WILMETTE, Ill., Dec. 05, 2024 (GLOBE NEWSWIRE) -- Monopar Therapeutics Inc. (Nasdaq: MNPR), a clinical-stage biotechnology company focused on developing innovative treatments for patients with unmet medical needs, today announced the first patient ever dosed with MNPR-101-Lu. This novel therapeutic radiopharmaceutical combines MNPR-101, Monopar’s antibody that selectively targets the urokinase plasminogen activator receptor (uPAR), with the therapeutic radioisotope lutetium-177. uPAR is involved in tumor growth and metastasis, and is found in some of the most aggressive, deadly cancers, including pancreatic, ovarian, triple negative breast, and colorectal cancers.
The MNPR-101-Lu intravenous infusion was well-tolerated with no serious adverse reactions reported. This patient, dosed under a compassionate use protocol in the US, has metastatic pancreatic cancer, and prior to dosing, the cancer was imaged using MNPR-101-Zr (a zirconium-89 imaging radioisotope conjugated to MNPR-101) with a PET/CT scanner and showed uPAR expression.
“As a result of encouraging biodistribution and dosimetry clinical data we recently reported (link) with our radiodiagnostic, MNPR-101-Zr, we have been eagerly looking forward to initiating treatment of patients with MNPR-101-Lu, hopeful it may provide an important therapeutic benefit to a group of cancer patients very much in need,” said Chandler Robinson, MD, Monopar’s Chief Executive Officer.
“We are thrilled to have dosed this patient with MNPR-101-Lu, and believe this may be the world’s first dosing of a patient with a uPAR-targeted therapeutic radiopharmaceutical,” said Andrew Cittadine, Monopar’s Chief Operating Officer.
Monopar is actively enrolling participants in two Phase 1 clinical studies in Australia, evaluating MNPR-101-Zr for imaging and MNPR-101-Lu for treatment of advanced solid tumors. Further information about the MNPR-101-Lu Phase 1a trial is available at www.ClinicalTrials.gov under study identifier NCT06617169. Further information about the MNPR-101-Zr Phase 1 imaging and dosimetry clinical trial is available at www.ClinicalTrials.gov under study identifier NCT06337084.
