Research Overview

Roxadustat

Large clinical studies support roxadustat for anemia, especially in chronic kidney disease populations. Direct VO2 max enhancement data in healthy athletes are limited, so its performance effects remain mostly inferential.

REGN1033

Human and animal studies indicate that myostatin neutralization can increase muscle size, though functional gains are often smaller than mass gains. Trevogrumab is part of the broader literature showing that selective myostatin inhibition can alter body composition in clinically meaningful ways.
