A phase 3, randomized, parallel, multicenter, double-blind, placebo-controlled study to investigate efficacy and safety of KP-001 in patients aged >=2 years with common venous malformations, common lymphatic malformations, or KTS/CLOVES syndrome

The purpose of this study is to measure the efficacy and safety of KP-001 compared with placebo in patients aged >=2 years with common VM, common LM, or KTS/CLOVES syndrome. An independent data monitoring committee (DMC) will be established to determine whether to discontinue or continue the study. It will also determine the redesign of the number of cases based on the result of the interim analysis.
