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 Relapsed or Refractory Aggressive B-cell Non-Hodgkin Lymphoma. The study will explore the effects of a medication called MEN1703, both on its own and in combination with another medication named Glofitamab. MEN1703 is available in capsule form, while Glofitamab is administered as a solution for infusion, which means it is given directly into the bloodstream through a vein. The purpose of the study is to evaluate the safety and effectiveness of these treatments in patients who have not responded to previous therapies or whose cancer has returned.

The study will be conducted in different parts. Initially, the safety and tolerability of MEN1703 alone and in combination with Glofitamab will be assessed. This means researchers will monitor how well patients tolerate the medications and any side effects that may occur. Following this, the study will focus on the ability of these treatments to fight the lymphoma, which is a type of cancer that affects the lymphatic system, a part of the body's immune system. The study will involve regular monitoring and assessments to track the progress and response of the cancer to the treatments.

Participants in the study will receive either the combination of MEN1703 and Glofitamab or MEN1703 alone. Some participants may also receive a placebo, which is a substance with no active medication, to help compare the effects of the treatments. The study aims to provide valuable information on the potential benefits and risks of these treatments for patients with this challenging form of lymphoma. The trial is expected to continue until the end of 2026, with recruitment starting in late 2024.

The research process

The trial runs in 5 steps – from screening to follow-up. Each step says what happens and what the team monitors.

  1. Step 1

    Initial assessment

    Upon joining the study, an initial assessment is conducted to confirm eligibility. This includes reviewing medical history and current health status.

    A series of tests and evaluations are performed to ensure all criteria are met, such as blood tests and imaging scans.

  2. Step 2

    Group assignment

    Participants are assigned to one of two groups. Group 1 receives a combination of MEN1703 and glofitamab, while Group 2 receives MEN1703 alone.

    The assignment is based on specific criteria and study requirements.

  3. Step 3

    Treatment initiation

    Treatment begins with the administration of the assigned medication. MEN1703 is taken orally in capsule form, with dosages of 100 mg and 25 mg.

    For Group 1, glofitamab is administered through an intravenous infusion. The dosage and frequency are determined by the study protocol.

  4. Step 4

    Monitoring and follow-up

    Regular monitoring is conducted to assess the safety and effectiveness of the treatment. This includes routine blood tests and health evaluations.

    Participants attend scheduled follow-up visits to track progress and address any side effects or concerns.

  5. Step 5

    Completion of treatment

    Upon completion of the treatment phase, a final assessment is conducted to evaluate the overall response to the medication.

    Participants may be asked to provide feedback on their experience and any changes in their health condition.

Investigated drugs

  • MEN1703

    is a medication being tested in this clinical trial. It is being studied both on its own and in combination with another medication. The main goal of using MEN1703 is to see how well it works against a type of cancer called aggressive B-cell non-Hodgkin lymphoma, which is a cancer of the lymphatic system. Researchers are also looking at how safe and tolerable MEN1703 is for patients, meaning they want to know if it causes any side effects and how patients feel while taking it.

  • Glofitamab

    is another medication involved in this trial. It is used in combination with MEN1703 to see if the two medications together can better fight the aggressive B-cell non-Hodgkin lymphoma. Glofitamab is designed to help the body's immune system target and destroy cancer cells. The trial aims to understand how effective this combination is in treating the cancer and to ensure that it is safe for patients to use.

What is already known about the treatment

MEN1703 – MEN1703 is a medication currently being studied in a clinical trial for its use in treating patients with relapsed or refractory aggressive B-cell Non-Hodgkin Lymphoma. It is administered as a monotherapy or in combination with another drug called glofitamab. The main goal of the trial is to assess the safety and effectiveness of MEN1703 in reducing lymphoma symptoms. MEN1703 works at the molecular level by targeting specific pathways in cancer cells to inhibit their growth and survival. It is classified as an investigational drug, meaning it is still under research and not yet approved for general medical use.

Investigated diseases

Relapsed or Refractory Aggressive B-cell Non-Hodgkin Lymphoma – This is a type of cancer that originates in the lymphatic system, specifically affecting B-cells, which are a type of white blood cell. It is characterized by the rapid growth of malignant cells in the lymph nodes, spleen, or other organs. The disease is termed "relapsed" when it returns after treatment and "refractory" when it does not respond to standard treatments. As the disease progresses, it can lead to symptoms such as swollen lymph nodes, fever, night sweats, and weight loss. The aggressive nature of this lymphoma means it can spread quickly to other parts of the body. The progression of the disease can vary, with some cases advancing rapidly while others may progress more slowly.
