Effects of Tofacitinib vs Methotrexate on Rheumatoid Arthritis Interstitial Lung Disease

Study Purpose

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.

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years - 80 Years
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

1. Diagnosis of seropositive (i.e., presence of RF and/or anti-CCP antibodies) rheumatoid arthritis (RA) according to the ACR/EULAR 2010 criteria within 24 months. 2.

Active disease with ≥2 painful and ≥2 swollen joints in 66/68 joints and CRP ≥2.0 mg/L. 4. Aged 18-80 years. 5. The subject has given written consent to participate in the study.

Exclusion Criteria:

1. Current active inflammatory joint disease other than RA. 2.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT04311567
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	Phase 4

Additional Details

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).
