​ As of December 31, 2022 and 2021, the Company had deferred tax assets of approximately $4.4 million and $30.8 million, respectively. Realization of the deferred tax assets is primarily dependent upon future taxable income, if any, the amount and timing of which are uncertain. The Company has had significant pre-tax losses since its inception. The Company has not yet generated revenues and faces significant challenges to becoming profitable. Accordingly, the deferred tax assets have been fully offset by a valuation allowance of $4.4 million and $30.8 million as of December 31, 2022 and 2021, respectively. U.S. deferred tax assets will continue to require a valuation allowance until the Company can demonstrate their realizability through sustained profitability or another source of income. As of December 31, 2022 and 2021, the Company’s federal net operating loss carryforwards were approximately $1.5 million and $81.8 million, respectively. The Company had federal research credit carryforwards as of December 31, 2022 and 2021 of approximately $24 thousand and $1.0 million, respectively. The Federal net operating losses were incurred after December 31, 2017 and therefore, will not expire. As of December 31, 2022 and 2021, the Company had state net operating loss carryforwards of approximately $65 thousand and $42.6 million, respectively. The Company had state research credit carryforwards of $2 thousand and $0.6 million as of December 31, 2022 and 2021, respectively. The state net operating loss carryforwards and state research credit carryforwards will begin to expire in 2043, if not utilized. Lastly, the Company had foreign net operating loss carryforwards of approximately $0.7 million and $1.3 million as of December 31, 2022 and 2021, respectively. The foreign net operating loss carryforwards will begin to expire in 2028. Utilization of the net operating loss carryforwards and credits may be subject to a substantial annual limitation due to the ownership change limitations provided by Section 382 of the Internal Revenue Code of 1986, as amended, and similar state provisions. Generally, in addition to certain entity reorganizations, the limitation applies when one or more “5-percent shareholders” increase their ownership, in the aggregate, by more than 50 percentage points over a 36-month testing period, or beginning the day after the most recent ownership change, if shorter. The annual limitation may result in the expiration of net operating losses and credits before utilization. As a result of the public stock offering and private placement offering during the fourth quarter of 2022, a Section 382 ownership change occurred with an annual limitation of $0. Because of the 2022 ownership change and corresponding limitation, approximately $99.0 million and $48.5 million of federal and state net operating loss carryforwards, respectively, were written off, with a corresponding offset to the Company's full valuation allowance. Additionally, approximately $1.2 million and $0.6 million of federal and state research credit carryforwards, respectively, were written off, with a corresponding offset to the Company's full valuation allowance. ​ The Company recognizes interest and/or penalties related to uncertain tax positions in income tax expense. There were no uncertain tax positions as of December 31, 2022 and 2021, and as such, no interest or penalties were recorded to income tax expense. The Company’s corporate returns are subject to examination beginning with the 2018 tax year for federal and state jurisdictions, and beginning with the 2019 tax year for one foreign jurisdiction.
