WILMETTE, Ill., April 16, 2024 (GLOBE NEWSWIRE) -- Monopar Therapeutics Inc. (Nasdaq: MNPR), a clinical-stage biopharmaceutical company focused on developing innovative treatments for cancer patients, today announced that it has filed a provisional patent application pertaining to the recent advancements and optimizations Monopar has achieved with its MNPR-101 radiopharmaceutical program.

The provisional patent titled "Antibody Radioisotope Constructs" that was filed with the United States Patent and Trademark Office (USPTO) outlines the MNPR-101-Zr construct, including variations on the radioisotopes, linkers, and antibody which could enhance the clinical profile of the construct, including properties such as its stability and biodistribution. It also covers the formulations and uses of MNPR-101-Zr, a zirconium-89 imaging radioisotope labeled version of MNPR-101, Monopar's proprietary first-in-class humanized monoclonal antibody that is highly-selective against the urokinase plasminogen activator receptor (uPAR).

Monopar expects this provisional patent application to further strengthen its intellectual property around the MNPR-101 radiopharma program, under which the Company is aiming to develop therapies for numerous hard-to-treat advanced cancers that express uPAR. Monopar recently announced the initiation of its Phase 1 dosimetry clinical trial for MNPR-101-Zr in patients with advanced cancers.

"Filing of this provisional patent application is aimed at further protecting our novel MNPR-101 radiopharmaceutical program," said Chandler Robinson, MD, Monopar's Chief Executive Officer. "This patent filing along with our earlier patent filings helps to create a broad portfolio of intellectual property around this program and potential future programs."
