Abstract

Objectives: Early treatment of individuals at risk of developing rheumatoid arthritis (RA-risk) in the preclinical phase has the potential to positively impact both patients and society by preventing disease onset and improving patients' quality of life. The PRAIRI study was a randomised, double-blind, placebo-controlled trial with the B-cell depleting agent rituximab (RTX), which resulted in a significant delay of arthritis development of up to 12 months in seropositive RA-risk individuals. Here, we report our findings on patient-reported outcomes (PROs) in this study population.

Methods: Seventy-eight RA-risk individuals were treated with one single dose of either placebo (PBO) or 1000 mg RTX plus 100 mg methylprednisolone (MP) and anti-histamines, regardless of treatment allocation, as co-medication. Data on quality of life were collected at baseline and 1, 4, 6, 12 and 24 months using established PRO questionnaires (visual analogue scale (VAS) pain, health assessment questionnaire disability index (HAQ-DI) score, EuroQol five dimension (EQ-5D) and both physical and mental component score of the 36-item short-form heath survey (SF-36)).

Results: No significant changes in quality of life over a 2 year follow-up were observed in at-risk individuals treated with RTX compared to PBO given the PRO scores at 24 months (mean difference±SEM: HAQ score=0.07±0.16; EQ-5D=-0.02±0.05; VAS pain=11.11±7.40). Furthermore, no significant effect of treatment on perceived arthritis severity at the time of clinically manifest disease (arthritis) was found.

Conclusion: One single dose of RTX plus MP administered to RA-risk individuals does not have a meaningful and measurable positive effect on PROs after 2 years of follow-up and/or perceived disease severity at the time of arthritis development.

PRO scores for health assessment questionnaire disability index (HAQ-DI) score, EuroQol five dimension (EQ-5D) questionnaire, visual analogue scale (VAS) pain, physical component score (PCS) and mental component score (MCS) of the 36-item short-form heath survey (SF-36) questionnaire, stratified for treatment (n placebo (PBO)=14; n rituximab (RTX)=12) at baseline and arthritis visit are shown for patients who developed rheumatoid arthritis (RA) within the study period. Median (IQR) time of RA onset was 12.0 (2.0–15.0) months in the PBO group and 16.5 (9.75–28.0) in the RTX group (PBO=red line; RTX=blue line).
