E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Rheumatoid arthritis associated interstitial lung disease (RA-ILD) |
|
E.1.1.1 | Medical condition in easily understood language |
ILD is inflammation and scarring of the lung tissue. In the case of RA-ILD, the scarring is caused when the over-active immune system attacks the lungs causing scarring to build up over time. |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Respiratory Tract Diseases [C08] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
1.To assess the efficacy and safety of pirfenidone 2403 mg/day as compared to placebo in patients with rheumatoid arthritis-associated interstitial lung disease (RA-ILD).
|
|
E.2.2 | Secondary objectives of the trial |
1. To explore the role of peripheral blood biomarkers in predicting disease progression and survival in patients with RA-associated interstitial lung disease.
2. To explore a spectrum of validated questionnaires to assess disease specific patient reported outcomes including overall health, and perspectives on symptoms, performance and quality of life. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
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. 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. Clinical symptoms consistent with ILD (i.e., cough, dyspnea) 5. No features supporting an alternative diagnosis on transbronchial biopsy, or SLB, if performed prior to Screening 6. 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 Screening (Visit 1) and Baseline (Visit 2) must be a <10% relative difference, calculated as: 100% * [absolute value (Screening FVC – Baseline FVC) / Screening FVC] c. percent predicted DLCO ≥30% or TLCO at Screening d. Screening (Visit 1) Pre-bronchodilator (BD) and Post-BD spirometry meets ATS quality criteria as determined by a central reviewer. 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 either a site Investigator or the central reviewer.
7. Stable dose (at least three months at the time of Screening) of corticosteroids or any cytotoxic, immunosuppressive or cytokine-modulating, or receptor- antagonist agent prescribed for rheumatoid arthritis, including but not limited to azathioprine, cyclophosphamide, cyclosporine, etanercept, iloprost, infliximab, leukotriene antagonists, methotrexate, mycophenolate mofetil, tacrolimus, montelukast, tetrathiomolybdate, TNF-α inhibitors, rituximab, abatacept, tofacitintib, tociluzimab. 8. Able to understand and sign a written informed consent form 9. 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 weeks of treatment. 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. 10. 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 pirfenidone. b. Men must refrain from donating sperm during this same period.
