Trial Summary

The trial does not specify if you need to stop taking your current medications, but you cannot participate if you are taking immunosuppressants, certain chemotherapy drugs, or hydroxyurea. It's best to discuss your specific medications with the trial team.

What data supports the effectiveness of the treatment ppLHACM for foot ulcers?

Research shows that using human amnion/chorion membrane, similar to ppLHACM, can help heal diabetic foot ulcers more effectively than standard care alone. Studies found that these membranes can speed up healing and reduce wound size, making them a promising treatment option. ^{1 2 3 4 5}

Is the use of human amnion/chorion membrane safe for treating foot ulcers?

Studies have shown that human amnion/chorion membrane, used under different forms like dehydrated or acellular, is generally safe for treating various types of ulcers and surgical wounds. It has been used without causing immune reactions or significant complications, and it may even reduce wound healing issues. ^{3 6 7 8 9}

How is the treatment ppLHACM different from other treatments for foot ulcers?

The treatment ppLHACM, which uses human amnion/chorion membrane, is unique because it has antimicrobial properties and does not trigger an immune response, helping to protect and heal wounds. It is derived from the placenta and contains growth factors and proteins that aid in healing, making it different from traditional skin substitutes. ^{1 3 4 10 11}

What is the purpose of this trial?

This study will evaluate two human amnion/chorion membrane (ppLHACM) products and Standard of Care (SOC) versus SOC alone in the closure of nonhealing diabetic foot ulcers (DFUs).

Treatment Details

Interventions

• ppLHACM

Trial Overview The trial is testing two treatments: EPIEFFECT and EPIXPRESS—both human amnion/chorion membrane products—alongside Standard of Care (SOC), compared to SOC alone in healing diabetic foot ulcers.

Participant Groups

Group I: EPIXPRESS Experimental Treatment 1 Intervention

EPIXPRESS™ is a PURION processed lyophilized human placental tissue allograft that includes the amnion layer, intermediate layer, and chorion layer of the amniotic membrane. The product is intended for use as a barrier to provide a protective environment in acute and chronic wounds. EPIXPRESS is fenestrated to help facilitate fluid movement and can be used on wounds that produce copious amounts of exudate.

Group II: EPIEFFECT Experimental Treatment 1 Intervention

EPIEFFECT® is a PURION processed lyophilized human placental tissue allograft that includes the amnion layer, intermediate layer, and chorion layer of the amniotic membrane. The product is intended for use as a barrier to provide a protective environment in acute and chronic wounds.

Group III: Standard of Care Active Control 1 Intervention

Standard of care will be cleaning, debridement, ulcer moisture balance, and offloading.

ppLHACM is already approved in United States for the following indications:

Findings from Research

Fetal membranes, specifically amnion and chorion, can be effectively used as biological dressings for treating various types of lower extremity ulcers, as demonstrated through multiple case histories.

The authors advocate for the broader adoption of fetal membranes in clinical practice, highlighting their potential benefits in enhancing healing for pedal ulcerations encountered by podiatrists.

In a pilot trial involving 31 participants with diabetic foot ulcers, the addition of dried human amniotic membrane (dHAM) to standard care showed a higher healing rate (27%) compared to standard care alone (6.3%) within 12 weeks, although the difference was not statistically significant (P = .1).

The dHAM group also demonstrated a significantly greater percentage reduction in wound area (P = .0057) with no difference in adverse events between the two groups, indicating that dHAM is a safe and potentially effective treatment for diabetic foot ulcers.

Amniotic membrane transplantation showed promising results in treating refractory chronic leg ulcers, with complete re-epithelialization achieved in one case by week 8 and an average wound size reduction of 81.93% by week 16 across four ulcers.

The treatment also significantly reduced pain intensity by 86.6% without any observed adverse effects, suggesting it is a safe and effective alternative for patients with difficult-to-treat ulcers.

The use of human amnion/chorion membrane in conjunction with standard therapy significantly improves healing rates for diabetic foot ulcers (DFUs), with a marked reduction in incomplete healing wounds compared to standard care alone, as shown in a meta-analysis of seven randomized controlled trials involving 352 initial studies.

Optimal assessment times for evaluating wound healing progress with amnion treatment are at 4 weeks and 12 weeks, indicating that early and later evaluations are crucial for understanding treatment efficacy.

In a study of 11 patients with chronic diabetic foot ulcers (DFUs) who did not heal with standard care, the addition of dehydrated human amniotic membrane (dHAM) treatment led to a significant increase in healing rates, with 91% achieving complete healing by 12 weeks.

Patients treated with dHAM showed an average wound size reduction of 87.6% after 4 weeks, compared to only 26.8% with standard care alone, indicating that dHAM can greatly enhance healing outcomes for difficult-to-treat DFUs.

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.

In a retrospective case series of 32 patients with Achilles tendinopathy, 66% experienced complete symptom resolution within 45 days after receiving micronized dehydrated human amnion/chorion membrane (mdHACM) injections, indicating its efficacy in pain reduction.

At the first follow-up visit, 84% of patients reported improvement in pain levels, and by the second follow-up, no patients reported severe pain, demonstrating the potential of mdHACM to significantly alleviate pain associated with Achilles tendinopathy.

The human acellular amniotic membrane (HAAM) was found to be effective in treating venous lower limb ulcers, with complete healing in 2 out of 4 patients and significant reductions in ulcer size and depth in all cases.

HAAM treatment not only led to improved healing outcomes, such as >50% granulation tissue formation and the disappearance of infection signs, but it also proved to be more cost-effective compared to traditional treatments like skin autografts.

In a study of 10 patients with category II and III pressure ulcers treated with dehydrated human amnion/chorion membrane (dHACM) allografts, 70% showed a reduction in wound size after the first application, indicating effective initial treatment.

By the end of the eight-week treatment period, 90% of the pressure ulcers had reduced in size, with three ulcers healing completely, suggesting that dHACM is a promising option for treating these types of wounds.

A fresh human placental membrane allograft was successfully used to heal a chronic venous ulcer in an 89-year-old woman, demonstrating its potential effectiveness in treating long-standing wounds.

After 60 days of treatment, the ulcer was completely healed, indicating that the amniochorionic membrane can be a viable therapeutic option for chronic vascular ulcers that do not respond to standard treatments.

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.
