Dr. Sands disclosed multiple ties to private companies, including research support, consulting, data safety monitoring, travel, a gift, and a stock option.

Others reported employment, variously, with Prometheus and/or Merck, Spyre Therapeutics, and Mirador Therapeutics, or patent holding for IBD drugs. Dr. Hou had no relevant competing interests to disclose but will participate in the phase 3 trial.
