No insider purchase over the last 90 days. The latest was filed 29 Dec 2025.
Headquartered in United States, Monopar Therapeutics belongs to the Healthcare & Pharma sector. Filings by its managers are published through SEC (Form 4). In the past year (18 October 2025 to 18 October 2026), 50 filings came from 15 insiders.
The record shows 1 purchase on the open market worth €89k, made by 1 insider, against 19 sales worth €3.8M by 6 insiders. The net balance comes to €3.8M on the selling side. A purchase on the market is a deliberate choice to commit personal money, which is why it draws more attention than a grant. Among those who bought: 1 finance chief. Biggest ticket of the year: €800k, sold by Robinson Chandler and made public on 28 September 2026 (0.16% of market cap).
Across the 5,458 companies tracked on its exchange, the median is 22 filings; at 50 filings, this issuer sits above that mark. Looking back to 2021, when coverage begins, insiders filed 7 purchases and 21 sales. In its latest annual report filed with the SEC (10-K, fiscal year ended 31 December 2025), the company reported net income of -13.7 m USD.
The most recent open-market purchase was published on 29 December 2025, 293 days ago. Typically, a trade is published a median of 2 days after it takes place. Section 16 rules allow two business days to file each Form 4. A sale on its own says little: insiders also sell to pay tax, fund a purchase or diversify.

Monopar Therapeutics Inc. is a clinical-stage biotechnology company listed on the Nasdaq in the United States under the ticker MNPR. For French-, Belgian- and Swiss-based investors, it should be viewed as a healthcare micro/small-cap whose investment profile is driven primarily by clinical and regulatory catalysts rather than current commercial revenues. The company was formed in December 2014 as a Delaware limited liability company and later established its executive headquarters in Wilmette, Illinois, with its team largely based in the Chicago area in the United States.

Monopar’s business is currently organized around two core development pillars. First, it is advancing ALXN1840, a late-stage therapy candidate for Wilson disease, a rare inherited disorder of copper metabolism. Second, it is building a radiopharmaceutical platform for oncology, including MNPR-101-Zr for imaging advanced solid tumors, MNPR-101-Lu for treatment, and MNPR-101-Ac in late preclinical development. This positioning places Monopar at the intersection of rare disease and precision oncology, two attractive but execution-heavy segments that require disciplined capital allocation, strong clinical data, and effective regulatory engagement.

From a competitive standpoint, Monopar remains a precommercial developer, so its market value depends largely on the strength of its clinical readouts, the timing of regulatory milestones, and its ability to differentiate itself against much larger pharmaceutical peers. In Wilson disease, the key question is whether ALXN1840 can deliver a compelling combination of efficacy, safety, and patient convenience that resonates with physicians, regulators, and ultimately payers. In radiopharmaceuticals, Monopar operates in a fast-moving but highly competitive category where tumor targeting, translational credibility, and manufacturing scalability matter greatly. The company describes its pipeline strategy as a mix of internal development and in-licensing of late-preclinical and clinical-stage assets, an approach intended to reduce early-stage risk and accelerate execution.

Recent developments are particularly important. In 2024, Monopar announced an exclusive worldwide license agreement with Alexion, AstraZeneca Rare Disease for ALXN-1840, a compound that had already advanced through Phase 3. In 2026, management said the company remained on track to submit a New Drug Application to the FDA in mid-2026 and highlighted the appointment of Susan Rodriguez as Chief Commercial and Strategy Officer to prepare for a possible launch. In its first-quarter 2026 results, Monopar reported cash, cash equivalents and investments of $137.5 million as of March 31, 2026, and stated that current funds are expected to support operations through at least December 31, 2027. The company’s ongoing SEC Form 4 filings also keep insider activity in focus for investors watching ownership changes and management alignment.
