Significant estimates and assumptions made in the accompanying consolidated financial statements include, but are not limited to, the accrual for research and development expenses, the valuation of warrant liabilities and embedded derivative liabilities. Actual results could differ from those estimates, and such differences could be material to the consolidated financial statements.</p>

Cash is deposited in checking and money market accounts at accredited financial institutions, which at times, may exceed federally insured limits. The short-term investment is deposited in a guaranteed certificate of deposit with an accredited financial institution that guarantees 100% of the original amount invested. Management believes that these financial institutions are financially sound, and, accordingly, minimal credit risk exists with respect to these high-quality financial institutions. As of December 31, 2023, the Company has not experienced any losses on its cash or short-term investments as a result of credit risk.</p>
