Brief Summary
The primary objectives of this study are to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary efficacy of tirabrutinib (ONO/GS-4059) in combination with other targeted anti-cancer therapies and to evaluate the long-term safety of tirabrutinib as a monotherapy and in combination with other targeted anti-cancer therapies in adults with relapsed or refractory B-cell lymphoproliferative malignancies. This study consists of three parts: Dose Escalation, Dose Expansion, and Long-term Safety Monitoring. During the Dose Escalation phase, participants will be sequentially enrolled in a standard 3 + 3 dose escalation study design, to receive oral tirabrutinib combined with idelalisib entospletinib +/- obinutuzumab. The Dose Expansion Phase will enroll additional participants with a single B-cell lymphoproliferative malignancy disease type to further evaluate efficacy, safety, tolerability, PK, and pharmacodynamics. The Long-term Safety Monitoring phase will evaluate the long-term safety of tirabrutinib both as a monotherapy and in combination with other anti-cancer therapies. As of Amendment 9, all participants currently on the study who have no clinical evidence of disease progression will transition into long-term safety monitoring. Participants from the ongoing Study GS-US-401-1787 and participants who came off Study GS-US-401-1757 and Study GS-US-401-1787 but continued to receive treatment via named patient use (or individual expanded use) will be enrolled into the long-term safety monitoring group (Group VI). Participants enrolled in Group VI will continue the same treatment regimen in Study GS-US-401-1787 or named patient use (or individual expanded use). As of Protocol Amendment 8, the maximum treatment duration for any participant is an additional 6 years from the date of this amendment (ie. until November 2025). As of Amendment 9, entospletinib will be provided until 31 December 2020 to participants who are currently receiving entospletinib. Participants treated with entospletinib as part of a combination regimen with tirabrutinib will stop receiving entospletinib by 31 December 2020 but may continue to be treated with tirabrutinib monotherapy. Idelalisib will be provided as 50 mg tablets until 31 December 2020 and 100 mg tablets until study completion. Participants assigned to the 50 mg tablet will be given the option, at the investigator's discretion, to switch to 100 mg once daily idelalisib dose.

Outcome Measures
Primary Outcomes (4)
Percentage of Participants With Dose Limiting Toxicities (DLTs)
A DLT was defined as a ≥ Grade 3 AE that was assessed as related to study drug that occurred during the 28-day DLT assessment period with protocol-defined allowed exceptions. Any treatment-emergent adverse event (TEAE) that was, in the opinion of the Clinical Trial Steering Committee, of potential clinical significance such that further dosing exposed participants to unacceptable risk, was considered a DLT.
Up to 28 days
Objective Response Rate (ORR): Percentage of Participants With Complete Response (CR) or Partial Response (PR) at Week 12 in Participants With Non-Chronic Lymphocytic Leukemia (CLL) Type NHL
ORR for Waldenstrom Macroglobulinemia(WM):CR+VGPR+PR+MPR. CR: Absence of serum monoclonal IgM protein; normal serum IgM level: complete resolution of extramedullary disease, morphologically normal bone marrow/aspirate and trephine biopsy. Very good partial response (VGPR):Detectable monoclonal IgM; ≥90% reduction in serum IgM; Complete resolution of extramedullary disease; No new signs/symptoms. PR: Monoclonal immunoglobulin M (IgM) protein is detectable ≥50% but \<90% reduction in serum IgM level from baseline; reduction of extramedullary disease; no new signs or symptoms of active disease. Minor response (MPR):Detectable monoclonal IgM; ≥25% but \<50% reduction in serum IgM; No progression of extramedullary disease; No new signs/symptoms. Clopper-Pearson method was used in analysis. Data is reported by disease type: WM; Follicular Lymphoma (FL);Mantle Cell Lymphoma (MCL);Small Lymphocytic Lymphoma (SLL);Marginal Zone Lymphoma (MZL);Diffuse Large B-Cell Lymphoma (DLBCL) as applicable.
Week 12
ORR: Percentage of Participants With CR or PR in Participants With CLL at Week 24
ORR was defined as the percentage of participants who achieved a complete response (CR) or partial response (PR). CR and PR are defined in outcome measure#2. Clopper-Pearson method was used in outcome measure analysis. Percentages were rounded off.
Week 24
Percentage of Participants Experiencing Treatment-Emergent Adverse Events (TEAEs)
An AE was defined as any unfavorable and unintended sign, symptom, or disease temporally associated with the use of an investigational product or other protocol-imposed intervention, regardless of attribution. TEAEs were defined as an AE that onset in the period from the first dose of study treatment to 30 days after the last dose of study treatment. Percentages were rounded off.
