Liquidity, Uncertainties and Going Concern	2. Liquidity, Uncertainties and Going Concern The Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year after the date that the consolidated financial statements are issued. Since its inception, the Company has funded its operations primarily with proceeds from the sale of its equity securities and borrowings under the 2018 Credit Facility. The Company has incurred recurring losses since its inception and had an accumulated deficit of $233.6 million on December 31, 2021. The Company expects to continue to generate operating losses for the foreseeable future. The Company expects that its cash and cash equivalents will be sufficient to fund its operating expenses and capital expenditure requirements into the second half of 2024. The future viability of the Company beyond that point is dependent on its ability to raise additional capital to finance its operations. The Company is subject to risks common to early stage companies in the biotechnology industry including, but not limited to: having a limited operating history and no products approved for commercial sale; having a history of significant losses; its need to obtain additional financing; dependence on its ability to advance its current and future product candidates through clinical trials, marketing approval and commercialization; the lengthy and expensive nature and uncertain outcomes of the clinical development process; the lengthy, time consuming and unpredictable nature of the regulatory approval process; the results of preclinical studies and early stage clinical trials that may not be predictive of future results; dependence on its key personnel; risks related to patent protection and the Company’s pending patent applications; dependence on third party collaborators for the discovery, development and commercialization of current and future product candidates; and significant competition from other biotechnology and pharmaceutical companies. Even if the Company’s development efforts are successful, it is uncertain when, if ever, the Company will realize significant revenue from product sales. Due to the evolving and uncertain global impacts of the ongoing COVID-19 pandemic, we cannot precisely determine or quantify the impact this pandemic will have on our business operations in the future. We have been carefully monitoring the COVID-19 pandemic and its potential impact on our business and have taken important steps to help ensure the safety of our employees and their families and to reduce the spread of COVID-19 community-wide. We are continuing to assess the potential impact of the COVID-19 pandemic on our current and future business and operations, including our expenses and clinical trials, as well as on our industry and the healthcare system. To date, we have been able to continue to pursue our Phase 1 clinical trial with only minor delays despite the COVID-19 pandemic.
