Moleculin Announces New Positive Independent Report of No Cardiotoxicity in Annamycin
– Annamycin continues to demonstrate no evidence of cardiotoxicity to date, now in a total of 62 subjects across three of the Company's Annamycin clinical trials
– Next generation anthracycline, Annamycin, has demonstrated both safety and promising early activity across multiple clinical studies with potential to be an effective treatment across multiple oncology indications
HOUSTON, Sept. 18, 2023 /PRNewswire/ -- Moleculin Biotech, Inc., (Nasdaq: MBRX) ("Moleculin" or the "Company"), a clinical stage pharmaceutical company with a growing pipeline, including Phase 2 clinical programs, for hard-to-treat tumors and viruses, today announced it has received a new independent assessment for the absence of cardiotoxicity in subjects treated with Annamycin. Data from the following subjects were made available to an expert in chemotherapy who is affiliated with a leading cancer research institute in assessing cardiotoxicity. After review of this data, the independent expert concluded that there was no evidence of cardiotoxicity:
The data made available included left ventricular ejection fraction (LVEF) as determined by echocardiograms, ECHO strain imaging, and Troponin levels. "ECHO strain imaging" is a method in echocardiography (medical ultrasound) for measuring regional or global deformation (contraction or beating) of the myocardium (heart muscle). By strain rate imaging, the simultaneous function of different regions can be displayed and measured. Cardiac health biomarkers such as blood Troponin levels are considered an indicator of potential long-term heart damage.
"We continue to be encouraged by the potential of Annamycin, especially with the reports from this expert covering 62 subjects. This additional independent report of additional datasets provides further validation in the absence of cardiotoxicity," commented Walter Klemp, Chairman and Chief Executive Officer of Moleculin. "Annamycin continues to establish itself as a non-cardiotoxic anthracycline, even in subjects who have received far more than the lifetime maximum cumulative anthracycline exposure established by the FDA. In fact, 53 of the 62 subjects evaluated have been taken over the lifetime maximum of 450 mg/m2 and one of them as high as 3420 mg/m2. Our growing body of positive data for Annamycin continues to bolster our confidence in our belief that Annamycin is truly a 'next generation' anthracycline, especially in light of the growing efficacy data that we have previously reported in the treatment of STS lung mets and AML. We remain focused on advancing our Annamycin development programs and ultimately, addressing the medical unmet needs of people with difficult to treat cancers and viruses."
Annamycin is the Company's next-generation anthracycline that has been designed to be non-cardiotoxic (unlike currently prescribed anthracyclines) and has been shown in animal models to accumulate in the lungs at up to 30-fold the level of doxorubicin (a commonly prescribed anthracycline), as well as demonstrating the ability to avoid the multidrug resistance mechanisms that typically limit the efficacy of doxorubicin and other currently prescribed anthracyclines. Annamycin is currently in development for the treatment of STS lung metastases (STS lung mets) as well as both first line therapy and therapy for relapsed or refractory acute myeloid leukemia (AML), and the Company believes the drug may have the potential to treat additional indications.
