The main purpose of this study is to see how GLPG1690 works together with your current standard treatment on your lung function and IPF disease in general. The study will also investigate how well GLPG1690 is tolerated (for example if you get any side effects while on study drug).

Accepts Healthy Volunteers

Inclusion Criteria

  • Male or female subject aged ≥40 years on the day of signing the Informed Consent Form (ICF).
  • A diagnosis of IPF within 5 years prior to the screening visit, as per applicable American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Latin American Thoracic Association (ALAT) guidelines at the time of diagnosis.
  • Chest high-resolution computed tomography (HRCT) historically performed within 12 months prior to the screening visit and according to the minimum requirements for IPF diagnosis by central review based on subject's HRCT only (if no lung biopsy (LB) available), or based on both HRCT and LB (with application of the different criteria in either situation). If an evaluable HRCT <12 months prior to screening is not available, an HRCT can be performed at screening to determine eligibility, according to the same requirements as the historical HRCT.
  • Subjects receiving local standard of care for the treatment of IPF, defined as either pirfenidone or nintedanib at a stable dose for at least two months before screening, and during screening; or neither pirfenidone or nintedanib (for any reason). A stable dose is defined as the highest dose tolerated by the subject during those two months.
  • The extent of fibrotic changes is greater than the extent of emphysema on the most recent HRCT scan (investigator-determined).
  • Meeting all of the following criteria during the screening period: FVC ≥45% predicted of normal, Forced expiratory volume in 1 second (FEV1)/FVC ≥0.7, diffusing capacity of the lung for carbon monoxide (DLCO) corrected for Hb ≥30% predicted of normal.
  • Estimated minimum life expectancy of at least 30 months for non IPF related disease in the opinion of the investigator.
  • Male subjects and female subjects of childbearing potential agree to use highly effective contraception/preventive exposure measures from the time of first dose of investigational medicinal product (IMP) (for the male subject) or the signing of the ICF (for the female subject), during the study, and until 90 days (male) or 30 days (female) after the last dose of IMP.
  • Able to walk at least 150 meters during the 6-Minute Walk Test (6MWT) at screening Visit 1; without having a contraindication to perform the 6MWT or without a condition putting the subject at risk of falling during the test (investigator's discretion). The use of a cane is allowed, the use of a stroller is not allowed at all for any condition. At Visit 2, for the oxygen titration test, resting oxygen saturation (SpO2) should be ≥88% with maximum 6 L O2/minute; during the walk, SpO2 should be ≥83% with 6 L O2/minute or ≥88% with 0, 2 or 4 L O2/minute.

Exclusion Criteria

  • History of malignancy within the past 5 years (except for carcinoma in situ of the uterine cervix, basal cell carcinoma of the skin that has been treated with no evidence of recurrence, prostate cancer that has been medically managed through active surveillance or watchful waiting, squamous cell carcinoma of the skin if fully resected, and Ductal Carcinoma In Situ).
  • Acute IPF exacerbation within 6 months prior to screening and/or during the screening period. The definition of an acute IPF exacerbation is as follows: Previous or concurrent diagnosis of IPF; Acute worsening or development of dyspnea typically < 1 month duration; Computed tomography with new bilateral ground-glass opacity and/or consolidation superimposed on a background pattern consistent with usual interstitial pneumonia pattern and deterioration not fully explained by cardiac failure or fluid overload.
  • Lower respiratory tract infection requiring antibiotics within 4 weeks prior to screening and/or during the screening period.
  • Interstitial lung disease associated with known primary diseases (e.g. sarcoidosis and amyloidosis), exposures (e.g. radiation, silica, asbestos, and coal dust), or drugs (e.g. amiodarone).
  • Diagnosis of severe pulmonary hypertension (investigator- determined).
  • Unstable cardiovascular, pulmonary (other than IPF), or other disease within 6 months prior to screening or during the screening period (e.g. acute coronary disease, heart failure, and stroke).
  • Had gastric perforation within 3 months prior to screening or during screening, and/or underwent major surgery within 3 months prior to screening, during screening or have major surgery planned during the study period.
  • Moderate to severe hepatic impairment (Child-Pugh B or C) and/or abnormal liver function test (LFT) at screening, defined as aspartate aminotransferase (AST), and/or alanine aminotransferase (ALT), and/or total bilirubin ≥1.5 x upper limit of the normal range (ULN), and/or gamma glutamyl transferase (GGT) ≥3 x ULN. Retesting is allowed once for abnormal LFT.
  • Abnormal renal function defined as estimated creatinine clearance, calculated according to Cockcroft-Gault calculation (CCr) <30 mL/min. Retesting is allowed once.
  • Use of any of the following therapies within 4 weeks prior to screening and during the screening period, or planned during the study: warfarin, imatinib, ambrisentan, azathioprine, cyclophosphamide, cyclosporine A, bosentan, methotrexate, sildenafil (except for occasional use), prednisone at steady dose >10 mg/day or equivalent.
