Inclusion Criteria:

Part A:

- Male and female subjects >= 18 years at the time of signing the consent form.

Parts B and C :

- Male subjects >= 45 years and female subjects >= 55 years at the time of signing the consent form.

Part A:

• Healthy as determined by the investigator or medically qualified designee based on a medical evaluation including medical history, physical examination, laboratory tests, 12-lead ECG and pulmonary function tests.
• A subject with a potentially clinically significant abnormality or laboratory parameter(s) which is/are not specifically listed in the inclusion or exclusion criteria, outside the reference range for the population being studied may be included only if the investigator in consultation with the Medical Monitor if required agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures. Subjects with FEV1, FVC and DLCO values outside the normal range may be included only if the investigator in consultation with the Medical Monitor agree and document that the finding is unlikely to introduce additional risk factors and will not interfere with the study procedures.

Parts B and C:

• Subject is ambulant and capable of attending a PET scan visit as an outpatient.
• Subjects will have a diagnosis of IPF as determined by a responsible and experienced chest physician and based on established criteria defined by the American Thoracic Society/European Respiratory Society Internationale Multidisciplinary Consensus Classification of the Idiopathic Interstitial Pnuemonias.
• FVC > 50 % predicted and DLCO > 50% predicted. Following a review of the safety data at the interim, these criteria may be altered to FVC > 50% predicted and DLCO > 40% predicted.

Part A:

- Body weight >=50 Kilogram (kg) and BMI within the range 19.0 - 35.0 kg/meter square (m^2) (inclusive).

Parts B and C:

• Body weight >=45 kg and BMI within the range 18.0 - 35.0 kg/m^2 (inclusive)
• Female subjects are eligible to participate if they are of non-childbearing potential defined as premenopausal females with a documented tubal ligation or hysterectomy; or postmenopausal defined as 12 month of spontaneous amenorrhea (in questionable cases a blood sample with simultaneous follicle stimulating hormone (FSH) > 40 milli-international unit (MIU)/millilitre (ml) and estradiol > 141 picomole (pmol)/litre (l) is confirmatory (as a precaution a pregnancy test is conducted prior to dosing, a positive test leads to exclusion).
• Male subjects with female partners of child bearing potential must comply with the following contraception requirements from the time of first dose of study medication until 90 days after the last dose of study medication. a. Vasectomy with documentation of azoospermia b. Male condom plus partner use of one of the contraceptive options below: i. Contraceptive subdermal implant that meets the Standard Operating Procedure (SOP) effectiveness criteria including a <1% rate of failure per year, as stated in the product label ii. Intrauterine device or intrauterine system that meets the SOP effectiveness criteria including a <1% rate of failure per year, as stated in the product label iii. Oral Contraceptive, either combined or progestogen alone iv. Injectable progestogen v. Contraceptive vaginal ring vi. Percutaneous contraceptive patches This is an all-inclusive list of those methods that meet the following GlaxoSmithKline (GSK) definition of highly effective: having a failure rate of less than 1% per year when used consistently and correctly and, when applicable, in accordance with the product label. For non-product methods (e.g., male sterility), the investigator determines what is consistent and correct use. The investigator is responsible for ensuring that subjects understand how to properly use these methods of contraception.
• Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the consent form and in protocol

Exclusion Criteria:

• Alanine transaminase and bilirubin >1.5x5xupper limit of normal (ULN) (isolated bilirubin >1.5xULN is acceptable if bilirubin is fractionated and direct bilirubin <35%).
• Current or history of photosensitivity.
• Current or chronic history of liver disease, or known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome or asymptomatic gallstones)
• QT interval corrected for heart rate (QTc )> 450 millisecond (msec) or QTc > 480 msec in subjects with Bundle Branch Block
• Current upper or lower respiratory tract infection on admission to the clinical unit.

Parts B and C:

• History or suffers from claustrophobia or subject feels unable to lie flat and still on their back for a period of up to 2 hours in the PET/ CT scanner (note, one rest period will be allowed during the scan if required).
• Previous inclusion in a research and/or medical protocol involving nuclear medicine, PET or radiological investigations or occupational exposure resulting in radiation exposure greater than 10 millisievert (mSv) over the past 3 years or greater than 10 mSv in a single year including the proposed study. Clinical exposure from which the subject receives a direct benefit is not included in these calculations.
• Subjects with current IPF exacerbation, upper or lower respiratory tract infection.
• Subjects with severe co-existent chronic obstructive pulmonary disease (COPD), for example FEV1 < 60% predicted.

All Parts:

• Use of prohibited medication
• Subjects who are currently taking Pirfenidone or Nintedanib or who have received Pirfenidone or Nintedanib within the 30 days prior to the first dosing day will be excluded from the study.
• Subjects prescribed long-term continuous home oxygen therapy (those whose use of oxygen is intermittent and for symptom relief only are not excluded)
• History of alcohol consumption regularly in excess of: An average weekly intake of >21 units for males or >14 units for females. One unit is equivalent to 8 g of alcohol: a half-pint (~240 ml) of beer, 1 glass (125 ml) of wine or 1 (25 ml) measure of spirits.
• Urinary cotinine levels indicative of smoking or history or regular use of tobacco- or nicotine-containing products within 3 months prior to screening.
• History of sensitivity to heparin or heparin-induced thrombocytopenia.
• History of sensitivity to any of the study medications, or components thereof or a history of drug or other allergy that, in the opinion of the investigator or Medical Monitor, contraindicates their participation.
• Presence of hepatitis B surface antigen (HBsAg), positive hepatitis C antibody test result at screening or within 3 months prior to first dose of study treatment.
