Current report

We are a clinical-stage biopharma company with late-stage ALXN1840 for Wilson disease, and radiopharmaceutical programs, including Phase 1-stage MNPR-101-Zr for imaging advanced cancers along with Phase 1a-stage MNPR-101-Lu and late preclinical-stage MNPR-101-Ac225 for the treatment of advanced cancers. We leverage our scientific and clinical experience to help reduce the risk and accelerate the clinical development of our drug product candidates.

Current report

On October 30, 2024, pursuant to a placement agent agreement with Rodman & Renshaw LLC, we sold 1,181,540 shares of our common stock at $16.25 per share in a public offering, yielding net proceeds of approximately $17.8 million, after deducting placement agent fees and other offering expenses.

Current report

On December 23, 2024, pursuant to an underwriting agreement with Piper Sandler & Co., we sold 798,655 shares of our common stock at $23.79 per share in a public offering. Concurrent with that offering, we completed a private placement of pre-funded warrants to purchase 882,761 shares of common stock at a purchase price of $23.789 per pre-funded warrant to an institutional investor. The net proceeds of the shares and the pre-funded warrants sold were approximately $37.4 million after fees, commissions and other offering expenses.

Current report

ALXN1840 (bis-choline tetrathiomolybdate) is an investigational once-daily, orally-administered drug candidate in development for the treatment of Wilson disease, a rare and progressive genetic condition in which the body’s pathway for removing excess copper is compromised. Over time this excess copper results in the build-up of toxic copper levels in the liver, brain, and other organs, leading to damage that greatly impacts a patient’s life. Patients can develop a wide range of symptoms, including liver disease and psychiatric or neurological manifestations, such as personality changes, tremors and difficulty walking, swallowing or talking. In some cases, the damage and loss of function may be irreversible. ALXN1840 is a novel small molecule designed to selectively and tightly bind and remove copper from the body’s tissues and blood. ALXN1840 has been granted Orphan Drug Designation and Fast Track designation in the U.S. and orphan designation in the EU.

Current report

Wilson disease affects 1 in 30,000 live births in the U.S. There are an estimated 10,000 Wilson disease patients in the U.S., with an estimated 5,000 patients currently diagnosed and being treated with SoC.

Current report

Alexion completed a pivotal Phase 3 clinical trial of Wilson disease patients on ALXN1840, which met its primary endpoint in assessing copper mobilization over 48 weeks, defined as daily mean Area Under the Effect Curve (“AUEC”) for directly measured non-ceruloplasmin-bound copper (“dNCC”). In the trial, 214 patients were enrolled, and the trial was randomized, rater-blinded, and multi-centered, designed to evaluate the efficacy and safety of ALXN1840 versus standard-of-care (“SoC”) in patients with Wilson disease aged 12 years and older. Patients taking ALXN1840 experienced rapid copper mobilization, with a response at 4 weeks and sustained through the 48 weeks. The primary endpoint demonstrated three-times greater copper mobilization with ALXN1840 compared to the SoC arm (Least Square Mean Difference (“LSM Diff”) 2.18 µmol/L; p< 0.0001), including in patients who had been treated previously with SoC for an average of 10 years.

Current report

Additionally, data from patients in the Phase 3 clinical trial who exhibited at the time of study entry an incomplete and/or intolerant response (“IIR”) to prior treatment on SoC showed that more patients on ALXN1840 as compared to SoC in the trial exhibited improved neurological symptoms (45% vs. 20%, respectively) and fewer exhibited worsened neurological symptoms (5% vs. 17%, respectively) when assessed on a reported Minimal Clinically Important Difference (“MCID”) scale. These data suggest ALXN1840 may reduce the risk of neurological worsening when compared to SoC.

Current report

Alexion terminated the ALXN1840 program in Wilson disease based on its review of results from Phase 2 mechanistic trials and discussions with regulatory authorities. Their analysis of the Phase 2 mechanistic trials was that they failed to demonstrate a net-negative copper balance in Wilson disease patients during short-term treatment with ALXN1840 and to reduce hepatic copper concentration after treatment with ALXN1840. The decision not to progress the ALXN1840 program in Wilson disease was not related to any safety signals.

