About this study
Official title: An Open Monocentric Pilot Study to Investigate the Potential of Imiquimod 5% Cream to Detect Residual and to Prevent Recurrence of Lentigo Maligna After Surgical Excision
This is a prospective, longitudinal, uncontrolled study with follow-up for 5 years.Patients having undergone surgical excision of lentigo maligna (LM) or lentigo maligna melanoma (LMM) will be invited to this study. Eligible patients will start treatment with imiquimod 6 weeks after the excision, the treatment will last for up to 12 weeks. Inflammatory reactions and the occurrence of residual lesions will be documented. The healing effect will be determined (initial clearance rate) 20 weeks after start of treatment with imiquimod. All patients who were enrolled (=exposed to imiquimod in this study) will be followed up for 5 years or until recurrence of the LM or LMM
Read the detailed description
Imiquimod (Aldara) 5% cream will be applied starting 6 weeks post-surgery to an area within 5 cm of treatment margins to each side of the original scar of the LM or LMM excision. Time period between removal of stitches and first administration of imiquimod should be 4 weeks, correspondent to approximate 6 weeks post surgery. Imiquimod cream is applied once daily. Each patient will begin with the application 3x/week. After two weeks of treatment the inflammation response to imiquimod will be assessed. If no or only minor inflammation is detectable in the treatment area, the dosing schedule will be increased to 5x/week. After four weeks of treatment the inflammation response will be assessed again. If still no or only minor inflammation is detectable, application will be extended to daily use. An interruption of the treatment with imiquimod cream is considered if severe local inflammatory reaction occurs, severe systemic reactions are apparent or if super-infection is observed at the treatment area. The primary objective of the study is to investigate the potential of imiquimod 5% cream to eliminate possible subclinical lesions of LM that resides after surgical excision by determining the long-term recurrence rates. Secondary objectives of the study describe the incidence of subclinical residual lesions and local skin reactions.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Imiquimod in people with Lentigo Maligna, run by Medical University of Graz at 2 sites in Austria.
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 7 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: status not confirmed, as of the sponsor's last update on 13 Aug 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 Austria. 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 combined 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.
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?
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?
Elimination of possible subclinical lesions of LM that resides after surgical excision by determining the long-term recurrence rates. (time frame: 60 months). 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 13 Aug 2019; AzTrials last refreshed its copy on 8 Nov 2026.
