Extracellular Degraders

Pioneering the First Extracellular Protein Degraders in the Clinic

Biohaven’s MoDETM and TRAPTM degraders represent a new class of therapeutics that selectively remove disease driving proteins from circulation.

Biohaven R&D Day 2026 at Yale School of Management

Our goal is to address the root cause of immune mediated disease while preserving healthy immune function. By enabling precise, systemic elimination of pathogenic targets, extracellular degraders offer a differentiated approach beyond conventional inhibition and broad immunosuppression.

MoDE

MoDE

Target classes of proteins implicated in disease pathogenesis

MoDEs target pathogenic protein classes, enabling intervention across diseases driven by shared biological mechanisms.
TRAP

TRAP

Selectively remove specific disease‑causing proteins

TRAPs enable highly selective removal of defined pathogenic targets, preserving healthy immune components while directly addressing the driver of disease

Precisely balanced components synthesized for optimal efficacy, safety, and product profile
