Brief Summary:

This study will evaluate the safety and tolerability profile of belantamab mafodotin when administered in combination with approved regimens of either Lenalidomide Plus Dexamethasone [Len/Dex (Arm A)] or Bortezomib Plus Dexamethasone [Bor/Dex (Arm B)] in participants with RRMM, i.e., those who have relapsed or who are refractory to at least 1 line of approved therapy. Part 1 of the study will be a dose escalation phase to evaluate the safety and tolerability of up to 3 dose levels and up to 2 dosing schedules of belantamab mafodotin in combination with the two standard of care (SoC) regimens. Part 2 will further evaluate the safety and preliminary clinical activity of belantamab mafodotin at selected dose levels and dosing schedules in combination with Len/Dex or Bor/Dex.

A total of 152 evaluable participants will be enrolled in the study with up to 27 in Part 1 and up to 125 in Part 2. Participants receiving treatment Arm A, may continue combination treatment until the occurrence of progressive disease (PD), intolerable adverse events (AEs ), consent withdrawal, death or end of study. The participants receiving treatment Arm B, may continue combination treatment for a total of up to 8 cycles. After 8 cycles of combination therapy, the participants will continue treatment with belantamab mafodotin, as a monotherapy until the occurrence of PD, intolerable AEs, consent withdrawal, death or end of study.

The OSDI has demonstrated good reliability, validity, sensitivity, and specificity, and can be used as a complement to other clinical and subjective measures of dry eye disease by providing a quantifiable assessment of dry eye symptom frequency and the impact of these symptoms on vision-related functioning.

    EORTC QLQ-C30, is a 30-item questionnaire containing both single- and multi-item measures. These include five functional scales (Physical, Role, Cognitive, Emotional, and Social Functioning), three symptom scales (Fatigue, Pain, and Nausea/Vomiting), a Global Health Status/QoL scale, and six single items (Constipation, Diarrhea, Insomnia, Dyspnea, Appetite Loss, and Financial Difficulties). Scores for each scale and single-item measure. A high score for functional scales and for Global Health Status/QoL, represent better functioning ability or HRQoL, whereas a high score for symptom scales and single items represents significant symptomatology.

  26. Change from Baseline in HRQoL as measured by EORTC, 20-Item Multiple Myeloma Module (QLQ-MY20), Part 1 and 2 [ Time Frame: Baseline and Up to 4.5 years ]
    QLQ-MY20, module comprises 20 questions that address four myeloma-specific HRQoL domains: Disease Symptoms, Side Effects of Treatment (DSSE), Future Perspective, and Body Image (FPBI). Three of four QLQ-MY20 domains, are multi-item scales: Disease Symptoms (bone aches or pain, back pain, hip pain, arm or shoulder pain, chest pain, and pain increasing with activity); Side effects of treatment (drowsiness, thirst, feeling ill, dry mouth, hair loss, upset by hair loss, tingling hands or feet, restlessness/agitation, acid indigestion/heartburn, and burning or sore eyes); and Future perspective (worry about death and health in future, and thinking about illness). The Body Image scale is single-item scale that addresses physical attractiveness. A high score for DSSE, represents a high level of symptomatology or problems, whereas high score for FPBI, represents better outcomes.
