<p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;"><span style="font-style:italic;font-weight:bold;">Concentration of Credit Risk — </span>Financial instruments that potentially subject the Company to a significant concentration of credit risk consist of cash. The Company maintains its cash balances with one major commercial bank, JPMorgan Chase Bank. The balances are insured by the Federal Deposit Insurance Corporation (the “FDIC”) up to $250,000. As a result, as of December 31, 2021, approximately $23.5 million of its cash balance was not covered by the FDIC. As of December 31, 2020, the Company had approximately $13.8 million in cash on-hand, of which approximately $13.5 million was not covered by the FDIC. To date, the Company has not incurred any losses on its cash balances.</p> | |

<p style="font-family:'Times New Roman','Times','serif';font-size:10pt;margin:0pt 0pt 12pt 0pt;"><span style="font-style:italic;font-weight:bold;">Use of Estimates —</span> The preparation of consolidated financial statements in conformity with generally accepted accounting principles in the United States (“U.S.”) requires management to make estimates and assumptions that affect the amounts reported in the Company’s consolidated financial statements and accompanying notes. On an ongoing basis, the Company evaluates its estimates and judgments, which are based on historical and anticipated results and trends as well as on various other assumptions that the Company believes to be reasonable under the circumstances. By their nature, estimates are subject to an inherent degree of uncertainty and, as such, actual results may differ from the Company’s estimates. These estimates include accrued clinical trial costs, stock-based compensation expense, valuation of warrants and valuation of deferred tax assets.</p> | |
