What is the purpose of this trial?

This trial tests Elranatamab as a follow-up treatment for individuals with high-risk multiple myeloma, a type of blood cancer. The primary goal is to determine how long patients can live without their cancer worsening after initial treatment with cilta-cel. It targets those whose myeloma grows outside the bones or have specific genetic risks and have already tried at least two other treatments. Participants should have completed cilta-cel treatment 3-6 months prior and not show signs of disease progression. As a Phase 2 trial, this study focuses on assessing the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications, but it does mention that you cannot use other anti-cancer agents or treatments while participating.

Is there any evidence suggesting that Elranatamab is likely to be safe for humans?

Research has shown that elranatamab, the treatment under study, is generally safe for people with multiple myeloma, a type of blood cancer. Studies have found that it leads to strong and lasting improvements in patients, with side effects that are usually mild and manageable with proper care. Previous research suggests that switching to a biweekly dosing schedule might enhance its long-term safety. Overall, elranatamab appears well-tolerated, offering hope for those with relapsed or hard-to-treat multiple myeloma. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising?

Elranatamab is unique because it offers a new approach to maintaining remission in multiple myeloma patients, especially those at high risk. Unlike traditional treatments like proteasome inhibitors or immunomodulatory drugs, Elranatamab is a bispecific antibody that targets both the BCMA protein on myeloma cells and CD3 on T-cells, effectively redirecting the immune system to attack the cancer cells. This dual-targeting mechanism could lead to more effective and sustained disease control. Researchers are excited about Elranatamab because it represents a promising advance in immunotherapy, with the potential to improve outcomes for patients who have already undergone other treatments.

What evidence suggests that Elranatamab might be an effective treatment for multiple myeloma?

Research has shown that Elranatamab yields promising results for patients with relapsed or hard-to-treat multiple myeloma. In one study, patients experienced an average of 17.2 months without disease progression, living over a year without worsening symptoms. Another study found that patients lived an average of 24.6 months, suggesting Elranatamab may extend survival. In this trial, Elranatamab will serve as maintenance therapy for patients with high-risk multiple myeloma who have received cilta-cel without evidence of disease progression. These findings suggest that Elranatamab could be an effective ongoing treatment for high-risk multiple myeloma following initial therapy. ^{3 4 6 7 8}

Are You a Good Fit for This Trial?

This trial is for patients with high-risk relapsed myeloma who have previously received cilta-cel and other treatments, including immunomodulatory drugs, proteasome inhibitors, and CD38 monoclonal antibodies. They must be in good enough health to participate in the study schedule, have adequate liver function and bone marrow function, and not be pregnant or breastfeeding. Those with severe kidney issues requiring dialysis or certain medical conditions like Guillain-Barre syndrome cannot join.

What Are the Treatments Tested in This Trial?

Interventions

• Elranatamab

Trial Overview The trial is testing Elranatamab's effectiveness following cilta-cel therapy in patients with high-risk relapsed myeloma. It aims to see how long these patients can live without their myeloma worsening after this treatment sequence. The focus is on those less responsive to cilta-cel due to specific risk factors such as extramedullary disease or particular genetic mutations.

How Is the Trial Designed?

Group I: Elranatamab Maintenance Therapy Experimental Treatment 1 Intervention

Patients who have received cilta-cel without evidence of disease progression and have clinical high-risk myeloma, will be treated with Elranatamab as maintenance therapy for a total of 12 months starting 3-6 months post cilta-cel infusion, at the FDA approved full dose.

Published Research Related to This Trial

Elranatamab, a bispecific antibody targeting BCMA and CD3, has shown promising results in treating relapsed refractory multiple myeloma, but its effectiveness in cases with central nervous system (CNS) involvement was previously unclear.

In a reported case, a 37-year-old male patient with CNS involvement of multiple myeloma was successfully treated with Elranatamab, suggesting potential for this therapy in challenging CNS-MM cases.

Elotuzumab is an FDA-approved monoclonal antibody for multiple myeloma that targets SLAMF7, a protein found on myeloma and natural killer cells, enhancing the immune response against cancer cells.

In clinical trials, elotuzumab showed strong efficacy and a good safety profile when used with other treatments like immunomodulatory drugs and proteasome inhibitors, making it a promising option for multiple myeloma patients.

Elranatamab is a bispecific T cell engager that targets BCMA on multiple myeloma cells, effectively activating T cells to kill these cancer cells, and has received its first approval in the USA for treating adult patients with relapsed or refractory multiple myeloma after at least four prior therapies.

The approval was based on the drug's response rate and durability of response, with ongoing studies required to confirm its clinical benefits, indicating a promising new option for patients with difficult-to-treat multiple myeloma.

In the phase 2 MagnetisMM-3 trial, elranatamab demonstrated a confirmed objective response rate of 61.0% in patients with relapsed or refractory multiple myeloma, indicating its efficacy as a treatment option.

The safety profile of elranatamab was manageable, with a reduction in grade 3-4 adverse events when switching from weekly to biweekly dosing, suggesting that this adjustment may enhance long-term safety without affecting treatment effectiveness.

Elotuzumab, when combined with other treatments, significantly improved progression-free survival (PFS) by 14% and overall survival (OS) by 20% in multiple myeloma patients, based on a review of five randomized control trials involving 1,763 participants.

While Elotuzumab showed efficacy in relapsed/refractory multiple myeloma, it also increased the risk of serious adverse events, infections, and cardiac disorders, indicating a need for careful monitoring in patients receiving this treatment.

In the MagnetisMM-1 trial involving 88 patients with relapsed or refractory multiple myeloma, elranatamab demonstrated a significant overall response rate of 63.6%, with 38.2% of patients achieving a complete response or better, indicating its efficacy even in heavily pre-treated patients.

Elranatamab showed manageable safety with no dose-limiting toxicities during dose escalation, although some patients experienced cytopenias and cytokine release syndrome; the median progression-free survival was 11.8 months and overall survival was 21.2 months, suggesting promising durability of responses.
