In this contralateral/bilateral study design, each patient served as his/her own control. One side of the face or scalp (Side B), the traditional control regimen of PDT was given (1 h topical drug then 16 min 40 sec of blue light). On the test side (Side A), we administered a new regimen; topical drug was applied and then the blue light immediately started. Three groups of patients (Study arms) had different times of exposure (either 30 min, 45 min, or 60 min). For all patients, the post-treatment course was compared for Sides A vs. B. The primary endpoints were pain during illumination, and lesion clearance at 3 months post-therapy.'}, 'enrollmentInfo': {'type': 'ACTUAL', 'count': 23}}, 'statusModule': {'overallStatus': 'COMPLETED', 'startDateStruct': {'date': '2014-04', 'type': 'ACTUAL'}, 'expandedAccessInfo': {'hasExpandedAccess': False}, 'statusVerifiedDate': '2023-10', 'completionDateStruct': {'date': '2018-12', 'type': 'ACTUAL'}, 'lastUpdateSubmitDate': '2023-10-09', 'studyFirstSubmitDate': '2014-04-25', 'studyFirstSubmitQcDate': '2014-04-25', 'lastUpdatePostDateStruct': {'date': '2023-10-10', 'type': 'ACTUAL'}, 'studyFirstPostDateStruct': {'date': '2014-04-28', 'type': 'ESTIMATED'}, 'primaryCompletionDateStruct': {'date': '2016-10', 'type': 'ACTUAL'}}, 'outcomesModule': {'primaryOutcomes': [{'measure': 'AK clearance', 'timeFrame': 'at 3 months post-treatment', 'description': 'The primary endpoint is treatment efficacy (AK lesion clearance at 3 months).
