- Must be able to communicate with site personnel and to understand and voluntarily sign the Informed Consent Form.Additional Inclusion Criterion for Cohort 5
- Current or past smokers with > 20 pack year history of smoking and decreased lung function (FEV1 >= 50% predicted)
- Diagnosis of IPF by American Thoracic Society (ATS) 2011 criteria
- Males or females 18 to 70 years

- Participation in a clinical study with administration of an investigational drug product within the previous 30 days, or five half-lives (T1/2) of the previously administered investigational product.
- Donation of blood or significant blood loss within the 8 weeks prior to admission to Phase 1 facility.
- Donation of plasma within the week prior to admission to Phase 1 facility.
- Any other condition which in the view of the Investigator is likely to interfere with the study or put the subject at risk.
- Pregnant or nursing.
- Use of any medication in the opinion of the Principal Investigator that that might interact with study medication or may lead to abnormal chemistry of hematology tests.
- Clinically significant abnormality in the opinion of the Principal Investigator in baseline hematology or chemistry tests.

Interventions
Drug: Inhaled Pirfenidone: Cohorts 1, 2 and 3, except those receiving placebo, will receive a single ascending dose, (25, 50, and 100 mg dose of pirfenidone, respectively). Cohorts 4 - 6, except those assigned to placebo in Cohort 5, will receive a single dose (25, 50,or 100 mg pirfenidone) of the maximum tolerated dose from the first three cohorts. Drug: Salbutamol: Cohorts 1-3: If forced expiratory volume in one second (FEV1) in two or more subjects in any ascending dose cohort falls by greater than 10% at 15 minutes, all subsequent subjects will be pretreated with salbutamol. Otherwise, Cohort 4 will not receive pretreatment with salbutamol; Cohort 5 and Cohort 6 subjects with chronic obstructive pulmonary disease (COPD) or with a smoking history will receive pretreatment with 2 puffs (200µg) of salbutamol metered dose inhaler device within 30 minutes to inhalation of study drug. Subjects will be trained to used the nebulizer upon admission to the Phase 1 facility. This single dose investigational product administration will be overseen by personnel at the Phase 1 facility.
