简要总结
This study aims to evaluate alternative dosing regimens of single-agent belantamab mafodotin in participants with relapsed or refractory multiple myeloma (RRMM) to determine if an improved overall benefit/risk profile can be achieved by modifying the belantamab mafodotin dose, schedule, or both.

结局指标
主要结局
Percentage of Participants With Grade ≥2 Corneal Events Assessed by Keratopathy Visual Acuity (KVA) Scale
时间窗: Up to 29.5 months
The KVA scale is based on the evaluation of corneal changes using slit lamp examination. This scale provides a standardized approach for evaluating the relationship between corneal health and visual acuity. KVA scale is defined as Grade 0: No keratopathy, normal visual acuity with no corneal abnormalities; Grade 1: Mild changes to the cornea with no significant loss in visual acuity; Grade 2: Moderate corneal changes with noticeable visual acuity reduction; Grade 3: Severe corneal changes with substantial visual acuity impairment; Grade 4: Very severe corneal changes leading to significant vision loss. Higher grade indicates greater severity of corneal events.
