Conditions: Non-Hodgkin's Lymphoma (NHL)

Interventions: Drug: Bendamustine hydrochloride
Drug: Ofatumumab

Registration Number: NCT01108341

Recruitment & Eligibility

Status: COMPLETED

Sex: All

Target Recruitment: 50

Inclusion Criteria

The patient has histopathologic confirmation of one of the protocol-specific CD20+ B-cell non-Hodgkin's lymphomas. Tissue diagnostic procedures must be performed within 6 months of study entry and with biopsy material available for review.
The patient meets 1 of the following need-for-treatment criteria:
1. Presence of at least 1 of the following B-symptoms:
  - fever (>38ºC) of unclear etiology
  - night sweats
  - weight loss of greater than 10% within the prior 6 months
2. large tumor mass (bulky disease) characterized by lymphomas with a diameter of more than 3 cm in 3 or more regions or by a lymphoma with a diameter of more than 7 cm in 1 region
3. presence of lymphoma-related complications
4. hyperviscosity syndrome due to monoclonal gammopathy
The patient's tumor is verified to be CD20+ positive from current or previous excisional or incisional tissue diagnostic procedures performed within 6 months of study entry.
The screening phase CT scan (based on local evaluation) shows:
2 or more clearly demarcated lesions with a largest diameter ≥1.5 cm, or
1 clearly demarcated lesion with a largest diameter ≥2.0 cm
The patient was not previously treated for indolent lymphoma (with the exception of a single course of local radiation therapy not exceeding 2 adjacent lymph node regions).
The patient has adequate hematologic and hepatic function.
The patient has Eastern Cooperative Oncology Group (ECOG) performance status 0, 1, or 2.
The patient has serum creatinine of 2.0 mg/dL or less or creatinine clearance of 30 mL/min or more, based on the Cockcroft-Gault method, or from a 24-hour urine collection.
The patient is willing to comply with contraception requirements.

Key

Exclusion Criteria

The patient:

Has small lymphocytic lymphoma or mantle cell lymphoma.

Has New York Heart Association (NYHC) Class III or IV heart failure, uncontrolled arrythmias or unstable angina, electrocardiographic evidence of active ischemia or active conduction system abnormalities, or myocardial infarction within the last 6 months.
Has known human immunodeficiency virus (HIV) infection.
Has acute or chronic hepatitis B or hepatitis C infection.
Is a pregnant or lactating woman. (Any women becoming pregnant during the study will be withdrawn from the study.)
Has any serious uncontrolled, medical or psychological disorder that would impair the ability of the subject to receive study drugs.

Primary Outcome Measures

Name	Time	Method
Percentage of Participants With a Best Overall Response of Complete Response (CR) or Partial Response (PR), as Determined by the International Working Group (IWG) Criteria As Assessed by Investigators	up to Week 32	The IWG criteria (Cheson et al 2007) for a CR is a complete disappearance of all detectable clinical evidence of disease and disease-related symptoms if present before therapy. A PR is at least a 50% decrease in sum of the product of the diameters (SPD) of up to 6 of the largest dominant nodes or nodal masses, no increase should be observed in the size of other nodes, liver or spleen, and no new sites of disease should be observed.
