Absorption, Distribution and Excretion
Due to rapid clearance from plasma, administration of mifamurtide is associated with a very low serum concentration of total (liposomal and free) drug. The mean AUC was 17.0 ± 4.86 h x nM and peak plasma concentration (Cmax) was 15.7 ± 3.72 nM following intravenous administration of 4 mg mifamurtide in healthy adult subjects. Variability in AUC and Cmax is reported to be low. As there was no quantifiable urinary excretion of mifamurtide and renal impairment has no clinically significant impact on drug pharmacokinetics, renal clearance is not expected to contribute to the total systemic clearance of mifamurtide. The mean volume of distribution at steady state (Vss) of total mifamurtide ranged from 225 to 28.7 healthy subjects after 4 mg intravenous infusion. There is no evidence of accumulation of L-MTP-PE or free MTP-PE (non-liposome-associated). The clearance from the plasma is rapid. Following 4 mg intravenous infusion, the mean clearance rate of total mifamurtide in healthy subjects ranged from 565 to 569 mL/min. Metabolism / Metabolites Metabolism of liposomal MTP-PE has not been studied in humans. The liposomes are mainly phagocytosed by the cells of the reticuloendothelial system (RES). Biological Half-Life Following intravenous administration of 4 mg mifamurtide in healthy adult subjects, the half life was 2.05 ± 0.40 hours. In pediatric and adult patients with psteosarcoma, the half life was 2.04 ± 0.456 hours after intravenous infusion of 2 mg/m^2. |

Pharmacodynamics
Mifamurtide stimulates the innate immunity by activating monocytes and macrophages. Within hours following administration of mifamurtide in healthy adults or patients with osteosarcoma NOS, elevated plasma levels of proinflammatory molecules, such as TNF-α, IL-6, and IL-1β, and other indicators of immune stimulation like C-reactive protein and neopterine were observed. _In vivo_ administration of mifamurtide in rat and mouse model resulted in inhibition of tumour growth of lung metastasis, skin and liver cancer, and fibrosarcoma. In addition, increased disease-free survival rate was demonstrated when mifamurtide was given as an adjuvant in dog models of osteosarcoma and hemangiosarcoma. Administration of mifamurtide was associated with transient neutropenia, usually when used in conjunction with chemotherapy. Pronounced inflammatory responses are uncommon. |

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
