Conditions: Non-Hodgkin's Lymphoma
Keywords: diffuse large B cell mantle cell lymphoma
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 76
Healthy volunteers: no

Brief summary:
Primary Objective:

To determine the toxicity profile and maximum tolerated dose (MTD) of VELCADE when administered in combination with CHOP + Rituximab to patients with previously untreated diffuse large B cell or mantle cell non-Hodgkin's lymphoma (NHL)

Secondary Objectives:

To assess the response rate (overall and complete), event-free survival and overall survival with VELCADE and CHOP-R in patients with previously untreated diffuse large B cell or mantle cell lymphoma (phase II component)

Treatment:

Standard CHOP chemotherapy administered every 21 days (full dose) for six cycles

Rituximab administered (375 mg/m2) day 1 of each cycle (with usual premedications)

VELCADE is administered prior to rituximab and CHOP on day 1 of each cycle. The dose of VELCADE will be determined by the following dose escalation schedule:

Level Dose/Schedule (-2) 0.7 mg/m2 on day 1 of each cycle (-1) 0.7 mg/m2 on days 1 and 8 (0) 0.7 mg/m2 on days 1 and 4 (+1) 1.0 mg/m2 on days 1 and 4 (+2) 1.3 mg/m2 on days 1 and 4

Detailed description:
Standard CHOP chemotherapy administered every 21 days (full dose) for six cycles

Rituximab administered (375 mg/m2) day 1 of each cycle (with usual premedications)

VELCADE is administered prior to rituximab and CHOP on day 1 of each cycle. The dose of VELCADE will be determined by the following dose escalation schedule:

Once completed six cycles of therapy (\~18 weeks), patients will be evaluated every 3 months for the first year post treatment, then every 6 months until disease progression or death for years 2 through 5 post treatment. Patients who have disease progression will be contacted every 6 months until death to assess for survival status.

Arms:
arm 1: Standard CHOP chemotherapy administered every 21 days (full dose) for six cycles

Rituximab administered (375 mg/m2) day 1 of each cycle (with usual premedications)

VELCADE (Bortezomib) is administered prior to rituximab and CHOP on day 1 of each cycle. The dose of VELCADE will be determined by a dose escalation schedule.

Interventions: intervention 1: Bortezomib, CHOP, Rituximab
