Activity of ibrutinib plus R-CHOP in diffuse large B-cell lymphoma: Response, pharmacodynamic, and biomarker analyses of a phase Ib study.

Introduction: This unplanned post-hoc analysis was based on data from the phase Ib DBL1002 study (NCT01569750) and evaluated the association between molecular biomarkers and clinical response to combined treatment with ibrutinib plus rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in diffuse large B-cell lymphoma (DLBCL) subtypes.

Methods: DLBCL subtyping was conducted using immunohistochemistry. Next-generation sequencing using immunoglobulin H primers assessed minimal residual disease (MRD).

Identification of potential ibrutinib combinations in hematological malignancies using a combination high-throughput screen.

Matrix high-throughput screening (HTS) methods are increasingly employed to rapidly define potential therapeutic drug combinations. We used combination HTS to identify compounds showing synergistic anti-proliferative activity with ibrutinib, an irreversible, small-molecule inhibitor of Bruton's tyrosine kinase. The goal was to identify ibrutinib combinations with maximum synergistic effects in heme malignancy lines, particularly in non-Hodgkin lymphoma including diffuse large B-cell lymphoma (DLBCL).

An Open-Label, Multicenter, Phase I/II Study of JNJ-40346527, a CSF-1R Inhibitor, in Patients with Relapsed or Refractory Hodgkin Lymphoma.

Purpose: This phase I/II study investigated JNJ-40346527, a selective inhibitor of the colony-stimulating factor-1 receptor (CSF-1R) tyrosine kinase as treatment for relapsed or refractory classical Hodgkin lymphoma (cHL).

Experimental Design: Patients ≥18 years with histopathologically confirmed initial diagnosis of cHL that had relapsed or was refractory after ≥1 appropriate therapies were assigned to sequential cohorts of oral daily doses of JNJ-40346527 (150, 300, 450, 600 mg every day, and 150 mg twice a day). For the dose-escalation phase, the primary endpoint was to establish the recommended phase II dose.
