The U.S. Food and Drug Administration has approved a new biologic drug that is based on seminal research by Emma Guttman-Yassky, MD, Professor of Dermatology, and Medicine (Clinical Immunology), at the Icahn School of Medicine at Mount Sinai. The drug, dupilumab, was approved in March—fast-tracked because it is a “breakthrough therapy” for adult patients with uncontrolled eczema. “It brings hope to patients who have tried everything.” Dr. Guttman-Yassky says.
One of them is her patient Austin Jacobson, a personal injury defense lawyer in Manhattan. “Living with eczema is like having poison ivy from head to toe,” he says. “You can’t sleep because you’re itching so badly. It affects every single aspect of your life.” Mr. Jacobson took part in clinical trials of the drug, which is injected every two weeks, and still uses it now. He says he felt relief from itching “two hours after taking the first injection.”
At least 31 million Americans are affected by some form of eczema. The most common type is atopic dermatitis, caused by a combination of genetic, immune and environmental factors. Dupilumab, sold by Regeneron Pharmaceuticals as Dupixent, is an antibody that binds to a protein, IL-4 receptor alfa, inhibiting the inflammatory response that leads to eczema’s rashes and itching. Dr. Guttman-Yassky’s laboratory was the first to map immune pathways underlying eczema, including those now targeted by dupilumab and other drugs in clinical trials.
Her team is among those testing more new therapies, including a drug made by Pfizer Inc. that targets a different immune molecule, interleukin 22 or IL-22. Dr. Guttman’s research was the first to identify the lymphocytes that produce IL-22, and show their link to eczema. With funding from the National Institutes of Health, she designed a study that tested IL-22 antibody targeting in the clinic and in the lab—a treatment that is showing promising preliminary results.
“These are exciting times for patients with eczema, and for me specifically, as I am able to contribute to the scientific development for this disease and help millions of patients worldwide,” Dr. Guttman-Yassky says. “This is a dream come through for a physician-scientist.”
As for Mr. Jacobson, he says that his skin, which had been “100 percent” covered with a scaly, flaking rash, is now largely clear. “The drug works,” he says of dupilumab. “It gives you your life back.”
Dr. Guttman-Yassky has received research funding from Regeneron, and drug and research support from Pfizer, and is working with most companies developing treatments for atopic dermatitis/eczema.
