– Phase 1B portion of Phase 1B/2 study demonstrated preliminary CR/CRi rate of
– Annamycin has Fast Track Status and Orphan Drug Designation from FDA for the treatment of AML
Walter Klemp, Chairman and Chief Executive Officer of Moleculin commented, "This milestone marks an important step in advancing the development of Annamycin for the treatment of AML. Based on the positive preliminary results demonstrated in the Phase 1B portion of this trial, we continue to believe that Annamycin has the potential to be a meaningful treatment option for the treatment of AML. Our team is dedicated to building on the momentum and encouraging results to bring this study across the finish line and towards late-stage development."

As previously announced, Moleculin successfully and safely completed the Phase 1B portion of the trial at 230 mg/m2 of Annamycin in this combination study in August 2023.

Annamycin is the Company's next-generation anthracycline that has been designed to be non-cardiotoxic 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 relapsed or refractory AML and soft tissue sarcoma (STS) lung metastases and the Company believes it may have the potential to treat additional indications.
Annamycin currently has Fast Track Status and Orphan Drug Designation from the US Food and Drug Administration (FDA) for the treatment of STS lung metastases and the treatment of relapsed or refractory AML.
