Plain English summary of protocol

Background and study aims
Actinic keratoses (AK) are dry scaly patches of skin caused by damage from years of exposure to sunlight. Photodynamic therapy (PDT) is a well-established treatment for AK that involves the use of a light-sensitive medication and a light source to destroy abnormal cells. After PDT sun-protection strategies are important in order to reduce the risk of new lesions and/or the need for more PDT. A film-forming medical device containing photolyase, a DNA-repairing enzyme with a light-protective action, has been developed (called Ery). The aim of this study is to assess the clinical effects of Ery in comparison with a commercially available sunscreen (SS) in AK patients after successful PDT for the treatment of AK lesions of the scalp.

Who can participate?
AK patients with at least five AK lesions on the scalp.

What does the study involve?
Participants are randomly allocated to be treated with either Ery or SS. The number of new AK lesions and the need to perform more PDT are evaluated at 1, 3 6 and 9 months after PDT.

What are the possible benefits and risks of participating?
The study products may help in reducing the risk of developing new AK lesions. No specific risks are associated with the use of the two products.

Where is the study run from?
IFO - Regina Elena - San Gallicano Hospital Dermatology and Oncology Division (Italy)

When is the study starting and how long is it expected to run for?
January 2014 to February 2015
