Monopar Therapeutics Reports First Quarter 2024 Financial Results and Strategic Focus on its Radiopharma Pipeline

Initiated MNPR-101-Zr First-in-Human Phase 1 Radiopharma Clinical Trial

MNPR-101-RIT Phase 1 Clinical Trial Targeted for Launch as Early as Q4 2024 or Q1 2025

WILMETTE, Ill., May 09, 2024 (GLOBE NEWSWIRE) -- Monopar Therapeutics Inc. (Monopar or the Company) (Nasdaq: MNPR), a clinical-stage radiopharmaceutical company focused on developing innovative treatments for cancer patients, today announced first quarter 2024 financial results and summarized recent developments.

Recent Developments

The radiopharma space has had numerous positive recent developments and announcements, from acquisitions to clinical data to reimbursement rates to commercial demand. Since this past December alone, four significant acquisitions have been publicly announced or completed which have had upfront payments ranging from approximately $1 billion to over $4 billion (BMS/RayzeBio, AstraZeneca/Fusion Pharma, Eli Lilly/POINT BioPharma, and Novartis/ Mariana Oncology).

Monopar has been generating promising preclinical data, and recently entered the clinic with its novel, proprietary MNPR-101 radiopharma program targeting the urokinase plasminogen activator receptor (uPAR). Based on these advances, Monopar has made the strategic decision to focus its resources on the assets and capabilities it has been building up in the radiopharma space. As such, the Company is winding down its non-radiopharma programs, including camsirubicin (and its Phase 1b clinical trial) as well as MNPR-202. The Company is targeting launching its second radiopharma clinical trial as early as the end of this year or the first quarter of 2025.

MNPR-101 for Radiopharmaceutical Use – First-in-Human Study with MNPR-101-Zr is Now Active

• Received clearance and recently initiated a first-in-human Phase 1 imaging and dosimetry clinical trial with novel radiopharmaceutical MNPR-101-Zr in advanced cancer patients. Further information about the MNPR-101-Zr trial is available at www.ClinicalTrials.gov under study identifier NCT06337084. This study is being led by internationally recognized radiopharmaceutical physician Prof. Rodney Hicks, founder of the Melbourne Theranostic Innovation Centre (MTIC).

• Optimized imaging and therapeutic MNPR-101 radiopharma programs, significantly increasing tumor uptake while minimizing uptake in healthy tissue (link). This work led to in vivo efficacy studies demonstrating near complete elimination of the tumor after a single injection of the MNPR-101 radiopharmaceutical agent.

• Imaged the biodistribution of a therapeutic radioisotope bound to MNPR-101, and demonstrated highly preferential tumor uptake in the tumor consistent with what is seen with the Zr-89 imaging radioisotope (link).

• Filed a provisional patent application to protect the recent advancements and optimizations Monopar has achieved with its MNPR-101 radiopharma programs.

• Announced that Monopar’s abstract on MNPR-101-Zr radiopharma program was selected for presentation at the Society of Nuclear Medicine and Molecular Imaging’s Annual Meeting on June 8-11, 2024.

• Monopar is targeting initiating a Phase 1 clinical study in advanced cancers with its therapeutic radiopharmaceutical MNPR-101-RIT as soon as the end of this year or early next year.
