Phase 2 Study of Safety, Tolerability and Efficacy of Pirfenidone in Patients With Rheumatoid Arthritis Interstitial Lung Disease (TRAIL1)

The purpose of this study is to to assess the safety and tolerability of pirfenidone 2403
mg/day for the treatment of RA-associated 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 ≤100 and
% predicted DLCO ≥30 and ≤100 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.

of having ILD, or having clinical symptoms consistent with ILD (i.e., cough,
dyspnea), at least 6 months before randomization

on standardized equipment and centralized quality controlled):

1. % predicted FVC ≥ 40% and ≤ 100% at Screening

2. Change in pre- and post-bronchodilator FVC (measured in liters) between Screening
(Visit 1) and Visit 2 must be a <10% relative difference, calculated as shown

Screen FVC (L) - Day 1 FVC (L) × 100% Screen FVC (L)

3. %DLCO ≥30% and ≤ 100% at Screening, confirmed by central review

Informed Consent and Protocol Adherence:

6. Able to understand and sign a written informed consent form

7. Pregnancy or lactation. 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.

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.

Exclusion Criteria:

Disease-Related Exclusions:

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 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

toxicity, sarcoidosis, hypersensitivity pneumonitis, bronchiolitis obliterans
organizing pneumonia,

2. Medical history including Human Immunodeficiency Virus (HIV),

3. 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 < 0.7

lupus erythematosus)

principle investigator

Medical Exclusions:

10. Clinical evidence of active infection, including but not limited to bronchitis,
pneumonia, sinusitis, urinary tract infection, or cellulitis

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
