OLYMPIA-3 Trial Summary

This trial is testing an experimental drug (odronextamab) with chemotherapy to treat diffuse large B-cell lymphoma (DLBCL) in patients previously untreated, relapsed, or refractory. It will compare the effectiveness to the current standard of care to see how safe and tolerable it is.

Who is the study for?
This trial is for adults with a life expectancy of at least 12 months who have either not been treated for diffuse large B-cell lymphoma (DLBCL), or whose DLBCL has relapsed or not responded to treatment. They should have measurable disease, be reasonably fit (ECOG ≤2), and their organs must function well. People with another active cancer, severe medical conditions, recent major surgery, organ transplants, certain infections like COVID-19 or hepatitis, CNS involvement by lymphoma, prior anti-lymphoma therapy or allergies to study drugs cannot join.Check my eligibility
What is being tested?
The trial compares the effectiveness and safety of an experimental drug called odronextamab combined with chemotherapy versus rituximab combined with chemotherapy in patients with previously untreated DLBCL. It's divided into parts: early phases determine the best dose and schedule of odronextamab; later phase tests its efficacy against standard care rituximab.See study design
What are the potential side effects?
Potential side effects from taking odronextamab may include reactions related to infusion of the drug into your body, possible development of antibodies against the drug which could reduce its effectiveness or cause other side effects, impact on quality of life and daily activities.

Other Research
The most common treatments for Non-Hodgkin's Lymphoma (NHL) include monoclonal antibodies like rituximab and bispecific antibodies like odronextamab, often combined with chemotherapy. Rituximab targets the CD20 antigen on B-cells, leading to their destruction by the immune system. Odronextamab, a bispecific antibody, simultaneously binds to CD20 on B-cells and CD3 on T-cells, bringing them into close proximity to enhance the T-cells' ability to kill the B-cells. Chemotherapy works by targeting rapidly dividing cells, including cancer cells, to inhibit their growth and induce cell death. These mechanisms are vital for NHL patients as they provide multiple strategies to target and eliminate cancer cells, potentially improving treatment efficacy and patient outcomes.
