Bortezomib Plus CHOP Every 2 Weeks for Advanced Stage DLBCL

Lymphoma, B-Cell Clinical Trial

Official title: A Phase I/II Study of Bortezomib Plus CHOP Every 2 Weeks in Patients With Advanced Stage Diffuse Large B-cell Lymphomas

Status Completed

Clinical Trial Summary

Diffuse large B-cell lymphoma is a most prevalent non-Hodgkin's lymphoma. Recently the clinical results have been improved with new drugs and new modalities such as cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) every 2 weeks. Bortezomib is well known to be effective for multiple myeloma and has been being tried for other malignancies including lymphoma. The investigators will incorporate Bortezomib to CHOP every 2 weeks to further improve the clinical efficacy in diffuse large B-cell lymphoma.

Clinical Trial Description

Intended number of patients: 63 patients in total

• Phase I: 9 patients for 3 levels

• Phase II: 50 patients plus 3 patient from Phase I at MTD level

• Plus 4 patients: considering 5% follow-up loss rate

Study design and methodology:

For phase I, 9 patients; 3 levels of bortezomib (1.0, 1.3 and 1.6 mg/m2), 3 patients at each dose level.

If escalation of bortezomib beyond 1.0 mg/m2 is not possible, the trial will be stopped.

For phase II, 53 patients (3 from phase I at MTD level); Reject when complete response rate equal or less than 12/19 or 37/53 by Simon two-stage optimal phase II design.

Treatments:

• Bortezomib:

For phase I, 3 dose levels (1.0, 1.3 or 1.6 mg/m2), days 1 and 4, every 2 weeks.

For phase II, suggested dose of Bortezomib through phase I, days 1 and 4, every 2 weeks.

• CHOP2: cyclophosphamide 750mg/ m2 day 1, vincristine 1.4 mg/ m2 (max. 2 mg) day 1, doxorubicin 50 mg/ m2 day 1, prednisolone 100 mg days 1-5, every 2 weeks.

• G-CSF: Lenograstim 5 microgram/kg subcutaneously days 4-13 every 2 weeks. ;
