      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.

    4. Number of Participants With Anti-therapeutic Antibodies (ATA) to Brentuximab Vedotin [Day 1 of Cycle 1 and 3]

      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.

    5. Number of Participants With Markedly Abnormal Laboratory Values [Baseline up to 30 days after last dose of study drug (30 Days after Cycle 16)]

      The number of participants with any markedly abnormal standard safety laboratory values collected throughout study.

    6. Number of Participants With Clinically Significant Change From Baseline in Vital Signs [Baseline up to 30 days after last dose of study drug (30 Days after Cycle 16)]

      Vital signs included body temperature, body weight, blood pressure and heart rate.

    Title Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs)
    Description 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.
    Time Frame Baseline up to 30 days after last dose of study drug (30 days after Cycle 16)

    Adverse Events

    Time Frame Treatment-emergent adverse events are adverse events that started after the first dose of study drug and no more than 30 days after the last dose of study drug (30 days after Cycle 16).
    Adverse Event Reporting Description Serious and non-serious AEs were collected from first dose through 30 days after the last dose (Cycle 16). Beginning on Cycle 4 Day 1, only AEs with Grade 3 were recorded. Exceptions: New onset AEs of Grade 1-2 were recorded if they met criteria for SAEs or resulted in dose modification; PN events will be recorded regardless of severity grade.
