JAK Inhibitor in Acquired Hemophagocytic synDrome in the Intensive Care Unit
- Registration Number
- NCT06244862
- Lead Sponsor
- Assistance Publique - Hôpitaux de Paris
- Brief Summary
Hemophagocytic syndrome (HS) is a rare condition that can be responsible for severe organ failure. Therapeutic guidelines are mainly based on observational studies and expert opinions: no therapeutic advance has been developed for years, explaining why mortality in HS remains high (Intensive Care Unit mortality ranging from 40 to 70%). If etoposide remains the gold standard in critically ill HS patients, nearly 20% of patients are refractory to this therapy: treatment escalation is common, most often requiring the administration of intensive treatments generating high toxicity. Ruxolitinib is the first approved JAK inhibitor. It has been associated with improvement of HS manifestations and survival in a pre-clinical murine model. Data in humans are scarce but promising.
The aim is to demonstrate that ruxolitinib, in association with standard of care, may reverse organ failure (as represented by Sequential Organ Failure Assessment (SOFA) score) better than standard of care alone in critically ill patients with acquired HS.

- Primary Outcome Measures
Name Time Method Survival with a decrease in SOFA score ≥ 3 points At day 7 Sequential Organ Failure Assessment Score varies from 0 to 4 and permit to assess organ failure. A higher score indicates better neurological function.
- Secondary Outcome Measures
Name Time Method SOFA score At day 28 Sequential Organ Failure Assessment Score varies from 0 to 4 and permit to assess organ failure. A higher score indicates better neurological function.
