- 35% of subjects in the intent-to-treat AMNIOEXCEL ® plus SOC cohort achieved complete wound closure at or before week six, compared with 0% of subjects in the intent-to-treat SOC alone cohort - these results are statistically significant (p=0.017)
- 45.5% of subjects in the per-protocol AMNIOEXCEL ® plus SOC cohort achieved complete wound closure at or before week six, compared with 0% of subjects in the per-protocol SOC alone cohort - these results are statistically significant (p=0.0083)
- No treatment-related adverse events were reported in either cohort
This Level 1 published evidence supports the use of AMNIOEXCEL ® for the treatment of non-closing diabetic foot ulcers.Stephen T. Wills, Derma Sciences Executive Chairman and Interim Chief Executive Officer, said, "Most importantly, these results are great news for people suffering from chronic, hard-to-treat diabetic foot ulcers. In this well-designed and tightly administered study, patients treated with AMNIOEXCEL ® along with standard of care had a far superior wound closure and a more rapid rate of wound closure than those treated with standard of care alone. These results are statistically significant and clinically meaningful, which is very important to health plan decision-makers in reviewing new coverage decisions. This study will enhance our efforts to gain positive coverage decisions from the remaining three Medicare Administrative Contractors who currently do not have a policy on AMNIOEXCEL ® and require robust, evidence-based studies for their local coverage determinations." Barry J. Wolfenson, Group President of Advanced Wound Care, commented, "Given the large proportion of people with type 1 or type 2 diabetes who will ultimately develop a foot ulcer, and the high rate of amputation associated with diabetic foot ulcers along with the mortality associated with these amputations, we are thrilled to share these exceptional data with the doctors and nurses who care for these patients on a daily basis. This should give clinicians high confidence in AMNIOEXCEL ® as a clinically safe and efficacious product, offering them a viable, cost-effective solution." About the Trial Design and Findings All subjects enrolled in this study received SOC throughout the trial, including the two-week run-in period. SOC included debridement of necrotic/non-viable tissue, moist wound dressings, off-loading and infection surveillance and management. Patients with chronic, diabetes-related wounds between 1 cm 2 and 25 cm 2 in area, which failed to close more than 30% in area during the two-week SOC run-in period, were randomly assigned 1:1 to receive AMNIOEXCEL ® + SOC or SOC alone. Subjects in both groups returned to the clinic every week for dressing changes, wound inspection, debridement and dressing application. In these weekly assessments, the wounds also were photographed and measured. The primary endpoint of the study, complete closure of the ulcer without drainage or need for dressings, was assessed each week. Of the 49 patients screened for participation, 29 were randomized with 15 allocated to the AMNIOEXCEL ® + SOC group and 14 allocated to the SOC alone group. All randomized subjects were included in the intent to treat (ITT) analysis and the 21 subjects (11 AMNIOEXCEL ® + SOC and 10 SOC) who completed the six-week trial were included in the per-protocol (PP) analysis. Subjects in the AMNIOEXCEL ® + SOC group demonstrated a significantly greater closure rate than the SOC alone subjects, with 35% closure at six weeks in the AMNIOEXCEL ® +SOC group vs. 0.0% closure in the SOC group in the ITT population (p=0.017), and 45.5% closure at six weeks in the AMNIOEXCEL ® +SOC group vs. 0.0% closure in the SOC group in the PP population (p=0.0083). The study was implemented at eight U.S. clinical sites.