Current report

Following Alexion’s decision, in October 2024, we entered into an exclusive worldwide license for the program and assumed responsibility for all future global development and commercialization activities. In the near term, we will be focusing on assembling a regulatory package and submitting an NDA. We expect to submit an NDA to the FDA in early 2026.

Current report

We have a proprietary first-in-class humanized monoclonal antibody, MNPR-101, that targets the urokinase plasminogen activator receptor (“uPAR”). uPAR is expressed on several of the more aggressive, deadly cancers including pancreatic, breast, ovarian, colorectal, and bladder cancers. We have conjugated MNPR-101 to imaging and therapeutic radioisotopes for the purpose of creating highly precise radiopharmaceutical agents that have the potential to image and treat tumors expressing uPAR while reducing exposure to healthy tissues. In February 2024, we received regulatory clearance in Australia to commence a first-in-human Phase 1 imaging and dosimetry clinical trial with our novel radiopharmaceutical imaging agent MNPR-101-Zr (MNPR-101 conjugated to zirconium-89) in patients with advanced cancers, and in April 2024, we launched the Phase 1 trial. In July 2024, we announced the enrollment of our first patient and in September 2024, we announced positive early clinical data validating the tumor-targeting ability of MNPR-101-Zr. In August 2024, we received regulatory clearance in Australia to commence a first-in-human Phase 1a clinical trial of our novel uPAR-targeted radiopharmaceutical therapy MNPR-101-Lu (MNPR-101 conjugated to lutetium-177) in patients with advanced solid cancers. We launched the trial in October 2024, and it is now active and open for patient enrollment. We dosed our first with MNPR-101-Lu in early December 2024.

Current report

In October 2024, we presented clinical data at the European Association of Nuclear Medicine Annual Congress 2024 showing significant uptake of MNPR-101-Zr in a patient with advanced ovarian cancer together with preclinical and clinical data showing favorable biodistribution, tumor uptake, and low off-target binding of our uPAR-targeted radiopharmaceuticals MNPR-101-Zr, MNPR-101-Lu, and MNPR-101-Ac (MNPR-101 conjugated to actinium-225).

Current report

We are also actively exploring opportunities to expand our radiopharmaceutical pipeline primarily through internal development efforts. In October 2024, we announced the filing of a provisional patent application for new radiopharmaceutical compounds and a family of linkers used to connect radioisotopes with targeting agents, including our uPAR-targeting antibody MNPR-101.

Current report

Other income for the year ended December 31, 2024, increased by $171,000 versus the year ended December 31, 2023, due to the release of an accrued liability.

Current report

Interest income for the year ended December 31, 2024, decreased by $25,000 versus the year ended December 31, 2023.

Current report

During the years ended December 31, 2024 and 2023, we had net cash inflow of $38,550,000 and net cash outflow of $920,000, respectively, an increase of $39,470,000. The increase in cash used in investing activities during the year ended December 31, 2024, compared to the year ended December 31, 2023, was due to the increase in funds available to invest from the October 2024 financing. The increase in net cash provided by financing activities during the year ended December 31, 2024, compared to the year ended December 31, 2023, was a result of higher proceeds from sales of our common stock under an at-the-market sales program and the October 2024 and December 2024 financing rounds.

Current report

On October 23, 2024, the Company executed a License Agreement with Alexion, pursuant to which Alexion granted us an exclusive worldwide license for the development and commercialization of ALXN1840, a drug candidate for Wilson disease. As initial upfront consideration for the License Agreement, we issued Alexion 387,329 shares (representing 9.9% of our outstanding shares at the time) of our common stock and agreed to make an upfront cash payment of $4.0 million. A cash payment of $1.0 million was paid at the time of signing and the remaining $3.0 million was paid in January 2025, pursuant to the terms of the agreement. We agreed to an anti-dilution provision that entitled Alexion to receive additional shares at no cost to maintain their 9.9% ownership until we raised the next $25.0 million of our common stock, subject to a maximum of 705,015 shares unless we obtained stockholder approval. Pursuant to the anti-dilution right, we issued an additional 157,188 shares of common stock to Alexion. No further obligations exist pursuant to the anti-dilution right.

