What is the purpose of this trial?

This trial examines whether iberdomide, a new drug, can extend the lives of people with multiple myeloma after receiving a specific CAR-T cell therapy called idecabtagene vicleucel (also known as Abecma or ide-cel). Typically, after this CAR-T therapy, patients undergo monitoring without additional treatment. Iberdomide may enhance the immune system's T-cells and control the cancer longer than monitoring alone. Individuals with stabilized multiple myeloma after idecabtagene vicleucel and multiple prior treatments might be suitable for this trial. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

Will I have to stop taking my current medications?

The trial does not specify if you must stop all current medications, but you may need to switch from strong CYP3A4 inducers or inhibitors to a different medication and wait for a washout period (time without taking certain medications) before starting the trial.

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

Research has shown that iberdomide has been generally safe in past studies. In one study, when combined with other treatments like dexamethasone, most participants did not experience serious problems. Another study found that when iberdomide was paired with different drugs, the side effects were known and manageable.

Although iberdomide remains under investigation, these results are encouraging. They suggest it could be safe for individuals with multiple myeloma, a type of blood cancer. However, since this trial is in phase 2, researchers continue to closely monitor its safety and effectiveness. If considering joining a trial, discussing it with a healthcare provider is always advisable. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for multiple myeloma?

Most treatments for multiple myeloma focus on controlling the disease with chemotherapy, immunomodulatory drugs, or proteasome inhibitors. But iberdomide stands out because it is a novel cereblon E3 ligase modulator, which offers a unique mechanism of action by enhancing the body's immune response against cancer cells. Researchers are excited about iberdomide because it can potentially improve the effectiveness of existing therapies by targeting multiple pathways in cancer cells, possibly leading to better patient outcomes. Additionally, its oral administration makes it a more convenient option compared to some traditional treatments that require intravenous infusions.

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

Research shows that iberdomide, which participants in this trial may receive, is a promising treatment for multiple myeloma, a type of blood cancer. Studies have found that it improves patient response to treatment when combined with other medicines. For instance, one study reported a 93.1% overall response rate when iberdomide was used with daratumumab and dexamethasone. Iberdomide activates immune cells called T-cells, which help fight cancer cells. This action might make it effective in controlling multiple myeloma for longer periods, especially after treatments like CAR-T therapy. Overall, iberdomide has demonstrated significant effectiveness in various situations involving multiple myeloma. ^{1 5 6 7 8}

Are You a Good Fit for This Trial?

This trial is for adults over 18 with multiple myeloma who've had CAR-T therapy (idecabtagene vicleucel) within the past 80-110 days. They should be in stable condition or better and haven't taken any other myeloma treatments since, except possibly short steroids for CAR-T side effects. People can't join if they're resistant to Iberdomide or have had certain recent therapies.

What Are the Treatments Tested in This Trial?

Interventions

• Iberdomide
• Idecabtagene Vicleucel

Trial Overview The study compares maintenance therapy using a drug called Iberdomide against just monitoring the disease after CAR-T treatment for multiple myeloma. The goal is to see if Iberdomide helps patients live longer by keeping cancer under control better than no further treatment.

How Is the Trial Designed?

Group I: Group II (iberdomide) Experimental Treatment 8 Interventions

Patients receive iberdomide PO QD on days 1-21 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients also undergo bone marrow aspiration and biopsy throughout the trial, undergo collection of blood samples at screening and on study, and undergo PET/CT and/or skeletal survey x-ray, CT, or MRI at screening and then as clinically indicated.

Group II: Group 1 (monitoring) Active Control 8 Interventions

Patients undergo disease monitoring at monthly clinic visits until disease progression. Patients also undergo bone marrow aspiration and biopsy throughout the trial, undergo collection of blood samples at screening and on study, and undergo PET/CT and/or skeletal survey x-ray, CT, or MRI at screening and then as clinically indicated.

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 phase 3 trial with 386 patients suffering from relapsed and refractory multiple myeloma, idecabtagene vicleucel (ide-cel) significantly improved progression-free survival (13.3 months) compared to standard treatments (4.4 months), indicating its efficacy in this challenging patient population.

The treatment with ide-cel resulted in a 71% overall response rate, including a 39% complete response rate, although it was associated with high rates of adverse events (93% grade 3 or 4), including cytokine release syndrome in 88% of patients.

In a phase 3 trial involving 559 patients with relapsed or refractory multiple myeloma who had previously received lenalidomide, the combination of pomalidomide, bortezomib, and dexamethasone significantly improved progression-free survival compared to bortezomib and dexamethasone alone, with a median survival of 11.20 months versus 7.10 months.

While the combination treatment showed better efficacy, it also resulted in higher rates of serious adverse events, particularly neutropenia and infections, indicating that while effective, careful monitoring for side effects is necessary.

In a phase I/II study involving 29 patients with lenalidomide and proteasome inhibitor-refractory multiple myeloma, the combination of ixazomib, pomalidomide, and dexamethasone showed a promising overall response rate of 51.7% and a median duration of response of 16.8 months.

The treatment was generally well-tolerated, with common side effects aligning with those expected from the individual drugs, suggesting that this all-oral regimen warrants further investigation in relapsed/refractory multiple myeloma.

Bortezomib, both alone and in combination with other treatments, has demonstrated high response rates and manageable side effects in patients with relapsed or refractory multiple myeloma, indicating its efficacy and safety.

Ongoing trials of bortezomib combined with lenalidomide and dexamethasone are expected to provide important insights into its potential as a foundational treatment for advanced multiple myeloma.
