Treatment Outcome and Prognostic Factors for Rheumatoid Arthritis (RA) Patients With Interstitial Lung Disease (ILD)

Study Purpose

The objectives of this single center, prospective, non-interventional cohort is to understand patient characteristics, general treatment patterns, effectiveness/safety of conventional disease modifying antirheumatic drug (DMARD) and biologic DMARD treatments in rheumatoid arthritis patients with ILD in the real-world setting

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

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.

Trial Details

Trial ID:

This trial id was obtained from, 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.


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.

Additional Details

Primary objective : Comparison of prognosis between RA-ILD and RA-non ILD patients Secondary objectives 1. Identification of the prognostic factors or aggravation factors of ILD in RA-ILD patients 2. Identification of the association between ILD and autoantibody profiles in RA-ILD patients 3. Comparison of RA disease activity control between RA-ILD and RA-non ILD patients using disease activity score (DAS)28-erythrocyte sedimentation ratio (ESR), DAS28 C-reactive protein (CRP), simple disease activity index (SDAI) and clinical disease activity index (CDAI) 4. Comparison of biologic and non-biologic DMARD treatment response in RA-ILD patients using disease activity parameters The study population will be adult RA patients who have checked a chest computed tomography (CT) scan within 2 years of enrollment. No additional visits or laboratory tests will be done outside the routine clinical practice for RA-non ILD patients. For RA-ILD patients, high resolution computed tomography (HRCT), pulmonary function test (PFT) and 6-min walk test will be examined annually to identify the progression of ILD. Selection of medication including conventional DMARDs, biologic DMARDs, glucocorticoid, and inhaler, dosing and treatment duration are at the discretion of the investigator.
