Conference Call Scheduled Today at 8:30 a.m. ET

Concert Pharmaceuticals, Inc. (NASDAQ: CNCE) today reported financial results for the first quarter of 2022.

“We are at an exciting point in our progress with CTP-543, our drug candidate for alopecia areata, a serious autoimmune disorder with significant unmet medical need. Our pivotal trials, THRIVE-AA1 and THRIVE-AA2, have collectively enrolled over 1,200 patients in the U.S., Canada and Europe. We’re grateful to the many individuals who chose to participate in our studies to advance research for this important autoimmune disorder and, in the event of positive data, provide us with the information we need to support filing our New Drug Application with the FDA, which is planned for the first half of next year,” stated Roger Tung, Ph.D., President and Chief Executive Officer of Concert Pharmaceuticals. “We continue to expect to report topline results from the THRIVE‑AA1 trial this quarter. The THRIVE-AA2 topline results are expected to follow soon thereafter, in the third quarter of 2022.”

Recent Business Highlights and Upcoming Milestones

CTP-543: An Investigational Treatment in Phase 3 Trials for Moderate to Severe Alopecia Areata

• Topline Data for THRIVE-AA1 Expected in the Second Quarter of 2022. The Company expects to report topline results from the first CTP-543 Phase 3 trial, THRIVE-AA1, in the second quarter of 2022. THRIVE-AA1 is a randomized, double-blind, placebo-controlled Phase 3 clinical trial of CTP‑543 to evaluate hair regrowth using the Severity of Alopecia Tool (SALT) after 24 weeks of dosing. The trial is evaluating 8 mg and 12 mg twice-daily oral doses of CTP-543 compared to placebo. The trial enrolled 708 adult patients with moderate to severe alopecia areata at sites in the U.S., Canada and Europe.

• Topline Data for THRIVE-AA2 Expected in the Third Quarter of 2022. The Company expects to report topline results from the THRIVE-AA2 trial in the third quarter of 2022. THRIVE-AA2 is a randomized, double-blind, placebo-controlled Phase 3 clinical trial of CTP‑543 to evaluate hair regrowth using SALT after 24 weeks of dosing. The trial is evaluating 8 mg and 12 mg twice-daily oral doses of CTP-543 compared to placebo. The trial enrolled 517 adult patients with moderate to severe alopecia areata at sites in the U.S., Canada and Europe.

• New Drug Application (NDA) Filing for Alopecia Areata Expected in the First Half of 2023. If the CTP-543 clinical program is successful, the Company intends to file an NDA with the U.S. Food and Drug Administration (FDA) in the first half of 2023. If approved, the Company expects that CTP-543 would be one of the first FDA-approved treatments for alopecia areata. The FDA has granted CTP-543 Breakthrough Therapy designation for the treatment of adult patients with moderate to severe alopecia areata and Fast Track designation for the treatment of alopecia areata. Alopecia areata is an autoimmune disease that may affect up to approximately 1.5 million Americans at any given time.¹
