Discontinuation of Methotrexate in Rheumatoid Arthritis Patients Achieving Clinical Remission by Treatment With Upadacitinib Plus Methotrexate

Phase 3

Recruiting

• Conditions: Rheumatoid Arthritis; JAK Inhibitor; Biomarker; Musculoskeletal Ultrasound
• Interventions: Drug: upadacitinib 15mg/day

• Registration Number: NCT05121298
• Lead Sponsor: Atsushi Kawakami

Brief 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.

Secondary Outcome Measures

Name	Time	Method
achievement of DAS28-CRP <=3.2	at weeks 12, 24 and 36
changes in the DAS28-CRP value	from week 24 to weeks 36 and 48	Higher scores mean a more active RA.
changes in the clinical disease activity index (CDAI) value	from week 24 to weeks 36 and 48	Higher scores mean a more active of RA.
clinical relapse (DAS28-CRP >3.2) at week 48 in patients who achieve the DAS28-CRP <2.6 at week 24	at week 48
changes in the simplified disease activity index (SDAI) value	from week 24 to weeks 36 and 48	Higher scores mean a more active of RA.
changes in the total power Doppler (PD) score	from baseline to weeks 12, 24, 36, and 48	The minimum: 0, max: 66. Higher scores mean a more active RA.
change in van der Heijde-modified total Sharp score (vdH-mTSS)	from baseline to weeks 12, 24, 36 and 48	The minimum: 0, max: 3. Higher scores mean a more joint destruction and deformity.
achievement of DAS28-CRP <2.6	at weeks 12, 24, 36 and 48
achievement of SDAI <=3.3	at weeks 12, 24, 36 and 48
changes in the combined PD score	from week 24 to weeks 36 and 48	The minimum: 0, max: 66. Higher scores mean a more active RA.
change in vdH-mTSS	from week 24 to weeks 36 and 48	Higher scores mean a more joint destruction and deformity.
achievement of EULAR moderate response	at week 12
changes in the DAS28-ESR value	from week 24 to weeks 36 and 48	Higher scores mean a more active RA.
changes in the total grayscale (GS) score	from baseline to weeks 12, 24, 36, and 48	The minimum: 0, max: 66. Higher scores mean a more active RA.
achievement of CDAI <=2.8	at weeks 12, 24, 36 and 48
