What is the purpose of this trial?

This trial explores a new approach to treating multiple myeloma, a type of blood cancer that often recurs after treatment. The researchers are testing the safety of using a drug called talquetamab before administering a CAR T-cell therapy known as cilta-cel (ciltacabtagene autoleucel). This trial targets individuals who have tried other treatments for multiple myeloma but continue to experience the disease. Those with multiple myeloma that has not responded well to past treatments and affects daily life might find this trial suitable. 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.

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

The trial requires that you stop certain treatments before joining. Specifically, you must not have had certain therapies like high-dose chemotherapy, specific antibodies, or radiation therapy within a specified time before enrollment. However, the protocol does not specify all medications, so it's best to discuss your current medications with the trial team.

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

A previous study found talquetamab to be well-tolerated by patients with relapsed or refractory multiple myeloma. The most common side effects, such as skin rash and changes in taste, were manageable. Research has shown that ciltacabtagene autoleucel, also known as cilta-cel, received approval in 2022 for similar conditions, indicating a strong safety profile. These treatments have been studied for their safety and have shown promising results. Although this trial is in an early phase, the data so far supports their use in people with this type of cancer. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about Talquetamab and Ciltacabtagene autoleucel for multiple myeloma because they represent a novel approach to treatment. Unlike traditional therapies such as chemotherapy, these treatments involve leveraging the body's own immune system. Talquetamab works as a bridging therapy and targets a specific protein on myeloma cells, which is different from the broader attack seen with standard chemotherapy. Ciltacabtagene autoleucel is a CAR T-cell therapy, which means it involves modifying a patient's T-cells to better recognize and destroy cancer cells. This combination offers a targeted and potentially more effective way to treat relapsed or refractory multiple myeloma.

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

Research has shown that talquetamab is effective for patients with multiple myeloma who have tried several other treatments. Talquetamab targets specific proteins on cancer cells, aiding the immune system in fighting the disease. In this trial, participants will receive talquetamab as a bridging therapy during CAR T-cell manufacturing, followed by Ciltacabtagene autoleucel (a type of CAR T-cell therapy). Studies indicate that using talquetamab before Ciltacabtagene autoleucel may help control the cancer in the short term. Talquetamab has been approved for use when the cancer returns or does not respond to other treatments, highlighting its effectiveness for these patients. This combination approach aims to enhance the immune system's ability to attack and control the cancer. ^{1 3 4 6 7}

Are You a Good Fit for This Trial?

This trial is for patients with relapsed and refractory multiple myeloma, meaning their cancer has returned or didn't respond to treatment. Specific eligibility details are not provided, but typically participants must meet certain health standards and have a history of the condition being studied.

Inclusion Criteria

Have measurable disease: Serum M-protein level ≥ 1.0 g/dL, or Urine M-protein level ≥ 200 mg/24 hours, or In patients without a measurable M-protein, an involved light chain level ≥ 10 mg/dL and an abnormal free light chain ratio

I meet the FDA guidelines for using talquetamab.

Ability to understand a written informed consent document, and the willingness to sign it

Interventions

• Ciltacabtagene Autoleucel
• Talquetamab

Trial Overview

The study is testing talquetamab as a 'bridging therapy' before using ciltacabtagene autoleucel (cilta-cel) in those with difficult-to-treat multiple myeloma. It's an early-phase trial focusing on safety and how well this two-step treatment approach works.

How Is the Trial Designed?

Group I: Talquetamab and Ciltacabtagene autoleucel Experimental Treatment 2 Interventions

Participants with relapsed and/or refractory multiple myeloma (RRMM) will be administered talquetamab as a bridging therapy during CAR T-cell manufacturing and then receive Ciltacabtagene autoleucel CAR T-cell infusion after which they will be followed up to six months.
