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

Concert Pharmaceuticals, Inc. (NASDAQ: CNCE) today reported financial results for the first quarter of 2021.

“We are committed to advancing CTP-543, our breakthrough therapy candidate for moderate to severe alopecia areata. Patients currently lack effective, approved treatment options. We believe we have the potential to provide patients with a new, clinically meaningful and best-in-class treatment option,” stated Roger Tung, Ph.D., President and Chief Executive Officer of Concert Pharmaceuticals. “We remain on track with our THRIVE-AA Phase 3 clinical program with CTP-543, in support of our New Drug Application that we anticipate filing in early 2023.”

Recent Business Highlights and Upcoming Milestones

CTP-543: An Investigational Treatment for Moderate to Severe Alopecia Areata

• THRIVE-AA1 Phase 3 Trial in Alopecia Areata On Track to Report Topline Data in 2022. The THRIVE-AA1 Phase 3 trial is a randomized, double-blind, placebo-controlled clinical trial of CTP-543 to evaluate hair regrowth after 24 weeks of dosing in approximately 700 adults with moderate to severe alopecia areata. The trial is evaluating 8 mg and 12 mg twice-daily doses of CTP-543 compared to placebo at sites in the U.S., Canada and Europe. The Company expects to report topline results from the THRIVE-AA1 trial in 2022. Additional information about the THRIVE-AA1 trial (NCT04518995) is available at clinicaltrials.gov.

• Initiation of THRIVE-AA2 Phase 3 Trial in Alopecia Areata Expected in May 2021. The Company expects to initiate a second pivotal Phase 3 trial of CTP-543, THRIVE-AA2, later this month. The planned THRIVE-AA2 Phase 3 trial is a randomized, double-blind, placebo-controlled clinical trial of CTP-543 to evaluate hair regrowth after 24 weeks of dosing in approximately 440 adults with moderate to severe alopecia areata. The trial will evaluate 8 mg and 12 mg twice-daily doses of CTP-543 compared to placebo at sites in the U.S., Canada and Europe. Additional information about the THRIVE-AA2 trial (NCT04797650) is available at clinicaltrials.gov.

The presentation will provide an update on the extension study, building on the data presented at the late-breaking news session at the European Academy of Dermatology and Venereology (EADV) in October 2020, during which the Company showed the maintenance of hair regrowth in patients on treatment for at least one year.
