Description of intervention(s) / exposure
Drug: Inhaled Pirfenidone: Each patient will be randomized to either 50 mg inhaled pirfenidone taken once per day or 100 mg inhaled pirfenidone taken twice per day for 72 weeks, using the eFlow nebulizer.
Drug: Salbutamol: Patients who experience cough that limits their ability to complete dosing will administer 1 - 2 puffs (90 - 100 microgram (µg)) of salbutamol using a metered dose inhaler in order to complete the in-clinic dose. These patients, as well as patients with a history of asthma or smoking history of 20 pack years or greater, or patients that have a greater than or equal to 15% drop in FEV1 percent predicted in their pre-dose and post-dose readings will be required to administer 1 - 2 puffs (90 - 100 µg) of salbutamol using a metered dose inhaler prior to dosing throughout the study unless these patients are currently taking a long-acting beta-2-agonist therapy.
Patients will be trained to use the nebulizer at the first treatment visit. The first treatment will be overseen by clinic personnel. Compliance and tolerability to study drug will be assessed during a telephone call one week after the first dose, as well as at monthly visits during the first 24 weeks. During Part B of the study (Week 25 - Week 72), compliance and tolerability will be assessed during a monthly phone call, as well as at clinic visits every 3 months. Overall study drug compliance will be assessed by calculating the amount of vials used at each clinic visit.

Outcomes
Primary outcome [1] 307999 0
The primary objective is to evaluate safety and tolerability of treatment with AP01 by monitoring AEs and post-dose spirometry.
Adverse events will be assessed during scheduled phone calls to the patients and at clinic visits. Adverse events will be recorded in the electronic CRFs. In the AP01-001 single ascending dose study, the drug was well tolerated in both normal volunteers and IPF patients. The most commonly reported event was cough, which was noted in 7 of 38 volunteers and 1 of 6 IPF patients in the Phase 1 study. Cough was mild, self-limited, and did not prevent the full administration of aerosol dose in any subject. No serious adverse events were reported in the study and all subjects completed the trial.

Change from pre dose FVC % predicted as measured by spirometry. A drop of greater than or equal to 15% from the pre-first dose FEV1 value accompanied by clinical symptoms will be considered a bronchospasm.

Eligibility
Key inclusion criteria
Population
1. Male and female patients, at least 40 years of age at Screening

7. FVC % predicted greater than or equal to 40% and less than or equal to 90% at Screening based on Global Lung Initiative equations. The first 20 patients randomized must have FVC greater than or equal to 50% predicted. After the first 20 patients have randomized, patients with FVC greater than 40% and less than 50% predicted at Screening will be allowed to be randomized in the study but randomization for these patients will be capped at 20 patients

9. DLCO greater than or equal to 30% and less than or equal to 90% at Screening
10. In the investigator’s opinion, no evidence of improvement in measure of IPF disease severity over the preceding year
11. FEV1/FVC greater than or equal to 70%
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 and willing to follow all study requirements, including the concomitant medication restrictions, throughout the study
