Obatoclax Mesylate, Rituximab, and Bendamustine Hydrochloride in Treating Patients With Relapsed or Refractory Non-Hodgkin Lymphoma

This study has been withdrawn prior to enrollment.
(No patients accrued.)

First received: November 9, 2010
Last updated: June 5, 2013
Last verified: June 2013
This phase I/II trial is studying the side effects and the best dose of obatoclax mesylate when given together with rituximab and bendamustine hydrochloride to see how well it works compared with rituximab and bendamustine hydrochloride alone in treating patients with relapsed or refractory non-Hodgkin lymphoma. Obatoclax mesylate may stop the growth of cancer cells by blocking some of the proteins needed for cell growth. Monoclonal antibodies, such as rituximab, can block cancer growth in different ways. Some find cancer cells and help kill them or carry cancer-killing substances to them. Others interfere with the ability of cancer cells to grow and spread. Drugs used in chemotherapy, such as bendamustine hydrochloride, also work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving obatoclax mesylate together with rituximab and bendamustine hydrochloride may kill more cancer cells

Primary Outcome Measures:
  • Maximum tolerable dose, defined as the dose level beneath which 2 or more of 6 patients experience DLT (phase I) [ Time Frame: 28 days ]
    Graded using CTCAE version 4 criteria. DLTs are defined as grade 3-4 neutropenia or thrombocytopenia that persists beyond day 42; grade 4 febrile neutropenia or infection; grade 3 febrile neutropenia or infection that fails to resolve within 7days, grade 3-4 somnolence, ataxia, or confusion that requires inpatient admission on day 1 for observation and prevents patient discharge from outpatient clinic, or other grade 3-4 non-hematologic toxicity excluding infection.

  • Change in median progression-free survival (PFS) (phase II) [ Time Frame: From 6 to 12 months ]
    Estimated using the method of Kaplan-Meier.

Secondary Outcome Measures:
  • Overall objective response rate (phase II) [ Time Frame: Up to 3 years ]
    95% confidence intervals will be provided.

  • PFS (phase II) [ Time Frame: From the date of start of therapy to disease progression or death, whichever occurs first, assessed at 2 years ]
    Estimated using the method of Kaplan-Meier.
