Interval / dispersion
95% Confidence Interval
Time frame
Cycles 2, 4, 7, 10, 13 and 16 (21-day cycles) until disease progression, death or EOT and then every 12 weeks for 12 months after EOT, until disease progression, or death (Up to 27 months)

What was measured

EFS is defined as the time in months from first dose until any cause of treatment failure: disease progression, premature discontinuation of treatment for any reason, or death due to any cause, whichever occurs first. PD is defined as any new lesion or increase by \>50% of previously involved sites from nadir.

Analysis population: Safety population is defined as all participants who received at least 1 dose of study drug. EFS was censored on the last follow-up date if none of the above events occur during the study.

Groups in this outcome

Brentuximab Vedotin 1.4 mg/kg: Phase 1

Brentuximab vedotin 1.4 mg/kg, 30-minute IV infusion, Day 1 of every 21-day cycle, until there was evidence of disease progression or unacceptable toxicity.

Brentuximab Vedotin 1.8 mg/kg: Phase 1 and 2 r/r HL Only

Participants with r/r HL received brentuximab vedotin 1.8 mg/kg, 30-minute IV infusion, Day 1 of every 21-day cycle until there was evidence of disease progression or unacceptable toxicity (Up to 16 cycles). Treatment with brentuximab vedotin beyond 16 cycles was permitted at the joint discretion of the sponsor and the investigator for those participants experiencing continued clinical benefit.

Brentuximab Vedotin 1.8 mg/kg: Phase 1 and 2 r/r sALCL Only

Participants with r/r systemic anaplastic large-cell lymphoma (sALCL) received brentuximab vedotin 1.8 mg/kg, 30-minute IV infusion, Day 1 of every 21-day cycle until there was evidence of disease progression or unacceptable toxicity (Up to 16 cycles). Treatment with brentuximab vedotin beyond 16 cycles was permitted at the joint discretion of the sponsor and the investigator for those participants experiencing continued clinical benefit.
