89Zr-DFO-REGN3767 PET Scan for Non-Hodgkin's Lymphoma
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests a new treatment called 89Zr-DFO-REGN3767 for individuals with non-Hodgkin's lymphoma, a cancer affecting the lymphatic system. Researchers aim to understand how the body processes this treatment and to determine the optimal dose and timing for PET scans, which visualize cancer in the body. The trial includes different groups receiving various doses to identify the most effective one. Suitable participants have non-Hodgkin's lymphoma with noticeable disease and good kidney function. As an Early Phase 1 trial, participants will be among the first to receive this treatment, aiding researchers in understanding its effects.
Do I have to stop taking my current medications for the trial?
The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
What prior data suggests that 89Zr-DFO-REGN3767 is safe for use in PET scans?
Research has shown that 89Zr-DFO-REGN3767 is under study for its use in PET scans to detect certain cancer cells. Earlier studies focused on safety found that this treatment did not cause any serious side effects, suggesting it is generally safe for humans.
In one initial study, 89Zr-DFO-REGN3767 spread well throughout the body, which is important for obtaining clear images. However, as this trial is in the early stages, the main goal is to understand how the body processes this treatment and to determine the right dosage. This means detailed safety information might still be limited.
Overall, existing studies suggest that this treatment is safe, but since the trial is in its early phase, more information is still being collected.12345Why are researchers excited about this trial?
Researchers are excited about 89Zr-DFO-REGN3767 for non-Hodgkin's lymphoma because it offers a new approach to tracking and understanding the disease. Unlike traditional treatments that focus on directly attacking cancer cells, this treatment involves a radiolabeled antibody that allows for precise imaging through PET scans. This enables doctors to visualize the distribution and activity of the drug within the body in real-time. By combining imaging with pharmacokinetics, researchers aim to gain insights into how the treatment interacts with lymphoma, potentially leading to more personalized and effective therapies.
What evidence suggests that 89Zr-DFO-REGN3767 could be effective for Non-Hodgkin's Lymphoma?
Research has shown that 89Zr-DFO-REGN3767 is under study for its potential to improve cancer imaging. This trial uses a special antibody that targets LAG-3, a protein linked to cancer growth. Participants will receive different doses of 89Zr-DFO-REGN3767. Studies have found that using this antibody in PET scans can help doctors see cancer cells more clearly. This clarity is important for understanding how well a tumor responds to treatment and making necessary adjustments. While promising evidence suggests it can enhance imaging, more research is needed to confirm its full effectiveness in treating non-Hodgkin's lymphoma.678910

Are You a Good Fit for This Trial?
This trial is for people with a type of cancer called Diffuse Large B Cell Lymphoma. They must have measurable disease, at least one lesion outside the liver, and good kidney function (eGFR >50 mL/min/1.73m2). It's not for those who've had severe side effects from immune therapies or haven't recovered from recent cancer treatments.Inclusion Criteria
