Monopar Therapeutics Reports Fourth Quarter and Full-Year 2021 Financial Results and Recent Program Developments

Validive^® Phase 2b/3 VOICE Trial Continues Adding Sites in the U.S. and Europe

Camsirubicin Phase 1b Dose-Esclation Trial Clears 2nd Dose Level and is Now Enrolling 3rd Dose-Level Cohort

WILMETTE, Ill., March 24, 2022 (GLOBE NEWSWIRE) -- Monopar Therapeutics Inc. (Monopar or the Company) (Nasdaq: MNPR), a clinical-stage biopharmaceutical company focused on developing proprietary therapeutics designed to extend life or improve the quality of life for cancer patients, today announced fourth quarter and full-year 2021 financial results and summarized recent program developments.

Recent Program Developments and Highlights

Validive – International Phase 2b/3 VOICE Clinical Trial, Actively Recruiting

• Validive is a novel mucobuccal tablet formulation for clonidine that has been designed to provide for prolonged and enhanced local delivery of clonidine to the regions of oral mucosal radiation damage in patients being treated for oropharyngeal cancer.
• Monopar received clearance in the U.S. and multiple European countries to conduct its Phase 2b/3 VOICE clinical trial of Validive (clonidine HCl mucobuccal tablet) (NCT04648020 / EudraCT No. 2021-000999-11) for the prevention of severe oral mucositis (SOM) in patients undergoing chemoradiotherapy (CRT) for oropharyngeal cancer.
• The VOICE trial now has 44 active clinical trial sites in the U.S. and Europe, continues to open additional sites globally, and is on track to reach the interim analysis in mid-2022. Based on findings extracted from public reporting of recently completed SOM trials, Monopar is presently evaluating potential enhancements to and exact timing of the interim analysis.
• There is no FDA-approved prevention or treatment for CRT-induced SOM.

Camsirubicin – Phase 1b Dose-Escalation Trial, Actively Recruiting

• Camsirubicin, a propriety doxorubicin analog, has been engineered specifically to retain the anticancer activity of doxorubicin while minimizing the toxic effects on the heart.
• In August 2021, Monopar received clearance from the U.S. Food and Drug Administration to proceed under an Investigational New Drug (IND) application with an open-label Phase 1b dose-escalation clinical trial evaluating camsirubicin plus growth factor support (pegfilgrastim/G-CSF) in patients with advanced soft tissue sarcoma (ASTS) (NCT 05043649).
• First patient was dosed in October 2021.
• Monopar is currently enrolling the third dose-level, which is a higher dose level of camsirubicin than tested in any previous clinical trial.
• Early signs of clinical benefit have been observed with camsirubicin in this Phase 1b trial.

MNPR-101 and Related Compounds

• MNPR-101 is a preclinical stage uPAR-targeted antibody being developed as a radioimmunotherapeutic and companion diagnostic for advanced cancers and severe COVID-19.
• In collaboration with NorthStar Medical Radioisotopes, Monopar filed a provisional patent describing antibody conjugates of the metal binding agent PCTA, based on the unexpected observation of nearly 100% binding of Ac-225 to the PCTA-antibody conjugates.
• A provisional patent was also filed covering a radiotherapeutic consisting of Monopar’s proprietary antibody MNPR-101 bound to Actinium-225 (Ac-225) via the metal binding agent PCTA (MNPR-101-PCTA-Ac-225).
• Currently evaluating pathways to initiating a first-in-human study.

MNPR-202

• MNPR-202 is a novel analog of camsirubicin, modified to potentially enable it to evade doxorubicin drug resistance mechanisms.
• Monopar entered into a collaboration and commenced work with Cancer Science Institute of Singapore to evaluate activity of MNPR-202 in preclinical models of multiple cancers.
• Composition of matter patent covering MNPR-202 has been allowed in the U.S.

Results for the Fourth Quarter and Year Ended December 31, 2021, Compared to the Fourth Quarter and Year Ended December 31, 2020

Cash and Net Loss

Cash and cash equivalents as of December 31, 2021, were $20.3 million. Monopar anticipates that its current cash and cash equivalents will fund: the Phase 2b portion of the VOICE clinical trial; the commencement of the Phase 3 portion of the VOICE clinical trial; and the Phase 1b camsirubicin clinical trial through at least March 2023. The Company plans to raise additional funds and/or engage a partner within the next 12 months to complete the VOICE clinical program and continue camsirubicin clinical development through and beyond the ongoing open-label, dose escalation Phase 1b clinical trial.

Net loss for the fourth quarter of 2021 was $2.7 million or $0.21 per share compared to net loss of $2.1 million or $0.19 per share for the fourth quarter of 2020. Net loss for the year ended December 31, 2021 was $9.1 million or $0.73 per share compared to net loss of $6.3 million or $0.58 per share for the year ended December 31, 2020.

Research and Development (R&D) Expenses

R&D expenses for the fourth quarter of 2021 were $2.0 million compared to $1.6 million for the fourth quarter of 2020. This increase of $0.4 million was primarily due to increases of $0.5 million for R&D personnel expenses and $0.4 million for VOICE clinical trial expenses offset by a decrease of $0.5 million for Phase 1b camsirubicin clinical material manufacturing and other clinical trial planning expenses.

R&D expenses for the year ended December 31, 2021 were $6.5 million compared to $4.1 million for the year ended December 31, 2020. This increase of $2.4 million was primarily due to increases in expenses of $1.4 million for VOICE clinical trial expenses and $1.2 million for R&D personnel expenses offset by a decrease of $0.2 million for Phase 1b camsirubicin clinical material manufacturing expenses.

General and Administrative (G&A) Expenses

G&A expenses for the fourth quarter of 2021 were $0.7 million, compared to $0.6 million for the fourth quarter of 2020. This increase of $0.1 million was primarily due to an increase in G&A personnel expenses.

G&A expenses for the year ended December 31, 2021 were $2.6 million, compared to $2.4 million for the year ended December 31, 2020. This increase of $0.2 million was primarily due to an increase in G&A personnel expenses.
