About this study

This is an open label, randomized, interventional study indented to find the efficacy of different treatment regimens in treatment of pulmonary hypertension secondary to lung disease and/or hypoxia.This is to find out when to start combination therapy (sildenafil plus bosentan) in treatment of pulmonary hypertension secondary to lung disease and/or hypoxia.

Read the detailed description

This is an open label, randomized, interventional study indented to find the efficacy of different treatment regimens in treatment of pulmonary hypertension secondary to lung disease and/or hypoxia. It involves 3 arms, one getting monotherapy with sildenafil for 6 months, 2nd getting bosentan monotherapy initially for 3 months and then combination of sildenafil and bosentan for 3 months, 3rd getting combination sildenafil and bosentan from the beginning for 6 months. The aim is to decide when is the best time to start combination therapy either from start or at the time of drug failure. Improvement will be assessed by change in functional class, pulmonary pressures measured by ECHO, pulmonary function test, six minute walk test and biochemical markers. Lack of randomized trials and Indian data is there on the subject. Also adverse events and serious adverse events will be closely monitored and reported to the ethics committee and DCGI immediately.

Being tested
Sildenafil, Bosentan

What participants receive

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

  • SildenafilDrug

    20 mg initially and then increased to 20 mg TDS if there is no fall in BP

  • BosentanDrug

    Bosentan 62.5 mg BD initially for 1 month and then increased to 125 mg BD

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Sildenafil and Bosentan in people with Pulmonary Hypertension Secondary to Lung Disease and/or Hypoxia, run by All India Institute of Medical Sciences at 1 site in India.

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 5 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: status not confirmed, as of the sponsor's last update on 29 Jan 2013. 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 India. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Results are not available in the source record.

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

Contact Sajal Ajmani, MBBS (919873570408, sajalajmani@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Echocardiogram (time frame: 6 months). The study lists 5 primary outcomes in all. 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 29 Jan 2013.
