A Study of Idasanutlin in Combination With Obinutuzumab in Relapsed/Refractory (R/R) Follicular Lymphoma (FL) and in Combination With Rituximab in R/R Diffuse Large B-Cell Lymphoma (DLBCL) Participants

Study Overview
=================
Brief Summary
-----------------
This is a open-label, multicenter, non-randomized, study to evaluate the safety, efficacy, and pharmacokinetics of idasanutlin in combination with obinutuzumab in participants with R/R FL and rituximab in combination with idasanutlin in R/R DLBCL. The study will include an initial dose-escalation phase followed by an expansion phase. The dose-escalation phase is designed to determine the recommended phase 2 dose (RP2D) for idasanutlin in combination with obinutuzumab for FL and in combination with rituximab for DLBCL. The expansion phase is designed to further assess the safety and efficacy of obinutuzumab in combination with idasanutlin at the RP2D with the selected regimen in participants with R/R FL and of rituximab in combination with idasanutlin at the RP2D in participants with R/R DLBCL.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Percentage of Participants With Complete Response at the End of Induction, Determined by an Independent Review Committee (IRC) on the Basis of Positron Emission Tomography and Computed Tomography (PET-CT) Scans Using Modified Lugano 2014 Criteria | The plan was for the IRC to evaluate responses at the end of induction treatment in participants from the expansion phase using Lugano 2014 criteria for malignant lymphoma for a PET-CT-based complete response (CR), which required a complete metabolic response with a score of 1, 2, or 3 with or without a residual mass in lymph nodes and extralymphatic sites on the PET 5-point scale for 18-fluorodeoxyglucose (FDG) uptake (1 = no uptake above background; 2 = uptake less than or equal to [≤] mediastinum; 3 = uptake greater than [>] mediastinum and ≤ liver; 4 = uptake moderately > liver; 5 = uptake markedly > liver and/or new lesions). The CR criteria were slightly modified to require normal bone marrow by morphology (if indeterminate, immunohistochemistry negative). PET-CT scans were performed at end of induction only on participants who had received at least 2 cycles of induction treatment; those without a post-baseline tumor assessment were to be considered non-responders. | Within 6 to 8 weeks after Day 1 of Cycle 6 (up to approximately 28 weeks; 1 cycle is 28 days) | 

Secondary Outcome Measures

The CR criteria for participants with bone marrow involvement at screening required no evidence of FDG-avid disease in the marrow. PET-CT scans were performed at end of induction only on participants who had received at least 2 cycles of induction treatment; those without a post-baseline tumor assessment were considered non-responders. | Within 6 to 8 weeks after Day 1 of Cycle 6 (up to approximately 28 weeks; 1 cycle is 28 days) |

Any AEs that were not specifically listed in the NCI CTCAE, v4.0 were graded per the following 5 grades: Grade 1 = mild; asymptomatic or mild symptoms; clinical or diagnostic observations only; or intervention not indicated. Grade 2 = moderate; minimal, local, or non-invasive intervention indicated; or limiting age-appropriate instrumental activities of daily living. Grade 3 = severe or medically significant, but not immediately life-threatening; hospitalization or prolongation of hospitalization indicated; disabling; or limiting self-care activities of daily living. Grade 4 = life-threatening consequences or urgent intervention indicated. Grade 5 = death related to AE. The terms severe and serious are not synonymous and are independently assessed for each AE. Multiple occurrences of AEs were counted only once per participant at the highest (worst) grade. | From first dose until 90 days after the last dose of study drug treatment (up to 31 months) |

| Number of Participants by Electrocardiogram (ECG) Results Assessment Shift From Baseline to Specified Post-Baseline Timepoints | Single, resting, 12-lead ECG recordings were to be obtained after the participant had been resting in a supine position for at least 10 minutes. Any morphologic waveform changes or other ECG abnormalities were to be documented and clinical significance was determined based on the presence of symptoms, per the investigator's judgment. If the ECG assessment was missing at baseline then it was recorded as Missing. The ECG results assessments are presented as the shift from baseline to post-baseline assessments at each timepoint. BL = baseline; Cyc1, D1 = Induction Cycle 1 Day 1; Cyc4, D1 = Induction Cycle 4 Day 1; CS = Clinically Significant; EOI = End of Induction Treatment - Completion/Discontinuation; EOM = End of Maintenance Treatment - Completion/Discontinuation; MM1 = Maintenance Month 1; Unsched = Unscheduled Visit | Baseline, Induction Cycle 1 Day 1 and Cycle 4 Day 1, End of Induction (up to 6 cycles; 1 cycle is 28 days); Every 2 months during maintenance treatment from Months 1-23; End of Maintenance (up to 24 months); Unscheduled Visits (as clinically indicated) | 
| Hematology Laboratory Test Results Shift Table: Number of Participants by Highest NCI-CTCAE v4.0 Grade at Baseline to Highest Grade Post-Baseline | Clinical laboratory tests for hematology parameters were performed at local laboratories; any abnormal values (High or Low) were based on local laboratory normal ranges. Laboratory abnormalities are presented by the highest (worst) severity grade (according to NCI-CTCAE v4.0) at baseline to the highest grade post-baseline. Not every abnormal laboratory value qualified as an adverse event, only if it met any of the following criteria: clinically significant (per investigator); accompanied by clinical symptoms; resulted in a change in study treatment; or required a medical intervention or a change in concomitant therapy. For a patient with multiple post-baseline abnormalities, the highest (worst) grade for a given lab test is reported. Abs. = absolute count; BL = baseline; WBC = white blood cell count | From Baseline until 35 days after the last dose of study drug (up to 29 months) | 
| Blood Chemistry Laboratory Test Results Shift Table: Number of Participants by Highest NCI-CTCAE v4.0 Grade at Baseline to Highest Grade Post-Baseline | Clinical laboratory tests for blood chemistry parameters were performed at local laboratories; any abnormal values (High or Low) were based on local laboratory normal ranges. Laboratory abnormalities are presented by the highest (worst) severity grade (according to NCI-CTCAE v4.0) at baseline to the highest grade post-baseline. Not every abnormal laboratory value qualified as an adverse event, only if it met any of the following criteria: clinically significant (per investigator); accompanied by clinical symptoms; resulted in a change in study treatment; or required a medical intervention or a change in concomitant therapy. For a patient with multiple post-baseline abnormalities, the highest (worst) grade for a given lab test is reported. BL = Baseline; Blood Gluc., Fast. = blood glucose, fasting; SGOT/AST = serum glutamic-oxaloacetic transaminase/aspartate transaminase; SGPT/ALT = serum glutamic-pyruvic transaminase/alanine transaminase; Triacylglyc. Lipase = triacylglycerol lipase | From Baseline until 35 days after the last dose of study drug (up to 29 months) |
