Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults with relapse or refractory multiple myeloma who have previously been treated with multiple classes of therapies and have a stable performance status.

Probably not a fit

Patients who have contraindications to talquetamab or those with severe neurological conditions may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study aims to identify preventive treatments that can reduce the occurrence, severity, and duration of taste changes (dysgeusia) associated with talquetamab in patients with relapse or refractory multiple myeloma. Participants will receive various prophylactic treatments during the preventive phase to assess their effectiveness. The study will also characterize the signs and symptoms related to talquetamab-induced taste changes. It is designed as a Phase 2 interventional trial to gather data on these preventive measures.

Why it matters

Potential benefit: If successful, this study could significantly improve the quality of life for multiple myeloma patients undergoing treatment with talquetamab by minimizing unpleasant taste changes.

How similar studies have gone: While there is limited information on similar studies specifically targeting talquetamab-related taste changes, the approach of preventive treatment in oncology has shown promise in other contexts.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Multiple myeloma (MM) according to IMWG diagnostic criteria
* Were triple-class exposed (received prior treatment with a PI, an IMiD, and anti CD38 mAb)
* Documented evidence of progressive disease based on investigator's determination of response by IMWG criteria on or after their last regimen
* Have an Eastern Cooperative Oncology Group-performance status (ECOG-PS) of 0 or 1 at screening. Participants with ECOG-PS 2 or 3 are eligible for the study if the ECOG-PS score is related to stable physical limitations (e.g., wheelchair-bound due to prior spinal cord injury) and not related to multiple myeloma or associated therapy
* Be willing and able to adhere to the lifestyle restrictions specified in the protocol

Exclusion Criteria:

* Contraindications or life-threatening known allergies, hypersensitivity, or intolerance to any study drug or its excipients
* Stroke, transient ischemic attack, or seizure within 6 months prior to screening
* Any of the following within 6 months prior to the first dose of study treatment: severe or unstable angina, myocardial infarction; major thromboembolytic event (e.g., pulmonary embolism, cerebrovascular accident), clinically significant ventricular arrythmia or heart failure New York Heart Association functional classification Class III or IV. Uncomplicated deep vein thrombosis is not considered exclusionary
* Major surgery or had significant traumatic injury within 2 weeks prior to the start of administration of study treatment, or will not have fully recovered from surgery, or has major surgery planned during the time the participant is expected to be treated in the study or within 2 weeks after administration of the last dose of study treatment
* A WETT score indicating severe dysgeusia at screening and confirmed prior to randomization. Also unresolved/severe dysgeusia referred by the participant or a finding in the physical examination/oral cavity inspection. Some examples include leukoplakia, prior mouth cancers, extensive dental caries, severe periodontitis, active oral infections, candidiasis, parotic gland removal, or radiotherapy with resultant xerostomia
