Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The study is a basic science research study that is designed to characterize and compare the immune response in individuals who are designated as ABO blood group secretors, meaning they have a functional copy of the FUT2 gene versus those patients who are designated ABO non-secretors after application of topical imiquimod to these patients.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Main cohort

This is a split-body study, with patients acting as their own controls between lesional and nonlesional skin. All patients will apply imiquimod.

Imiquimod

Intervention Type DRUG

Patients with a diagnosis of actinic keratosis or warts that would be prescribed imiquimod as standard of care will be asked to apply 2 packets (or 2 full pumps) of imiquimod once daily before bedtime for two weeks and then leave on overnight for \~8 hours.

(a) A biopsy will be performed at the baseline visit on the pre-treatment skin and the skin where the medication will not be applied. The skin where the medication will not be applied will act as the negative control. A biopsy will then again be performed on day 10 of imiquimod treatment on the treated skin only, where the study drug was applied.
