Naxitamab, sold under the brand name Danyelza, is a medication used to treat neuroblastoma.[1] It is used in those who are at least a year old with disease in the bone that have not responded sufficiently to other treatment.[1] It is given by gradual injection into a vein.[1] It is used with a granulocyte-macrophage colony-stimulating factor (GM-CSF).[1]

Common side effects include infusion-related reaction, pain, fast heart rate, vomiting, cough, nausea, diarrhea, high blood pressure, tiredness, erythema multiforme, peripheral neuropathy, hives, fever, headache, injection site reaction, swelling, anxiety, and irritability.[1] Other side effects may include transverse myelitis and reversible posterior leukoencephalopathy syndrome (RPLS).[1] Use in pregnancy may harm the baby.[1] It is a monoclonal antibody that binds to GD2.[1]

Naxitamab was approved for medical use in the United States in 2020.[1] As of 2022 it is not approved in Europe or the United Kingdom.[2] In the United States 40 mg of medication costs about 23,000 USD as of 2022.[3]

Medical uses

Naxitamab is used in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF) to treat people one year of age and older with high-risk neuroblastoma in bone or bone marrow whose tumor did not respond to or has come back after previous treatments and has shown a partial response, minor response, or stable disease to prior therapy.[4]

Dosage

It is given at a dose of 3 mg/kg/day, up to a maximum of 150 mg/day.[1] It is given on days 1, 3, and 5 of each treatment cycle with cycles repeated every 4 weeks until complete or partial response, followed by 5 additional cycles every 4 weeks.[1] Subsequent cycles may be repeated every 8 weeks.[1]

History

The application for naxitamab was approved based on two clinical trials (Trial 1/NCT03363373 and Trial 2/NCT01757626) of 97 participants with high-risk neuroblastoma in bone or bone marrow.[4] The trials were conducted at four centers in the United States and in Spain.[4] Both trials enrolled participants who were previously treated for high-risk neuroblastoma in the bone or bone marrow.[4] Some participants were not responding to the previous therapies anymore and some participants experienced the return of the cancer.[4] Participants with cancer that was actively growing after their last therapy were not included in the trial.[4] All participants received naxitamab in combination with granulocyte-macrophage colony-stimulating factor (GM-CSF) according to the trial schedule.[4]

The U.S. Food and Drug Administration (FDA) granted the application for naxitamab priority review, breakthrough therapy, and, orphan drug designations.[5] The FDA issued a priority review voucher for this rare pediatric disease product application[5] and was later granted a priority approval.[6]

Legal status

Naxitamab was approved for medical use in the United States in November 2020.[7][8]
