CHICAGO & CAMBRIDGE, Mass.–(BUSINESS WIRE)–Exicure, Inc.^® (NASDAQ: XCUR) announced the results of its previously disclosed independent internal investigation and a number of strategic actions aimed to reduce cash spend and prioritize the Company’s therapeutic pipeline.

The Audit Committee of the Board of Directors of the Company (the “Audit Committee”) today announced the findings of the internal investigation initiated and overseen by the Audit Committee and conducted by outside counsel in connection with alleged improprieties that Grant Corbett, Ph.D., the Company’s former Group Lead of Neuroscience, claimed to have committed with respect to the Company’s XCUR-FXN preclinical program.

The results of the investigation are summarized below.

• Beginning in the autumn of 2020, Dr. Corbett misreported raw data from certain research and development experiments related to XCUR-FXN;
• Dr. Corbett misreported the results of at least three different experiments that were conducted through at least February 2021;
• The misreported data related solely to efficacy rather than safety of XCUR-FXN;
• The misreported data was included in various public presentations and SEC filings from as early as January 7, 2021 through as late as August 12, 2021;
• Dr. Corbett acted alone in misreporting the data, without the assistance or knowledge of anyone else at the Company, including Company management and other research and development employees and did not inform anyone at the Company of his actions until his resignation in November 2021;
• Company management reasonably relied on Dr. Corbett’s analysis when making public statements that included Dr. Corbett’s misreported data; and
• No other Company program was impacted by Dr. Corbett’s misreporting of the XCUR-FXN data.

After a review of the Audit Committee’s findings from the investigation and in combination with a previously initiated strategic review of the Company’s business plans and objectives and its existing cash resources, the Company’s Board of Directors has implemented the following approved plan:

• A staggered workforce reduction of approximately 50%, expected to be completed by January 2022;
• Discontinuation of further enrollment and the ethical wind down of the Company’s ongoing Phase 1b/2 cavrotolimod (AST-008) clinical trial in patients with solid tumors
• Indefinite suspension of further development of the Company’s XCUR-FXN program for the treatment of Friedreich’s ataxia
• Restructuring and realignment of the Company’s executive team as follows, effective today:
  • Brian C. Bock, the Company’s former Chief Financial Officer, has been appointed as the Company’s President and Chief Executive Officer, replacing David Giljohann, and was appointed as a member of the Board.
  • Dr. David Giljohann, the Company’s former Chief Executive Officer, has resigned from the Board and will serve as Chief Technology Officer through January 31, 2022.
  • Matthias Schroff, the Company’s former Chief Operating Officer, has assumed the new role of Chief Scientific Officer;
  • Sarah Longoria, the Company’s former Vice President of Human Resources has been appointed as the Company’s Chief Human Resources Officer and Chief Compliance Officer; and
  • Douglas Feltner, M.D., the Company’s Chief Medical Officer, has agreed to assist in the wind down of the cavrotolimod and XCUR-FXN programs and will depart the Company on January 31, 2022.

Exicure expects to realize approximately $6.0 million in employee related cost savings in 2022, plus additional costs relating to the elimination of the cavrotolimod and XCUR-FXN programs. The Company estimates that it will incur total expenses relating to the restructuring of approximately $1.2 million, consisting of severance and termination-related costs and expects to record a significant portion of these charges in the fourth quarter of 2021.

The Company intends to align its research and development resources to support (i) the development of its preclinical program targeting SCN9A for neuropathic pain, (ii) the continued advancement of its partnered programs with Ipsen Biopharm Limited to develop SNA-based treatments in neuroscience targeting Huntington’s disease and Angelman syndrome, (iii) its continued advancement of its partnered program with AbbVie to develop SNA-based treatments for hair loss disorders, as well as (iv) the continued research and development of other undisclosed therapeutic product candidates.

The Company also announced a prepayment of $10.0 million of its outstanding loans under its senior secured term loan debt facility with MidCap Financial Trust, as agent, and Silicon Valley Bank (SVB), leaving a remaining outstanding balance of $7.5 million, which will remain subject to the existing terms under the loan facility.

“This has been a difficult time for all of our stakeholders and Exicure employees. I want to first thank the employees impacted by our workforce reduction for their significant contributions in pursuing treatments for patients with unmet medical needs and wish them success in their future endeavors. Although this unfortunate event will have residual effects, I strongly believe there is great value to be unlocked at Exicure with our proprietary Spherical Nucleic Acid (SNA) technology, and I look forward to advancing our promising programs in pain and other neuroscience diseases and continuing to closely work with our partners to develop innovative therapies for the treatment of genetic disorders,” stated Brian Bock, President and Chief Executive Officer, Exicure.

“On behalf of the Board of Directors, I want to thank David Giljohann for his discoveries and contributions to the development of our proprietary SNA architecture, commitment in building Exicure from the ground up and leadership during his time at the Company,” said Tim Walbert, Chairman of the Board, Exicure. “We look forward to working closely with Brian Bock as he assumes leadership of the Company. The Board believes Brian’s disciplined approach as well as his financial and investment banking background make him well suited to develop the new strategic path for Exicure and navigate the Company through the next phase in the Company’s evolution.”
