This study investigates the safety, tolerability and performance of the NucleoCapture extracorporeal apheresis device in patients with sepsis and respiratory failure. Sepsis is a common condition in hospital settings and is associated with high rates of morbidity and mortality and despite ongoing development in the treatment and supportive care of sepsis, mortality remains considerable.~cfDNA/NET therapeutic apheresis with NucleoCapture is indicated for the treatment of sepsis and for the treatment/prevention of septic shock. Participants will be randomised to receive either standard of care (SOC) or SOC plus NucleoCapture treatment, SOC will be according to the current guidelines described by the Surviving Sepsis Campaign: international guidelines for the management of sepsis and septic shock. Participants in the SOC plus NucleoCapture arm will receive one treatment session with NucleoCapture per day, for the first three days. Each treatment session with NucleoCapture will last for up 6 hours, aiming to treat 4.5 plasma volumes. Treatment sessions with NucleoCapture treating less than 3.5 plasma volumes will be counted as incomplete and the treatment session will be repeated on the following day, up to day 5 maximum.~Assessments and tests will take place for all participants whilst in Intensive Care Unit (ICU) on days 1 to 5, day 7, day 14, day 21 and day 28. Participants transferred to ward-based care before day 28 will receive no further study assessment visits from the point of transfer to ward-based care, apart from day 28 in which participants will receive a final study assessment visit.
This is a prospective, multinational, multicentre, randomised, parallel-group, open-label study to assess the safety, tolerability and performance of the NucleoCapture extracorporeal apheresis device in the reduction of circulating cell-free DNA (cfDNA)/Neutrophil Extracellular Traps (NETs) in sepsis patients.
