Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Subject Recurrence Rate | Month 12 | percentage of subjects who had achieved 100% clearance at Visit 6 (Week 12) in CP0108, that have one or more previously treated (as part of CP0108) AK lesion(s) present in the Treatment Area at any visit during CP0108A follow-up |
| Duration of Response | one year | the time from Week 12 (in the DUSA-CP0108 study) to the visit at which a previously treated and cleared lesion recurs. If a subject begins or receives treatment for previously cleared AK lesions in the Treatment Area between scheduled visits, the date the treatment started will be the end of treatment response, or, if the start date is unknown, the visit prior to starting the new treatment will be the end of treatment response. |
| Lesion Recurrence Rate | Month 12 | the proportion of lesions that were CR at Week 12 in CP0108 that are visible or palpable at Visit 10, will be determined for all ALA-PDT treated subjects who have at least one AK designated as clear at Week 12 in the DUSA-CP0108 study. |
| Duration of Lesion Response | one year | the time from Week 12 (in the DUSA-CP0108 study) to the visit at which the AK lesion recurs for all ALA-PDT treated subjects who have at least one AK designated as clear at Week 12 in the DUSA-CP0108 study. If a previously cleared lesion receives treatment between scheduled visits, the date the treatment started will be the end of treatment response for that lesion, or, if the start date is unknown, the visit prior to starting the new treatment will be the end of treatment response. |

| Scaling & Dryness | Baseline | SCALING AND DRYNESS SCALE Grade 0 = None Grade 1 = Minimal - barely perceptible desquamation Grade 2 = Mild - limited areas of fine desquamation in up to 1/3 of the treatment area Grade 3 = Moderate - fine desquamation involving 1/3 to 2/3 of the treatment area or limited areas of coarser scaling Grade 4 = Severe - coarser scaling involving more than 2/3 of the treatment area or limited areas of very coarse scaling |
| Hypopigmentation | Baseline | HYPOPIGMENTATION SCALE Grade 0 = No hypopigmentation Grade 1 = Light hypopigmentation involving small areas Grade 2 = Moderate hypopigmentation involving small areas; light hypopigmentation involving moderate areas Grade 3 = Moderate hypopigmentation involving moderate sized areas; light hypopigmentation involving large areas; small areas of marked hypopigmentation |
| Erythema | Baseline | Erythema Scale - Grade 0 = None Grade 1 = Minimal - barely perceptible erythema Grade 2 = Mild - predominantly minimal erythema (pink) in the treated area with or without a few isolated areas of more intense erythema Grade 3 = Moderate - predominantly moderate erythema (red) in the treated area with or without a few isolated areas of intense erythema (bright red) Grade 4 = Severe - predominantly intense erythema (bright red) in the treated area with or without a few isolated areas of very intense (fiery red) erythema |
| Edema | Baseline | EDEMA SCALE Grade 0 = None Grade 1 = Minimal - scant, rare edema Grade 2 = Mild - easily seen edema, minimally palpable, involving up to 1/3 of the treatment area Grade 3 = Moderate - easily seen edema and typically palpable, involving between 1/3 to 2/3 of the treatment area Grade 4 = Severe - easily seen edema, indurated in some areas, involving over 2/3 of the treatment area |
