简要总结
This phase I/II trial studies the side effects and the best dose of brentuximab vedotin when given together with gemcitabine hydrochloride and to see how well they work in treating younger patients with Hodgkin lymphoma that has returned or does not respond to treatment. Monoclonal antibodies, such as brentuximab vedotin, may find cancer cells and help kill them. Drugs used in chemotherapy, such as gemcitabine hydrochloride, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving brentuximab vedotin together with gemcitabine hydrochloride may kill more cancer cells.
详细描述
PRIMARY OBJECTIVES:
I. To estimate the maximum tolerated dose (MTD) and/or recommended Phase 2 dose of brentuximab vedotin in combination with gemcitabine administered every three weeks to children with relapsed or primary refractory Hodgkin lymphoma (HL).
II. To define and describe the toxicities of brentuximab vedotin in combination with gemcitabine administered on this schedule.
III. To determine the complete response (CR) rate after treatment with four cycles of gemcitabine with brentuximab vedotin among patients with relapsed or refractory HL.

结局指标
主要结局
The Number of Patients With Relapsed or Refractory HL Who Achieved Complete Response (CR)
时间窗: After 4 cycles (21 days per cycle) of protocol therapy
The number of patients who experienced complete Response (CR) within the first four cycles. By modern response criteria, those with partial response (PR) or stable disease with all target lesions with Deauville scores \<=3 after cycle 4 are also considered as CR. Patients were assessed after treatment with four cycles of gemcitabine with brentuximab vedotin. CR was only reported for Dose level 2 across both phases of study.
Maximum Tolerated Dose (MTD) for Brentuximab Vedotin
时间窗: During cycle 1 of protocol therapy (21 days)
MTD was determined as the maximum dose at which fewer than one-third of patients experience Dose Limiting Toxicities (DLT) as assessed by National Cancer Institute (NCI) CTCAE v 4.0 during Cycle 1 of therapy. Gemcitabine was administered on days 1 and 8 of a 21 day cycle at a fixed dose. Brentuximab vedotin was investigated at a starting dose of 1.4 mg/kg administered on day 1 and escalated if tolerated.
Adverse Events Graded According to National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) Version 4.0
时间窗: 13 months from first dose
The number of eligible patients assigned to receive brentuximab vedotin in combination with gemcitabine that experienced CTC Version 4, grade 3 or higher adverse events during Phase 1 and Phase 2.
