• Subjects with no clinically significant impairment in oxygen saturation.
• Subject satisfied a medical examiner about their fitness to participate in the study.
• Subject provided written informed consent to participate in the study.
• Subject was available to complete the study (including all follow up visits).

Confirmed at Baseline / Prior to First Dose:

• Subject continued to meet all screening inclusion criteria.
• Subject with a negative urinary drugs of abuse screen (including alcohol) prior to dosing.

Exclusion Criteria

• A clinically significant illness or surgery within 8 weeks prior to the Day 1 dose of study medication.
• Significant medical history that, in the Investigator's opinion, may have adversely affected participation.
• History of allergy or significant adverse reaction to drugs similar to the investigational drug, to nicotine, or to cholinergic drugs or to any drugs with a similar chemical structure.
• History of hypersensitivity (anaphylaxis, angioedema) to any drug.
• Use of any drug known to induce or inhibit hepatic drug metabolism, within 30 days prior to the Day 1 dose of study medication.
• Use of medications known to prolong QT/QTc interval within 14 days prior to the Day 1 dose of study medication.
• Any clinically significant findings of physical examination or laboratory findings at screening.
• A clinically significant history of drug or alcohol abuse.
• Receipt of regular/over the counter medication within 14 days of the Day 1 dose of study medication that may have had an impact on the safety and objectives of the study (at the Investigator's discretion).
• Evidence of renal, hepatic, central nervous system, respiratory, cardiovascular or metabolic dysfunction.
• Inability to communicate well with the Investigator (i.e., language problem, poor mental development or impaired cerebral function).
• Participation in a New Chemical Entity clinical study within the previous 4 months or a marketed drug clinical study within the previous 3 months. (N.B. washout period between studies is defined as the period of time elapsed between the last dose of the previous study and the first dose of the next study).
• Donation of 450 mL or more blood within the previous 3 months.

Confirmed at Baseline / Prior to First Dose:

• Development of any exclusion criteria since screening.
• Receipt of any medication since screening that may have had an impact on the safety and objectives of the study (at the Investigator's discretion).

Part 2 Inclusion Criteria

• Male patient or female patient of non childbearing potential with IPF.
• Male patient willing to use a condom, if applicable (unless anatomically sterile or where abstaining from sexual intercourse was in line with the preferred and usual lifestyle of the patient) from the first dose until at least 3 months after receiving the last dose of IMP.
• Aged between 45 and 85 years of age.
• With a forced vital capacity (FVC) ≥ 45% predicted and forced expiratory volume in 1 second (FEV1)/FVC ratio ≥ 0.7.
• Oxygen saturation > 90% by pulse oximetry while breathing ambient air at rest.
• Diffusing capacity of lungs for carbon monoxide (DLCO) > 25%.
• Had adequate organ function and a clinical diagnosis consistent with IPF prior to screening (based on the American Thoracic Society, the European Respiratory Society, the Japanese Respiratory Society and the Latin American Thoracic Association (ATS/ERS/JRS/ALAT) consensus criteria. The diagnosis would ordinarily have been confirmed at a multidisciplinary team meeting where the high resolution computed tomography (HRCT) findings in particular would have been discussed with a radiologist with respiratory expertise.
• Able to undergo BAL.
• Provided written informed consent to participate in the study.
• Available to complete the study (including all follow up visits).
• Negative urinary drugs of abuse screen, determined within 28 days of the first dose of IMP (N.B. a positive alcohol result could have been repeated at the discretion of the Investigator).
• Negative human immunodeficiency virus (HIV) and hepatitis B surface antigen (Hep B) and hepatitis C virus antibody (Hep C) results.
• No clinically significant abnormalities in 12 lead ECG determined within 28 days of the first dose of IMP.

Confirmed at Baseline / Prior to First Dose:

• Patient continued to meet all screening inclusion criteria. Exclusion Criteria
• Any condition that made the patient at unacceptable risk for bronchoscopy.
• Active cigarette smoking (defined as smoking more than 3 cigarettes daily within the last 6 months).
• Presence of a significant co morbidity felt to limit life expectancy to less than 12 months.
• HRCT pattern showing emphysema more than the extent of fibrosis of the lung area conducted within 12 months of first dose.
• Evidence of renal, hepatic, central nervous system, or metabolic dysfunction.
• Evidence of poorly controlled diabetes mellitus (defined as a glycosylated haemoglobin (HbA1c) of > 59 mmol/mol (7.5%).

A current inhaled steroid dose of ≤ 1000 µg beclomethasone dipropionate equivalent per day was acceptable if the dose was anticipated to remain stable during the study.
• History of malignancy, including carcinoma during the preceding 5 years.
• History of, or current asthma.
• Participation in a clinical study of an unlicensed drug in the previous 4 months, or a marketed drug study within the previous 3 months. (N.B. washout period between studies defined as the period of time elapsed between the last dose of the previous study and the first dose of the next study).
