Background and study aims
Actinic keratosis (AK) is a common pre-cancer (with increased risk of developing into cancer) skin change that is caused by due to sun exposure over many years with no sun protection. AK appears as patches of thick, scaly, or crusty skin that feel rough or dry. Several treatments are available for this skin condition. Photodynamic therapy (PDT) using a photosensitizer (a drug that is activated only in the areas of AK using a special type of light), can cure AK patches. After PDT has cleared the AK, patients must protect their skin from the sun to prevent AK coming back. In this study (called ATHENA), we want to test a cream containing sunscreen and piroxicam (a drug that can reduce the risk of skin cancer) in comparison to standard sunscreen-only products in preventing AK coming back after PDT.
Who can participate?
Adults who have at least 6 patches of AK on their scalp or face.
What does the study involve?
All patients will be treated with PDT. They will be randomly allocated to apply to either sunscreen alone or sunscreen containing piroxicam to the affected area twice daily for 6 days.
What are the possible benefits and risks of participating?
If the piroxicam-containing sunscreen is more effective than sunscreen alone in preventing AK coming back, then the participants in this group will benefit from a reduced need for PDT, which can be time-consuming and painful. The standard prevention is to use sunscreen, so participants in the sunscreen-only group will not receive worse treatment than if they were not in the study. There is no increased risk of side effects for the sunscreen containing piroxicam.
Where is the study run from?
Erba-Rinaldi Hospital and DermoLaser Office Verona.
When is the study starting and how long is it expected to run for?
March 2017 to April 2018
Who is funding the study?
The study is funded by Cantabria Labs Difa Cooper, the company that makes the sunscreen containing piroxicam.

Scientific title | The ATHENA Trial: Actixicam after photo-dynamic therapy for multiple actinic keratosis lesions. A randomized open-label assessor-masked outcome evaluation superiority trial vs. standard care in actinic keratosis subjects after phtotodynamic therapies |
Study acronym | ATHENA |
Study objectives | After photodynamic therapy (PDT) for multiple actinic keratosis (AK), lesion photoprotection strategies (i.e. use of sunscreen) is mandatory in order to reduce actinic damage and recurrence of new lesions. Recurrence of new AK lesions after PDT are common after 6-9 months after PDT. A sunscreen cream (SPF50+) containing piroxicam 0.8% has shown to be effective in reducing AK lesions as a monotherapy. There are no data comparing different photoprotection strategies (i.e sunscreen only, sunscreen with photolyase etc) comparing the efficacy in reducing AK recurrence after PDT. In this study, we wanted to assess if the use of SPF50+ and piroxicam cream could be more effective than standard photoprotection in reducing recurrence of AK after successful PDT. |

Intervention | Randomization was performed using a randomization list with an allocation ratio of 1:1. Actixicam: sunscreen SPF50+ and piroxicam 0.8% cream formulation, applied twice daily 0.5 g (1 finger tip unit) per application for 6 consecutive days after successful PDT Sunscreen: sunscreen cream (SPF50+ or SPF100+ and photolyase) applied twice daily 0.5 g (1 finger tip unit) per application for 6 consecutive days after successful PDT |
