Secondary outcomes (17)
  1. Local tolerability by Investigator's assessment

    Local tolerance to treatment will be assessed by the Investigator. Wound tolerability parameters will be presented in categories of appearance of inflammation, amount of exudate present, hemorrhage, presence of slough/necrotic tissue, presence of granulation tissue and hypergranulation.

    Measured: Compare Investigator's local tolerability assessments up to Week 26 between the ILP100-Topical and Placebo treatment arms.

  2. Local tolerability by Independent Assessor's assessment

    Local tolerance to treatment will be assessed by the Independent Assessor. Wound tolerability parameters will be presented in categories of appearance of inflammation, amount of exudate present, hemorrhage, presence of slough/necrotic tissue, presence of granulation tissue and hypergranulation.

    Measured: Compare local tolerability up to Week 26 between the ILP100-Topical and Placebo treatment arms.

  3. Proportion of subjects with a local tolerability parameter Grade ≥ 2 per Investigator's Assessment

    The proportion of subjects with a local tolerability parameter grade ≥ 2 will be calculated (grading system=0 to 3, where 3 is severe). Local tolerance to treatment, infection and wound healing will be assessed by the Investigator. Wound tolerability parameters include appearance of inflammation, amount of exudate present, hemorrhage, presence of slough/necrotic tissue, presence of granulation tissue and hypergranulation.

    Measured: Compare the ILP100-Topical and Placebo treatment arms up to Week 26.

  4. Proportion of subjects with a local tolerability parameter Grade ≥ 2 per Independent Assessor's Assessment

    The proportion of subjects with a local tolerability parameter grade ≥ 2 will be calculated (grading system=0 to 3, where 3 is severe). Local tolerance to treatment, infection and wound healing will be assessed by the Independent Assessor. Wound tolerability parameters include appearance of inflammation, amount of exudate present, hemorrhage, presence of slough/necrotic tissue, presence of granulation tissue and hypergranulation.

    Measured: Compare the ILP100-Topical and Placebo treatment arms up to Week 26.

Where is the study taking place?

The record lists 2 sites in Sweden. 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?

The study was stopped early (reason given: Patient recruitment issues). 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?

Compare incidence of adverse events (AEs) between treatment groups (time frame: Compare between the ILP100-Topical and Placebo treatment arms up to Week 26.). The study lists 2 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 NCT05608187, which also lists 3 linked publications.

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.
