About this study

Official title: An Open Label, Single-arm Study Evaluating a New Thermostable Formulation of FLOLAN™ in Japanese Subjects With Pulmonary Arterial Hypertension (PAH)

This study is a Phase IV, open-label, single-arm study to assess the safety and the necessity of dose adjustment after switching to FLOLAN injection prepared with the reformulated diluent in Japanese patients with PAH who are receiving higher doses of FLOLAN injection than in other countries. The objective is to evaluate the safety and tolerability of the thermostable formulation of FLOLAN injection (that is [i.e.], FLOLAN injection prepared with the reformulated diluent) when switched from the existing FLOLAN injection treatment (i.e., FLOLAN injection prepared with the currently marketed diluent). The study will include a screening visit, a run-in period of a maximum of 4 weeks with the existing FLOLAN treatment (i.e., FLOLAN injection prepared with the currently marketed diluent), a 4-week treatment period with the thermostable formulation of FLOLAN injection (i.e., FLOLAN injection prepared with the reformulated diluent) and a one-week follow-up visit. Adequate number of subjects will be enrolled in the study in order to have 10 subjects to complete assessments at 4 weeks, including at least 5 subjects as a subset of subjects who consent to undergo right heart catheterisation (RHC) over 24-hour and at Week 4. FLOLAN is a registered trademark of the GlaxoSmithKline [GSK] group of companies.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing FLOLAN injection with currently marketed diluent and FLOLAN injection with reformulated diluent in people with Cardiovascular Disease, run by GlaxoSmithKline at 1 site in Japan.

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 10 inclusion and 10 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: finished, as of the sponsor's last update on 6 Apr 2017. 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 Japan. 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?

Yes. Results are posted in the registry (first posted 6 Apr 2017). 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?

Number of Participants With Any Adverse Event (AE) or Serious Adverse Event (SAE) (time frame: Up to Week 4). The study lists 19 primary outcomes in all. 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 NCT02705807, which also lists 1 linked publication.

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 6 Apr 2017.
