}

4.5 mg / ml concentrate for solution for infusion dinutuximab
beta

What Qarziba is and what it is used for

Qarziba contains dinutuximab beta, which belongs to a group of medicines called “monoclonal antibodies”. These are proteins that you specifically recognize and bind to other unique proteins in your body. Dinutuximab beta binds to a molecule found on cancer cells called disialoganglioside 2 (GD2). This activates the body’s immune system so that it attacks the cancer cells.

Qarziba is used to treat neuroblastoma (a type of cancer) with a high risk of recurrence after a series of treatments, which include stem cell transplantation to rebuild the immune system. It is also used to treat recurrent neuroblastoma ( recurrence ) or which could not be completely treated with previous treatments.

Before treating a recurrence of neuroblastoma, the treating physician will stabilize the disease activity using other appropriate methods.

Your doctor will also decide if co-administration of a second drug, interleukin ‑2, is necessary to treat your cancer.

Neuroblastoma is a type of cancer that occurs in abnormal nerve cells in the body, especially in the glands above the kidneys. It is one of the most common cancers in children.

The drug is used in patients from 12 months of age.
