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

Clinical evidence of active infection, including but not limited to bronchitis, pneumonia, sinusitis, urinary tract infection, or cellulitis. The infection should be resolved per PI assessment prior to enrollment. Any use of antibiotics must be completed 4 2weeks prior to the screening visit. Note that prophylactic antibiotics are not contraindicated or exclusionary. 11. Any history of malignancy diagnosed within 5 years of screening, other than basal cell carcinoma of the skin, squamous cell carcinoma of the skin, or low grade cervical carcinoma in situ. 12. History of LFT abnormalities as outlined below, or imaging, laboratory or other clinical information suggesting liver dysfunction, advanced liver disease or cirrhosis. Evidence of hepatic impairment that in the opinion of the investigator could interfere with drug metabolism or increase the risk of the known hepatotoxicity of study drug. Any of the following liver function abnormalities: 1. Total bilirubin above the upper limit of normal (ULN), excluding patients with Gilbert's syndrome; 2. Aspartate or alanine aminotransferase (AST/SGOT or AST/SGPT) > 3 X ULN; 3. Alkaline phosphatase > 2.5 X ULN. 13. History of end-stage renal disease requiring dialysis. 14. History of unstable or deteriorating cardiac disease, or unstable cardiac arrhythmia or arrhythmia requiring modification of drug therapy, myocardial infarction within the previous year, heart failure requiring hospitalization. 15. Any condition that, in the opinion of the investigator, might be significantly exacerbated by the known side effects associated with the administration of pirfenidone. 16. History of alcohol or substance abuse in the past 2 years, at the time of screening. 17. Family or personal history of long QT syndrome. Laboratory Exclusions: 18. Any of the following test criteria above specified limits: 1. Estimated glomerular filtration rate < 57. 2. Electrocardiogram (ECG) with a QTc interval >500 msec at Screening. Medication Exclusions: 19. Prior use of pirfenidone or known hypersensitivity to any of the components of study treatment. 20. Use of any of the following therapies within 28 days before Screening and during participation in the study: 1. Investigational therapy, defined as any drug that has not been approved for marketing for any indication in the country of the participating site. 2. Potent inhibitors of CYP1A2 (e.g. fluvoxamine, enoxacin) 3. Sildenafil (daily use). Note: intermittent use for erectile dysfunction is allowed. 21. Introduction and/or modification of dose of corticosteroids or any cytotoxic, immunosuppressive, or cytokine modulating or receptor antagonist agent for the management of pulmonary manifestations of RA, within 3 months of screening, is an exclusion criterion, for enrollment, with the exception of dose modification of systemic corticosteroids that are maintained at or below 20 mg prednisone daily or the equivalent. 22. Any use of an approved anti-fibrotic medication. However, introduction and/or modification of dose of corticosteroids or any cytotoxic, immunosuppressive, or cytokine modulating or receptor antagonist agent for the management of extrapulmonary manifestations of RA is not an exclusion criterion for enrollment.
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.
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.

|Rheumatoid Arthritis Interstitial Lung Disease|
This is a phase 2, randomized, double blind, placebo controlled trial of pirfenidone for the treatment of RA associated interstitial lung disease. Approximately 270 subjects will be randomized to receive Pirfenidone 2403 mg per day or placebo in a 1:1 ratio. The primary outcome of this study is to assess the efficacy of pirfenidone 2403 mg/day versus placebo in patients with RA associated interstitial lung disease, as defined by progression free survival over the 52 weeks of treatment. Patients will receive blinded study treatment from the time of randomization until the Week 52 Visit. Eligible patients aged 18 to 85 years must meet 2010 ACR/EULAR criteria for RA (Aletaha, Neogi et al. 2010) as well as RA-associated ILD, as determined by imaging and, when available, lung biopsy. Patients will be required to have a % predicted FVC ≥40 and % predicted DLCO ≥30 at screening. The dose of study treatment will be titrated over 14 days. Patients will receive a telephone assessment at Weeks 1 and 2, and visit the clinic at Weeks 4, 8, 13, 19, 26, 39, and 52. Subjects will have a follow up phone call 28 days after completion of the study drug. Patients should complete a compliance diary between visits. If patients discontinue study treatment for any reason before the end of the study, they should continue with all scheduled study procedures through Week 52. If subjects are unable to complete the study visits as scheduled, all efforts should be made to complete an early termination visit. The primary outcome variable of this study will be progression free survival, defined as progression free from decline in FVC of 10% or greater during the 52 week study period.
