Clinical Trial Summary

In this clinical one-site investigation the performance and safety of a skin preparation device will be evaluated for removing hyperkeratotic skin prior to further medical treatment. Comfort and pain during skin preparation, as well as performance and safety of device, will be compared to comparators on separate skin areas for every subject.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Grade of hyperkeratotic skin removal	Sufficient hyperkeratotic skin removal in comparison to comparative methods. The removal of hyperkeratotic skin is assessed visually and by palpation.; Removal of hyperkeratotic skin measurement grades: All hyperkeratotic skin removed, Partial hyperkeratotic skin removed, None hyperkeratotic skin removed.	Day 0
Secondary	Grade of injury to skin / grade of skin irritation / grade of allergic skin reaction	Investigator assessment of adverse effects on skin in comparison to the comparative methods.; Grade of injury to skin: none, mild, moderate, severe. Grade of skin irritation: none, mild, moderate, severe. Grade of allergic skin reaction: none, mild, moderate, severe.	Day 0
Secondary	Grade of skin irritation / grade of allergic skin reaction	Investigator assessment of adverse effects on skin in comparison to the comparative methods.; Grade of skin irritation: none, mild, moderate, severe. Grade of allergic skin reaction: none, mild, moderate, severe.	14 day follow-up
Secondary	Duration of operation time per treated skin area	Operation time assessed by the mean difference in time per treated skin area to remove the hyperkeratotic skin in comparison to comparative methods.	Day 0
Secondary	Presence of actinic keratosis	Presence of actinic keratosis (AK) is measured by number of different grades of AK lesions.; Number of different grades of AK lesions: None, Grade I AK lesions, Grade II AK lesions, Grade III AK lesions.	Day 0
Secondary	Clearance of actinic keratosis	Number of different grades of actinic keratosis (AK) lesions are measured: None, Grade I AK lesions, Grade II AK lesions, Grade III AK lesions.; Actinic keratosis clearance is assessed as the number of cleared actinic keratosis lesions at 4th month follow-up divided by the actinic keratosis lesion number at Day 0. Clearance will be reported in %. A high %-value means a high number of cleared lesions.	4th month follow-up
Secondary	Physician comfort during skin preparation using an investigator questionnaire	Rate of physician comfort when comparing the investigational product versus comparative methods. The endpoint will utilize a questionnaire for the investigator/nurse to fill in.	Day 0
Secondary	Subject comfort during skin preparation using a subject questionnaire	Rate of subject comfort (including skin sensation and heating of skin) when comparing the investigational product with comparative methods. The endpoint will utilize a questionnaire for the subject to fill in.; Skin sensation during skin preparation: Very pleasant, Pleasant, Neutral, Unpleasant, Very unpleasant.; Heating of skin during skin preparation: None, Mild temperature rise, Moderate temperature rise, High temperature rise, Burning.	Day 0
Secondary	Subject pain sensation during skin preparation	Rate of pain using visual analogue scale (VAS). VAS: 0 - 10 (0= No pain and 10 = worst possible pain)	Day 0
Secondary	Subject pain sensation during daylight photodynamic treatment	Rate of pain using visual analogue scale (VAS). VAS: 0 - 10 (0= No pain and 10 = worst possible pain)	Day 0
