Reprogram Protein Function

Control phosphorylation to activate, stabilize, relocate, or degrade proteins. Create new therapeutic possibilities by precisely rewiring protein behavior.

Restore Protective Proteins

Increase the expression of protective proteins that are underactive in disease. Replenish beneficial proteins without gene editing or gene therapy.

Eliminate Disease Drivers

Selectively remove disease-causing proteins through targeted degradation. Clinical-stage lead program: PHT-776, an oral IRAK4 degrader.
