About

This is a randomized, double-blind, placebo-controlled, phase II, multi-centered study to evaluate the efficacy and safety of ENERGI-F703 GEL in subjects who are ≥ 20 years old with venous leg ulcer (VLU). Subjects will be recruited from multiple sites in Taiwan. The treatment period will be 84 days with another 84-day follow-up period.

Sex: All

Ages: 20 to 85 years old

Volunteers: No Healthy Volunteers

3. With poor nutritional status (albumin < 2g/dl), poor diabetic control (HbA1c > 12%), a leukocyte counts < 2,000/mm3, abnormal liver function (AST, ALT>3 × upper limit of normal range) tests within 14 days prior to Screening visit or 28 days prior to Randomization visit

4. Requiring treatment with chemotherapeutic agents

5. With known or suspected hypersensitivity to any ingredients of IP and matched vehicle

6. With coronary heart disease with myocardial infarction, coronary artery bypass graft (CABG), or percutaneous transluminal coronary angioplasty (PTCA) within 3 months prior to Screening visit

7. (1) Female subject of childbearing potential who:
