To assess the efficacy and safety of pirfenidone 2403 mg/day as compared to placebo in patients with RA-associated interstitial lung disease.
To explore the role of peripheral blood biomarkers in predicting disease progression and survival in patients with RA-associated interstitial lung disease.
To explore a spectrum of validated questionnaires to assess disease specific PROs including overall health, and perspectives on symptoms, performance and quality of life.
1. Age 18 through 85 years, inclusive, at Screening
2. Probable or definite diagnosis of RA according to revised 2010 ACR/EULAR criteria, without evidence or suspicion of an alternative diagnosis that may contribute to their interstitial lung disease.
3. Diagnosis of ILD
a. supported by clinically indicated HRCT, and when available, surgical lung biopsy (SLB), prior to Screening, and
b. defined as the first instance in which a patient was informed of having ILD, or having clinical symptoms consistent with ILD (i.e., cough, dyspnea), at least 6 months before Screening, and
c. presence of fibrotic abnormality affecting more than 10% of the lung parenchyma, with or without traction bronchiectasis or honeycombing, on Screening and confirmed by adjudicated HRCT prior to Baseline
4. No features supporting an alternative diagnosis on transbronchial biopsy, or SLB, if performed prior to Screening
5. Attainment of the following centralized spirometry criteria (based on local spirometry on standardized equipment and centralized quality controlled):
a. percent predicted FVC ≥ 40% at Screening
b. change in pre-bronchodilator FVC (measured in liters) between Visit 1 (Screening) and Visit 2 (Randomization) must be a <10% relative difference, calculated as:
100% * [absolute value (Visit 1 FVC – Visit 2 FVC) / Visit 1 FVC ]
c. percent predicted DLCO or TLCO ≥25% at Screening
d. Screening (Visit 1) pre-bronchodilator (BD) and Post-BD spirometry meets ATS quality criteria as determined by a central reviewer
e. Baseline (Visit 2) Pre-BD spirometry meets ATS quality criteria as determined by the site Investigator or the central reviewer
6. Able to understand and sign a written informed consent form.
7. For women of childbearing potential: agreement to remain abstinent (refrain from heterosexual intercourse) or use two adequate methods of contraception, including at least one method with a failure rate of <1% per year, during the 52 week treatment period and for at least 118 days after the last dose of study drug.
a. A woman is considered to be of childbearing potential if she is postmenarcheal, has not reached a postmenopausal state (≥ 12 continuous months of amenorrhea with no identified cause other than menopause), and has not undergone surgical sterilization (removal of ovaries and/or uterus).
b. Examples of contraceptive methods with a failure rate of <1% per year include bilateral tubal ligation, male sterilization, established and proper use of hormonal contraceptives that inhibit ovulation, hormone-releasing intrauterine devices, and copper intrauterine devices.
c. The reliability of sexual abstinence should be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the patient. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or postovulation methods) and withdrawal are not acceptable methods of contraception.
8. For men who are not surgically sterile: agreement to remain abstinent (refrain from heterosexual intercourse) or use contraceptive measures, and agreement to refrain from donating sperm, as defined below:
a. With female partners of childbearing potential, men must remain abstinent or use a condom plus an additional contraceptive method that together result in a failure rate of < 1% per year during the treatment period and for at least 118 days after the last dose of study drug.
b. Men must refrain from donating sperm during this same period.
1. Not a suitable candidate for enrollment or unlikely to comply with the requirements of this study, in the opinion of the investigator
2. Cigarette smoking or vaping within 3 months of Screening or unwilling to avoid tobacco products throughout the study
3. History of clinically significant environmental exposure known to cause pulmonary fibrosis (PF), including but not limited to drugs (such as amiodarone), asbestos, beryllium, radiation, and domestic birds
4. Concurrent presence of the following conditions:
a. Other interstitial lung disease, related to but not limited to radiation, drug toxicity, sarcoidosis, hypersensitivity pneumonitis, or bronchiolitis obliterans organizing pneumonia
b. Medical history of viral hepatitis (positive Hep A antibody in the absence of elevated liver enzymes is not an exclusion)
c. Medical history of viral hepatitis
5. Concurrent presence of other pleuropulmonary manifestations of RA, including but not limited to rheumatoid nodular disease of the lung, pleuritis/pleural thickening, and obliterative bronchiolitis
6. Post-bronchodilator FEV1/FVC < 0.65 at Screening
7. Presence of pleural effusion occupying more than 20% of the hemithorax on Screening HRCT
8. Clinical diagnosis of a second connective tissue disease or overlap syndrome
(including but not limited to scleroderma, Sjogren’s
polymyositis/dermatomyositis, systemic lupus erythematosus but excluding
9. Coexistent clinically significant COPD/emphysema or asthma in the opinion of the site principal investigator
10. 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 2 weeks 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, and/or low grade prostate cancer. Criteria for low grade prostate cancer:
- Patients with suspicion for prostate cancer based on PSA and/or DRE should have been evaluated by urology
