What is the purpose of this trial?

This trial aims to determine if the quality of T cells used in the treatment ide-cel (a type of CAR T-cell therapy) affects its ability to prevent the return of multiple myeloma, a type of blood cancer. It targets patients whose cancer has returned or resisted treatment after a stem cell transplant. One group will have received their own stem cells, while the other will have received donor stem cells. Ideal participants have undergone multiple treatments and a stem cell transplant but still experience cancer symptoms. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

The trial requires that you stop taking any systemic anti-myeloma therapy 14 days before leukapheresis (a procedure to collect blood cells), and you must taper off steroids 72 hours before leukapheresis and lymphodepletion (a process to reduce white blood cells). Other medications may be allowed, but it's best to discuss your specific situation with the trial team.

Is there any evidence suggesting that ide-cel (bb2121) is likely to be safe for humans?

Studies have shown that ide-cel (also known as bb2121) is generally well-tolerated in people with relapsed or refractory multiple myeloma. Research indicates that while some side effects occur, they are often manageable. For example, one study found that ide-cel treatment led to strong and lasting improvements in patients. However, like many cancer treatments, side effects can occur. The most common include low blood cell counts and infections, but these are usually expected and treatable. Overall, the treatment has shown promise in terms of safety and effectiveness. ^{1 2 3 4 5}

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

Researchers are excited about Ide-cel (bb2121) for multiple myeloma because it uses a cutting-edge approach known as CAR-T cell therapy. Unlike traditional treatments like chemotherapy and proteasome inhibitors, which attack cancer cells broadly, Ide-cel reprograms a patient's own immune cells to specifically target and destroy myeloma cells. This personalized approach has the potential to offer more targeted and effective treatment for patients who have relapsed or not responded to other therapies. Additionally, there are two distinct delivery methods being explored: one involves using the patient's own stem cells in an autologous transplant, and the other uses healthy donor stem cells in an allogeneic transplant, offering more options depending on individual patient situations.

What evidence suggests that ide-cel (bb2121) might be an effective treatment for multiple myeloma?

Research has shown that ide-cel (bb2121) holds great promise for treating relapsed or refractory multiple myeloma. In one study, 89% of patients responded well, with their cancer shrinking or disappearing. Another study demonstrated an 84% response rate, with over half of the patients experiencing a very deep remission, where the cancer was almost completely gone. These studies suggest that ide-cel can lead to significant and lasting improvements for many patients. In this trial, participants will be divided into two cohorts: one for those who had an autologous hematopoietic stem cell transplant (AHCT) and another for those who had an allogeneic hematopoietic cell transplant (alloHCT). The treatment uses modified T cells, a type of white blood cell, to find and destroy cancer cells. ^{1 3 4 6 7}

Exclusion Criteria

You had certain medical procedures or conditions within a specific time frame, have certain medical conditions, are taking certain medications, or have certain infections, which would prevent you from taking part in the study.

What Are the Treatments Tested in This Trial?

Interventions

• Ide-cel (bb2121)

Trial Overview

The study tests if T cells used to create the drug ide-cel (bb2121) can prevent cancer recurrence in patients with relapsed/refractory multiple myeloma post-cell transplant. It examines the quality of T cells' impact on ide-cel's effectiveness.

How Is the Trial Designed?

Group I: Cohort 2 Experimental Treatment 1 Intervention

Participants with relapsed/refractory MM who had an allogeneic hematopoietic cell transplant (alloHCT). In an alloHCT, a person's stem cells are replaced with new, healthy stem cells from a donor.

Group II: Cohort 1 Experimental Treatment 1 Intervention

Participants with relapsed/refractory MM who had an autologous hematopoietic stem cell transplant (AHCT). In an AHCT, their own blood-forming stem cells are collected. Participants are then treated with high doses of chemotherapy which kills the cancer cells, but it also gets rid of the blood-producing cells that are left in the bone marrow. Afterward, the collected stem cells are put back into the bloodstream, allowing the bone marrow to produce new blood cells.

Idecabtagene vicleucel (ide-cel) is a safe and effective CAR T cell therapy for relapsed/refractory multiple myeloma, showing low rates of severe side effects (6.5% cytokine release syndrome and 1.6% neurotoxicity) in a study of 62 patients with an 18.1-month follow-up.

The therapy achieved a high overall response rate of 75.8%, with 38.7% of patients reaching complete response, and the study identified specific T cell characteristics that correlate with longer-lasting responses, suggesting potential for optimizing treatment outcomes.

Idecabtagene vicleucel (ide-cel) significantly improved overall response rates in patients with triple-class exposed relapsed and refractory multiple myeloma, showing an odds ratio of 5.30 compared to conventional care.

Patients treated with ide-cel also experienced better progression-free survival and overall survival, with hazard ratios of 0.50 and 0.37, respectively, indicating a substantial benefit over conventional treatment options.

In a study of 78 patients treated with idecabtagene vicleucel (ide-cel) for relapsed and refractory multiple myeloma, 14.1% experienced cardiac events, including heart failure and atrial fibrillation, indicating a notable safety concern associated with this CAR-T therapy.

Higher-grade cytokine release syndrome and poor baseline performance status were linked to an increased risk of cardiac events, which in turn were associated with worse overall survival and progression-free survival, suggesting that monitoring for cardiac complications is important in patients receiving ide-cel.

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.

Idecabtagene vicleucel (ide-cel) is an effective CAR T cell therapy for heavily pretreated relapsed and refractory multiple myeloma, showing higher response rates with increased exposure levels in a study of 127 patients.

The analysis identified specific factors, such as female sex and lower baseline serum monoclonal protein levels, that predict better treatment responses, while also establishing a positive benefit-risk profile for ide-cel doses ranging from 150 to 450 million CAR+ T cells.

In a phase 2 study involving 140 patients with relapsed and refractory multiple myeloma, idecabtagene vicleucel (ide-cel) demonstrated a 73% overall response rate, with 33% achieving a complete response or better after treatment.

While ide-cel showed significant efficacy, it also resulted in high rates of toxic effects, including severe neutropenia (91%) and cytokine release syndrome (84%), highlighting the need for careful monitoring during treatment.
