Brentuximab Vedotin in CD30 Positive Epstein Barr Virus (EBV) Positive DLBCL of Elderly
The main purpose of this study is to test if brentuximab vedotin has an effect on cancer in patients with a certain type of large B-Cell Lymphoma. The side effects (unwanted effects) of SGN-35 in patients with this certain type of large B-Cell Lymphoma will also be studied. It is not known if brentuximab vedotin is better or worse than other treatment that might be given.

- Objective Response Rate (ORR) [ Time Frame: 36 months ] [ Designated as safety issue: No ]The primary efficacy parameter is objective response rate, defined as the proportion of patients with complete response (CR) and partial response (PR). To evaluate the activity of Brentuximab vedotin in patients with refractory/relapsed EDLBCLE using modified International Working Group (IWG) response criteria for malignant lymphoma. Measurable lesions: Lesions that can be measured accurately in at least one dimension (longest diameter to be recorded) as ≥20 mm with conventional techniques, or as ≥10 mm with spiral CT scan. Nonmeasurable lesions: Lesions not classified as measurable lesions (longest diameter ≤20 mm with conventional techniques or ≤10 mm with spiral CT scan. Frequencies and percentages will be used to summarize for all response categories. The ORR, our primary endpoint, and its 95 confidence interval will be calculated using the exact binominal method.
- Time to Response (TTR) [ Time Frame: 36 months ] [ Designated as safety issue: No ]Evaluate time to response. Time to Response (TTR) will be measured as the time from the start of treatment to the first time when the measurement criteria for CR or PR are met. Patients who did not have a confirmed response will be censored at the date of the last tumor assessment. For time to response, the median time and its 95% confidence intervals will be estimated using the Kaplan-Meier method.
- Duration of Response (DOR) [ Time Frame: 36 months ] [ Designated as safety issue: No ]Assess duration of response. DOR will be defined as the number of days between the first tumor response assessment of objective response (complete response and partial response) to the time of the first tumor response assessment of progressive disease (PD) or death if due to disease progression (date of first PD assessment or death due to disease progression-date of first objective response assessment +1). Participants who respond and have not progressed while on study or died for reasons other than disease progression will be censored at the date of the last disease assessment. The corresponding Kaplan-Meier curves will also be generated. For the treatment responders, descriptive statistics (mean, median, standard deviation and range) of will be used to summarize duration of response.
- Time to Disease Progression [ Time Frame: 36 months ] [ Designated as safety issue: No ]Estimate time to disease progression. For those with disease progression, time to disease progression will be reported. Time to Progression (TTP) will be defined as the number of days from the start of treatment to the date of disease progression based on tumor assessments made according to the 2007 IWG criteria.
- Progression Free Survival (PFS) Rate [ Time Frame: 36 months ] [ Designated as safety issue: No ]Evaluate progression-free survival. PFS will be calculated as the number of days between first administration of Brentuximab vedotin to the date of evidence of disease progression (date of positive test, e.g. Bone marrow biopsy or CT or PET scan), or death, regardless of cause, date of progressive disease or death-date of first administration of Brentuximab vedotin. Participants who are alive without a disease response assessment of progressive disease will be censored at the disease assessment date. Participants with missing tumor assessment(s) during treatment will be considered as having disease progression on the date of the actual assessment of disease progression. For PFS, the median time and its 95% confidence intervals will be estimated using the Kaplan-Meier method.
- Overall Survival (OS) Rate [ Time Frame: 36 months ] [ Designated as safety issue: No ]Estimate overall survival. OS will be defined as the time from the date of start of treatment until death as a result of any cause. For OS, the median time and its 95% confidence intervals will be estimated using the Kaplan-Meier method.

Experimental: Brentuximab vedotin Treatment
Participants will have screening tests up to 4 weeks before study treatment and dosing for up to 48 weeks. Brentuximab vedotin will be given with a dose of 1.8 mg (per kilogram of participant's body weight) intravenously (an IV through their vein) every 21 days, over 30 minutes for 16 cycles. Follow-up assessments will be performed up to 104 weeks (2 years).
Drug: brentuximab vedotin
Brentuximab vedotin will be given intravenously as outlined in treatment arm.
Brentuximab vedotin is a type of drug called an antibody drug conjugate (ADC). ADCs usually have 2 parts; a part that targets cancer cells (the antibody) and a cell killing part (the chemotherapy). Antibodies are proteins that are part of the immune system. They can stick to and attack specific targets on cells. The antibody part of brentuximab vedotin sticks to a target called CD30. CD30 is an important molecule on some cancer cells (including non-Hodgkin lymphoma) and some normal cells of the immune system. The cell killing part of brentuximab vedotin is a chemotherapy called monomethyl auristatin E (MMAE). After the brentuximab vedotin attaches to the CD30 part of the cell, the MMAE enters the cell and kills it.
More than 350 people with cancer have already been given brentuximab vedotin in research studies. These research studies were done to test the safety of different doses of brentuximab vedotin and to find out if brentuximab vedotin is active against cancer.
