What is being measured

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

  1. Total Number of AKs in Treatment Area

    Count of observed lesions in the treatment area, which include lesions that recurred after on-study cryotherapy as well as newly occurring lesions. AK lesions in the treatment area at baseline (maximum of 2) were excluded for this endpoint.

    Measured: Week 52

Secondary outcomes (8)
  1. Proportion of Subjects With 0 AKs

    Normalized based on number of lesions present at Baseline

    Measured: Week 4

  2. Subject Satisfaction Score

    Subject satisfaction score

    1. = Excellent (very satisfied)
    2. = Good (moderately satisfied)
    3. = Fair (slightly satisfied)
    4. = Poor (not satisfied at all) Unknown

    Measured: Week 52

  3. Proportion of Subjects With 0 AKs

    Normalized based on number of lesions present at Baseline

    Measured: Week 12

  4. Proportion of Subjects With 0 AKs

    Normalized based on number of lesions present at Baseline

    Measured: Week 24

  5. Proportion of Subjects With 0 AKs

    Normalized based on number of lesions present at Baseline

    Measured: Week 36

  6. Proportion of Subjects With 0 AKs

    Normalized based on number of lesions present at Baseline

    Measured: Week 52

  7. Recurrence Rate

    Recurrence rate of all lesions that were complete responses following on-study cryotherapy (at Visit 3/Baseline).

    Measured: Week 52

  8. Duration of Response

    Duration of response is the elapsed number of weeks from the Baseline visit until a lesion recurred or Week 52, whichever comes first

    Measured: within 52 weeks after Baseline

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Aminolevulinic Acid, BLU-U and Cryotherapy in people with Actinic Keratosis, run by DUSA Pharmaceuticals, Inc. at 8 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 3 inclusion and 15 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 24 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 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. 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?

Yes. Results are posted in the registry (first posted 21 Sep 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?

Total Number of AKs in Treatment Area (time frame: Week 52). 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 NCT02239679, 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 24 Aug 2018.
