Chronic Venous Leg Ulcers
Conditions
Keywords
Chronic ulcers, Venous ulcers
Brief summary
The primary objective is to evaluate the clinical benefit of CureXcell® as adjunct to Standard of Care in the treatment of Chronic Venous Leg Ulcers. CureXcell® is a cell based therapy, containing activated homologous white blood cells prepared from donated healthy whole blood. A total of 252 patients will be randomized to receive either CureXcell® or Placebo.
Interventions
CureXcell® is a cell based therapy obtained from donated whole blood. The blood is collected from healthy young adults, the white blood cells are separated and then activated by hypo-osmotic shock.
Normal saline injected at each centimeter of ulcer bed

Eligibility
Inclusion criteria
* Ankle Brachial Pressure Index (ABI) ≥ 0.80 * Venous insufficiency confirmed by duplex Doppler ultrasound * Presence of a venous leg ulcer, unresponsive to Standard of Care treatment for at least 4 weeks and between ≥ 1 cm2 and ≤ 17.1 cm2 at screening; and between ≥ 1 cm2 and ≤ 12cm2 at the Baseline Visit
Exclusion criteria
* Target Ulcer has decreased \>30% in size from Screening to Baseline * Documented history of osteomyelitis at the Target Ulcer location within 6 months preceding the Baseline Visit. * Patients who are unable to tolerate multi-layer compression therapy. * Ulcer, which in the opinion of the Investigator is suspicious for cancer. * Any malignancy within the past 5 years, excluding successfully treated basal cell carcinoma or squamous cell carcinoma without evidence of metastases. * History of radiation at the Target Ulcer site in previous 12 months prior to Baseline Visit. * Patients with clinically significant claudication * Current sepsis * Patients with known history of significantly compromised immunity for any reason including radiation therapy, chemotherapy or HIV
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Time to complete closure of Target Ulcer | up to 16 weeks | Time to complete closure of Target Ulcer at any time during the 12-week Treatment Phase. Complete closure is confirmed at two consecutive study visits two weeks apart. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Proportion of complete closure of Target Ulcer | up to 16 weeks | Proportion of complete closure of Target Ulcer within the Treatment Phase. Complete closure is confirmed at two consecutive study visits two weeks apart. |
| Percentage change from baseline in Target Ulcer surface area | up to 12 weeks | Percentage change from baseline in Target Ulcer surface area at the end of the Treatment Phase. |
| Proportion of Target Ulcer recurrence | up to 24 weeks | Proportion of Target Ulcer recurrence during the 12-week Follow-Up Phase. |
Other
| Measure | Time frame | Description |
|---|---|---|
| Adverse Events | up to 24 weeks | Incidence of adverse events, including overall AEs, AEs related to the CureXcell® and study-ulcer-associated AEs. |
