Study of Glofitamab, Atezolizumab, and Polatuzumab Vedotin for Adults with Relapsed or Refractory B-Cell Non-Hodgkin’s Lymphoma

2 1 1 1

What is this study about?

This clinical trial is focused on studying treatments for relapsed/refractory B-cell Non-Hodgkin’s Lymphoma, a type of cancer that affects the lymphatic system and has returned or not responded to previous treatments. The study involves several medications, including Glofitamab, Atezolizumab, Polatuzumab Vedotin, and a single pretreatment dose of Obinutuzumab. Additionally, a special imaging sub-study will use a tracer called 89Zr-Df-IAB22M2C to help visualize certain immune cells in the body.

The purpose of the study is to evaluate how effective these treatments are when used together in patients with this type of lymphoma. Participants will receive the medications through an intravenous infusion, which means the medicine is given directly into a vein. The study will also explore the best dose of Glofitamab when combined with Atezolizumab or Polatuzumab Vedotin. The study will take place over several years, with regular monitoring to assess how the body responds to the treatment and to check for any side effects.

Throughout the study, participants will undergo various tests, including imaging scans, to track the progress of the treatment. The imaging sub-study aims to see how well the tracer can show the presence of certain immune cells in the cancerous areas before and after treatment. This information will help researchers understand how the immune system interacts with the cancer and the treatment. The study is designed to gather important data that could lead to better treatment options for people with this type of lymphoma in the future.

1 initial treatment phase

The study begins with the administration of a single pretreatment dose of obinutuzumab. This is given as an intravenous infusion. The purpose of this dose is to prepare the body for subsequent treatments.

2 combination therapy phase

Following the pretreatment, the main treatment phase involves the administration of glofitamab in combination with either atezolizumab or polatuzumab vedotin. These medications are also given as intravenous infusions.

The specific combination and dosage will depend on the study group assigned. The frequency and duration of these infusions will be determined by the study protocol and monitored by the medical team.

3 imaging sub-study

Participants may undergo imaging studies using a tracer called 89Zr-Df-IAB22M2C. This tracer helps visualize the infiltration of certain immune cells in the tumor tissue.

These imaging procedures are conducted before and after treatment to assess the response of the immune system to the therapy.

4 monitoring and follow-up

Throughout the trial, regular monitoring of health status, including blood tests and imaging scans, is conducted to evaluate the effectiveness of the treatment and to identify any side effects.

The study aims to determine the best overall response rate and to monitor any adverse effects related to the treatment.

5 end of study

The study is expected to conclude by September 2026. At the end of the study, a final assessment will be conducted to evaluate the long-term effects and benefits of the treatment.

Who Can Join the Study?

Must have a type of cancer called relapsed/refractory B-cell Non-Hodgkin’s Lymphoma.

Trial locations

Glofitamab is a medication being studied for its effectiveness in treating certain types of B-cell non-Hodgkin’s lymphoma. It is used in combination with other treatments to help the immune system target and destroy cancer cells.

Atezolizumab is an immunotherapy drug that helps the body’s immune system attack cancer cells. It is being tested in combination with other medications to see if it can improve treatment outcomes for patients with relapsed or refractory B-cell non-Hodgkin’s lymphoma.

Polatuzumab Vedotin is a type of targeted therapy that combines an antibody with a chemotherapy drug. It is designed to specifically target and kill cancer cells while minimizing damage to normal cells. This medication is being studied in combination with other treatments for its potential to improve outcomes in patients with certain types of lymphoma.

Obinutuzumab is an antibody therapy that targets specific proteins on the surface of cancer cells. It is used as a pretreatment to help enhance the effectiveness of other cancer therapies in the study.

Non-Hodgkin’s Lymphoma – This is a type of cancer that originates in the lymphatic system, which is part of the body’s immune system. It involves the abnormal growth of lymphocytes, a type of white blood cell, which can form tumors throughout the body. The disease can be classified into various subtypes, including B-cell lymphomas, which are the most common. It can progress at different rates, with some forms being aggressive and others more indolent. Symptoms may include swollen lymph nodes, fever, night sweats, and weight loss. The progression of the disease can vary widely depending on the specific subtype and other individual factors.
