A Study to Evaluate Preventive Treatments for GPRC5D-related Oral Events (Talisman)

June 4, 2026 updated by: Janssen Research & Development, LLC

A Phase 2, Open-label, Randomized Study to Evaluate GPRC5D-related Oral Events

The purpose of this study is to identify preventive treatments that can minimize the occurrence, severity, and duration of talquetamab-related taste changes (dysgeusia), during the prophylaxis (preventive) treatment phase, to better characterize the signs or symptoms of talquetamab-related taste changes and to better characterize the signs or symptoms of ramantamig-related taste changes.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Occurrence of Dysgeusia as Assessed by the Total Waterless Empirical Taste Test (WETT) Testing Score During the Prophylaxis Treatment Phase
Time Frame: Up to 12 months
Dysgeusia is defined as total WETT score of 25th percentile or below according to the Normative WETT-SA53 percentile table. Taste assessment will be performed using taste strips (WETT). Four concentrations (4=lowest concentration, 1=highest concentration) will be used for each taste quality: sweet, sour, salty, bitter, and umami. Each test kit contains 53 taste strips distributed in 4 packs; and each taste strip is numbered (1 through 53). Participants will use each strip sequentially and record the flavor on a score card provided. The test will result in a maximum (that is, best) total score of 53. The score will be graded by a qualified site staff into a normative percentile score using a provided chart.
Up to 12 months
Percentage of Participants With Occurrence of Severe Dysgeusia During the Prophylaxis Treatment Phase
Time Frame: Up to 12 months
Severe Dysgeusia is defined as a total WETT score of 10th percentile or below according to the normative WETT-SA53 percentile table. Taste assessment will be performed using taste strips (WETT).

Each test kit contains 53 taste strips distributed in 4 packs; and each taste strip is numbered (1 through 53). Participants will use each strip sequentially and record the flavor on a score card provided. The test will result in a maximum (that is, best) total score of 53.

The recall period is 7 days, and responses are reported using verbal and numeric rating scales. The item and scale scores are transformed to a 0 to 100 scale. A high scale score represents a higher response level. A high score for a functional scale represents a high/healthy level of functioning and a high score for the global health status represents high health related quality of life (HRQoL), but a high score for a symptom scale/item represents a high level of symptomatology/problems.
