and drug development activities and incur additional general and administrative expenses to meet the needs of our business, including fees, costs and expenses relating to the Adverse Parties litigation.
Liquidity and Capital Resources
We have incurred losses since our inception and, as of June 30, 2022, we had an accumulated deficit of approximately $49.4 million. We anticipate that we will continue to incur losses for at least the next several years. Since April 18, 2017 (inception) through June 30, 2022, we have funded our operations principally with approximately $29.1 million in gross proceeds from the sale of convertible notes, common stock, warrants and units comprised of common stock and warrants, the exercise of a portion of such warrants, and units comprised of common stock and additional investment options (“AIOs”).
During the six months ended June 30, 2022, we used approximately $6.9 million of cash in operations, which was attributable to our net loss of approximately $8.0 million, the changes in operating assets and liabilities of approximately $0.9 million, and approximately $0.2 million of non-cash expenses.
We are party to litigation in several matters as of the date hereof. Litigation is highly unpredictable and the costs of litigation, including legal fees and expenses, and the possible liabilities, including monetary damages, to which we could become subject could be significant. Any such liabilities could have a material adverse effect on us. Our existing capital resources will not be sufficient to fully implement our business plan, including the development of our drug candidates, while also continuing to be subject to or pursuing ongoing litigation. See “Legal Proceedings”.
On January 13, 2022, we received a deficiency notification letter from the Listing Qualifications Staff of the Nasdaq Stock Market LLC (“Nasdaq”) indicating that the Company was not in compliance with Nasdaq Listing Rule 5500(b)(2) requiring listed securities to maintain a minimum market value of listed securities of $50,000,000. On July 13, 2022, we received an additional letter from Nasdaq stating that because the Company had not regained such compliance as of July 12, 2022, trading of our common stock on Nasdaq would be suspended on July 22, 2022 and removed from listing and registration, unless we were to request an appeal to a Nasdaq hearings panel by July 20, 2022, which we requested prior to such deadline. We have a hearing with Nasdaq scheduled for late August 2022 at which the panel will consider our plan for regaining compliance. Until the hearings panel renders a decision on our appeal, this delisting action will be stayed and our common stock will continue to be listed on Nasdaq. Our plan for regaining compliance requires, among other things, that we raise additional capital.
We will require additional financing and there can be no assurance that any such financing will be available on satisfactory terms, or at all. Our ability to raise capital is currently impeded by limited availability of authorized common stock. Further, failure to obtain additional financing, as necessary, will have a material adverse effect on us.
Our ability to fund our operations is dependent upon management’s plans, which include raising capital through issuances of debt and equity securities, securing research and development grants, and controlling our expenses. A failure to raise sufficient financing and/or control expenses, among other factors, will adversely impact our ability to meet our financial obligations as they become due and payable and to achieve our intended business objectives.
This evaluation is further impacted by the ongoing pandemic relating to the COVID-19 pandemic. While the extent of its impact depends largely on the spread and duration of the outbreak, the pandemic has and may still result in disruptions to capital raises, employees, and vendors which has and may still result in negative impacts to our operational and financial results.
Accordingly, based on the considerations discussed above, management has concluded there is substantial doubt as to the Company’s ability to continue as a going concern within one year after the date the condensed consolidated financial statements are issued.
Future Funding Requirements
We have not generated any revenue. We do not know when, or if, we will generate any revenue from product sales. We do not expect to generate significant revenue from product sales unless and until we obtain regulatory approval of and commercialize any of our drug candidates. At the same time, we expect our expenses to increase in connection with our ongoing development activities, particularly as we continue to research, develop, and seek regulatory approval for, our drug candidates. We expect to incur additional costs associated with operating as a public company. In addition, subject to obtaining regulatory approval of any of our drug candidates,
