Recovery From Acute Immune Failure in Septic Shock by Immune Cell Extracorporeal Therapy

Phase 2

Recruiting

• Conditions: Sepsis, Severe
• Interventions: Biological: ARTICE

• Registration Number: NCT05442710
• Lead Sponsor: Artcline GmbH

Brief Summary

Evaluation of a novel therapy approach for severe sepsis patients. Subjects randomized into the treatment arm receive treatment with an immune cell perfusion system on top of standard care.

This may contribute to the improvement of the impaired organ function of septic shock patients by assisting the impaired immune system (immune competence enhancement = ARTICE)

It considers five dimensions including mobility, self-care, usual activities, pain/discomfort, and anxiety/depression at 5 levels: no problems, slight problems, moderate problems, severe problems and extreme problems. The answers result in a 1-digit number for each dimension. The digits (1= no problem to 5=extreme problems) can be combined into a 5-digit number that describes the patient's health state. 11111 indicates no problems on any of the five dimensions.; The EQ VAS visual analogue scale records the patient's self-rated health. The endpoints are labelled 'The best health you can imagine' (=100) and 'The worst health you can imagine' (=0).
