Further study details as provided by Northwestern University:

Primary Outcome Measures:
  • Live blinded rater and blinded photo rater analysis of areas at week 0 and week 6 for erythema, edema, crusting, ulceration, palpability, need to cease/delay treatment, and overall response in reduction of number of actinic keratoses (AKs). [ Time Frame: 6 weeks ]

Secondary Outcome Measures:
  • Subjects will assess pain, burning and itching on a scale of 0-3 at week 0, during retinoid treatment, during photo-therapy, one day after, and week 6. Also, principal investigator will evaluate adverse events at week 6. [ Time Frame: 6 weeks ]

Estimated Study Completion Date: December 2017
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
