COVID-19
In March 2020, the World Health Organization declared the novel coronavirus disease 2019 (“COVID-19”) outbreak a pandemic. In order to mitigate the spread of COVID-19, governments have imposed unprecedented restrictions on business operations, travel, and gatherings, resulting in a global economic downturn and other adverse economic and societal impacts. The COVID-19 pandemic has also overwhelmed or otherwise led to changes in the operations of many healthcare facilities, including clinical trial sites. However, our laboratories have continued operations throughout the pandemic mostly without interruption.
The impact of the COVID-19 pandemic (including the impact of emerging variant strains of the COVID-19 virus) on our business and financial performance is uncertain and depends on various factors, including the scope and duration of the pandemic, the efficacy and global distribution of vaccines, government restrictions and other actions, including relief measures, implemented to address the impact of the pandemic, and resulting impacts on the financial markets and overall economy. The imposition of restrictions on business operations, travel and gatherings by state and federal governments in the United States as well as governments in other regions of the world in response to the COVID-19 pandemic initially placed significant strain on our clinical trial sites, raised concerns around monitoring patient safety, slowed patient enrollment and caused delays in the Company’s clinical trials and issuance of results. Any rise of COVID-19 infection rates, especially in the United States, could continue to negatively affect enrollment going forward. We continue to closely monitor the COVID-19 situation and any potential impact to our planned activities.
Financial Overview
Since commencing operations in 2015, we have devoted substantially all our efforts and financial resources to organizing and staffing our company, identifying business development opportunities, raising capital, securing intellectual property rights related to our product candidates, building and optimizing our manufacturing capabilities, and conducting discovery, research and development activities for our product candidates, discovery programs and FIND-IO platform.
We have not generated any revenue from product sales and only limited revenue from other sources. Our net loss for the three months ended September 30, 2022 and 2021, was $18.9 million and $17.9 million, respectively, and our net loss for the nine months ended September 30, 2022 and 2021, was $57.4 million and $52.5 million, respectively. As of September 30, 2022, we had an accumulated deficit of $244.5 million, primarily as a result of research and development and general and administrative expenses. We do not expect to generate product revenue unless and until we obtain marketing approval and commercialize a product candidate, and we cannot assure you that we will ever generate significant revenue or profits.
We have funded our operations to date primarily with proceeds from public offerings of our common stock, with private placements of our preferred stock and with upfront fees received under our former research and development collaboration agreement with Lilly, or the “Lilly Agreement,” which was terminated in March 2020. From our inception through September 30, 2022, we received gross proceeds of $164.4 million through private placements of preferred stock.
In November 2018, we entered into the Lilly Agreement to use our FIND-IO platform to identify novel oncology targets for additional collaborative research and drug discovery by us and Lilly. We received an upfront payment of $25.0 million in cash and an equity investment of $15.0 million from Lilly upon entering into the Lilly Agreement. We were also eligible for quarterly research and development support payments during a portion of the term of the Lilly Agreement. Effective March 3, 2020, Lilly terminated the Lilly Agreement without cause.
On May 13, 2019, we closed our initial public offering, or “IPO”, in which we sold 5,750,000 shares of common stock at a public offering price of $15.00 per share, for aggregate gross proceeds of $86.3 million. The net offering proceeds to us were approximately $77.0 million after deducting underwriting discounts and commissions of $6.0 million and offering expenses of $3.4 million.
On November 19, 2019, we completed an underwritten public offering, in which we issued and sold 4,077,192 shares of common stock at a public offering price of $36.75 per share. On December 2, 2019, the underwriters exercised in full their option to purchase an additional 611,578 shares of common stock at the public offering price of $36.75, for
