CHORDOMA-IO-MIGLIORINI

Regimen

Experimental
Anti-PD-1 therapy (nivolumab or pembrolizumab) off-label compassionate-use dosing
Control
none (case series)

Population

Three relapsed advanced chordoma patients after failure of surgery, radiotherapy, and prior systemic therapy (including imatinib)

Key finding

First report of any clinical response to immunotherapy in chordoma. Generated the hypothesis that chordoma — despite being a low-TMB tumor — has enough PD-L1 and infiltrating lymphocytes to sometimes respond to PD-1 blockade.
