Payments from drug & device makers
What this record shows
This record is dominated by speaking fees: $2,731,672 of the $2,906,604 with a category attached, or 94.0%. Veru Inc. accounts for 94.0% of it on its own, with 5 other manufacturers making up the rest. Reporting peaked in 2022 at $2,650,331 and has fallen 98.5% since, to $39,025 in 2025. Among medical oncology clinicians in MD with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
