EValuation of the Impact of the UPLUG DEvice Onto the iNfection Rate of Indwelling Central Venous Catheters in Patients Undergoing Chronic hEmodialysis

Infections are common complications among patients on chronic haemodialysis. Haemodialysis patients with a catheter have a 2- to 3-fold increased risk of hospitalization for infection and death compared with patients with an arteriovenous fistula or graft [0]. As it is a major concern for the medical community, this clinical investigation aims at assessing, in real world conditions, the impact of the UPLUG device onto the infection rate of indwelling central venous haemodialysis catheters. UPLUG-EVIDENCE is an international, multicenter, randomised, open label trial that will evaluate the efficacy of the UPLUG device on the reduction of bacterial infections in patients undergoing chronic haemodialysis with central venous catheter (CVC). The UPLUG device has been designed to : reduce the haemodialysis catheter openings, hence potentially reducing the infectious risk, improve the lock solution infusion using a positive pressure, limiting the thrombosis risk and associated haemodialysis catheter dysfunction limit the time needed to connect and disconnect the patient, by facilitating how the different steps are operated, and even allowing a connection/disconnection with a single healthcare professional ultimately enhance patient's autonomy with ergonomics & safe procedures

A total of 464 end stage renal disease patients undergoing chronic haemodialysis and receiving a new (de novo or replacement) indwelling CVC will be randomly assigned in a 1:1 ratio to perform either standard-of-care dialysis (232) or standard-of-care dialysis associated with the UPLUG device (232). The UPLUG device consists of 2 parts : the UPLUG Port, a sterile, single use device connected to the distal Luer-Lock connectors of a regular central venous catheter. It may be connected up to 29 days and the UPLUG Disposable, a sterile, single use device indicated for use with the UPLUG Port to perform a chronic haemodialysis therapy. it will be changed at every dialysis session. Treatment period (16 weeks): W1:D1 : first connection of the UPLUG Port The patient will be seen by a nurse or an investigator at D29, D57 and D85 for UPLUG port periodical replacement, and at D113 for the definitive withdrawal of the UPLUG port. Follow-up period (29 days): A last visit (onsite or call) is planned during the definitive withdrawal of the CVC or no later than 29 days after the end of the treatment period (D113) to assess the safety and well-being of the patient

Multi-centered open labelled two-arm randomized (1:1) superiority trial. One arm will have standard dialysis, the other arm will have dialysis using the UPLUG device

UPLUG Port (changed every 29 days) and UPLUG Disposable (changed at every dialysis session) ensure the connection between a regular haemodialysis catheter and an extracorporeal circuit, and proceed to different steps of haemodialysis session without handling the Luer-Lock connectors of the haemodialysis catheter

Central haemodialysis venous catheter (CE marked) will be used within the scope of their intended purpose during the dialysis session

A clinical suspicion of bacterial infection is defined by : 1/ fever (T>37.5°C) or Or 2/ rigor Or 3/ new pre-HD hypotension (systolic arterial pressure <90mmHg) Or 4/ confusion and/or disorientation at the investigator's discretion and will lead to a confirmation of bacteraemia**: Blood culture (BC) growing the same organism from : 1/ HD catheter and 2a/ Peripheral vein And/or 2b/ Dialysis bloodline

Number of clinical suspicion of bacterial infection during the 16 weeks of the treatment period, evaluated at Day 29, Day 57, Day 85 and Day 113

A clinical suspicion of bacterial infection is defined by one of the following : 1/ fever (T>37.5°C) Or 2/ rigor Or 3/ new pre-HD hypotension (systolic arterial pressure <90mmHg) Or 4/ confusion and/or disorientation at the investigator's discretion

Number of positive blood culture during the 16 weeks of the treatment period evaluated at Day 29, Day 57, Day 85 and Day 113

Positive blood culture from one of the following : 1/ HD catheter Or 2/ Peripheral vein Or 3/ Dialysis bloodline

Number of dysfunction estimated by blood flow rate (Qb) evaluated at Day 29, Day 57, Day 85 and Day 113

Dysfunction is defined as: Qb < 200 ml/min during 30 minutes in the course of one haemodialysis session; Or Mean Qb < 250 ml/min during two consecutive haemodialysis sessions"

Adverse events defined as defectiveness of the device, defectiveness of the placement, thrombosis events and infections

Number of infections other than bacterial during the 16 weeks of treatment period evaluated at Day 29, Day 57, Day 85 and Day 113

Patient satisfaction is assessed through : a specific UBIPLUG questionnaire and a questionnaire SF-36 (Short-Form 36 Health Survey)

Number of patients with at least one bacterial infection during the 16 weeks of treatment period evaluated at Day 29, Day 57, Day 85 and Day 113

A clinical suspicion of bacterial infection is defined by : 1/ fever (T>37.5°C) or Or 2/ rigor Or 3/ new pre-HD hypotension (systolic arterial pressure <90mmHg) Or 4/ confusion and/or disorientation at the investigator's discretion and will lead to a confirmation of bacteraemia: Blood culture (BC) growing the same organism from : 1/ HD catheter and 2a/ Peripheral vein And/or 2b/ Dialysis bloodline

Time spent by session by the nurse to connect the patient at Day 1, Day 29, Day 57, Day 85 and Day 113
