New antineoplastic for treatment of osteosarcoma

Takeda has launched Mepact (mifamurtide) for the treatment of high-grade resectable non-metastatic osteosarcoma after macroscopically complete surgical resection, in children, adolescents and young adults, in combination with multi-agent chemotherapy.

Mifamurtide is a potent activator of monocytes and macrophages; however, the exact mechanism by which it exerts its anti-tumour effects is not yet known.

In a Phase III study involving 678 patients aged 1.4 to 30.6 years with newly diagnosed resectable high-grade osteosarcoma, the addition of Mepact to chemotherapy (doxorubicin, cisplatin and methotrexate, with or without ifosfamide) resulted in a 28 per cent relative reduction in risk of death (p=0.0313).
