Spots Global Cancer Trial Database for A Study of SGN-35 (Brentuximab Vedotin) of Patients With Relapsed or Refractory PMLBCL

Study Description

Brief Summary: Study Objectives Primary: • To determine the antitumor efficacy of single-agent Brentuximab vedotin (1.8 mg/kg administered intravenously every 3 weeks) as measured by the overall objective response rate in patients with relapsed or refractory primary mediastinal large B-cell lymphoma. Secondary: * To assess duration of tumor control, including duration of response and progression-free survival * To assess survival * To assess the safety and tolerability of Brentuximab vedotin Additional: • To assess disease-related symptoms Number of Planned Patients 20 patients will be enrolled in this study. Duration of the study The study duration is 18 months for enrollment and 2 years for the follow-up.

Detailed Description: Study Population Eligible patients are those with relapsed or refractory primary mediastinal large B-cell lymphoma. Patients must also have histologically-confirmed CD30-positive disease, fluorodeoxyglucose (FDG)-avid and measurable disease of at least 1.5 cm, an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1, and adequate hematologic, kidney, and liver function. Eligible patients must not previously have been treated with Brentuximab vedotin or previously received an allotransplant. In addition, patients must not have congestive heart failure, known cerebral/meningeal disease, or any active viral, bacterial, or fungal infection requiring treatment with antimicrobial therapy within 2 weeks prior to first study dose. Study Design This is a single-arm, open-label, multicenter, clinical trial to evaluate the efficacy and safety of Brentuximab vedotin as a single agent in patients with relapsed or refractory primary mediastinal large B-cell lymphoma. Brentuximab vedotin will be administered as a single IV infusion on Day 1 of each 21-day cycle. Measures of anti-cancer activity will be assessed using the revised response criteria for malignant lymphoma. CT scans (chest, neck, abdomen, and pelvis) will be performed at baseline and Cycles 2, 4, 7, 10, 13, and 16 and PET scans will be done at baseline and Cycles 4 and 7. Patients will have an EOT assessment 30 ± 7 days after receiving their final dose of study drug. Long-term follow-up assessments (including survival and disease status information) will be performed every 12 weeks until either patient death or study closure, whichever occurs first. Patients who discontinue study treatment with stable disease or better will have CT scans done every 12 weeks until disease progression. Test Product, Dose, and Mode of Administration Brentuximab vedotin, 1.8 mg/kg, administered via outpatient IV infusion on Day 1 of each 21-day cycle. Number of Planned Patients 20 patients will be enrolled in this study. Duration of Treatment Brentuximab vedotin will be administered as a single IV infusion on Day 1 of each 21-day cycle. Patients may continue on study treatment until disease progression or unacceptable toxicity. Patients who achieve stable disease or better should receive a minimum of 8, but no more than 16 cycles of study treatment. Duration of the study The study duration is 18 months for enrollment and 2 years for the follow-up. Efficacy Assessments Treatment response will be assessed by tumor imaging (spiral CT of neck, chest, abdomen, pelvis and PET scans) performed at protocol-specified timepoints. Determination of antitumor efficacy will be based on objective response assessments made according to the Revised Response Criteria for Malignant Lymphoma. Clinical response of progressive disease (PD), stable disease (SD), partial remission (PR), or complete remission (CR) will be determined at each assessment. Responses will be determined by investigator. Safety Assessments Assessment of safety during the course of this study will consist of the surveillance and recording of adverse events (AEs), recording of concomitant medication and measurements of protocol-specified physical examination findings and laboratory tests.
