target IDO1 · moa ido1-inhibition · failure mode target-redundant

1. premise IDO1 drives tryptophan-pathway immunosuppression that overlaps the suppression PD-1 blockade already relieves doi:10.5281/zenodo.19116937
2. premise the IDO1 inhibitor epacadostat added to PD-1 blockade failed to improve outcomes in the ECHO-301 phase-3
3. inference IDO1 inhibition contributes no independent rate-limiting step on a PD-1 backbone — target-redundant
4. prediction no pathologic complete response difference versus the control regimen
