Study of Single Agent Belantamab Mafodotin Versus Pomalidomide Plus Low-dose Dexamethasone (Pom/Dex) in Participants With Relapsed/Refractory Multiple Myeloma (RRMM)

This open-label, randomized study for evaluating the efficacy and safety of single agent belantamab mafodotin when compared to pom/dex in participants with RRMM. Participants will be randomized in a 2:1 ratio to receive either single agent belantamab mafodotin or pom/dex. Belantamab mafodotin will be administered on Day 1 (D1) at every 3 weeks (Q3W) schedule. Pomalidomide will be administered daily on Days 1 to 21 of each 28-day cycle, with dexamethasone administered once weekly (Days 1, 8, 15, and 22). Participants in both arms will be treated until disease progression, death, unacceptable toxicity, withdrawal of consent, and lost to follow-up or end of study, whichever comes first.

The PRO-CTCAE includes an item library of 124 items representing 78 symptomatic toxicities drawn from the CTCAE. It includes symptomatic toxicities drawn from the CTCAE like blurred vision, chills, constipation, decreased appetite, fatigue, general pain, mouth/throat sores, nausea, nosebleed, shortness of breath, vomiting, watery eyes, cough, itchy, loose/watery stools, Numb/Tingling Hands/Feet (N/T H/F), Pain/Burning (P/B) and Problems Tasting Food/Drink (Prob Tasting F/D) .

A score of 0 indicates no symptom or interference, while higher score of 4 signify increasing severity, frequency, and interference with daily activities.

  20. Change From Baseline (CFB) in Ocular Surface Disease Index (OSDI) Total Score

    Time frame: Baseline (Day 1) and Up to approximately 263 weeks

    OSDI is 12-item patient-reported outcomes questionnaire designed to provide rapid assessment of range of ocular surface symptoms, including symptoms related to chronic dry eye, severity, and impact on patient's ability to function. In addition to an overall score, there are three subscales of OSDI: ocular symptoms, vision-related function, and environmental triggers. OSDI items are scored on a 0 to 4 Likert-type scale, where 0 = None of the time and 4 = All of the time. Total OSDI score = ([sum of scores for all questions answered×100]/[total number of questions answered×4]). Subscale scores are computed similarly with only questions from each subscale used to generate its own score. Any subscales analyzed separately would also have a maximum possible score of 100. A score of 100=to complete disability, while a score of 0=to no disability. Decrease in score from baseline means improvement

  21. Change From Baseline (CFB) in European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire 30-item Core Module (EORTC QLQ-C30) Score.

    Time frame: Baseline (Day 1), every three weeks(Q3W) starting from week 4 until week 238, End of Treatment (~242 weeks) and Follow up (~ 263 weeks)

    The EORTC QLQ-C30 includes 30-items with single and multi-item scales. These included five functional scales (physical functioning [PF], role functioning [RF], emotional functioning [EF] cognitive functioning [CF] and social functioning [SF]), three symptom scales (fatigue, nausea/vomiting [N/V] and pain), a global health status (GHS)/ Quality-of-Life (QoL) scale, and six single items (dyspnea, insomnia, appetite loss [AL], constipation, diarrhea and financial difficulties [FD]). Response options are 1 to 4. Scores were averaged and transformed to 0 to 100, a high score for functional scales/ GHS/QoL represent better functioning ability or health-related quality-of-life (HRQoL), whereas a high score for symptom scales/ single items represent significant symptomatology. Baseline was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits.

  22. Change From Baseline (CFB) in EORTC QLQ 20-item Multiple Myeloma Module (MY20) Score

    Time frame: Baseline (Day 1), every three weeks(Q3W) starting from week 4 until week 238, End of Treatment (~242 weeks) and Follow up (~263 weeks)

    The EORTC QLQ-MY20 is a supplement to the QLQ-C30 instrument used in participants with multiple myeloma. The module comprised of 20 questions that addressed four myeloma-specific HRQoL domains: disease symptoms (DS), side effects of treatment (SET), future perspective (FP) and body image (BI). Responses are 1 to 4. Scores were averaged and scales were transformed to 0 to 100 scale. A high score for disease symptoms and side effects of treatment represented a high level of symptomatology or problems, whereas a high score for future perspective and body image represented better outcomes. Baseline was defined as the latest pre-dose assessment with a non-missing value, including those from unscheduled visits.

  23. Change From Baseline (CFB) in EORTC IL52 Score

    Time frame: Baseline (Day 1), every three weeks(Q3W) starting from week 4 until week 238

    European Organization for Research and Treatment of Cancer Item Library 52 (EORTC-QLQ-IL52) is disease symptoms domain from EORTC Quality of Life Questionnaire 20-item Multiple Myeloma module) (EORTC QLQ-MY20). Disease symptoms domain of IL52 contain 6 items covering following concepts: bone aches or pain, back pain, hip pain, arm or shoulder pain, chest pain, and pain increasing with activity. IL52 items are scored on 1 to 4 Likert-type scale, where 1 = Not at all, 2 = A little, 3 = Quite a bit, and 4 = Very much. A raw score is then calculated as mean of completed item responses across 6 disease symptom items. For symptom scales, this raw score is linearly transformed to a 0 to 100 scale using the formula: [(raw score - 1) / 3] × 100. Under this approach, a score of 0 indicates no symptoms across items, while a score of 100 indicates the highest level of symptom burden. Accordingly, higher scores indicate greater symptom burden or worse disease symptoms

  24. Number of Participants With Minimal Residual Disease (MRD) Negativity Rate

    Time frame: Up to approximately 263 weeks

    MRD negativity rate is defined as the percentage of participants who are MRD negative by Next generation sequencing (NGS) method. The number of participants with MRD negativity has been presented
