Inclusion Criteria

1. Clinical symptoms consistent with IPF, including the insidious onset of otherwise unexplained dyspnea on exertion, of =3 months duration
2. Diagnosis of IPF, defined as first instance in which a patient was informed of having IPF, within 48 months of randomization
3. Age 40 through 80 years, inclusive
4. High-resolution computed tomographic (HRCT) scan showing a pattern of disease consistent with a confident (definite) radiographic diagnosis of usual interstitial pneumonia (UIP)/IPF. For patients with surgical lung biopsy showing definite or probable UIP, the HRCT criterion of probable (UIP)/IPF is sufficient.
5. For patients aged <50 years: open or video-assisted thoracoscopic (VATS) lung biopsy showing definite or probable UIP within 48 months of randomization. In addition, there are no features supporting an alternative diagnosis on transbronchial biopsy or bronchoalveolar lavage (BAL), if performed (see Table 3–1).
6. For patients aged more/equal to 50 years: At least one of the following diagnostic findings, as well as the absence of any features on specimens resulting from any of these procedures that support an alternative diagnosis, within 48 months of randomization (see Table 3–1):
a. Open or VATS lung biopsy showing definite or probable UIP (see Appendix C of protocol)
b. Transbronchial biopsy showing no features to support an alternative diagnosis. These alternative diagnoses include but are not limited to granulomatous disease, sarcoidosis, and hypersensitivity pneumonitis.
c. BAL showing no features to support an alternative diagnosis

7. Percent predicted FVC =50% at the Screen Visit and Day 1 (before randomisation). The change in FVC (measured in liters) between the Screen Visit and Day 1 must be =10% relative difference
8. Hemoglobin (Hb)-corrected carbon monoxide diffusing capacity/carbon monoxide transfer capacity (DLco) =35% of predicted value at the Screen Visit only
9. Either FVC or Hb-corrected DLco less/equivalent to 90% of predicted value at the Screen Visit
10. No evidence of improvement in measures of IPF disease severity over the preceding year
11. Distance walked =150 meters (492 feet) with O2 saturation =83% on less/equal to 6 L/min of O2 during the 6-Minute Walk Test (6MWT) oxygen titration procedure performed during screening (see Study Reference Guide).
12. Able to understand and sign a written informed consent form
13. Able to understand the importance of adherence to study treatment and the study protocol, including the concomitant medication restrictions th

Exclusion Criteria

1.Not a suitable candidate for enrolment or unlikely to comply with the requirements of this study
2.Premature withdrawal from a randomized IPF clinical trial in the previous 2 years for any reason other than Sponsor decision or current participation in a clinical drug trial
3.FEV in the first second (FEV1)/FVC ratio <0.7 after administration of bronchodilator at the Screen Visit and Day 1 before randomisation
4.Bronchodilator Response defined by an absolute increase of =12% and an increase of 200 mL in the predicted FEV1 or FVC or both after bronchodilator use compared to the values seen before bronchodilator at the Screen Visit and Day 1 before randomisation
5 RV >120% of predicted (before administration of bronchodilator)
6.History of clinically significant environmental exposure known to cause PF (including drugs, asbestos, beryllium, radiation, domestic birds)
7.Known explanation for interstitial lung disease
8.Diagnosis of any connective tissue disease including scleroderma, systemic lupus erythematosus, and rheumatoid arthritis
9.Clinical evidence of active infection, including bronchitis, pneumonia, sinusitis, urinary tract infection, or cellulitis
10.In the clinical opinion of the investigator, the patient is expected to need and be eligible for a lung transplant within 72 weeks after randomisation.
11.Unable to undergo pulmonary function testing, which includes meeting the following reproducibility standards: At Screening, the 2 highest acceptable FVC values must be within 0.10 liter; At Day 1 the 2 highest acceptable FVC values must be within 0.10 liter; At Screening 2 of the 3 acceptable DLco values must be within 2 units (for TLco, within 0.67 SI units) of each other.
12.Any history of malignancy likely to result in death or significant disability or likely to require significant medical or surgical intervention within the next 2 years. This does not include minor surgical procedures for localized carcinoma (e.g., basal cell carcinoma)
13.Any condition other than IPF which, in the opinion of the investigator, is likely to result in the death of the patient within the next 2 years
14.History of advanced cirrhosis or clinically significant liver disease
15.History of unstable or deteriorating cardiac or pulmonary disease (other than IPF) within the previous 6 months, including: Myocardial infarction, unstable angina pectoris, coronary artery bypass surgery, or coronary angioplasty; Congestive heart failure requiring hospitalization; Uncontrolled arrhythmias; Asthma or chronic bronchitis requiring hospitalization in the last 6 months
16.Any condition, which, in the opinion of the investigator, might be significantly exacerbated by the known side effects associated with the administration of pirfenidone
17.Poorly controlled diabetes (defined by glycosylated hemoglobin [HbA1C] >10)
18.Pregnancy or lactation. Women of childbearing capacity are required to have a negative serum pregnancy test before treatment and must agree to maintain highly effective methods of contraception by practicing abstinence or by using at least two methods of birth control from the date of consent through the end of the study. If abstinence is not practiced then one o
