General and Administrative Expenses
General and administrative expenses for the six months ended June 30, 2024 were $3,265.1 thousand, compared to $3,681.2 thousand for the six months ended June 30, 2023. The $416.1 thousand decrease was primarily attributable to a $507.3 thousand decrease in professional fees, resulting from lower legal and PR/IR costs incurred to date in 2024, offset by an increase of $213.4 thousand in employee related costs, primarily from increased headcount year-over-year.
Financing Costs
Financing costs were $1,346.1 thousand for the six months ended June 30, 2024. We did not incur any financing costs for the six months ended June 30, 2023. The $1,346.1 thousand increase was attributable to issuance costs as well as changes in derivative fair value associated with our ELOC financing with the ELOC Purchaser, described further below.
Change in Fair Value of Warrants
Change in fair value of warrants was a gain of $10,761.0 thousand for the six months ended June 30, 2024. There was no change in fair for the six months ended June 30, 2023. This increase was attributable to the fair value remeasurement with respect to our liability-classified Canaccord Warrants during 2024. The associated gain recorded in Results of Operations was primarily driven by the decrease in our stock price during 2024, which caused the fair value of the liability to decrease.
Interest Income
Interest income was $70.1 thousand for the six months ended June 30, 2024. Interest income was $455.1 thousand for the six months ended June 30, 2023. The decrease of $385.0 thousand was the result of lower cash and cash equivalent balances when compared to the prior year period.
Liquidity and Capital Resources
Since our inception in 2008, we have devoted most of our cash resources to research and development and general and administrative activities. We have financed our operations primarily with the proceeds from the sale of common stock and warrants. To date, we have not generated any revenue from the sale of products, and we do not anticipate generating any revenue from the sale of products for the foreseeable future. We have incurred losses and generated negative cash flows from operations since inception. As of June 30, 2024, our principal source of liquidity was our cash and cash equivalents, which totaled $3,997.8 thousand. We do not believe that our cash on hand will be sufficient to fund our operations for at least twelve months beyond the date of this filing.
2024 ELOC Purchase Agreement
On April 25, 2024, we entered into an ELOC Purchase Agreement with the ELOC Purchaser, whereby we may offer and sell, from time to time at our sole discretion, and whereby the ELOC Purchaser has committed to purchase, up to 2,051,428 shares of shares of our common stock. The term of the agreement runs until the expiration of our active S-3 Registration Statement, unless earlier terminated or exhausted.
Upon execution of the ELOC Purchase Agreement, we agreed to issue 33,937 shares of common stock as commitment shares to the ELOC Purchaser. In addition to the commitment shares referenced above, we sold 700.0 thousand shares of our common stock under the purchase agreement and received net proceeds of $4,236.0 thousand. No shares were issued under the purchase agreement prior to the second quarter of 2024. The ELOC Purchaser has agreed that during the term of the Purchase Agreement, neither it nor any of its affiliates will engage in any short sales or hedging transactions involving the Company’s common stock.
