What is this trial about?

A plain-language summary of the goals, design and what participants do

This clinical trial is focused on studying a type of cancer called Follicular Lymphoma, which is a form of non-Hodgkin lymphoma. The study is specifically looking at cases where the disease has returned or has not responded to previous treatments, known as Relapsed/Refractory Follicular Lymphoma. The trial is testing a combination of two treatments: Zanubrutinib, also known by its code name BGB-3111, and Obinutuzumab. Zanubrutinib is a medication taken orally in capsule form and works by blocking a protein that helps cancer cells grow. Obinutuzumab is given through an infusion into a vein and is a type of antibody that targets cancer cells.

The purpose of this study is to compare the effectiveness of the combination of Zanubrutinib and Obinutuzumab against using Obinutuzumab alone. Participants in the study will be randomly assigned to receive either the combination treatment or Obinutuzumab by itself. The study will monitor how well the treatments work in reducing the cancer and how long the effects last. Participants will receive treatment for a period of up to 30 days, and their response to the treatment will be evaluated by independent experts.

Throughout the study, participants will have regular check-ups to monitor their health and any side effects from the treatments. The study aims to provide valuable information on whether the combination of Zanubrutinib and Obinutuzumab is more effective than Obinutuzumab alone in treating relapsed or refractory follicular lymphoma. This research could potentially lead to improved treatment options for patients with this type of cancer.

The research process

The trial runs in 7 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Joining the study

    Upon joining the study, the patient will be informed about the trial's purpose and procedures. The patient will provide written consent to participate, confirming understanding and agreement to comply with the study requirements.

  2. Step 2

    Initial assessment

    The patient will undergo an initial assessment to confirm eligibility. This includes a review of medical history, physical examination, and laboratory tests to ensure adequate organ function and the presence of measurable disease.

  3. Step 3

    Randomization

    The patient will be randomly assigned to one of two groups: one receiving obinutuzumab alone or the other receiving a combination of obinutuzumab and zanubrutinib.

  4. Step 4

    Treatment administration

    For patients receiving obinutuzumab alone, the medication will be administered intravenously. The specific dosage and frequency will be determined by the study protocol.

    For patients receiving the combination treatment, obinutuzumab will be administered intravenously, and zanubrutinib will be taken orally in capsule form. The dosage and frequency will be specified in the study protocol.

  5. Step 5

    Ongoing assessments

    Throughout the study, the patient will undergo regular assessments to monitor response to treatment. This includes physical exams, laboratory tests, and imaging studies to evaluate disease progression or response.

  6. Step 6

    Completion of treatment

    Upon completion of the treatment phase, the patient will undergo a final assessment to determine the overall response to the therapy. This will include a comprehensive review of all collected data.

  7. Step 7

    Follow-up

    After the treatment phase, the patient will enter a follow-up period. During this time, the patient will continue to be monitored for any long-term effects or recurrence of the disease.

Who can join the trial?

21 criteria

  • Must be at least 18 years old at the time of giving consent.
  • Must have proper organ function, which includes:
    • Enough white blood cells called neutrophils (more than 750 per cubic millimeter) without recent medical help to boost them.
    • Enough platelets (more than 50,000 per cubic millimeter) without recent medical help or transfusion.
    • Kidneys working well enough to clear at least 30 milliliters per minute, which can be measured in different ways.
    • Liver enzymes (AST and ALT) should not be more than 3 times the normal limit.
    • Total bilirubin in the blood should be less than 2 times the normal limit, unless you have a condition called Gilbert's syndrome.
    • Women who can have children must use very effective birth control methods before starting the study, during the study, and for at least 90 days after the last dose of one study drug or 18 months after the last dose of another, whichever is longer. These methods include:
      • Hormonal birth control that stops ovulation, like pills, patches, or injections.
      • Devices placed inside the uterus.
      • Surgical methods like blocking the fallopian tubes.
      • Having a partner who has had a vasectomy.
      • Choosing not to have sex, if it fits your lifestyle.
      • Men must agree to use barrier methods of birth control, like condoms, along with other methods during the study and for at least 90 days after the last dose of one study drug or 18 months after the last dose of another, whichever is longer.
      • Must be able to give written consent and understand what the study involves.
      • Must have a confirmed diagnosis of a type of cancer called B-cell follicular lymphoma, specifically grades 1, 2, or 3a.
      • Must have had at least two previous treatments for follicular lymphoma.
      • Must have previously received a specific type of treatment involving an anti-CD20 antibody and a combination of other drugs.
      • Must have experienced disease progression after the most recent treatment or have a disease that did not respond to the most recent treatment.
      • Must have measurable disease, meaning at least one lymph node larger than 2 centimeters or one area outside the lymph nodes larger than 1 centimeter.
      • Must have tissue samples available that confirm the diagnosis of B-cell follicular lymphoma, or a report confirming the diagnosis if tissue samples are not available.
      • Must have a performance status score of 0, 1, or 2, which indicates how well you can carry out daily activities.
      • Must have a life expectancy of at least 6 months.

Who cannot join the trial?

8 criteria

  • Patients who have a different type of cancer than Relapsed/Refractory Follicular Lymphoma cannot participate.

Investigated drugs

  • Zanubrutinib

    is a medication used in this trial to treat follicular lymphoma, a type of blood cancer. It works by blocking a specific protein in cancer cells, which helps to stop their growth and spread. In this study, zanubrutinib is combined with another medication to see if it improves treatment outcomes for patients whose cancer has returned or did not respond to previous treatments.

  • Obinutuzumab

    is another medication used in this trial. It is a type of antibody therapy that targets and attaches to a specific protein on the surface of cancer cells. This helps the immune system to recognize and destroy these cancer cells. In this study, obinutuzumab is used both alone and in combination with zanubrutinib to compare the effectiveness of the treatments.

What is already known about the treatment

  • Zanubrutinib

    This medication is administered orally and is currently being studied in clinical trials for its effectiveness in treating relapsed or refractory follicular lymphoma. It is a type of drug known as a Bruton’s tyrosine kinase (BTK) inhibitor, which works by blocking the BTK enzyme involved in the growth and survival of cancer cells. Zanubrutinib is classified as a targeted therapy, aiming to specifically interfere with cancer cell processes.

  • Obinutuzumab

    This medication is given through intravenous infusion and is used in the treatment of certain types of blood cancers, including relapsed or refractory follicular lymphoma. It is a monoclonal antibody that targets the CD20 protein on the surface of B-cells, leading to the destruction of these cancerous cells. Obinutuzumab is classified as an immunotherapy, which helps the immune system to fight cancer more effectively.

Investigated diseases

Relapsed/Refractory Follicular Lymphoma – This is a type of non-Hodgkin lymphoma that originates from B-cells, which are a type of white blood cell. It is characterized by the recurrence or persistence of the disease after initial treatment. The disease typically progresses slowly, but it can become more aggressive over time. Patients may experience symptoms such as enlarged lymph nodes, fatigue, and night sweats. The disease can affect various parts of the body, including the lymph nodes, bone marrow, and spleen. As it progresses, it may lead to complications due to the impaired function of the immune system.
