MNPR-101-Zr FDA Regulatory Timeline and Events
MNPR-101-Zr is a drug developed by Monopar Therapeutics for the following indication: In Advanced Cancer Patients.
This drug is under review by the U.S. Food and Drug Administration (FDA).
Below is a timeline of key regulatory milestones for this therapy.
- Drug:
- MNPR-101-Zr
- Announced Date:
- June 11, 2025
- Indication:
- In Advanced Cancer Patients
Announcement
Monopar Therapeutics Inc. 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").
AI Summary
Monopar Therapeutics Inc. announced that it has received FDA approval to proceed with its physician-sponsored Expanded Access Program (EAP) for the investigational products MNPR-101-Zr and MNPR-101-Lu. These agents are designed to help image and treat advanced solid tumors, including aggressive forms of cancer like triple-negative breast, pancreatic, and colorectal cancers. The study will be conducted at the Excel Diagnostics and Nuclear Oncology Center (EDNOC) in Houston, Texas, where patients with advanced solid tumors can now enroll under the EAP.
The program offers a way for patients with serious or life-threatening conditions to access these new treatments outside of clinical trials when no other options are available. The initiative is led by expert Dr. Ebrahim S. Delpassand, aiming to advance the use of targeted radiopharmaceuticals in cancer care while closely monitoring safety and effectiveness as the therapy moves towards wider use.

- MNPR-101-Zr
- Announced Date:
- September 12, 2024
- Indication:
- In Advanced Cancer Patients
Announcement
Monopar Therapeutics Inc. announced positive early data from its ongoing open-label MNPR-101-Zr Phase 1 imaging and dosimetry clinical trial confirming MNPR-101-Zr's tumor targeting ability in humans.
AI Summary
Monopar Therapeutics announced encouraging results from its MNPR-101-Zr Phase 1 imaging and dosimetry trial, confirming the drug’s ability to target tumors in humans. MNPR-101-Zr pairs a specialized humanized monoclonal antibody with a radioactive zirconium label to seek out cancer cells. In one patient, PET imaging taken seven days after treatment clearly showed that MNPR-101-Zr was concentrated in tumor areas, distinguishing them from normal tissue.
These findings support the promise of MNPR-101-Zr as a reliable imaging tool for cancers that express high levels of specific receptors. The targeted uptake observed in this early study could lead to better cancer detection and, ultimately, more effective treatments in the future.

Announcement
Monopar Therapeutics Inc. announced that its Phase 1 dosimetry clinical trial for its novel radiopharmaceutical imaging agent MNPR-101-Zr (MNPR-101 conjugated to zirconium-89) is now active and recruiting patients with advanced cancers.
AI Summary
Monopar Therapeutics Inc. has activated its Phase 1 dosimetry clinical trial for MNPR-101-Zr, a new radiopharmaceutical imaging agent designed for advanced cancer patients. This agent is MNPR-101 conjugated to zirconium-89 and targets the urokinase plasminogen activator receptor (uPAR), which is present on several tumor types such as pancreatic, breast, colorectal, and bladder cancers.
The study is being conducted at the Melbourne Theranostic Innovation Centre in Australia under the leadership of Professor Rodney Hicks. Using a cutting-edge Siemens Biograph Vision Quadra PET/CT scanner, the trial will evaluate how well MNPR-101-Zr targets tumors and its safety profile. Up to 12 advanced cancer patients will participate, and promising early data from preclinical studies has shown strong, specific tumor uptake. Positive results could pave the way for further trials with therapeutic radioisotopes for hard-to-treat cancers.
