Randomized, Double-Blind, Placebo-Controlled, Parallel-Cohort Study to Evaluate the Efficacy, Safety, Tolerability, and Pharmacokinetics of Once-Daily Application of Topical VDA-1102 Ointment for 28 Days in Subjects With Actinic Keratosis

This Phase 2 clinical trial is a multi-center, randomized, double-blind, placebo-controlled, multiple-dose, parallel-cohort study to assess the efficacy, safety and tolerability of VDA-1102 in the treatment of actinic keratosis (AK) on the head of male and female adult subjects.

Approximately 84 subjects who meet the study's enrollment criteria at the completion of the Screening Period will be randomized to receive 5% or 10% VDA-1102, or matched-placebo.
