Clinical consensus on treatments for transplant-ineligible newly diagnosed multiple myeloma: double-blinded Delphi panel.

Aim: Obtain clinical consensus on factors impacting first-line prescribing for transplant-ineligible (TIE) patients with newly diagnosed multiple myeloma (NDMM). Materials & methods: A double-blinded, modified Delphi panel was employed. USA-based hematologists/oncologists who treat TIE patients with NDMM were selected as expert panelists. Results: Consensus was reached that patient frailty, performance status, comorbidities, treatment efficacy, and adverse event profile affect first-line prescribing. All panelists agreed it is important to use the most efficacious treatment first; 88% of panelists considered daratumumab-containing regimens the most efficacious. Panelists agreed treatment should be continued until progression while benefits outweigh risk. Conclusion: Findings reinforce the importance of using the most efficacious regimen upfront for TIE NDMM, and nearly all panelists considered daratumumab-containing regimens the most efficacious treatment.
