On an ongoing basis, we evaluate our estimates and judgments, including those related to derivative liabilities, accrued expenses and stock-based compensation. We based our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the reported amounts of revenues and expenses that are not readily apparent from other sources. Actual results could differ from those estimates, particularly given the significant social and economic disruptions and uncertainties associated with the ongoing coronavirus pandemic (“COVID-19”) and the COVID-19 control responses.
Our critical accounting policies and significant estimates are detailed in our Annual Report on Form 10-K for the year ended December 31, 2021. Our critical accounting policies and significant estimates have not changed substantially from those previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2021.
Results of Operations
Operating costs:
Operating costs and expenses consist primarily of research and development expenses, including clinical trial expenses, which increase when we are actively participating in clinical trials or we are undertaking substantial one-time expenses following trials, such as for statistical work under the Statistical Analysis Plan, and other activities related to completion and assessment of the trial and its results, and to development of an application for commercial approval of DCVax-L. The operating costs also include administrative expenses associated with trials, in addition to R&D expenses, and increase as such operating activities grow.
In addition to clinical trial related costs, our operating costs may include ongoing work relating to our DCVax products, including R&D, product characterization, and related matters. Going forward, we are also incurring large amounts of costs to carry out and complete statistical analyses, validation work, data reports and other work associated with analyzing the trial results and proceeding.
Following our acquisition of Flaskworks, our operating costs now include the costs for its ongoing operations and its intellectual property filings.
Our operating costs also include, where applicable, the costs of preparations for the launch of new or expanded clinical trial programs. The preparation costs include payments to regulatory consultants, lawyers, statisticians, sites and others, evaluation of potential investigators, the clinical trial sites and the CROs managing the trials and other service providers, and expenses related to institutional approvals, clinical trial agreements (business contracts with sites), training of medical and other site personnel, trial supplies and other. Additional substantial costs relate to the maintenance and substantial expansion of manufacturing capacity, in both the U.S. and Europe.
Our operating costs also include legal and accounting costs in operating the Company.
Research and development:
Discovery and preclinical research and development expenses include costs for substantial external scientific personnel, technical and regulatory advisers, and others, costs of laboratory supplies used in our internal research and development projects, travel, regulatory compliance, and expenditures for preclinical and clinical trial operation and management when we are actively engaged in clinical trials.
Because we are a pre-revenue company, we do not allocate research and development costs on a project basis. We adopted this policy, in part, due to the unreasonable cost burden associated with accounting at such a level of detail and our limited number of financial and personnel resources.
General and administrative:
General and administrative expenses include personnel related salary and benefit expenses, cost of facilities, insurance, travel, legal services, property and equipment and amortization of stock options and warrants.
