What participants receive

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

  • OPAL ADrug

    OPAL A will be supplied in two formulations: as a Filtrate (0.5 mL per cm2 of ulcer area, applied into the ulcer cavity) and as a Cream (about 1 to 5 g applied as a thin smear on surrounding skin). Both formulations will be applied daily. However, if the ulcer begins to hypergranulate, the OPAL A Filtrate will only be administered once every 72 hours.

  • PlaceboDrug

    Placebo will be supplied in two formulations: as a Filtrate (0.5 mL per cm2 of ulcer area, applied into the ulcer cavity) and as a Cream (about 1 to 5 g applied as a thin smear on surrounding skin). Both formulations will be applied daily. However, if the ulcer begins to hypergranulate, the Placebo Filtrate will only be administered once every 72 hours.

What is being measured

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

  1. Frequency and severity of adverse events

    Measured: Weekly from Week -4 to Week 12

  2. Physical examination findings and vital signs

    Measured: Week -6, Day 0 and Weeks 6 and 12

  3. Clinical laboratory assessments (full blood count [FBC], blood chemistry, liver function tests and coagulation parameters) as changed from Day 0 (i.e., baseline/randomization).

    Measured: Week -6, Day 0, Weeks 3, 6, 12

Secondary outcomes (8)
  1. Time to 50% wound closure

    Measured: Weekly from Weeks -6 to 12

  2. Time to 100% wound closure

    Measured: Weekly from Weeks -6 to 12

  3. Proportion of participants with 50% or greater wound closure, or 100% wound closure at 12 weeks

    Measured: Weekly from Weeks -6 to 12

  4. Percentage change in wound surface area at 12 weeks

    Measured: Weekly from Weeks -6 to 12

  5. Participant's assessment of pain during wound dressing and wound pain in the 24 hours before each study visit (assessed using the McGill short-form pain survey)

    Measured: Weekly from Week 0 to 12

  6. Quality of life (QoL) scores and health state (for determination of quality-adjusted life years [QALYs]; assessed using the SF-12 health survey and the McGill short-form pain survey)

    Measured: Day 0 and Weeks 6 and 12

  7. Participant's and clinician/nurse overall satisfaction with treatment

    Measured: Weeks 6 and 12

  8. Use of health care resources/informal care

    Measured: Day 0 and Weekly from Week 1 to 12

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing OPAL A in people with Venous Ulcer and Pressure Ulcer, run by Phoenix Eagle Company at 1 site in Australia.

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 13 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: paused, as of the sponsor's last update on 30 Oct 2014. 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 Australia. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

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?

Frequency and severity of adverse events (time frame: Weekly from Week -4 to Week 12). The study lists 3 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 30 Oct 2014.
