Denver, CO, May 14, 2019 (GLOBE NEWSWIRE) -- Researchers and doctors at the Linda Crnic Institute for Down Syndrome (Crnic Institute), the University of Colorado Department of Dermatology, and the Palo Alto Medical Foundation in California have just published the first report of safe and efficacious use of an immune modulatory strategy to treat alopecia areata in individuals with Down syndrome. The drug featured in the publication is called Xeljanz, also known as Tofacitinib, which belongs to a class of drugs known as ‘JAK inhibitors.’
The results in this publication hold promise not only for the treatment of alopecia areata but could possibly hold the key for other autoimmune disorders and ailments found in people with Down syndrome. This research builds upon the Crnic Institute’s groundbreaking discovery that people with Down syndrome have profound immune system dysregulation and autoimmunity associated with chronic activation of a branch of the immune system known as the interferon response.
Alopecia areata is an autoimmune disorder in which the immune system mistakenly attacks the hair follicles, causing hair loss. People with Down syndrome have up to a ten-fold higher risk of developing alopecia areata than the typical population, as well as increased risk of developing many other immune disorders.
The research team studied how the drug Xeljanz impacted two individuals with Down syndrome who have alopecia areata. The scientists discovered a remarkable recovery of hair growth within weeks of beginning treatment, and with no measurable side effects. The study results were published on April 5, 2019 in the Journal of the American Association of Dermatology Case Reports.
“For the past four years, we have been hypothesizing that partially inhibiting the interferon response with specific drugs would have therapeutic benefits for people with Down syndrome, and these two cases clearly support our hypothesis,” said Dr. Espinosa, Executive Director of the Crnic Institute, an affiliate of the Global Down Syndrome Foundation (Global).
Dr. Espinosa and several expert scientists at the Crnic Institute believe that Xeljanz is a drug that could have a wide range of positive effects on a variety of health issues and the overall well-being of people with Down syndrome. Xeljanz is manufactured by Pfizer, Inc. and approved in the United States for use in other immune disorders including rheumatoid arthritis, psoriatic arthritis, and ulcerative colitis. Xeljanz has not yet been approved to treat alopecia areata.
“Clearly, Global and the Crnic Institute are interested in science that will benefit people with Down syndrome today, or at least as soon as possible,” said Michelle Sie Whitten, President and CEO of the Global Down Syndrome Foundation. “The work on interferon and the potential benefit is astounding. However, there is still much research to be done before people start prescribing JAK inhibitors. We need organized clinical trials starting specifically for people with Down syndrome and now our job is to raise that initial investment of $3 million.”
Numerous JAK inhibitors are currently being tested in clinical trials for alopecia areata and other immune diseases in typical people. Despite the fact that people with Down syndrome have a higher risk of developing alopecia areata, exclusion criteria of these clinical trials typically make it near impossible for a person with Down syndrome to participate.
“The next step is to design and launch a proper clinical trial for JAK inhibitors specifically for people with Down syndrome. This will take a significant amount of resources and effort, as well as strong participation from self-advocates and their families, but it is clearly the right thing to do at this time. The fact that people with Down syndrome have been excluded from previous clinical trials is unacceptable,” Dr. Espinosa said.
Much of the science supported by Global and the Crnic Institute focuses on why people with Down syndrome have a radically different disease spectrum and therefore are highly predisposed to diseases such as Alzheimer’s disease and autoimmune disorders but are also highly protected from diseases such as solid tumor cancers.
