Brief Summary:

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).


Condition or disease Intervention/treatment Phase
Lymphoma, Large B-Cell, Diffuse Drug: Durvalumab Drug: Rituximab Drug: Doxorubicin Drug: Vincristine Drug: Cyclophosphamide Drug: Prednisone Drug: Lenalidomide Phase 2

Detailed Description:

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.

Primary Outcome Measures :
  1. Percentage of Participants Who Achieved a Complete Response (CR) at the End of Induction Therapy [ Time Frame: 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%.


Secondary Outcome Measures :
  1. Percentage of Participants Who Responded During Induction and Continued Into Consolidation Therapy (Database Cutoff Date: 02-Aug-2018) [ Time Frame: From first dose of study drug to completion of at least one cycle in the Consolidation Period (Day 1 up to Week 52) ]
    The percentage of participants who achieved a partial response (PR) or complete response (CR) at the end of Induction and continued into consolidation period 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 in outcome #1. PR was defined as a partial metabolic response and radiographic evidence showing ≥ 50% decrease in sum of perpendicular diameters (SPD) of up to 6 target measurable nodes and extranodal sites, no new lesions, spleen must have regressed > 50% in length beyond normal, and residual bone marrow involvement improved from baseline. Clopper-Pearson two-sided 95% confidence interval is reported. Null hypothesis was rejected if the lower limit of the confidence interval for the rate of subjects who continue consolidation therapy out of all subjects.

  2. Percentage of Participants Who Achieved a Clinical Response in the Biomarker Subpopulation for Immunohistochemistry (IHC) CD8 T-Cell Density [ Time Frame: Biomarker biopsies: Days -28 to Day -1. Clinical response: From first dose of study drug to end of Induction therapy (Day 1 up to Week 26 - maximum duration of Induction Period). ]
    Data in the analysis include all participants who received durvalumab, irrespective of the study arm in which they enrolled, because the selected biomarkers have been associated with response in other anti-PD1 or anti-PDL1 studies, such as durvalumab. IHC analysis was performed on the baseline tumor biopsy to quantify CD8 T-cell density. Participants with 'high' values, i.e. above the threshold defined as the median value of 774 cells/mm^2 found in commercial DLBCL samples using matched analytical methods, were predicted to be responders to treatment with durvalumab. The definition of a complete response was that used in the primary outcome.

  3. Percentage of Participants Who Achieved a Clinical Response in the Biomarker Subpopulation for Immunohistochemistry (IHC) Programmed Death Ligand - 1 (PDL1) Total Percentage [ Time Frame: Biomarker biopsies: Days -28 to Day -1. Clinical response: From first dose of study drug to end of Induction therapy (Day 1 up to Week 26 - maximum duration of Induction Period). ]
    Data in the analysis include all participants who received durvalumab, irrespective of the study arm in which they enrolled, because the selected biomarkers have been associated with response in other anti-PD1 or anti-PDL1 studies, such as durvalumab. IHC analysis was performed on the baseline tumor biopsy to quantify CD8 T-cell density. Participants with 'high' values, i.e. above the threshold defined as the median value of 774 cells/mm^2 found in commercial DLBCL samples using matched analytical methods, were predicted to be responders to treatment with durvalumab. The definition of a complete response was that used in the primary outcome.

  4. Percentage of Participants Who Achieved a Clinical Response in the Biomarker Subpopulation for Immunohistochemistry (IHC) Programmed Death Ligand - 1 (PDL1) Percentage of Tumor Cells [ Time Frame: Biomarker biopsies: Days -28 to Day -1. Clinical response: From first dose of study drug to end of Induction therapy (Day 1 up to Week 26 - maximum duration of Induction Period). ]
    Data in the analysis include all participants who received durvalumab, irrespective of the study arm in which they enrolled, because the selected biomarkers have been associated with response in other anti-PD1 or anti-PDL1 studies, such as durvalumab. IHC analysis was performed on the baseline tumor biopsy to quantify CD8 T-cell density. Participants with 'high' values, i.e. above the threshold defined as the median value of 774 cells/mm^2 found in commercial DLBCL samples using matched analytical methods, were predicted to be responders to treatment with durvalumab. The definition of a complete response was that used in the primary outcome.

  5. Percentage of Participants Who Achieved a Clinical Response in the Biomarker Subpopulation for the Interferon Gamma Score (IFNG-Score) From Ribonucleic Acid (RNA)-Sequencing Data [ Time Frame: Biomarker biopsies: Days -28 to Day -1. Clinical response: From first dose of study drug to end of Induction therapy (Day 1 up to Week 26 - maximum duration of Induction Period). ]
    Data in the analysis include all participants who received durvalumab, irrespective of the study arm in which they enrolled, because the selected biomarkers have been associated with response in other anti-PD1 or anti-PDL1 studies, such as durvalumab. IHC analysis was performed on the baseline tumor biopsy to quantify CD8 T-cell density. Participants with 'high' values, i.e. above the threshold defined as the median value of 774 cells/mm^2 found in commercial DLBCL samples using matched analytical methods, were predicted to be responders to treatment with durvalumab. The definition of a complete response was that used in the primary outcome.

  6. Participants With Treatment Emergent Adverse Events (TEAE) (Database Cutoff Date: 02-Aug-2018) [ Time Frame: From the date of the first dose of study drug to within 90 days after the last dose of durvalumab or 28 days after the last dose of any investigational product (IP) whichever is greater. Day 1 up to Week 54 at time of database cutoff date. ]
    An AE is any noxious, unintended, or untoward medical occurrence that may appear or worsen during a study. A serious AE is any AE occurring at any dose that: • Results in death; • Is life-threatening; • Requires or prolongs existing inpatient hospitalization; • Results in persistent or significant disability/incapacity; • Is a congenital anomaly/birth defect; • Constitutes an important medical event. The Investigator assessed the relationship of each AE to study drug and graded the severity according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE, Version 4.03): - Grade 1 = Mild (no limitation in activity or intervention); - Grade 2 = Moderate (some limitation in activity; no/minimal medical intervention required); - Grade 3 = Severe (marked limitation in activity; medical intervention required, hospitalization possible); - Grade 4 = Life-threatening; - Grade 5 = Death. Relation to IP is determined by the investigator.
