About this study

Official title: A Prospective Randomized, Double Blind, Placebo-controlled, Safety and Efficacy Study of Bosentan as add-on Therapy in Progressive Pulmonary Sarcoidosis

Progressive pulmonary sarcoidosis occurs in up to twenty percent of patients who require persistent treatment, but available treatment options have shown considerable long-term toxicity and uncertain or unproven efficacy. In these patients, pulmonary fibrosis and pulmonary hypertension are common complications which have major prognostic impact. Endothelin-1 (ET-1) has been demonstrated to play a key role in pulmonary fibrosis and pulmonary hypertension, and a potential role in pulmonary sarcoidosis. ET-1 is a potent vasoconstrictor and can promote fibrosis, cell proliferation, and remodeling, and is pro-inflammatory. Preliminary data have shown the therapeutic potential of the endothelin receptor antagonist (ERA) bosentan in sarcoidosis associated pulmonary hypertension.

In this light, the therapeutic potential of bosentan as an add-on treatment in progressive pulmonary sarcoidosis needs to be evaluated.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • bosentanDrug

    62.5 mg tablets b.i.d. administered orally for 4 weeks followed by the maintenance dose of 125 mg b.i.d. (62.5 mg b.i.d. if body weight < 40 kg/90 lb)

  • placeboDrug

    identical preparation as the study drug, but without the active substance, administered b.i.d.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Treatment efficacy is assessed by a composite clinical score, including six parameters: Pulmonary function test (FVC and DLCO), Blood gas analysis (AaDO2), HRCT (Oberstein score), 6 minute walk test (6-MWD), Dyspnoea (ATS dyspnea scale)

    Measured: 6 months

Secondary outcomes (2)
  1. Assess safety and tolerability of bosentan in progressive pulmonary sarcoidosis

    Measured: 6 months

  2. To evaluate the efficacy of bosentan treatment in the subgroups of patents with and without sarcoidosis-associated pulmonary hypertension.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing bosentan in people with Sarcoidosis and Pulmonary Hypertension, run by Daniel Doberer at 2 sites in Austria.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 26 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 15 Sep 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Austria. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was stopped early (reason given: Not enough patients with the specified criteria could not). Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Treatment efficacy is assessed by a composite clinical score, including six parameters: Pulmonary function test (FVC and DLCO), Blood gas analysis (AaDO2), HRCT (Oberstein score), 6 minute walk test (6-MWD), Dyspnoea (ATS dyspnea scale) (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Sep 2016.
