Abstract
BACKGROUND: Daratumumab is a CD38 monoclonal antibody approved for treating relapsed/refractory and newly diagnosed multiple myeloma. Preclinical daratumumab studies demonstrated cytotoxic activity and reduced tumor growth in B-cell non-Hodgkin lymphoma (NHL) subtypes, including diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL), and mantle-cell lymphoma (MCL).

Note: Funding Information: The assay was verified on panels of commercially obtained formalin-fixed, paraffin-embedded lymphoma specimens; specimens were provided by Janssen, the Indiana University School of Medicine Simon Cancer Center, and the Cooperative Human Tissue Network (funded by the National Cancer Institute). The CD38 IHC assay was based on the EnVision Flex visualization technology and used the CD38 primary antibody, clone DAK-CD38 (Agilent Technologies, Carpinteria, CA).11 The assay staining protocol was developed for the Dako PT Link and Autostainer Link 48 automated IHC platform. After incubation with the CD38 antibody or the negative control reagent, specimens were incubated with a ready-to-use visualization reagent consisting of secondary antibody molecules and horseradish peroxidase molecules coupled to a dextran polymer backbone. The enzymatic conversion of the subsequently added diaminobenzidine chromogen resulted in precipitation of a visible reaction product localized to the antigen. Stained slides were then interpreted using a light microscope. For determination of CD38-positive staining, partial and/or complete linear circumferential membrane staining of neoplastic lymphocytes was included. Normal hematopoietic and necrotic cells were excluded from scoring. The total percentage of CD38-positive tumor cells was determined by qualitative assessment by a board-certified hematopathologist.G.S. reports grants, personal fees, and nonfinancial support from Celgene and grants and personal fees from Roche during the conduct of the study in addition to personal fees from Janssen, Gilead, Celgene, Novartis, Amgen, Servier, Bristol-Myers Squibb, Merck, MorphoSys, Roche, Acerta, and Pfizer outside the submitted work.
