Commitments and Contingencies Disclosure [Abstract] |
COMMITMENTS AND CONTINGENCIES | 6. COMMITMENTS AND CONTINGENCIES Legal From time to time, the Company is involved in legal actions and claims arising in the normal course of business. Management believes there are no matters which will have a material adverse effect on the Company’s financial position, operations or cash flows. Patent Licensing, Sponsored Research, and Patent & Technology Agreements Ateganosine (THIO) In November 2018 and as amended in December 2020, the Company entered into a Global Patent Licensing Agreement titled “Patent and Technology License Agreement AGT. NO. L2264 – MAIA Biotechnology” with the University of Texas Southwestern (“UTSW”) to license patent families for a specific compound (“THIO”) from UTSW to MAIA (the “UTSW Agreement”). The UTSW Agreement, as amended, has a term of 20 years. The agreement requires MAIA to reimburse UTSW for agreed-upon expenses related to THIO. The UTSW Agreement requires certain payments upon assignment of the license to a third party as well as upon reaching specific milestones, ranging between $1,000,000 and $50,000,000, not to exceed a combined milestone payment total of $112,000,000. As of June 30, 2026, no assignment has occurred and none of the defined milestones have been completed and therefore no payments are due to UTSW related to the milestones. The UTSW Agreement requires MAIA to make royalty payments of: (i) 2-4% (depending on THIO reaching specified sales levels in the respective jurisdictions) on net sales up to $1,000,000,000; and (ii) 2.5-5% on net sales above $1,000,000,000. Also in December 2020, the Company entered into a second license agreement with UTSW titled “Patent and Technology License Agreement AGT. NO. L3648 — MAIA Biotechnology” pursuant to which UTSW is licensing an additional compound to MAIA (the “UTSW2 Agreement”). The UTSW2 Agreement has a term of 20 years and requires the Company to reimburse UTSW for certain agreed-upon expenses. The UTSW2 Agreement requires certain payments upon assignment of the license to a third party as well as upon reaching specific milestones, ranging between $1,000,000 and $50,000,000, not to exceed a combined milestone payment total of $112,000,000. As of June 30, 2026, no assignment has occurred and none of the defined milestones have been completed and therefore no payments are due to UTSW related to the milestones. The UTSW2 Agreement requires MAIA to make royalty payments of: (i) 2-4% (depending on THIO reaching specified sales levels in the respective jurisdictions) on net sales up to $1,000,000,000; (ii) and 2.5-5% on net sales above $1,000,000,000. The Company will also pay UTSW running royalties on a yearly basis as a percentage of Net Sales (as defined in the UTSW2 Agreement) of the Company or its sublicensee. There are single digit royalty rates for licensed products and licensed services covered by a Valid Claim (as defined in the UTSW2 Agreement) and dependent on whether Net Sales are greater than or less than/equal to $1,000,000,000, with Net Sales above that amount commanding a slightly higher percentage. In each case, the royalty percentage is lower before patent issuance in each jurisdiction. In the event that the licensed product or licensed service is not covered by a Valid Claim, the running royalty rates are reduced by 50%. The royalty obligations continue on a country-by-country basis until the later of expiration of the last Valid Claim in each country or 10 years after the First Commercial Sale (as defined in UTSW2 Agreement) in each country. Regeneron In February 2021, the Company entered into a Drug Supply Agreement (the “Drug Supply Agreement”) with Regeneron Pharmaceuticals, Inc. (“Regeneron”) to perform one clinical trial for the treatment of patients with Non-Small Cell Lung Cancer (NSCLC) involving a Regeneron drug candidate that utilizes one of the Company’s compounds/agents. The Company is responsible for all costs of the study with Regeneron supplying their drug cemiplimab representing a cost savings for the Company, the first phase of which is expected to take approximately two years. The overall term of the agreement is for five years unless earlier terminated for certain reasons as defined in the agreement. Either party may terminate a study plan in the event that patient screening for the clinical study does not commence within 12 months after: (i) the Effective Date (as defined in the Drug Supply Agreement), with respect to the initial study; or (ii) the execution of the applicable study plan, with respect to each other study. If either party terminates a study plan, the Company shall reimburse Regeneron for the Regeneron product it received in connection with such study plan based on the actual out-of-pocket cost to Regeneron of such Regeneron product. As of June 30, 2026, neither party has terminated the agreement. BeOne In December 2024, the Company reached an agreement with BeOne Medicines, Ltd., (“BeOne”) to perform certain clinical trials for the treatment of patients with small cell lung cancer (SCLC), liver cancer (HCC), and colorectal cancer (CRC) involving a BeOne drug candidate that utilizes one of the Company’s compounds/agents. The Company is responsible for all costs of the study with BeOne supplying their drug tislelizumab representing a cost savings for the Company. The overall term of the agreement is for seven years unless earlier terminated for certain reasons as defined in the agreement. As of June 30, 2026, neither party has terminated the agreement. Roche In June 2025, the Company reached an agreement with F. Hoffman-La Roche Ltd, (“Roche”) to perform certain clinical trials for the treatment of patients with hard-to-treat cancers involving Roche’s checkpoint inhibitor, atezolizumab (Tecentriq®). The Company is responsible for all costs of the study with Roche supplying their drug atezolizumab representing a cost savings for the Company. The overall term of the agreement is for five years unless earlier terminated for certain reasons as defined in the agreement. As of June 30, 2026, neither party has terminated the agreement.
