Brief Summary:

The primary objective of the phase Ib of the study is to determine the recommended phase 2 dose (RP2D) for entospletinib (ENTO) in patients treated with R-CHOP.

The primary objective of the phase II is to determine the complete metabolic response (CMR) rate by the Lugano classification 2014 (Deauville scale 1-3) at the end of treatment.
