Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: 5in vivo comparison of effect of imiquimod 3.75% in detection of subclinical lesions of actinic keratosis using high definition optical coherence tomography (HD-OCT) and Reflectance confocal microscopy (RCM).;Secondary Objective: clinical classification os all lesion observed clinical evaluation of actinic keratosis adverse events;Primary end point(s): Number of subclinical lesions previously determined (at W0) by non invasive methods by RCM and /or HD-OCT that become clinically visible and clear during treatment with IMIQ 3.75% at week 14.;Timepoint(s) of evaluation of this end point: week 14 | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): b) Clinical classification in all areas at any visit of the predefined diagnostic areas for type of AK lesions. The study area will be evaluated for the presence and number of: 1. Non-affected; 2. Subclinical AK; 3. Clinical visible AK. (schematics with a grid will be used to asses the presence and localisation of AK , new AK, subclinical AK and inflammation on clinical naked-eye examination ). c) OCT/RCM evaluation of clinically apparent AK at W6 and W14 and additionally at W2 and W4 on decision of investigator (for inflammatory reactions) d) Number of countable new AK lesions at every evaluation up to Week 14 e) Number of subclinical lesions turning visible under therapy and cleared at W14. f) Adverse events in the study treatment area and in predefined diagnostic areas.;Timepoint(s) of evaluation of this end point: weeks 2,4,6 and 14 | — |
