Research Overview

Arenicin-1

Marine annelid peptide with strong preclinical antibacterial activity and a stable structural motif that is useful for peptide engineering.

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.
