How are the KOL Pulse Multiple Myeloma rankings determined?

Engagement around the major oncology meetings (ASH, ASCO, EHA and the International Myeloma Society meeting) counts most. Only physicians are ranked, and only engagement from physicians counts.

It is a relative score out of 100. The top-ranked multiple myeloma physician worldwide scores 100, and every other physician is scored against that leader. The same score appears on the US and Global lists, so the two are directly comparable.

How often are the rankings updated?

KOL Pulse updates the Multiple Myeloma rankings after each major meeting. This page was last updated November 11, 2026.

Yes. Each ranked US physician links to a KOL Pulse profile with the clinical trials they discussed, their 2025–26 presentations, the colleagues who amplify them and their CMS Open Payments summary.
