摘要

Mifamurtide is a conjugate of muramyl tripeptide linked to dipalmitoyl phosphatidyl ethanolamine; the phospholipid facilitates incorporation of the peptide into liposomes. The agent stimulates macrophages to seek out and destroy cancer cells. The compound was originated by Novartis (formerly CIBA-Geigy), and is being developed by IDM Pharma for osteosarcoma. Mifamurtide is being reviewed by regulatory authorities in the US and EU for this indication. CIBA-Geigy originally developed mifamurtide in the early 1980s and the agent was subsequently outlicensed to Jenner Biotherapies in the 1990s. IDM Pharma acquired the rights to the drug from Jenner in April 2003. IDM and Genesis Pharma have entered into an exclusive licensing and marketing agreement for mifamurtide in South East Europe. Under the agreement terms, IDM will receive an upfront fee from Genesis, as well as milestone payments on reaching certain sales levels in the territory.
