Participants scored each category on a scale from 1-7 ranging from super bad (score = 1) to super good (score = 7). As pre-specified by the sSAP, all participants who received suspension formulation were evaluated for palatability and acceptability of the suspension formulation, and data were summarized in an overall safety analysis set irrespective of tumor type. The palatability score based on the smell category is presented.
