Gemtuzumab ozogamicin for acute myeloid leukemia.

On 1 September 2017, the US Food and Drug Administration (FDA) approved gemtuzumab ozogamicin (GO) for the treatment of adults with newly diagnosed CD33 acute myeloid leukemia and for patients aged ≥2 years with CD33 acute myeloid leukemia who have experienced a relapse or who have not responded to initial treatment. This signals a new chapter in the long and unusual story of GO, which was the first antibody-drug conjugate approved for human use by the FDA.
