What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests new treatments for individuals with diabetic foot ulcers and venous leg ulcers. It compares special placental tissue products, such as Amnion-Chorion-Amnion and Amnion-Intermediate-Chorion, to standard care (regular cleaning and bandaging) to determine which is more effective for healing these wounds. Individuals who have had their ulcer for at least four weeks without much improvement might be suitable for this study. Participants will receive weekly treatments for up to 12 weeks or until their ulcer heals. As a Phase 4 trial, this study involves treatments that are already FDA-approved and proven effective, aiming to understand how they can benefit more patients.

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 is the safety track record for these treatments?

Research has shown that using amniotic and chorion tissues in treatments has been safe in past studies. For the Amnion-Intermediate-Chorion (AIC) treatment used on diabetic foot ulcers (DFUs), studies have found that these tissue products are well-tolerated and help ulcers heal faster with fewer complications than traditional treatments.

For venous leg ulcers (VLUs), similar positive results have been observed. Research indicates that the AIC treatment is safe, does not cause significant side effects, and supports ulcer healing.

The Amnion-Chorion-Amnion (ACA) treatment has also demonstrated promising safety results. In studies with DFUs and VLUs, this treatment has been linked to a good safety record. Patients did not report serious side effects, and the treatment helped ulcers heal more quickly than standard care alone.

These findings suggest that both AIC and ACA treatments are generally safe for treating these types of ulcers. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Researchers are excited about these treatments for diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs) because they use innovative placental tissue products. Unlike standard care options that focus on cleaning, debridement, and moisture balance, these treatments incorporate Amnion-Chorion-Amnion (ACA) and Amnion-Intermediate-Chorion (AIC) sheets derived from human placental tissue, which provide a unique biological scaffold that may enhance healing. The potential of these treatments lies in their ability to deliver a complex mix of proteins and growth factors directly to the wound site, potentially accelerating closure and improving outcomes compared to traditional methods.

What evidence suggests that this trial's treatments could be effective for diabetic foot and venous leg ulcers?

This trial will compare the effectiveness of different treatments for diabetic foot ulcers (DFUs) and venous leg ulcers (VLUs). Participants may receive either Amnion-Intermediate-Chorion (AIC) or Amnion-Chorion-Amnion (ACA) treatments, both utilizing layers of amnion and chorion tissue. Research has shown that these treatments effectively heal DFUs and VLUs. Specifically, studies indicate that for DFUs, these treatments lead to faster healing compared to standard care, with over 90% of wounds remaining closed long-term. For VLUs, similar success has been observed, with some trials reporting up to 75% of difficult-to-heal wounds closing within 12 weeks. These treatments promote quicker wound healing and sustained closure, offering hope for those with chronic ulcers. ^{4 6 7 8 9}

Group IV: ACA for DFUs Experimental Treatment 2 Interventions

Participants with a diabetic foot ulcer (DFU) will receive treatment with an Amnion-Chorion-Amnion sheet allograft product, a dehydrated trilayer human placental tissue derived from donated human tissue, and weekly treatment with standard of care (cleaning, debridement, ulcer moisture balance, and offloading) until ulcer closure, or a maximum of 12 weeks, whichever occurs first.

Published Research Related to This Trial

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 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.

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.

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.

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 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.
