DUSA Pharmaceuticals, Inc.^®

, a dermatology company that is developing and marketing its Levulan^® (aminolevulinic acid HCl) Photodynamic Therapy (PDT) platform, today announced results of an investigational study designed to examine and compare the safety and efficacy of broad area application of the Levulan^® Kerastick^® with or without occlusive dressing (where the treatment area is covered or wrapped) in conjunction with the BLU-U^® for the treatment of minimally to moderately thick actinic keratoses (AKs) on the upper extremities. The study showed a statistically significant lesion reduction and complete clearance of actinic keratoses of the extremities (hands and arms) when compared to treatment with vehicle.  The use of occlusion resulted in a statistically significant improvement in lesion clearance rates compared to treatment without occlusion.
