Risk Stratified Sequential Treatment for CD20-positive PTLD (PTLD-1/3)

Treatment of Patients With Posttransplant Lymphoproliferative Disorder (PTLD) With a Sequential Treatment Consisting of Anti-CD20 Antibody Rituximab and CHOP+GCSF Chemotherapy (PTLD-1/3)

This phase-II trial will investigate the efficacy, safety and the tolerability of a sequential therapy consisting of 4 courses of single agent rituximab followed by 4 courses of R-CHOP chemotherapy in patients with CD20+ posttransplant lymphoproliferative disorders (PTLD). However, responders to rituximab achieving a CR after the first 4 applications of rituximab will go on with rituximab monotherapy and will not receive chemotherapy.

Study Overview

• Status: Completed
• Conditions: Posttransplant Lymphoproliferative Disorder; PTLD
• Intervention / Treatment: Drug: rituximab monotherapy; Drug: sequential R-CHOP

Detailed Description

The rationale for performing the present study is to combine two highly active treatment modalities in first line therapy of solid organ recipients with B-cell PTLD. The monoclonal antibody CD20 represents an effective therapeutic approach in the treatment of PTLD. Unfortunately this effect seems to be of limited duration in some patients, who benefited from monotherapy with rituximab. The advantage of this therapeutic approach in PTLD is due to the low incidence of third to fourth degree adverse events. At diagnosis of PTLD a relevant proportion of these patients is not suitable for first line cytotoxic chemotherapy due to widespread disease, organ dysfunction or reduced performance state. Insufficiencies of kidney or bone marrow function are frequent in organ recipients due the toxic side effects of the immunosuppressive drugs. After pre-phase treatment with the monoclonal antibody rituximab the CHOP chemotherapy is suggested to be less toxic due to the lower tumor burden. Thereby treatment related severe or even lethal toxicities, frequently reported in patients with PTLD who underwent cytotoxic chemotherapy, may be prevented. Furthermore the total number of cytotoxic cycles of CHOP-therapy is reduced from 6 for 8 to 4 cycles and thus may result in an additional reduction of toxicity in the single patient. Because immunochemotherapy (R-CHOP) is clearly superior to CHOP with respect to progression free survival and relapse rates in patients with classical NHL and rituximab is very unlikely to add any further toxicity to CHOP the majority of patients will go on with four courses of R-CHOP. However, patients with a complete remission after 4 courses of single agent rituximab may have a very favourable risk profile and therefore will go on with rituximab single agent instead of R-CHOP.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
EXPERIMENTAL: A; All patients will receive 4 courses of rituximab on days 1, 8, 15 and 22. Patients achieving a CR after the first 4 applications of single agent rituximab (evaluated between day 40 to 50) will go on with 4 further courses of single agent rituximab on days 50, 72, 94 and 116.	Drug: rituximab monotherapy; 375 mg/m2, IV on days 1, 8, 15, 22, 50, 72, 94 and 116. In case of disease progression during the first 4 administration of rituximab antibody or the 4 weeks interval between course 4 and 5 the patients directly enter R-CHOP chemotherapy (Arm B).

Secondary Outcome Measures

Outcome Measure	Time Frame
The secondary objective is to determine the adverse events and tolerability of rituximab and/or chemotherapy. Furthermore, the long-term safety will be determined, especially the frequency of complicating infections and the overall survival.	within 2 years of follow up
