Brief Summary

This trial is a multicenter, randomized, controlled study designed to evaluate the safety and efficacy of BioREtain® Amnion Chorion (BR-AC) plus standard of care versus standard of care only in the treatment of diabetic foot ulcers. The trial design will control potential variables that may affect the outcome between the treatment group and the control group by standardizing the requirements for debridement, wound dressings, and off-loading. Weekly subject visits will help monitor compliance in wound care and off-loading, as well as to document when wound closure is achieved. The study will also implement the use of an electronic imaging and measurement device using a standardized protocol to ensure the measuring of the wound surface area and volume is accurate, highly reproducible, and minimally variable. There will also be a crossover treatment phase for those patients that were relegated to standard care only. After their 12-week standard of care treatment phase and for only those subjects that did not achieve complete wound closure, will be allowed to crossover for an additional 12 weeks of treatment with the BR-AC product following the protocol and procedures set forth within this document.

Outcome Measures

Primary Outcomes (1)

• To determine whether DFUs treated with standard care plus BR-AC results in a higher probability of achieving complete wound closure compared to standard care alone.

  Percentage of subjects with complete wound closure over the 12-week treatment period, defined as 100% reepithelialization of the wound without drainage, where healing has been confirmed at two visits two weeks apart.

  over the 12-week treatment period

Secondary Outcomes (5)

• To compare differences between treatment groups in proportions of wounds with complete wound closure, based on time in days to closure.

  over the 12-week treatment period

• To compare differences between treatment groups in percent change in wound area (cm2).

  at 12 weeks

• To compare differences between treatment groups in percent change in wound volume (cm3).

  at 12 weeks

• To determine the total number of applications of BR-AC needed to achieve complete wound closure.

  over 12-weeks post-randomization

• To determine whether subjects that crossover and receive standard care plus BR-AC results in a higher probability of achieving complete wound closure over the 12 additional weeks versus standard care alone.

  over an additional 12 weeks

Other Outcomes (2)

• DFUs that acquire clinical signs and symptoms of infections post-randomization

  over 12-weeks post-randomization

• Proportion of subjects experiencing adverse events, by treatment group

  over the 17-week study period

Study Arms (2)

BR-AC plus Standard Care

EXPERIMENTAL

All subjects in the treatment group will receive sponsor-approved standard of care. Standard of care is defined as: * Debridement, * Wound cleansing with a neutral, non-irritating and non-toxic solution, * Non-adherent wound contact layer, a foam pad, alginate or hydrofiber dressing for moderately draining wounds, a secondary retention bandage, and * An off-loading device. Using an appropriate size to cover the entire wound area, BR-AC should be applied directly to the wound surface following sharp debridement w. It is recommended that the product be trimmed to fit the area of the wound with sterile scissors before application.

Other: BR-AC

Standard Care

PLACEBO COMPARATOR

All subjects in the control group will receive sponsor-approved standard of care. Standard of care is defined as: * Debridement, * Wound cleansing with a neutral, non-irritating and non-toxic solution, * Non-adherent wound contact layer, a foam pad, alginate or hydrofiber dressing for moderately draining wounds, a secondary retention bandage, and * An off-loading device.

Other: Standard Care

Interventions

BR-AC OTHER

BR-AC is an amnion layer, intermediate layer, and chorion layer placental membrane processed together with no separation of the layers. BR-AC is manufactured by BioStem Technologies, Inc. and is processed by the bioREtain method which, briefly, includes initial disinfection, processing with isotonic solutions, dehydration at 37-40°C and electron beam sterilization.

BR-AC plus Standard Care

Standard Care OTHER

Standard of care is defined as: * Debridement, * Wound cleansing with a neutral, non-irritating and non-toxic solution, * Non-adherent wound contact layer, a foam pad, alginate or hydrofiber dressing for moderately draining wounds, a secondary retention bandage, and * An off-loading device.
