Brief summary
This is a prospective single-arm, multi-center, phase II clinical trial to observe the efficacy and safety of R-CHOP (Rituximab-Cyclophosphamide, Epirubicin, Vincristine and Prednisone) combined with lenalidomide in the first-line treatment for patients with medium to high risk/high risk diffuse large B cell lymphoma.
Detailed description
Diffuse large B cell lymphoma (DLBCL) is the most common type of non-Hodgkin's lymphoma (NHL). Currently, R-CHOP is world-widely used in the first-line treatment for DLBCL. There are about one second of patients suffering relapse and drug resistance. Lenalidomide is an analog of thalidomide, the mechanism of anti-tumor action has not been fully elucidated. Lenalidomide has been proved to inhibit the proliferation of tumor cells in certain hematopoietic systems. At present, it has been approved for the treatment of multiple myeloma with good efficacy and safety. The goal of our trial is to assess the efficacy and safety of R-CHOP combined with lenalidomide in the first-line treatment for patients with medium to high risk/high risk diffuse large B cell lymphoma.
Interventions
Induction Chemotherapy: 375mg/m2, Intravenous administration on day 0 of each 3-week cycle until disease progression, stable disease after 2 cycles treatment, partial response after 4 cycles treatment or unacceptable toxicity develops, up to 6 cycles. Maintenance Treatment for patients with CR after 6 cycles: Rituximab, 375mg/m2, Intravenous administration on day 0 repeated every 3 weeks until disease progression or unacceptable toxicity develops, up to 2 cycles (Total 8 cycles).
Induction Chemotherapy: 25mg, oral administration on day 1 to 10 of each 3-week cycle until disease progression, stable disease after 2 cycles treatment, partial response after 4 cycles treatment or unacceptable toxicity develops, up to 6 cycles.
Induction Chemotherapy: 750mg/m2, Intravenous administration on day 1 of each 3-week cycle until disease progression, stable disease after 2 cycles treatment, partial response after 4 cycles treatment or unacceptable toxicity develops, up to 6 cycles.
Induction Chemotherapy: 70mg/m2, Intravenous administration on day 1 of each 3-week cycle until disease progression, stable disease after 2 cycles treatment, partial response after 4 cycles treatment or unacceptable toxicity develops, up to 6 cycles.
Induction Chemotherapy: 1.4mg/m2 (Max: 2mg), Intravenous administration on day 1 of each 3-week cycle until disease progression/stable disease after 2 cycles treatment, partial response after 4 cycles treatment or unacceptable toxicity develops, up to 6 cycles.
Induction Chemotherapy: 100mg, oral administration on day 1 to 5 of each 3-week cycle until disease progression/stable disease after 2 cycles treatment, partial response after 4 cycles treatment or unacceptable toxicity develops, up to 6 cycles.
Induction Chemotherapy: 1g/m2, Intravenous administration on day 3 of each 3-week cycle from 2 to 5 cycles for patients with high recurrence risk of the central nervous system.

Intervention model description
R-CHOP combined with Lenalidomide in the first-line treatment for patients with medium to high risk/high risk DLBCL. The individuals with the same propensity score according to high-risk factors (IPI score, double-expressor and P53 protein positive) were set as external control group (1:1) treated with R-CHOP.
