| Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) | An Adverse Event (AE) is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (example, a clinically significant abnormal laboratory finding), symptom, or disease temporally associated with the use of a drug, whether or not it is considered related to the drug. A treatment-emergent adverse event (TEAE) is defined as an adverse event with an onset that occurs after receiving study drug. A serious adverse event (SAE) is an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; or congenital anomaly; or a medically important event. AEs included both SAE and non-SAE. | Baseline up to 30 days after last dose of study drug (30 days after Cycle 16) | 
| Number of Participants With Anti-therapeutic Antibodies (ATA) to Brentuximab Vedotin | Participants with positive ATA at both Cycle 1 and 3, negative ATA at both Cycle 1 and 3, and transient positive (positive at one time point, but negative at the other) ATA for brentuximab vedotin were reported. | Day 1 of Cycle 1 and 3 | 
| Number of Participants With Markedly Abnormal Laboratory Values | The number of participants with any markedly abnormal standard safety laboratory values collected throughout study. | Baseline up to 30 days after last dose of study drug (30 Days after Cycle 16) | 
| Number of Participants With Clinically Significant Change From Baseline in Vital Signs | Vital signs included body temperature, body weight, blood pressure and heart rate. | Baseline up to 30 days after last dose of study drug (30 Days after Cycle 16) |
