Comparing two treatments for non-healing venous leg ulcers

A Randomized Controlled Clinical Trial Evaluating The Efficacy of an Amnion Membrane Allograft Intended for Use in the Management of Non- Healing Venous Leg Ulcers Versus Standard Of Care Alone

This study is testing whether a new type of dressing made from amniotic tissue works better than a collagen dressing for helping people with stubborn leg ulcers heal.

What this trial studies

This clinical evaluation aims to compare the effectiveness of E-GRAFT™, a dehydrated amniotic allograft, against FIBRACOL™, a collagen alginate dressing, in managing non-healing venous leg ulcers. Participants will receive standard of care treatment alongside one of the two dressings, and the study will assess the rate of wound closure, changes in ulcer size over 12 weeks, and any adverse events. The primary endpoint is the percentage of patients achieving complete closure of their target ulcer, while secondary endpoints include pain levels and infection occurrences.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with venous leg ulcers that have not healed after at least 4 weeks of standard care.

Not a fit: Patients with ulcers that probe to bone or those with inadequate circulation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients suffering from non-healing venous leg ulcers.

How similar studies have performed: Other studies have shown promise in using amniotic allografts for wound healing, suggesting potential success for this approach.

Eligibility criteria

Inclusion Criteria:

1. Subjects must be at least 18 years of age or older.
2. At randomization subjects must have a target ulcer with a minimum surface area of 1.0 cm2 and a maximum surface area of 20.0 cm2 measured post debridement with manual measure.
3. The target ulcer must have been present for a minimum of 4 weeks and a maximum of 52 weeks of standard of care prior to the initial screening visit.
4. If the subject has two or more ulcers, they must be separated by at least 2 cm. The largest ulcer satisfying the inclusion and exclusion criteria will be designated as the target ulcer.
5. The subject must consent to using the prescribed off-loading method for the duration of the study.
6. The subject must agree to attend the weekly study visits required by the protocol.
7. The subject must be willing and able to participate in the informed consent process.
8. The target ulcer must be full thickness on the foot or leg that does not probe to bone.
9. Adequate circulation to the affected foot as documented by any of the following methods performed within 3 months of the first screening visit:

   1. TCOM ≥30 mmHg
   2. ABI between 0.7 and 1.3
   3. PVR: Biphasic
   4. TBI ˃0.6
   5. As an alternative, arterial Doppler ultrasound can be performed evaluating for biphasic dorsalis pedis and posterior tibial vessels at the level of the ankle
10. If the subject has two or more ulcers, they must be separated by at least 2 cm. The largest ulcer satisfying the inclusion and exclusion criteria will be designated as the target ulcer.
11. Target ulcers must have been treated with compression therapy for at least 14 days prior to randomization.

Exclusion Criteria:

1. A subject known to have a life expectancy of \< 6 months is excluded.
2. If the target ulcer is infected or if there is cellulitis in the surrounding skin, the subject is excluded.
3. Presence of osteomyelitis or exposed bone, probes to bone or joint capsule on investigator's exam or radiographic evidence.
4. Index ulcer and/or index ulcer limb may have had prior infection(s), but infection(s) must be adequately treated and controlled
5. A subject receiving immunosuppressants (including systemic corticosteroids at doses greater than 10 mg of Prednisone per day or equivalent) or cytotoxic chemotherapy is excluded.
6. The topical application of steroids to the ulcer surface within one month of initial screening is not permitted.
7. A subject with a previous partial amputation on the affected leg is excluded if the resulting deformity impedes proper offloading of the target ulcer.
8. If a subject is diabetic and has a glycated hemoglobin (HbA1c) greater than or equal to 12% taken at or within 3 months of the initial screening visit he/she is excluded.
9. If a subject has a serum creatinine ≥ 3.0mg/dL within 6 months of randomization he/she is excluded.
10. The subject is excluded if the surface area measurement of the target ulcer has reduced in size by more than 30% in the 2 weeks prior to the initial screening during the 2-week screening phase: the 2 weeks from the initial screening visit (SV1) to the TV1/randomization visit during which time the subject received SOC.
11. Women who are pregnant or considering becoming pregnant within the next 6 months are excluded.
12. A potential subject with end stage renal disease requiring dialysis is excluded.
13. A subject who, in the opinion of the Investigator, has a medical or psychological condition that may interfere with study assessments is excluded.
14. A subject treated with hyperbaric oxygen therapy or a Cellular and/or Tissue Product (CTP) in the 30 days prior to the initial screening visit is excluded
