What was measured

Metabolites of MMAE includes C4, C5, C7, C8 and C13. Amount of MMAE and its metabolites in urine were determined by multiplying the volume of urine obtained and the concentration of MMAE and its metabolites present in it, respectively. The LLQ for determining the concentration was 0.01 ng/mL.

Analysis population: PK analysis set included all participants who received brentuximab vedotin at 1.8 mg/kg throughout Cycles 1 to 3 and had sufficient dosing and PK data to reliably estimate PK parameters.

Groups in this outcome

Brentuximab Vedotin

Brentuximab vedotin 1.8 mg/kg, injection, intravenously, every 3 weeks on Day 1 of each 21-day treatment cycle up to a maximum of 16 brentuximab vedotin doses.

Brentuximab Vedotin + Rifampicin

Brentuximab vedotin 1.8 mg/kg, injection, intravenously, every 3 weeks on Day 1 of each 21-day treatment cycle up to a maximum of 16 brentuximab vedotin doses and rifampicin, 600 mg, capsules, orally, once daily from Day 1 of treatment Cycle 0 through Day 21 of treatment cycle 3.
