REGN5458 for Multiple Myeloma
(LINKER-MM1 Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores the safety and optimal dose of linvoseltamab (also known as REGN5458) for individuals with multiple myeloma, a type of blood cancer. Researchers aim to understand how linvoseltamab affects the body, including any side effects and its cancer-fighting capabilities. The trial includes different groups testing various doses and methods of administration. It suits those whose multiple myeloma has not responded to at least three different standard treatments, including certain drugs and therapies. As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new treatment.
Do I need to stop my current medications to join the trial?
The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that linvoseltamab, the treatment under study, was safe in earlier studies with patients who have relapsed or hard-to-treat multiple myeloma. These studies found that many patients responded well, with lasting improvements. While some side effects occurred, they were generally manageable. Importantly, few serious infections were reported, resulting in fewer severe problems for patients. Overall, the treatment appears well-tolerated, but this trial aims to learn more about the optimal dose and side effects.12345
Why do researchers think this study treatment might be promising for multiple myeloma?
Unlike the standard treatments for multiple myeloma, which often include combinations of chemotherapy, steroids, and other targeted therapies, Linvoseltamab is unique because it employs a novel approach. This investigational drug is a bispecific antibody that targets both BCMA (B-cell maturation antigen) on myeloma cells and CD3 on T-cells, essentially recruiting the body's immune system to directly attack the cancer cells. Additionally, researchers are exploring different delivery methods and dosages, including intravenous and subcutaneous options, which could offer more flexibility and potentially improve patient convenience and outcomes. This targeted action and innovative administration make Linvoseltamab a promising candidate that could change the treatment landscape for multiple myeloma.
What evidence suggests that linvoseltamab could be an effective treatment for multiple myeloma?
Research has shown that linvoseltamab, which participants in this trial may receive, may effectively treat multiple myeloma, a type of blood cancer. Studies have found that about 51% of patients responded positively to the treatment, with about half showing improvement. In one study, patients who received a 50 mg dose had a 48.1% response rate, with many experiencing significant improvement. Another study found even better results in patients with high-risk multiple myeloma, suggesting it could be particularly effective for them. Overall, linvoseltamab shows promising results for people with relapsed or difficult-to-treat multiple myeloma.12467

Are You a Good Fit for This Trial?
This trial is for adults with Multiple Myeloma who've tried at least three prior treatments, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 antibody but haven't seen improvement. They should be in relatively good health otherwise (ECOG ≤ 1). People can't join if they have certain other blood disorders or brain involvement of myeloma, severe heart issues, previous BCMA-targeted therapy except antibody-drug conjugates, or recent stem cell transplants.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- REGN5458
Trial Overview
The study tests REGN5458 as a solo treatment to see how safe it is and what dose works best (Phase 1), then checks its effectiveness against Multiple Myeloma that's resisted standard treatments (Phase 2). Researchers will also look into how the body processes the drug and any potential impact on quality of life.
