and development expenses, exclusive of any in-process research and development relating to our acquisitions, will increase for the foreseeable future as we continue the development of our drug candidates.
Net Loss
Our net losses were approximately $5.6 million and $8.0 million for the six months ended June 30, 2023 and 2022, respectively, a decrease of approximately $2.4 million or 29.7%. We anticipate our net losses will continue as we advance our research and drug development activities and incur additional general and administrative expenses to meet the needs of our business.
Liquidity and Capital Resources
We have incurred losses since our inception, and, as of June 30, 2023, we had an accumulated deficit of approximately $58.1 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, 2023, we have funded our operations principally with approximately $31.4 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 AIOs.
During the six months ended June 30, 2023, we used approximately $1.7 million of cash in operations, which was attributable to our net loss of approximately $5.6 million, offset by the changes in operating assets and liabilities of approximately $3.7 million and approximately $0.1 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.
Our cash resources are extremely limited. We had cash of approximately $0.4 million as of June 30, 2023. As of August 11, 2023, Scopus and Duet raised aggregate gross proceeds of approximately $2.4 million on a consolidated basis in concurrent financings. Notwithstanding such financings, we continue to have an immediate need for additional financing. Our ability to raise capital continues to be impeded by limited availability of authorized common stock and the current price of our common stock. Further, we are subject to certain stock market requirements relating to, among other things, the amount and nature of the capital that we can raise. There can be no assurance that financing will be available to us on a timely basis and on satisfactory terms, or at all. Failure to obtain sufficient financing on satisfactory terms in the immediate future will have a material adverse effect on us, including possibly being required to substantially curtail or cease our operations.
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.
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 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 any 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, we expect to incur significant commercialization expenses for product sales, marketing, manufacturing and distribution. We anticipate that we will need substantial additional funding in connection with our continuing operations.
