What You Need to Know Before You Apply

What is the purpose of this trial?

The purpose of this study is to evaluate the efficacy and safety of talquetamab in participants with relapsed or refractory multiple myeloma at the recommended Phase 2 dose(s) (RP2Ds) (Part 3).

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, it mentions that any side effects from previous cancer treatments should be resolved to a certain level before starting the study drug.

Is Talquetamab safe for humans?

Talquetamab has been tested in early clinical trials for multiple myeloma, showing it is generally well-tolerated with some side effects like skin, mouth, and nail issues. It has fewer infections compared to similar treatments, indicating a favorable safety profile. ^{1 2 3 4 5}

How is the drug Talquetamab different from other treatments for multiple myeloma?

Talquetamab is unique because it is a first-in-class bispecific antibody that targets a specific protein (GPRC5D) found on cancerous plasma cells and recruits T cells to attack these cells, offering a new approach for patients with relapsed or refractory multiple myeloma. ^{1 2 3 4 6}

What data supports the effectiveness of the drug Talquetamab for treating multiple myeloma?

In the MonumenTAL-1 trial, nearly 75% of patients with relapsed or refractory multiple myeloma experienced significant anticancer effects from Talquetamab, a drug that targets specific proteins on cancer cells and activates the immune system to fight the cancer. ^{1 2 3 4 5}

Participants will receive talquetamab SC biweekly at a RP2D selected after review of safety, efficacy, PK, and pharmacodynamic data from Part 1 and Part 2 of this study. Participants in this cohort will receive tocilizumab prophylaxis for cytokine release syndrome (CRS) including all outpatient dosing. Participants will transition to OLE upon communication by the sponsor. Upon approval of amendment 19 and notification from the sponsor, participants will transition to the LTE and will continue to receive study treatment.

Group III: Part 3: Cohort C (Talquetamab) Experimental Treatment 1 Intervention

Cohort C will enroll participants with multiple myeloma who have previously received \>= 3 prior lines of therapy and have not been exposed to T cell redirection therapies. Participants will receive talquetamab SC biweekly at a RP2D selected after review of safety, efficacy, PK, and pharmacodynamic data from Part 1 and Part 2 of this study. All participants (ongoing and those who are in follow-up) will transition to OLE phase and will continue to receive the study treatment. Upon approval of amendment 19 and notification from the sponsor, participants will transition to the LTE and will continue to receive study treatment.

Group IV: Part 3: Cohort B (Talquetamab) Experimental Treatment 1 Intervention

Cohort B will enroll participants with multiple myeloma who have previously received \>= 3 prior lines of therapy and have been exposed to T cell redirection therapies. Participants will receive talquetamab subcutaneously (SC) at a recommended Phase 2 dose (RP2D) selected after review of safety, efficacy, PK, and pharmacodynamic data from Part 1 and Part 2 of this study. All participants (ongoing and those who are in follow-up) will transition to OLE phase and will continue to receive the study treatment. Upon approval of amendment 19 and notification from the sponsor, participants will transition to the LTE and will continue to receive study treatment.

Group V: Part 3: Cohort A (Talquetamab) Experimental Treatment 1 Intervention

Cohort A will enroll participants with multiple myeloma who have previously received greater than or equal to (\>=) 3 prior lines of therapy and have not been exposed to T cell redirection therapies. Participants will receive talquetamab subcutaneously (SC) at a recommended Phase 2 dose (RP2D) selected after review of safety, efficacy, PK, and pharmacodynamic data from Part 1 and Part 2 of this study. All participants (ongoing and those who are in follow-up) will transition to open-label extension (OLE) phase and will continue to receive the study treatment. Upon approval of amendment 19 and notification from the sponsor, participants will transition to the long-term extension (LTE) and will continue to receive study treatment.

Published Research Related to This Trial

Talquetamab, a bispecific T-cell engager targeting GPRC5D and CD3, has received accelerated approval in the USA and conditional marketing authorization in the EU for treating adults with relapsed or refractory multiple myeloma, highlighting its potential as a new treatment option.

This approval marks a significant milestone in the development of talquetamab, indicating its efficacy and safety in addressing a challenging form of cancer that has not responded to previous treatments.

Talquetamab: First Approval. Keam, SJ.[2023]

In the MonumenTAL-1 trial, nearly 75% of the 288 patients with relapsed/refractory multiple myeloma showed significant anticancer effects from the investigational drug talquetamab.

Talquetamab is a first-in-class bispecific antibody that targets GPRC5D on malignant plasma cells while sparing normal cells, effectively activating T cells to mount an immune response against the cancer.

MonumenTAL Results for Talquetamab in Myeloma. [2023]

Talquetamab, a bispecific antibody targeting GPRC5D and CD3, shows similar efficacy and durability of response in treating relapsed or refractory multiple myeloma compared to teclistamab, the first bispecific antibody approved for this condition.

While talquetamab has a lower incidence of infections than teclistamab, it presents unique side effects related to skin, oral, and nails, yet remains a well-tolerated and effective treatment option for patients with heavily pretreated multiple myeloma.

Talquetamab in multiple myeloma. Liu, L., Krishnan, A.[2023]

In the phase 1 MonumenTAL-1 study involving patients with refractory or relapsed multiple myeloma, two doses of talquetamab (405 μg/kg weekly and 800 μg/kg every other week) were found to be well tolerated, with most side effects being mild or moderate, including cytokine release syndrome (CRS).

The treatment showed promising efficacy, with most participants experiencing a reduction in cancer signs and a median duration of response of 8-10 months, indicating talquetamab's potential as a new option for patients who have not responded to other therapies.

Three new bispecific antibodies—teclistamab, elranatamab, and talquetamab—have received accelerated FDA approval for treating relapsed/refractory multiple myeloma, indicating their potential efficacy in this challenging condition.

While these agents show promise, the medical community is currently awaiting results from randomized phase III clinical trials to better understand their effectiveness compared to standard treatments.

Monoclonal antibodies (MoAbs) like elotuzumab and daratumumab, which target specific antigens (CS1 and CD38) found in over 90% of multiple myeloma patients, show promising anti-myeloma effects, especially when combined with lenalidomide.

The article reviews various emerging MoAbs for multiple myeloma, highlighting their potential in improving treatment outcomes, although multiple myeloma remains largely incurable.
