Monopar and NorthStar Partner with IsoTherapeutics for the Manufacturing of Potential Therapeutic for Severe COVID-19

WILMETTE, Ill. and BELOIT, Wis. and ANGLETON, Texas, Aug. 10, 2020 (GLOBE NEWSWIRE) — Monopar Therapeutics Inc. (Nasdaq: MNPR) (Wilmette, IL) and NorthStar Medical Radioisotopes, LLC (Beloit, WI), who are collaborating on the development of Radio-Immuno-Therapeutics (RITs) to treat patients with severe COVID-19, today announced a partnership with IsoTherapeutics Group, LLC (Angleton, TX), to develop and manufacture a RIT for the potential treatment of severe COVID-19.
IsoTherapeutics will modify Monopar’s proprietary urokinase plasminogen activator receptor (uPAR) targeted antibody, MNPR-101, by making conjugates that will allow the attachment of therapeutic radioisotopes supplied by NorthStar, creating a platform of uPAR-targeted RIT (uPRIT) candidates to be evaluated as treatments for severe COVID-19.  The plan is for IsoTherapeutics to then advance a clinical candidate identified from this platform through GMP manufacturing for Monopar and NorthStar to take into its first in human trials.Recent publications have implicated uPAR-expressing immune cells in the development of severe lung injury, multiple organ failure, and death in severe COVID-19 patients. “A treatment that specifically targets and eradicates these over-activated immune cells could significantly improve patient outcomes in severe COVID-19,” said Andrew Mazar, Ph.D., Chief Scientific Officer of Monopar.“We are excited to partner with Monopar and NorthStar,” said Jim Simón, Ph.D., Chief Scientific Officer of IsoTherapeutics. “A uPAR-targeted RIT has great therapeutic potential, and we are proud to contribute our expertise in radiopharmaceutical research and manufacturing to ensure its rapid and effective development.”James T. Harvey, Ph.D., Senior Vice President and Chief Science Officer of NorthStar, said “We have successfully worked with IsoTherapeutics on a previous project that led to an FDA approval, and we value their expertise. This is a crucial step in the development of a uPRIT for severe COVID-19.”About Monopar Therapeutics Inc.Monopar Therapeutics is a clinical-stage biopharmaceutical company primarily focused on developing proprietary therapeutics designed to extend life or improve the quality of life for cancer patients.

Examples of these forward-looking statements include statements concerning IsoTherapeutics’ ability to create a platform of uPAR-targeted RIT (uPRIT) candidates based upon MNPR-101 and  a therapeutic radioisotope from NorthStar; IsoTherapeutics’ ability to advance a clinical candidate identified from this platform through GMP manufacturing for Monopar and NorthStar to take into its first in human trials; that a treatment that specifically targets and eradicates these over-activated immune cells could significantly improve patient outcomes in severe COVID-19; that a uPAR-targeted RIT has great therapeutic potential; and that IsoTherapeutics’ expertise in radiopharmaceutical research and manufacturing will ensure rapid and effective development of uPRIT candidates. 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, the requirement for additional capital to complete preclinical and clinical development, and if successful, commercialization, IsoTherapeutics not being able to couple MNPR-101 to a therapeutic radioisotope, the conjugate not being able to kill aberrantly activated cytokine-producing immune cells, the conjugate not being able to use uPAR to gain entry into these cells and deliver cytotoxic payload to kill these cells while sparing normal 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. Risks are described more fully in Monopar’s filings with the Securities and Exchange Commission.
