What was measured

Percentage of participants who achieved ≥ VGPR and MRD negative status at a sensitivity of 10-⁵ at any time point within 3 months prior to achieving at least VGPR until the time of PD/death. MRD in the bone marrow will be measured using both next generation sequencing (NGS) techniques measuring immunoglobulin gene rearrangements of the malignant clone. MRD will be reported with a sensitivity of 10-⁴, 10-⁵, and 10-⁶ nucleated cells. The primary analysis for MRD negative response will use the sensitivity of 10-⁵. MRD = Minimal Residual Disease PD = Progressive Disease VGPR = Very good partial response.
