Phase 2

• Conditions: Multiple myeloma; D009101

• Registration Number: JPRN-jRCTs041180048
• Lead Sponsor: RI MASAKI

Brief Summary

Modified BLd regimen showed a favorable response rate (60% of PR or better), and well tolerability of modified BLd regimen with less non-hematological toxicities and occurrence of PN. Thus, we suggested that the trial therapy was effective. This study supports the front-line therapy using a proteasome inhibitor and immunomodulatory drugs for the elderly or unfit/frail patients with MM in a transplant-ineligible setting.
