|Official Title:||Phase II Trial of Ofatumumab and Bortezomib in Subjects With Relapsed Cluster of Differentiation Antigen 20 (CD20)+ Diffuse Large B Cell Lymphoma, Follicular Lymphoma, or Mantle Cell Lymphoma|
- Response Rate of Ofatumumab in Combination With Bortezomib in Patients With Relapsed CD20+ (Cluster of DIfferentiation Antigen 20) Diffuse Large B Cell Lymphoma, Follicular Lymphoma, or Mantle Cell Lymphoma [ Time Frame: Every 2 cycles during treatment and then every 3 months for 2 years ]Based on International Working Group (IWG) criteria, recorded in four categories: Complete Response (CR), disappearance of all evidence of disease; Partial Response (PR), regression of measurable disease and no new sites of disease; Progressive Disease (PD), Any new lesion or increase by >= 50% of previously involved sites from nadir. Stable Disease (SD), failure to attain CR/PR or PD. A response is defined to be either CR/PR. A failure in response includes SD/PD.
- Overall Survival [ Time Frame: Up to every 3 months for 2 years ]This outcome measure is defined as the time from initiation of treatment to death due to any cause.
- Progression Free Survival [ Time Frame: Up to every 3 months for 2 years ]This outcome measure is defined as the length of time after treatment during which the patient survives with no sign of the disease.
- Disease Free Survival [ Time Frame: Up to every 3 months for 2 years ]The period of time between complete remission and recurrence of disease.
- Number of Participants With Adverse Events (Toxicity) [ Time Frame: Days 1, 8, and 15 of each course and 4-6 weeks after final treatment ]Toxicities and adverse experiences will be assessed at each visit using the NCI Common Toxicity Criteria for Adverse Events v4.0 Interim analyses on toxicity will be implemented based on the toxicity endpoints of the first 6 patients, and will be conducted sequentially 4 weeks after the treatment of each patient, or when serious toxicity has been observed for the patient, whichever comes earlier. we assume a non-informative prior distribution (Beta (0.001, 0.001)) for toxicity rate, and compute the posterior distribution of toxicity rate sequentially.

Experimental: Ofatumumab with Bortezomib
Ofatumumab was given intravenously on cycle 1 day 1 at a dose of 300mg, followed by a cycle 1 day 8 dose of 1000mg. During cycles 2 through cycle 6, Ofatumumab was given at a dose of 1000mg on day 1 of each cycle, with no dosing on any other day of the cycle. Bortezomib was given intravenously at a dose of 1.6mg/m2 on days 1, 8, and 15 of each cycle, following the Ofatumumab infusion, if given.
Other Names:Drug: Bortezomib
I. To determine the efficacy, as measured by overall response (complete response (CR) + partial response (PR)) of ofatumumab in combination with bortezomib in subjects with relapsed cluster of differentiation (CD)20+ DLBCL, FL or MCL.
I. To explore duration of efficacy of ofatumumab in combination with bortezomib in the same population as measured by progression free survival (PFS), overall survival (OS) and disease free survival (DFS).
II. To assess response as compared to prior treatment. III. To assess the safety and tolerability of ofatumumab in combination with bortezomib in the same patient population.
I. Correlation of trough ofatumumab blood levels to response. II. Correlation fragment crystallizable receptor (FcR) gamma 3 allotype and response.
Patients receive ofatumumab intravenously (IV) over 2.5 hours on days 1 and 8 of course 1, and day 1 of all subsequent courses. Patients also receive bortezomib IV over 3-5 seconds on days 1, 8, and 15. Treatment repeats every 28 days for up to 6 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment patients are followed up every 3 months for 2 years.
