MIAMI -- There are an estimated 20 million diabetics in the U.S., and at any given time about 1.5 million of them suffer from non-healing foot ulcers. These wounds can lead to amputation or even death.

But now researchers at the University of Miami are joining in a nationwide trial for a new topical treatment that may save limbs and lives.

"It's called Excellarate, and it utilizes gene therapy to speed healing," explained Dr. Robert Kirsner, professor and vice chairman of the Department of Dermatology at UM.

Kirsner said several factors affect a diabetic's ability to heal, including vascular problems, loss of sensation or neuropathy and lack of growth factors.

"We believe this topical agent helps your cells produce more growth factors that may be missing in a diabetic wound," said Kirsner.
