Abstract

Background Tofacitinib is a novel, oral Janus kinase inhibitor for the treatment of rheumatoid arthritis (RA).

Objectives To compare the effects of twice daily (BID) tofacitinib 5 mg and 10 mg monotherapy versus methotrexate (MTX) on patient-reported outcomes (PROs) in the 24-month Phase 3, randomised, double-blind, parallel-group ORAL Start study (NCT01039688) in MTX-naïve patients. Results from a 12-month interim analysis have been presented previously [1,2] here we present the final analysis at 24 months.

Methods MTX-naïve patients with moderate-to-severe active RA were randomised 2:2:1 to receive tofacitinib 5 mg (n=373) or 10 mg BID (n=397), or MTX (n=186) titrated from 10 mg per week to 20 mg per week by Week 8. Secondary PRO endpoints included the mean change from baseline in: Patient Global Assessment of arthritis (PtGA; Visual Analogue Scale [VAS]), pain (VAS), physical function (Health Assessment Questionnaire-Disability Index; HAQ-DI), fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue Scale; FACIT-F), and health-related quality of life (HR-QoL; Short Form 36 version 2, acute; SF-36). Analyses used a linear mixed-effect model with baseline values as covariates in the full analysis set (all randomised patients who received ≥1 dose of study drug and had ≥1 post-baseline measurement). Least squares (LS) mean changes from baseline (±standard error [SE]) and proportions of patients reporting improvements ≥minimum clinically important differences (MCID; no imputation for missing data) in PROs at Month 24 are presented. P-values presented here are with no correction for type I error inflation.

Results A total of 658 patients completed the 24-month study (266, 286, and 106 in the tofacitinib 10 mg and 5 mg and MTX groups, respectively). Over 24 months, significantly (p<0.05) greater improvements from baseline were observed with both tofacitinib 5 and 10 mg BID compared with MTX across the PROs analysed, with the exception of the SF-36 mental component summary score, which was significant at Month 3 but not later (Table 1). Compared with MTX, significantly greater proportions of patients receiving tofacitinib 10 mg BID reported changes ≥MCID in all PROs at Month 3, and all PROs, except HAQ-DI, at Months 12 and 24 and FACIT-F at Month 12. Numerically more patients administered tofacitinib 5 mg BID reported changes ≥MCID across PROs versus MTX.

Conclusions In this Phase 3 trial in MTX-naïve patients with RA, tofacitinib 5 and 10 mg BID monotherapy significantly improved multiple PROs over 24 months compared with MTX.
