What You Need to Know Before You Apply

What is the purpose of this trial?

This trial is testing Elranatamab, a drug that helps the immune system target and kill cancer cells, in patients with a type of blood cancer that hasn't responded to other treatments. The drug works by connecting immune cells to cancer cells so they can be destroyed.

Do I need to stop my current medications for the trial?

The trial information does not specify if you need to stop taking your current medications. However, it mentions that you should not have taken an investigational drug within 30 days before starting the trial.

Is Elranatamab safe for humans?

In a clinical trial for multiple myeloma, Elranatamab was found to have manageable safety with no dose-limiting toxicities observed. Some patients experienced side effects like low blood cell counts (cytopenias) and a reaction called cytokine release syndrome, but these were considered manageable. ^{1 2 3 4 5}

What makes the drug Elranatamab unique for treating multiple myeloma?

Elranatamab is unique because it is a bispecific antibody that targets both BCMA on myeloma cells and CD3 on T cells, activating the T cells to attack the cancer cells. It is administered subcutaneously and has shown promising results in patients who have already undergone multiple other treatments, including those who have had prior BCMA-directed therapy. ^{1 2 5 6 7}

What data supports the effectiveness of the drug Elranatamab for treating multiple myeloma?

Elranatamab has shown promising results in treating multiple myeloma, with a study reporting a 63.6% response rate and 38.2% of patients achieving complete response or better. The drug was effective even in patients who had received prior treatments, with a median duration of response of 17.1 months and manageable safety profile. ^{1 2 5 8 9}

Are You a Good Fit for This Trial?

This trial is for adults with multiple myeloma who haven't responded to at least one proteasome inhibitor (PI), one immunomodulatory drug (IMiD), and one anti-CD38 antibody. Participants should have measurable disease, be in stable condition, not pregnant, willing to use contraception, and without other active cancers or serious infections. There are two groups: those who've had BCMA-targeted therapy before and those who haven't.

Inclusion Criteria

Not pregnant and willing to use contraception

I have been diagnosed with multiple myeloma.

Any side effects from my previous treatments have mostly gone away.

Exclusion Criteria

Previous administration with an investigational drug within 30 days or 5 half-lives preceding the first dose of study intervention used in this study (whichever is longer)

I had a stem cell transplant less than 3 months ago.

I have been diagnosed with amyloidosis.

What Are the Treatments Tested in This Trial?

Interventions

• Elranatamab (PF-06863135)

Trial Overview The study tests Elranatamab as a single treatment for relapsed/refractory multiple myeloma. It's a bispecific antibody that directs the body's T-cells to attack the cancer cells by recognizing both T-cell markers (CD3) and myeloma cell markers (BCMA). The goal is to see if this targeted approach can help control the disease.

How Is the Trial Designed?

Group I: Elranatamab (cohort B) Experimental Treatment 1 Intervention

BCMA-CD3 bispecific antibody

Group II: Elranatamab (cohort A) Experimental Treatment 1 Intervention

BCMA-CD3 bispecific antibody

Published Research Related to This Trial

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.

Elranatamab: First Approval. Dhillon, S.[2023]

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.

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.

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.

In a phase 3 study involving 646 patients with relapsed or refractory multiple myeloma, the combination of elotuzumab, lenalidomide, and dexamethasone significantly improved progression-free survival, with a median of 19.4 months compared to 14.9 months for the control group.

The overall response rate was also higher in the elotuzumab group at 79% versus 66% in the control group, indicating that elotuzumab enhances the effectiveness of standard treatment for this condition.

Elotuzumab, when combined with lenalidomide and dexamethasone, significantly improves progression-free survival (PFS) in patients with relapsed or refractory multiple myeloma, with a median PFS of 19.4 months compared to 14.9 months for the standard treatment.

The treatment showed a higher overall response rate (ORR) of 75.8% versus 65.5% for the standard therapy, although serious adverse reactions were more common in the elotuzumab group (65% vs. 57%).

In a review of 20 studies involving 2220 patients with relapsed/refractory multiple myeloma, carfilzomib combinations showed a high overall response rate of 61%, with 29% achieving at least a very good partial response.

Elotuzumab combinations were particularly effective, with a 73% overall response rate and 37% achieving at least a very good partial response, although patients experienced significant nonhematologic adverse events like cardiac issues and pneumonia.

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 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.
