Monopar Announces Publication Demonstrating Potential Utility of MNPR-101 as an Imaging Agent to Improve Surgical Outcomes in Bladder Cancer


WILMETTE, Ill., Feb. 11, 2021 (GLOBE NEWSWIRE) -- Monopar Therapeutics Inc. (Nasdaq: MNPR), a clinical-stage biopharmaceutical company primarily focused on developing proprietary therapeutics designed to extend life or improve the quality of life for cancer patients, today announced the publication of a peer-reviewed study in the European Journal of Cancer which shows the potential utility of MNPR-101 as a uPAR imaging agent to improve surgical outcomes in bladder cancer.

Using Monopar’s proprietary humanized uPAR antibody, MNPR-101, a multimodal imaging probe was developed and tested in vivo in human bladder cancer models. The publication reports that high expression of uPAR in bladder cancer is localized at the tumor periphery, suggesting that using a fluorescent-conjugated MNPR-101 probe might allow surgeons to better visualize the borders of the tumor, potentially resulting in more complete tumor resection and thereby minimizing relapse. Similar approaches have been utilized successfully in the resection of other tumor types, such as breast cancer.

Bladder cancer is often treated with transurethral resection to remove cancerous tissue; however, recurrence can occur in up to 78% of patients within 5 years. Up to 40% of recurrent cases develop muscle invasive disease, which has a poor prognosis and requires complete removal of the bladder. Many patients with muscle-invasive bladder cancer unfortunately go on to develop and succumb to metastatic disease.

“This novel MNPR-101 based imaging agent has promising utility in allowing surgeons to easily identify tumor margins during surgery,” said Andrew Mazar, PhD, Chief Scientific Officer of Monopar and a co-author of the publication. “Given the specificity of uPAR expression in bladder cancer versus normal bladder tissue, and its high expression at the border of the tumor, we believe imaging uPAR using MNPR-101 targeting could improve surgical outcomes and potentially reduce recurrence of the disease.”

“If confirmed in a clinical setting, an imaging probe based on MNPR-101 could result in a paradigm shift, altering how urologists survey and treat bladder cancer,” said Cornelis Sier, PhD, member of the Image-Guided Surgery group at Leiden University Medical Center (LUMC), and the principal investigator on the study.

Examples of these forward-looking statements include statements concerning the potential utility of MNPR-101 as a uPAR imaging agent, whether a MNPR-101 based imaging agent could improve surgical outcomes in bladder cancer and related matters. The forward-looking statements involve risks and uncertainties including, but not limited to; the lack of any clinical activities to date with respect to MNPR-101 and that preclinical development activities to date have been focused on the treatment of cancers and not medical devices; the requirement for additional capital to complete preclinical and clinical development of a medical device utilizing MNPR-101, and if successful, commercialization; if funding is available, not being able to develop MNPR-101 for use as a uPAR imaging agent in bladder cancer or any other indications; not being able to ensure volumes of MNPR-101 conjugates can be manufactured and scaled up to meet potential demand; uncertainties about levels of demand if and when a medical device is available for commercialization and the significant general risks and uncertainties surrounding the research, development, regulatory approval and commercialization of medical devices. Actual results may differ materially from those expressed or implied by such forward-looking statements. Risks are described more fully in Monopar's filings with the Securities and Exchange Commission.
