PRIMARY outcome

Timeframe: 17 weeks

Population: Group A = Levulan and Blu-U Light; Group B = Vehicle and Blu-U Light; Group C = Vehicle Only. Of the 30 randomized patients, 24 (80%) completed the entire study. 8 (80%) patients completed from Group A, 10 (100%) from Group B, and 6 (60%) from Group C.

The Investigator's global assessment (IGA) of rosacea is a subjective 7-point, static scoring system. Scores range from 0 to 6: 0 (clear), 1 (minimal), 2 (mild), 3 (mild to moderate), 4 (moderate), 5 (moderate to severe), 6 (severe).

The Inflammatory Lesion Investigator's Global Assessment (ILIGA) is a subjective 5-point measure of the overall disease severity. Scores range from 0 to 4: 0 (clear), 1 (almost clear), 2 (mild), 3 (moderate), 4 (severe).

SECONDARY outcome

Timeframe: 17 weeks

Population: Group A = Levulan and Blu-U Light; Group B = Vehicle and Blu-U Light; Group C = Vehicle Only. Of the 30 randomized patients, 24 (80%) completed the entire study. 8 (80%) patients completed from Group A, 10 (100%) from Group B, and 6 (60%) from Group C.

The Clinical Erythema Assessment (CEA) scale is an assessment of erythema. It has a score range from 0 to 4: 0 (none), 1 (mild), 2 (moderate), 3 (significant), 4 (severe). The total score is based on the evaluation of all areas of the face (forehead, chin, right cheek, left cheek, and nose). Each of these areas were scored from 0-4, giving a maximum total score of 20.

The Inflammatory Lesion Count (ILC) is calculated by the number of inflammatory lesions (papules, pustules, nodules) as recorded by the investigator.

SECONDARY outcome

Timeframe: 17 weeks

Population: Group A = Levulan and Blu-U Light; Group B = Vehicle and Blu-U Light; Group C = Vehicle Only. 8 (80%) patients completed from Group A, 10 (100%) from Group B, and 6 (60%) from Group C. One participant in Group B did not complete the POA scale at the last follow-up visit; therefore only 9 participants are included in the analysis for Group B.

For the Patient Overall Assessments (POA) scale, patients assessed the overall improvement of their rosacea using a 4-point scale, where 1 = excellent improvement, 2 = good/moderate improvement, 3 = no change, 4 = worsening.
