Clinical Responses

Efficacy Follow-up

Conclusions

• Induction regimens are achieving higher response rates and qualities

• Achievement of CR/MRD by flow, and in some cases by molecular testing is more common

• High dose therapy is still the standard of care for post-induction consolidation in transplant-eligible patients

Conclusions II

• Oral proteasome inhibitors & monoclonal antibodies may soon achieve approvals

• These drugs are rapidly being moved to the front-line setting in transplant-ineligible patients

• Triplet regimens are becoming the standards of care for patients with relapsed/refractory disease

• Novel agents are showing efficacy in other plasma cell dyscrasias, such as AL amyloidosis and POEMS syndrome

Remaining Questions

• What is optimal therapy for high-risk myeloma?• Is one induction regimen best for everyone, or

can we individualize therapy?• Do patients who achieve molecular MRD after

chemotherapy or transplant need consolidation and/or maintenance?

• What are the key resistance mechanisms that need to be overcome for patients in the setting of relapsed/refractory disease?
