What is the purpose of this trial?

This trial tests a new treatment for people with multiple myeloma, a type of blood cancer. The goal is to determine if a special type of modified immune cell, called CAR T cells, is safe. Some participants might also take a drug called Lenalidomide (Revlimid) to see if it enhances the treatment's effectiveness. The trial seeks individuals whose multiple myeloma has returned or not improved after at least two different treatments, including those targeting the immune system. 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 need to stop taking your current medications. However, you cannot be on systemic steroids (except for adrenal replacement) within two weeks of cell collection.

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

Research shows that anti-BCMA CAR T-cell therapy is generally safe for patients with multiple myeloma. Studies found that serious side effects, such as cytokine release syndrome (CRS), occurred but resolved quickly, often within 24 hours. Many patients tolerated the treatment well.

Research suggests that adding lenalidomide to CAR T-cell therapy keeps the combination effective and manageable. While some side effects occur, they are usually controllable and short-lived.

Since this study is in an early phase, the main goal is to ensure the treatment's safety for people. This phase involves closely monitoring how the body reacts to the new therapy. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about using EGFRt/BCMA-41BBz CAR T cells for multiple myeloma because this approach offers a novel and potentially more targeted way to attack cancer cells. Unlike standard treatments like chemotherapy and monoclonal antibodies, which can affect both healthy and cancerous cells, CAR T cells are engineered to specifically recognize and eliminate multiple myeloma cells by targeting the BCMA protein found on their surface. This precision can lead to more effective treatment with fewer side effects. Additionally, the potential combination with lenalidomide, an immune-modulating drug, might enhance the effectiveness of CAR T cells, potentially leading to better outcomes for patients.

What evidence suggests that this trial's treatments could be effective for multiple myeloma?

Research shows that a new treatment called EGFRt/BCMA-41BBz CAR T cell therapy could be promising for multiple myeloma. Studies found that 92% of patients experienced a reduction or disappearance of their cancer. Additionally, 68% of patients had a very good partial response or better, indicating strong treatment effects. In this trial, some participants will receive the CAR T cell therapy alone, while others will receive it with lenalidomide. Specifically, when combined with lenalidomide, patients lived an average of 18.3 months without their cancer worsening. These results suggest that this CAR T cell therapy could effectively treat multiple myeloma. ^{2 3 4 6 7}

In a phase I clinical trial involving 30 multiple myeloma patients, anti-BCMA CAR T cells showed favorable safety with no high-grade cytokine release syndrome and only one case of low-grade neurologic toxicity.

The treatment demonstrated significant efficacy, with 10 out of 15 patients with measurable disease achieving a partial response or better, and 4 patients converting to minimal residual disease-negative complete response, indicating strong antimyeloma activity.

In a phase II trial involving 69 patients with relapsed or refractory multiple myeloma, the combination of anti-BCMA and anti-CD19 CAR T cells resulted in a high overall response rate of 92%, with 60% achieving a complete response.

The treatment demonstrated a median progression-free survival of 18.3 months and a manageable safety profile, although 95% of patients experienced cytokine release syndrome, indicating the need for monitoring during treatment.
