3. Liquidity and Going Concern

The Company incurred a net loss of $(6.3) million for the six months ended June 30, 2023. The Company had an accumulated deficit of $473.5 million as of June 30, 2023. Additionally, the Company used net cash of $(8.6) million to fund its operating activities for the six months ended June 30, 2023. These factors raise substantial doubt about the Company’s ability to continue as a going concern.

To date, the Company’s operating losses have been funded primarily from outside sources of invested capital from issuance of its common and preferred stocks, proceeds from its term loan and grant funding. However, the Company has had, and will continue to have, an ongoing need to raise additional cash from outside sources to fund its future clinical development programs and other operations. There can be no assurance that the Company will be able to continue to raise additional capital in the future. The Company’s inability to raise additional cash would have a material and adverse impact on its operations and would cause the Company to default on its term loan.

On May 24, 2022, the Company received notice from The Nasdaq Stock Market LLC (“Nasdaq”) that, because the closing bid price for the Company’s common stock had fallen below $1.00 per share for 30 consecutive business days, the Company no longer complied with the minimum bid price requirement pursuant to Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Requirement”).
