[{"type":"text","content":"HOUSTON, Oct. 29, 2019 /PRNewswire/ -- Moleculin Biotech, Inc., (Nasdaq: MBRX) (\"Moleculin\" or the \"Company\"), a clinical stage pharmaceutical company with a broad portfolio of drug candidates targeting highly resistant tumors, announced the presentation of a poster at the AACR-NCI-EORTC Molecular Targets and Cancer Therapeutics Conference today in Boston, MA. The poster, entitled \"Dose and Schedule-Dependent Efficacy of Liposomal Annamycin in Pre-clinical Models of Acute Myeloid Leukemia,\" presents data documenting the high activity of Annamycin against AML, including in vitro studies in a panel of human AML cell lines, as well as in vivo studies in both human and murine AML models developed under the Company's sponsored research agreement with MD Anderson Cancer Center.\n\n \n\"This study highlights an important new finding,\" commented Walter Klemp, Moleculin's Chairman and CEO. \"We've known for some time that Annamycin is effective in AML animal models and the activity that we believe is coming from our current AML clinical trials seems to correlate with this. But, what's new here is the observation that Annamycin may also be more effective than other drugs due to its high uptake and effectiveness in eliminating AML cells localized in different organs. Additional important observations made with these studies indicates that the long-term exposure of healthy mice (at least 12 doses so far) to a highly efficacious dose of 4 mg/kg administered weekly is not toxic and that even two weekly doses of 4 mg/kg are producing a significant increase in survival. And, because Annamycin is designed to be non-cardiotoxic, this extended dosing regimen may prove to be feasible and beneficial in humans. This potentially opens the door for expanded and improved dosing regimens in future clinical trials.\"\nQuoting from the accepted abstract: \"In vivo studies confirmed anti-tumor efficacy of Annamycin in both human and murine AML models. Based on bioluminescence imaging, the liposomal formulation of the drug significantly delayed AML progression in the human OCL-AML3/NSG model at 4 mg/kg with once weekly dosing. Similarly, significant dose-dependent reduction of peripheral blood AML blasts was observed in the murine AML-Turq2 model, and this reduction was strongly correlated with prolongation of animal survival. The median survival of m...
