简要总结
This Phase 2, two-arm, open-label study is designed to evaluate the safety, clinical activity, and predictive biomarkers of durvalumab in combination with R-CHOP or R2-CHOP, followed by durvalumab consolidation therapy in previously untreated subjects with high-risk diffuse large B-cell lymphoma (DLBCL). Induction treatment with R-CHOP (± lenalidomide) will last for a total of up to 6 to 8 treatment cycles (21 day cycles), and the total time on study treatment, including durvalumab consolidation, will last up to 12 months.
On 05-Sep-2017, the US FDA has issued a Partial Clinical Hold on this study resulting in the discontinuation of enrollment into Arm B (Durvalumab + Lenalidomide + R-CHOP). After the US FDA Partial Clinical Hold, new eligible participants have been enrolled in Arm A (Durvalumab + R-CHOP).
详细描述
This research study is conducted in participants with previously untreated, high-risk diffuse large B-cell lymphoma (DLBCL). Patients with high-risk DLBCL typically have insufficient therapeutic outcomes. Therefore, the addition of novel agents to the currently used induction therapy (R-CHOP) is a rational approach to improve therapeutic outcomes in this disease setting.
Based on pre-clinical and clinical observations, it is hypothesized that durvalumab will have activity in DLBCL because the PD 1/PD L1 pathway is involved in the pathophysiology of DLBCL. In particular, the addition of durvalumab may augment the anti-tumor activity of R-CHOP against high-risk DLBCL sub-types.
The safety of durvalumab has already been explored. However, as there is limited clinical experience with durvalumab in DLBCL, the study is divided into two stages:
- A Safety Run-in Stage to evaluate the safety of the treatment combinations until at least 10 subjects are included in each of the two treatment arms
- An Expansion Stage to analyze the clinical activity of the treatment combinations
Results posted following Primary Outcome Completion date are based on a database cut-off of August 2, 2018.

结局指标
主要结局
Percentage of Participants Who Achieved a Complete Response (CR) at the End of Induction Therapy
时间窗: From first dose of study drug to end of Induction therapy (Day 1 up to Week 26 - maximum duration of Induction Period).
The primary efficacy analysis evaluated the complete response rate (CRR) at the end of the induction therapy in the efficacy evaluable population in a comparative manner against historical control. The response to treatment was assessed according to the 2014 International Working Group (IWG) Response Criteria for Non-Hodgkin's Lymphoma (NHL) (Cheson, 2014). CR was defined as a complete metabolic response and radiographic evidence showing target nodes/nodal masses regressed to ≤ 1.5 cm in longest diameter, no new lesions, regression of lymph nodes to normal size, absence of splenomegaly, and absence of bone marrow involvement. Clopper-Pearson two-sided 95% confidence interval is reported. Null hypothesis for the primary endpoint was rejected if the lower limit of the confidence interval for the complete response rate at the completion of the induction therapy in the efficacy evaluable population is above 55%.
