Related Party Transactions Disclosure [Text Block] | Note 6 - Related Party Transactions Introgen Research Institute Introgen Research Institute (“IRI”) is a Texas-based technology company formed by Rodney Varner, who prior to his passing in May 2024, was the Company’s President, Chief Executive Officer and Chairman of the Board and who was IRI’s sole officer. IRI is owned by trusts of which Mr. Varner's descendants are the sole beneficiaries. In April 2009, prior to Mr. Varner becoming an officer and director of Genprex in August 2012, the Company entered into an Assignment and Collaboration Agreement with IRI, providing Genprex with the exclusive right to commercialize a portfolio of intellectual property. This agreement was amended in 2011 to include additional sublicensing of additional intellectual property made available to IRI from MD Anderson (see Note 7 – Commitments and Contingences – Commitments – MD Anderson Cancer Center). There were no amounts incurred or due under this agreement at September 30, 2025 and December 31, 2024.
