Miller School Researchers to Seek Subjects for Dermatology Clinical Trial
The University of Miami Miller School of Medicine’s Department of Dermatology and Cutaneous Surgery will soon begin registering subjects for a clinical study investigating treatments for a rare but often fatal skin disease.
“It’s the deadliest disease in dermatology,” said Paolo Romanelli, M.D., professor of dermatology, referring to what is known generically as toxic epidermal necrolysis or TEN. “Many medical professionals have never seen it because it is so rare, but it is very dangerous for those few patients who develop it.”
Romanelli is one of the founders of a global initiative called IRTEN — the International Registry for Toxic Epidermal Necrolysis — that opened in 2016 to oversee the collection of clinical data and biological specimens. The Miller School is one of four IRTEN founding centers in the world; the others are located at institutions in Zürich, Paris and Kyoto.
TEN has a closely related disease: Steven Johnson Syndrome (SJS). Both are typically a dreaded side effect of medications. They are characterized by skin and mucous membrane tenderness and erythema, as well as extensive detachment of the skin. The term SJS is used for when the detachment affects 10 percent or less of the entire body surface, whereas TEN refers to a detachment of greater than 30 percent of the entire body surface skin. The mortality rate of TEN can be 35 percent or higher.
“Only one or two patients out of 1 million develop the disease each year,” said Fabrizio Galimberti, M.D., Ph.D., a dermatology resident who, working with Dr. Romanelli and another resident, Yumeng Li, M.D., will lead the study. “However, for HIV-positive patients, that frequency jumps to one in 1,000 patients.”
Miami-Dade County is currently the national epicenter — the location with the greatest number — of new HIV infections. Broward County is number two. That, along with the fact that seminal studies in the treatment of the condition have been conducted at the Miller School, and that Dr. Romanelli has a very good academic relationship with Lars French, M.D., Ph.D., chairman of the Department of Dermatology at Zürich University Hospital and the ideator of IRTEN, are some of the reasons the Miller School is one of the four IRTEN research hubs.
“This research is needed because right now there is no consensus among clinicians about how to treat these diseases,” said Galimberti, who gave a detailed overview of current treatment modalities at the Miller School Department of Dermatology’s recent grand rounds. “We have a lot of goals for this study, including analyzing the value of different treatment strategies and looking for predictive biomarkers.”
