"The second quarter was marked by important new expansion," said Dr. David Giljohann Exicure’s Chief Executive Officer. "We grew our organization with the addition of neurology expert, Dr. Douglas Feltner, as Chief Medical Officer, expanded our clinical team and opened additional clinical sites in support of our Phase 2 clinical trial in cancer patients using our drug candidate, cavrotolimod. In July, we moved into our new 30,000 sq. ft. laboratory and corporate headquarters where our R&D team continues to advance our growing neurology therapeutic area," concluded Dr. Giljohann.
XCUR-FXN, Exicure’s Friedreich’s ataxia therapeutic candidate
Despite the ongoing COVID-19 pandemic, our laboratories have continued operations with limited impact on our research and development activities.
We remain on track to initiate IND-enabling studies for Friedreich’s ataxia in the fourth quarter of this year.
Cavrotolimod (AST-008) Phase 1b/2 clinical trial is open and actively enrolling patients
In the second quarter of 2020, we began enrolling patients in the Phase 2 dose expansion phase of the clinical trial of intra-tumoral cavrotolimod in combination with approved checkpoint inhibitors pembrolizumab or cemiplimab, to treat patients with advanced or metastatic Merkel cell carcinoma or cutaneous squamous cell carcinoma.
Currently, 14 clinical trial sites are open, and we expect to open up to 11 additional sites for a potential total of 25 sites.
We are continuing to monitor the impact that COVID-19 may have on the trial’s patient enrollment and safety, site initiation, and study integrity. We have put in place and continue to maintain a variety of measures to mitigate the effects of COVID-19 and our top priority is to maintain patient safety and trial continuity.
Second Quarter Financial Results, Financial Guidance and Recent Developments
Cash Position: Cash, cash equivalents, and short-term investments were $85.8 million as of June 30, 2020 as compared to $98.8 million as of March 31, 2020.
Research and Development (R&D) Expenses: Research and development expenses were $7.0 million for the quarter ended June 30, 2020, as compared to $3.4 million for the quarter ended June 30, 2019. We have increased full-time staffing in R&D from 23 at June 30, 2019 to 41 at June 30, 2020 and the associated increase in activity, in addition to growth in cavrotolimod (AST-008) clinical trial activities, has driven our increase in R&D costs. The increase in staffing and associated increases in platform and discovery related costs reflects increased preclinical R&D activities associated with our collaboration with Allergan plc, increased costs related to XCUR-FXN, our Friedreich’s ataxia program, as well as other preclinical discovery work in neurology and ophthalmology.
General and Administrative (G&A) Expenses: General and administrative expenses were $2.2 million for the quarter ended June 30, 2020 as compared to $2.0 million for the quarter ended June 30, 2019. This increase is primarily due to higher legal costs associated with operating as a public company, higher franchise tax costs, and higher D&O insurance expense, partially offset by lower travel and other costs.
Net Loss: We had a net loss of $4.3 million for the quarter ended June 30, 2020 as compared to a net loss of $5.2 million for the quarter ended June 30, 2019. This decrease in net loss of $0.9 million was driven principally by the recognition of $4.8 million of revenue associated with our collaboration with Allergan plc, offset by the increases in R&D expenses and G&A expenses discussed above.
Capital Resources Guidance: We believe that, based on our current operating plans and estimates of future expenses, as of the date of this press release, our existing cash, cash equivalents and short-term investments will be sufficient to fund our operations into early 2022.
Response to COVID-19: With the global spread of the ongoing COVID-19 pandemic in the first half of 2020, we have been closely monitoring developments and have taken active measures to protect the health of our employees and their families, our communities, as well as our clinical trial investigators, patients and caregivers. We continue to carefully manage laboratory staffing and take other appropriate managerial actions to maintain progress on our preclinical and collaboration programs. We also continue to work closely with our third-party manufacturers and other partners to manage our supply chain activities and will take such action as we believe appropriate with our clinical operations to maintain patient safety and trial continuity.
About our Pipeline
Neurology
In December 2019, Exicure announced the development of XCUR-FXN, an SNA–based therapeutic candidate for the treatment of Friedreich’s ataxia (FA). FA is driven by triplet repeats in the frataxin gene which compromises the patient’s ability to generate adequate levels of frataxin protein. Exicure believes its SNA technology has the potential to address this genetic challenge and that its therapeutic strategy may lead to increases in the frataxin protein. Exicure plans to design and develop XCUR-FXN with guidance from, and in collaboration with, the Friedreich’s Ataxia Research Alliance (FARA). Preclinical research is ongoing and IND-enabling studies for XCUR-FXN are expected to commence in late 2020.
Exicure is continuing preclinical research on the application of its SNA technology in neurological conditions, building on its early proof-of-concept work with nusinersen and its new therapeutic candidate, XCUR-FXN. Exicure is currently exploring additional neurological conditions, including spinocerebellar ataxia, Batten disease, amyotrophic lateral sclerosis (ALS) and Huntington’s disease.
Immuno-oncology; Cavrotolimod (AST-008)
Cavrotolimod (AST-008) is an investigational SNA consisting of toll-like receptor 9 (TLR9) agonists designed for immuno-oncology applications. Exicure has now dosed 20 patients and completed enrollment in the Phase 1b stage of the Phase 1b/2 clinical trial. To date, we have not observed any treatment related serious adverse events or any dose-limiting toxicity.
Biomarker data from the Phase 1b stage of the clinical trial showed dose-related systemic immune activation and a trend towards increased tumor immune cell infiltration.
In the second quarter of 2020, we dosed the first patient in a Phase 2 dose expansion phase of our Phase 1b/2 clinical trial for intra-tumoral cavrotolimod in combination with pembrolizumab or cemiplimab to treat two cohorts of patients with advanced or metastatic Merkel cell carcinoma or cutaneous squamous cell carcinoma. Each cohort is expected to enroll up to 29 patients.
Collaborations
In late 2019, Exicure entered into a collaboration, option and license agreement with Allergan plc, which was acquired by AbbVie Inc. in May 2020, and is now actively engaged in preclinical research and discovery in two programs related to the treatment of hair loss disorders. In early 2019, Exicure also entered into a collaboration agreement with Dermelix Biotherapeutics under which Dermelix has the option to develop a targeted therapy for the treatment of Netherton Syndrome (NS).
