STAINES-UPON-THAMES, United Kingdom, Feb. 14, 2018 /PRNewswire/ -- Mallinckrodt plc (NYSE: MNK), a leading global specialty pharmaceutical company, today confirmed enrollment of the first patient in the company's Phase 1 study assessing the safety and tolerability of ExpressGraft™C9T1 skin tissue in the treatment of subjects with diabetic foot ulcers (DFUs). ExpressGraft-C9T1 skin tissue has been genetically modified to express elevated levels of the human cathelicidin host defense peptide.
"I am excited that the first patient has been enrolled in this important Phase 1 study. Diabetic foot ulcers and resulting complications can be physically debilitating and lead to emotionally devastating problems in this population," said Thomas E. Serena, MD, FACS, FACHM, MAPWCA, CEO and Medical Director SerenaGroup and lead investigator for the ExpressGraft-C9T1 skin tissue study. "This research may help expand options and further our understanding of diabetic complications related to DFUs."
"Mallinckrodt is committed to providing treatment options for patients with unmet medical needs. Enhancement of antimicrobial action through genetic modification may benefit patients with chronic, difficult-to-heal wounds such as those seen in patients with diabetes," said Lynn Allen-Hoffmann, Senior Vice President of Regenerative Medicine at Mallinckrodt. "We are pleased to enroll the first patient in our Phase 1 ExpressGraft study."
About the Study
The Phase 1 study is titled "ExpressGraft-C9T1 Skin Tissue as a Treatment of Diabetic Foot Ulcers." The study is designed as a prospective, open-label trial focused on assessing the safety and tolerability of ExpressGraft-C9T1 skin tissue in the treatment of DFU. Targeted enrollment for this study is up to six subjects with a confirmed diagnosis of diabetes and who have foot ulcers. Subjects will each receive a single application of ExpressGraft-C9T1 skin tissue on a single identified study DFU following a 10-14 day run-in period. Any subjects requiring additional treatment will receive protocol-defined dressings as necessary. Enrollment is staged with a minimum of one week between each subject.
The safety and tolerability of ExpressGraft-C9T1 skin tissue will be evaluated by monitoring adverse events, clinically significant vital signs, blood chemistry, safety laboratory values including but not limited to immunological testing, and incidence of treatment site infection through the 12-month study session.

About Diabetic Foot Ulcers
More than 22 million people were diagnosed with diabetes in the U.S. in 2012 (7.7% of the population).1 DFUs are open sores or wounds that occur on the foot in up to 25 percent of patients with diabetes during their lifetime1,2 and are the cause of more hospitalizations than any other complication of diabetes.3 Diabetes is the leading cause of non-traumatic lower extremity amputations in the U.S. In patients with diabetes, complications of DFUs are considered the main cause of lower extremity amputations.2,4 Foot ulceration precedes 85 percent of diabetes-related amputations.5 According to the American Podiatric Medical Association, 6 percent of patients with DFUs will be hospitalized for a complication related to the foot ulcer and approximately 14-24 percent of those will ultimately require amputation.6
About ExpressGraft-C9T1 Anti-Infective Tissue
ExpressGraft-C9T1 skin tissue builds on many of the same technologies pioneered in the development of StrataGraft, a skin substitute which is currently in Phase 3 for the treatment of severe burns. ExpressGraft-C9T1 is the first genetically engineered human skin substitute in development that expresses elevated levels of the human cathelicidin host defense peptide. Cathelicidin is a multifunctional human defense protein with broad-spectrum antimicrobial activity and is a mediator of wound healing through promotion of angiogenesis and epithelialization. ExpressGraft-C9T1 skin tissue and StrataGraft are both investigational products and are not approved by regulatory authorities. Safety and efficacy have not been established.
