What is the purpose of this trial?

This trial explores a new treatment for individuals with multiple myeloma, a type of blood cancer, who have already tried several other treatments. It tests the combination of three drugs—Elotuzumab, Iberdomide (a potential new drug), and Dexamethasone—to assess their effectiveness when used together after a specific previous treatment called Idecabtagene Vicleucel. The trial seeks participants who have had multiple myeloma for some time and have tried at least four different treatments, including Ide-cel. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive this new therapy.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications. However, you cannot have certain treatments like strong CYP3A inducers or inhibitors within 14 days before starting the trial, and you should not have had certain other therapies within specific time frames before the trial begins.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research shows that the combination of Iberdomide, Elotuzumab, and Dexamethasone is generally safe and manageable for patients with relapsed or refractory multiple myeloma. Previous studies found that patients tolerate these treatments well when used together. So far, no major safety issues have been reported, though some side effects may occur, as with all treatments. These studies are ongoing, and researchers continue to monitor for any negative effects. Since this trial is in its early stages, it focuses on finding the safest dose, making safety a top priority. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about Iberdomide, especially when combined with Elotuzumab and Dexamethasone, because it offers a novel approach to treating multiple myeloma. Unlike some existing treatments, Iberdomide is a new type of immunomodulatory drug (IMiD) that can stimulate the immune system more effectively to target cancer cells. This unique mechanism of action potentially increases the body's ability to fight the disease while possibly reducing some of the side effects associated with traditional therapies. Additionally, the combination of these drugs aims to enhance overall treatment efficacy by tackling the cancer from multiple angles, which could lead to better outcomes for patients.

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

Research shows that the combination of Iberdomide, Elotuzumab, and Dexamethasone can help treat multiple myeloma, especially in patients who have tried other treatments. In this trial, participants will receive this combination therapy. Studies have found that Iberdomide, when used with Dexamethasone, produces promising results in patients who have undergone several previous treatments. Elotuzumab activates the body's immune cells to attack cancer cells. This combination therapy enhances the immune system's ability to target and fight multiple myeloma. Early findings suggest that this treatment can be a good option for those with relapsed or difficult-to-treat multiple myeloma. ^{1 6 7 8 9}

Published Research Related to This Trial

In a phase 2 study involving 152 patients with relapsed/refractory multiple myeloma, the combination of elotuzumab with bortezomib and dexamethasone (EBd) resulted in a longer progression-free survival (PFS) of 9.7 months compared to 6.9 months with bortezomib and dexamethasone alone (Bd).

The addition of elotuzumab did not increase clinically significant adverse events, indicating that it can provide clinical benefits without added toxicity, and it showed a promising overall response rate of 66% compared to 63% for Bd.

Randomized phase 2 study: elotuzumab plus bortezomib/dexamethasone vs bortezomib/dexamethasone for relapsed/refractory MM. Jakubowiak, A., Offidani, M., Pégourie, B., et al.[2022]

Iberdomide combined with dexamethasone demonstrated meaningful clinical activity in heavily pretreated patients with relapsed or refractory multiple myeloma, achieving an overall response rate of 32% in the dose-escalation cohort and 26% in the dose-expansion cohort, indicating its potential effectiveness even in difficult-to-treat cases.

The treatment was generally safe, with a recommended phase 2 dose established at 1.6 mg, although some patients experienced serious adverse events, including neutropenia and infections, highlighting the need for careful monitoring during treatment.

In a study of 117 patients with relapsed or refractory multiple myeloma, those treated with elotuzumab plus pomalidomide and dexamethasone experienced a median progression-free survival of 10.3 months, compared to 4.7 months for those receiving pomalidomide and dexamethasone alone, indicating a significant improvement in treatment efficacy.

The overall response rate was also higher in the elotuzumab group at 53% versus 26% in the control group, with fewer severe adverse events like neutropenia and anemia, suggesting that elotuzumab may enhance treatment outcomes while maintaining a manageable safety profile.

In a study of 22 patients with relapsed or refractory multiple myeloma, the combination of bortezomib and dexamethasone (BD therapy) resulted in a high response rate, with 77.3% achieving at least a partial response, indicating its efficacy.

Switching to a once-weekly administration of bortezomib after initial twice-weekly treatment significantly reduced severe gastrointestinal side effects while maintaining the therapy's effectiveness, suggesting a safer dosing strategy.

In the phase II ELOQUENT-3 trial, the combination of elotuzumab with pomalidomide and dexamethasone (EPd) significantly improved overall survival (OS) in patients with relapsed/refractory multiple myeloma, with a median OS of 29.8 months compared to 17.4 months for the pomalidomide/dexamethasone (Pd) group.

The safety profile of EPd was consistent with previous studies, showing no new safety concerns, indicating that this treatment is both effective and safe for patients who have already undergone multiple lines of therapy.

Elotuzumab, a humanized monoclonal antibody targeting SLAMF7, has been shown to enhance the effectiveness of treatments for relapsed and/or refractory multiple myeloma when combined with lenalidomide/dexamethasone or pomalidomide/dexamethasone, leading to FDA approval for these combinations.

The use of elotuzumab stimulates natural killer cells to attack multiple myeloma cells, offering a promising mechanism of action that could improve treatment outcomes without significantly increasing toxicity.

Elotuzumab, a monoclonal antibody targeting the SLAMF7 receptor, shows significant antimyeloma activity when combined with other treatments like bortezomib or lenalidomide, improving patient responses without adding extra toxicity.

Approved by the FDA in 2015 for patients with relapsed or refractory multiple myeloma after 1-3 prior therapies, elotuzumab has demonstrated efficacy in clinical trials, particularly in combination therapies, while showing a favorable safety profile.

Ibrutinib, a novel oral treatment for multiple myeloma, showed a clinical benefit rate of 28% when combined with low-dose dexamethasone in patients who had undergone a median of 4 prior therapies, indicating its potential effectiveness in relapsed/refractory cases.

The study reported manageable safety profiles, with grade 3-4 adverse events occurring in a minority of patients, suggesting that ibrutinib could be a tolerable option for patients with multiple myeloma who have limited treatment options.

In a study of 23 patients with relapsed or refractory multiple myeloma, both low (1.0 mg/m2) and standard (1.3 mg/m2) doses of bortezomib combined with dexamethasone showed similar response rates, with 70% for the low dose and 61.5% for the standard dose, indicating that lower doses can be just as effective.

However, the standard dose of 1.3 mg/m2 was associated with more adverse effects, including serious infections and treatment-related deaths, suggesting that while it may be more effective, it also carries a higher risk of toxicity.
