Inclusion criteria:

Any patients diagnosed with IPF and who comply with eligibility requirements may qualify for participation in the trial.

• Currently treated with pirfenidone at full dose (this is only for patients going into Group 2).

Exclusion criteria:

• Total bilirubin >1.5 fold ULN at visit 1.
• Underlying chronic liver disease (Child Pugh A, B, or C hepatic impairment)
• Relevant airways obstruction (i.e. pre-bronchodilator Forced Expiratory Volume in 1 second (FEV1)/FVC <0.7 at visit 1).
• History of myocardial infarction within 6 months of visit 1 or unstable angina within 1 month of visit 1.
• Bleeding Risk:
• Known genetic predisposition to bleeding
• Patients who require fibrinolysis, full-dose therapeutic anticoagulation (e.g. vitamin K antagonists, dabigatran, heparin, hirudin, etc.) or high dose antiplatelet therapy.
• History of haemorrhagic central nervous system (CNS) event within 12 months prior to visit 1.
• History of haemoptysis or haematuria, active gastro-intestinal bleeding or ulcers and/or major injury or surgery within 3 months prior to visit 1.
• International normalised ratio (INR) >2 at visit 1.
• Prothrombin time (PT) and partial thromboplastin time (PTT) >150% of institutional ULN at visit 1.
• Planned major surgery during the trial participation, including lung transplantation, major abdominal or major intestinal surgery.
• History of thrombotic event (including stroke and transient ischemic attack) within 12 months of visit 1.
• Severe renal impairment (Creatinine clearance <30 mL/min calculated by Cockcroft-Gault formula at visit 1) or end-stage renal disease requiring dialysis.
• Treatment with n-acetylcysteine, prednisone >15 mg daily or >30 mg every 2 days OR equivalent dose of other oral corticosteroids or fluvoxamine within 2 weeks of visit 2.
• Treatment with azathioprine, cyclophosphamide, cyclosporine as well as any other investigational drug within 8 weeks of visit 2.
• Previous treatment with pirfenidone in the past three months prior to Visit 2 (Group 1 only).
• Previous treatment with nintedanib in the past 14 days prior to Visit 2.
• Permanent discontinuation of nintedanib or pirfenidone in the past due to adverse events considered drug-related.
• Known hypersensitivity to nintedanib, pirfenidone or their excipients; or to peanut or soya.
• A disease or condition which in the opinion of the investigator may interfere with testing procedures or put the patient at risk when participating in this trial.
• Alcohol or drug abuse, which in the opinion of the treating physician would interfere with treatment.
• Women who are pregnant, nursing, or who plan to become pregnant while in the trial.
• Women of childbearing potential not using highly effective methods of birth control per ICH M3, note 3, highly effective methods of birth control are defined as those, alone or in combination, that result in a low failure rate of less than 1% per year when used consistently and correctly such as implants, injectables, combined oral contraceptives, some intrauterine devices (IUDs), sexual abstinence or vasectomised partner. Barrier contraceptives (e.g. male condom or diaphragm) are acceptable if used in combination with spermicides (e.g. foam, gel). Contraception must be used for 28 days prior to and 3 months after nintedanib and pirfenidone administration.
• Patients not able to understand and follow study procedures including completion of diaries without help.
• Current smoker (vaping and e-cigarettes are acceptable)
