About Unituxin
Unituxin (dinutuximab) is a monoclonal chimeric antibody composed of murine variable heavy and light chain regions and the human constant region for the heavy chain kappa. Unituxin reacts specifically with the ganglioside GD2, which is highly expressed on the surface of the neuroblastoma cells and minimally expressed on the surface of normal human neurons, peripheral pain fibres, and skin melanocytes.

On 10 March 2015, Unituxin, in combination with GM-CSF, IL-2 and RA, became the first therapy to be approved by the US Food and Drug Administration for the treatment of paediatric patients with high-risk neuroblastoma who achieve at least a partial response to prior first-line multiagent multimodality therapy.
Unituxin carries a Boxed Warning alerting patients and health care professionals that Unituxin irritates nerve cells, causing severe pain that requires treatment with intravenous narcotics and can also cause nerve damage and life-threatening infusion reactions, including upper airway swelling, difficulty breathing, and low blood pressure, during or shortly following completion of the infusion. Unituxin may also cause other serious side effects including infections, eye problems, electrolyte abnormalities and bone marrow suppression.
