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.

Conditions

Hemophagocytic Syndromes

Outcome Measures

Primary Outcomes (1)

• Survival with a decrease in SOFA score ≥ 3 points

  Sequential Organ Failure Assessment Score varies from 0 to 4 and permit to assess organ failure. A higher score indicates better neurological function.

  At day 7

Secondary Outcomes (30)

• Overall survival in HS critically ill patients

  At 6 months

• SOFA score

  At day 1

• SOFA score

  At day 14

• SOFA score

  At day 28

• Length of stay in Intensive Care Unit

  Up to 6 months

Study Arms (1)

Interventional medicinal product

EXPERIMENTAL

Drug: Ruxolitinib

Interventions

Ruxolitinib DRUG

Oral ruxolitinib twice a day (10 mg x 2 during 28 days) in association with standard of care in HS.

• admission in the ICU
• need for symptomatic treatment of HS in relation with organ failure, as defined by SOFA score ≥ 4
• Informed consent signed:
• by the patient,
• Or informed consent signed by a family members/trustworthy person if his condition does not allow him to express his consent in written
• Or in an emergency situation and in the absence of family members/trustworthy person, the patient can be enrolled. The consent to participate to the research will be requested as soon as the condition of the patient will allow).
