Lenalidomide and Blinatumomab for the Treatment of Relapsed Non-Hodgkin Lymphoma

PRIMARY OBJECTIVE: I. To determine the maximum tolerated dose (MTD) of lenalidomide when given in combination with blinatumomab in the proposed regimen. SECONDARY OBJECTIVES: I. To observe and record anti-tumor activity anti-tumor response (complete response \[CR\] and partial response \[PR\] as per International workshop lymphoma response criteria). II. To investigate the immune response to blinatumomab alone and in combination with lenalidomide. III. To document the infection rate with a 96-hour bag change schedule for blinatumomab. OUTLINE: This is a dose-escalation study of lenalidomide. INDUCTION: Patients receive blinatumomab intravenously (IV) continuously on days 1-56 and lenalidomide orally (PO) on days 29-49 in the absence of disease progression or unacceptable toxicity. CONSOLIDATION: Patients achieving response including stable disease receive blinatumomab IV continuously on days 1-7 and lenalidomide PO on days 1-21. Treatment repeats every 28 days for up to 6 cycles in the absence of disease progression or unacceptable toxicity. MAINTENANCE: Patients receiving response including stable disease after completion of Consolidation receive lenalidomide PO on days 1-21. Cycles repeat every 28 days for up to 2 years in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 2 years.
