Study of Bcl-2 Inhibitor BGB-11417 in Participants With Mature B-Cell Malignancies

Purpose

The purpose of this study is to determine the safety, tolerability; and to define the maximum tolerated dose (MTD) and Recommended Phase 2 Dose (RP2D); and to evaluate the safety and tolerability of the ramp-up dosing schedule and at the RP2D of BGB-11417 monotherapy, and when given in combination with zanubrutinib and obinutuzumab.

Inclusion Criteria

  • Confirmed diagnosis of one of the following: NHL Cohorts: 1. MZL i. R/R extranodal, splenic, or nodal MZL defined as disease that relapsed after, or was refractory to, at least one prior therapy ii. Active disease requiring treatment 2. FL i. R/R FL (Grade 1, 2 or 3a based on the WHO 2008 classification of tumors of hematopoietic and lymphoid tissue) and defined as disease that relapsed after, or was refractory to, at least 1 prior systemic therapy 3. DLBCL i. R/R DLBCL (including all subtypes of DLBCL) defined as disease that relapsed after, or was refractory to, at least two prior systemic therapies and has either progressed following or is not a candidate for autologous stem cell transplant (due to comorbidities or non-responsiveness to salvage chemotherapy) 4. Transformed indolent B-cell NHL i. Any lymphoma otherwise eligible for Part 1 that has transformed into a more aggressive lymphoma. Patients with transformation from CLL or SLL (Richter's transformation) are not eligible for Part 1 CLL/SLL Cohorts: 5. CLL/SLL diagnosis that meets the International Workshop on Chronic Lymphocytic Leukemia (IWCLL) criteria i. Disease characterized as Treatment Naive (TN) or R/R disease defined as disease that relapsed after, or was refractory to, at least 1 prior therapy ii. Requiring treatment as defined by history MCL cohorts: 6. WHO-defined MCL I. R/R MCL defined as disease that relapsed after, or was refractory to, at least 1 prior systemic therapy; ii. Requiring treatment in the opinion of the investigatorr WM cohorts: g. WHO-defined WM (clinical and definitive histologic diagnosis) i. R/R disease defined as disease that relapsed after, or was refractory to, at least 1 prior therapy; ii. Meeting at least 1 criterion for treatment according to consensus panel criteria from the Seventh International Workshop on Waldenström's Macroglobulinemia (Dimopoulos et al 2014) - Measurable disease by computed tomography (CT)/magnetic resonance imaging (MRI), defined as: 1. CLL: at least 1 lymph node > 1.5 cm in longest diameter and measurable in 2 perpendicular dimensions or clonal lymphocytes measured by flow cytometry 2. DLBCL, FL, MZL, SLL: at least 1 lymph node > 1.5 cm in longest diameter OR 1 extranodal lesion > 1.0 cm in the longest diameter, measurable in at least 2 perpendicular dimensions. For MZL, isolated splenomegaly is considered measurable for this study - Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 2 - Adequate organ function - Adequate pancreatic function indicated by: 1. Serum amylase ≤ 1.5 x upper limit of normal (ULN) 2. Serum lipase ≤ 1.5 x ULN

Exclusion Criteria

  • Known central nervous system involvement by lymphoma/leukemia - Known plasma cell neoplasm, prolymphocytic leukemia, history of or currently suspected Richter's syndrome - Prior therapy ≥ 2 months with or progression on a B-cell lymphoma-2 (Bcl-2) inhibitor NOTE: Other protocol defined Inclusion/Exclusion criteria may apply.