Current report

Additionally, we are obligated to milestone payments of up to $94.0 million for the achievement of regulatory approval and sales related milestones. In addition, the Company is obligated to pay tiered royalties based on net sales in the low- to mid-double digit range. We have also given Alexion the right of first negotiation regarding any rights should we intend to sublicense ALXN1840. Furthermore, we will have to pay Alexion a percentage in the mid-double digits of any sublicensing income received by us. As part of this License Agreement, we have assumed an agreement from Alexion, under which we will also owe a third-party single digit millions in cash milestone payment upon regulatory approval in Europe and a single digit percentage royalty on net sales in Europe.

Current report

In June 2024, we entered into a long-term, non-exclusive master supply agreement with NorthStar under which NorthStar will provide us with the therapeutic radioisotope actinium-225 (“Ac-225”). The original collaboration agreement was amended at that time to clarify certain economic terms and terms related to jointly developed intellectual property rights for our MNPR-101 for radiopharmaceutical use. We have acquired these rights from NorthStar, together with certain broad, jointly developed intellectual property pertaining to MNPR-101, giving us full ownership and title to our lead MNPR-101 radiopharmaceutical platform. We will jointly share ownership of the filed patent application on the use of PCTA as a linker with Ac-225, which has shown that MNPR-101 has superior binding and yield with Ac-225 over the current industry-leading linker, DOTA.

Previous report

We are a clinical stage biopharmaceutical company focused on developing innovative treatments for cancer patients. We are building a drug development pipeline through the licensing and acquisition of therapeutics in late preclinical or in clinical development stages. We leverage our scientific and clinical experience to help reduce the risk of and accelerate the clinical development of our drug product candidates.

Previous report

From January 1 to March 8, 2024, we sold 2,545,305 shares of our common stock at an average gross price per share of $1.29 for net proceeds of $3,194,310, after fees and commissions of $81,932.

Previous report

Our proprietary, novel MNPR-101 radiopharmaceutical program is a first-in-class urokinase plasminogen activator receptor ("uPAR") targeting radiopharmaceutical for advanced tumors. The Company's radiopharmaceutical development team has conjugated MNPR-101, its proprietary first-in-class humanized monoclonal antibody that is highly selective against uPAR, to imaging and therapeutic radioisotopes, to develop highly precise imaging and therapeutic radiopharmaceutical agents that have the potential to image and eradicate tumors expressing uPAR while sparing healthy tissues. In February 2024, the Company announced promising preclinical data and regulatory clearance in Australia to commence a first-in-human Phase 1 clinical trial of MNPR-101-Zr for imaging tumors in patients with advanced cancers. Monopar is moving aggressively towards opening enrollment to patients in this Phase 1.

Previous report

The Phase 1b open-label, dose-escalating clinical trial of camsirubicin in patients with advanced soft tissue sarcoma (“ASTS”) is currently ongoing and enrolling in the fifth dose-level cohort (650 mg/m 2), which is nearly 2.5x the highest dose evaluated in any prior camsirubicin clinical trial (265 mg/m 2).

Previous report

MNPR-202, an analog of camsirubicin designed to potentially treat doxorubicin- and camsirubicin-resistant cancers, is being tested in preclinical models by our collaborator, the Cancer Science Institute of Singapore at the National University of Singapore.

Previous report

On March 27, 2023, we announced that based on Validive not meeting the pre-specified efficacy threshold in our interim clinical trial data analysis, we terminated the study, discontinued the development of Validive and subsequently terminated the license with Onxeo, SA.

Previous report

We qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (“JOBS Act”). An emerging growth company may take advantage of specified reduced reporting burdens that are otherwise applicable generally to public companies. These provisions include, but are not limited to:

Previous report

We expect to take advantage of these provisions until we are no longer an emerging growth company. We will remain an emerging growth company until the earliest of (1) the last day of the year (a) following the fifth anniversary of the completion of our initial public offering which is December 2024, (b) in which we have total annual gross revenue of at least $1.235 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30th, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. We expect to no longer qualify as an emerging growth company at the end of 2024.

