target PD-L1 · moa checkpoint-inhibition · failure mode acquired-resistance-rechallenge

  1. premise this regimen re-exposes PD-L1 after the tumour has already progressed on PD-(L)1 therapy doi:10.5281/zenodo.19116937
  2. premise the resistance that caused the prior progression persists at rechallenge; the CONTACT-03 phase-3 showed no benefit from checkpoint rechallenge
  3. inference re-engaging the same target the tumour already escaped covers no new step — acquired resistance is not addressed
  4. prediction overall survival negative versus control

Evidence: doi:10.5281/zenodo.19116937
