How this list is built
We counted interventional clinical trials with a company as lead sponsor and a start date from 1 November 2023 to 31 October 2026 that list infectious disease as a studied condition; withdrawn trials are not counted. Subsidiaries and name variants are merged into the parent company ("Merck Sharp & Dohme LLC" and "Cidara Therapeutics Inc., a subsidiary of Merck & Co., Inc. (Rahway, New Jersey USA)" are counted as Merck & Co. (MSD)), and hospitals, universities and other non-company sponsors are left out. Companies with the same count share a rank, and all companies tied at the last place are shown.
Every position is set by the data alone, by the same rules for every company. Spotted something to update? Write to info@stratummarketresearch.com with the list and the line, and we correct it within two working days.
