We operated at a loss since inception in 2003 and have no significant recurring revenue from operations. We anticipate that losses will continue for the foreseeable future. As of June 30, 2025, our accumulated deficit was approximately $922.6 million. Our working capital as of June 30, 2025 was $2.6 million, consisting of $3.7 million in current assets and $1.1 million in current liabilities. Our actual cash requirements may vary materially from those planned because of a number of factors, including changes in the focus, direction and pace of our development programs.
As of June 30, 2025, we had approximately $2.9 million of cash and cash equivalents. In light of our 2023 announced strategic reprioritization and the ensuing streamlining and cost efficiency efforts, we anticipate our cash resources will be sufficient to fund our operations into the first quarter of 2026. In order to continue our operations beyond our forecasted runway, including, if necessary, to continue to explore strategic alternatives, we will need to raise additional capital. Aside from the equity line of credit, we have no committed sources of additional capital at this time. The forecast of cash resources is forward-looking information that involves risks and uncertainties, and the actual amount of our expenses could vary materially and adversely as a result of a number of factors. We have based our estimates on assumptions that may prove to be wrong, and our expenses could prove to be significantly higher than we currently anticipate. Management does not know whether additional financing will be on terms favorable or acceptable to us when needed, if at all. If adequate additional funds are not available when required, we may be unable to persist as a going concern for sufficient time to identify or execute on any strategic alternatives.
Based on the current cash forecast, management has determined that our present capital resources will not be sufficient to fund our planned operations for at least one year from the issuance date of the condensed financial statements, which raises substantial doubt as to our ability to continue as a going concern. This forecast of cash resources and planned operations is forward-looking information that involves risks and uncertainties, and the actual amount of expenses could vary materially and adversely as a result of a number of factors.
