Clinical Trial Summary

The administration of Janus kinase (JAK) inhibitors as well as biological disease-modifying anti-rheumatic drugs has dramatically improved even the clinical outcomes in rheumatoid arthritis (RA) patients with inadequate response to methotrexate (MTX). Upadacitinib is a selective JAK1 inhibitor to be approved for use in RA. Nearly half of patients added JAK inhibitors including upadacitinib can achieve clinical remission in RA patients with inadequate response to MTX. As the next step, it is the great issue whether disease activity can be maintained in good condition even if MTX is discontinued after achieving clinical remission in patients treated with the combination of JAK inhibitors and MTX. Thus, it is desirable to investigate the maintenance of clinical non-relapse after discontinuation of MTX in RA patients with clinical remission during treatment with upadacitinib plus MTX. In this study, we will evaluate the proportion of patients who maintained nonclinical relapse after discontinuation of MTX in patients with RA who achieved clinical remission after treatment with upadacitinib plus MTX. We will also use musculoskeletal ultrasound (MSUS) assessments to determine whether discontinuation of MTX can be maintained nonclinical relapse in RA patients achieving clinical remission.

Intervention

Drug:
• upadacitinib 15mg/day
Patients will receive upadacitinib 15mg/day and continue to receive same doses of MTX until 24 weeks. If patients achieve a European League Against Rheumatism (EULAR) moderate response or a Disease Activity Score 28 (DAS28-CRP) =3.2 at 12 weeks, and a DAS28-CRP of <2.6 at 24 weeks, they will discontinue MTX, and continue upadacitinib until 48 weeks.
