Recent Business Highlights and Upcoming Milestones

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

• Topline Data in 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 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.
  
  
  
  
• Enrollment Completed in the THRIVE-AA2 Phase 3 Trial. Similar to THRIVE-AA1, 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 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. The Company expects to report topline results from the THRIVE-AA2 trial in the third quarter of 2022.
  
  
  
  
• New Drug Application (NDA) Filing Expected for Alopecia Areata 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. 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 time¹.

Partnered Program: AVP-786 for Neurological Disorders

• AVP-786 Late-Stage Trials to Complete in Third Quarter of 2022. Avanir Pharmaceuticals and Otsuka Pharmaceuticals are conducting a number of clinical trials evaluating AVP-786 in certain neurological disorders, including multiple Phase 3 studies in Alzheimer's agitation. Avanir and Otsuka have full responsibility for the development, reporting of clinical results and commercialization of AVP-786. Concert is entitled to potential future milestones and royalties. Two trials are expected to complete in the third quarter of 2022:
  
  
  
  
  • AVP-786 Phase 3 trial in Alzheimer's Agitation is projected to complete in July 2022.
  • AVP-786 Phase 2/3 trial in Negative Symptoms of Schizophrenia is projected to complete in August 2022.

Full Year 2021 Financial Results

• Cash and Investment Position. Cash, cash equivalents and investments as of December 31, 2021 totaled $141.6 million, compared to $130.0 million as of December 31, 2020. In November 2021, the Company raised gross proceeds of $65.0 million under a financing arrangement with BVF Partners L.P. and RA Capital Management, L.P. The financing consisted of the sale of common and preferred stock, warrants and a portion of Concert's right to receive potential future AVP-786 royalties under an existing licensing agreement with Avanir. Under its current operating plan, the Company expects its current cash and cash equivalents to fund the Company into the fourth quarter of 2022. In addition, Concert has the potential to receive an additional $103.1 million upon the full exercise of the warrants issued in connection with the November 2021 financing.
  
  
  
  
• Revenue. Revenue was $32.6 million for the year ended December 31, 2021, compared to $7.9 million for the year ended December 31, 2020.

Revenue recognized in 2020 was the result of the expiration of licensing options under a previous collaboration with Celgene Corporation.