Previous report

We have elected to take advantage of certain of the reduced disclosure obligations in this Annual Report on Form 10-K, and may elect to take advantage of other reduced reporting requirements in future filings. As a result, the information that we provide to our stockholders may be reduced and/or less detailed than what you might find from other public reporting companies.

Previous report

In addition, we are also a “smaller reporting company” as defined in Rule 12b-2 of the Exchange Act and have elected to take advantage of certain of the scaled back disclosure requirements available to smaller reporting companies such as avoiding the extensive narrative disclosure required of other reporting companies, particularly in the description of executive compensation. Our status as a smaller reporting company will not be impacted by the loss of emerging growth company status at the end of 2024, so we may continue to take advantage of these scaled disclosure requirements so long as we qualify. In addition, the loss of emerging growth status will not impact our “non-accelerated filer” status, which also provides an exemption from the auditor attestation requirement with respect to internal control over financial reporting.

Previous report

Interest income for the year ended December 31, 2023, increased by $408,000 versus the year ended December 31, 2022. The increaseis due to interest earned on treasury bills and money market accounts that yielded higher interest ratesin 2023.

Expenditures are expected to increase in 2024 and onward for:

Previous report

In June 2016, we executed an agreement with Onxeo S.A., a French public company, which gave us the exclusive option to license (on a world-wide exclusive basis) Validive (clonidine hydrocholoride mucobuccal tablet; clonidine HCI MBT) a mucoadhesive tablet of clonidine based on the Lauriad mucoadhesive technology. In September 2017, we exercised the option to license Validive from Onxeo for $1 million. In March 2023, we discontinued our Validive Phase 2b/3 VOICE trial based upon ours Data Safety Monitoring Board’s determination that the trial did not meet the pre-defined threshold for efficacy of a 15% absolute difference in severe oral mucositis prevention between Validive and placebo. We have not incurred any license or royalty obligations and the license has been terminated effective January 2024.

Previous wording

We account for stock-based compensation arrangements with employees, non-employee directors and consultants using a fair value method, which requires the recognition of compensation expense for costs related to all stock-based compensation grants, including stock option and restricted stock unit (“RSU”) grants. The fair value method requires us to estimate the fair value of stock-based payment awards on the date of grant using an option pricing model or the closing stock price on the date of grant in the case of RSUs.

Current wording

We account for stock-based compensation arrangements with employees, non-employee directors and consultants using a fair value method, which requires the recognition of compensation expense for costs related to all stock-based compensation grants, including stock option and restricted stock unit (“RSU”) grants. The fair value method requires us to estimate the fair value of stock-based payment awards on the date of grant using an option pricing model or, in the case of RSUs, the closing stock price on the date of grant.

Previous wording

Stock-based compensation costs for stock awards granted to our employees, non-employee directors and consultants are based on the fair value of the underlying instruments calculated using the Black-Scholes option-pricing model on the date of grant for stock options and using the closing stock price on the date of grant for RSUs and recognized as expense on a straight-line basis over the requisite service period, which is the vesting period. Determining the appropriate fair value model and related assumptions requires judgment, including selecting methods for estimating our future stock price volatility and expected holding term. For options granted in 2023, the expected volatility rates are estimated based on our actual historical volatility over the three-year period from our initial public offering on December 18, 2019, through December 31, 2022. The expected term for stock options granted during the years ended December 31, 2023 and 2022, was estimated using the simplified method. Forfeitures only include actual forfeitures to-date as the Company accounts for forfeitures as they occur due to a limited history of forfeitures. We have not paid dividends and do not anticipate paying a cash dividend in future vesting periods and, accordingly, use an expected dividend yield of zero. The risk-free interest rate is based on the rate of U.S. Treasury securities with maturities consistent with the estimated expected term of the awards.

R&D expenses for the year ended December 31, 2024, were $13,006,000, compared to $5,600,000 for the year ended December 31, 2023. This represents an increase of $7,406,000 primarily attributed to (1) a $8,557,000 increase related to the in-licensing of ALXN1840, (2) a $335,000 increase in R&D personnel expenses and (3) a $130,000 net increase in other R&D expenses, partially offset by (4) a $1,616,000 decrease in Validive clinical trial-related expenses due to the closure of the trial in March 2023.

