LEXINGTON, Mass.–(BUSINESS WIRE)–Concert Pharmaceuticals, Inc. (NASDAQ: CNCE) today announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for CTP-543, a novel, oral Janus kinase (JAK) inhibitor for the treatment of moderate-to-severe alopecia areata, an autoimmune disorder in which the immune system attacks hair follicles, resulting in patchy or complete hair loss.
Fast Track designation is a process designed to facilitate the development and expedite the review of new therapies to treat serious conditions and address unmet medical needs. With Fast Track designation, early and frequent communications between the FDA and the sponsor are encouraged throughout the drug development and review process to help to ensure that questions are resolved quickly.
“Fast Track designation recognizes that alopecia areata is a serious disease in need of effective treatments. We look forward to collaborating with the FDA on the development of CTP-543,” said James Cassella, Ph.D., Chief Development Officer of Concert Pharmaceuticals. “There are no FDA-approved treatments for alopecia areata and CTP-543 would represent a significant medical advance as a potential first-in-class treatment for moderate-to-severe disease.”
Concert is conducting a multi-center, double-blind, randomized, placebo-controlled Phase 2a trial to evaluate the safety and efficacy of CTP-543 in adults with moderate-to-severe alopecia areata. For additional information on the ongoing CTP-543 Phase 2a trial, visit www.clinicaltrials.gov.
About CTP-543 and Alopecia Areata
CTP-543 was discovered by applying Concert’s deuterium chemistry technology to modify ruxolitinib, a drug which selectively inhibits Janus kinases 1 and 2 (JAK1 and JAK2) and is commercially available under the name Jakafi® in the United States for the treatment of certain blood disorders. Ruxolitinib has been used to treat alopecia areata in academic settings, including an investigator-sponsored clinical trial, and has been reported to promote hair growth in individuals with moderate-to-severe disease.
Alopecia areata is an autoimmune disease that results in partial or complete loss of hair on the scalp and body that may affect up to 650,000 Americans at any given time1. The scalp is the most commonly affected area, but any hair-bearing site can be affected alone or together with the scalp. Onset of the disease can occur throughout life and affects both women and men. Alopecia areata can be associated with serious psychological consequences, including anxiety and depression. There are currently no drugs approved by the U.S. Food and Drug Administration (FDA) for the treatment of alopecia areata. Deuterium modification of ruxolitinib was found to alter its human pharmacokinetics in ways which may enhance its use as a treatment for alopecia areata.
The FDA selected alopecia areata as one of eight new disease areas that it focused on under its Patient-Focused Drug Development Initiative (PFDDI) meetings in 2016-2017. The goal of the PFDDI is to bring patient perspectives into an earlier stage of product development. The meeting to discuss alopecia areata was held on Monday, September 11, 2017.

Concert Pharmaceuticals is a clinical stage biopharmaceutical company focused on applying its DCE Platform® (deuterated chemical entity platform) to create novel medicines designed to address unmet patient needs. The Company’s approach starts with approved drugs in which deuterium substitution has the potential to enhance clinical safety, tolerability or efficacy. Concert has a broad pipeline of innovative medicines targeting autoimmune and inflammatory diseases and central nervous systems (CNS) disorders.
