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

Eligibility criteria:

        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
