Condition diffuse large b-cell lymphoma
Treatments valproate, rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone
Phase phase 1/phase 2
Targets CD20, HDAC
Sponsor Lund University Hospital
Collaborator Valcuria
Start date June 2012
End date March 2018
Trial size 50 participants
Trial identifier NCT01622439, Version1.1


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.

Study Design

Intervention model single group assignment
Primary purpose treatment
Masking no masking
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.
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.
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.
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.
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.
Vill be given orally, 50 mg/m2, day 1-5 every cycle, for a total of 6 cycles.

Primary Outcomes

Establishment of maximum tolerable dose of valproate.
time frame: Participating patients will be followed during study treatment (6 cycles of chemotherapy); 12 weeks or 18 weeks depending on cycle length (14 or 21 days).
