A Trial of Adjunctive Fludrocortisone (50mcg, 100mcg or Placebo) in Critically Ill Patients With Septic Shock Receiving Hydrocortisone, Evaluating Survival and Functional Recovery and the Influence of Transcriptomic Response

Sponsor: The George Institute

Summary

The FLUDRO-SHOCK trial is a large international randomised controlled double-blinded study aiming to improve treatment for people with septic shock, a life-threatening condition caused by severe infection. Patients with septic shock receive a steroid called hydrocortisone, but it is unclear whether adding another steroid, fludrocortisone, improves their chances of recovery and survival. This study will test two doses of fludrocortisone (50 mcg and 100 mcg) against a placebo to see which works best. It will also explore whether a person's unique immune response, based on their genes, affects how well the treatment works. The trial will involve up to 2,200 critically ill adults in intensive care units across Australia and other countries. Researchers will track survival, organ recovery, and quality of life for up to a year. The goal is to find the most effective and personalised way to use steroids in septic shock, potentially saving lives and improving long-term outcomes.
