Shire plc Falls After Scrapping Dermagraft as Leg Ulcer Therapy
Published: Aug 25, 2011
The international pivotal trial, which enrolled more than 500 patients in eight countries, was designed as a prospective, multicenter, randomized, controlled clinical study to assess the product’s safety and efficacy in the promotion of healing venous leg ulcers.
When combined with compression therapy Dermagraft achieved a higher closure rate of venous leg ulcers than compression therapy alone. However, the data did not meet the primary end point mutually agreed upon with the FDA and EMA. The primary end point of the trial was complete healing (100% re-epithelialization, with no presence of scab or drainage) of venous leg ulcers by 16 weeks. In addition, there was a need to show a minimum absolute level of superiority over compression therapy.
Dermagraft is a bio-engineered skin substitute, FDA approved and currently marketed for the treatment of diabetic foot ulcers (DFUs). A venous leg ulcer indication would have expanded the utility of Dermagraft in a chronic wound setting.

Dermagraft is indicated for use in the treatment of full-thickness diabetic foot ulcers greater than six weeks duration, which extend through the dermis, but without tendon, muscle, joint capsule, or bone exposure. Dermagraft should be used in conjunction with standard wound care regimens and in patients that have adequate blood supply to the involved foot. Dermagraft is contraindicated for use in ulcers that have signs of clinical infection or in ulcers with sinus tracts. Dermagraft is contraindicated in patients with known hypersensitivity to bovine products, as it may contain trace amounts of bovine.
