This study examines a patient population with a non-healing, non-infected venous leg ulcer (VLU) having adequate arterial perfusion with confirmed venous reflux. It is hypothesized that weekly applications of the human placental allograft BioREtain® Amnion Chorion (BR-AC) applied to a non-healing VLU will result in a higher proportion of wounds showing complete healing within 12 weeks of initiating therapy, compared to standard care alone.
This study has a crossover period, where subjects on standard care alone who do not achieve complete healing within 12 weeks of initiating therapy will be allowed to crossover to receive BR-AC over 12 additional weeks, to evaluate if their wound can achieve complete healing.
Patient has signed the informed consent form.
Male or female patient at least 18 years of age or older, as of the date of the screening visit.
Has a VLU between the knee and ankle (at or above the malleoli), with a surface area in the range of ≥ 2.0 cm2 and ≤ 20.0 cm2 when measured by the investigator staff at the screening visit using the eKare device post debridement.
If the subject presents with > 1, but ≤ 3 VLU on the same leg, the largest ulcer will be selected as the target ulcer.
A target ulcer of non-venous etiologies (e.g., sickle cell anemia, necrobiosis lipoidica diabeticorum, pyoderma gangrenosum, vasculopathic or vasculitic).
Acute Deep Vein Thrombosis (DVT), defined as the first 10 days from onset of symptoms, or any DVT for which compression is considered by the Investigator to be contraindicated.
Clinical evidence of ulcer bed infection, or infected hardware.
Documented history of osteomyelitis at the target ulcer location within six (6) months preceding the screening visit.
