A Phase 2, Multicenter, Randomized, Open-label Study of MEDI-551 in Adults with Relapsed or Refractory Diffuse Large B-Cell Lymphoma (DLBCL)


  • Study type

  • Study phase

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The overall purpose of the study is to determine if MEDI-551, when used in combination with salvage chemotherapy, Ifosfamide-carboplatin-etoposide (ICE) or Dexamethasone-cytarabine (DHAP) in patients with relapsed or refractory DLBCL who are eligible for Autologous Stem Cell Transplant (ASCT), has superior efficacy compared to rituximab in the same population.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.
