1. Overview



Summary

In high risk diffuse large B-cell lymphoma (DLBCL), International Prognostic Index (IPI)-score ≥ 3, 21% of patients will relapse within 2-years after completion of R-CHOP induction treatment despite achieving a complete remission. Patient relapsing within a year after R-CHOP treatment have a very poor prognosis, even after second line chemotherapy, with only 15% of patients achieving a long remission. Therefore, additional therapy in first line treatment is required for these patients. The immune checkpoint inhibitor atezolizumab is a monoclonal antibody directed against the program death ligand 1 (PDL1). The PD1 and PDL1 inhibitors have shown excellent results in relapsed Hodgkin lymphoma and promising results in relapsed B-cell non Hodgkin lymphoma. Given the acceptable toxicity profile of atezolizumab, this study examines the efficacy and toxicity of atezolizumab as consolidation treatment after R-CHOP induction in DLBCL patients at high risk of relapse.

Study objectives

Primary objective:
• To evaluate the 2-year disease free survival (DFS)

Secondary objectives:
• To evaluate toxicity and asses the relation of adverse events in time to recovery of the T-cell repertoire.
• To evaluate the 2-year overall survival (OS)
• To evaluate minimal residual disease (MRD) status at the end of induction therapy and at various time points during consolidation treatment.
• To evaluate the recovery of the T-cell and NK cell repertoire after induction therapy and at various time points during consolidation treatment in relation to toxicity and efficacy

Exploratory objectives
• To explore the PDL1/HLA expression, mutational load, gene expression immune profile, soluble PDL1, microbiome and T-cell clonality of patients in relation to MRD status and MRD conversion.
• To explore the tumor characteristics and mutational dynamics in patients who relapse.
• To assess the crossing of the blood-brain barrier of atezolizumab by measuring atezolizumab concentrations in het cerebrospinal fluid.


2. Patient eligibility criteria



Inclusion criteria

Inclusion criteria
• Age 18-75 (inclusive) years.
• Patients with a confirmed histologic diagnosis of diffuse large B-cell lymphoma (DLBCL-NOS) based upon a representative histology specimen according to the WHO classification, revision 2016
• Ann Arbor stages II-IV
• WHO performance status 0 – 1
• IPI ≥ 3 at diagnosis
• Complete metabolic remission (Deauville 1-3) after 6-8 cycles of R-CHOP according to the Lugano criteria
Of note:
1. Rituximab may have been administered either intravenously or subcutaneously. A rituximab biosimilar may have been used when it is approved for the indication of DLBCL.
2. Only dose reductions for vincristine are allowed during R-CHOP.
3. Central nervous system prophylaxis by intrathecal therapy is allowed.
4. 18F-FDG-PET scan should have been made 6-8 weeks after last induction cycle
• Negative pregnancy test at study entry.
• Patient is willing and able use adequate contraception during and until 5 months after the last protocol treatment.
• Written informed consent
• Patient is capable of giving a written informed consent.


Exclusion criteria

Diagnosis
• All histopathological diagnoses other than DLBCL-NOS according to the WHO classification, revision 2016, including:
High-grade B-cell lymphoma, with MYC and BCL2 and/or BCL6 translocations
Testicular large B-cell lymphoma
Primary mediastinal B cell lymphoma
Transformed indolent lymphoma
Post-transplant lymphoproliferative disorder.

Organ dysfunction
• Clinical signs of severe pulmonary dysfunction.
• Clinical signs of heart failure (NYHA classification II-IV).
• Symptomatic coronary artery disease or cardiac arrhythmias not well controlled with medication.
• Myocardial infarction during the last 6 months.
• Significant renal dysfunction (serum creatinine ≥ 150 umol/l or clearance ≤ 30ml/min
Creatinine clearance may be calculated by Cockcroft –Gault formula:
CrCl = [(140 – age [in years]) x weight (kg)] (x [0.85 if Female) / (0.815 x serum creatinine [μmol/L])
• Inadequate hematological function: hemoglobin < 5.5 mmol/L ANC < 1.0x109/L or platelets < 75x109 /L.
• Spontaneous INR > 1.5, aPTT >33.
• Significant hepatic dysfunction (total bilirubin ≥ 1.5x upper limit of normal (ULN) or transaminases ≥ 2.5 x ULN), unless related to Gilberts syndrome.
• Clinical signs of severe cerebral dysfunction.
• Patients with a history of uncontrolled seizures, central nervous system disorders or psychiatric disability judged by the investigator to be clinically significant and adversely affecting compliance to study drugs.
• Major surgery within the last 4 weeks.

Known or suspected infection
• Known active bacterial, viral, fungal, mycobacterial, parasitic, or other infection or any major episode of infection requiring treatment with IV antibiotics or hospitalization within 4 weeks before date of registration. Suspected active or latent tuberculosis needs to be confirmed by positive interferon gamma (IFN-γ) release assay.
• Patients known to be HIV-positive.
• Active chronic hepatitis B or C infection.
• Administration of a live, attenuated vaccine within 4 weeks before date of registration or anticipation that such a live attenuated vaccine will be required during the study and for a period of 5 months after discontinuation of atezolizumab.
