Could a drug revive immune systems in the ICU?
NCT ID NCT06694740
First seen Jun 27, 2026 · Last updated Jul 07, 2026 · Updated 2 times
Summary
This study tests whether a drug called interferon gamma can help intensive care patients whose immune systems have shut down after a severe injury or infection. The main goal is to see if it helps them spend more days alive and off a breathing machine. About 170 adults on ventilators with low immune markers will receive either the drug or a placebo.
