The favorable gut microbiome is the one associated with the favorable response to ipilimumab and nivolumab. The description of favorable microbiome will be based upon baseline analyses performed in patients of the placebo arm, but also in patients who met the inclusion criteria, received Ipilimumab+Nivolumab, who consented to have a baseline stool microbiota analysis, but were not included in the randomized trial.
