Percentage of Participants With Occurrence of Dysgeusia as Assessed by the Total Waterless Empirical Taste Test (WETT) Testing Score During the Prophylaxis Treatment Phase
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.
Time frame: Up to 12 months
Percentage of Participants With Occurrence of Severe Dysgeusia During the Prophylaxis Treatment Phase
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). 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.

Time frame: Up to 12 months
Time to the First Onset of Severe Dysgeusia During the Prophylaxis Treatment Phase
Time to the first onset of severe dysgeusia is defined as time from the first dose date of talquetamab to the first onset date of severe dysgeusia according to the total WETT score. For participants without severe dysgeusia, time to the first onset will be censored. 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.

Change From Baseline in the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 items (EORTC-QLQ-C30) Domains Scores Over Time
The EORTC-QLQ-C30 includes 30 items that make up 5 functional scales (physical, role, emotional, cognitive, and social), 1 global health status scale, 3 symptom scales (pain, fatigue, and nausea/vomiting), and 5 single symptom items (dyspnea, insomnia, appetite loss, constipation, and diarrhea) and a single impact item (financial difficulties). 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.
Time frame: From Baseline, up to 12 months (Cohorts A to E); up to 24 months (for Cohort F)
