About
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.

Adequate liver function defined as follows:
Adequate renal function as calculated by a creatinine clearance > 40 ml/min by local institutional formula
Patients with prior Hepatitis B must be given antiviral prophylaxis and hepatitis B virus (HBV) DNA monitored; Patients with prior Hepatitis C are eligible if, hepatitis C virus (HCV) RNA is undetectable.
Left ventricular ejection fraction (LVEF) ≥ 50% of echocardiography or multiple gated acquisition (MUGA) scan
Adequate tissue for central retrospective testing for cell of origin (10-15 slides of tumor biopsy must be available at baseline)

Heterosexually active males with partners of childbearing potential must agree to use reliable forms of contraception during treatment and up to 12 months after last treatment administration
Male subjects must agree to avoid sperm donation from Cycle 1 Day -4 until 12 months following the last treatment administration
Exclusion criteria
Central nervous system or meningeal involvement with DLBCL
Contraindication to any drug contained in the chemotherapy regimen
Prior treatment with Entospletinib or other spleen tyrosine kinase (SYK ) inhibitor
Patients with a prior history of other malignancy, exceptions include:
Patients taking current therapy with proton pump inhibitors and current therapy with medicines that are strong Cytochrome P450 3A (CYP3A) or CYP2C9 inducers, or moderate CYP2C9 inducers.

Active infection as judged by the investigator
Known hypersensitivity to ENTO
Congenital immunodeficiency or known HIV (human immunodeficiency virus infection) or active viral hepatitis B or C
Any other major illness that in the investigator's judgement, will substantially increase the risk associated with the subject's participation in the study
