Elimination
About 24% of the total MMAE ingested as part of the ADC during an ADCETRIS infusion (1.8 mg/kg) was recovered in both urine and feces over a 7-day time frame. Of the recovered MMAE, approximately 72% was found in the feces and the majority of the excreted MMAE was excreted as unchanged drug. The liver is the primary route of clearance for MMAE.