Previous wording

G&A expenses for the year ended December 31, 2023, were $3,231,000, compared to $2,945,000 for the year ended December 31, 2022. This represents an increase of $286,000 primarily attributed to a $220,000 increase in G&A personnel salaries, bonuses, benefits and stock-based compensation for annual (non-cash) equity grants, and a $66,000 net increase in other G&A expenses.

Current wording

G&A expenses for the year ended December 31, 2024, were $3,156,000, compared to $3,231,000 for the year ended December 31, 2023. This represents a decrease of $75,000 primarily attributed to a decrease in G&A personnel expensesdue to the reduction in equity grants to our Chief Executive Officer in 2024.

Previous wording

We have incurred losses and cumulative negative cash flows from operations since we commenced operations resulting in an accumulated deficit of approximately $60.2 million as of December 31, 2023. We anticipate that we will continue to incur losses for the foreseeable future. We expect that our R&D and G&A expenses will increase to enable the execution of our strategic plan. As a result, we anticipate that we will seek to raise additional capital within the next 12 months to fund our future operations. We will seek to obtain needed capital through a combination of equity offerings, including at-the-market sales programs, debt financings, strategic collaborations and grant funding. To date, we have funded our operations through net proceeds from the initial public offering of our common stock, net proceeds from sales of our common stock through at-the-market sales programs, private placements of our preferred and common stock, and the net receipt of funds related to the acquisition of camsirubicin. We anticipate that the currently available funds as of March 8, 2024, will fund our planned operations at least through June 30, 2025.

Current wording

We have incurred losses and cumulative negative cash flows from operations since we commenced operations, resulting in an accumulated deficit of approximately $75.8 million as of December 31, 2024. We anticipate that we will continue to incur losses for the foreseeable future. We expect that our R&D and G&A expenses will increase to enable the execution of our strategic plan. We anticipate that the currently available funds as of March 14, 2025, will fund our planned operations at least through December 31, 2026. We will seek to obtain needed capital through a variety of methods, including but not limited to the sale of our common stock, debt financings, strategic partnerships or other sources of capital at our disposal.

Previous wording

We invest our cash equivalents in two money market accounts and U.S. Treasury Bills.

Current wording

We invest our cash equivalents in money market accounts and U.S. Treasury securities.

Previous wording

The cash flow used in operating activities during the year ended December 31, 2023, compared to the year ended December 31, 2022 was essentially flat.

Current wording

The decrease of $1,454,000 in cash flow used in operating activities during the year ended December 31, 2024, compared to the year ended December 31, 2023, was primarily related to an increase in liabilities including the accrual of $3,000,000 related to the upfront payment payable to Alexion for the in-licensing of ALXN1840.

Previous wording

During the years ended December 31, 2023 and 2022, we had net cash outflows of $920,000 and $12,118,000, respectively, a decrease of $11,198,000. During 2022, we began investing our idle cash due to the rising interest rates, resulting in a significant increase in cash used in investing activities. During 2023, we had net cash provided by investing activities as some of our investments made in 2022 matured and were used in operating activities, as well as higher net cash provided by financing activities due to more funds raised from sales of our common stock under an at-the-market sales program comparedto 2022.

Previous wording

The increase to cash flow provided by investing activities during the year ended December 31, 2023, compared to cash used in investing activities during the year ended December 31, 2022, of $9,847,000 was related to the fact that our investment in U.S. Treasury Bills commenced in December 2022 with maturities reinvested or used as working capital throughout 2023.

Current wording

The increase to cash flow used in investing activities during the year ended December 31, 2024, compared to cash provided by investing activities during the year ended December 31, 2023, of $19,266,000 was related to the purchase of investments in U.S. Treasury securities during 2024 resulting from an increase in cash available for investment from proceeds from sales of our common stock under an at-the-market sales program and from the October 2024 financing.

Previous wording

The increase in cash flow provided by financing activities during the year ended December 31, 2023, compared to the year ended December 31, 2022, of $1,994,000 was primarily due to higher net proceeds from sales of our common stock through an at-the-market sales program.

