WILMETTE, Ill., June 01, 2023 (GLOBE NEWSWIRE) -- Monopar Therapeutics Inc. (Nasdaq: MNPR), a clinical-stage biopharmaceutical company focused on developing innovative treatments for cancer, today announced an update from its currently enrolling multi-center open-label Phase 1b clinical trial of camsirubicin in patients with advanced soft tissue sarcoma (ASTS).
Background on ASTS and Camsirubicin
ASTS is a diverse type of cancer that typically develops in the connective tissue of the body and which has metastasized (spread) or is not amenable to surgery. The average life expectancy from time of diagnosis for patients with ASTS is about 12 to 15 months. Currently, doxorubicin is the first-line standard of care treatment for most types of ASTS.
Doxorubicin is one of the most widely used cancer drugs worldwide with FDA approval in ASTS and 13 additional cancer indications. Unfortunately, although higher doses of doxorubicin are known to be more effective at treating cancer, the risk of irreversible heart damage increases with the cumulative dose and limits the lifetime amount that a patient can receive. As a result, even if patients are responding, they discontinue doxorubicin treatment typically after only 6 to 8 cycles (~6 months or less).
Camsirubicin has been designed to retain the anti-cancer activity while avoiding the irreversible heart damage that is seen with doxorubicin. The hypothesis for camsirubicin is straightforward: modifying doxorubicin in order to reduce cardiac damage could enable higher and longer dosing, resulting in better efficacy and patient outcomes.
Updates from Currently Enrolling Phase 1b Clinical Trial
Camsirubicin Clinical Trial Design and GEIS Collaboration
The purpose of this 3+3 dose escalation Phase 1b trial is to determine the maximum tolerated dose (MTD) of camsirubicin. Once the MTD is reached, Monopar has a clinical collaboration agreement in place with the Spanish Sarcoma Group (Grupo Español de Investigación en Sarcomas, or GEIS) to conduct a multi-country randomized Phase 2 clinical trial. The Phase 2 plan is to evaluate camsirubicin head-to-head against doxorubicin in patients with ASTS, with GEIS as the study sponsor with support from Monopar.
Further information about this actively enrolling, open-label, dose-escalation Phase 1b clinical trial is available at www.ClinicalTrials.gov under study identifier NCT 05043649.

Forward-Looking Statements
Statements contained in this press release regarding matters that are not historical facts are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995.

Examples of these forward-looking statements include statements concerning: that modifying doxorubicin to create camsirubicin in order to reduce cardiac damage could enable higher and longer dosing, resulting in better efficacy and patient outcomes; and plans to conduct a multi-country randomized Phase 2 clinical trial once the MTD is reached evaluating camsirubicin head-to-head against doxorubicin in patients with ASTS, with GEIS as the study sponsor with support from Monopar. The forward-looking statements involve risks and uncertainties including, but not limited to: the camsirubicin Phase 1b trial not proving safety and efficacy at higher doses; not successfully recruiting additional patients and initiating additional clinical trial sites for the camsirubicin Phase 1b clinical trial within expected timeframes, if at all; the Company’s inability to raise sufficient funds or engage a partner to continue the camsirubicin clinical program beyond the Phase 1b clinical trial; GEIS not conducting the camsirubicin Phase 2 clinical trial; and the significant general risks and uncertainties surrounding the research, development, regulatory approval, and commercialization of therapeutics. Actual results may differ materially from those expressed or implied by such forward-looking statements. Risks are described more fully in Monopar's filings with the Securities and Exchange Commission. All forward-looking statements contained in this press release speak only as of the date on which they were made.
