A Study of TAK-659 in Combination With Bendamustine (+/-Rituximab), Gemcitabine, Lenalidomide, or Ibrutinib for the Treatment of Participants With Advanced Non-Hodgkin Lymphoma

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to determine the maximum tolerated dose (MTD) or recommended Phase 2 dose (RP2D) of TAK-659 when administered in combination with bendamustine, bendamustine + rituximab, gemcitabine, lenalidomide, or ibrutinib.

Detailed Description
-----------------
The drug being tested in this study is called TAK-659. TAK-659 is being tested to treat people who have advanced non-Hodgkin lymphoma. This study will determine the MTD or RP2D for TAK-659 in combination with bendamustine, bendamustine + rituximab, gemcitabine, lenalidomide, and ibrutinib. The study will enroll approximately 96 participants. Participants will be assigned to one of the 5 combination cohorts: Dose Escalation Phase Cohort A: TAK-659 + Bendamustine Dose Escalation Phase Cohort B: TAK-659 + Bendamustine + Rituximab Dose Escalation Phase Cohort C: TAK-659 + Gemcitabine Dose Escalation Phase Cohort D: TAK-659 + Lenalidomide Dose Escalation Phase Cohort E: TAK-659 + Ibrutinib This study comprises 2 phases: a dose escalation phase and a safety expansion phase. Participants in all 5 cohorts (Cohorts A-E) will participate in the dose escalation phase of the study. Approximately 12 additional participants with advanced follicular lymphoma (FL) or marginal zone lymphoma (MZL) will be added to Cohort B, in the safety expansion phase. This multi-center trial will be conducted in North America and Europe. The overall time to participate in this study is approximately 30 months. Participants will make multiple visits to the clinic and will be followed up for safety for 28 days after the last dose of study drug.

Eligibility Criteria
-----------------
Inclusion Criteria: Male or female participants aged 18 years or older. In the dose escalation phase, histologically or cytologically confirmed diagnosis of advanced non-Hodgkin lymphoma (NHL) of any histology (with the exception of participants with Waldenström macroglobulinemia [WM] and chronic lymphocytic leukemia [CLL]). In the safety expansion phase for Cohort B, only participants with advanced FL or MZL will be included. Radiographically or clinically measurable disease with at least 1 target lesion per International Working Group (IWG) criteria for malignant lymphoma. In the dose escalation phase, participants who are refractory or relapsed after at least 1 prior line of therapy due to progression, intolerance, or physician/participant decision and for whom no effective standard therapy is available per the investigator's assessment. In the safety expansion phase for Cohort B in participants with FL or MZL, the prior line of therapy is limited to <=1. Either treatment naive to, relapsed/refractory to, or experienced treatment failure due to other reasons with ibrutinib, idelalisib, or any other investigational B-cell receptor (BCR) pathway inhibitors not directly targeting spleen tyrosine kinase (SYK). Pre induction salvage chemotherapy and autologous stem cell transplant (ASCT) should be considered 1 therapy. Any consolidation/maintenance therapy after a chemotherapy regimen (without intervening relapse) should be considered 1 line of therapy with the preceding combination therapy. Maintenance antibody therapy should not be considered a line of therapy. For aggressive NHL (i.e., diffuse large B-cell lymphoma [DLBCL]), single-agent anti-CD20 monoclonal antibody therapy should not be considered a line of therapy. Antibody therapy in participants with indolent NHL (i.e., FL) given as a single agent after disease progression from a prior treatment should be considered a line of therapy. For participants with DLBCL transformed from indolent lymphoma, any treatment received for the indolent disease before the transformation to DLBCL will, in general, not count toward the 2 to 3 prior lines of therapy required for DLBCL in this study. Prior treatment with a regimen that includes the combination drug will not necessarily exclude a participant from that cohort if the investigator views treatment with that agent as appropriate. However, a participant who has a contraindication for a particular combination agent or who has been discontinued from prior therapy with a particular agent for toxicity will not be eligible for inclusion in that particular cohort. Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1 and life expectancy of greater than 3 months. Participants must have adequate organ function, including the following: Adequate bone marrow reserve: absolute neutrophil count (ANC) greater than or equal to (>=) 1000 per micro liter (/mcL), platelet count >=75,000/mcL (>=50,000/mcL for participants with bone marrow involvement), and hemoglobin >=8 gram per deciliter (g/dL) (red blood cell [RBC] and platelet transfusion allowed >=14 days before assessment). Hepatic: total bilirubin less than or equal to (<=) 1.5×the upper limit of the normal range (ULN); alanine aminotransferase (ALT) and aspartate aminotransferase (AST) <=2.5×ULN. Renal: serum creatinine >=60 milliliter per minute (mL/min) as estimated by the Cockcroft-Gault equation. Others Lipase <=1.5×ULN and amylase <=1.5×ULN with no clinical symptoms suggestive of pancreatitis or cholecystitis. Blood pressure <=Grade 1 (hypertensive participants are permitted if their blood pressure is controlled to <= Grade 1 by hypertensive medications and glycosylated hemoglobin is <=6.5%). Fasting serum glucose level shall be controlled to 130 milligrams per deciliter (mg/dL) during the screening period. Female participants who: Are postmenopausal for at least 1 year before the screening visit, or Are surgically sterile, or If they are of childbearing potential, agree to practice 1 highly effective method of contraception and 1 additional effective (barrier) method at the same time, from the time of signing the informed consent through 180 days after the last dose of study drug, or Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the participant. (Periodic abstinence [example, calendar, ovulation, symptothermal, postovulation methods] withdrawal, spermicides only, and lactational amenorrhea are not acceptable methods of contraception. Female and male condoms should not be used together.) Male participant, even if surgically sterilized (that is, status postvasectomy), who: Agree to practice effective barrier contraception during the entire study treatment period and through 180 days after the last dose of study drug, or Agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the participant.

