Trial Summary

What is the purpose of this trial?

The purpose of this study is to determine how well multiple CAMPs (Cellular, Acellular and Matrix-Like Products) and Standard of Care work when compared to Standard of Care alone in achieving complete closure of diabetic foot and venous leg ulcers.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications. However, if you are on immunosuppressants, high-dose corticosteroids, or certain chemotherapy drugs, you may not be eligible to participate.

What data supports the effectiveness of the treatment Amnion-Chorion-Amnion and related products for diabetic foot and venous leg ulcers?

Research shows that dehydrated human amnion/chorion membrane (dHACM) allografts significantly improve healing rates in diabetic foot ulcers compared to standard care, with studies reporting higher complete healing rates and faster time to healing. Additionally, dHACM has been effective in reducing pain and improving wound healing in chronic leg ulcers of various causes. ^{1 2 3 4 5}

Is the use of amnion/chorion membrane products safe for treating wounds?

Research shows that amnion/chorion membrane products, like dehydrated human amnion/chorion membrane (dHACM), are generally safe for use in humans. Studies have reported successful wound healing with minimal complications, suggesting these products are safe for treating various types of wounds. ^{4 6 7 8 9}

How does the treatment for diabetic foot and venous leg ulcers differ from other treatments?

This treatment uses dehydrated human amnion/chorion membrane allograft (dHACM), which is derived from the placenta and has shown promise in healing chronic ulcers by promoting faster wound closure and reducing pain. Unlike standard care, dHACM is applied weekly and has been found to significantly improve healing rates and reduce pain in both diabetic foot and venous leg ulcers. ^{1 2 3 4 5}

Findings from Research

In a study comparing dehydrated human amnion and chorion allograft (dHACA) to standard care for chronic diabetic foot ulcers, 70% of wounds treated with dHACA healed at 6 weeks, compared to only 15% with standard care.

At 12 weeks, dHACA treatment resulted in 85% healing of wounds, significantly faster than the 25% healing rate in the standard care group, demonstrating its efficacy in promoting wound closure.

In a clinical trial involving 110 patients with chronic lower extremity ulcers, those treated with dehydrated human amnion/chorion membrane allograft (dHACM) showed a significantly higher complete healing rate (70% vs. 50%) compared to those receiving standard care over 12 weeks.

Patients receiving dHACM not only healed faster but were also more than twice as likely to achieve complete healing within the study period, indicating its efficacy as a treatment for diabetic ulcers.

In a study of 218 patients with diabetic foot ulcers, treatment with a bioengineered living cellular construct (BLCC) resulted in a significantly faster healing time (median 13.3 weeks) compared to a dehydrated human amnion/chorion membrane allograft (dHACM) which took 26 weeks.

Patients treated with BLCC had a higher healing rate, with 72% healed by 24 weeks compared to 47% for dHACM, indicating that BLCC is nearly twice as effective in promoting healing of diabetic foot ulcers.

In a randomized controlled trial involving 60 subjects with nonhealing diabetic foot ulcers, dehydrated human amnion and chorion allograft (dHACA) demonstrated a significantly faster healing time compared to the tissue-engineered skin substitute (TESS), with mean healing times of 32 days for dHACA versus 63 days for TESS at 12 weeks.

The dHACA group also showed a higher healing rate of 90% compared to 40% for the TESS group, and it was more cost-effective, with an average cost of $2,200 for dHACA compared to $7,900 for TESS.

In a case series of six patients with chronic lower leg ulcers, the use of dehydrated human amnion/chorion membrane allograft (dHACM) once a week for 5 weeks led to effective pain reduction and improved wound healing in three patients with different ulcer causes.

The study suggests that pain reduction observed after 1 to 2 applications of dHACM can predict a favorable healing response, which may help clinicians decide whether to continue or discontinue treatment, potentially reducing costs.

A 22-year-old female trauma patient with severe soft tissue loss and exposed bone successfully received four applications of dehydrated human amnion/chorion membrane (dHACM), which stimulated robust granulation tissue formation over her wounds.

The use of dHACM was crucial in preparing the wounds for skin grafting, ultimately contributing to limb salvage and a positive surgical outcome where traditional methods had failed.

In a study of 117 patients treated with dehydrated human amnion/chorion membrane (dHACM) allografts over 2 years, 91.1% achieved complete healing of their nonhealing wounds, demonstrating the efficacy of this treatment.

dHACM was effective for various types of wounds, including diabetic foot ulcers and venous leg ulcers, with an average of 5.1 weekly applications needed for healing, indicating its potential as a versatile option in advanced wound care.

In a study of 21 patients undergoing lower extremity surgery, the use of dehydrated human amnion and chorion allograft (dHACA) significantly improved post-treatment AOFAS scores from 35.8 to 87.5, indicating enhanced overall function and reduced pain.

The application of dHACA was associated with fewer wound complications, including no instances of wound dehiscence, suggesting it may be a beneficial adjunct in foot and ankle surgical procedures.

The study confirmed that PURION® processed dehydrated human amnion/chorion tissue allografts (dHACM) retain significant biological activities, including the presence of various growth factors and interleukins that promote wound healing, as demonstrated through enzyme-linked immunosorbent assays (ELISA).

In both in vitro and in vivo experiments, dHACM was shown to stimulate human dermal fibroblast proliferation and recruit mesenchymal stem cells to the site of implantation, indicating its potential effectiveness in enhancing wound healing through a paracrine mechanism.
