Summary

Pulmonary abnormalities are present in up to 60% of patients with early rheumatoid arthritis (RA), and up to 10% of the patients will develop clinical interstitial lung disease (ILD). Recent data indicate that inhibition of Janus kinase is beneficial for this extra-articular manifestation. Our goal is to determine whether tofacitinib is an effective and safe treatment, compared to standard-of-care methotrexate, for subclinical and clinical ILD in patients with early RA. The study also explores disease mechanisms in lungs and joints, to identify potential biomarkers for diagnosis, prognosis, and response to treatment of RA-ILD.

Detailed description

Study objectives: Primary objective: Effects of tofacitinib compared to that of methotrexate on interstitial pulmonary abnormalities at 24 weeks. Secondary objectives: Effects of tofacitinib compared to that of methotrexate on pulmonary abnormalities and function, RA disease activity and remission rates and patient reported outcome measures at different time points. Frequency of adverse events. Exploratory objectives: Effects of tofacitinib compared to that of methotrexate on cellular and molecular activity profiles of clinical samples from joints and lungs. Study design: A randomized, actively controlled, open-label, assessor-blinded, multicenter 48 weeks phase IV trial. The study design includes an optional sub-study collecting tissue samples using ultrasound-guided synovial biopsies, bronchoalveolar lavage and Particles in Exhaled Air (PExA). Study population and intervention: Patients with early untreated RA with active and seropositive disease will be eligible for screening and the performance of high-resolution computed tomography (HRCT). Subjects with pulmonary abnormalities suggestive of RA-ILD will be randomized (1:1) to tofacitinib 5 mg BID (group 1) or standard-of-care methotrexate 20 mg weekly (group 2) for 48 weeks. All patients receive prednisone with tapering for 6 weeks. Patients with incomplete response at 24 weeks will escalate to combination therapy with tofacitinib+methotrexate (group 3). Intra-articular injections of cortisone will be allowed during the study. 145 subjects will be included and screened (part 1), and approximately 48 subjects will be randomized to active treatment (part 2).

Type	Name	Description
DRUG	Tofacitinib	Open-label tofacitinib for 48 weeks. All subjects (both arms) receive prednisone starting at 20 mg QD with tapering for 6 weeks. Patients with incomplete response at 24 weeks will escalate to combination therapy with tofacitinib 5 mg BID + methotrexate 20 mg weekly up to week 48.
DRUG	Methotrexate	Open-label methotrexate for 48 weeks. All subjects (both arms) receive prednisone starting at 20 mg QD with tapering for 6 weeks. Patients with incomplete response at 24 weeks will escalate to combination therapy with tofacitinib 5 mg BID + methotrexate 20 mg weekly up to week 48.
