Summary of Financial Results for the Full Year 2023
Research and development (R&D) expenses were $19.5 million and $19.0 million for the years ended December 31, 2023 and 2022, respectively. The increase in R&D of $0.5 million is mainly related to the $1.5 million WPD sublicense termination, which enabled the reacquisition of the Company's intellectual property rights in certain territories, including parts of the European Union. This was offset by $1.0 million in costs related to the timing of costs incurred for clinical trials and sponsored research.
General and administrative (G&A) expenses were $10.0 million and $11.5 million for the years ended December 31, 2023 and 2022, respectively. The decrease in G&A of $1.5 million was mainly attributable to a decrease in regulatory and legal services, and consulting & advisory fees.
The net loss for the year ended December 31, 2023 was $29.8 million, which included a non-cash loss of $1.0 million on warrants in 2023 as compared to a gain of $1.3 million in the prior year and approximately $2.0 million of stock-based compensation expense in 2023 as compared to $2.3 million in 2022.
As of December 31, 2023, the Company had cash and cash equivalents of $23.6 million. The Company believes that this cash is sufficient to meet its projected operating requirements into the fourth quarter of 2024.
