Research and Development Activity [Abstract] |
RESEARCH AND DEVELOPMENT ACTIVITY | NOTE 4 – RESEARCH AND DEVELOPMENT ACTIVITY According to AUS tax law, the Company is allowed an R&D tax credit that reduces a company’s tax bill in AUS for expenses incurred in R&D subject to certain requirements. The Company’s Australian subsidiary submits R&D tax credit requests annually for research and development expenses incurred. At September 30, 2025 and December 31, 2024, the Company recorded a research and development tax credit receivable of $1,704,000 and $1,181,000, respectively, for R&D expenses incurred in Australia. Xencor, Inc. License Agreement On October 3, 2017, the Company entered into a license agreement (“Xencor License Agreement”) with Xencor, Inc. (“Xencor”), which discovered and developed a proprietary biological molecule that inhibits soluble tumor necrosis factor. On June 10, 2021, the Company and Xencor entered into a First Amendment to License Agreement pursuant to which, among other things, Section 3.2 of the Xencor License Agreement was amended to change the due diligence milestones. Pursuant to the Xencor License Agreement, Xencor granted the Company an exclusive worldwide, royalty-bearing license in licensed patent rights, licensed know-how and licensed materials (as defined in the license agreement) to make, develop, use, sell and import any pharmaceutical product that comprises, contains, or incorporates Xencor’s proprietary protein known as “XPro” that inhibits soluble tumor necrosis factor (or all modifications, formulations and variants of the licensed protein that specifically bind soluble tumor necrosis factor) alone or in combination with one or more active ingredients, in any dosage or formulation (“Licensed Products”). The Company believes the protein has numerous medical applications. Such additional alternative applications of the technology are available under the Xencor License Agreement. The Company also agreed to pay Xencor a 5% royalty on Net Sales of all Licensed Products in a given calendar year, which are payable on a country-by- country and licensed product by licensed product basis until the date that is the later of (a) the expiration of the last to expire valid claim covering such Licensed Product in such country or (b) ten years following the first sale to a third party of the licensed product in such country. During the second quarter of 2025, the Company released the Phase 2 clinical trial results for our Alzheimer’s drug candidate, XPro, which failed to meet the primary endpoint, though a subgroup showed potential benefits. Due to insufficient resources to fund further trials, the Company has halted immediate plans to develop XPro for Alzheimer’s or other indications and are instead seeking a partner to continue these studies. As part of preparing its interim unaudited condensed consolidated financial statements, the Company determined that the intangible asset’s fair value was likely below its carrying value. Following a quantitative impairment assessment, the Company estimated the asset’s fair value at $0, resulting in a recorded impairment of $16,514,000 during the second quarter of 2025. CORDStrom License Agreement On February 6, 2025, the Company and Great Ormond Street Hospital for Children NHS Foundation Trust (“GOSH”) entered into a license agreement for the exclusive commercial use to clinical trial data associated with a GOSH study investigating the potential of CORDStrom to treat RDEB in pediatric patients (the “MissionEB study”). The Company owns the intellectual property covering CORDStrom, the investigational medicinal product used in the Mission EB study. In addition, the Company owns intellectual property and maintains trade secret protections covering the manufacturing of CORDStrom. With this license to the clinical trial data, the Company intends to prepare applications seeking marketing authorization of CORDStrom for treatment of pediatric RDEB in each of the FDA, EMA, and MHRA. Terms of the license agreement include a milestone payment of up to £6,000,000 (approximately $8.1 million as of September 30, 2025) due on the first to occur marketing authorization to be granted by the FDA, EMA or MHRA, which had not occurred as of September 30, 2025. The Company was also required to make an upfront payment to GOSH of approximately $0.3 million, which the Company paid during July 2025 and recorded in research and development expense. Pursuant to the GOSH license agreement, the Company has an obligation to provide CORDStrom to the MissionEB study at no cost. While Part 1 of the study is completed, Part 2 of the