We noticed that the above article carries few inaccuracies in the layout of Figure 4 and in the text of the related legend. Although the findings do not affect the overall meaning of the paper and its conclusions, still some rephrasing is deserved. We report in the table below the details of the changes related to Figure 4 and its legend, as well as the related changes in the text of the article. Moreover, in order to make the article more accurate and readable, we report below also some other minor inaccuracies we identified with the related amendments. For each amendment, a brief rationale is provided.

			Lines 23 to 39	The assessment of the effect of SDs of ETC‐206 on relative p‐eIF4E levels showed a large variability (see Figure 4). Nevertheless, a signal of the treatment effect with respect to the placebo response was observed (Figure 4a) in the initial part of the time course of the relative p‐eIF4E levels in PBMCs (i.e., ≤4 hours postdose). To better assess the magnitude of this signal and the potential relationship with the ETC‐206 plasma levels, the partial area under the ETC‐206 plasma levels (AUC PK (0–4 hour)) and the partial area under the relative p‐eIF4E levels (AUC rel. p‐eIF4E (0–4 hour)) have been computed (Figure 4b). A statistically significant correlation (P = 0.00566) has been found between these two measures, indicating that as the ETC‐206 plasma levels increase, the relative p‐eIF4E levels decrease. This finding may indicate the presence of an exposure–response relationship between ETC‐206 and a target biomarker and deserves further investigations in coming studies.	Looking at the mean relative p‐eIF4E levels a large variability for placebo‐treated subjects was observed, which is partially explained due to the low sample numbers (see Figure 4). To better explore the relationship of the relative p‐eIF4E levels in PBMCs with the ETC‐206 plasma levels, the partial area under the ETC‐206 plasma levels (AUC) and the partial area under the relative p‐eIF4E levels (AUC rel. p‐eIF4E) during the first 4 h post‐dose, have been computed (Figure 4b). Despite of the lack of statistical significance, the negative slope of the regression analysis represented a signal of treatment effect. This signal should be carefully considered given the limited measurements available and needs to be confirmed in further experiment properly designed and powered.
