Valproate as First Line Therapy in Combination With Rituximab and CHOP in Diffuse Large B-cell Lymphoma

Lund University Hospital50 enrolled

Overview

Patients with previously untreated diffuse large B-cell lymphoma will receive standard treatment with R-CHOP (rituximab,cyclosphosphamide, doxorubicin, vincristine, and prednison) for 6 cycles, cycle length is 14 or 21 days. In addition, valproate is given three times daily day 1-3 in escalated doses. The rationale for adding valproate to standard treatment is invitro data indicating a sensitizing effect to chemotherapy, and an increase in CD 20-expression. Patients are included in 3+3 cohorts with escalation of valproate dose, planned dos levels are 30, 60, 80, 100, 120, 140 mg/kg/day. A total of 20 patients will be treated at the MTD.

Conditions

Diffuse Large B-cell Lymphoma

Interventions

Valproate is given in escalating doses to establish maximum tolerable dose when given together with standard treatment in patients with diffuse large B-cell lymphoma; this is the phase I part of the study. When maximum tolerable dose is established, this dose will be given to remaining patients in the phase II part of the study.

RituximabDRUG

Vill be given intravenously, 375 mg/m2, every second or third week depending on cycle length (14 or 21 days), for a total of 6 cycles.

CyclophosphamideDRUG

Vill be given intravenously, 750 mg/m2, every second or third week depending on cycle length (14 or 21 days) for a total of 6 cycles.

DoxorubicinDRUG

Vill be given intravenously, 50 mg/m2, every second or third week depending on cycle length (14 or 21 days), for a total of 6 cycles.

VincristineDRUG

Vill be given intravenously, 1.2 mg/m2, every second or third week depending on cycle length (14 or 21 days), for a total of 6 cycles.

PrednisoneDRUG

Vill be given orally, 50 mg/m2, day 1-5 every cycle, for a total of 6 cycles.