Female and male condoms should not be used together.) Women of childbearing potential (WOCBP) must have a negative serum pregnancy test (minimum sensitivity 25 international units per liter IU/L or equivalent units of human chorionic gonadotropin [hCG]) at screening. Both men and women in the rituximab combination arm (Cohort B) must practice contraception as described above from the time of signing of the informed consent form (ICF) through 12 months after the last dose of study drug. Female participants should not donate ova from the time of signing the informed consent through 180 days after the last dose of study drug. Male participants should not donate sperm from the time of signing the informed consent through 180 days after the last dose of study drug. Both men and women in the lenalidomide combination arm (Cohort D) must adhere to the guidelines of the RevAssist program (United States participants) or, if not using commercial supplies, must adhere to the Lenalidomide Pregnancy Risk Minimisation Plan as outlined in the Study Manual. Both men and women in the lenalidomide combination arm (Cohort D) must adhere to the guidelines of the RevAssist program (United States participants) or, if not using commercial supplies, must adhere to the Lenalidomide Pregnancy Risk Minimisation Plan as outlined in the Study Manual. Voluntary written consent must be given before performance of any study-related procedure not part of standard medical care, with the understanding that consent may be withdrawn by the participant at any time without prejudice to future medical care.

| Dose Escalation Phase: Maximum Tolerated Dose (MTD) of TAK-659 | MTD was defined as the maximum dose that is determined to be safe and tolerable in different cohorts. Each cohort (A, B, C, D and E) received different escalating doses of TAK-659 in combination with other drugs. For each cohort the maximum tolerated dose of TAK-659 in combination with the other drug/s from the selected dose range is reported. | Cycle 1 (Cohorts A, B and C - each cycle was of 21 days and Cohorts D and E - each cycle was of 28 days) | 
| Dose Escalation Phase: Recommended Phase 2 Dose (RP2D) of TAK-659 | The RP2D was the MTD or less. The dose recommended for use in phase 2 studies was analyzed on the basis of the safety, tolerability, and preliminary pharmacokinetic (PK) and efficacy data obtained in phase 1 studies. Each cohort (A, B, C, D and E) received different escalating doses of TAK-659 in combination with other drugs. For each cohort the recommended Phase 2 dose of TAK-659 in combination with the other drug/s from the selected dose range is reported. | Cycle 1 (Cohorts A, B and C - each cycle was of 21 days and Cohorts D and E each cycle was of 28 days) |
