About this study

Official title: An Open-Label, Dose Titration Study to Assess the Safety, Tolerability, and Hemodynamic Response of PB1046, A Sustained-Release Analogue of Vasoactive Intestinal Peptide, In Adult Subjects With Pulmonary Arterial Hypertension

PB1046-PT-CL-0005 is an open-label, dose-titration study to assess the safety, tolerability, and hemodynamic effects of individually dose-titrated PB1046 administered by weekly subcutaneous injection for 8 weeks in adult subjects with PAH who have a permanently implanted hemodynamic monitor in the distal pulmonary artery. The primary objectives of the study are to assess the overall safety, tolerability, and hemodynamic profile of a PB1046 across an individually titrated dose range.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing PB1046 Subcutaneous Injection in people with Pulmonary Arterial Hypertension, run by PhaseBio Pharmaceuticals Inc. at 2 sites 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 8 inclusion and 16 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 8 Oct 2019. 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 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.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Adverse Events (time frame: Pre-dose to 28 days after last dose). The study lists 12 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 8 Oct 2019.
