Brief Summary:

Molecular imaging can be used for the noninvasive assessment of biodistribution of monoclonal antibodies. Atezolizumab has previously successfully been labeled with the radionucleotide Zirconium-89 (89Zr) and studied in solid malignancies (NCT02453984). The results of atezolizumab biodistribution can help to get a better understanding of the response mechanisms, the relation with minimal residual disease, the relation with the status of the T-cell and natural killer (NK)-cell repertoire and toxicity of programmed death ligand 1 (PDL1) checkpoint inhibition. Possibly in the future this will facilitate optimal patient selection. Sequential 89Zr-atezolizumab positron emission tomography (PET) scans can provide information on the dynamics of atezolizumab biodistribution over time. In combination with repeated characterization of tumor tissue and blood samples, these results can give inside in primary and acquired resistance.

In this parallel study of the HOVON 151 trial, 89Zr-atezolizumab-PET-scans will be used to evaluate 20 high risk DLBCL patients before and after induction (R-CHOP) therapy, and at suspected relapse during or after atezolizumab consolidation (HOVON 151).

Diffuse Large B-Cell Lymphoma, Not Otherwise Specified Other: 89Zr-atezolizumab PET scans Not Applicable

Detailed Description:

Patients with a high risk diffuse large B-cell lymphoma (DLBLC) with an international prognostic score (IPI) > 2, have a high risk of relapse even after achieving a metabolic complete remission with cyclophosphamide, doxorubicin, vincristine, prednisone and rituximab (R-CHOP) chemo-immunotherapy. Outcome after relapse is dismal. In patients with varies types of relapsed lymphoma checkpoint inhibition have shown promising results.

In order to improve outcome patients with a high risk DLBCL will be treated in the HOVON 151 trial (EudracT 2017-002605-35) with the monoclonal antibody directed against the immune checkpoint program death ligand 1 (PDL1) atezolizumab for 1 year after achieving a complete metabolic remission with R-CHOP.

The observed percentage of PDL1 positive tumor cells in DLBCL cases ranges from 13 to 31%. For PD-1/PDL1 checkpoint inhibition PDL1 tumor surface expression was proposed as a potential predictive marker. Despite higher overall response rates in PDL1 positive malignancies compared to PDL1 negative tumors, responses are seen in PDL1 negative patients nevertheless. PDL1 status from resected specimens showed a poor correlation to the PDL1 status from matched biopsies. Furthermore it has been shown that PDL1 expression in tumor biopsies changes with treatment. Therefore, PDL1 expression assessed by one single biopsy might not be representative.

Molecular imaging can be used for the noninvasive assessment of biodistribution of monoclonal antibodies. Atezolizumab has previously successfully been labeled with the radionucleotide Zirconium-89 (89Zr) and studied in solid malignancies (NCT02453984). The results of atezolizumab biodistribution can help to get a better understanding of the response mechanisms, the relation with minimal residual disease, the relation with the status of the T-cell and natural killer (NK)-cell repertoire and toxicity of programmed death ligand 1 (PDL1) checkpoint inhibition. Possibly in the future this will facilitate optimal patient selections. Sequential 89Zr-atezolizumab PET scans can provide information on the dynamics of atezolizumab biodistribution over time.

  2. Soluble programmed death ligand 1 (sPDL1) measurement using an enzyme-linked immunosorbent assay (ELISA). [ Time Frame: From 2 weeks before R-CHOP until 52 weeks after R-CHOP ]
    sPDL1 serum levels will be determined with ELISA

  3. Gene expression profiling (GEP) via Nanostring [ Time Frame: From 2 weeks before R-CHOP until 52 weeks after R-CHOP ]
    GEP via Nanostring analysis for cell-of origin will be perfomed on archival, paraffin fixed biopsies.

    Mutational analysis will be perfomed on archival, paraffin fixed biopsies.


Other Outcome Measures:
  1. T- and NK-cell dynamics in response to R-CHOP therapy [ Time Frame: From 2 weeks before R-CHOP until 52 weeks after R-CHOP ]
