(“Monopar” or the “Company”) (Nasdaq: MNPR), a clinical‐stage biopharmaceutical company developing innovative treatments for patients with unmet medical needs, today announced second quarter 2026 financial results and provided business updates. Recent Program Developments ALXN1840 for Wilson Disease – Rolling NDA Submission Initiated On July 22, 2026, Monopar announced it had initiated the rolling submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for ALXN1840. The FDA authorized Monopar to submit the NDA on a rolling basis, allowing completed sections of the application to be submitted and reviewed while the Company finalizes the remaining sections. The Company anticipates completing the NDA submission within the next few months. On June 30, 2026, the FDA granted Rare Pediatric Disease (RPD) designation to ALXN1840. The FDA grants RPD designation to therapies intended to treat serious or life-threatening diseases that primarily affect children from birth to 18 years of age. The designation provides the Company with the potential at the time of NDA approval to receive a pediatric Priority Review Voucher (PRV), which can be used to obtain priority review of a subsequent marketing application or sold or transferred to another sponsor. On June 28, 2026, Monopar presented new analyses from the Phase 3 FoCus randomized controlled clinical trial of ALXN1840 (tiomolibdate choline, TMC) at the 12th Congress of the European Academy of Neurology (EAN 2026). The poster presentation, titled “Greater clinical benefit with tiomolibdate choline versus standard-of-care in neurologic Wilson disease patients in the Phase 3 FoCus Trial,” showed significant neurologic improvement over time and greater global clinical improvement versus standard-of-care therapy in Wilson disease patients with neurologic symptoms at baseline. An oral late-breaker presentation on April 19, 2026, at the American Academy of Neurology (AAN) Annual Meeting also highlighted new analyses from the Phase 3 FoCus trial demonstrating greater neurologic benefit with ALXN1840 compared with standard of care (SoC) in Wilson patients with neurologic symptoms. On May 29, 2026, Monopar presented Phase 2 ALXN1840-WD-205 data at the European Association for the Study of the Liver (EASL) Congress 2026. The oral presentation, titled “ALXN1840 (tiomolibdate choline) stabilizes liver disease and improves neurological symptoms as well as quality-of-life in treatment-experienced Wilson disease patients,” demonstrated that, in a heavily pre-treated Wilson disease population, ALXN1840 can stabilize liver disease and provide clinically meaningful improvements in neurologic symptoms and quality of life. These findings complement the increased copper mobilization and clinical improvement shown in the completed Phase 3 pivotal trial (Study WTX101-301). On May 19, 2026, Hepatology Communications published the manuscript titled “Effect of tiomolibdate choline on copper balance in patients with Wilson disease: an open-label Phase 2 trial.” This peer-reviewed publication reported results from the Phase 2 ALXN1840-WD-204 study (NCT04573309) and demonstrated that ALXN1840 produced a rapid, statistically significant, and sustained improvement in daily copper balance in patients with Wilson disease, driven by increased fecal copper excretion. Susan Rodriguez, who joined as Chief Commercial and Strategy Officer in March 2026, is leading preparations for a potential commercial launch. Commercial readiness has been further strengthened by the appointment of Nicole Sweeny, former Chief Commercial Officer of KalVista Pharmaceuticals, to the Board of Directors and the additions of Sharon Funk as Senior Vice President of Sales and Marketing, and Daniel Olmstead as Senior Vice President of Market Access, Distribution and Patient Services. Financial Results for the Second Quarter Ended June 30, 2026, Compared to the Second Quarter Ended June 30, 2025 Cash and Net Loss Cash, cash equivalents and investments as of June 30, 2026, were $134.3 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 second quarter of 2026 was $5.3 million, or $0.62 per share, compared to net loss of $2.5 million, or $0.35 per share, for the second quarter of 2025. Research and Development (“R&amp;D”) Expenses R&amp;D expenses for the second quarter of 2026 were $4,766,832 compared to $1,730,000 for the second quarter of 2025. This represents an increase of $3,036,831 primarily attributed to (1) a $2,026,851 increase in R&amp;D contractor and consulting expenses, (2) a $721,228 increase in R&amp;D personnel expenses including stock-based compensation and (3) a net increase of $288,752 in other R&amp;D expenses. General and Administrative (“G&amp;A”) Expenses G&amp;A expenses for the second quarter of 2026 were $1,877,831 compared to $1,504,295 for the second quarter of 2025. This represents an increase of $373,536 primarily attributed to (1) a $234,113 increase in G&amp;A personnel expenses including stock-based compensation, (2) a $198,988 increase in G&amp;A contractor and consulting expenses and (3) a net decrease of $59,565 in other G&amp;A expenses. Other Income (Loss) Other income for the second quarter of 2026 was $32,158 compared to $0 for the second quarter of 2025. The increase is primarily attributable to an adjustment to a vendor invoice recognized during the current period. Interest Income (Loss) Interest income for the second quarter of 2026 was $1,299,205 compared to $780,769 for the second quarter of 2025. The increase is attributed to interest earned on U.S. Treasury securities and commercial paper and to higher bank balances in 2026 due to the net proceeds of approximately $91.9 million from the September 2025 capital raise. About Wilson Disease Wilson disease is a rare genetic disorder that affects approximately 1 in 30,000 people worldwide. It is caused by mutations in the ATP7B gene, which impairs the body’s ability to excrete copper. It is characterized by toxic accumulation of copper in the liver, brain, and other organs, leading to progressive and potentially fatal outcomes if untreated. About ALXN1840 ALXN1840 (tiomolibdate choline, TMC) is a novel first-in-class albumin tripartite complex (ATC) activator under investigation for the treatment of Wilson disease. ALXN1840 rapidly mobilizes and tightly sequesters excess copper in stable ATCs, suppressing copper’s redox reactivity, limiting oxidative damage, and blocking its transport across the blood–brain barrier. Clinical data have also demonstrated that ALXN1840 improves copper balance by increasing fecal copper excretion. In the pivotal Phase 3 trial, ALXN1840 met its primary endpoint, demonstrating rapid and sustained copper mobilization that was significantly greater than standard of care over 48 weeks in both previously treated and treatment-naïve patients. Across the ALXN1840 clinical development program, durable clinical improvement and favorable tolerability were observed across 645 patient-years of follow-up in 266 patients, with a well-characterized safety profile. About Monopar Therapeutics Inc. Monopar Therapeutics is a clinical-stage biopharmaceutical company with late-stage ALXN1840 for Wilson disease, and radiopharmaceutical programs including MNPR-101-Zr (Phase 1) for imaging advanced cancers along with MNPR-101-Lu (Phase 1a) and MNPR-101-Ac (late preclinical) for the treatment of advanced cancers.
