Description of intervention(s) / exposure
Treatment: Drugs - Blinatumomab

Experimental: Blinatumomab - After a run-in period of up to 24 months to evaluate MRD status and assess eligibility for treatment assignment, participants received blinatumomab intravenous (IV) infusion at an initial dose of 9 µg/day for the first 7 days of treatment, escalated (dose-step) to 28 µg/day starting on Day 8 (Week 2), followed by a dose-step to 112 µg/day starting on Day 15 (Week 3) and continuing until completion of therapy (Day 57 of Cycle 1).
Cycle 1 of blinatumomab treatment is 12 weeks (84 days) in duration and includes 8 weeks (56 days) of blinatumomab IV infusion followed by a 4-week (28-day) treatment-free interval.


Treatment: Drugs: Blinatumomab
Blinatumomab is administered as a continuous IV infusion.

Summary
Brief summary
The study will estimate the MRD-negative response rate after treatment with blinatumomab in
subjects with high-risk DLBCL who are MRD-positive following aHSCT. The clinical hypothesis
is that the MRD-negative response rate will be greater than 10%. Achieving an MRD-negative
response rate of 30% would be of scientific and clinical interest.
