Title: A Randomized, Blinded, Multicenter Study to Evaluate the Efficacy and Safety of Polidocanol Injectable Foam 0.5%, 1.0%, or 2.0% Compared to Vehicle for the Treatment of Saphenofemoral Junction (SFJ) Incompetence
Brief Summary: Varicose veins are enlarged, noticeably bulging veins, which commonly occur in the legs and may cause discomfort. In this study, patients with varicose veins in the legs will be participating. The purpose of this research study is to evaluate the safety and effectiveness of three different concentrations of an investigational drug, polidocanol injectable foam compared to vehicle (inactive solution) in treating the symptoms and appearance of varicose veins.
