Primary | Number of Participants With 100% Clearance of Actinic Keratosis Lesions: Comparison of Taro Imiquimod 5% and Aldara-Imiquimod 5% | Uses per protocol (PP) population. Each patient is assessed at 24 weeks. Actinic keratosis (AK) lesions that were identified and measured at baseline are reevaluated at the conclusion of the study. If all lesions that were identified at baseline are no longer present and there are no new lesions, the patient is 100% clear of AK lesions. |
24 weeks | No |
Primary | Number of Participants in Intention-to-treat (ITT)Population With 100% Clearance of Actinic Keratosis (AK) Lesions Identified at Baseline | Uses ITT population. Three patients (1 Imiquimod 5% Taro and 2 Imiquimod Aldara) did not have a follow-up visit after dosing and were excluded from ITT. Three patients (2 Imiquimod 5% Taro and 1 Imiquimod Aldara) were not evaluable at the 24-week visit and were not in the analysis. Each patient is assessed at 24 weeks. Actinic keratosis (AK) lesions that were identified and measured at baseline are reevaluated at the conclusion of the study. If all lesions that were identified at baseline are no longer present and there are no new lesions, the patient is 100% clear of AK lesions. |
24 weeks | No |
Secondary | Patients Reporting at Least One Adverse Event | For all patients who received a single dose, adverse events were collected at each follow-up visit. Any patient reporting a single or multiple adverse events at any visit was conisdered to have had at least one adverse event. | 24 weeks | Yes |
