Item 8.01 Other Events.

DUSA Pharmaceuticals, Inc.^® (NASDAQ GM: DUSA), is reporting preliminary results of a Phase 2 clinical trial investigating the use of the Levulan^® Kerastick^® in conjunction with BLU-U^® blue light illumination for the treatment of actinic keratoses (AKs) of the face and scalp when utilizing short drug incubation. The study demonstrated that treatment with Levulan Kerastick — after incubating for one, two or three hours — resulted in a statistically significant number of patients with complete lesion clearance and a statistically significant reduction in AK lesion count when compared to treatment with vehicle 12 weeks post treatment.

The multi-center, randomized, blinded, vehicle-controlled study across 13 trial sites enrolled a total of 235 subjects and followed them for up to six months. The results showed that at 12 weeks, after receiving up to 2 photodynamic therapy (PDT) treatments, subjects treated with Levulan^® using incubation times of 1, 2, or 3 hours all demonstrated similar degrees of efficacy, with up to 79% AK lesion clearance rates, while subjects receiving vehicle alone had up to a 14% lesion clearance. Analysis of the 24 week follow up data showed that up to 78% of subjects treated using broad area, short drug incubation (BASDI) who were completely clear of AK lesions at 12 weeks remained free of lesions at 24 weeks. This compares to 13% of subjects treated using a spot application method.

The safety profile seen in this study is consistent with what has been seen in previous clinical studies involving Levulan^® PDT and is similar to that seen in the current labeling. There were no treatment-related serious adverse events reported in the study and only one subject did not complete the study. The study utilized the Levulan^® Kerastick^® (aminolevulinic acid HCl) for Topical Solution, 20% with the BLU-U^® Blue Light Photodynamic Therapy Illuminator which is FDA approved for the treatment of minimally to moderately thick actinic keratoses (AKs) of the face or scalp.
