Moleculin Announces 100% Survival Achieved In Osteosarcoma Lung Metastases Animal Model

HOUSTON, Feb. 2, 2021 /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 and viruses, today announced that a preclinical study in animals demonstrated a potentially significant therapeutic benefit of Annamycin against metastatic osteosarcoma. This appears to be the result of the high cytotoxic potential of Annamycin previously demonstrated in vitro against sarcoma cells in combination with its high uptake by the lungs where the tumors in this study are localized. Computerized tomography (CT) scans demonstrated that animals treated with Annamycin exhibited significant suppression of tumor growth and not a single death was observed in the treated animals, whereas significant tumor burden contributed to the rapid death of 90% of untreated animals. While the study continues, as of day 130, the survival rate for animals treated with Annamycin was 100%, compared with only 10% for untreated animals.