Current wording

The increase in cash flow provided by financing activities during the year ended December 31, 2024, compared to the year ended December 31, 2023, of $57,265,000 was primarily due to higher net proceeds from sales of our common stock through an at-the-market sales program and the October 2024 and December 2024 financing rounds.

Previous wording

To date, we have not generated any revenue from product sales. We do not know when, or if, we will generate any revenue from product sales. We do not expect to generate any revenue from product sales or royalties unless and until we obtain regulatory approval of and commercialize any of our current or future drug product candidates or we out-license or sell a drug product candidate to another party. At the same time, we expect our expenses to increase in connection with our ongoing development activities, particularly as we continue the research, development, future preclinical studies and clinical trials of, and seek regulatory approval for, our current and future drug product candidates. If we obtain regulatory approval of any of our current or future drug product candidates, we will need substantial additional funding for commercialization requirements and our continuing drug product development operations.

Previous wording

We are working towards initiating enrollment for our MNPR-101-Zr Phase 1 dosimetry clinical trial. If the tumor uptake, biodistribution, and safety look encouraging in this Phase 1 dosimetry trial, we may proceed to evaluate the efficacy in humans of a therapeutically radio-labeled version of MNPR-101 bound to an isotope such as Ac-225, which will require additional funding or finding a suitable pharmaceutical partner. There can be no assurance that any such events will occur. We intend to continue evaluating drug product candidates for the purpose of growing our pipeline. Identifying and securing high-quality compounds usually takes time and related expenses; however, our spending could be significantly accelerated in 2024 and onward if additional drug product candidates are acquired and enter clinical development. In this event, we may be required to expand our management team, and pay higher contract manufacturing costs, contract research organization fees, other clinical development costs and insurance costs that are not currently projected. Additional long-term funding is needed to generally to support our current and future product candidates through clinical trials, approval processes and, if applicable, commercialization.

Beyond our current funds, substantial additional long-term funding is needed to further develop our radiopharmaceutical and rare disease programs.

Previous wording

Until we can generate a sufficient amount of product revenue to finance our cash requirements, we expect to finance our future cash needs primarily through a combination of equity offerings, including at-the-market sales programs, debt financings, strategic collaborations and grant funding. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our current stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect our current stockholders’ rights. Debt financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise additional funds through marketing and distribution arrangements or other collaborations, strategic alliances or licensing arrangements with other parties, we likely will have to share or relinquish valuable rights to our technologies, future revenue streams, research programs or drug product candidates or grant licenses on terms that may not be favorable to us, which will reduce our future returns and affect our future operating flexibility. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our pipeline product development or commercialization efforts or grant rights to others to develop and market drug product candidates that we would otherwise prefer to develop and market ourselves.

Previous wording

Pursuant to a non-exclusive license agreement with XOMA Ltd. for the humanization technology used in the development of MNPR-101, we are obligated to pay XOMA Ltd. clinical, regulatory and sales milestones which could reach up to $14.925 million if we achieve all milestones for MNPR-101. The agreement does not require the payment of sales royalties. There can be no assurance that we will achieve any milestones. As of March 8, 2024, we had not reached any milestones and had not been required to pay XOMA Ltd. any funds under this license agreement. The first milestone payment is payable upon first dosing of a human patient in a Phase 2 clinical trial.

Current wording

To humanize our MNPR-101 antibody, we have taken a non-exclusive license to XOMA (US) LLC’s humanization technology and know-how. Humanization involves replacing most of the non-critical parts of the mouse sequence of an antibody with the human sequence to minimize the ability of the human immune system to recognize this antibody as foreign. As such, MNPR-101 has been engineered to be 95% human sequence using the XOMA technology. Under the terms of the non-exclusive license with XOMA Ltd., we are to pay only upon the achievement of clinical, regulatory and sales milestones, potentially totaling $14.925 million. The agreement does not require the payment of sales royalties. As of March 14, 2025, we had not reached any milestones and had not been required to pay XOMA Ltd. any funds under this license agreement. The first milestone payment is payable upon first dosing of a human patient in a Phase 2 clinical trial. We are currently conducting Phase 1 clinical trials and cannot reliably predict when we will be able to commence a Phase 2 clinical trial, if at all.

Previous wording
