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

Obtain clinical consensus on factors impacting first-line prescribing for transplant-ineligible (TIE) patients with newly diagnosed multiple myeloma (NDMM). A double-blinded, modified Delphi panel was employed. USA-based hematologists/oncologists who treat TIE patients with NDMM were selected as expert panelists. 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. 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.
