Subsequent Events	Note 9. Subsequent Events The Company has completed an evaluation of all subsequent events through May 30, 2025 , the date the unaudited condensed financial statements were issued, to ensure that these unaudited condensed financial statements include appropriate disclosure of events both recognized in the unaudited condensed financial statements and events which occurred but were not recognized in the unaudited condensed financial statements. In April 2025, the Company borrowed a total of $3.6 million from Prophase, a related party of the Company due to having common executives, pursuant to loan agreements between the Company and Prophase (the “Prophase April 2025 Loans”). The Prophase 2025 Loans bear interest at 6% per annum and are due in May 2025. Given that Prophase is a related party, the Company and Prophase have mutually agreed to defer repayment of the past due loans until a time that is mutually agreed upon by both parties. Additionally, in April 2025, the Company funded additional advances under the Third Amended Note, of $0.2 million. Pursuant to the Business Combination Agreement, on April 30, 2025, the Mergers were completed (see Note 1). In connection with the completion of the Mergers, the Amended Note issued to Iris (see Note 7) was netted as Iris and Liminatus are now one consolidated entity. Subsequent to the Business Combination, $3.4 million of the Prophase April 2025 Loans were converted into funds of the private investment into the combined company.	Note 9.
