WILMETTE, Ill., March 27, 2026 (GLOBE NEWSWIRE) -- Monopar Therapeutics Inc. (“Monopar,” the “Company,” “we”) (Nasdaq: MNPR), a clinical-stage biopharmaceutical company developing innovative treatments for patients with unmet medical needs, today announced the fourth quarter and full-year 2025 financial results and provided a summary of recent developments.

“2025 was a productive year for Monopar, marked by multiple ALXN1840 data presentations, an important publication, a strengthened balance sheet and continued progress toward a planned New Drug Application submission for ALXN1840 in Wilson disease,” said Chandler Robinson, MD, Chief Executive Officer of Monopar. “We also recently strengthened our leadership team with the addition of Susan Rodriguez as Chief Commercial and Strategy Officer as we prepare for the potential launch of ALXN1840. We are grateful to the Wilson disease patients and their families whose experiences have informed our efforts to advance ALXN1840.”

Recent Program Developments

ALXN1840 – NDA Submission Planned for Mid-2026 for Wilson Disease

Wilson disease is a rare genetic disorder characterized by impaired copper elimination, resulting in toxic accumulation in organs such as the liver and brain. ALXN1840 binds and mobilizes copper and has a novel mechanism of action as an albumin tripartite complex (“ATC”) activator that differentiates it from currently available first-line therapies.

Based on recent interactions with the U.S. Food and Drug Administration (“FDA”), Monopar plans to submit a New Drug Application (“NDA”) for ALXN1840 in mid-2026.

ALXN1840 updates:

  • EASL 2025: Presented pooled long-term efficacy and safety data (n=255; median treatment duration 2.63 years), with additional safety data (n=266) supporting a favorable safety profile, as a late-breaking abstract
  • ANA 2025: Presented data demonstrating long-term neurological benefit; the abstract was selected for oral and poster presentation and designated an “Abstract of Distinction”
  • Journal of Hepatology / AASLD 2025: Reported statistically significant improvement in copper balance, with sustained improvement in daily copper balance driven by increased fecal copper excretion
  • EL-PFDD: Attended externally led patient-focused drug development (“EL-PFDD”) meeting with the FDA on January 29, 2026. During the meeting, patients and caregivers described the burden of Wilson disease, shared their experience with the currently available treatments, and highlighted the urgent need for additional treatment options
  • Upcoming 2026 presentations: Abstracts accepted for presentation at EASL 2026 and the American Academy of Neurology (“AAN”) 2026 Annual Meeting, including:
    • Tiomolybdate choline stabilizes liver disease and improves neurological symptoms as well as quality of life in treatment-experienced Wilson disease patients (EASL 2026 oral presentation)
    • Greater clinical benefit with tiomolybdate choline versus standard-of-care in neurologic Wilson disease patients in the Phase 3 FoCus Trial (AAN 2026 late-breaking oral and poster presentation)

MNPR-101 Radiopharmaceutical Programs

MNPR-101-Zr (zirconium-89), MNPR-101-Lu (lutetium-177), and MNPR-101-Ac (actinium-225) target the urokinase plasminogen activator receptor (“uPAR”), which is expressed in multiple aggressive cancers, including triple-negative breast, colorectal, and pancreatic cancers.

MNPR-101 platform update:

  • Ongoing Phase 1 clinical activity in Australia for MNPR-101-Zr and MNPR-101-Lu
  • Investigational new drug ("IND") clearance received for MNPR-101-Lu to initiate a Phase 1 clinical trial in the US
  • FDA-authorized physician-sponsored Expanded Access Program at Excel Diagnostics and Nuclear Oncology Center (“EDNOC”) in Houston, Texas
  • Preclinical development of MNPR-101-Ac

Financings

In 2025, Monopar strengthened its balance sheet through the following financing activities:

  • Completed an underwritten public offering generating approximately $91.9 million, after a concurrent repurchase of common stock but before offering expenses

Results for the Fourth Quarter and Year Ended December 31, 2025, Compared to the Fourth Quarter and Year Ended December 31, 2024

Cash and Net Loss

Cash, cash equivalents and short-term investments as of December 31, 2025, were $140.4 million.

Monopar expects its current funds to support operations through at least December 31, 2027, including: (1) regulatory and potential commercial activities for ALXN1840; (2) continued development of MNPR-101 programs; and (3) internal research and development.

Net loss for the fourth quarter of 2025 was $5.2 million, or $0.61 per share, compared to $10.9 million, or $2.23 per share, for the fourth quarter of 2024.

Net loss for the year ended December 31, 2025, was $13.7 million, or $1.85 per share, compared to $15.6 million, or $4.11 per share, for the year ended December 31, 2024.

Research and Development (“R&D”) Expenses

R&D expenses for the fourth quarter of 2025 were $3.9 million compared to $9.9 million for the fourth quarter of 2024. The decrease was primarily due to the absence of one-time expenses incurred in connection with the in-licensing of ALXN1840 in 2024, partially offset by higher R&D personnel expenses (driven by increased headcount and compensation), increased clinical material and manufacturing costs for the ALXN1840 program, and higher other R&D expenses.

R&D expenses for the year ended December 31, 2025, were $9.9 million compared to $13.0 million for the year ended December 31, 2024. The decrease was primarily due to the absence of one-time expenses incurred in connection with the in-licensing of ALXN1840 in 2024, as well as lower radiopharmaceutical clinical trial costs reflecting a shift in focus following the in-licensing, partially offset by higher R&D personnel expenses (driven by increased headcount and compensation), increased clinical material and manufacturing costs for the ALXN1840 program, and higher other R&D expenses.

General and Administrative (“G&A”) Expenses

G&A expenses for the fourth quarter of 2025 were $2.2 million compared to $1.2 million for the fourth quarter of 2024. The increase was primarily due to higher Board of Directors (the “Board”) and G&A personnel expenses (including stock-based compensation and bonuses), higher patent legal fees, and other increases in G&A expenses.

G&A expenses for the year ended December 31, 2025, were $6.8 million compared to $3.2 million for the year ended December 31, 2024. The increase was primarily due to higher Board and G&A personnel expenses (including stock-based compensation and bonuses), higher patent legal fees, and other increases in G&A expenses.
