mandated)

33 patients No MTD for ibrutinib; thus 560 mg/d

continuously with standard RCHOP-21 18% febrile neutropenia 18 pts with DLBCL in the phase 2

IR-CHOP

100% ORR in the DLBCL (18/18) 15 CR and 3 PR 4/4 nonGCB – CR 5/7 GCB – CR

PK not affected for either ibrutinib or vincristine

A randomized phase III is ongoing –placebo controlled (NCT01855750) for non-GCB type

43


Summary about COO in DLBCL Increases understanding of the biology Helps predict prognosis but not particularly

well May guide therapy

New treatments with lenalidomide and ibrutinib are focusing on ABC-type

New techniques of GEP will enhance the clinical utility and “bring it to your hospital”

Prediction – you will use COO to “choose X”
