Summary of Significant Accounting Policies (Policies)	Sep. 30, 2025
Accounting Policies [Abstract]
Estimates	Estimates The preparation of condensed financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Actual results could differ from those estimates.
Revenue Recognition	Revenue Recognition The Company currently has no ongoing source of revenue. Miscellaneous income, including interest, is recognized when earned by the Company. Deferred revenue represents cash received for royalties in advance of being earned. Such payments are reflected as deferred revenue until recognized under the Company’s revenue recognition policy. Deferred revenue would be classified as current if management believes the Company will be able to recognize the deferred amount as revenue within twelve months of the balance sheet date. Deferred revenue will be recognized when the product is sold and the royalty is earned. Since all deferred revenue is related to the BCCNS product, which is yet to be approved by FDA, the Company has determined that 100% of the advances of the royalty received from Mayne Pharma Ventures Pty Ltd. (“Mayne Pharma”) should be classified as non-current. As of September 30, 2025 and December 31, 2024, deferred revenue consisted of $3 million of royalties advanced by Mayne Pharma under the Third Amended Supply and License Agreement (“SLA”).
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents. The Company maintains cash balances in bank accounts in excess of Federal Deposit Insurance Corporation insured amounts. The Company continues to monitor the third-party depository institutions that hold the Company’s cash and limits its cash deposits to financial institutions with high credit standing. The Company has not experienced any losses in these accounts to date.
Research and Development Expenses	Research and Development Expenses Research and development (“R&D”) costs are expensed in the period in which they are incurred and include salaries, benefits and other related costs to support the Company’s R&D operations, amounts paid to third parties who conduct research and development activities on behalf of the Company, as well as the costs of discovery research, preclinical and clinical development, drug formulation and licensing payments. Upfront and advanced licensing payments for future use in R&D activities are recorded as prepaid expenses and are expensed as the related services are performed.
General and Administrative Expenses	General and Administrative Expenses General and administrative (“G&A”) expenses are expensed in the period in which they are incurred and include operating expenses not classified as R&D expenses, such as salaries, benefits, insurance, board of directors’ fees, travel costs, as well as fees for professional services related to accounting, tax and legal matters.

Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based awards to employees and non-employees using a fair value-based method to determine compensation for all arrangements where shares of stock or equity instruments are issued for compensation. Fair values of restricted stock units issued are determined by the Company based predominantly on the trading price of the common stock on the date of grant. The fair value of each common stock option is estimated on the date of grant using the Black-Scholes valuation model that uses assumptions for expected volatility, expected dividends, expected term, and the risk-free interest rate. Expected volatility is based on historical volatility of a peer group’s common stock and other factors estimated over the expected term of the options. The expected term of the options granted is derived using the “simplified method” which computes the expected term as the average of the weighted-average vesting term and the contract term. The risk-free rate is based on the U.S. Treasury yield.
Income Taxes	Income Taxes Deferred tax assets and liabilities are recognized for future tax consequences attributed to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and are measured using enacted tax rates that are expected to apply to the differences in the periods that they are expected to reverse.
Leases	Leases The Company recognizes on its balance sheet right-of-use assets and lease liabilities associated with lease agreements based on the present value of the future lease payments over the contractual lease term using its incremental borrowing rate on the lease commencement date. The Company has elected not to recognize a lease liability or right-of-use asset on the balance sheet for leases with an initial term of 12 months or less. Operating lease expenses on capitalized leases and short-term leases are recognized on a straight-line basis over the respective lease term, inclusive of rent escalation provisions and rent abatements, as a component of general and administrative expenses in the statements of operations.
Reclassifications	Reclassifications Certain prior period amounts have been reclassified to conform to current period presentation. The reclassifications relate to such expenses incurred by the Company that were reclassified from G&A expenses to R&D expenses to better align with the nature of the expenditures. The reclassifications had no impact on the Company’s previously reported financial position, results of operations or cash flows.
Recent accounting pronouncements	Recent accounting pronouncements Management has considered all recent accounting pronouncements issued, but not effective, and does not believe that any will have a material impact on the Company’s results of operations or financial position.
