Exicure Provides Business Update Amid COVID-19 Pandemic

CHICAGO & CAMBRIDGE, Mass.–([1])–Exicure, Inc. (NASDAQ:XCUR), the pioneer in gene regulatory and immunotherapeutic drugs utilizing spherical nucleic acid (SNA™) technology, today provided an update on the Company’s operations in response to the global COVID-19 pandemic and the Company’s current evaluation of the impact the pandemic may have on the Company’s clinical trials, preclinical research and development (R&D) and general business operations.

Exicure is carefully monitoring the developing COVID-19 crisis and we have taken active measures, both as required by government regulation and as judgement suggests, to protect the health of our employees, their families, our communities, as well as clinical trial investigators, patients, and caregivers,” said Dr. David Giljohann, Exicure’s Chief Executive Officer. “While health and safety are our first priorities, we also have a strong commitment to our fundamental mission of serving patients with unmet medical needs. We are taking appropriate actions to continue our critical research and development programs and are grateful to our employees and their families for their commitment to this mission.”

Employees and Business Operations

On March 21, 2020, Governor Pritzker of Illinois announced a “stay-at-home” order restricting all Illinois residents to their homes, with few limited exceptions, until at least April 7, 2020. However, the Governor also designated certain businesses, such as biotechnology companies, as “essential” businesses, thereby permitting Exicure to continue its R&D operations. The Company continues to pursue its pre-clinical development programs and clinical programs as further described below.

AST-008, for Immuno-oncology

Exicure continues to monitor its ongoing trial of AST-008. As previously disclosed, the Company is completing the Phase 1b stage of its Phase 1b/2 clinical trial of AST-008 in both Merkel cell carcinoma and in cutaneous squamous cell carcinoma and is preparing to begin the Phase 2 stage of dose expansion for intratumoral AST-008 in patients with advanced or metastatic Merkel cell carcinoma or cutaneous squamous cell carcinoma. At this time, and given the severity of both of these indications, Exicure continues to believe that the Phase 2 stage of the trial will begin as expected in the second quarter of 2020. Exicure currently has seven trial sites open. The Company continues to be in close communication with its clinical sites and, among other things, has confirmed that AST-008 is available for conduct of the trial at each of the sites. Exicure remains committed to maintaining its development plans of AST-008 and continues to monitor the rapidly evolving situation.

AST-008, as an immune system adjuvant

In 2015, Exicure scientists published experimental results examining the potential of immuno-stimulatory SNAs such as AST-008 to function as vaccine adjuvants. Those published studies demonstrated that immuno-stimulatory, SNA–based, adjuvants induced a significant and desired immunological memory response to a model peptide in mice, indicating that SNAs may be useful in vaccines. Exicure is considering various tactics for advancing this feature of the SNA platform and the potential for collaboration with government agencies and pharmaceutical companies in the vaccine space.


Exicure’s pre-clinical development program in Friedreich’s ataxia is being conducted in the Company’s R&D labs. Preclinical research is ongoing. The Company affirms its guidance that IND-enabling studies for XCUR-FXN are expected in late 2020.


As previously disclosed, Exicure entered into a collaboration with Allergan Pharmaceuticals International Limited in late 2019 to pursue preclinical research and discovery in two pre-clinical programs related to the treatment of hair loss disorders. R&D activities continue to progress under this collaboration and, as of the date of this press release, there is no current anticipated effect on these activities. In early 2019, Exicure entered into a collaboration agreement with Dermelix Biotherapeutics under which Dermelix will develop a targeted therapy for the treatment of Netherton Syndrome (NS). As of the date of this press release, preclinical R&D activities under this collaboration remain ongoing.

Cash Position

The Company is currently evaluating the impact of COVID-19 on its 2020 financial guidance and expects to provide more detail, to the extent practicable, in connection with its first quarter 2020 earnings update.

Exicure does not anticipate a change to its prior guidance and continues to believes its current cash will finance operations into early 2022. Preliminary unaudited cash, cash equivalents and short-term investments as of February 29, 2020 was approximately $107.7 million.
