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]

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]

Society and culture

Naxitamab was approved for medical use in the United States in November 2020.[5][6]
