What is Dinutuximab?
What are the uses of this medicine?
- This medicine is used in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin-2 (IL-2), and 13-cis-retinoic acid (RA), for the treatment of pediatric patients with high-risk neuroblastoma who achieve at least a partial response to prior first-line multiagent, multimodality therapy.
How does this medicine work?
- Dinutuximab (din" ue tux' i mab) is a mouse-human chimeric monoclonal IgG1 antibody to disialoganglioside (GD2), a cell surface glycolipid that is present in low concentrations on skin, neural or peripheral nerve cells and is overexpressed on neuroblastoma cells.
- Engagement of dinutuximab with GD2 triggers antibody dependent cell cytotoxicity.
- Cytotoxicity of dinutuximab is increased by coadministration of granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin 2 (IL2) because of their effects on neutrophils, macrophages and immune effector cells, for which reason dinutuximab is usually combined with these cytokines.
