    In summary, we report the final overall survival of the AVETUX trial and propose T cell clonality and diversity as a potential marker to predict response to chemo-immunotherapy combinations in MSS mCRC by performing a central radiological review. ClinicalTrials.gov, identifier (NCT03174405).

    Selection of PD-L1 escape variants in microsatellite stable metastatic colorectal cancer on avelumab treatment (Poster Area, Hall 4) -  Jul 28, 2022 - Abstract #ESMO2022ESMO_3208;    
    P2
    The patient received 4 cycles of FOLFIRI/cetuximab, followed by 4 cycles FOLFIRI/cetuximab + avelumab, followed by avelumab maintenance treatment for 10 weeks until end of treatment (EOT) due to progression in week 19...Together with the emergence of truncated PD-L1 variants, regulation of PD-L1 availabilty but not epitope disruption appears to be the key mechanistic principle towards PD-L1 escape. Future trials confirming this principle in other entities are warranted especially in patient subpopulations with rs396991.
