b) calculating a specific three-dimensional structural model of the subject's respiratory system using the three-dimensional image data of step a) to determine one or more outcome parameters as described in WO2014125059;
c) administering a daily dose of between 100 mg to 1000 mg to the subject of a compound according to Formula I (Cpd 1), or a pharmaceutically acceptable salt thereof:
d) repeating steps a and b above after administration of the compound;
e) comparing the three-dimensional structural models and/or outcome parameters of step b) and d) with each other;
f) calculating the response to the treatment of said subject from step e);
g) determining whether the dose of the compound according to Formula I should be increased, decreased or maintained at the same level based on the results obtained in step f).

10 . The method according to any one of claims 1 - 7 , comprising measuring the forced vital capacity FVC in the subject, wherein said FVC increases by at least 1 mL, at least 2 mL, at least 3 mL, at least 4 mL, at least 5 mL, at least 6 mL, at least 7 mL or at least 8 mL over a period of 12 weeks.
11 . The method according to any one of claims 1 - 7 , comprising measuring the airway volume wherein said airway volume decrease is no more than 5 mL/L, no more than 4 mL/l, or no more than 3 mL/L after 12 weeks.
12 . The method according to any one of claims 1 - 7 , comprising measuring the airway resistance wherein said airway resistance increase is at least 0.05 kPa/s, at least 0.06 kPa/s, at least 0.07 kPa/s, at least 0.08 kPa/s, at least 0.09kPa/s, or at least 1.0 kPa/s after 12 weeks.
13 . The method according to claim 1 , wherein the compound or a pharmaceutically acceptable salt thereof of step c) is administered as a pharmaceutical composition.
14 . The method according to claim 12 , wherein the pharmaceutical composition comprises a pharmaceutically acceptable carrier, and an effective amount of the compound according to Formula I.
15 . The method according to claim 1 , wherein the fibrotic disease is IPF.
16 . A method of treating idiopathic pulmonary fibrosis comprising the steps of administering a subject a daily dose of compound according to formula I of 100 mg or more, such as 100 to 1000 mg, 100 to 600 mg, 200 to 1000 mg, or, 200 to 600 mg.
