaningful benefits on an individual patient basis. Estimates of numbers needed to treat indicated that between 5 and 10 patients would need to be treated to achieve these benefits. More patients in both OKZ groups reported scores ≥ normative values in PtGA, HAQ-DI and SF-36 PCS scores; with ADA in PtGA and HAQ-DI.

Conclusion: Treatment with both doses of OKZ resulted in similar, statistically significant improvements across PROs vs placebo in MTX-IR patients with moderate to severely active RA, comparable to ADA, that were clinically meaningful.
