Abstract 5105

Background

The NIVOREN GETUG-AFU 26 study reported safety and efficacy of nivolumab in patients with RCC in a “real world setting”. A translational research program was launched to characterize immune cell populations in fresh whole blood at baseline and after 2 months of treatment (C3) to determine association with high-grade toxicity and clinical outcome.

Methods

Absolute number of 106 immune cell populations were analysed in patients treated at a single institution as part of the NIVOREN GETUG-AFU 26 in fresh whole blood using dry formulation panels for multicolor flow cytometry. Predefined clinical endpoints were 6-month grade 3-4 toxicity (treatment related adverse event, TRAE) occurrence and 6-month disease progression occurrence. Missing values were imputed using multivariate imputation by chained equations. Multivariate differential count analysis was done using the DESeq2 R package.

Results

Overall 44 patients were included in this fresh whole blood immune-monitoring. Higher occurrence of grade 3-4 TRAE at 6 months was observed in patients with lower number of CD4+PD-1neg4.1BB+ T cell (non-exhausted activated CD4 T cells) counts at baseline (log2 fold change (LFC) = -1.993 95% confidence interval (95%CI)[-2.172; -1.815] ) and with lower number of CD56+ T cells (NKT cells) at C3 (LFC = -1.464 95%CI[-1.597; -1.331]). Higher occurrence of disease progression at 6-month was observed in patients with lower number of CD4+PD-1posCD69+ T cells (exhausted activated CD4 T cells) (LFC = -1.186 95%CI[ -1.308; -1.064 ]) and with higher number of CD4+CD244+ T cells (exhausted CD4 T cells) (LFC = 1.686 95%CI[ 1.533; 1.840]) at baseline. No immune cell populations were associated with the occurrence of a 6-month progression during the course of nivolumab (C3).

Conclusions

Fresh whole blood monitoring at baseline and after 2 months of nivolumab identified immune cell populations associated with grade 3-4 TRAE (CD4+PD-1neg4.1BB+ T cells and CD56+ T cells) and disease progression (CD4+PD-1posCD69+ T cells and CD4+CD244+ T cells). Functional analyses and external validation are ongoing.
