Evaluating the Efficacy of NeoThelium FT in the Treatment of Venous Leg Ulcers

This is a randomized controlled trial evaluating the efficacy of NeoThelium FT in conjunction with standard of care vs. standard of care alone in treating venous leg ulcers.

This research will take place across multiple medical centers, where both researchers and participants will know which treatment is being used (open label). Patients who agree to participate and meet the study requirements during screening will be randomly assigned to one of two groups: either standard of care alone, or standard of care plus NeoThelium FT. As this is a post-marketing study, it will gather information about how effective the treatment is in treating venous leg ulcers. All subjects will complete two week screening phase prior to being randomized into a treatment arm. Treatment arms will consist of NeoThelium FT in conjunction with standard of care, vs. standard of care alone. The primary endpoint will be the percentage of target ulcers that achieve complete wound closure within 16 weeks. Secondary endpoints consist of wound area reduction rates, time to closure, follow-up closure, and pain assessment.

3. Subject has a Venous Leg Ulcer present for 4 weeks or greater (documented in medical record), and less than 12 months duration if being treated with continuous SOC
4. Subject has a Venous Leg Ulcer with a historical wound measurement showing less than 50% healing in 30 days prior to randomization
5. Subject has a Venous Leg Ulcer with screening wound measurement showing less than 25% healing in 14 days prior to randomization
