Key inclusion & exclusion criteria
Inclusion criteria:
Any Patient with Chronic Obstructive Pulmonary Disease or Sarcoid with Pulmonary Hypertension. Pulmonary hypertension is defined as a mean pulmonary artery pressure in excess of 20mmHg at rest. Pulmonary hypertension is defined as an elevated mean pulmonary artery pressure of 20 mmHg or greater at rest or 30 mmHg with exercise.
Are the trial subjects under 18? no
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
F.1.3 Elderly (>=65 years) yes
F.1.3.1 Number of subjects for this age range

Exclusion criteria:
Bosentan is contraindicated in patients with moderate to severe liver dysfunction and therefore this is an exclusion criteria.

There is limited experience with Bosentan in patients with a body weight below 40 kg, although this is not an absolute exclusion criteria this would require more frquent monintoring and is a relative contraindication for inclusion in the trial.

Excessive age is a relative contraindication given the number of clinic visits(>85 years old).

Children Safety and efficacy in patients under the age of 12 years have not been established so this is an exclusion criteria. (Age <12)

Pregnancy is absolute ecxlusion to the trial - therefore females entering the trial of child bearing age would need two forms of contraception and a pregnancy test prior to entry.

Health Condition(s) or Problem(s) studied
Pulmonary Hypertension secondary to Chronic Obstructive Pulmonary Disease and secondary to Sarcoid Patients devolop pulmonary hypertension for various reasons, two common causes are Chronic Obstructive Pulmonary disease and Sarcoid. Once developed it may go on to cause right heart failure and severe breathlessness and eventually death. We believe that the use of bosentan may lower the pulmonary hypertension and improve symptoms.
MedDRA version: 8.1 Level: LLT Classification code 10037400 Term: Pulmonary hypertension
Intervention(s)

Trade Name: Tracleer
Product Name: tracleer
Pharmaceutical Form: Film-coated tablet
INN or Proposed INN: Bosentan monohydrate
CAS Number: 147536978
Concentration unit: mg milligram(s)
Concentration type: equal
Concentration number: 62.5mg-125mg

Primary Outcome(s)

Primary end point(s): The primary end points in the trial would to be to review patients before treatment and after 1 year of treatment. The end points studied would be;
1 Survival
2 Pulmonary pressures monitored by Right Heart Catheter.
3 Exercise tolerance - measured by the six minute walk test.
4 Lung function tests
5 Quality of Life assessment
6 Echo appearence of right ventricle and pulmonary pressures

Main Objective: Patients devolop pulmonary hypertension for various reasons, two common causes are Chronic Obstructive Pulmonary disease and Sarcoid. Once developed it may go on to cause right heart failure and severe breathlessness and eventually death.

We believe that the use of bosentan may lower the pulmonary hypertension and improve symptoms. We therefore wish to trial the use of bosenten in patients with secondary pulmonary hypertension and see if after a period of treatment their pulmonary pressure falls, if their lung function improves, if their exercise tolerance improves and if quality of life improve.
Secondary Objective: To ensure that Bosentan is a safe and well tolerated treatment in patients with secondary pulmonary hypertension. This would be answered by monitoring patients very carefully whilst on the treatment and reporting any side effects.
