Aggregate Safety Assessment Planning in Clinical Trial Drug Development is new, not well understood, and actively evolving. In our 1st survey (https://doi.org/10.1007/s43441-026-01055-2), we could not ask simple questions and expect well-defined answers; so we conducted interviews. Our sample was small (n = 21), but the data from each of the respondents was rich. Now that we understand the key questions and likely answers, we would like to conduct a much larger and more representative survey of the industry with streamlined questions and standardized answers. This will provide a more structured understanding of where the industry is and where it is headed.
