CHICAGO and BELOIT, Wis., June 30, 2020 (GLOBE NEWSWIRE) -- Monopar Therapeutics Inc. (Nasdaq: MNPR) (Chicago, IL) and NorthStar Medical Radioisotopes, LLC (Beloit, WI) announced today that a provisional patent application entitled “Precision Radioimmunotherapeutic Targeting of the Urokinase Plasminogen Activator Receptor (uPAR) for Treatment of Severe COVID-19 Disease” has been filed with the U.S. Patent and Trademark Office (USPTO).

This application covers novel compositions and uses of cytotoxic radioisotopes attached to antibodies that bind to uPAR, thereby creating precision targeted radiotherapeutics (uPRITs) for the treatment of severe COVID-19 and other respiratory diseases. Advanced COVID-19 patients frequently develop severe, life-threatening, pulmonary inflammation as a result of a viral induced cytokine storm. The development of this cytokine storm is associated with a high rate of mortality in severe COVID-19 patients, even with oxygen support and mechanical ventilation. uPRITs have been designed with the goal of selectively destroying the aberrantly activated white blood cells responsible for causing the cytokine storm. If successful, healthy tissue would be spared in the process as the uPAR target is primarily only present on this unique class of white blood cells and not in healthy tissue. The co-inventors of the provisional patent application are James Harvey, Chief Scientific Officer of NorthStar, and Andrew P. Mazar, Chief Scientific Officer of Monopar.

If granted, the patent would offer exclusivity to Monopar and NorthStar for the development and potential use of uPRITs in the treatment of severe COVID-19 and other respiratory diseases. This provisional patent application leverages the therapeutic radioisotope expertise of NorthStar and the translational expertise of Monopar to create a novel, targeted radioimmunotherapeutic. On June 16, 2020, Monopar and NorthStar announced a 50/50 collaboration to couple Monopar’s MNPR-101 uPAR targeting monoclonal antibody to a therapeutic radioisotope provided by NorthStar.

Forward-Looking Statements
Statements contained in this press release regarding matters that are not historical facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. The words “may,” “will,” “could,” “would,” “should,” “expect,” “plan,” “anticipate,” “intend,” “believe,” “estimate,” “predict,” “project,” “potential,” “continue,” “target” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain these identifying words. Examples of these forward-looking statements include statements concerning the collaboration’s ability to create precision targeted radiotherapeutics (uPRITs) for the treatment of severe COVID-19 and other respiratory diseases; and that the patent may be granted. The forward-looking statements involve risks and uncertainties including, but not limited to, whether or not the patent will be granted, the lack of any clinical activities to date with respect to MNPR-101 and that pre-clinical development activities to date have been focused on the treatment of cancers, the requirement for additional capital to complete preclinical and clinical development, and if successful, commercialization, not being able to couple MNPR-101 to a therapeutic radioisotope, the uPRITs may not selectively destroy the aberrantly activated white blood cells responsible for causing the cytokine storm while sparing healthy tissue, not being able to ensure volumes of this radioisotope can be manufactured and scaled up to meet potential demand, uncertainties about levels of demand if and when a treatment is available for commercialization and the significant general risks and uncertainties surrounding the research, development, regulatory approval and commercialization of therapeutics. Actual results may differ materially from those expressed or implied by such forward-looking statements. Monopar and NorthStar are not making any express or implied claims that uPRITs have the ability to eliminate or mitigate severe COVID-19 at this time. Risks are described more fully in Monopar’s filings with the Securities and Exchange Commission. All forward-looking statements contained in this press release speak only as of the date on which they were made. Monopar and NorthStar undertake no obligation to update such statements to reflect events that occur or circumstances that exist after the date on which they were made. Any forward-looking statements contained in this press release represent Monopar’s and NorthStar’s views only as of the date hereof and should not be relied upon as representing its views as of any subsequent date.
