A high score for disease symptoms represents a high level of symptomatology or problems. A high score for Future Perspective and Body Image represents a high/healthy level of functioning.	Up to approximately 473 weeks
Change From Baseline in HRQoL as Measured by EORTC IL52	The EORTC Quality of Life Questionnaire 20-item Multiple Myeloma module (QLQMY20) is a supplement to the QLQ-C30 instrument used in participants with multiple myeloma.

The individual component scores in the disease symptom domain are averaged and transformed linearly to a score ranging from 0 to100. A high score for disease symptoms represents a high level of symptomatology or problems. A high score for Future Perspective and Body Image represents a high/healthy level of functioning.	Up to approximately 473 weeks
