About this study
Pulmonary arterial hypertension (PAH), or high blood pressure in the lungs, is common in patients with congenital heart disease. Historically these patients suffered significant morbidity and mortality due to a lack of effective therapies. More recently, advanced therapies which target the mechanisms underlying the development and progression of PAH have been introduced into clinical care. Oral, intravenous, subcutaneous, and inhaled therapies are all available for the treatment of PAH. Patients with PAH are first treated with oral agents (including sildenafil and bosentan). However, if these agents fail to achieve the desired effect for the patient, intravenous or inhaled therapies may be initiated. Combination therapy with multiple agents is common in routine clinical care. However, the most efficacious therapeutic regimen has yet to be delineated. The present study seeks to evaluate the efficacy of one specific regimen: iloprost, an inhaled prostacyclin derivative, used in combination with oral therapy (sildenafil and/or bosentan). Iloprost has been approved by the FDA for use in this patient population. Adults with PAH already receiving oral therapy will be invited to participate in this study. Iloprost will be added to their current therapeutic regimen for a period of three months, with pre- and post-treatment assessments. These will include a cardiopulmonary exercise test, BNP (a blood test), six minute walking distance, and a quality of life questionnaire.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Pulmonary arterial hypertension (PAH), or high blood pressure in the lungs, is common in patients with congenital heart disease. Historically these patients suffered significant morbidity and mortality due to a lack of effective therapies. More recently, advanced therapies which target the mechanisms underlying the development and progression of PAH have been introduced into clinical care. Oral, intravenous, subcutaneous, and inhaled therapies are all available for the treatment of PAH. Patients with PAH are first treated with oral agents (including sildenafil and bosentan). However, if these agents fail to achieve the desired effect for the patient, intravenous or inhaled therapies may be initiated. Combination therapy with multiple agents is common in routine clinical care. However, the most efficacious therapeutic regimen has yet to be delineated. The present study seeks to evaluate the efficacy of one specific regimen: iloprost, an inhaled prostacyclin derivative, used in combination with oral therapy (sildenafil and/or bosentan). Iloprost has been approved by the FDA for use in this patient population. Adults with PAH already receiving oral therapy will be invited to participate in this study. Iloprost will be added to their current therapeutic regimen for a period of three months, with pre- and post-treatment assessments. These will include a cardiopulmonary exercise test, BNP (a blood test), six minute walking distance, and a quality of life questionnaire.

Questions about this trial
What is this clinical trial studying?
A study testing Iloprost in people with Pulmonary Arterial Hypertension and Congenital Heart Disease, run by University of California, Los Angeles at 1 site in United States.
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 3 inclusion and 6 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 26 Jan 2015. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 29 Dec 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Safety and Tolerability (time frame: 3 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01319045, which also lists 13 linked publications.
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 26 Jan 2015.
