Lead Sponsor

Brief Summary

The purpose of this study is to evaluate the efficacy and safety of salvage treatment with carfilzomib/lenalidomide/dexamethasone (KRD) followed by 2nd autologous stem cell transplantation (ASCT) and lenalidomide maintenance in patients with relapsed myeloma after 1st ASCT.

Detailed Description

This is a single-arm phase II study to assess the efficacy and safety of KRD followed by 2nd ASCT - lenalidomide maintenance for 18 months in patients with relapsed multiple myeloma after 1st ASCT who are 70 years of age or younger. A total of 58 participants will be recruited. As a re-induction therapy 6 cycles of KRD (K, 27mg/m2, D1,2,8,9,15,16; R, 25 mg, D1-21; D, 40mg weekly, every 28 days) will be administered. If a patient achieves at least partial response, 2nd ASCT + lenalidomide 10mg for 18 months will be proceeded. Study will be continued until disease progression, unacceptable toxicity, or completion of pre-planned schedule. Response will be assessed using the International Myeloma Working Group(IMWG) response criteria and the safety profiles will be described using the NCI-CTCAE v5.0. Participants who discontinue therapy will be followed every 3 months for 3 years if they are on subsequent treatment, disease-free or dead.
