Dose-Response Profile of A-101 in Subjects With Seborrheic Keratosis

Completed · Phase 2 · Has a placebo group

Conditions studied: Seborrheic Keratosis

In brief

The main objective of this study is to evaluate the dose-response relationship of two concentrations of A-101 solution when applied to individual seborrheic keratosis (SK) lesions (target lesions) compared with a matching A-101 Solution Vehicle.
