since our inception. In addition, in April 2021, we entered into a Research Subaward Agreement with The Regents of the University of California, on behalf of its San Francisco campus (“UCSF”), whereby up to $5.0 million in costs are reimbursable for clinical activities performed to determine the effectiveness of zotatifin in the treatment of COVID-19. For the three and six months ended June 30, 2020, our net income was $8.6 million and $27.7 million, respectively, and for the three and six months ended June 30, 2021, we had a net loss of $5.5 million and $12.1 million, respectively. As of December 31, 2020 and June 30, 2021, we had an accumulated deficit of $136.7 million and $149.0 million, respectively. Substantially all of our operating losses resulted from expenses incurred in connection with the research and development of our product candidates and development programs, and general and administrative costs associated with our operations.
We expect to continue to incur significant expenses and losses for at least the next several years. We anticipate our expenses will increase substantially as we continue our development of, seek regulatory approval for and potentially commercialize any approved product candidates, hire additional personnel, protect our intellectual property and incur additional costs associated with being a public company. Our net losses may fluctuate significantly from quarter-to-quarter and year-to-year, depending on the timing of our clinical trials and preclinical studies and our expenditures on other research and development activities. As of June 30, 2021, we had $10.9 million in cash and cash equivalents. To fund further operations, we will need to raise additional capital. The net proceeds from the Business Combination will not be sufficient for us to complete the clinical development of any of our product candidates or, if applicable, to prepare for commercializing any product candidate which may receive approval from the FDA or comparable foreign regulatory authority. Accordingly, we expect to finance our cash needs through a combination of equity offerings, debt financings, or other capital sources, including potential additional collaborations, licenses, and other similar arrangements. Adequate funding may not be available to us on acceptable terms, if at all. Our failure to raise capital or enter into such other arrangements when needed would have a negative impact on our financial condition and could force us to delay, limit, reduce, or terminate our research and development programs or other operations, or grant rights to develop and market product candidates that we would otherwise prefer to develop and market ourselves.
The COVID-19 worldwide pandemic continues to evolve, and we will continue to monitor the COVID-19 situation. To date, we have not experienced material disruptions in our business operations. However, while it is not possible at this time to estimate the impact that COVID-19 could have on our business in the future, particularly as we advance our product candidates through clinical development, the continued spread of COVID-19 and the measures taken by governmental authorities, and any future epidemic disease outbreaks, could: disrupt the supply chain and the manufacture or shipment of drug substances and finished drug products for our product candidates for use in our clinical trials and preclinical studies; delay, limit or prevent our employees and CROs from continuing research and development activities; impede our clinical trial initiation and recruitment and the ability of patients to continue in clinical trials, including the risk that participants enrolled in our clinical trials will contract COVID-19 or other epidemic disease while the clinical trial is ongoing, which could impact the results of the clinical trial, including by increasing the number of observed adverse events; impede testing, monitoring, data collection and analysis and other related activities; any of which could delay our clinical trials and preclinical studies and increase our development costs, and have a material adverse effect on our business, financial condition and results of operations.
