HM242-Solution vs Comparator

The objectives of this study include investigating the performance of HM242-Solution compared to normal Saline with respect to venous leg ulcer healing. Saline is widely used for venous leg ulcer cleansing and has served as comparator or standard treatment in clinical trials evaluating new cleansing products to prove that it is as good as the standard treatment. Data will also be collected on the patients' quality of life and any adverse events that may arise during the study.
