Diffuse Large B Cell Lymphoma study: Glofitamab
Official title Feasibility Trial of Glofitamab in a Response Adapted Approach Incorporating Interim FDG PET and ctDNA to Optimize Primary Therapy of DLBCL (GRAIL)
ClinicalTrials.gov ID: NCT06050694
What this study is testing
What is glofitamab?
Glofitamab is an investigational medicine being studied as a potential treatment for diffuse large B cell lymphoma (DLBCL). is designed to bind to specific proteins on the surface of cancer cells and immune cells to help the body's immune system attack the cancer.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- This study aims to see if using scans and blood tests can help doctors choose the best treatment plan for this type of lymphoma.
- Who it's for
- The study is looking for adults who have been diagnosed with diffuse large B-cell lymphoma but have not started treatment yet.
- What's involved
- Participants will receive the drug glofitamab and undergo specific scans and blood tests to check how the disease is responding.
- Time commitment
- The source text does not specify the total duration or the number of visits required.
- Phase 2: a mid-size study of how well it works
- Which group you join is decided by chance.
