Concomitant Care Section

SPIRIT 2025 protocol guidance requires clarity about relevant concomitant care and interventions that are permitted or prohibited during the trial so treatment contrast and participant management can be understood. Requirements depend on the intervention, disease area, protocol, safety needs, sponsor, and jurisdiction. Do not imply that ordinary necessary care should be withheld merely to simplify a trial.