MissionEB study is currently uninitiated due to a lack of funding by the National Health Services England (“NHSE”). It is unknown whether funding for the study will be allocated by NHSE or its successor agency in the United Kingdom. The Company has not recorded an estimated obligation for the supply of the MissionEB trial with CORDStrom as it is unknown if the MissionEB trial will resume. INKmune License Agreement On October 29, 2015, the Company entered into an exclusive license agreement (the “INKmune License Agreement”) with Immune Ventures, LLC (“Immune Ventures”). Pursuant to the INKmune License Agreement, the Company was granted exclusive worldwide rights to the patents, including rights to incorporate any improvements or additions to the patents that may be developed in the future. In consideration for the patent rights, the Company agreed to the following milestone payments:
(in thousands) |  |  |
Each Phase I initiation |  | $ | 25 |
Each Phase II initiation |  | $ | 250 |
Each Phase III initiation |  | $ | 350 |
Each NDA/EMA filing |  | $ | 1,000 |
Each NDA/EMA awarded |  | $ | 9,000 |
In addition, the Company agreed to pay the licensor a royalty of 1% of net sales during the life of each patent granted to the Company. The License is owned by Immune Ventures. David Moss, the Company’s Chief Executive Officer, Mark Lowdell, its Chief Scientific Officer, and RJ Tesi, former Chief Executive Officer of the Company, are the owners of Immune Ventures. No sales have occurred under this license. During December 2023, the Company initiated a Phase I trial with INKmune in patients with metastatic castration-resistant prostate cancer. At December 31, 2024 and September 30, 2025, the Company recorded $25,000 payable to Immune Ventures within accounts payable and accrued liabilities – related parties in the consolidated balance sheet. The term of the agreement began on October 29, 2015 and ends on a country-by-country basis on the date of the expiration of the last to expire patent rights where patent rights exists, unless terminated earlier in accordance with the agreement. Upon the termination of the agreement, we shall have a fully paid up, perpetual, royalty-free license without further obligation to Immune Ventures. The agreement can be terminated by Immune Ventures if, after 60 days from the Company’s receipt of notice that the Company has not made a payment under the agreement, and the Company still does not make this payment. On July 20, 2018 and October 30, 2020, the parties amended the agreement under which the Company was required achieve milestones pursuant to the agreement. On April 17, 2023, the parties executed an additional amendment to the agreement under which the Company removed the due diligence requirements to achieve reasonable commercial efforts to bring INKmune to market. This removed all requirements of clinical trial timelines and the filing timelines of an NDA or equivalent. All other provisions in the INKmune License Agreement shall continue in full force and effect. University of Pittsburg License Agreement On October 3, 2017, the Company entered into an Assignment and Assumption Agreement with Immune Ventures related to intellectual property licensed from the University of Pittsburgh. Pursuant to the Assignment and Assumption Agreement (“Assignment Agreement”), Immune Ventures assigned all of its rights, obligations and liabilities under an Exclusive License Agreement between the University of Pittsburgh – Of the Commonwealth System of Higher Education (“Licensor”) and Immune Ventures to INmune Bio (“Licensee”), (the “PITT Agreement”).

The Company owes annual maintenance fees under the PITT Agreement in the amount of $25,000 payable on June 26 of each year until the first commercial sale. At September 30, 2025, the Company owed the University of Pittsburgh $25,000 for annual maintenance fees. Upon first commercial sale of a product making use of the licensed technology under the PITT Agreement, the Licensee is required to pay royalties equal to 2.5% of Net Sales each calendar quarter. Moreover, under the PITT Agreement the Licensee is required to make milestone payments as follows:
(in thousands) |  |  |
Each Phase I initiation |  | $ | 50 |
Each Phase III initiation |  | $ | 500 |
First commercial sale of product making use of licensed technology |  | $ | 1,250 |
The PITT Agreement expires upon the earlier of: (i) expiration of the last claim of the Patent Rights (as defined in the PITT Agreement) forming the subject matter of the PITT Agreement; or (ii) the date that is 20 years from the effective date of the agreement (June 26, 2037).
