Annamycin is under clinical development by Moleculin Biotech and currently in Phase II for Liposarcoma. According to GlobalData, Phase II drugs for Liposarcoma have a 35% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how Annamycin’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.

GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.

Annamycin overview

L-Annamycin is under development for the treatment of relapsed or refractory acute myelogeneous leukemia (AML), metastatic lung cancer, metastatic melanoma, soft-tissue sarcomas with pulmonary metastases, metastatic lung sarcoma, reticulosarcoma, metastatic pancreatic cancer (liver mets/pancreatic),  liposarcoma, leiomyosarcoma, synovial sarcoma, angiosarcoma, undifferentiated pleomorphic sarcoma, myxofibrosarcoma, malignant peripheral nerve sheath tumour, malignant solitary fibrous tumour, and pleomorphic RMS and metastatic osteosarcoma. The drug candidate is administered intravenously. L-Annamycin is a liposome nanoparticle formulation of annamycin, a second generation anthracycline. It is a liposome-encapsulated form of the semi-synthetic doxorubicin analogue annamycin with antineoplastic activity. It acts by targeting DNA topoisomerase II. It was under development for the treatment of relapsed and refractory acute lymphocytic leukemia (ALL).

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

GlobalData’s Likelihood of Approval analytics tool dynamically assesses and predicts how likely a drug will move to the next stage in its clinical pathway (PTSR), as well as how likely the drug will be approved (LoA). This is based on a proprietary algorithm built from the drugs’ sales forecast, regulatory milestones, cost forecasts, WACC rate and other proprietary data sources found on GlobalData’s Pharmaceutical Intelligence Center.
