A Study to Evaluate the Safety and the Efficacy of EscharEx (EX-02 Formulation) in Debridement of Venous Leg Ulcers

Study Summary

This study is a multicenter, prospective, randomized, placebo controlled, adaptive design study performed to assess the safety and the efficacy of 5% EscharEx (EX-02) compared to Gel Vehicle (placebo) and non-surgical standard of care (NSSOC), in debridement of Venous Leg Ulcers (VLU) (in a ratio of 2:2:1) in debridement of VLU. The main objective of this study is: To assess the safety and the efficacy of EscharEx (EX-02 formulation) compared to Gel Vehicle (placebo) and non-surgical standard of care (NSSOC), in debridement of Venous Leg Ulcers (VLU). 120 randomized adult patients with VLU that fail to heal for 4 weeks to 2 years, and with \>50% non-viable tissue (necrotic/slough/fibrin) on the VLU. The maximum number of patients to be enrolled is 160. The total duration of the study of each participating subject is up to 17 weeks: screening (1 week) + Daily visit period (up to 2 weeks) + Twice-weekly visits period (2 weeks) + Weekly visits period (10 weeks) + closure confirmation (up to 2 weeks, if applicable). Each patient will go through 4 periods during the trial: 1. Screening period (2 visits, 7 \[+2\] days apart). Including: recording demographics, medical history and concomitant medications, vital signs, physical examination, clinical laboratory tests, wound photography and assessments and questionnaires (pain, wound status and QoL). During this period, wounds will be treated by standard treatment (e.g. appropriate dressing, compression bandage) per investigator discretion, with the exclusion of mechanical and surgical debridement. During the one week screening period, patients whose wound size (surface area, as measured by eKare inSightTM) decreases by more than 20 percent will be excluded. 2. Daily visits period (up to 8 daily site visits within up to 14 days): During the Daily visit period, the patient will arrive daily to site visits. During each visit, adverse events, concomitant medication, vital signs and pain will be recorded, the wound will

Primary Outcome

The clinical assessor will define complete debridement, after each application during the daily visits period
