- **Maximum age:** 75 Years
- **Sex:** ALL
- **Healthy Volunteers:** No

```
Inclusion Criteria:

1. Diagnosis of systemic sclerosis-related (SSc) confirmed by the American College of Rheumatology classification criteria of systemic sclerosis (Masi 1980); duration of diagnosis less than (\<) 7 years
2. Diagnosis of SSc-ILD based on an high-resolution computed tomography (HRCT) scan
3. Screening forced vital capacity (FVC) greater than equal to (\>=) 50 percent (%) of the predicted value, and screening carbon monoxide diffusing capacity (DLCO) \>=40% of the predicted value
4. At study entry, the participant either was not taking SSc-ILD medication or was taking cyclophosphamide or mycophenolate

Exclusion Criteria:

1. Clinically significant pulmonary hypertension
2. Known underlying liver disease
3. Clinical evidence of significant aspiration or uncontrolled gastroesophageal reflux
4. History of clinically significant asthma or chronic obstructive pulmonary disease
5. Active infection
6. Diagnosis of another connective tissue disorder
7. Evidence of a malignancy that is likely to result in significant disability or require significant medical or surgical intervention

## Arms

- **Pirfenidone: 4-Week Titration Group** (EXPERIMENTAL) — Participants will receive one 267 milligrams (mg) oral pirfenidone capsule three times daily (TID) (801 mg per day \[mg/day\]) for 2 weeks followed by two 267 mg oral pirfenidone capsules TID (1602 mg/day) for 2 weeks (titration period) and then three 267 mg oral pirfenidone capsules TID (2403 mg/day) for 12 weeks maintenance period).
- **Pirfenidone: 2-Week Titration Group** (EXPERIMENTAL) — Participants will receive one 267 mg oral pirfenidone capsule TID (801 mg/day) for 1 week followed by two 267 mg oral pirfenidone capsules TID (1602 mg/day) for 1 week (titration period) and then three 267 mg oral pirfenidone capsules TID (2403 mg/day) for 14 weeks (maintenance period).

## Interventions

- **Pirfenidone** (DRUG) — Pirfenidone will be administered orally at a dose of 267 mg one oral capsule TID (801 mg/day) for 1 or 2 weeks followed by two 267 mg oral capsules TID (1602 mg/day) for 1 or 2 weeks (titration period) and then three 267 mg oral capsules TID (2403 mg/day) for 12 weeks (maintenance period).

## Primary Outcomes

- **Percentage of Participants With Treatment-Emergent Adverse Events (AEs)** _(time frame: From baseline up to 28 days after the last dose of study drug (last dose = Week 16))_ — Percentage of participants who had treatment-emergent AEs, defined as newly occurring or worsening after first dose. Relatedness to (study drug) was assessed by the investigator (Yes/No). Participants with multiple occurrences of an AE within a category were counted once within the category.
- **Percentage of Participants With Treatment-Emergent Serious Adverse Events (SAEs)** _(time frame: From baseline up to 28 days after the last dose of study drug (last dose = Week 16))_ — An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to 28 days after last dose that were absent before treatment or that worsened relative to pretreatment state.

## Secondary Outcomes

- **University of California at Los Angeles (UCLA) Scleroderma Clinical Trial Consortium (SCTC) Gastrointestinal Trial (GIT) Questionnaire Scale Scores** _(time frame: Baseline, Weeks 4, 8, 12, and 16)_
