A Study of Itacitinib (INCB039110) in Combination With Ibrutinib in Subjects With Relapsed or Refractory Diffuse Large B-Cell Lymphoma


About this study

The purpose of this study is to evaluate the safety/tolerability and efficacy of itacitinib in combination with ibrutinib in subjects with relapsed or refractory diffuse large B-cell lymphoma (DLBCL)

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Histologically documented diagnosis of DLBCL.
    • Phase 1: any DLBCL subtype.
    • Phase 2: activated B-cell or unclassifiable subtypes confirmed by immunohistochemistry using the Hans algorithm
  • Relapsed or refractory DLBCL, defined as having received at least 1 but no more than 3 prior treatment regimens and ineligible for high-dose chemotherapy/autologous stem cell transplant.
  • Fluorodeoxyglucose-avid disease (based on local evaluation) per the Lugano Classification. Fluorodeoxyglucose-avid disease is defined as disease with a 5-point scale score of 4 or 5.
  • Archived tumor tissue (block or 15-20 unstained slides) available, or be willing to undergo an incisional or excisional lymph node biopsy of accessible adenopathy (or, in less accessible lymph nodes, 4 to 8 core biopsies).
  • At least 1 measurable (≥ 2 cm in longest dimension) lesion on CT scan or magnetic resonance imaging (MRI).
  • Eastern Cooperative Oncology Group (ECOG) performance status 0 to 2.

Exclusion Criteria:

  • Transformed DLBCL or DLBCL with coexistent histologies (eg, follicular or mucosa-associated lymphoid tissue lymphoma).
  • Primary mediastinal (thymic) large B-cell lymphoma.
  • Known central nervous system lymphoma (either primary or metastatic).
  • Allogeneic stem cell transplant within the previous 6 months, or active graft versus host disease following allogeneic transplant.
  • Use of immunosuppressive therapy within 28 days of starting study treatment. Immunosuppressive therapy includes but is not limited to cyclosporine A, tacrolimus, or high-dose corticosteroids. Subjects receiving corticosteroids must be at a dose level ≤ 10 mg/day within 7 days of initiating study treatment.
  • Prior or concurrent therapy with a Janus kinase inhibitor or Bruton's tyrosine kinase inhibitor
