About this study

Official title: A Phase 3 Randomized, Double Blind, Vehicle Controlled Study Investigating the Safety and Efficacy of HP802-247 in the Treatment of Venous Leg Ulcers >12 cm2 to ≤ 36 cm2

This study is being done to find out if an investigational product called HP802-247 can help people with venous leg ulcers. Investigational means that HP802-247 has not been approved by the U.S. Food and Drug Administration (FDA).

At least 250 subjects will participate. The study is going to be conducted in approximately 50 sites in the United States and Canada.

Read the detailed description

This research is being done to compare the efficacy of HP802-247 plus compression therapy against Vehicle plus compression therapy in achieving complete wound closure over the 16-week treatment period. Vehicle looks the same as HP802-247 but contains no cells. Target wound status is evaluated at each study visit (closed, open, reopened). At wound closure or completion of treatment all subject will enter an observational safety followed up period which ends at one year after initial exposure to test article.

What is being measured

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

  1. Wound Closure

    Compare HP802-247 plus compression therapy against Vehicle plus compression therapy for proportion of subjects with complete wound closure over the 16-week treatment period from baseline.

    Measured: 16 Weeks

Secondary outcomes (1)

  1. Time in Days to Closure

    Compare the efficacy of HP802-247 plus compression therapy against Vehicle plus compression therapy in achieving complete wound closure, based on time in days to closure over the 16-week treatment period from baseline.

    Measured: 16 Weeks

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing HP802-247 in people with Venous Leg Ulcers, run by Healthpoint at 43 sites in 3 countries.

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 9 inclusion and 9 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 26 Jul 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 43 sites in United States, Canada, Puerto Rico. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 26 Jul 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?

Wound Closure (time frame: 16 Weeks). 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 NCT01737762, 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 26 Jul 2017.
