Basic information |
Public title |
A study to evaluate the long-term effect of pulmonary hypertension on prognosis, activities of daily living (ADL), cardiac function and pulmonary function in patients with COPD and idiopathic pulmonary fibrosis (IPF), respectively, according to baseline severity of pulmonary hypertension and the efficacy and safety of the Tracleer (bosentan hydrate) tablet for prognosis, activities of daily living, cardiac function and pulmonary function in patients with COPD and IPF, respectively, according to baseline severity of pulmonary hypertension. |

Assessment |
Primary outcomes |
(1) Influence on survival rate. |
Key secondary outcomes |
(1) Influence on ADL and Exercise tolerance
(2) Influence on cardiac function
Change in NT-proBNP or BNP etc, and cardiac function, and these association with ADL, survival rate, or severity of PH.
(3) Influence on PFT
Change in %DLco and so on, and these association with ADL, survival rate, or severity of PH
(4)change from baseline in TEI index and so on (including changes in ICT, ET, IRT,RA size, RV size, and TAPSE etc,) on echocardiography and results of Right heart catheter, and these association with ADL, survival rate, or severity of PH.

Interventions/Control_1 |
Treated subgroup
In patients with COPD without hypoxia (PaO2<60mmHg at rest or after 6 minutes walk) (WHO functional class II, III or IV), patients with Pulmonary hypertension with evidense of mPAP at rest=/>35mmHg : 20subjects
Bosentan will be administered basically according to the approved dosage and administration, as specified below. However, in this study conducted in accordance with routine clinical practice, the initial dosage may be used continuously if considered appropriate based on the patient's condition.
Treatment with bosentan in adults is usually initiated at a dose of 62.5 mg twice daily to be taken orally after breakfast and the evening meal for 4 weeks. From Week 5 of treatment, bosentan is administered at a dose of 125 mg twice daily to be taken orally after breakfast and evening meal. The dosage should be adjusted according to the patient's symptoms and tolerability, but should not exceed 250 mg per day.
Duration of study drug administration: 24 months
In addition, Interventions/Control 11 and 12 is described in Interventions/control 10. |
