Journal, MSi-H Biomarker, PD(L)-1 Biomarker, IO biomarker, Metastases: Translational analysis and final efficacy of the AVETUX trial - Avelumab, cetuximab and FOLFOX in metastatic colorectal cancer. (Pubmed Central) - Jan 7, 2023 P2 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.

[VIRTUAL] O07: INTERIM ANALYSIS OF THE AVETUXIRI TRIAL: AVELUMAB COMBINED WITH CETUXIMAB AND IRINOTECAN FOR TREATMENT OF REFRACTORY MICROSATELLITE STABLE (MSS) METASTATIC COLORECTAL CANCER (mCRC) – A PROOF OF CONCEPT, OPEN LABEL, NON-RANDOMIZED PHASE IIA STUDY. (mC () - Feb 23, 2021 - Abstract #BWG2021BWG_54; P2a Methods AVETUXIRI (NCT03608046) is a multicenter academic study recruiting MSS, BRAFV600E wt, mCRC patients (pts) refractory to standard treatment (fluoropyrimidine, oxaliplatin, irinotecan and anti-EGFR treatment if RAS wt tumor) in 2 cohorts (cohort A: RAS wt – cohort B: RAS mut)...Nevertheless, encouraging data of DCR, PFS and OS observed in RAS mut cohort allow the opening of a new cohort for RAS-mut mCRC (cohort C) with PFS as primary endpoint. A high-Immunoscore was associated with treatment benefit.
