Primary Outcome Measures:

Objective Response Rate (ORR) by Investigator [ Time Frame: Up to approximately 3 years ] [ Designated as safety issue: No ]
Percentage of participants who achieved a best response of complete response/remission (CR), CR without hematologic recovery (CRi; leukemia only), or partial remission (PR) per the applicable response criteria. Response criteria for solid tumors (by radiographic tumor imaging) per Response Evaluation Criteria for Solid Tumors (RECIST) 1.1 (Eisenhauer 2009); response criteria for leukemia (by peripheral blood and bone marrow aspirate or biopsy) per International Working Group (Cheson 2003).

Secondary Outcome Measures:

Complete Remission (CR) Rate by Investigator [ Time Frame: Up to approximately 3 years ] [ Designated as safety issue: No ]
Percentage of participants who achieved a best response of CR per the applicable response criteria. Response criteria for solid tumors (by radiographic tumor imaging) per Response Evaluation Criteria for Solid Tumors (RECIST) 1.1 (Eisenhauer 2009); response criteria for leukemia (by peripheral blood and bone marrow aspirate or biopsy) per International Working Group (Cheson 2003).
Duration of Objective Response by Kaplan-Meier Analysis [ Time Frame: Up to approximately 2 years ] [ Designated as safety issue: No ]
Duration of objective response (CR [+CRi; leukemia] + PR), defined as time of initial response until disease progression or death. Response criteria for solid tumors (by radiographic tumor imaging) per Response Evaluation Criteria for Solid Tumors (RECIST) 1.1 (Eisenhauer 2009); response criteria for leukemia (by peripheral blood and bone marrow aspirate or biopsy) per International Working Group (Cheson 2003).
Duration of Complete Response by Kaplan-Meier Analysis [ Time Frame: Up to approximately 2 years ] [ Designated as safety issue: No ]
Duration of CR, defined as time of initial response until disease progression or death. Response criteria for solid tumors (by radiographic tumor imaging) per Response Evaluation Criteria for Solid Tumors (RECIST) 1.1 (Eisenhauer 2009); response criteria for leukemia (by peripheral blood and bone marrow aspirate or biopsy) per International Working Group (Cheson 2003).
Progression-Free Survival by Kaplan-Meier Analysis [ Time Frame: Up to approximately 2 years ] [ Designated as safety issue: No ]
Progression-free survival, defined as time from start of study treatment to disease progression per investigator or death due to any cause
Adverse Events by Severity, Seriousness, and Relationship to Treatment [ Time Frame: Up to approximately 3 years ] [ Designated as safety issue: Yes ]
Counts of participants who had treatment-emergent adverse events (TEAE, defined as newly occurring or worsening after first dose on Study SGN35-013). Serious adverse events are reported from the time of informed consent. National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE version 4.03) were used to assess severity (1=mild, 2=moderate, 3=severe, 4=life-threatening/disabling, 5=fatal). Relatedness to study drug was assessed by the investigator (Yes/No). Participants with multiple occurrences of an adverse event within a category are counted once within the category.
Laboratory Abnormalities >/= Grade 3 [ Time Frame: Up to approximately 3 years ] [ Designated as safety issue: Yes ]
Counts of study participants with post-baseline laboratory abnormalities of Grade 3 or greater per NCI CTCAE version 4.03. Participants with multiple occurrences of a laboratory abnormality within a category are counted once in that category
Brentuximab Vedotin Antibody-Drug Conjugate (ADC) Concentration at End of Infusion (Ceoi) [ Time Frame: Up to approximately 3 years ] [ Designated as safety issue: No ]
Brentuximab Vedotin Antibody-Drug Conjugate (ADC) Trough Concentration (Ctrough) [ Time Frame: Up to approximately 3 years ] [ Designated as safety issue: No ]
Maximum Concentration (Cmax) of Brentuximab Vedotin Monomethyl Auristatin E (MMAE) [ Time Frame: Up to approximately 3 years ] [ Designated as safety issue: No ]
Brentuximab Vedotin Monomethyl Auristatin E (MMAE) Trough Concentration (Ctrough) [ Time Frame: Up to approximately 3 years ] [ Designated as safety issue: No ]
Incidence of Anti-therapeutic Antibodies (ATA) [ Time Frame: Up to approximately 3 years ] [ Designated as safety issue: Yes ]
Counts of participants with post-baseline anti-brentuximab vedotin antibodies. Persistently positive is defined as confirmed ATA in more than 2 post-baseline samples and transiently positive is defined as confirmed ATA in 1 or 2 post-baseline samples.
