Primary Outcome Measures
NameTimeMethod
PFS Rate of Participants With CLL (Including CLL, Prior BCR Inhibitor Naive Participants), FL, and Non-FL iNHL at Week 24Week 24

PFS rate was assessed by IRC and defined per standardized criteria (2007 Cheson criteria) (for NHL) and IWCLL criteria (for CLL), as the percentage of participants not experiencing definitive progression or death. Disease progression was defined per standardized criteria (2007 Cheson criteria) as: evidence of any new disease; worsening of nodal or extra-nodal index lesions; unequivocal increase in the size of non-index lesions or non-measurable disease, size of the liver, spleen, or other organ; and a ≥ 25% increase from nadir in either monoclonal IgM concentration or total serum IgM quantitation. Disease progression was defined per standardized IWCLL criteria as: evidence of any new disease; worsening of index lesions, spleen or liver, or non-index disease; and decrease in platelet count or hemoglobin that is attributable to CLL. PFS rate was analyzed using KM estimates.

Progression-Free Survival (PFS) Rate of Participants With CLL After BCR Targeted Therapy, MCL, and DLBCL at Week 16Week 16

PFS rate was assessed by Independent Review Committee (IRC) and defined per standardized criteria (2007 Cheson criteria) (for NHL) and International Workshop on Chronic Lymphocytic Leukemia (IWCLL) criteria (for CLL), as the percentage of participants not experiencing definitive progression or death. Disease progression was defined per standardized criteria as: evidence of any new disease; worsening of nodal or extra-nodal index lesions; unequivocal increase in the size of non-index lesions or non-measurable disease, size of the liver, spleen, or other organ; and a ≥ 25% increase from nadir in either monoclonal immunoglobulin M (IgM) concentration or total serum IgM quantitation. Disease progression was defined per standardized IWCLL criteria as: evidence of any new disease; worsening of index lesions, spleen or liver, or non-index disease; and decrease in platelet count or hemoglobin that is attributable to CLL. PFS rate was analyzed using Kaplan-Meier (KM) estimates.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants With Hematology Postbaseline Toxicity Grade 3 or HigherFirst dose date up to the last dose date plus 30 days (maximum: 78.4 months)

Hematology toxicity at any time postbaseline was summarized according to the NCI CTCAE, version 4.03. The most severe graded abnormality was counted for each participant per test.

ANC = absolute neutrophil count; Hb = hemoglobin; WBC = white blood cells

Percentage of Participants With Serum Chemistry Toxicity Postbaseline Grade 3 or HigherFirst dose date up to the last dose date plus 30 days (maximum: 78.4 months)

Serum chemistry toxicity at anytime postbaseline was summarized according to the NCI CTCAE, version 4.03. The most severe graded abnormality was counted for each participant per test. ALT = alanine aminotransferase; ALP = alkaline phosphatase; AST = aspartate aminotransferase

Percentage of Participants Experiencing Treatment-Emergent Adverse EventsFirst dose date up to the last dose date plus 30 days (maximum: 78.4 months)

A treatment-emergent Adverse Event (AE) was defined as an AE that occurs in the period from the first dose of study treatment to 30 days after the last dose of study treatment or leads to discontinuation of study treatment. Participants were assessed for AEs according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 4.03.

DOR was defined as the interval from first documentation of CR or PR (or VGPR or MR for participants with LPL/WM) to earlier of first documentation of definitive disease progression or death from any cause. Per 2007 Cheson criteria, CR: complete resolution of all disease-related radiological abnormalities; PR: ≥50% reduction in SPD of longest diameters of all index lesions, no new lesions; VGPR: \>90% DFB in IgM, and other criteria for CR met; MR: ≥25% but \<50% DFB in IgM, no IFB in SPD of lesions, no new lesions.
