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

• Status: Terminated
• Trial end date: 2019-05-20
• Target enrollment: 0
• Participant gender: All

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.
