Trial Outcomes & Findings for Bioequivalence Study of Two Imiquimod Cream 5% (NCT NCT00828568)

NCT ID: NCT00828568

Last Updated: 2014-01-28

Results Overview

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.

PRIMARY outcome

Timeframe: 24 weeks

Population: Intention to Treat (ITT) Population

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.

SECONDARY outcome

Timeframe: 24 weeks

Population: Safety group includes all patients who received a single dose

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.
