Study of Brentuximab Vedotin in Participants With Relapsed or Refractory Systemic Anaplastic Large Cell Lymphoma

ORR was defined as the percentage of participants with a complete remission (CR) or partial remission (PR) by Independent Review Facility (IRF) response assessment according to the International Working Group (IWG) Revised Response Criteria for Malignant Lymphoma. CR is defined as the disappearance of all evidence of disease and PR is defined as regression of measurable disease and no new sites.

DOR was defined as the time between initial response and documented tumor progression in the subset of participants who achieved an objective response, either CR or PR. DOR per IRF was based upon the radiological assessment of measured lesions from an independent review facility. DOR was censored on the date of the last disease assessment documenting absence of progressive disease (PD) for participants who were lost to follow-up, withdrew consent, started a new anticancer therapy other than stem cell transplant (SCT), or discontinued treatment due to undocumented PD after the last adequate disease assessment.

PFS is defined as the time from start of study treatment to first documentation of objective tumor progression or to death due to any cause, whichever comes first. PFS per IRF is based upon the radiological assessment from an independent review facility.

CRR is defined as percentage of participants with CR. CR is defined as the disappearance of all evidence of disease.

OS is defined as the time from start of study treatment to date of death due to any cause.

An adverse event (AE): any untoward medical occurrence in a participant administered a pharmaceutical product; the untoward medical occurrence does not necessarily have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of a medicinal (investigational) product whether or not it is related to medicinal product. TEAE was defined as any AE that started after the first administration of study drug in this continuation study. Serious TEAEs: defined as any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of an existing hospitalization, results in persistent or significant disability or incapacity, is a congenital anomaly/birth defect, or is a medically important event.
