Comparison of the Efficacy and Tolerability of Solaraze for 3 Versus 6 Months in Patients With Mild to Moderate Actinic Keratosis Located on the Face and Head
- Registration Number
- NCT00204542
- Lead Sponsor
- University Hospital Tuebingen
- Brief Summary
Topical treatment of mild to moderate actinic keratosis located on the face and head with Solaraze® is known to be a safe and efficient treatment option. However, it is unclear if an expansion of the treatment period to 6 months will increase the rate of complete responses.
Therefore the investigators will evaluate the efficacy and safety of the treatment of actinic keratosis with Solaraze® applied twice daily to the face and head over 3 or 6 months of treatment.
