• Bleeding risk, any of the following:
  • Known genetic predisposition to bleeding.
  • Patients who require:
  • Fibrinolysis, full-dose therapeutic anticoagulation (e.g. vitamin K antagonists, direct thrombin inhibitors, direct oral anticoagulants, heparin, hirudin) ii. High dose antiplatelet therapy (> 325 mg/day of aspirin; > 75 mg/day ticlodipine or clopidogrel; any dose of other 2b3a anti-platelet agents)
• Coagulation parameters: International normalized ratio (INR) >2, prolongation of prothrombin time (PT) and activated partial thromboplastin time (aPTT) by >1.5 x ULN
  • Note: Prophylactic low dose heparin or heparin flush as needed for maintenance of an indwelling intravenous device (e.g. less than or equal to enoxaparin 40 mg subcutaneously (SC) per day or heparin 5000 units SC every eight hours), low-dose FXa inhibitors (rivaroxaban/apixaban: 2.5mg twice daily (max 5mg/day), edoxaban: 15mg/day), as well as prophylactic use of antiplatelet therapy (e.g. acetyl salicylic acid [ASA] up to 325 mg/day, or clopidogrel at 75 mg/day, or equivalent doses of other antiplatelet therapy) are not prohibited.
• Evidence of active infection (chronic or acute) based on clinical exam or laboratory findings.

Egyéb

• Relevant airways obstruction (pre-bronchodilator Forced Expiratory Volume in one second to forced vital capacity ratio less than 70% (FEV1/FVC < 0.7))
• In the opinion of the Investigator, other clinically significant pulmonary abnormalities.
• Emphysema ≥ 50% on HRCT assessed by the investigator, or the extent of emphysema is greater than the extent of fibrosis according to reported results from the most recent chest HRCT.
• ILD associated with other known causes
• Simultaneous use of pirfenidone and nintedanib at screening.
• Women who are pregnant, nursing, or who plan to become pregnant while in the trial.
• Patients not able to understand or follow trial procedures including completion of self- administered questionnaires without help.

• Male or female age 40 years or older
• IPF Diagnosis:
  • Satisfying the 2022 American Thoracic Society/European Respiratory Society /Japanese Respiratory Society/Latin American Thoracic Association (ATS/ERS/JRS/ALAT) diagnostic criteria (Raghu 2022) confirmed by the investigator

Allowable antifibrotic therapy includes: pirfenidone, nintedanib, nerandomilast, pirfenidone with nerandomilast, or nintedanib with nerandomilast (combination of pirfenidone and nintedanib not allowed).
