The public offering price of the shares sold in the IPO was $15.00 per share. The IPO closed on March 29, 2016, pursuant to which the Company sold 4,700,000 shares of its common stock. On April 26, 2016, the Company sold an additional 502,618 shares of its common stock to the underwriters upon partial exercise of their over-allotment option, at the initial offering price of $15.00 per share. The Company received aggregate net proceeds of approximately $70.6 million, after underwriting discounts, commissions and offering expenses. Immediately prior to the consummation of the IPO, all outstanding shares of convertible preferred stock were converted into common stock.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;margin:0pt 0pt 12pt 0pt;"><span style="font-style:italic;font-weight:bold;">Follow-on Public Offering</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;text-indent:36pt;margin:0pt;">In March 2018, the Company completed a follow-on public offering in which the Company sold 8,117,647 shares of common stock at a price of $8.50 per share, which included 1,058,823 shares issued pursuant to the underwriters’ exercise of their option to purchase additional shares of common stock. The aggregate net proceeds received by the Company from the offering were approximately $64.9 million, net of underwriting discounts and commissions and offering expenses payable by the Company.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;margin:0pt;"><span style="margin-bottom:6pt;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;margin:0pt 0pt 12pt 0pt;"><span style="font-style:italic;font-weight:bold;">Liquidity</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;margin:0pt;"><span style="display:inline-block;text-indent:0pt;width:36pt;"/>The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, protection of proprietary technology, dependence on key personnel, contract manufacturer and contract research organizations, compliance with government regulations and the need to obtain additional financing to fund operations. Since commencing operations in 2014, the majority of the Company’s efforts have been focused on the research and development of CPI-006, CPI-818 and ciforadenant. The Company believes that it will continue to expend substantial resources for the foreseeable future as it continues clinical development of, seek regulatory approval for and, if approved, prepare for the commercialization of ciforadenant, CPI-006, and CPI-818, as well as product candidates under the Company’s other development programs. These expenditures will include costs associated with research and development, conducting preclinical studies and clinical trials, obtaining regulatory approvals, manufacturing and supply, sales and marketing and general operations. In addition, other unanticipated costs may arise. Because the outcome of any clinical trial and/or regulatory approval process is highly uncertain, the Company may not be able to accurately estimate the actual amounts necessary to successfully complete the development, regulatory approval process and commercialization of CPI-006, CPI-818, and ciforadenant or any other product candidates. The Company does not expect its existing capital resources to be sufficient to enable it to fund the completion of its clinical trials and remaining </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;margin:0pt 0pt 12pt 0pt;"><span style="white-space:pre-wrap;">development program of CPI-006, CPI-818 and ciforadenant through commercialization. In addition, its operating plan may change as a result of many factors. </span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;margin:0pt 0pt 12pt 0pt;"><span style="display:inline-block;text-indent:0pt;width:36pt;"/>The Company has incurred significant losses and negative cash flows from operations in all periods since inception and had an accumulated deficit of $223.1 million as of December 31, 2020. The Company has historically financed its operations primarily through the sale of redeemable convertible preferred stock and common stock. While the Company has been able to raise multiple rounds of financing, there can be no assurance that in the event the Company requires additional financing, such financing will be available on terms which are favorable or at all. Failure to generate sufficient cash flows from operations, raise additional capital or reduce certain discretionary spending would have a material adverse effect on the Company’s ability to achieve its intended business objectives.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;margin:0pt 0pt 12pt 0pt;"><span style="display:inline-block;text-indent:0pt;width:36pt;"/>As of December 31, 2020, the Company had cash, cash equivalents and short-term marketable securities of $44.3 million. Management believes that the Company’s current cash, cash equivalents and short-term marketable securities will be sufficient to fund its planned operations for at least 12 months from the date of the issuance of these financial statements.