WILMETTE, Ill. and HOUSTON, Texas, June 11, 2025 (GLOBE NEWSWIRE) -- Monopar Therapeutics Inc. (“Monopar,” the “Company,” “us” and “our”) (Nasdaq: MNPR), a clinical-stage biopharmaceutical company focused on developing innovative treatments for patients with unmet medical needs, in collaboration with Excel Diagnostics and Nuclear Oncology Center (“EDNOC”), a premier diagnostic medical imaging and therapeutic nuclear medicine center, today announced that the physician-sponsored Expanded Access Program (“EAP”) for the investigational imaging agent MNPR-101-Zr and investigational therapeutic agent MNPR-101-Lu has received authorization to proceed from the U.S. Food and Drug Administration (“FDA”). The MNPR-101 EAP is now open for enrollment to patients with advanced solid tumors at EDNOC in Houston, Texas. EDNOC is among the first private outpatient facilities in the U.S. to be designated as a Radiopharmaceutical Therapy Center of Excellence by the Society of Nuclear Medicine and Molecular Imaging (“SNMMI”). Patients will be treated under the supervision of renowned investigator Ebrahim S. Delpassand, MD, founder and medical director of EDNOC. “We are pleased to provide patients in the United States with access to MNPR-101-Zr and MNPR-101-Lu, which were developed to target aggressive cancers, such as triple-negative breast, pancreatic, and colorectal cancer,” said Andrew Cittadine, Chief Operating Officer of Monopar. “This EAP represents continued progress in our radiopharmaceutical pipeline following last year’s initiation of Phase 1 clinical trials in Australia with MNPR-101-Zr and MNPR-101-Lu. We are grateful for the opportunity to work with Dr. Delpassand to make these therapies available to patients on a compassionate use basis,” added Mr. Cittadine. “Our team at Excel Diagnostics looks forward to providing MNPR-101-Zr and MNPR-101-Lu to patients in need,” said Dr. Delpassand. “Targeting uPAR-expressing solid tumors will be another promising frontier in radioligand therapy to help patients with ‘difficult-to-treat’ cancers,” continued Dr. Delpassand. About Expanded Access to MNPR-101-Zr and MNPR-101-Lu EAPs are intended to serve as a potential pathway for a patient with a serious or immediately life-threatening disease or condition to gain access to an investigational medical product outside of clinical trials preceding FDA approval; this occurs when no comparable or satisfactory alternative treatment is available, and the patient’s situation necessitates accessing an unapproved product outside of clinical trials. Healthcare providers and cancer patients who are interested in learning more about the MNPR-101-Zr and MNPR-101-Lu EAP, including eligibility criteria, can visit www.clinicaltrials.gov using the following links: NCT06980506 and NCT06980519 for the imaging and therapy EAP, respectively. About MNPR-101-Zr and MNPR-101-Lu MNPR-101 is Monopar’s proprietary antibody targeting the urokinase plasminogen activator receptor (“uPAR”), which is expressed in numerous tumor types, including pancreatic, breast, colorectal, ovarian, and bladder. By selectively targeting uPAR, Monopar aims to image tumors and deliver a targeted radiopharmaceutical therapy that kills cancer cells while minimizing damage to healthy tissue. MNPR-101-Zr is MNPR-101 conjugated to zirconium-89 and designed for the imaging of advanced cancers; MNPR-101-Lu is MNPR-101 conjugated to lutetium-177 and designed as an investigational treatment of advanced solid cancers. About Monopar Therapeutics Inc. Monopar Therapeutics is a clinical-stage biopharmaceutical company focused on advancing late-stage ALXN1840 for Wilson disease, and radiopharmaceutical programs including Phase 1-stage MNPR-101-Zr for imaging advanced cancers, and Phase 1a-stage MNPR-101-Lu and late preclinical-stage MNPR-101-Ac for the treatment of advanced cancers.
