1.Men or women aged from =18 to =80 years
2.Diagnosed with one of the following (confirmed using a multidisciplinary approach, as per ATS/ERS/JRS/ALAT guidelines [1]):
-Major IIPs diagnosis or suspected as one of the following:
?Idiopathic pulmonary fibrosis
?Idiopathic nonspecific interstitial pneumonia
?Respiratory bronchiolitis–interstitial lung disease
?Desquamative interstitial pneumonia
?Cryptogenic organizing pneumonia
?Acute interstitial pneumonia
-Rare IIPs diagnosis by one of the following:

-Unclassifiable idiopathic interstitial pneumonias
3.FVC = 45 %
4.6MWD = 150 m to = 450 m (under stable O2 supplementation via nasal cannula)
5.Diagnosis of PH confirmed by right heart catheter (RHC) with mPAP = 25 mmHg and PAWP =15 mmHg at rest
6.Systolic blood pressure (SBP) = 95 mmHg and no signs or symptoms of hypotension
7.WHO functional class II-IV
8.Women of childbearing potential can only be included in the study if a pregnancy test is negative. Women of childbearing potential must agree to use adequate contraception when sexually active. ‘Adequate contraception’ is defined as any combination of at least 2 effective methods of birth control, of which at least one is a physical barrier (e.g. condoms with hormonal contraception or implants or combined oral contraceptives, certain intrauterine devices). Adequate contraception is required from the signing of the informed consent form up until 4 weeks after the last study drug administration

Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 96
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range 24

2. Active state of hemoptysis or pulmonary hemorrhage, including those events managed by bronchial artery embolization
3. Any history of bronchial artery embolization or massive hemoptysis within 3 months prior to screening. Massive hemoptysis being defined as acute bleeding >240 mL in a
24-hour period or recurrent bleeding >100 mL/d over several days
4. History of acute lung infection or acute exacerbation within 4 weeks prior to screening
5. Reasonable likelihood of receiving a lung transplant within the 26 week main study period
6. Pulmonary veno-occlusive disease
7. Difference > 15% between the two baseline 6MWD test
8. Saturation of peripheral oxygen (SpO2) remains < 92 % with up to 6 L/minute supplemental oxygen delivered by nasal cannula at rest
9. Forced expiratory volume in one second (FEV1)/FVC <0.65 after bronchodilator administration
10. CO2 > 45 mmHg
11. Other known cause of ILD including:
a. connective tissue disease
b. sarcoidosis
c. chronic hypersensitivity pneumonitis
d. significant environmental exposure likely to be the cause of the patients ILD (such as asbestos or silica exposure)
12. Extent of emphysema greater than the extent of fibrotic changes (honeycombing, reticular changes) on HRCT scan
13. Initiation or change in cytotoxic, immunosuppressive, cytokine modulating therapy within 3 months prior to screening. Such agents might include azathioprine, cyclophosphamide, corticosteroids, etanercept, tumor necrosis factor alpha (TNFa) inhibitors and others
14. Pirfenidone and any other drug approved specifically for IPF initiated within 3 months prior to screening
15. Any specific treatment for PAH/PH within 3 months prior to screening
16. Active smoking of tobacco of any type or quantity
17. Active participation in a Pulmonary Rehabilitation program, defined as a structured exercise and rehabilitation program supervised by a physician, respiratory therapist and/or a physiotherapist. Patients who have completed a course of Pulmonary Rehabilitation and are in the maintenance phase of the program are eligible for study enrollment
18. Concomitant use of the following medication: nitrates or NO donors (such as amyl nitrite) in any form, phosphodiesterase 5 inhibitors (such as sildenafil, tadalafil, vardenafil) and non-specific phosphodiesterase (PDE) inhibitors (theophylline, dipyridamole),
19. Severe hepatic impairment (Child Pugh C)
20. Creatinine clearance < 15 ml/min or on dialysis
21. Pregnant women (i.e. positive pregnancy test or other signs of pregnancy), or breast feeding women, or women of childbearing potential not using adequate contraception (as defined in the aforementioned inclusion criterion) and not willing to agree to 4-weekly pregnancy testing from Visit 1(first administration of study drug) onwards until 4 weeks after last study drug intake
22. Previous randomization to treatment during this study
23. Participation in another clinical study with an investigational drug or a medical device within 30 days prior to randomization (phase I-III clinical studies). Active participation in an early access program for an IPF agent, specifically pirfenidone or nintedanib
