Brief Summary

The purpose of this study is to confirm whether the bispecific T-cell engager blinatumomab is effective and safe in the treatment of patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL).

Detailed Description

DLBCL is an aggressive malignant disease which evolves from B-cells and affects mainly the lymphatic tissue. Due to its aggressive nature the disease is characterized by a fast course which is lethal without therapy. Potentially curative therapy options are available even at advanced stages. Standard-first line leads to a high initial response rate (85-90%) and an approximate cure rate of 50% of patients. Patients refractory to or with early relapse after this treatment (10-15%) have a very poor prognosis.

Blinatumomab is a bispecific single-chain antibody derivative against CD19 and CD3, designed to link B-cells and T-cells resulting in T-cell activation and a cytotoxic T-cell response against CD19 expressing cells.

This study consisted of a screening period, treatment period, and a follow-up efficacy and survival period. The core study comprises the treatment period to the 30 days after the last infusion. The first cycle consisted of a continuous intravenous (CIV) infusion over 8 weeks. Participants who achieved a Complete Response (CR) or Partial Response (PR) or had stable disease after the first treatment cycle were eligible to receive a second (consolidation) cycle of treatment over 4 weeks, following a 4-week treatment-free interval. After the last treatment cycle, efficacy and survival follow-up visits occurred for up to 24 months from treatment start. Participants who relapsed during the follow-up period may have received an additional 8 weeks of treatment.

Two dose regimens were assessed in this study. Stage 1 comprised 2 dose cohorts. In Cohort 1, the first 6 participants were to receive blinatumomab in a dose-escalating manner: 9 µg/day for the first week, followed by 28 µg/day for the second week, then 112 µg/day for the remaining 6 weeks of treatment during Cycle 1. In Cohort 2, the next 6 participants enrolled were to receive a constant dose of 112 µg/day blinatumomab. Before the initiation of stage 2, a pre-planned data monitoring committee (DMC) meeting was held to assess the safety profile of Cohort 1 and Cohort 2. The dosing regimen with the more favorable benefit-risk profile was to be selected for Cohort 3.

Study Groups

Blinatumomab

By study design, two dose regimens were assessed in this study. In Stage 1, Cohort 1, participants received blinatumomab in a dose-escalating manner: 9 µg/day for the first week, followed by 28 µg/day for the second week, then 112 µg/day for the remaining 6 weeks of treatment during cycle 1. In Cohort 2, the next participants enrolled and received a constant dose of 112 µg/day blinatumomab. The dosing regimen with the more favorable benefit-risk profile was then selected for Stage 2, Cohort 3.
