Note 4. Accounts Payable and Accrued Expenses
Accounts payable and accrued expenses totaled $2.5 million as of September 30, 2025, compared to $1.4 million as of December 31, 2024. The increase was primarily attributable to the timing of vendor invoicing and payments and higher accrued research and development expenses related to ongoing ONP-002 program activities during the quarter.
These liabilities consist primarily of account payables to research and development vendors, payroll and benefits accruals, professional service fees, and other general corporate obligations. As of September 30, 2025, this balance also included a $700,000 accrual related to the Ladenburg Thalmann legal settlement, which was paid in October 2025 in full satisfaction of the matter (see Note 10. Commitments and Contingencies).
As of September 30, 2025, the Company had entered into several research and development service agreements not yet invoiced; such commitments are expected to be recognized as expenses in future periods as services are performed.