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;margin:0pt 0pt 12pt 0pt;"><span style="display:inline-block;text-indent:0pt;width:36pt;"/>The current COVID-19 (coronavirus) pandemic, which is impacting worldwide economic activity, poses risks that the Company or its employees, contractors, suppliers, and other partners may be prevented from conducting business activities for an indefinite period of time, including due to shutdowns that may be requested or mandated by governmental authorities. The extent to which COVID-19 impacts the Company’s business, including its clinical trials and financial condition, will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the pandemic, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease. As COVID-19 continues to spread around the globe, we will likely experience disruptions, including delays or difficulties in enrolling patients in our clinical trials, delays or difficulties in clinical site initiation, interruption of key clinical trial activities, delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials and delays in necessary interactions with local regulatory authorities. COVID-19 may also impact the Company’s ability to raise additional capital on a timely basis or at all, which could negatively impact short-term and long-term liquidity.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;margin:0pt;"><span style="font-style:italic;font-weight:bold;">Exchange Warrants</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;text-indent:36pt;margin:0pt;"><span style="margin-bottom:6pt;visibility:hidden;"></span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">On November 8, 2019, the Company entered into an exchange agreement (the “Exchange Agreement”) with an investor and its affiliates (the “Exchanging Stockholders”), pursuant to which the Company exchanged an aggregate of 1,458,000 shares of the Company’s common stock, par value $0.0001 per share, owned by the Exchanging Stockholders for pre-funded warrants (the “Exchange Warrants”) to purchase an aggregate of 1,458,000 shares of common stock (subject to adjustment in the event of any stock dividends and splits, reverse stock split, recapitalization, reorganization or similar transaction, as described in the Exchange Warrants), with an exercise price of $0.0001 per share. The Exchange Warrants will expire <span style="white-space:pre-wrap;">ten years</span><span style="white-space:pre-wrap;"> from the date of issuance. The Exchange Warrants are exercisable at any time prior to expiration except that the Exchange Warrants cannot be exercised by the Exchanging Stockholders if, after giving effect thereto, the Exchanging Stockholders would beneficially own more than 9.99</span><span style="white-space:pre-wrap;">% of the Company’s common stock, subject to certain exceptions. In accordance with Accounting Standards Codification Topic 505, Equity, and Accounting Research Bulletin 43, the Company recorded the retirement of the common stock exchanged as a reduction of common shares outstanding and elected to record the excess over par value as a debit to additional paid-in-capital at the fair value of the Exchange Warrants on the issuance date. The Exchange Warrants are classified as equity in accordance with Accounting Standards Codification Topic 480, Distinguishing Liabilities from Equity, and Accounting Standards Codification Topic 815, Derivatives and Hedging, and the fair value of the Exchange Warrants was recorded as a credit to additional paid-in capital and is not subject to remeasurement. The Company determined that the fair value of the Exchange Warrants is substantially similar to the fair value of the retired shares on the issuance date due to the negligible exercise price for the Exchange Warrants. As of December 31, 2020, none of the Exchange Warrants have been exercised. </span></p>

Such deposits may, at times, exceed federally insured limits. The Company maintains its cash with an accredited financial institution and accordingly, such funds are subject to minimal credit risk. The Company’s marketable securities consist of investments in U.S. Treasury securities, U.S. government agency securities and corporate debt obligations, which can be subject to certain credit risks. However, the Company mitigates the risks by investing in high-grade instruments, limiting its exposure to any one issuer, and monitoring the ongoing creditworthiness of the financial institutions and issuers. The Company has not experienced any losses on its deposits of cash, cash equivalents or marketable securities.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;line-height:1.19;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The Company is subject to a number of risks similar to other early stage biopharmaceutical companies, including, but not limited to, the need to obtain adequate additional funding, possible failure of preclinical testing or clinical trials, its reliance on third parties to conduct its clinical trials, the need to obtain marketing approval for its product candidates, competitors developing new technological innovations, the need to successfully commercialize and gain market acceptance of the Company’s product candidates, its right to develop and commercialize its product candidates pursuant to the terms and conditions of the licenses granted to the Company, and protection of proprietary technology. If the Company does not successfully commercialize or partner any of its product candidates, it will be unable to generate product revenue or achieve profitability.</p>
