Liposomal muramyl tripeptide phosphatidyl ethanolamine (L-MTP-PE) is a synthetic biological investigational agent used for treating osteosarcoma. It has been used in both canine and human osteosarcoma to reduce pulmonary metastases, the most common pattern of treatment failure for sarcomas. L-MTP-PE
Osteosarcoma is the most common form of primary malignant bone tumor. The use of chemotherapy drugs with many side effects, including high-dose methotrexate, doxorubicin, cisplatin and ifosfamide, has greatly improved osteosarcoma survival compared with surgery alone. However, for 20 years, overall
The macrophage activator muramyl tripeptide-phosphatidyl ethanolamine (MTP-PE) was infused in liposomal form in 14 metastatic cancer patients (4 mg i.v. during 30 min twice weekly for 12 weeks). Clinical, pharmacokinetic and immunological parameters were studied before and 0.5, 2, 4, 24 and 72h
Mifamurtide, also known as liposomal muramyl tripeptide phosphatidyl ethanolamine (L-MTP-PE), has been approved for the treatment of osteosarcoma in Europe. Mifamurtide's rational drug design employs MTP-PE for macrophage activation in a multilamellar liposome drug carrier, containing the synthetic
OBJECTIVE
This study evaluated the pharmacokinetics (PK), pharmacodynamics (PD), safety/tolerability, and cardiac safety of liposomal muramyl tripeptide phosphatidyl-ethanolamine [mifamurtide (L-MTP-PE)] in healthy adults.
METHODS
L-MTP-PE 4 mg was administered intravenously over 30 min. Study
Mifamurtide (liposomal muramyl tripeptide phosphatidyl ethanolamine; Mepact) is an immunomodulator with antitumor effects that appear to be mediated via activation of monocytes and macrophages. In the EU, mifamurtide is indicated in children, adolescents, and young adults for the treatment of
