Study to Evaluate Safety and Efficacy of Blinatumomab in Subjects With Relapsed/Refractory (R/R) Aggressive B-Cell NHL
A Phase 2/3 Multi-center Study to Evaluate the Safety and Efficacy of Blinatumomab in Subjects With Relapsed/Refractory Aggressive B-Cell Non Hodgkin Lymphoma
This is a phase 2/3 open label, multicenter trial testing blinatumomab monotherapy for the treatment of subjects with Relapsed/Refractory (R/R) aggressive B-NHL not achieving CMR after 2 cycles of standard platinum-based chemotherapy regimens administered as S1. This study incorporates multiple interim analyses for futility, efficacy, and unblinded sample-size re-estimation. In the phase 3 part of the study, blinatumomab will be compared to Investigator's Choice chemotherapy.
In March 2019, decision made to not proceed with phase 3.
Study Overview
Detailed Description
This is a phase 2/3 open label, multicenter trial testing blinatumomab monotherapy for the treatment of subjects with R/R aggressive B-NHL not achieving CMR after standard platinum-based chemotherapy regimens administered as S1. This study incorporates multiple interim analyses for futility, efficacy, and unblinded sample-size re-estimation. In the phase 3 part of the study, blinatumomab will be compared to IC chemotherapy.The phase 2 component of the study will consist of up to a 28-day screening period, approximately 70 to 112 days of study treatment, a 30-day (+/- 3days) safety follow up, and long-term follow up that will conclude with the final analysis of the phase 3 component, estimated at 30 months after initiation of the phase 3 component. For the phase 3 component, the study will consist of up to a 28-day screening period, a treatment period of up to approximately 168 days, a 30-day safety follow-up visit, and long-term follow up. Long-term follow up will conclude with the final analysis.In the phase 2 component, enrolled subjects will receive blinatumomab monotherapy. In the phase 3 component, enrolled subjects will be randomized in a 1:1 ratio to blinatumomab or IC chemotherapy.
In March 2019, decision made to not proceed with phase 3.

|
ORR is inclusive of all participants who achieved CMR or those who achieved partial metabolic response (PMR), as determined by central radiographic assessment of PET/CT scans using the Lugano Classification.
